The present disclosure relates to various surgical systems. Surgical procedures are typically performed in surgical operating theaters or rooms in a healthcare facility such as, for example, a hospital. A sterile field is typically created around the patient. The sterile field may include the scrubbed team members, who are properly attired, and all furniture and fixtures in the area. Various surgical devices and systems are utilized in performance of a surgical procedure.
Furthermore, in the Digital and Information Age, medical systems and facilities are often slower to implement systems or procedures utilizing newer and improved technologies due to patient safety and a general desire for maintaining traditional practices. However, often times medical systems and facilities may lack communication and shared knowledge with other neighboring or similarly situated facilities as a result. To improve patient practices, it would be desirable to find ways to help interconnect medical systems and facilities better.
In one aspect the present disclosure provides a method for adaptive control of surgical network control and interaction. The surgical network comprises a surgical feedback system. The surgical feedback system comprises a surgical instrument, a data source, and a surgical hub configured to communicably couple to the data source and the surgical instrument. The surgical hub comprises a control circuit. The method comprises receiving, by the control circuit, information related to devices communicatively coupled to the surgical network; and adaptively controlling, by the control circuit, the surgical network based on the received information.
In another aspect the present disclosure provides a method for adaptive feedback and control of a surgical system. The surgical system comprises a surgical instrument, a data source, and a surgical hub configured to communicably couple to the data source and the surgical instrument. The surgical hub comprises a control circuit. The method comprises: receiving, by the control circuit, information related to devices communicatively coupled to the surgical system; and adaptively adjusting, by the control circuit, an operating parameter of a device communicatively coupled the surgical system based on the received communicated recommendation.
In another aspect the present disclosure provides a method for adaptively controlling a surgical network based on validating data purportedly generated in a surgical procedure. The surgical network comprises a medical hub, at least one remote server communicatively coupled to the medical hub, and a medical instrument communicatively coupled to the medical hub. The system is configured to access the data, validate the data to determine if the data is validly generated by the surgical procedure, determine that the data contains at least one flaw or error, and improve data integrity by preventing the at least one flaw or error from being integrated into a larger dataset associated with the at least one remote server. The method comprises: receiving, by the server, information related to a surgical procedure from a device communicatively coupled to the surgical network; validating, by the server, the received information; and adaptively adjusting, by the server, the surgical network based on the received information.

Other types of robotic systems can be readily adapted for use with the surgical system 102. Various examples of robotic systems and surgical tools that are suitable for use with the present disclosure are described in U.S. Provisional Patent Application Ser. No. 62/611,339, titled ROBOT ASSISTED SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is herein incorporated by reference in its entirety.
Various examples of cloud-based analytics that are performed by the cloud 104, and are suitable for use with the present disclosure, are described in U.S. Provisional Patent Application Ser. No. 62/611,340, titled CLOUD-BASED MEDICAL ANALYTICS, filed Dec. 28, 2017, the disclosure of which is herein incorporated by reference in its entirety.
In various aspects, the imaging device 124 includes at least one image sensor and one or more optical components. Suitable image sensors include, but are not limited to, Charge-Coupled Device (CCD) sensors and Complementary Metal-Oxide Semiconductor (CMOS) sensors.
The optical components of the imaging device 124 may include one or more illumination sources and/or one or more lenses. The one or more illumination sources may be directed to illuminate portions of the surgical field. The one or more image sensors may receive light reflected or refracted from the surgical field, including light reflected or refracted from tissue and/or surgical instruments.
The one or more illumination sources may be configured to radiate electromagnetic energy in the visible spectrum as well as the invisible spectrum. The visible spectrum, sometimes referred to as the optical spectrum or luminous spectrum, is that portion of the electromagnetic spectrum that is visible to (i.e., can be detected by) the human eye and may be referred to as visible light or simply light. A typical human eye will respond to wavelengths in air that are from about 380 nm to about 750 nm.
The invisible spectrum (i.e., the non-luminous spectrum) is that portion of the electromagnetic spectrum that lies below and above the visible spectrum (i.e., wavelengths below about 380 nm and above about 750 nm). The invisible spectrum is not detectable by the human eye. Wavelengths greater than about 750 nm are longer than the red visible spectrum, and they become invisible infrared (IR), microwave, and radio electromagnetic radiation. Wavelengths less than about 380 nm are shorter than the violet spectrum, and they become invisible ultraviolet, x-ray, and gamma ray electromagnetic radiation.
In various aspects, the imaging device 124 is configured for use in a minimally invasive procedure. Examples of imaging devices suitable for use with the present disclosure include, but not limited to, an arthroscope, angioscope, bronchoscope, choledochoscope, colonoscope, cytoscope, duodenoscope, enteroscope, esophagogastro-duodenoscope (gastroscope), endoscope, laryngoscope, nasopharyngo-neproscope, sigmoidoscope, thoracoscope, and ureteroscope.
In one aspect, the imaging device employs multi-spectrum monitoring to discriminate topography and underlying structures. A multi-spectral image is one that captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, e.g., IR and ultraviolet. Spectral imaging can allow extraction of additional information the human eye fails to capture with its receptors for red, green, and blue. The use of multi-spectral imaging is described in greater detail under the heading “Advanced Imaging Acquisition Module” in U.S. Provisional Patent Application Ser. No. 62/611,341, titled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is herein incorporated by reference in its entirety. Multi-spectrum monitoring can be a useful tool in relocating a surgical field after a surgical task is completed to perform one or more of the previously described tests on the treated tissue.
It is axiomatic that strict sterilization of the operating room and surgical equipment is required during any surgery. The strict hygiene and sterilization conditions required in a “surgical theater,” i.e., an operating or treatment room, necessitate the highest possible sterility of all medical devices and equipment. Part of that sterilization process is the need to sterilize anything that comes in contact with the patient or penetrates the sterile field, including the imaging device 124 and its attachments and components. It will be appreciated that the sterile field may be considered a specified area, such as within a tray or on a sterile towel, that is considered free of microorganisms, or the sterile field may be considered an area, immediately around a patient, who has been prepared for a surgical procedure. The sterile field may include the scrubbed team members, who are properly attired, and all furniture and fixtures in the area.
In various aspects, the visualization system 108 includes one or more imaging sensors, one or more image-processing units, one or more storage arrays, and one or more displays that are strategically arranged with respect to the sterile field, as illustrated in
As illustrated in
In one aspect, the hub 106 is also configured to route a diagnostic input or feedback entered by a non-sterile operator at the visualization tower 111 to the primary display 119 within the sterile field, where it can be viewed by a sterile operator at the operating table. In one example, the input can be in the form of a modification to the snapshot displayed on the non-sterile display 107 or 109, which can be routed to the primary display 119 by the hub 106.

During a surgical procedure, energy application to tissue, for sealing and/or cutting, is generally associated with smoke evacuation, suction of excess fluid, and/or irrigation of the tissue. Fluid, power, and/or data lines from different sources are often entangled during the surgical procedure. Valuable time can be lost addressing this issue during a surgical procedure. Detangling the lines may necessitate disconnecting the lines from their respective modules, which may require resetting the modules. The hub modular enclosure 136 offers a unified environment for managing the power, data, and fluid lines, which reduces the frequency of entanglement between such lines.
Aspects of the present disclosure present a surgical hub for use in a surgical procedure that involves energy application to tissue at a surgical site. The surgical hub includes a hub enclosure and a combo generator module slidably receivable in a docking station of the hub enclosure. The docking station includes data and power contacts. The combo generator module includes two or more of an ultrasonic energy generator component, a bipolar RF energy generator component, and a monopolar RF energy generator component that are housed in a single unit. In one aspect, the combo generator module also includes a smoke evacuation component, at least one energy delivery cable for connecting the combo generator module to a surgical instrument, at least one smoke evacuation component configured to evacuate smoke, fluid, and/or particulates generated by the application of therapeutic energy to the tissue, and a fluid line extending from the remote surgical site to the smoke evacuation component.
In one aspect, the fluid line is a first fluid line and a second fluid line extends from the remote surgical site to a suction and irrigation module slidably received in the hub enclosure. In one aspect, the hub enclosure comprises a fluid interface.
Certain surgical procedures may require the application of more than one energy type to the tissue. One energy type may be more beneficial for cutting the tissue, while another different energy type may be more beneficial for sealing the tissue. For example, a bipolar generator can be used to seal the tissue while an ultrasonic generator can be used to cut the sealed tissue. Aspects of the present disclosure present a solution where a hub modular enclosure 136 is configured to accommodate different generators, and facilitate an interactive communication therebetween. One of the advantages of the hub modular enclosure 136 is enabling the quick removal and/or replacement of various modules.
Aspects of the present disclosure present a modular surgical enclosure for use in a surgical procedure that involves energy application to tissue. The modular surgical enclosure includes a first energy-generator module, configured to generate a first energy for application to the tissue, and a first docking station comprising a first docking port that includes first data and power contacts, wherein the first energy-generator module is slidably movable into an electrical engagement with the power and data contacts and wherein the first energy-generator module is slidably movable out of the electrical engagement with the first power and data contacts,
Further to the above, the modular surgical enclosure also includes a second energy-generator module configured to generate a second energy, different than the first energy, for application to the tissue, and a second docking station comprising a second docking port that includes second data and power contacts, wherein the second energy-generator module is slidably movable into an electrical engagement with the power and data contacts, and wherein the second energy-generator module is slidably movable out of the electrical engagement with the second power and data contacts.
In addition, the modular surgical enclosure also includes a communication bus between the first docking port and the second docking port, configured to facilitate communication between the first energy-generator module and the second energy-generator module.
Referring to
In one aspect, the hub modular enclosure 136 comprises a modular power and communication backplane 149 with external and wireless communication headers to enable the removable attachment of the modules 140, 126, 128 and interactive communication therebetween.
In one aspect, the hub modular enclosure 136 includes docking stations, or drawers, 151, herein also referred to as drawers, which are configured to slidably receive the modules 140, 126, 128.
In various aspects, the smoke evacuation module 126 includes a fluid line 154 that conveys captured/collected smoke and/or fluid away from a surgical site and to, for example, the smoke evacuation module 126. Vacuum suction originating from the smoke evacuation module 126 can draw the smoke into an opening of a utility conduit at the surgical site. The utility conduit, coupled to the fluid line, can be in the form of a flexible tube terminating at the smoke evacuation module 126. The utility conduit and the fluid line define a fluid path extending toward the smoke evacuation module 126 that is received in the hub enclosure 136.
In various aspects, the suction/irrigation module 128 is coupled to a surgical tool comprising an aspiration fluid line and a suction fluid line. In one example, the aspiration and suction fluid lines are in the form of flexible tubes extending from the surgical site toward the suction/irrigation module 128. One or more drive systems can be configured to cause irrigation and aspiration of fluids to and from the surgical site.
In one aspect, the surgical tool includes a shaft having an end effector at a distal end thereof and at least one energy treatment associated with the end effector, an aspiration tube, and an irrigation tube. The aspiration tube can have an inlet port at a distal end thereof and the aspiration tube extends through the shaft. Similarly, an irrigation tube can extend through the shaft and can have an inlet port in proximity to the energy deliver implement. The energy deliver implement is configured to deliver ultrasonic and/or RF energy to the surgical site and is coupled to the generator module 140 by a cable extending initially through the shaft.
The irrigation tube can be in fluid communication with a fluid source, and the aspiration tube can be in fluid communication with a vacuum source. The fluid source and/or the vacuum source can be housed in the suction/irrigation module 128. In one example, the fluid source and/or the vacuum source can be housed in the hub enclosure 136 separately from the suction/irrigation module 128. In such example, a fluid interface can be configured to connect the suction/irrigation module 128 to the fluid source and/or the vacuum source.
In one aspect, the modules 140, 126, 128 and/or their corresponding docking stations on the hub modular enclosure 136 may include alignment features that are configured to align the docking ports of the modules into engagement with their counterparts in the docking stations of the hub modular enclosure 136. For example, as illustrated in
In some aspects, the drawers 151 of the hub modular enclosure 136 are the same, or substantially the same size, and the modules are adjusted in size to be received in the drawers 151. For example, the side brackets 155 and/or 156 can be larger or smaller depending on the size of the module. In other aspects, the drawers 151 are different in size and are each designed to accommodate a particular module.
Furthermore, the contacts of a particular module can be keyed for engagement with the contacts of a particular drawer to avoid inserting a module into a drawer with mismatching contacts.
As illustrated in
In various aspects, the imaging module 138 comprises an integrated video processor and a modular light source and is adapted for use with various imaging devices. In one aspect, the imaging device is comprised of a modular housing that can be assembled with a light source module and a camera module. The housing can be a disposable housing. In at least one example, the disposable housing is removably coupled to a reusable controller, a light source module, and a camera module. The light source module and/or the camera module can be selectively chosen depending on the type of surgical procedure. In one aspect, the camera module comprises a CCD sensor. In another aspect, the camera module comprises a CMOS sensor. In another aspect, the camera module is configured for scanned beam imaging. Likewise, the light source module can be configured to deliver a white light or a different light, depending on the surgical procedure.
During a surgical procedure, removing a surgical device from the surgical field and replacing it with another surgical device that includes a different camera or a different light source can be inefficient. Temporarily losing sight of the surgical field may lead to undesirable consequences. The module imaging device of the present disclosure is configured to permit the replacement of a light source module or a camera module midstream during a surgical procedure, without having to remove the imaging device from the surgical field.
In one aspect, the imaging device comprises a tubular housing that includes a plurality of channels. A first channel is configured to slidably receive the camera module, which can be configured for a snap-fit engagement with the first channel. A second channel is configured to slidably receive the light source module, which can be configured for a snap-fit engagement with the second channel. In another example, the camera module and/or the light source module can be rotated into a final position within their respective channels. A threaded engagement can be employed in lieu of the snap-fit engagement.
In various examples, multiple imaging devices are placed at different positions in the surgical field to provide multiple views. The imaging module 138 can be configured to switch between the imaging devices to provide an optimal view. In various aspects, the imaging module 138 can be configured to integrate the images from the different imaging device.
Various image processors and imaging devices suitable for use with the present disclosure are described in U.S. Pat. No. 7,995,045, titled COMBINED SBI AND CONVENTIONAL IMAGE PROCESSOR, which issued on Aug. 9, 2011, which is herein incorporated by reference in its entirety. In addition, U.S. Pat. No. 7,982,776, titled SBI MOTION ARTIFACT REMOVAL APPARATUS AND METHOD, which issued on Jul. 19, 2011, which is herein incorporated by reference in its entirety, describes various systems for removing motion artifacts from image data. Such systems can be integrated with the imaging module 138. Furthermore, U.S. Patent Application Publication No. 2011/0306840, titled CONTROLLABLE MAGNETIC SOURCE TO FIXTURE INTRACORPOREAL APPARATUS, which published on Dec. 15, 2011, and U.S. Patent Application Publication No. 2014/0243597, titled SYSTEM FOR PERFORMING A MINIMALLY INVASIVE SURGICAL PROCEDURE, which published on Aug. 28, 2014, each of which is herein incorporated by reference in its entirety.
Modular devices 1a-1n located in the operating theater may be coupled to the modular communication hub 203. The network hub 207 and/or the network switch 209 may be coupled to a network router 211 to connect the devices 1a-1n to the cloud 204 or the local computer system 210. Data associated with the devices 1a-1n may be transferred to cloud-based computers via the router for remote data processing and manipulation. Data associated with the devices 1a-1n may also be transferred to the local computer system 210 for local data processing and manipulation. Modular devices 2a-2m located in the same operating theater also may be coupled to a network switch 209. The network switch 209 may be coupled to the network hub 207 and/or the network router 211 to connect to the devices 2a-2m to the cloud 204. Data associated with the devices 2a-2n may be transferred to the cloud 204 via the network router 211 for data processing and manipulation. Data associated with the devices 2a-2m may also be transferred to the local computer system 210 for local data processing and manipulation.
It will be appreciated that the surgical data network 201 may be expanded by interconnecting multiple network hubs 207 and/or multiple network switches 209 with multiple network routers 211. The modular communication hub 203 may be contained in a modular control tower configured to receive multiple devices 1a-1n/2a-2m. The local computer system 210 also may be contained in a modular control tower. The modular communication hub 203 is connected to a display 212 to display images obtained by some of the devices 1a-1n/2a-2m, for example during surgical procedures. In various aspects, the devices 1a-1n/2a-2m may include, for example, various modules such as an imaging module 138 coupled to an endoscope, a generator module 140 coupled to an energy-based surgical device, a smoke evacuation module 126, a suction/irrigation module 128, a communication module 130, a processor module 132, a storage array 134, a surgical device coupled to a display, and/or a non-contact sensor module, among other modular devices that may be connected to the modular communication hub 203 of the surgical data network 201.
In one aspect, the surgical data network 201 may comprise a combination of network hub(s), network switch(es), and network router(s) connecting the devices 1a-1n/2a-2m to the cloud. Any one of or all of the devices 1a-1n/2a-2m coupled to the network hub or network switch may collect data in real time and transfer the data to cloud computers for data processing and manipulation. It will be appreciated that cloud computing relies on sharing computing resources rather than having local servers or personal devices to handle software applications. The word “cloud” may be used as a metaphor for “the Internet,” although the term is not limited as such. Accordingly, the term “cloud computing” may be used herein to refer to “a type of Internet-based computing,” where different services—such as servers, storage, and applications—are delivered to the modular communication hub 203 and/or computer system 210 located in the surgical theater (e.g., a fixed, mobile, temporary, or field operating room or space) and to devices connected to the modular communication hub 203 and/or computer system 210 through the Internet. The cloud infrastructure may be maintained by a cloud service provider. In this context, the cloud service provider may be the entity that coordinates the usage and control of the devices 1a-1n/2a-2m located in one or more operating theaters. The cloud computing services can perform a large number of calculations based on the data gathered by smart surgical instruments, robots, and other computerized devices located in the operating theater. The hub hardware enables multiple devices or connections to be connected to a computer that communicates with the cloud computing resources and storage.
Applying cloud computer data processing techniques on the data collected by the devices 1a-1n/2a-2m, the surgical data network provides improved surgical outcomes, reduced costs, and improved patient satisfaction. At least some of the devices 1a-1n/2a-2m may be employed to view tissue states to assess leaks or perfusion of sealed tissue after a tissue sealing and cutting procedure. At least some of the devices 1a-1n/2a-2m may be employed to identify pathology, such as the effects of diseases, using the cloud-based computing to examine data including images of samples of body tissue for diagnostic purposes. This includes localization and margin confirmation of tissue and phenotypes. At least some of the devices 1a-1n/2a-2m may be employed to identify anatomical structures of the body using a variety of sensors integrated with imaging devices and techniques such as overlaying images captured by multiple imaging devices. The data gathered by the devices 1a-1n/2a-2m, including image data, may be transferred to the cloud 204 or the local computer system 210 or both for data processing and manipulation including image processing and manipulation. The data may be analyzed to improve surgical procedure outcomes by determining if further treatment, such as the application of endoscopic intervention, emerging technologies, a targeted radiation, targeted intervention, and precise robotics to tissue-specific sites and conditions, may be pursued. Such data analysis may further employ outcome analytics processing, and using standardized approaches may provide beneficial feedback to either confirm surgical treatments and the behavior of the surgeon or suggest modifications to surgical treatments and the behavior of the surgeon.
In one implementation, the operating theater devices 1a-1n may be connected to the modular communication hub 203 over a wired channel or a wireless channel depending on the configuration of the devices 1a-1n to a network hub. The network hub 207 may be implemented, in one aspect, as a local network broadcast device that works on the physical layer of the Open System Interconnection (OSI) model. The network hub provides connectivity to the devices 1a-1n located in the same operating theater network. The network hub 207 collects data in the form of packets and sends them to the router in half duplex mode. The network hub 207 does not store any media access control/Internet Protocol (MAC/IP) to transfer the device data. Only one of the devices 1a-1n can send data at a time through the network hub 207. The network hub 207 has no routing tables or intelligence regarding where to send information and broadcasts all network data across each connection and to a remote server 213 (
In another implementation, the operating theater devices 2a-2m may be connected to a network switch 209 over a wired channel or a wireless channel. The network switch 209 works in the data link layer of the OSI model. The network switch 209 is a multicast device for connecting the devices 2a-2m located in the same operating theater to the network. The network switch 209 sends data in the form of frames to the network router 211 and works in full duplex mode. Multiple devices 2a-2m can send data at the same time through the network switch 209. The network switch 209 stores and uses MAC addresses of the devices 2a-2m to transfer data.
The network hub 207 and/or the network switch 209 are coupled to the network router 211 for connection to the cloud 204. The network router 211 works in the network layer of the OSI model. The network router 211 creates a route for transmitting data packets received from the network hub 207 and/or network switch 211 to cloud-based computer resources for further processing and manipulation of the data collected by any one of or all the devices 1a-1n/2a-2m. The network router 211 may be employed to connect two or more different networks located in different locations, such as, for example, different operating theaters of the same healthcare facility or different networks located in different operating theaters of different healthcare facilities. The network router 211 sends data in the form of packets to the cloud 204 and works in full duplex mode. Multiple devices can send data at the same time. The network router 211 uses IP addresses to transfer data.
In one example, the network hub 207 may be implemented as a USB hub, which allows multiple USB devices to be connected to a host computer. The USB hub may expand a single USB port into several tiers so that there are more ports available to connect devices to the host system computer. The network hub 207 may include wired or wireless capabilities to receive information over a wired channel or a wireless channel. In one aspect, a wireless USB short-range, high-bandwidth wireless radio communication protocol may be employed for communication between the devices 1a-1n and devices 2a-2m located in the operating theater.
In other examples, the operating theater devices 1a-1n/2a-2m may communicate to the modular communication hub 203 via Bluetooth wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). In other aspects, the operating theater devices 1a-1n/2a-2m may communicate to the modular communication hub 203 via a number of wireless or wired communication standards or protocols, including but not limited to Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20, long-term evolution (LTE), and Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, DECT, and Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. The computing module may include a plurality of communication modules. For instance, a first communication module may be dedicated to shorter-range wireless communications such as Wi-Fi and Bluetooth, and a second communication module may be dedicated to longer-range wireless communications such as GPS, EDGE, GPRS, CDMA, WiMAX, LTE, Ev-DO, and others.
The modular communication hub 203 may serve as a central connection for one or all of the operating theater devices 1a-1n/2a-2m and handles a data type known as frames. Frames carry the data generated by the devices 1a-1n/2a-2m. When a frame is received by the modular communication hub 203, it is amplified and transmitted to the network router 211, which transfers the data to the cloud computing resources by using a number of wireless or wired communication standards or protocols, as described herein.
The modular communication hub 203 can be used as a standalone device or be connected to compatible network hubs and network switches to form a larger network. The modular communication hub 203 is generally easy to install, configure, and maintain, making it a good option for networking the operating theater devices 1a-1n/2a-2m.
The surgical hub 206 employs a non-contact sensor module 242 to measure the dimensions of the operating theater and generate a map of the surgical theater using either ultrasonic or laser-type non-contact measurement devices. An ultrasound-based non-contact sensor module scans the operating theater by transmitting a burst of ultrasound and receiving the echo when it bounces off the perimeter walls of an operating theater as described under the heading “Surgical Hub Spatial Awareness Within an Operating Room” in U.S. Provisional Patent Application Ser. No. 62/611,341, titled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, which is herein incorporated by reference in its entirety, in which the sensor module is configured to determine the size of the operating theater and to adjust Bluetooth-pairing distance limits. A laser-based non-contact sensor module scans the operating theater by transmitting laser light pulses, receiving laser light pulses that bounce off the perimeter walls of the operating theater, and comparing the phase of the transmitted pulse to the received pulse to determine the size of the operating theater and to adjust Bluetooth pairing distance limits, for example.
The computer system 210 comprises a processor 244 and a network interface 245. The processor 244 is coupled to a communication module 247, storage 248, memory 249, non-volatile memory 250, and input/output interface 251 via a system bus.

The system memory includes volatile memory and non-volatile memory. The basic input/output system (BIOS), containing the basic routines to transfer information between elements within the computer system, such as during start-up, is stored in non-volatile memory. For example, the non-volatile memory can include ROM, programmable ROM (PROM), electrically programmable ROM (EPROM), EEPROM, or flash memory. Volatile memory includes random-access memory (RAM), which acts as external cache memory. Moreover, RAM is available in many forms such as SRAM, dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM).

To facilitate the connection of the disk storage devices to the system bus, a removable or non-removable interface may be employed.
It is to be appreciated that the computer system 210 includes software that acts as an intermediary between users and the basic computer resources described in a suitable operating environment. Such software includes an operating system. The operating system, which can be stored on the disk storage, acts to control and allocate resources of the computer system. System applications take advantage of the management of resources by the operating system through program modules and program data stored either in the system memory or on the disk storage. It is to be appreciated that various components described herein can be implemented with various operating systems or combinations of operating systems.
A user enters commands or information into the computer system 210 through input device(s) coupled to the I/O interface 251. The input devices include, but are not limited to, a pointing device such as a mouse, trackball, stylus, touch pad, keyboard, microphone, joystick, game pad, satellite dish, scanner, TV tuner card, digital camera, digital video camera, web camera, and the like. These and other input devices connect to the processor through the system bus via interface port(s). The interface port(s) include, for example, a serial port, a parallel port, a game port, and a USB. The output device(s) use some of the same types of ports as input device(s). Thus, for example, a USB port may be used to provide input to the computer system and to output information from the computer system to an output device. An output adapter is provided to illustrate that there are some output devices like monitors, displays, speakers, and printers, among other output devices that require special adapters. The output adapters include, by way of illustration and not limitation, video and sound cards that provide a means of connection between the output device and the system bus. It should be noted that other devices and/or systems of devices, such as remote computer(s), provide both input and output capabilities.
The computer system 210 can operate in a networked environment using logical connections to one or more remote computers, such as cloud computer(s), or local computers.

The USB network hub 300 device is implemented with a digital state machine instead of a microcontroller, and no firmware programming is required. Fully compliant USB transceivers are integrated into the circuit for the upstream USB transceiver port 302 and all downstream USB transceiver ports 304, 306, 308. The downstream USB transceiver ports 304, 306, 308 support both full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The USB network hub 300 device may be configured either in bus-powered or self-powered mode and includes a hub power logic 312 to manage power.
The USB network hub 300 device includes a serial interface engine 310 (SIE). The SIE 310 is the front end of the USB network hub 300 hardware and handles most of the protocol described in chapter 8 of the USB specification. The SIE 310 typically comprehends signaling up to the transaction level. The functions that it handles could include: packet recognition, transaction sequencing, SOP, EOP, RESET, and RESUME signal detection/generation, clock/data separation, non-return-to-zero invert (NRZI) data encoding/decoding and bit-stuffing, CRC generation and checking (token and data), packet ID (PID) generation and checking/decoding, and/or serial-parallel/parallel-serial conversion. The 310 receives a clock input 314 and is coupled to a suspend/resume logic and frame timer 316 circuit and a hub repeater circuit 318 to control communication between the upstream USB transceiver port 302 and the downstream USB transceiver ports 304, 306, 308 through port logic circuits 320, 322, 324. The SIE 310 is coupled to a command decoder 326 via interface logic 328 to control commands from a serial EEPROM via a serial EEPROM interface 330.
In various aspects, the USB network hub 300 can connect 127 functions configured in up to six logical layers (tiers) to a single computer. Further, the USB network hub 300 can connect to all peripherals using a standardized four-wire cable that provides both communication and power distribution. The power configurations are bus-powered and self-powered modes. The USB network hub 300 may be configured to support four modes of power management: a bus-powered hub, with either individual-port power management or ganged-port power management, and the self-powered hub, with either individual-port power management or ganged-port power management. In one aspect, using a USB cable, the USB network hub 300, the upstream USB transceiver port 302 is plugged into a USB host controller, and the downstream USB transceiver ports 304, 306, 308 are exposed for connecting USB compatible devices, and so forth.
Additional details regarding the structure and function of the surgical hub and/or surgical hub networks can be found in U.S. Provisional Patent Application No. 62/659,900, titled METHOD OF HUB COMMUNICATION, filed Apr. 19, 2018, which is hereby incorporated by reference herein in its entirety.
In addition, surgical instruments 7012 may comprise transceivers for data transmission to and from their corresponding surgical hubs 7006 (which may also comprise transceivers). Combinations of surgical instruments 7012 and corresponding hubs 7006 may indicate particular locations, such as operating theaters in healthcare facilities (e.g., hospitals), for providing medical operations. For example, the memory of a surgical hub 7006 may store location data. As shown in
Based on connections to various surgical hubs 7006 via the network 7001, the cloud 7004 can aggregate data from specific data generated by various surgical instruments 7012 and their corresponding hubs 7006. Such aggregated data may be stored within the aggregated medical databases 7011 of the cloud 7004. In particular, the cloud 7004 may advantageously perform data analysis and operations on the aggregated data to yield insights and/or perform functions that individual hubs 7006 could not achieve on their own. To this end, as shown in
The particular cloud computing system configuration described in the present disclosure is specifically designed to address various issues arising in the context of medical operations and procedures performed using medical devices, such as the surgical instruments 7012, 112. In particular, the surgical instruments 7012 may be digital surgical devices configured to interact with the cloud 7004 for implementing techniques to improve the performance of surgical operations. Various surgical instruments 7012 and/or surgical hubs 7006 may comprise touch controlled user interfaces such that clinicians may control aspects of interaction between the surgical instruments 7012 and the cloud 7004. Other suitable user interfaces for control such as auditory controlled user interfaces can also be used.
For example, the data collection and aggregation module 7022 could be used to generate self-describing data (e.g., metadata) including identification of notable features or configuration (e.g., trends), management of redundant data sets, and storage of the data in paired data sets which can be grouped by surgery but not necessarily keyed to actual surgical dates and surgeons. In particular, pair data sets generated from operations of surgical instruments 7012 can comprise applying a binary classification, e.g., a bleeding or a non-bleeding event. More generally, the binary classification may be characterized as either a desirable event (e.g., a successful surgical procedure) or an undesirable event (e.g., a misfired or misused surgical instrument 7012). The aggregated self-describing data may correspond to individual data received from various groups or subgroups of surgical hubs 7006. Accordingly, the data collection and aggregation module 7022 can generate aggregated metadata or other organized data based on raw data received from the surgical hubs 7006. To this end, the processors 7008 can be operationally coupled to the hub applications 7014 and aggregated medical data databases 7011 for executing the data analytics modules 7034. The data collection and aggregation module 7022 may store the aggregated organized data into the aggregated medical data databases 2212.
The resource optimization module 7020 can be configured to analyze this aggregated data to determine an optimal usage of resources for a particular or group of healthcare facilities. For example, the resource optimization module 7020 may determine an optimal order point of surgical stapling instruments 7012 for a group of healthcare facilities based on corresponding predicted demand of such instruments 7012. The resource optimization module 7020 might also assess the resource usage or other operational configurations of various healthcare facilities to determine whether resource usage could be improved. Similarly, the recommendations module 7030 can be configured to analyze aggregated organized data from the data collection and aggregation module 7022 to provide recommendations. For example, the recommendations module 7030 could recommend to healthcare facilities (e.g., medical service providers such as hospitals) that a particular surgical instrument 7012 should be upgraded to an improved version based on a higher than expected error rate, for example. Additionally, the recommendations module 7030 and/or resource optimization module 7020 could recommend better supply chain parameters such as product reorder points and provide suggestions of different surgical instrument 7012, uses thereof, or procedure steps to improve surgical outcomes. The healthcare facilities can receive such recommendations via corresponding surgical hubs 7006. More specific recommendations regarding parameters or configurations of various surgical instruments 7012 can also be provided. Hubs 7006 and/or surgical instruments 7012 each could also have display screens that display data or recommendations provided by the cloud 7004.
The patient outcome analysis module 7028 can analyze surgical outcomes associated with currently used operational parameters of surgical instruments 7012. The patient outcome analysis module 7028 may also analyze and assess other potential operational parameters. In this connection, the recommendations module 7030 could recommend using these other potential operational parameters based on yielding better surgical outcomes, such as better sealing or less bleeding. For example, the recommendations module 7030 could transmit recommendations to a surgical hub 7006 regarding when to use a particular cartridge for a corresponding stapling surgical instrument 7012. Thus, the cloud-based analytics system, while controlling for common variables, may be configured to analyze the large collection of raw data and to provide centralized recommendations over multiple healthcare facilities (advantageously determined based on aggregated data). For example, the cloud-based analytics system could analyze, evaluate, and/or aggregate data based on type of medical practice, type of patient, number of patients, geographic similarity between medical providers, which medical providers/facilities use similar types of instruments, etc., in a way that no single healthcare facility alone would be able to analyze independently.
The control program updating module 7026 could be configured to implement various surgical instrument 7012 recommendations when corresponding control programs are updated. For example, the patient outcome analysis module 7028 could identify correlations linking specific control parameters with successful (or unsuccessful) results. Such correlations may be addressed when updated control programs are transmitted to surgical instruments 7012 via the control program updating module 7026. Updates to instruments 7012 that are transmitted via a corresponding hub 7006 may incorporate aggregated performance data that was gathered and analyzed by the data collection and aggregation module 7022 of the cloud 7004. Additionally, the patient outcome analysis module 7028 and recommendations module 7030 could identify improved methods of using instruments 7012 based on aggregated performance data.
The cloud-based analytics system may include security features implemented by the cloud 7004. These security features may be managed by the authorization and security module 7024. Each surgical hub 7006 can have associated unique credentials such as username, password, and other suitable security credentials. These credentials could be stored in the memory 7010 and be associated with a permitted cloud access level. For example, based on providing accurate credentials, a surgical hub 7006 may be granted access to communicate with the cloud to a predetermined extent (e.g., may only engage in transmitting or receiving certain defined types of information). To this end, the aggregated medical data databases 7011 of the cloud 7004 may comprise a database of authorized credentials for verifying the accuracy of provided credentials. Different credentials may be associated with varying levels of permission for interaction with the cloud 7004, such as a predetermined access level for receiving the data analytics generated by the cloud 7004.
Furthermore, for security purposes, the cloud could maintain a database of hubs 7006, instruments 7012, and other devices that may comprise a “black list” of prohibited devices. In particular, a surgical hub 7006 listed on the black list may not be permitted to interact with the cloud, while surgical instruments 7012 listed on the black list may not have functional access to a corresponding hub 7006 and/or may be prevented from fully functioning when paired to its corresponding hub 7006. Additionally or alternatively, the cloud 7004 may flag instruments 7012 based on incompatibility or other specified criteria. In this manner, counterfeit medical devices and improper reuse of such devices throughout the cloud-based analytics system can be identified and addressed.
The surgical instruments 7012 may use wireless transceivers to transmit wireless signals that may represent, for example, authorization credentials for access to corresponding hubs 7006 and the cloud 7004. Wired transceivers may also be used to transmit signals. Such authorization credentials can be stored in the respective memory devices of the surgical instruments 7012. The authorization and security module 7024 can determine whether the authorization credentials are accurate or counterfeit. The authorization and security module 7024 may also dynamically generate authorization credentials for enhanced security. The credentials could also be encrypted, such as by using hash based encryption. Upon transmitting proper authorization, the surgical instruments 7012 may transmit a signal to the corresponding hubs 7006 and ultimately the cloud 7004 to indicate that the instruments 7012 are ready to obtain and transmit medical data. In response, the cloud 7004 may transition into a state enabled for receiving medical data for storage into the aggregated medical data databases 7011. This data transmission readiness could be indicated by a light indicator on the instruments 7012, for example. The cloud 7004 can also transmit signals to surgical instruments 7012 for updating their associated control programs. The cloud 7004 can transmit signals that are directed to a particular class of surgical instruments 7012 (e.g., electrosurgical instruments) so that software updates to control programs are only transmitted to the appropriate surgical instruments 7012. Moreover, the cloud 7004 could be used to implement system wide solutions to address local or global problems based on selective data transmission and authorization credentials. For example, if a group of surgical instruments 7012 are identified as having a common manufacturing defect, the cloud 7004 may change the authorization credentials corresponding to this group to implement an operational lockout of the group.
The cloud-based analytics system may allow for monitoring multiple healthcare facilities (e.g., medical facilities like hospitals) to determine improved practices and recommend changes (via the recommendations module 2030, for example) accordingly. Thus, the processors 7008 of the cloud 7004 can analyze data associated with an individual healthcare facility to identify the facility and aggregate the data with other data associated with other healthcare facilities in a group. Groups could be defined based on similar operating practices or geographical location, for example. In this way, the cloud 7004 may provide healthcare facility group wide analysis and recommendations. The cloud-based analytics system could also be used for enhanced situational awareness. For example, the processors 7008 may predictively model the effects of recommendations on the cost and effectiveness for a particular facility (relative to overall operations and/or various medical procedures). The cost and effectiveness associated with that particular facility can also be compared to a corresponding local region of other facilities or any other comparable facilities.
The data sorting and prioritization module 7032 may prioritize and sort data based on criticality (e.g., the severity of a medical event associated with the data, unexpectedness, suspiciousness). This sorting and prioritization may be used in conjunction with the functions of the other data analytics modules 7034 described above to improve the cloud-based analytics and operations described herein. For example, the data sorting and prioritization module 7032 can assign a priority to the data analysis performed by the data collection and aggregation module 7022 and patient outcome analysis modules 7028. Different prioritization levels can result in particular responses from the cloud 7004 (corresponding to a level of urgency) such as escalation for an expedited response, special processing, exclusion from the aggregated medical data databases 7011, or other suitable responses. Moreover, if necessary, the cloud 7004 can transmit a request (e.g. a push message) through the hub application servers for additional data from corresponding surgical instruments 7012. The push message can result in a notification displayed on the corresponding hubs 7006 for requesting supporting or additional data. This push message may be required in situations in which the cloud detects a significant irregularity or outlier and the cloud cannot determine the cause of the irregularity. The central servers 7013 may be programmed to trigger this push message in certain significant circumstances, such as when data is determined to be different from an expected value beyond a predetermined threshold or when it appears security has been comprised, for example.
Additional details regarding the cloud analysis system can be found in U.S. Provisional Patent Application No. 62/659,900, titled METHOD OF HUB COMMUNICATION, filed Apr. 19, 2018, which is hereby incorporated by reference herein in its entirety.
Although an “intelligent” device including control algorithms that respond to sensed data can be an improvement over a “dumb” device that operates without accounting for sensed data, some sensed data can be incomplete or inconclusive when considered in isolation, i.e., without the context of the type of surgical procedure being performed or the type of tissue that is being operated on. Without knowing the procedural context (e.g., knowing the type of tissue being operated on or the type of procedure being performed), the control algorithm may control the modular device incorrectly or suboptimally given the particular context-free sensed data. For example, the optimal manner for a control algorithm to control a surgical instrument in response to a particular sensed parameter can vary according to the particular tissue type being operated on. This is due to the fact that different tissue types have different properties (e.g., resistance to tearing) and thus respond differently to actions taken by surgical instruments. Therefore, it may be desirable for a surgical instrument to take different actions even when the same measurement for a particular parameter is sensed. As one specific example, the optimal manner in which to control a surgical stapling and cutting instrument in response to the instrument sensing an unexpectedly high force to close its end effector will vary depending upon whether the tissue type is susceptible or resistant to tearing. For tissues that are susceptible to tearing, such as lung tissue, the instrument's control algorithm would optimally ramp down the motor in response to an unexpectedly high force to close to avoid tearing the tissue. For tissues that are resistant to tearing, such as stomach tissue, the instrument's control algorithm would optimally ramp up the motor in response to an unexpectedly high force to close to ensure that the end effector is clamped properly on the tissue. Without knowing whether lung or stomach tissue has been clamped, the control algorithm may make a suboptimal decision.
One solution utilizes a surgical hub including a system that is configured to derive information about the surgical procedure being performed based on data received from various data sources and then control the paired modular devices accordingly. In other words, the surgical hub is configured to infer information about the surgical procedure from received data and then control the modular devices paired to the surgical hub based upon the inferred context of the surgical procedure.
A surgical hub 5104, which may be similar to the hub 106 in many respects, can be configured to derive the contextual information pertaining to the surgical procedure from the data based upon, for example, the particular combination(s) of received data or the particular order in which the data is received from the data sources 5126. The contextual information inferred from the received data can include, for example, the type of surgical procedure being performed, the particular step of the surgical procedure that the surgeon is performing, the type of tissue being operated on, or the body cavity that is the subject of the procedure. This ability by some aspects of the surgical hub 5104 to derive or infer information related to the surgical procedure from received data can be referred to as “situational awareness.” In one exemplification, the surgical hub 5104 can incorporate a situational awareness system, which is the hardware and/or programming associated with the surgical hub 5104 that derives contextual information pertaining to the surgical procedure from the received data.
The situational awareness system of the surgical hub 5104 can be configured to derive the contextual information from the data received from the data sources 5126 in a variety of different ways. In one exemplification, the situational awareness system includes a pattern recognition system, or machine learning system (e.g., an artificial neural network), that has been trained on training data to correlate various inputs (e.g., data from databases 5122, patient monitoring devices 5124, and/or modular devices 5102) to corresponding contextual information regarding a surgical procedure. In other words, a machine learning system can be trained to accurately derive contextual information regarding a surgical procedure from the provided inputs. In another exemplification, the situational awareness system can include a lookup table storing pre-characterized contextual information regarding a surgical procedure in association with one or more inputs (or ranges of inputs) corresponding to the contextual information. In response to a query with one or more inputs, the lookup table can return the corresponding contextual information for the situational awareness system for controlling the modular devices 5102. In one exemplification, the contextual information received by the situational awareness system of the surgical hub 5104 is associated with a particular control adjustment or set of control adjustments for one or more modular devices 5102. In another exemplification, the situational awareness system includes a further machine learning system, lookup table, or other such system, which generates or retrieves one or more control adjustments for one or more modular devices 5102 when provided the contextual information as input.
A surgical hub 5104 incorporating a situational awareness system provides a number of benefits for the surgical system 5100. One benefit includes improving the interpretation of sensed and collected data, which would in turn improve the processing accuracy and/or the usage of the data during the course of a surgical procedure. To return to a previous example, a situationally aware surgical hub 5104 could determine what type of tissue was being operated on; therefore, when an unexpectedly high force to close the surgical instrument's end effector is detected, the situationally aware surgical hub 5104 could correctly ramp up or ramp down the motor of the surgical instrument for the type of tissue.
As another example, the type of tissue being operated can affect the adjustments that are made to the compression rate and load thresholds of a surgical stapling and cutting instrument for a particular tissue gap measurement. A situationally aware surgical hub 5104 could infer whether a surgical procedure being performed is a thoracic or an abdominal procedure, allowing the surgical hub 5104 to determine whether the tissue clamped by an end effector of the surgical stapling and cutting instrument is lung (for a thoracic procedure) or stomach (for an abdominal procedure) tissue. The surgical hub 5104 could then adjust the compression rate and load thresholds of the surgical stapling and cutting instrument appropriately for the type of tissue.
As yet another example, the type of body cavity being operated in during an insufflation procedure can affect the function of a smoke evacuator. A situationally aware surgical hub 5104 could determine whether the surgical site is under pressure (by determining that the surgical procedure is utilizing insufflation) and determine the procedure type. As a procedure type is generally performed in a specific body cavity, the surgical hub 5104 could then control the motor rate of the smoke evacuator appropriately for the body cavity being operated in. Thus, a situationally aware surgical hub 5104 could provide a consistent amount of smoke evacuation for both thoracic and abdominal procedures.
As yet another example, the type of procedure being performed can affect the optimal energy level for an ultrasonic surgical instrument or radio frequency (RF) electrosurgical instrument to operate at. Arthroscopic procedures, for example, require higher energy levels because the end effector of the ultrasonic surgical instrument or RF electrosurgical instrument is immersed in fluid. A situationally aware surgical hub 5104 could determine whether the surgical procedure is an arthroscopic procedure. The surgical hub 5104 could then adjust the RF power level or the ultrasonic amplitude of the generator (i.e., “energy level”) to compensate for the fluid filled environment. Relatedly, the type of tissue being operated on can affect the optimal energy level for an ultrasonic surgical instrument or RF electrosurgical instrument to operate at. A situationally aware surgical hub 5104 could determine what type of surgical procedure is being performed and then customize the energy level for the ultrasonic surgical instrument or RF electrosurgical instrument, respectively, according to the expected tissue profile for the surgical procedure. Furthermore, a situationally aware surgical hub 5104 can be configured to adjust the energy level for the ultrasonic surgical instrument or RF electrosurgical instrument throughout the course of a surgical procedure, rather than just on a procedure-by-procedure basis. A situationally aware surgical hub 5104 could determine what step of the surgical procedure is being performed or will subsequently be performed and then update the control algorithms for the generator and/or ultrasonic surgical instrument or RF electrosurgical instrument to set the energy level at a value appropriate for the expected tissue type according to the surgical procedure step.
As yet another example, data can be drawn from additional data sources 5126 to improve the conclusions that the surgical hub 5104 draws from one data source 5126. A situationally aware surgical hub 5104 could augment data that it receives from the modular devices 5102 with contextual information that it has built up regarding the surgical procedure from other data sources 5126. For example, a situationally aware surgical hub 5104 can be configured to determine whether hemostasis has occurred (i.e., whether bleeding at a surgical site has stopped) according to video or image data received from a medical imaging device. However, in some cases the video or image data can be inconclusive. Therefore, in one exemplification, the surgical hub 5104 can be further configured to compare a physiologic measurement (e.g., blood pressure sensed by a BP monitor communicably connected to the surgical hub 5104) with the visual or image data of hemostasis (e.g., from a medical imaging device 124 (
Another benefit includes proactively and automatically controlling the paired modular devices 5102 according to the particular step of the surgical procedure that is being performed to reduce the number of times that medical personnel are required to interact with or control the surgical system 5100 during the course of a surgical procedure. For example, a situationally aware surgical hub 5104 could proactively activate the generator to which an RF electrosurgical instrument is connected if it determines that a subsequent step of the procedure requires the use of the instrument. Proactively activating the energy source allows the instrument to be ready for use a soon as the preceding step of the procedure is completed.
As another example, a situationally aware surgical hub 5104 could determine whether the current or subsequent step of the surgical procedure requires a different view or degree of magnification on the display according to the feature(s) at the surgical site that the surgeon is expected to need to view. The surgical hub 5104 could then proactively change the displayed view (supplied by, e.g., a medical imaging device for the visualization system 108) accordingly so that the display automatically adjusts throughout the surgical procedure.
As yet another example, a situationally aware surgical hub 5104 could determine which step of the surgical procedure is being performed or will subsequently be performed and whether particular data or comparisons between data will be required for that step of the surgical procedure. The surgical hub 5104 can be configured to automatically call up data screens based upon the step of the surgical procedure being performed, without waiting for the surgeon to ask for the particular information.
Another benefit includes checking for errors during the setup of the surgical procedure or during the course of the surgical procedure. For example, a situationally aware surgical hub 5104 could determine whether the operating theater is setup properly or optimally for the surgical procedure to be performed. The surgical hub 5104 can be configured to determine the type of surgical procedure being performed, retrieve the corresponding checklists, product location, or setup needs (e.g., from a memory), and then compare the current operating theater layout to the standard layout for the type of surgical procedure that the surgical hub 5104 determines is being performed. In one exemplification, the surgical hub 5104 can be configured to compare the list of items for the procedure scanned by a suitable scanner for example, and/or a list of devices paired with the surgical hub 5104 to a recommended or anticipated manifest of items and/or devices for the given surgical procedure. If there are any discontinuities between the lists, the surgical hub 5104 can be configured to provide an alert indicating that a particular modular device 5102, patient monitoring device 5124, and/or other surgical item is missing. In one exemplification, the surgical hub 5104 can be configured to determine the relative distance or position of the modular devices 5102 and patient monitoring devices 5124 via proximity sensors, for example. The surgical hub 5104 can compare the relative positions of the devices to a recommended or anticipated layout for the particular surgical procedure. If there are any discontinuities between the layouts, the surgical hub 5104 can be configured to provide an alert indicating that the current layout for the surgical procedure deviates from the recommended layout.
As another example, a situationally aware surgical hub 5104 could determine whether the surgeon (or other medical personnel) was making an error or otherwise deviating from the expected course of action during the course of a surgical procedure. For example, the surgical hub 5104 can be configured to determine the type of surgical procedure being performed, retrieve the corresponding list of steps or order of equipment usage (e.g., from a memory), and then compare the steps being performed or the equipment being used during the course of the surgical procedure to the expected steps or equipment for the type of surgical procedure that the surgical hub 5104 determined is being performed. In one exemplification, the surgical hub 5104 can be configured to provide an alert indicating that an unexpected action is being performed or an unexpected device is being utilized at the particular step in the surgical procedure.
Overall, the situational awareness system for the surgical hub 5104 improves surgical procedure outcomes by adjusting the surgical instruments (and other modular devices 5102) for the particular context of each surgical procedure (such as adjusting to different tissue types) and validating actions during a surgical procedure. The situational awareness system also improves surgeons' efficiency in performing surgical procedures by automatically suggesting next steps, providing data, and adjusting displays and other modular devices 5102 in the surgical theater according to the specific context of the procedure.
Referring now to
The situationally aware surgical hub 106, 206 receives data from the data sources throughout the course of the surgical procedure, including data generated each time medical personnel utilize a modular device that is paired with the surgical hub 106, 206. The surgical hub 106, 206 can receive this data from the paired modular devices and other data sources and continually derive inferences (i.e., contextual information) about the ongoing procedure as new data is received, such as which step of the procedure is being performed at any given time. The situational awareness system of the surgical hub 106, 206 is able to, for example, record data pertaining to the procedure for generating reports, verify the steps being taken by the medical personnel, provide data or prompts (e.g., via a display screen) that may be pertinent for the particular procedural step, adjust modular devices based on the context (e.g., activate monitors, adjust the field of view (FOV) of the medical imaging device, or change the energy level of an ultrasonic surgical instrument or RF electrosurgical instrument), and take any other such action described above.
As the first step 5202 in this illustrative procedure, the hospital staff members retrieve the patient's EMR from the hospital's EMR database. Based on select patient data in the EMR, the surgical hub 106, 206 determines that the procedure to be performed is a thoracic procedure.
Second step 5204, the staff members scan the incoming medical supplies for the procedure. The surgical hub 106, 206 cross-references the scanned supplies with a list of supplies that are utilized in various types of procedures and confirms that the mix of supplies corresponds to a thoracic procedure. Further, the surgical hub 106, 206 is also able to determine that the procedure is not a wedge procedure (because the incoming supplies either lack certain supplies that are necessary for a thoracic wedge procedure or do not otherwise correspond to a thoracic wedge procedure).
Third step 5206, the medical personnel scan the patient band via a scanner that is communicably connected to the surgical hub 106, 206. The surgical hub 106, 206 can then confirm the patient's identity based on the scanned data.
Fourth step 5208, the medical staff turns on the auxiliary equipment. The auxiliary equipment being utilized can vary according to the type of surgical procedure and the techniques to be used by the surgeon, but in this illustrative case they include a smoke evacuator, insufflator, and medical imaging device. When activated, the auxiliary equipment that are modular devices can automatically pair with the surgical hub 106, 206 that is located within a particular vicinity of the modular devices as part of their initialization process. The surgical hub 106, 206 can then derive contextual information about the surgical procedure by detecting the types of modular devices that pair with it during this pre-operative or initialization phase. In this particular example, the surgical hub 106, 206 determines that the surgical procedure is a VATS procedure based on this particular combination of paired modular devices. Based on the combination of the data from the patient's EMR, the list of medical supplies to be used in the procedure, and the type of modular devices that connect to the hub, the surgical hub 106, 206 can generally infer the specific procedure that the surgical team will be performing. Once the surgical hub 106, 206 knows what specific procedure is being performed, the surgical hub 106, 206 can then retrieve the steps of that procedure from a memory or from the cloud and then cross-reference the data it subsequently receives from the connected data sources (e.g., modular devices and patient monitoring devices) to infer what step of the surgical procedure the surgical team is performing.
Fifth step 5210, the staff members attach the EKG electrodes and other patient monitoring devices to the patient. The EKG electrodes and other patient monitoring devices are able to pair with the surgical hub 106, 206. As the surgical hub 106, 206 begins receiving data from the patient monitoring devices, the surgical hub 106, 206 thus confirms that the patient is in the operating theater.
Sixth step 5212, the medical personnel induce anesthesia in the patient. The surgical hub 106, 206 can infer that the patient is under anesthesia based on data from the modular devices and/or patient monitoring devices, including EKG data, blood pressure data, ventilator data, or combinations thereof, for example. Upon completion of the sixth step 5212, the pre-operative portion of the lung segmentectomy procedure is completed and the operative portion begins.
Seventh step 5214, the patient's lung that is being operated on is collapsed (while ventilation is switched to the contralateral lung). The surgical hub 106, 206 can infer from the ventilator data that the patient's lung has been collapsed, for example. The surgical hub 106, 206 can infer that the operative portion of the procedure has commenced as it can compare the detection of the patient's lung collapsing to the expected steps of the procedure (which can be accessed or retrieved previously) and thereby determine that collapsing the lung is the first operative step in this particular procedure.
Eighth step 5216, the medical imaging device (e.g., a scope) is inserted and video from the medical imaging device is initiated. The surgical hub 106, 206 receives the medical imaging device data (i.e., video or image data) through its connection to the medical imaging device. Upon receipt of the medical imaging device data, the surgical hub 106, 206 can determine that the laparoscopic portion of the surgical procedure has commenced. Further, the surgical hub 106, 206 can determine that the particular procedure being performed is a segmentectomy, as opposed to a lobectomy (note that a wedge procedure has already been discounted by the surgical hub 106, 206 based on data received at the second step 5204 of the procedure). The data from the medical imaging device 124 (
Ninth step 5218, the surgical team begins the dissection step of the procedure. The surgical hub 106, 206 can infer that the surgeon is in the process of dissecting to mobilize the patient's lung because it receives data from the RF or ultrasonic generator indicating that an energy instrument is being fired. The surgical hub 106, 206 can cross-reference the received data with the retrieved steps of the surgical procedure to determine that an energy instrument being fired at this point in the process (i.e., after the completion of the previously discussed steps of the procedure) corresponds to the dissection step. In certain instances, the energy instrument can be an energy tool mounted to a robotic arm of a robotic surgical system.
Tenth step 5220, the surgical team proceeds to the ligation step of the procedure. The surgical hub 106, 206 can infer that the surgeon is ligating arteries and veins because it receives data from the surgical stapling and cutting instrument indicating that the instrument is being fired. Similarly to the prior step, the surgical hub 106, 206 can derive this inference by cross-referencing the receipt of data from the surgical stapling and cutting instrument with the retrieved steps in the process. In certain instances, the surgical instrument can be a surgical tool mounted to a robotic arm of a robotic surgical system.
Eleventh step 5222, the segmentectomy portion of the procedure is performed. The surgical hub 106, 206 can infer that the surgeon is transecting the parenchyma based on data from the surgical stapling and cutting instrument, including data from its cartridge. The cartridge data can correspond to the size or type of staple being fired by the instrument, for example. As different types of staples are utilized for different types of tissues, the cartridge data can thus indicate the type of tissue being stapled and/or transected. In this case, the type of staple being fired is utilized for parenchyma (or other similar tissue types), which allows the surgical hub 106, 206 to infer that the segmentectomy portion of the procedure is being performed.
Twelfth step 5224, the node dissection step is then performed. The surgical hub 106, 206 can infer that the surgical team is dissecting the node and performing a leak test based on data received from the generator indicating that an RF or ultrasonic instrument is being fired. For this particular procedure, an RF or ultrasonic instrument being utilized after parenchyma was transected corresponds to the node dissection step, which allows the surgical hub 106, 206 to make this inference. It should be noted that surgeons regularly switch back and forth between surgical stapling/cutting instruments and surgical energy (i.e., RF or ultrasonic) instruments depending upon the particular step in the procedure because different instruments are better adapted for particular tasks. Therefore, the particular sequence in which the stapling/cutting instruments and surgical energy instruments are used can indicate what step of the procedure the surgeon is performing. Moreover, in certain instances, robotic tools can be utilized for one or more steps in a surgical procedure and/or handheld surgical instruments can be utilized for one or more steps in the surgical procedure. The surgeon(s) can alternate between robotic tools and handheld surgical instruments and/or can use the devices concurrently, for example. Upon completion of the twelfth step 5224, the incisions are closed up and the post-operative portion of the procedure begins.
Thirteenth step 5226, the patient's anesthesia is reversed. The surgical hub 106, 206 can infer that the patient is emerging from the anesthesia based on the ventilator data (i.e., the patient's breathing rate begins increasing), for example.
Lastly, the fourteenth step 5228 is that the medical personnel remove the various patient monitoring devices from the patient. The surgical hub 106, 206 can thus infer that the patient is being transferred to a recovery room when the hub loses EKG, BP, and other data from the patient monitoring devices. As can be seen from the description of this illustrative procedure, the surgical hub 106, 206 can determine or infer when each step of a given surgical procedure is taking place according to data received from the various data sources that are communicably coupled to the surgical hub 106, 206.
Situational awareness is further described in U.S. Provisional Patent Application Ser. No. 62/659,900, titled METHOD OF HUB COMMUNICATION, filed Apr. 19, 2018, which is herein incorporated by reference in its entirety. In certain instances, operation of a robotic surgical system, including the various robotic surgical systems disclosed herein, for example, can be controlled by the hub 106, 206 based on its situational awareness and/or feedback from the components thereof and/or based on information from the cloud 104.
In various aspects, a surgical hub system can be configured to collect rich contextual data pertaining to the use of surgical devices that are connected to the system, providing a hierarchy of awareness for the surgical hub system.
Various techniques are described herein for data transformation, validation, organization, and fusion.
One issue that arises in the surgical hub system context is how to fuse data from diverse and different sources into a common data set that is useful. For example, what solutions are available to fuse two types of data that are recorded at different sampling rates? Can systems be made to be sampled at a similar rate? Can one insert a timing signal into all data to assist in synchronizing the data sets? The solution selected for various applications can depend on the particular types of surgical devices that are collecting the data sets being fused and other such factors.
In one aspect, the surgical hub can be configured to perform automated data scaling, alignment, and organizing of the collected data based on predefined parameters within the surgical hub prior to the data being transmitted. In one aspect, the predefined parameters could be established or altered by interaction between the surgical hub and the cloud system when configured for use. The cloud system may provide solutions from other hubs in the network that addressed a similar problem, and may also provide offline processing using various learning mechanisms to determine how to align the data. This enables the data collected by the surgical hub to be directly integrated into a larger cloud based database for analysis. In another aspect, the surgical hub and/or cloud system can be configured to change the sampling rate of measured systems. For example, the datasets could be organized into a functional database and/or analyzed via functional data analysis. For example, the system can be configured to include computational tabulation of multiple measures from the same or different devices into a single measure. For example, the system can be configured to include a hash function to encrypt or authenticate the source or sources of the data.
In one aspect, the surgical hub system can be configured to perform “data wrangling” or “munging,” i.e., the reorganization of raw data into a usable form. For example, the surgical hub system can be configured to organize data from the surgical hub and other equipment into a unified dataset.
One challenge with integrating and fusing datasets are differing data rates, data configurations, file formats, and organizational methods of the data sources. Further, in moving the data into a single storage framework, it is useful to include the context of what were the conditions under which the data was recorded, any modification of the data into the expected format, and any calibration alteration of the data to make it what is directly comparable, as some examples.
In one aspect, data can be loaded into the data warehouse 204015 via a number of different techniques. Known techniques for transferring data may be used, preserving the formats of the data. The speed at which the data may be transferred may be based more so on the means of transferring the data, such as through what physical means or if the data is transferred wirelessly. Utilizing hardware may be much faster than relying on software, as another example.
In one aspect, organized data can be loaded into a functional database for analysis. The process of data loading can depend on the structure of the data warehouse 204015. For example, metadata tends to be dramatically larger in size and significantly more ancillary to the primary data itself. Therefore, the data might be pooled/stored in one location so that it can be referenced faster/on the fly and the metadata could be stored in another location (e.g., offsite) and/or in a storage medium more appropriate for long term storage so that it is referenced when necessary or when directly asked for. Accordingly, the system can be configured to parse out the data and send it to the appropriate repositories. In such aspects, different datasets or data types could be manipulated in the absence of each other or the metadata could be used as a means to modify the primary data and then be put back in storage or otherwise removed from the combined dataset to limit the size of the dataset.
In another aspect, all the parts of the data (i.e., primary data and/or metadata) can be stored in predefined locations and a reference database can be configured to retrieve each of the pieces of data that are required by the current analysis, rather than having all the data stored in one cohesive database.
In one aspect, the data warehousing system 204015 can be configured to fuse dissimilar data, such as high and low-volume data. In one aspect, data that is received which is in a different format or structure than another dataset could use the metadata linked to the data point to allow the data to be fused into a format that is compatible with the other dataset. For example, data that is recorded at a vastly different data rate could be duplicated and placed in empty cells of a data storage structure. This technique can be used if, for example, the data source is a non-critical or supplementary data element or metadata to another critical data point. As another example, if the data rate is very high and it is being merged into a lower, more critical data form, the average of the data points or dropped data point methods could be used to provide a mean homogenous data flow. To illustrate, if kHz harmonic transducer data (i.e., transducer data that is sampled at a kHz rate) is being combined with or into outcomes-based 30 Hz data, the average of each 1,000 data points for blade impedance could be used with the lower sampling jaw clamp force to create a uniform time-based data stream. As another illustration, 3D imaging data could be transformed into a 2D planer version in the plane being measured by the adjacent mechanical device. In some aspects, the cloud system may help facilitate the determination of which data sets are more important than others, so as to determine how to effectively combine and align the data. Using situational awareness, the cloud system may recall from other datasets or various medical procedures which types of data are relied upon and most commonly adhered to. These datasets used by surgeons, analysts or others may provide probabilistic indications of what types of data are most useful, and then determine how to fuse the data for these purposes.
In various aspects, the data coming from one or more sources connected to a medical hub may be sent to the data warehouse and organized, scaled, and/or aligned using predefined parameters within the medical hub. That is, before integration or aggregation into the cloud system, the data may already be processed to fit a predefined format, scale, or other alignment when it is collected at the medical hub. In some cases, these predefined parameters may be adjusted after interaction with the cloud system. For example, the cloud system may determine that some data needs to be revised after including new medical devices into its system. As another example, the cloud system may utilize situational awareness or other machine learning to determine a more efficient scale of certain types of data that is more useful to an end user. These kinds of changes may be propagated to each of the medical hubs such that the automated data scaling, alignment, and organizing at the medical hub can provide more relevant data before being uploaded to the cloud system.
Data cleaning, also called data pre-processing, refers to the removal of duplicates, re-orientation of columns or rows, and linking of interrelated data.
In one aspect, the data warehousing system 204015 can be configured to remove duplicate data. Data duplication can result from the fact that data could be coming into the data warehouse system 204015 from multiple sources (see block 204005), several of which might be being used together during the course of a surgical procedure. For example, a robotic hub, an energy/visualization hub, and a monitor tower hub could all be interfacing within the same procedure, and each of these hubs may generate at least some data that overlaps, but is ultimately useful to have combined and aligned. Further, the hubs could be moved in and out of the OR for portions of a surgical procedure and even moved into other procedures. Being able to look for duplicate data sets coming from different sources and then being able to remove the duplicate data would keep specific users, usages, or regions from overly influencing conclusions drawn from the overall dataset resulting merely from duplication of the data. As another example, data might be duplicated due to an interruption or loss of data in transit, initiating a second transmission of the same data. As yet another example, data could be intentionally uploaded multiple times. All of these duplicates would affect the weighting of certain conclusions drawn from the datasets, which could interfere with trends and analysis.
In one aspect, the data warehousing system 204015 can be configured to merge separate streams of data. An alternative to multiple duplicates of data might occur when each of a series of devices or hubs that were used in the same procedure all send their data separately to the data warehouse 204015 assembling them. This presents an unrelated problem in that each device will require some fashion of synchronizing some continuous measure that allows the devices to be related with respect to one another. In aspects where the patient data is anonymized, then synchronization of the data from the different data sources can be even more challenging because a single synchronized real-time clock may not be an acceptable synchronizer (as storing real times associated with data could be used to ascertain confidential patient data). Further, if a randomized date and time are generated, then the randomizer would need to communicate that starting point to all devices to allow them to use the same time measure.
In one aspect, the surgical devices are configured to use the time of their internal clocks, rather than real-time, and communicate a synchronizer signal between the devices within the same procedure. Accordingly, each device records and time-stamps the data from their individualized points of view and then once all of the data is transmitted to a data warehouse (e.g., data warehouse 204015), the data warehouse could synchronize the signals and use that to interrelate or fuse the different data feeds into a signal unified dataset. This addresses the patient privacy issue while still successfully synchronizing the data.
In one aspect, a portion of the metadata can be utilized to transform primary data points into related aspect data. For example, the data warehousing system 204015 could be configured to use tissue type to calculate a constant that is then multiplied with the tissue impedance to balance collagen level and conductivity with the impedance to create a comparable impedance value to evaluate seal strength that is comparable between tissue types. As another example, the data warehousing system 204015 could be configured to use tissue thickness and cartridge color for a surgical stapling instrument to calculate a constant that is then multiplied by force-to-fire (FTF) to create a tissue-independent value of device firing performance.
In one aspect, the generation of a particular surgical instrument or its serial number can be utilized to transform the instrument's behavior into a cascade that allows all devices to be compared across multiple design changes. The cloud system may propagate the change from one medical hub that is connected to the particular surgical instrument to all of the other medical hubs to the extent relevant. The new changes may also be incorporated into updating situational awareness for the medical device, noting that a new or updated version of the surgical instrument leads to a modification that should be taken into account.
In one aspect, chronological interrelated data can be stored as part of the patient's electronic health record (EHR) within HIPAA-controlled and protected privacy limits. The patient may then have access to a combined set of data derived from multiple different data sources. If for example multiple medical hubs and/or multiple medical devices were used in a surgery, the patient may be able to see how all of the instruments may have interacted in a chronological fashion, based on the fused and aligned data according to the processes described herein.
In one aspect, non-trackable, seemingly unrelated data pairs or clusters can be integrated with outcomes. In one such aspect, the data wrangling process can include randomized data pairs and allowing the metadata resulting from the data to continue to be correlated to the outcomes which exist as part of the data pair or bundle.
In various aspects, the fit and form of the data can be transformed so that the data is in an expected format (e.g., a format expected by the data warehousing system 204015). In one aspect, raw data can be mapped into particular functional forms at the data staging module 204010. For example, numeric data elements can be substituted for alphabetic data elements. In another aspect, data can be transformed into a predefined configuration, such as a particular arrangement of rows, columns, fields, cells, and so on.
Illustration 204100 in
This measured blood pressure curve in graph 204105 may then may fused with other sampling data to create a fused blood pressure graph 204110. The time period is aligned as shown, along with additional data that may be gathered from other data sets. For example, the line plot 204140 may be a set of data from a slower sampling rate but that was recorded over the same time period. The blood pressure plot 204135 may be generated in part by the sampled data points in plot 204105, but also additional data. In the fused plot 204110, because the data warehouse 204015 would have processed the data to integrate it, error data points like points 204120 may be smoothed out. They may be removed and the revised plot 204135 may have in their places an average of the last data points before and after, in some cases. In other cases, simply the last data point may replace the error points if the rate of change of the data over unit time is greater than a predefined threshold.
The plot 204115 shows an example of low frequency data scaling. A downward sloping plot 204155 sampled at 100 Hz may be overlayed with data sampled at a lower frequency but then upscaled to be aligned with the higher sampling rate. Shown around the 100 Hz sampled plot 204155 are some data plots 204145 and 204150 that are sampled at 10 Hz but scaled to 100 Hz to match the higher sampled plot. Plot 204145 is an example of an error in the lower sampled plot but which is filled in and/or replacing the error points. As shown, the lower sampled points are scaled simply in a horizontal fashion at the higher frequency rate, in this example. In other cases, if enough data points are shown to establish a non-horizontal slope, the data warehouse 204015 may extropolate the lower frequency sampling to create a more smooth fit, for example following the downward slope of plot 204155.
Illustration 204200 in
As discussed above and illustrated in
In various aspects, the computer system can be configured to validate the datasets themselves and/or the sources of the datasets, including the hubs, the individual instruments, or sensing systems. Further, a computer system (e.g., the surgical hub and/or cloud system) can be configured to validate received data and provide reactions to invalid data.
In one aspect, hub, instrument, and/or cloud can be configured to provide particular responses based on validation of a received dataset and authentication of its source and integrity. Further, the response(s) provided by the hub, instrument, and/or cloud could be selected from a set of reactions corresponding to the data and/or metadata. In one aspect, the cloud can be configured to isolate data from the primary data group in response to poor data integrity, a lack of data authenticity (i.e., the inability to authenticate the data or the ability to determine that the data is inauthentic), or user behavior. In another aspect, a computer system can be configured to provide a variety of responses, including identifying the user or the facility, isolating the data from other datasets, compiling the effects of the data to determine warehouse reactions, and/or providing warnings of inviolate instruments for procedures and their implications. In one aspect, the hub can be configured to provide a variety of responses, including flagging the data for later analysis, varying control algorithm changes of linked instruments, or preventing of usage of the hub or the instruments based on the validation or authenticity of the data, instruments, user behaviors, or linked data sources. In one aspect, a local user could have the ability to override the local Hub's reaction.
In one aspect, the computer system can be configured to verify trends within the data to confirm that its behavior and therefore its data are unaltered. There could be several sources of error or invalid information that might move into large datasets. If all data is treated as valid, it could impact the statistical significance of other data points as it would create data that could move an average/correlation or increase the error term of the analysis to make insignificant something that was a significantly different event. Still further, data could be maliciously altered with the intent to hinder the ability to improve or detect something or cause the computer system to modify the devices' behaviors (e.g., control algorithms for the devices) in the wrong direction. Malicious intent could come from hiding the use when a device is being used off label, too many times (i.e., more times than recommended by the device manufacturer), or even in abusive manner. The intent could also be to damage the ability to effectively determine trends in the data or even to misdirect the data analysis.
There are sequential trends and repetitive data points that could be used throughout any normal surgical procedures that could not be fooled if the device was used for the jobs and when it was said to have been used. In one aspect, these comparison points could be used to verify the integrity of the data. This analysis of sequential trends and repetitive data points could not only be a check to verify a validation or encryption term, but it would also be as an on-the-fly means to assure that the data itself has not been affected in some way.
In one aspect, a validation term and/or private key encrypted checksum can be utilized to verify the data received is truly from the instrument it says it is from. For example, a validation term could be used as opposed to encrypting all data and metadata, which could be costly from a bandwidth, storage size, and processor speed point of view. Using a validation term could allow the data to be scanned in a less onerous manner via an encryption algorithm and key to allow the cloud and surgical hub units to verify the data is real and came from the purported specific source.
In one aspect, the cloud system may utilize data from other sources, such as one or more other medical hubs, to determine whether a dataset from a different medical hub is valid. The cloud system may be configured to draw from patterns of known valid datasets in multiple other medical hubs, and/or known invalid datasets from these multiple sources. In other cases, the cloud system may cross check data to determine whether the dataset is unique and whether that dataset should in fact be unique. For example, if data from a medical instrument that has a certain serial number happens to match a serial number from another known medical instrument, the dataset could be flagged.
In one aspect, if new malicious actors are discovered, the cloud system may utilize situational awareness to propagate the known instance of fraud or malicious activity to other hubs in the network. In general, situational awareness may be used to determine patterns of valid or invalid data and may apply those patterns to new situations or new nodes (e.g., hubs) in the network when determining the validity of any dataset.
In one aspect, if the data is found to be altered, the computer system can be configured to determine if the data is entirely contrived or has been modified.
If the data is determined to be entirely contrived or artificial, then the computer system can respond by notifying a security agent of the intrusion and to initiate an investigation into the data source and behavior; quarantining all data and data requests from the affected hubs, regions, or system users; and/or preventing erroneous data from being added to any of the databases (e.g., a data warehousing database) or from affecting or being considered as part of any analyses.
If the data is determined to be altered (e.g., in order to affect data correlation analyses), but is determined to be from a valid source, then the computer system can respond by flagging the data and identifying the data source as a source of contaminated data. An example of this would be for a knock-off device that knows it is being monitored to generate slightly off data with the intent to hide the fact that it is not as effective as the original devices. Another example would be for a repossessed device to contain a mathematical constant that is used to offset the aging calibration of the original device that has been affected by its uses (i.e., overuse) or re-sterilization. These datasets could be verified by the instrument being instructed to operate in a given way during a controlled situation. For example, an instrument can be programmed to close the jaws at first start up, activate the transducer with a known power level, and then review the blade harmonics. As another example, a powered stapler can be programmed to retract the firing member when the knife is in its fully retracted state and monitor the force measured by the system. By being programmed to operate in a particular known manner in a controlled situation, the instrument can thus determine whether its operation is being altered or otherwise affected.
If the data is determined to be invalid and it has characteristics of invalid data that the system has seen before, the data could be used to determine the source and purpose of the invalidation. The data could then be relayed back to the hub from which it came to inform the users that they are being affected by products or individuals that are interfering with the proper operation and best outcomes of their devices.
In some aspects, contextual information can be layered onto data to enable contextual transformation, rather than merely aggregation, of datasets. In other words, contextual metadata can be linked to the outcome and device data to enable contextual transformation of the datasets.
In one aspect, a system (e.g., a surgical hub system, a cloud analytics system, and so on) can be programmed to adjust devices' control programs based on stratified contextual data, in addition to the data. The contextual data represents the circumstances around the collection of the data or related patient, procedure, surgeon, or facility information. The stratified analysis for determining interrelationships of influencing factors can be utilized to create an improved causational response for the surgical hub and instrument control program updates. In one aspect, the stratification of context includes a hierarchy of influencing factors, where some can be more important or functionally interrelated at a higher priority than other interrelations. In one aspect, the data pairs include the outcome of the instrument operation and its functional parameters. In one aspect, the contextual parameters are derived from the patient complications, other treatments, co-morbidities, procedure complications, previous instrument functional parameters, and so on. In one aspect, the adjustments based on these contextual limitations or influencing factors can proportionately affect the adjustments.
In the example B 204510, adjustments to device control parameters may be made after resolving conflicts between different tiers in a non-standard manner. For example, a primary dataset of contextual information may contain a max force to fire of 4001bs, while a secondary dataset of contextual information related to what type of medication a patient is taking may indicate a max force of only 150Ibs. A tertiary dataset of contextual information may have additional instructions for max force to fire based on patient parameters. In this case, the secondary contextual information may override the parameters of the primary contextual information because the patient possesses a high BMI, or there is some other overriding constraint. In some cases, the primary contextual dataset may include one or more exceptions to defer to different parameters, if they exist in other lower tiered datasets. In this case, the primary dataset may provide an exception to use different max force to fire if patient medication requires it, and thus the secondary contextual dataset will override this condition for this case.
In the example C 204515, adjustments of control parameters may be determined by combining multiple pieces of contextual information, rather than simply overriding one over another. As an example, a primary set of contextual information may lead to an instruction to set the initial activation rate of the instrument to 8 mm/sec, while a tertiary set of contextual information about patient parameters may lead to an instruction to decrease speed by an additional 20% due to a diseased tissue state. In this case, the effects do not directly contradict, but rather they may be combined to create a revised instruction. Here, the speed set to 8 mm/sec is a decrease from the default 10 mm/sec, which is an initial decrease of 2 mm/sec. The tertiary instruction leads to an additional decrease of 20%, or 2.0*0.2=0.4 mm/sec. Therefore, the final reduced speed is 8-0.4=7.6 mm/sec. The cloud system may be configured to interpret the logic of the instructions and generate the adjusted device parameters based on the combination of contextual information.
In the example D 204520, secondary or tertiary effects can still be used to override any predefined control parameters that a primary contextual dataset does not speak to. Generally, the secondary and tertiary contextual datasets may be based on patient specific parameters, and therefore lead to changes made at the time of surgery or “on the fly.” In some cases, new contextual information may be provided in real time, which may then cause additional adjustments to the device(s).
Next, a second set of contextual information for dealing with a second patient may also be loaded into the instrument but remained queued up before being implemented. For example, for the second patient, contextual information about high blood pressure (e.g., 165/110) may be loaded into the instrument for the disease state. The force to close information for the particular instrument may be loaded for the instrument state. Chemotherapy contextual information may be loaded for the treatment state, and blood thinner dosage contextual information may be loaded for the patient state. Any conflicts or combinations may be resolved using the example processes described in
The resulting combinations of contextual information for the first patient may result in the two graphs 204705 and 204710, for example, for the firing velocity and the force to fire settings over time, respectively. Similarly, the resulting combinations of contextual information for the second patient may result in the two graphs 204720 and 204715, for example, for the firing velocity and the force to fire settings over time, respectively.
In one aspect, the adjustments to the instrument for a single setting may be weighted by the hierarchical tier in which the proposed adjustment derives from. For example, if adjustments to FTF are found in all of the primary, secondary, and tertiary tiers, then the adjustment to FTF may be made according to the following example weighting structure:
FTF=FTF(default)+1.5*FTF(primary)+1.0*FTF(secondary)+0.75*FTF(tertiary),
wherein FTF is force required to fire a surgical stapler.
Other weighting mechanisms may be used as well and are non-limiting.
Discussed below are some non limiting examples of contextual information that may be included to cause adjustments to an instrument. The type and number of factors described may be used in the processes described in
Non-device-specific cues are contextual cues related to the operation of a device, but that are not specific to any particular type of device. Non-device-specific contextual cues can include, for example, device tissue clamping, tissue information, and instrument usage history.
Tissue clamping contextual cues can include, for example, implications of clamp force or pressure on tissue (i.e., the primary effect(s) of the tissue clamping), which can in turn include desired and adverse impacts on the tissue. Clamping of tissue can have multiple different desired effects on the clamped tissue. For example, clamping the tissue can drive the fluids out of the tissue, collapse the tissue layers, and collapse any interior opening(s). This allows the tissue layers to be in close proximity and prevents leaks from any hollow structures in the area (e.g., capillaries, bronchi, gastro-intestinal). Another desired effect of tissue clamping is that because body tissues are viscoelastic, the compressibility of the tissue is dependent on the type of tissue, its fluid content, the pressure level, and the rate of compression. Accordingly, for the same amount of compression, the faster the compression, the higher the applied force. For a constant pressure, the tissue will continue to move thinner and thinner until a stable state of full compression is achieved. This continued thinning is defined as tissue creep and is a function of the viscoelasticity of tissue. This is important in the discussion or pre-compression cycles, wait times, and overall instantaneous compression. Overall lower compression levels over a longer period of time are less detrimental to the treatment tissue and the pressure differential (shear) on the adjacent tissue.
Clamping the tissue can also have adverse impacts on the tissue due to compression. For example, as the tissue is clamped and tissue structures are collapsed, there may be structures in the tissue that are not intended to be collapsed. This can create a micro tissue tension or pressure differential between the adjacent unclamped tissue and the compressed tissue. Some tissues (e.g., parenchyma, solid organ parenchyma) are not particularly tolerant to such tension or pressure without causing ruptures of the tissue layers adjacent to the clamped tissue, which in turn causes inadvertent collateral tissue damage and, potentially, additional leaks. The total amount of pressure, the geometry of the clamping bodies, and the rate of clamping all have primary effects on the likelihood of collateral damage. Furthermore, the tissue composition, strength, and internal parameters also have an implication of the likelihood of damage. Many of these internal parameters of the tissue are influenced by other medical treatments, disease states, or physiologic states of the tissue. All of these can complicate the likelihood of collateral or primary site secondary damage. As another example, the maximum compression levels for different tissues and organ are at different levels. Most tissues in the body are a series of layers or structures enclosed within other structures. Once maximum compression occurs when the outer enclosing layer has too much pressure or pressure differential applied, it tears, allowing the internal constrained tissue out. The lung is a good example of this. The lung parenchyma is made up of alveoli, veins, arteries, and bronchi with an exterior visceral and parietal pleura covering the surface. When stapling lung parenchyma, it is desirable to staple the pleura to itself to promote good healing. But a tear in the pleura can expose the more fragile alveoli and without an outer constraining element, the alveoli easily rupture, creating air leaks. Another form of maximum tissue compression occurs when the fiber bundles of the tissue itself are ruptured or separated. This occurs at a much higher level and this tissue destruction is typically accompanied by wide spread cellular death and necrosis.
A number of different device control parameters influence clamping, such as the clamping force, the clamping rate, and the number of repetitive clamps. The clamping force characteristics can be illustrated by a clamp force vs. time curve, which can indicate the time rate of change of force, peak clamping force, time to clamp force stabilization, steady state clamping force, and difference between peak clamp force and stabilized clamping force.
Clamping force can be measured either directly or indirectly via a proxy. A number of different proxies can be utilized to measure the clamping force. For powered closure, the proxies can include the current through the motor and the difference between the target motor speed and the actual motor speed. Strain gauges on components that are loaded during the act of clamping, such as the anvil, the closure member, and/or the support frame can also be utilized to measure the clamping force.
Clamping rate can be determined by comparing the actual clamping rate against the targeted clamping rate for powered closure. Clamping rate can also be determined according to the duration of the clamping process from start to finish.
The number of repetitive clamps can be important because heavy tissue manipulation prior to transection of tissue treatment can have a cumulative effect on the tissue due to the repetitive exposure of pressure to the tissue. Some devices have a maximum pressure that can be applied and also a minimum closure level for the next mechanism to begin its operation. In these instances, the jaws are opened and closed repeatedly to get the tissue to the minimum closed state while compressing over and over until that state is achieved. In one aspect, a robotic surgical system can signal if clamping parameters do not fall within a threshold to ensure the jaws are properly clamped.
Tissue information contextual cues can include, for example, placement in jaw (which can be considered, e.g., a secondary effect from the surgical procedure), tissue quality knowledge from other sources (e.g., imaging or EMR, which can indicate prior interventions, current/prior diseases, and so on), type, thickness or density, and impedance (which can be considered, e.g., a primary effect from the surgical procedure). The placement of the tissue within the jaws can correspond to the percentage of the jaws covered by the tissue, the region or locations of jaws covered by tissue (e.g., vessel, etc.), and the degree of bunching or degree of uniformity of the tissue along the length of the jaws. Any device that compresses tissue is applying a known measurable force to the tissue within the jaws. The amount of tissue in the jaws, the placement of the tissue (i.e., relative distal to proximal position), and its thickness variability impact the pressure on the tissue. Knowing the force applied to the tissue without knowing how much of the jaws are covered by the tissue or the placement of the tissue makes it challenging to determine the pressure on the tissue. Many devices are also technique sensitive. For example, often only the distal tip of an ultrasonic device is used for dissection, welding, and cutting, leaving the bulk of the jaw empty for many of the firings. As another example, surgical stapling and cutting instruments often have the tissue crammed into the proximal crotch of the jaws, leaving a differential of tissue from the proximal to distal end of the end effector. Unless the only meaningful information that is sought is the trends of the parameters (which can be the case in certain situations), adjustments to the device control parameters are functionally dependent on knowing how much of the jaw is loaded and where the jaws is loaded because those factors have implications of the forces measured.
Instrument usage history contextual cues can include, for example, the number of uses and the number of resterilizations of the devices.
There are a wide variety of device-specific contextual cues for staplers, ultrasonic instruments, laparoscopic or endoscopic suturing devices, dual bipolar instruments, monopolar instruments, and clip appliers.
Contextual cues for stapling devices can include device and reload identification cues and firing speed cues (which can be considered, e.g., a primary effect from the surgical procedure).
Device and reload identification cues can include, for example, the stapler type and reload (i.e., cartridge) information. Stapler type cues can include the brand, powered verse manual, shaft length, general purpose verse specialty, handheld verse robotic, single verse multiple use, usage history, whether the device has been reprocessed (e.g., authentic reprocessing or resterilized, off-label usage), and stapler configuration (e.g., linear, curved linear, or circular). Reload cues can include the color, length, uniform verse variable staple height, authentication (i.e., whether the reload is compatible and of the same brand; whether the reload is compatible, but of a different or unknown brand device or an illegal knock-off reload used with the manufacturer's stapler; not compatible; or of the correct technology generation, such as a), specialty (e.g., curved tip, reinforced, radial, absorbable staples, medicament-coated staples, or tissue thickness compensation), use and type of buttress or other staple line adjunct, or provides medicament delivery via staple line adjunct.
Firing speed cues can include, for example, actual speed verse time throughout the firing cycle, the difference between the target speed and the actual speed, or adaptive firing control of firing speed (e.g., starting speed, the number of changes in target speed, and the maximum and minimum actual speeds recorded). Firing speed has multiple direct and/or indirect implications on device function. For example, firing speed can have implications of staple formation for multiple reasons.
As one reason, the rate at which an I-beam or bladed actuator is cycled causes tissue to move while the staples are being deployed. In a circular stapler, the knife advancement is often coupled to the staple driver advancement. If the knife begins to sever the tissue before the staples are fully formed (as may be the case), the tissue begins to move radially outward. This tissue flow can have implications on the staple formation. In sequentially linear deploying staplers, the knife/actuator progresses through the cartridge (typically proximal to distal, although sometimes it can be in the opposite direction) and severs tissue while progressively forming staples, which creates tissue flow in the direction of the movement. Pre-compression and tissue stabilization features can reduce this effect, while lower tissue compressions and I-beam local running compressions typically increase this effect. The tissue movement effect can create a wave in advance of the cutting member, which occurs in a related area to where the unformed staples are being advanced towards the anvil. Accordingly, this tissue flow has an effect on staple formation and cut line length.
As another reason, the rate at which the staple drivers are advanced has an effect on their advancement and the likelihood of them rotating or bending, causing the crown of the staple to move out of plane. For surgical stapling and cutting instruments where the diameter of the device is constrained to the trocar diameter, size, or type, the staple drivers are often short and have an aspect ratio that allows for driver roll, in addition to linear advancement perpendicular to the tissue contacting surface of the cartridge. This driver roll can result in a bind in the advancement of the driver so that as the sled continues to advance, the drivers are rotated, rather than advancing outwardly, resulting in the destruction of the cartridge and the staple line. This roll of the staple drivers is a function of sliding friction, lubrication, and cartridge geometry. The binding and therefore the driver rolling is amplified by the rate at which the sled is advanced and, therefore, the rate of the firing actuator of the device. Furthermore, many staplers overdrive the drivers above the tissue contacting surface of the cartridge. This overdrive exposes the driver to tissue flows occurring between the anvil and the cartridge. The drivers have a moment of inertia and are being driven up into contact with the tissue, as well as experiencing the loads from the staples being formed. The rate at which these drivers are advanced into the tissue and the extent of the overdrive both influence the likelihood of the driver remaining directly under the anvil forming pocket.
As another example, firing speed can have implications on local tissue compression. In the case of I-beam coupled surgical stapling and cutting instruments, the advancement of the firing member causes local tissue compression around the I-beam location, in addition to cutting tissue and deploying the staples against the anvil pockets. This local running compression wave moves proximal to distal with the I-beam location. The viscoelastic aspect of the tissue causes the rate of this advancement to be directly related to the local compression force applied, as well as the size of the rolling compression wave. This local rolling compression is capable of causing local tissue tension damage within the treatment area, as well as collateral damage because the rate of compression is likely more than the rate of pre-compression.
As yet another example, firing speed can have implications regarding forces within the device. The loads experienced within the instrument itself are a cumulative effect from the pre-compression, as well as the local rolling compression. The faster the firing member is advanced, the higher the required force to advance the firing member. This is due to the dynamics of the moving structures within the device as well as the I-beam forces. The higher these forces are, the more stretch there is in all the components in the elongated tube and frame, which in turn results in some forces being impacted (e.g., pre-compression deteriorate as the system stretches). These losses then add more force to the firing member balance, resulting in even higher impacts on the firing speed to load relationship.
These various examples of stapler contextual cues can be further illustrated with regards to a specific example. In this example, through the procedure plan, EMR, and other hospital records, several things are known: (i) this is a right upper lobectomy procedure; (ii) the patient has had prior radiation to treat the tumor in this area; and (iii) the patient has interstitial lung disease. These pieces of information suggest that the lung will be stiffer than normal, healthy tissue. Based on this inference, the conservative approach would be to slow down the maximum rate of closure and adjust the thresholds. However, further layered contextual information can be further utilized in determining how the instrument should be controlled. On this same patient, during closure, the force to close is higher than anticipated, exceeding the new thresholds (i.e., the thresholds that we set according to the procedure and patient information noted above). As a result, the wait time prior to starting the firing sequence is increased and the initial firing speed is slowed. Firing algorithms will take over once firing has been initiated. Note that the contextual cues can influence thresholds within the firing algorithms.
Contextual cues for ultrasonic devices can include the activation time, the coherence tomography evaluation of the collagen content of the tissue, the current blend of energy modalities (e.g., whether the instrument utilizes an ultrasonic/bipolar blend, an ultrasonic/monopolar blend, or ultrasonic only), blade temperature, and pad condition. Blade temperature increases with the duration of contact with either tissue or the clamp arm pad and the power into the transducer. This temperature changes the natural frequency of the blade and has the ability to add heat into the welding of tissue that is not intended. It can also cause inadvertent damage to tissue that it comes into contact with, even in-between actuations of the instrument. Hot blades also cause local tissue charring (which can then stick to the blade). The blade temperature has a long-term effect on cut/coagulation performance, but also creates a shear or tearing force on the tissue weld as the jaws are unclamped and removed (as charred tissue sticks to the blade). The pad condition can depend upon the duration of time active without tissue in the jaws and/or the temperature history of the jaws. As the pad is degraded, the underlying metallic strength of the clamp arm is exposed to the blade, eventually impacting its performance.
These various examples of ultrasonic contextual cues can be further illustrated with regards to a specific example. In this example, through the procedure plan, EMR, and other hospital records, several things are known: (i) this is a vertical sleeve gastrectomy procedure; (ii) the patient's BMI 40; and (iii) the patient's body composition suggest that they have a high level of visceral fat. These pieces of information suggest that the greater curvature takedown will have a higher than normal volume of fatty mesentery. Based on this inference, the blended algorithm leans more heavily toward cutting than sealing given the high expected fat content. Algorithm parameters can be concurrently adjusted to ensure a robust seal.
Contextual cues for laparoscopic or endoscopic suturing devices can include stitch tension (tension monitoring can be utilized to inform the suturing technique, for example), stitch type (e.g., mattress verse running, etc.), or suture type (e.g., braided verse monofilament, absorbable verse non-absorbable, suture diameter/size, or needle size/type). Pattern recognition models can be utilized to recognize the pattern of the stitches placed verse tension applied in applying the stitches (e.g., stitch/tension/stitch/tension verse stitch/stitch/tension/stitch/stitch/tension). The pattern recognition system can be configured to provide technique advisements, e.g., three stitches without a tension step with a braided suture may be difficult to cinch up without tissue damage, whereas two stitches may be suitable.’
Contextual cues for dual jaw bipolar RF instruments can include the coating (which can include coatings disclosed in U.S. Pat. Nos. 5,693,052 and 5,843,080, which are each hereby incorporated by reference in their entirety), design (which can include the design disclosed in U.S. Pat. No. 399,561D, which is hereby incorporated by reference in its entirety), bipolar coagulation, algorithms and load curves, smoke generated, conductivity contact of electrodes (e.g., the amount of charring present on electrodes or whether there is a detected short), jaw compression (e.g., the compressive force, pressure, or in the special case of bipolar shears the localized electrode cross-section/elevated geometry or higher max force, as is disclosed in U.S. Pat. No. 9,084,606, which is hereby incorporated by reference in its entirety), tissue gap (i.e., whether the jaw is open/feathering or closed/spacing between jaws), electrode configuration (e.g., opposed electrodes, offset electrodes, or electrodes/insulation, as disclosed in U.S. Pat. Nos. 5,100,402, 5,496,315, 5,531,743, 5,846,237, and/or 6,090,107, each of which is hereby incorporated by reference in its entirety).
Contextual cues for monopolar instruments can include power (e.g., constant voltage or current and variable control of the other given a tissue impendence), tissue impendence (e.g., rate of change of impendence, overall measured impendence, or time at a given impendence), algorithms and load curves, return path capacity, blade technology (e.g., the coating of blade, such as insulation breakdown or various coatings described in U.S. Pat. Nos. 5,197,962, 5,697,926, 5,893,849, 6,685,704, 6,783,525, 6,951,559, each of which is hereby incorporated by reference herein in its entirety; geometry of exposed conductive surfaces; conductivity of structural underling materials; or blade configurations, such as the configurations described in U.S. Pat. Nos. 6,039,735, 6,066,137, 8,439,910, each of which is hereby incorporated by reference in its entirety), heat dissipation, smoke generated, applied compression (e.g., compression force between the mono-polar blade and the support arm or driving force of a monopolar probe pressed against tissue), or leakage current magnitude.
Contextual cues for clip applier devices can include clip size, first verse last clip from the applier, the timing of the detected forces (e.g., overload protection mechanisms if unexpectedly stiff structures are inadvertent within jaws, such as when clipping over another clip or closing jaws on another instrument), clip feeding monitoring (e.g., feeding loads or detection of the presence of clips in pre-defined locations or at pre-defined times), lateral end effector and bending loads, or jaw actuation load (e.g., clip closure, max load in displacement controlled actuation, max displacement in load controlled actuation, or tissue manipulation loads with jaws).
Medical contextual cues can include contextual cues associated with medical complications, disease states, medications, and procedure complexity.
Contextual cues for medical complications can include functional constipation, functional diarrhea, sphincter control or strength insufficiency disorders, functional dyspepsia, and complications that effect tissue planes & tissue compositional makeup, as just some examples.
Functional constipation can result from colorectal surgery including a circular anastomosis, which would suggest a longer period before bowel motility after surgery to allow for more expansion. It could also suggest the use of an expandable staple configuration or counter indicate the use of buttress or compression ring technologies that would not tolerate larger more solid feces (which can be, e.g., a secondary effect from the surgical procedure as a tissue fragility complicating effect).
Functional diarrhea can indicate higher acid levels and more fluidics movements, which could dictate tighter staple forms, higher pre-compressions, and the potential need for abdomen-side applied secondary adjuncts to minimize the likelihood of fecal introduction into the abdomen cavity (which can be defined as a tertiary effect from the surgical procedure).
Poor sphincter control or other strength in sufficiency disorders can result in heartburn or acid reflux. These contextual cues can indicate, for example, that an esophageal anastomosis would benefit from stronger staples, tighter forms, and/or longer precompression of the tissue to enable tighter staple forms and lower tissue tension thresholds (both micro and macro tension). Macro tissue tension is related to more extensive mobilization of the tissue from adjacent structures and could me measured by lateral forces on the stapling device. Micro tissue tension is due to the compression rate, max compression, and the gradient of tissue compression between the areas directly adjacent to the treatment area and the type of staple forms within the treatment area. 3D staples lower micro tension as does a lower max pre-compression level. Heartburn and/or acid reflux can be considered, e.g., a secondary effect of the surgical procedure. Device or surgery suggestions could include a reinforcement treatment for the sphincter or an adjunct therapy applied to the staple lines to improve robustness.
Functional dyspepsia can result from the sensation or inhibition of peristalsis, which could suggest rigidity of the anastomosis line (would further amplify the effect). Lower micro tissue tension would ease the effect (3D staples) or an expandable staple line. Compression of anastomosis lines or adjunct material used on the staple lines would cause more issues. Functional dyspepsia can be considered, e.g., a secondary effect as an adjunct therapy usage complication effect.
In the case of complications that effect tissue planes and tissue compositional makeup, healing from a first surgery and adhesions result in an increase in thickness of the tissue as well as disorganized remodeling of the tissue, resulting in increased toughness of the tissue. To adjust for these effects when stapling, it would be suggested to implement an increased gap, raised tissue load thresholds, slower actuation, and suggested larger or heavier staples. These complications can be considered, e.g., a secondary effect of the surgical procedure as a tissue thickness/toughness complication effect. Other such complications can include revisional surgery, adhesions, and altered tissue conditions from medical treatments (e.g., irradiated tissue or steroid induced changes).
Contextual cues for disease states can vary for colorectal, thoracic, metabolic, and cardiovascular diseases.
For colorectal diseases, inflammatory bowel disease can be a contextual cue. All of the repetitive inflammatory colorectal diseases cause an increase in thickness of the tissue, as well as disorganized remodeling of the tissue, resulting in increased toughness of the tissue. The stapling adjustments could include increased gap, raised tissue load thresholds, slower actuation, and suggested larger or heavier staples. These complications can be considered, e.g., a secondary effect of the surgical procedure as a stapling adjunct complication effect. Such colorectal diseases can include Crohn's disease and diverticulitis.
For thoracic diseases, bronchitis, emphysema, chronic obstructive pulmonary disease (COPD), asthma and interstitial lung disease can all be contextual cues. For example, emphysema results in thicker, stiffer lung tissue that would suggest load clamping rates, lower pre-compression levels, and slower firing actuation of the knife/I-beam to prevent adjacent collateral damage around the perimeter of the anvil and cartridge due to excessive pressure differential during treatment. These are primary effects. As another example, COPD results in artery walls that could be stiffer and less elastic, requiring a softer handling of the arteries prior to applying treatment. This could require the mechanical clamping elements to clamp at a slower rate and potentially a lower clamp pressure to minimize damage outside of the treatment area and premature damage to the treatment area. These adjustments could be for either energy or stapling. These are secondary effects. In stapling, the suggestion of an adjunct many be counter indicated to prevent additional uncontrolled remodeling and hardening. In advanced energy, the RF treatment modality is preferred and the balance of the RF to ultrasonic balance to weld more than cut.
For metabolic diseases, metabolic syndrome, obesity, and type 2 diabetes mellitus can all be contextual cues.
For cardiovascular diseases, arteriosclerosis, high cholesterol, and vascular disease can all be contextual cues.
Contextual cues for medications can include blood thinning, blood clotting, steroids, radiation treatment, and chemotherapy.
For example, blood thinning can indicate that advanced energy devices would benefit from improved coagulation before cutting. This is a priority and primary effect as a blood pressure complication effect. In a hybrid energy device, the RF power could be increased or the ultrasonic application delayed in order to increase the coagulation before the cutting. In an ultrasonic-only device, the algorithm could be adjusted to apply a lower powered level for a longer period of time to in order to denature the collagen longer before cutting. Further, in an ultrasonic-only device the harmonic power could be adjusted lower as the temperature approaches a predefined optimum temperature and that temperature could be maintained for a longer period of time before elevating the power of the transducer to initiate cutting. Further, in a stapling instrument, the suggested cartridge color could be adjusted down, suggesting shorter formed staples or the closure clamping time increased or the pressure increased before firing. This is a secondary effect.
For example, blood clotting can indicate that precompression or the compression levels of either the advanced energy or stapling could be lowered prior to treatment to minimize inadvertent damage and therefore forming clotting outside of the treatment area. This is a secondary effect as an increased pressure complication effect.
For example, steroids cause physiologic effects that slow healing and raise blood pressure, which increases pre-existing complications. This is a tertiary effect as an amplification of disease complication effects, as well as longer term healing complications. Steroids raise blood pressure in many people who take it. One reason is that steroids and other corticosteroids cause the body to retain fluid. Extra fluid in the circulation can cause an increase in blood pressure. Further, anti-inflammatory corticosteroids significantly impair wound healing. Corticosteroids lower transforming growth factor-β (TGF-β) and insulin-like growth factor-I (IGF-I) levels and tissue deposition in wounds and that retinoids stimulate corticosteroid-impaired TGF-β and IGF-I release and collagen production.
For example, radiation treatment can result in inflammation of the organ and thickening of the tissue wall. This effect can increase the stiffness, thickness, and toughness of the tissue being treated. This increases the need for longer compression times and potentially higher compression thresholds, unless complications inhibit that. Radiation treatments can also have complication effects on blood oxygenation thru impacting the respiration system and can have a multiplicative effect on collagen vascular disease which could in turn require changes in any advanced energy welding energy blending or algorithms leaning towards more time to weld at a slower rate before cutting. This is a secondary effect as a tissue composition makeup complication effect.
For example, chemotherapy treatment can result in the tissue becoming thin and friable. These effects make collateral damage to the tissues much more likely and more difficult to treat. The implications for any mechanical device is lower manipulation forces and precompression levels, as well as lower rate thresholds and in general more gentle handling and tissue tensions needed. This is a primary effect as complication effects with higher tissue compressions.
Contextual cues associated with procedure complexity include the location of a tumor, remaining vascularization, the challenge of accessing the surgical site, the total time under anesthesia, the amount of work required to complete the procedure, and whether there were any prior procedures.
For example, the remaining vascularization can be a contextual cue because vascularization is directly related to the rate of healing and tissue viability. Further, it has longer-term implication on tissue strength and recovery. This is a primary physiologic impact on healing. This does not have any short-term instrument operation implications, but does have implications on recovery strength and reinforcement, needing additional time of the primary surgical treatment durability. This may impact the instrument's recommendations for post-surgery recovery, additional adjunct therapies applied, and required monitoring. This is a secondary effect as an amplification of disease state, blood sugar level, and oxygenation impacts on tissue remodeling.
For example, the total time under anesthesia can be a contextual cue because the time under anesthesia is a complicating effect on recovery to pre-surgery levels relating to oxygenation levels and metabolic reactions. During the surgery, it has an amplification effect on lower blood oxygenation levels. This is a time-dependent effect that is not linear; the longer the time, the higher the impact of the effects become. This is a tertiary effect as a complication effect on lower blood oxygenation levels.
For example, the amount of work required to complete the procedure can be a contextual cue because it relates to the number of cycles of energy, the number of dissector or scissors moves, and/or the number of surgical stapling instrument firings.
For example, prior procedures can be a contextual cue because prior procedures increase the likelihood of adhesions and secondary remodeling of tissues. This typically creates more disorganized tissue planes and tougher tissues with more covering tissues. This is a tertiary effect as amplification of disease complication effects, as well as collagen level complication effects.
Patient-specific contextual cues can include, for example, patient parameters and physiologic cues.
Patient parameters can include age, gender, whether the patient is a smoker, BMI, and body composition information.
For example, age results in friable tissues that would require a lower compression and lower rate of compression of the treatment devices, especially in the pre-treatment compressions. This is a secondary effect as a higher tissue compression complication effect.
For example, gender has threshold implication shifts for the ideal ranges of many physiologically related measures (e.g., BMI, body fat composition, and age impacts on physiology). This is a tertiary effect on other parameters.
For example, whether the patient is a smoker results in thicker, stiffer lung tissue that would suggest load clamping rates, lower pre-compression levels, and slower firing actuation of the knife/I-beam to prevent adjacent collateral damage around the perimeter of the anvil and cartridge due to excessive pressure differential during treatment. Theses are secondary effects as emphysema and oxygen saturation complication effects. Tissue oxygenation can be, as noted below, a metric available to quantify effect of smoking.
For example, BMI is a contextual cue because obesity tends to increase co-morbidities of many other medical complications. This is a tertiary effect as an amplification complication effect with blood sugar levels, congestive heart issues, oxygenation levels, and several other disease states.
For example, body composition information can be contextual cues because body fat percentage affects the collagen content of tissues, the compressive properties of the tissue types, and metabolic implications on healing & tissue remodeling. This has effects at both too high and too low of a percentage with differing effects at each extreme. Body fat percentages over a given level inhibit metabolic operation and add to complications around organ function. These complications will tend to amplify disease state complications on the mechanical device functions. Further, body fat percentages below a given level will tend to have impact on the tissue makeup itself. These tissue makeup changes can have impacts both on healing as well as advanced energy devices ability to weld consistently due to fluctuations in collagen levels, requiring more compression and longer weld times. These are tertiary effects as amplification of disease complication effects, as well as collagen level complication effects.
Physiologic cues can include the time since the patient last ate, fasting blood glucose level, blood pressure, macro tissue tension, tissue fluid levels, and tissue oxygenation.
For example, fasting blood glucose level can be a contextual cue because blood sugar level is the main physiologic factor in healing. When blood sugar level is higher than normal, it prevents nutrients and oxygen from energizing cells and prevents your immune system from functioning efficiently. This is a secondary effect. Further, knowing the steady-state fasting state, as well as the post-meal changes and reactions, impact the implications of a measured value. In most humans this varies from about 82 mg/dl to 110 mg/dl (4.4 to 6.1 mmol/l). The blood sugar levels rises to nearly 140 mg/dl (7.8 mmol/l) or a bit more in normal humans after a full meal. In humans normal blood glucose levels are around 90 mg/dl, equivalent to 5 mM (mmol/l)
This measure is also time dependent. Consuming carbohydrate heavy food would cause a dramatic increase in blood sugar, but it would typically also begin to decrease after around 30 minutes.
For example, blood pressure can be utilized as a contextual cue because advanced energy devices benefit from improved coagulation before cutting. This is a priority and primary effect. In a hybrid energy device, the RF power could be increased or the ultrasonic application delayed in order to increase the coagulation before the cutting. In an ultrasonic-only device, the algorithm could be adjusted to apply a lower powered level for a longer period of time to in order to denature the collagen longer before cutting. Further, in an ultrasonic-only device the harmonic power could be adjusted lower as the temperature approaches a predefined optimum temperature and that temperature could be maintained for a longer period of time before elevating the power of the transducer to initiate cutting. Blood pressure can be measured using different methods and at different locations. For example, the 10 minute resting pressure, i.e., resting blood pressure, can be very different than any blood pressure resulting from exertion. Knowing if this is a blood pressure measure based on an acute measure or is considered a systemic resting pressure will have implications on how to respond to the measure and its exceeding of upper or lower pressures. Further, differences exist for vascular levels of blood pressure. Typical blood pressure is taken in larger arteries within an arm or other extremity. A pressure in arteries in the arm of 129/80 could relate to a micro pressure of 70/40 in the capillaries and even lower 20/10 in veins where the actual tissue treatments are being preformed. Occlusions and variations in physiology can amplify or constrain the differences in pressure from one part of the system to another. Knowing where the pressure is being taken and any long-term measures could help adjust the effects needed due to changes in pressure.
For example, tissue fluid levels can be a contextual cue because dehydration reduces blood flow throughout the body, while also consequently lowering blood pressure, it can starve the wound bed of white blood cells that protect against infection, while also limiting oxygen reaching the wound site by way of blood flow, as do vitamins and nutrients. In general, lower fluid levels inhibit every aspect of wound healing. This is a tertiary effect as an amplification of healing complication effects. For surface tissue remodeling and potentially colorectal site healing, dehydration can delay healing in several ways. A warm, damp environment is ideal for the growth of new tissue, and a lack of moisture to the affected area can halt cellular development and migration. Without proper moisture, the epithelial cells that migrate across the wound bed to repair tissue along the way cannot properly navigate and cover the wound site. This interrupts the creation of new tissue and leaves the wound open and susceptible to harmful bacteria that can cause infection. Potential measures as related to dehydration can include, for example, electrolytes, blood urea nitrogen, creatine, urinalysis, complete blood count, and urine and/or blood osmolality.
For example, tissue oxygenation can be a contextual cue because tissue oxygenation is widely recognized to play a role in nearly every part of the wound healing stages. When healing, a surgical site develops an increased need for bacterial defense, cell proliferation, collagen synthesis and angiogenesis, among other reparative functions. Collagen accumulation is a direct function of oxygen tension and levels below 20 mmHg have been shown to impair accumulation. Collagen synthesis is dependent on functions of enzymes that are in turn a function of local oxygen levels. By contrast, hyperbaric oxygen therapy has been shown to increase healing rates by increasing the oxygen concentrations above normal. While the tumor tissue is metabolically designed to thrive under conditions of hypoxia, hypoxia of the wound primarily caused by vascular limitations is intensified by coincident conditions (e.g., infection, pain, anxiety and hyperthermia) and leads to poor healing outcomes. This is a tertiary effect as an amplification of healing complication effects. Tissue oxygenation can be measured according to oxygen delivery (DO2), oxygen uptake/consumption (VO2), oxygen tension (PO2), or hemoglobin oxygen saturation (SO2). Further, several other techniques are available for measuring tissue oxygenation, such as near infrared spectroscopy (NIR).
Procedure-specific contextual cues can include the time of day the procedure occurred, whether it was an emergency versus a planned surgery, the length of the procedure, the type of procedure (e.g., laparoscopic, robotic, or open), and whether it was a reoperative or original procedure.
Surgeon-specific contextual cues can include whether the surgeon was a specialist or a general practitioner (this comparison made against the procedure to be performed), the skill level of the surgeon (which can be indicated by, e.g., the total number of procedures performed, total number of times performed the current operation, and/or training level), and the focus or energy of the surgeon (which can be indicated by, e.g., the number of other procedures performed that day and the duration of current procedure).
In various aspects, the metadata (e.g., the contextual cues described above) can be included with the general data generation.
In one aspect, the metadata can be stored by attaching the metadata to the primary data with the ability to filter the data out from the metadata. In another aspect, the metadata can be stored in a location other than the primary data, but can be linked to, allowing for reaching into the metadata for key metadata.
The accessibility of metadata can be controlled in a variety of different manners. In one aspect, the linked metadata can be transported with the original collected data. In another aspect, data can be extracted from the metadata by filtering data and relevant context.
In various aspects, contextual cues can be organized to provide data based on the needed context. Accordingly, the computer system can be configured to identify or determine the relevance of specific metadata to provide context. Further, a computer system can be programmed to provide navigation thru metadata.
In one aspect, the metadata can be utilized for (i) identification and linking of isolated but interrelated data points or records, (ii) identification of linked occurrences, and/or (iii) algorithms can be programmed to automatically compare outcomes (and complaints) to any/all recorded data and compare regression trends and model capability of prediction to determine which factors can influence success. This data can be limited to a single device (e.g., speed of firing or energy verse leak) or can be combined between multiple devices to infer such things as time of firing relative to placement of trocars or start of anesthesia (beginning of surgery) or number of activations of scissors/dissectors/energy devices (e.g., degree of dissection/removal of fat).
In various aspects, a computer system (e.g., a cloud analysis system, a surgical hub, and/or a data warehousing system) can be programmed to perform automated interrelation and/or integration of multiple data streams into a single interface which has focus areas or areas of additionally accessible or overlayable data. In one aspect, real-time interpreted information can be displayed on a device to the user, where the interpretation is based on data from at least one function of the device and data from a second different source.
In one aspect, interpreted information can be displayed to the user based on at least one function of the device, including at least one data source not originating within the device. In another aspect, the at least one additional source can include a measurement device capable of determining a relevant parameter of the patient to the device's function and the ability of the instrument to automatically update aspects of the secondary information on the display of the device and update it in real-time. In one aspect, the real-time update is achieved by the surgical instrument being able to repeatedly calculate the new data in the select form the user has defined.

The user interface 205004 is configured to display interpreted information based on at least one function of the surgical device 205001. In the example of
In another example, interpreted information associated with blood pressure of a blood vessel in the tissue being grasped, for example, can be concurrently displayed with the firing speed and/or wait-time parameters of the firing stroke. In various examples, the blood pressure can be monitored separately, and blood pressure data, or information interpreted from the blood pressure data, can be transmitted to the surgical device 205001 through a suitable communication link.
In another example, the at least one function can be grasping tissue. Tissue compression or pressure can be a parameter of tissue grasping, which can be displayed on the user interface 205004 and/or modified by user input through the user interface 205004. Furthermore, interpreted information associated with blood pressure of a blood vessel in the tissue being grasped, for example, can be concurrently displayed with the tissue compression or pressure settings
In at least one example, the interpreted information is based on at least one data source not originating within the surgical device 205001. In various aspects, the data source is a separate device that is different than the surgical device 205001. The data from the data source could be interpreted into information relevant to the function performed by the surgical device 205001.
The data interpretation can take place locally at the surgical device 205001. Alternatively, the data interpretation could be performed locally at the data source, and the interpreted information can be routed to the surgical device 205001 either directly or indirectly through a surgical hub (e.g. 106, 206), for example. Alternatively, the data interpretation could be performed locally at a processing unit of the surgical hub (e.g. 106, 206), and the interpreted information can then be routed to the surgical device 205001, for example. Alternatively, the data interpretation could take place at a cloud system 104, which can be configured to route the interpreted information to the surgical device 205001 directly or indirectly through the surgical hub (e.g. 106, 206), for example.
Routing data and/or information between the surgical device 205001, the data source, and/or the surgical hub (e.g. 106, 206) can be accomplished using any suitable wired or wireless communication link. For example, the modular communication hub 203 can be used to route the information and/or data.
In various examples, the data source could be a sensor on another modular device. In various examples, the data source is an imaging device. In at least one example, the data source could be one or more components of the visualization system 108 (
In various examples, an imaging device can be configured to record and/or process imaging data that are relevant to a function performed by the surgical device 205001. Automated image interpretation can then be performed locally at the imaging device, locally at the surgical device 205001, locally at a surgical hub (e.g. 106, 206), and/or remotely at the cloud system 104. A user interface 25004 can then be configured to display the image interpretations concurrently, or simultaneously, with one or more parameter settings associated with the function.
In various examples, the interpreted information is displayed by the user interface 205004 in real-time, or close to real-time. The real-time update is achieved by repeatedly interpreting new data in a selected form the user has defined, for example. The interpreted information can be updated at a predetermined refresh rate, which can be selected by the user of the surgical device 205001.

In various aspects, a surgical hub (or surgical instrument or other system) can be configured to reduce captured images into a representation of outcomes of a transection, for example. In one aspect, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include an algorithm to decompose pixels of an image (e.g., an image captured by a scope) and perform a calculation to determine the color differences between tissue and end effectors and/or leaks (e.g., air bubbles, dye, or blood) to determine the presence, amount, and locations of any leaks (L) or end effectors, as illustrated in the bottom left corner of
In one aspect, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include a classification algorithm for performing digital image processing on an image (e.g., an image captured by a scope) to identify (classify), an end effector, bleeding, bubbles, and other events from other classes of tissue within the image. For example, an algorithm can be programmed to perform comparative pixilation where the image is reduced to a constrained grid pattern and each element of the grid is reduced to, e.g., a 256 color designation for the pixel. A first scan can remove all pixels from the analysis that are not in the correct coloration of the class being sought (e.g., bleeding). Then the potential bleeding areas are compared with either adjacent areas or backward one frame in order to identify flowing blood within the image.
In one aspect, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include an algorithm to perform feature extraction image processing to reduce an image from a near infinite variation of aspects to zones that are formed by reducing the number of random variables to groups of similar variables. For example, a user can select a type of tissue or a feature of anatomy and the imaging system can simplify the characteristic variation within the image to a unified average aspect of the selected feature. This would allow users to find boundaries of tissue planes, different organs, or limits of a tissue surface disrupted by infection or cancer, for example.
In one aspect, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include a pattern recognition algorithm to identify target features. Various such techniques are disclosed in Misawa, Masashi et al., “Artificial Intelligence-Assisted Polyp Detection for Colonoscopy: Initial Experience” Gastroenterology, Volume 154, Issue 8, 202-2029.e3, which is hereby incorporated by reference in its entirety, and can be accessed at www.gastrojournal.org.
In various examples, the control circuit 205012 may receive interpreted information related to hemostasis of tissue previously treated by the surgical device 205001. The interpreted information can be based on imaging data processed by on one or more of the above-described algorithms. As illustrated in the bottom right corner of
In various aspects, algorithms can be programmed to manipulate one image feed to fit another feed to allow for visualization of a static image on a dynamic image. In one aspect, an algorithm can use landmarks and the ability to define the elasticity of the overlay shapes on the primary feed to allow the image to be distorted and forced to fit the moving underlying anchors. This would allow, for example, a pre-surgery CT scan of the tumor or surgical site to be layered over the live feed from the scope during the surgical procedure. This could be used, for example, to extrapolate a pre-surgery image landscape or complex from a portion of the scan which is open to visualization, allowing a surgeon to see tissues or structures that are currently occluded from visible view on a user display.
In various aspects, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can be configured to receive user-selectable, highlightable, or flagable data sets that would display their varying data either numerically, graphically, or as highlightable areas on another image feed.
The user-selectable datasets can be utilized in various surgical contexts. For example, selection of a blood pressure monitor of a selected blood vessel or capillary could be selected because it is to be transected and the surgeon would like to watch the pressure calculated in that region continuously in order to monitor the proximity of dissection to the vessel or adjacent nerve or as a means to decide how long to coagulate a specific region before transecting. As another example, a surgeon could select a series of blood vessels for the surgical hub system to provide a continuous updated visualization feed of the amount of blood moving through the series of blood vessels while they are skeletonized, dissected, and then transected individually. In this example a laser Doppler visualization system can show the magnitude of blood flow measures in a wide area overlaid on the visual image and the fluctuation in blood flow during the interactive dissection steps with the blood flow areas. Such interpreted information can be displayed on the user interface 205004 along with one or more parameters of a function of the surgical device 205001 such as, for example, the firing stroke.
In various aspects, the user can interact with the display of information on the user interface 205004 and select specific sources of additional information derived from data measured, beyond the displayed information. The user then could select the form and frequency the data should be refreshed. The internal processor of the surgical hub (e.g. 106, 206) would then continually update that shading, digital data point, etc. and move it on the display as the selected areas moves on the display. This would allow the user to move and refocus a camera or imaging system and the selected and highlight data would still be measuring and displaying the desired information relative to the user selection.
In at least one example, highlighting based on hyperspectral imaging (i.e., processing an image to visualize particular types of structures) could trigger a warning indicator if the processed image shows something the user should be made aware of, even if the user did not request the particular imaging associated with the warning. For example, if a critical structure is detected, but is not visible under direct visualization, the surgical hub (e.g. 106, 206) and/or device 205001 can automatically trigger a warning so that the user can be made aware of the critical structure.
In at least one example, as illustrated in

In various examples, the automatic adjustment of the field of view of the medical imaging device may include automatic focusing and/or centering based on the location of a critical structure such as, for example, an end effector of the surgical device 205001. In other examples, the critical structure can be an anatomical structure or surgical site location. In at least one example, the center of the area visualized on a monitor 205011 could be automatically adjusted based on user actions or device locations.
Various suitable image interpretation techniques, as described above, can be employed by an imaging module (e.g. 138, 238) to detect 205100 the critical structure and/or assess 205104 its position with respect to the field of view of the imaging device. In one example, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include an algorithm to decompose pixels of an image (e.g., an image captured by a scope) and perform a calculation to determine the color differences between the critical structure and the surrounding environment. The determined color differences are utilized to detect 205100 the critical structure and/or assess 205104 its position with respect to the field of view of the imaging device. In another aspect, a surgical hub (e.g. 106, 206) or an imaging module thereof (e.g. 138, 238) can include a classification algorithm for performing digital image processing on an image (e.g., an image captured by a scope) to detect 205100 (classify) a critical structure and/or assess 205104 its position with respect to the field of view of the imaging device.
In the event it is determined 205106 that the critical structure is at the edge of the current field of view of the imaging device, and the medical imaging device is capable of adjusting the field of view on the locus of the critical structure (e.g. end effector), a monitor 205011 or the surgical field input device (e.g. user interface 205004) could provide feedback by prompting 205108 the user that the field of view could be automatically adjusted with respect to the critical structure, if desired. The automatically adjusted could be a one-time adjustment or a continuous adjustment.
In at least one example, the visualization system (e.g. visualization systems 108, 208) could determine, for example through the user interface 205004, if the user would prefer the system to track and adjust the center focus area of the field of view of the imaging device on a locus of the critical structure. If the user selects the auto-tracking option, as illustrated in
In the event the critical structure is an end effector of a surgical device, the end effector can be articulated to a new position at the center of the field of view per instructions from the surgical hub, for example. Alternatively, the imaging device can be moved to reposition the field of view with respect to the critical structure.
In various examples, the medical imaging device comprises a camera pointed at the end effector 205006 of the surgical device 205001 at a surgical site within a patient cavity. In certain instances, as illustrated at the top left corner of
In various aspects, the machine learning systems of the present disclosure utilizes supervised learning methods to cluster data pairs into non-predefined categories based not only the outcomes, but also on the metadata context. In one aspect, supervised machine learning can be performed on cloud data from the surgical hubs (e.g. 102, 202) to find unidentified data groups. The machine learning cloud data analysis can identify, for example, regional differences in surgical and patient outcomes.
Methods of supervised learning can include, for example, parametric learning methods or non-parametric learning methods. Parametric learning methods can include, for example, regression (e.g., predicting continuous data, discrete data, or gradient descent, which is a sequential process that is used to determine the minimum of the model), classification, and vector clustering. Vector clustering is a process that, given a set of training examples, creates the capability of the system to take new examples and placing them within the grouping defined by the training examples. Vector clustering can also include margin defining, which is maximizing the margin between the groups to minimize the mis-grouping of marginal data points. Non-parametric learning methods can include, for example, decision trees and k-NN algorithms.
Data compilation methods can include, for example, singular value decomposition, normalization, and dimensionality reduction.
In various aspects, the metadata context of the data can be utilized to widen the zone between at least two groups and therefore fit the data to their groups based on the outcomes and their contributing factors. Supervised machine learning techniques can be utilized to define data groups by their outcomes and contributing factors.
The supervision methodology can be adjusted according to validation of groupings and sensitivity.
The sensitivity of the supervision methodology can be adjusted to control overlearning and threshold/probability cutoff of the machine learning model. Overlearning is the adjustability or the ratio of algorithm flexibility to bias. A highly flexible algorithm will fit all variable data into a data set, whereas a highly biased algorithm will fix a very limited set of data points into a data set. Threshold and probability cutoff is the machine learning model's tolerance of false positives versus false negatives.
In various aspects, unsupervised (or “untrained”) learning techniques can be used in order to determine relationships of data pairs from the surgical hub that contain linkages or result from a complication or morbidity, rather than the treatment step directly. In other words, machine learning can be utilized to identify non-device causes and adapt surgical hub responses accordingly.
Unsupervised learning is the process of training a machine learning model on unlabeled data. With time-based or sequential order-based learned outcomes, a program can determine the most likely to succeed next steps based on a predefined number of initial responses. These responses could be issues encountered, patient pre-operative conditions, or encountered issues in the surgical procedure. A number of unsupervised learning techniques can be used, including, for example, clustering (e.g., hierarchical clustering and k-means clustering), which provides protection against potential threats that are outside “normal” learned behavior, and unsupervised simulation of one instance of the program attempting to beat another instance of the program. The unsupervised learning techniques can also include deep learning and neural networks, which are analysis techniques that analyze trends and connections without considering the meaning of the data. Artificial neural networks can be utilized for, e.g., image processing to improve the ability to identify underlying critical structures by identifying images with the areas previously called out on the image, while having no information of the parameters of the structures themselves.
These data points could be used to identify to the user that there is an underlying cause for future evaluation, or that there is the need for additional treatment reinforcement, not because the device is not capable of proofing in a predictive fashion, but because the tissue or patient requires special care.
The result could be the identification to the surgeon that an additional procedure step is warranted, and adjunct treatment considered, or an alternative more robust product is needed. For example, during a colorectal lower anterior resection procedure, an imaging system might detect the over-limitation of blood supply to the region after mobilization as a portion of the metadata generated from the procedure. Accordingly, a vessel regeneration product or drug might be warranted due to the implications of not being able to maintain an adequate blood supply to the transected tissue.
As another example, during a colorectal lower anterior resection procedure, the co-morbidities or chemo treatments might indicate in the metadata generated from the procedure that the tissue is too easily friable. Accordingly, a pressure distributing absorbable adjunct stapling product might be warranted in order to stress reduce the anastomosis, a diversion might need to be created to prevent bowel contents from placing undo stress on the new anastomosis, and/or an oversewing or fibrin/thrombin sealant might need to be applied to insure no undo leaks occurs in the first days of healing. A surgical system 200 can be programmed to recommend the appropriate product, drug, or treatment to the physician after completion of the procedure.
Accordingly, instrument, device, or machine settings can be set according to relationships determined via unsupervised learning techniques to provide better outcomes. In at least one example, a surgical stapling instrument is updated to run slower or faster depending on tissue type, resistance to push the knife, and so on. In another example, energy devices (e.g., ultrasonic surgical instruments and electrosurgical instruments) are updated to change the applied current over the transection (i.e., slowly ramping up or down or taking other such actions). Further, in various examples, one or more of the modular device (e.g. 1a-1n, 2a-2m) of the present disclosure are programmed to automatically update their settings based on the correlations learned by a machine learning performed by the cloud-based system (e.g. 104, 204).
In some aspects, the surgeon could have the ability to override the learned settings. In one aspect, the learned settings could be the default settings. In one aspect, a modular device (e.g. 1a-1n, 2a-2m) could suggest the new settings and allow the surgeon to choose between accepting the new settings and keeping the previous defaults.
A surgical system (e.g. 100, 200) is described herein that is configured to optimize outcome(s) of surgical procedures through machine learning. Patterns of treatment may be recognized over the course of numerous procedures that, when implemented, lead to a successful and/or safe result for a specific patient. Such patterns of treatment can include, for example, the type(s) of surgical instrument(s) to use during the procedure, additional procedure(s) to be performed, and/or any concerns that require further monitoring. Data collected during each particular procedure, the treatment performed, and/or the outcome of the particular procedure can be stored in a data bank (e.g. remote server 113) for future analysis. The collected data can be used to bolster and/or update existing treatment recommendations. Analyzing various health statistics of a patient, such as, for example a patient's medical record and/or current vital statistics, in light of the recognized patterns can further optimize the likelihood of success of the particular procedure.
As described above in greater detail, a surgical system (e.g. 100, 200) comprises an information hub, or a surgical hub (e.g. 106, 206). The surgical hub is configured to facilitate communication between any surgical instruments used in the surgical procedure, the data source, and/or the clinician. An information hub, such as, for example, the surgical hub described herein, can store the data collected during each particular procedure. In various instances, the surgical hub can locally store data specific to the particular procedure and/or the specific patient. The surgical hub can store additional data relevant to different procedures in an external server (e.g. remove server 113).
In various examples, referring to
Example surgical instruments that are suitable for use with the surgical hub 206 are described under the heading “Surgical Instrument Hardware” in U.S. Provisional Patent Application Ser. No. 62/611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is herein incorporated by reference in its entirety. Various components of the surgical visualization system, such as the visualization system 108 are described under the heading “Advanced Imaging Acquisition Module” in U.S. Provisional Patent Application Ser. No. 62/611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is hereby incorporated by reference in its entirety.
Upon receiving an input, or data, from the data source, the surgical hub 206 analyzes the received data against a stored set of data. In various examples, the stored data set is stored in a memory 249. Such analysis is performed with the goal of optimizing an outcome of a surgical procedure. In various examples, the data storage and/or machine learning analysis can be performed locally at the surgical hub level. Additionally, or alternatively, the data storage and/or machine learning analysis can be performed at the cloud 204, for example.
In various instances, the surgical hub 206 analyzes the received data against a stored set of data using one or more untrained machine learning techniques. Using an untrained, or unsupervised, machine learning technique can allow for the determination of relationships between data pairs and/or an identification of a complication resulting from the performed surgical procedure.
The surgical hub 206 identifies commonalities in the received data and the stored data and react based on the presence or absence of such commonalities in each analyzed piece of data. Primary techniques in untrained machine learning include, for example, clustering. The goal of clustering is to create groups of data points such that points in different clusters are dissimilar while points within a cluster are similar. In other words, clustering offers protection against potential threats that are outside “normal” learned behavior. In various instances, the control circuit is configured to utilize clustering in analyzing the received data against stored data. Clustering techniques include, for example, k-means clustering and hierarchical clustering. In k-means clustering, data points are clustered into k groups. A larger k creates smaller groups with more granularity, while a smaller k means larger groups and more granularity. Each group is defined by creating a centroid for each group, wherein the cluster captures the points closest to it and adds them to the cluster. In hierarchical clustering, similar data points are grouped into clusters. In order to decide which clusters should be combined, or where a cluster should be split, a measure of dissimilarity between sets of data is required. This is achieved by use of an appropriate metric, or a measure of distance between pairs of data, and a linkage criterion which specifies the level of dissimilarity between data pairs.
Untrained machine learning techniques can develop recommendations based off of the creation of artificial neural networks. For example, a surgical imaging system, such as surgical visualization system 108, can collect data representative of structures within the surgical site. After receiving the collected structural data, the surgical hub 206 analyzes the collected data against a stored set of structural data. Techniques in untrained machine learning analyze trends and connections without considering the meaning of the data. Such analysis allows for the processor 244 to recommend identities of underlying critical structures in a surgical site by utilizing images with previously-identified areas while having no information of the parameters of the critical structures themselves.
Based on the untrained machine learning analysis, the surgical hub 206 is configured to recommend an action. The recommended action(s) can be directed toward the clinician in the form of a prompt. The analyzed data can be used to identify to a clinician that an additional procedural step is warranted, an adjunct treatment should be considered, and/or an alternative treatment is needed. The alternative treatment can comprise using a different surgical instrument and/or implementing a more robust operating program on the surgical instrument.
For example, a clinician may be performing a colorectal lower anterior resection procedure on a patient. During the surgical procedure, a surgical visualization system, such as surgical visualization system 108, may detect an over-limitation of blood supply to the region after mobilization. Once the surgical imaging system, or an alternative data source, communicates the detected over-limitation of blood supply to the surgical hub 206, the processor 244 analyzes the detected over-limitation of blood supply against previously collected data. Using an untrained machine learning technique, the processor 244 assesses commonalities between the detected over-limitation of blood supply and previously collected data. Based on the assessed commonalities, the processor 244 is configured to develop a recommendation to optimize an outcome of the surgical procedure. A possible recommendation can be, for example, use a vessel regeneration product and/or drug due to the implications of not being able to maintain an adequate blood supply to the transected tissue.
In another example, a clinician may be performing the same colorectal lower anterior resection procedure as described above. Prior to and/or during the procedure, the patient's medical records may comprise information indicating that the patient has comorbidity, or a simultaneous presence of another chronic disease or condition, and/or has previously undergone chemotherapy. Once a data source communicates the data comprised in the patient's medical records to the surgical hub 206, the processor 244 analyzes the current medical records against previously collected data.
Using an untrained machine learning technique, the processor 244 assesses commonalities between the current patient's medical records and previously collected data. Based on the assessed commonalities, the processor 244 develops a recommendation to optimize an outcome of the surgical procedure. Possible recommendations can include, for example: (1) Use a pressure-distributing absorbable adjunct stapling product in order to stress reduce the anastomosis; (2) Create a diversion to prevent bowel content from placing undo stress on the new anastomosis; and/or (3) Apply an over-sewing or fibrin/thrombin sealant to prevent leaks from occurring within the first few days of healing.
Using an untrained, or unsupervised, machine learning technique can allow for the determination of relationships between data pairs and/or the identification of a complication resulting from the performed surgical procedure. The processor 244 identifies commonalities in the received data and the stored data and reacts based on the presence or absence of such commonalities in each analyzed piece of data. Based on this analysis, the processor 244 recommends an action. The recommended action(s) can be directed toward a surgical instrument in the form of an operating program and/or parameter. In other words the recommended action(s) can be in the form of modified machine and/or device (e.g. modular devices 1a-1n, 2a-2m) settings to provide improved outcomes. For example, various surgical instruments can receive the following alterations and/or updates to the instrument's operating program: (1) surgical staplers can run slower or faster depending on factors such as tissue type, resistance felt by the knife, etc.; and (2) surgical energy devices can change the current flowing over the transection by slowly ramping up or down, etc. In various instances, the surgical hub 206 is configured to automatically update a surgical instrument's settings based on the unsupervised machine learning analysis.
While a surgical instrument's operating program can be automatically updated and/or altered with the recommendations of the surgical hub 206, the clinician can also have the ability to override the implemented recommendations. In various instances, the surgical hub 206 can prompt the clinician with the recommended alterations to the surgical instrument's operating program. The clinician is then able to accept the recommended alterations or maintain previous operating parameters. In other instances, the recommended alterations can automatically take effect, and the clinician is able to switch back to the previous operating parameters if the clinician desires.
As described above, upon receiving an input, or data, from the data source, the processor 244 of the surgical hub 206 analyzes the received data against a stored set of data. Such analysis is performed with the goal of optimizing an outcome of a surgical procedure. In various instances, the processor 244 analyzes the received data against a stored set of data using one or more trained machine learning techniques. In supervised learning, the processor 244 predicts a parameter as accurately as possible when given new examples where the inputs and outputs are unknown.
Primary techniques in trained machine learning include, for example, parametric learning and non-parametric learning. Regression, classification, and vector clustering are the two tasks involved in parametric learning. Regression predicts a continuous target variable, thereby allowing the processor 244 to estimate a value based on received input data. Continuous variables, such as, for example, a patient's height, weight, emphysema air leak rate, etc., means there are not discontinuities in the value that the predicted parameter can have. Discrete variables, on the other hand, can only take on a finite number of values—for example, the color of a staple cartridge within an end effector.
For example, a clinician may wish to predict the emphysema air leak rate based on factors such as, the stage of emphysema present in the patient, the firing speed of a surgical stapler, the force required to close the jaws of an end effector, the type and/or color of the staple cartridge within the end effector, etc. A surgical stapler is used to staple lung tissue in an emphysema patient. A suitable staple cartridge is selected based on the condition of the patient and/or the condition of the lung tissue to be stapled by the surgical stapler. Staple cartridge color may reflect the size of the surgical stapler, for example.
In various examples, the surgical hub 206 builds a model that approximates the relationship f between the above factors and corresponding emphysema air leak rate. As shown in
A first patient with stage 2 emphysema is represented by line 250710 and a second patient with stage 2 emphysema is represented by line 250715. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250710, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250715. As represented by the respective dashed lines 250710, 250715, the speed of the firing member appears to be irrelevant when the patient has stage 2 emphysema, as both patients had a good, or beneficial, outcome. Notably, the fast speed of the firing member brought the second patient 250715 closer to the threshold of acceptable outcomes of the surgical procedure.
A first patient with stage 3 emphysema is represented by line 250720 and a second patient with stage 3 emphysema is represented by line 250725. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250720, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250725. As represented by dotted line 250725, the fast advancement of the firing member in a patient with stage 3 emphysema produces unacceptable and/or detrimental outcomes to the surgical procedure, while the dotted line 250720 shows that the slow advancement of the firing member in a patient with stage 3 emphysema results in an acceptable and/or beneficial outcome to the same surgical procedure. A first patient with stage 4 emphysema is represented by line 250730 and a second patient with stage 4 emphysema is represented by line 250735. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250730, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250735. As represented by the respective dashed lines 250730, 250735, the speed of the firing member appears to be irrelevant when the patient has stage 4 emphysema, as both patients had a bad, or detrimental, outcome.
As shown in
Boxes 250760 represent measured parameters detected from individual patients whose combination resulted in a bad, or detrimental, outcome to the surgical procedure.

As described in greater detail with respect to
The previously collected data, as shown in
The surgical hub 206 to create a mathematical model 250840 based off of the previously collected data marked as the training data set 250810. The training data set is comprised of a large sample size, i.e. n=1000, to define a function. A test set 250820, 250830, or a validation set, allows the surgical hub 206 to check if the test sets 250820, 250830 fit the determined mathematical model. The test sets 250820, 250830 comprise a smaller sample size, i.e. n=50. Analysis 250835 of the test sets 250820, 250830 results in a validation model 250850 for comparison to the generated mathematical model 250840. In various instances, this gives the surgical hub 206 the opportunity to keep anticipated data and remove any unanticipated data. The ability to adjust the mathematical model 250840 allows for the fine tuning of the grouping process to populate 250855 a final mathematical model for use in data analysis. The developed model can be applied in analysis of collected data to estimate, for example, emphysema air leak rate.
As discussed above, some data points are outliers and must be removed from the data pool in order to fine tune the mathematical model. As shown in
Referring now to
Various surgical systems disclosed herein such as, for example, the surgical systems 100, 200 can utilize the algorithm 250950 of
The control circuit of the surgical system 200 is configured to analyze the received data 250954 against a stored set of data. Such analysis 250954 can be based on supervised or unsupervised learning. Such analysis 250954 can be performed within the local network of facility linked devices or could be exported to a remote location for compilation and returned to the network.
Following analysis 250954, the control circuit is configured to communicate a recommendation 250956 based on the analysis. The recommendation can be based on the identification of device interrelated impacts, patient specific impacts, and/or interaction of used devices. The recommendation can be communicated to a clinician in the form of a prompt and/or can be communicated to a particular surgical instrument in the form of updated operating parameters. In one example, the recommendations are communicated by a cloud 204 to a modular device (e.g. 1a-1n, 2a-2m) either directly, or through the surgical hub 206. In one example, the recommendations are communicated to a surgical hub 206. In any event, the recommendation can include, for example, a prompt to update a control program of the modular device or adjusting the modular device's operating parameters. In various instances, the recommendations can comprise suggestions or other procedural modifications to be indicated to the clinician. In certain instances, the recommendations include, for example, adaptation of an actuation speed, wait time, and/or other operating parameters of a modular device.
In various aspects, the machine learning systems of the present disclosure utilizes supervised learning methods to cluster data pairs into non-predefined categories based not only the outcomes, but also on the metadata context. In one aspect, supervised machine learning can be performed on cloud data from the surgical hubs (e.g. 102, 202) to find unidentified data groups. The machine learning cloud data analysis can identify, for example, regional differences in surgical and patient outcomes.
Methods of supervised learning can include, for example, parametric learning methods or non-parametric learning methods. Parametric learning methods can include, for example, regression (e.g., predicting continuous data, discrete data, or gradient descent, which is a sequential process that is used to determine the minimum of the model), classification, and vector clustering. Vector clustering is a process that, given a set of training examples, creates the capability of the system to take new examples and placing them within the grouping defined by the training examples. Vector clustering can also include margin defining, which is maximizing the margin between the groups to minimize the mis-grouping of marginal data points. Non-parametric learning methods can include, for example, decision trees and k-NN algorithms.
Data compilation methods can include, for example, singular value decomposition, normalization, and dimensionality reduction.
In various aspects, the metadata context of the data can be utilized to widen the zone between at least two groups and therefore fit the data to their groups based on the outcomes and their contributing factors. Supervised machine learning techniques can be utilized to define data groups by their outcomes and contributing factors.
The supervision methodology can be adjusted according to validation of groupings and sensitivity.
The sensitivity of the supervision methodology can be adjusted to control overlearning and threshold/probability cutoff of the machine learning model. Overlearning is the adjustability or the ratio of algorithm flexibility to bias. A highly flexible algorithm will fit all variable data into a data set, whereas a highly biased algorithm will fix a very limited set of data points into a data set. Threshold and probability cutoff is the machine learning model's tolerance of false positives versus false negatives.
In various aspects, unsupervised (or “untrained”) learning techniques can be used in order to determine relationships of data pairs from the surgical hub that contain linkages or result from a complication or morbidity, rather than the treatment step directly. In other words, machine learning can be utilized to identify non-device causes and adapt surgical hub responses accordingly.
Unsupervised learning is the process of training a machine learning model on unlabeled data. With time-based or sequential order-based learned outcomes, a program can determine the most likely to succeed next steps based on a predefined number of initial responses. These responses could be issues encountered, patient pre-operative conditions, or encountered issues in the surgical procedure. A number of unsupervised learning techniques can be used, including, for example, clustering (e.g., hierarchical clustering and k-means clustering), which provides protection against potential threats that are outside “normal” learned behavior, and unsupervised simulation of one instance of the program attempting to beat another instance of the program. The unsupervised learning techniques can also include deep learning and neural networks, which are analysis techniques that analyze trends and connections without considering the meaning of the data. Artificial neural networks can be utilized for, e.g., image processing to improve the ability to identify underlying critical structures by identifying images with the areas previously called out on the image, while having no information of the parameters of the structures themselves.
These data points could be used to identify to the user that there is an underlying cause for future evaluation, or that there is the need for additional treatment reinforcement, not because the device is not capable of proofing in a predictive fashion, but because the tissue or patient requires special care.
The result could be the identification to the surgeon that an additional procedure step is warranted, and adjunct treatment considered, or an alternative more robust product is needed. For example, during a colorectal lower anterior resection procedure, an imaging system might detect the over-limitation of blood supply to the region after mobilization as a portion of the metadata generated from the procedure. Accordingly, a vessel regeneration product or drug might be warranted due to the implications of not being able to maintain an adequate blood supply to the transected tissue.
As another example, during a colorectal lower anterior resection procedure, the co-morbidities or chemo treatments might indicate in the metadata generated from the procedure that the tissue is too easily friable. Accordingly, a pressure distributing absorbable adjunct stapling product might be warranted in order to stress reduce the anastomosis, a diversion might need to be created to prevent bowel contents from placing undo stress on the new anastomosis, and/or an oversewing or fibrin/thrombin sealant might need to be applied to insure no undo leaks occurs in the first days of healing. A surgical system 200 can be programmed to recommend the appropriate product, drug, or treatment to the physician after completion of the procedure.
Accordingly, instrument, device, or machine settings can be set according to relationships determined via unsupervised learning techniques to provide better outcomes. In at least one example, a surgical stapling instrument is updated to run slower or faster depending on tissue type, resistance to push the knife, and so on. In another example, energy devices (e.g., ultrasonic surgical instruments and electrosurgical instruments) are updated to change the applied current over the transection (i.e., slowly ramping up or down or taking other such actions). Further, in various examples, one or more of the modular device (e.g. 1a-1n, 2a-2m) of the present disclosure are programmed to automatically update their settings based on the correlations learned by a machine learning performed by the cloud-based system (e.g. 104, 204).
In some aspects, the surgeon could have the ability to override the learned settings. In one aspect, the learned settings could be the default settings. In one aspect, a modular device (e.g. 1a-1n, 2a-2m) could suggest the new settings and allow the surgeon to choose between accepting the new settings and keeping the previous defaults.
A surgical system (e.g. 100, 200) is described herein that is configured to optimize outcome(s) of surgical procedures through machine learning. Patterns of treatment may be recognized over the course of numerous procedures that, when implemented, lead to a successful and/or safe result for a specific patient. Such patterns of treatment can include, for example, the type(s) of surgical instrument(s) to use during the procedure, additional procedure(s) to be performed, and/or any concerns that require further monitoring. Data collected during each particular procedure, the treatment performed, and/or the outcome of the particular procedure can be stored in a data bank (e.g. remote server 113) for future analysis. The collected data can be used to bolster and/or update existing treatment recommendations. Analyzing various health statistics of a patient, such as, for example a patient's medical record and/or current vital statistics, in light of the recognized patterns can further optimize the likelihood of success of the particular procedure.
As described above in greater detail, a surgical system (e.g. 100, 200) comprises an information hub, or a surgical hub (e.g. 106, 206). The surgical hub is configured to facilitate communication between any surgical instruments used in the surgical procedure, the data source, and/or the clinician. An information hub, such as, for example, the surgical hub described herein, can store the data collected during each particular procedure. In various instances, the surgical hub can locally store data specific to the particular procedure and/or the specific patient. The surgical hub can store additional data relevant to different procedures in an external server (e.g. remove server 113).
In various examples, referring to
Example surgical instruments that are suitable for use with the surgical hub 206 are described under the heading “Surgical Instrument Hardware” in U.S. Provisional Patent Application Ser. No. 62/611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is herein incorporated by reference in its entirety. Various components of the surgical visualization system, such as the visualization system 108 are described under the heading “Advanced Imaging Acquisition Module” in U.S. Provisional Patent Application Ser. No. 62/611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed Dec. 28, 2017, the disclosure of which is hereby incorporated by reference in its entirety.
Upon receiving an input, or data, from the data source, the surgical hub 206 analyzes the received data against a stored set of data. In various examples, the stored data set is stored in a memory 249. Such analysis is performed with the goal of optimizing an outcome of a surgical procedure. In various examples, the data storage and/or machine learning analysis can be performed locally at the surgical hub level. Additionally, or alternatively, the data storage and/or machine learning analysis can be performed at the cloud 204, for example.
In various instances, the surgical hub 206 analyzes the received data against a stored set of data using one or more untrained machine learning techniques. Using an untrained, or unsupervised, machine learning technique can allow for the determination of relationships between data pairs and/or an identification of a complication resulting from the performed surgical procedure.
The surgical hub 206 identifies commonalities in the received data and the stored data and react based on the presence or absence of such commonalities in each analyzed piece of data. Primary techniques in untrained machine learning include, for example, clustering. The goal of clustering is to create groups of data points such that points in different clusters are dissimilar while points within a cluster are similar. In other words, clustering offers protection against potential threats that are outside “normal” learned behavior. In various instances, the control circuit is configured to utilize clustering in analyzing the received data against stored data. Clustering techniques include, for example, k-means clustering and hierarchical clustering. In k-means clustering, data points are clustered into k groups. A larger k creates smaller groups with more granularity, while a smaller k means larger groups and more granularity. Each group is defined by creating a centroid for each group, wherein the cluster captures the points closest to it and adds them to the cluster. In hierarchical clustering, similar data points are grouped into clusters. In order to decide which clusters should be combined, or where a cluster should be split, a measure of dissimilarity between sets of data is required. This is achieved by use of an appropriate metric, or a measure of distance between pairs of data, and a linkage criterion which specifies the level of dissimilarity between data pairs.
Untrained machine learning techniques can develop recommendations based off of the creation of artificial neural networks. For example, a surgical imaging system, such as surgical visualization system 108, can collect data representative of structures within the surgical site. After receiving the collected structural data, the surgical hub 206 analyzes the collected data against a stored set of structural data. Techniques in untrained machine learning analyze trends and connections without considering the meaning of the data. Such analysis allows for the processor 244 to recommend identities of underlying critical structures in a surgical site by utilizing images with previously-identified areas while having no information of the parameters of the critical structures themselves.
Based on the untrained machine learning analysis, the surgical hub 206 is configured to recommend an action. The recommended action(s) can be directed toward the clinician in the form of a prompt. The analyzed data can be used to identify to a clinician that an additional procedural step is warranted, an adjunct treatment should be considered, and/or an alternative treatment is needed. The alternative treatment can comprise using a different surgical instrument and/or implementing a more robust operating program on the surgical instrument.
For example, a clinician may be performing a colorectal lower anterior resection procedure on a patient. During the surgical procedure, a surgical visualization system, such as surgical visualization system 108, may detect an over-limitation of blood supply to the region after mobilization. Once the surgical imaging system, or an alternative data source, communicates the detected over-limitation of blood supply to the surgical hub 206, the processor 244 analyzes the detected over-limitation of blood supply against previously collected data. Using an untrained machine learning technique, the processor 244 assesses commonalities between the detected over-limitation of blood supply and previously collected data. Based on the assessed commonalities, the processor 244 is configured to develop a recommendation to optimize an outcome of the surgical procedure. A possible recommendation can be, for example, use a vessel regeneration product and/or drug due to the implications of not being able to maintain an adequate blood supply to the transected tissue.
In another example, a clinician may be performing the same colorectal lower anterior resection procedure as described above. Prior to and/or during the procedure, the patient's medical records may comprise information indicating that the patient has comorbidity, or a simultaneous presence of another chronic disease or condition, and/or has previously undergone chemotherapy. Once a data source communicates the data comprised in the patient's medical records to the surgical hub 206, the processor 244 analyzes the current medical records against previously collected data.
Using an untrained machine learning technique, the processor 244 assesses commonalities between the current patient's medical records and previously collected data. Based on the assessed commonalities, the processor 244 develops a recommendation to optimize an outcome of the surgical procedure. Possible recommendations can include, for example: (1) Use a pressure-distributing absorbable adjunct stapling product in order to stress reduce the anastomosis; (2) Create a diversion to prevent bowel content from placing undo stress on the new anastomosis; and/or (3) Apply an over-sewing or fibrin/thrombin sealant to prevent leaks from occurring within the first few days of healing.
Using an untrained, or unsupervised, machine learning technique can allow for the determination of relationships between data pairs and/or the identification of a complication resulting from the performed surgical procedure. The processor 244 identifies commonalities in the received data and the stored data and reacts based on the presence or absence of such commonalities in each analyzed piece of data. Based on this analysis, the processor 244 recommends an action. The recommended action(s) can be directed toward a surgical instrument in the form of an operating program and/or parameter. In other words the recommended action(s) can be in the form of modified machine and/or device (e.g. modular devices 1a-1n, 2a-2m) settings to provide improved outcomes. For example, various surgical instruments can receive the following alterations and/or updates to the instrument's operating program: (1) surgical staplers can run slower or faster depending on factors such as tissue type, resistance felt by the knife, etc.; and (2) surgical energy devices can change the current flowing over the transection by slowly ramping up or down, etc. In various instances, the surgical hub 206 is configured to automatically update a surgical instrument's settings based on the unsupervised machine learning analysis.
While a surgical instrument's operating program can be automatically updated and/or altered with the recommendations of the surgical hub 206, the clinician can also have the ability to override the implemented recommendations. In various instances, the surgical hub 206 can prompt the clinician with the recommended alterations to the surgical instrument's operating program. The clinician is then able to accept the recommended alterations or maintain previous operating parameters. In other instances, the recommended alterations can automatically take effect, and the clinician is able to switch back to the previous operating parameters if the clinician desires.
As described above, upon receiving an input, or data, from the data source, the processor 244 of the surgical hub 206 analyzes the received data against a stored set of data. Such analysis is performed with the goal of optimizing an outcome of a surgical procedure. In various instances, the processor 244 analyzes the received data against a stored set of data using one or more trained machine learning techniques. In supervised learning, the processor 244 predicts a parameter as accurately as possible when given new examples where the inputs and outputs are unknown.
Primary techniques in trained machine learning include, for example, parametric learning and non-parametric learning. Regression, classification, and vector clustering are the two tasks involved in parametric learning. Regression predicts a continuous target variable, thereby allowing the processor 244 to estimate a value based on received input data. Continuous variables, such as, for example, a patient's height, weight, emphysema air leak rate, etc., means there are not discontinuities in the value that the predicted parameter can have. Discrete variables, on the other hand, can only take on a finite number of values—for example, the color of a staple cartridge within an end effector.
For example, a clinician may wish to predict the emphysema air leak rate based on factors such as, the stage of emphysema present in the patient, the firing speed of a surgical stapler, the force required to close the jaws of an end effector, the type and/or color of the staple cartridge within the end effector, etc. A surgical stapler is used to staple lung tissue in an emphysema patient. A suitable staple cartridge is selected based on the condition of the patient and/or the condition of the lung tissue to be stapled by the surgical stapler. Staple cartridge color may reflect the size of the surgical stapler, for example.
In various examples, the surgical hub 206 builds a model that approximates the relationship f between the above factors and corresponding emphysema air leak rate. As shown in
A first patient with stage 2 emphysema is represented by line 250710 and a second patient with stage 2 emphysema is represented by line 250715. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250710, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250715. As represented by the respective dashed lines 250710, 250715, the speed of the firing member appears to be irrelevant when the patient has stage 2 emphysema, as both patients had a good, or beneficial, outcome. Notably, the fast speed of the firing member brought the second patient 250715 closer to the threshold of acceptable outcomes of the surgical procedure.
A first patient with stage 3 emphysema is represented by line 250720 and a second patient with stage 3 emphysema is represented by line 250725. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250720, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250725. As represented by dotted line 250725, the fast advancement of the firing member in a patient with stage 3 emphysema produces unacceptable and/or detrimental outcomes to the surgical procedure, while the dotted line 250720 shows that the slow advancement of the firing member in a patient with stage 3 emphysema results in an acceptable and/or beneficial outcome to the same surgical procedure. A first patient with stage 4 emphysema is represented by line 250730 and a second patient with stage 4 emphysema is represented by line 250735. A firing member of a surgical stapler was advanced at a slow speed during the surgical procedure of the first patient 250730, and a firing member was advanced at a fast speed during the surgical procedure of the second patient 250735. As represented by the respective dashed lines 250730, 250735, the speed of the firing member appears to be irrelevant when the patient has stage 4 emphysema, as both patients had a bad, or detrimental, outcome.
As shown in
Boxes 250760 represent measured parameters detected from individual patients whose combination resulted in a bad, or detrimental, outcome to the surgical procedure.

The previously collected data, as shown in
The surgical hub 206 to create a mathematical model 250840 based off of the previously collected data marked as the training data set 250810. The training data set is comprised of a large sample size, i.e. n=1000, to define a function. A test set 250820, 250830, or a validation set, allows the surgical hub 206 to check if the test sets 250820, 250830 fit the determined mathematical model. The test sets 250820, 250830 comprise a smaller sample size, i.e. n=50. Analysis 250835 of the test sets 250820, 250830 results in a validation model 250850 for comparison to the generated mathematical model 250840. In various instances, this gives the surgical hub 206 the opportunity to keep anticipated data and remove any unanticipated data. The ability to adjust the mathematical model 250840 allows for the fine tuning of the grouping process to populate 250855 a final mathematical model for use in data analysis.

As discussed above, some data points are outliers and must be removed from the data pool in order to fine tune the mathematical model. As shown in
Referring now to
Various surgical systems disclosed herein such as, for example, the surgical systems 100, 200 can utilize the algorithm 250950 of
The control circuit of the surgical system 200 is configured to analyze the received data 250954 against a stored set of data. Such analysis 250954 can be based on supervised or unsupervised learning. Such analysis 250954 can be performed within the local network of facility linked devices or could be exported to a remote location for compilation and returned to the network.
Following analysis 250954, the control circuit is configured to communicate a recommendation 250956 based on the analysis. The recommendation can be based on the identification of device interrelated impacts, patient specific impacts, and/or interaction of used devices. The recommendation can be communicated to a clinician in the form of a prompt and/or can be communicated to a particular surgical instrument in the form of updated operating parameters. In one example, the recommendations are communicated by a cloud 204 to a modular device (e.g. 1a-1n, 2a-2m) either directly, or through the surgical hub 206. In one example, the recommendations are communicated to a surgical hub 206. In any event, the recommendation can include, for example, a prompt to update a control program of the modular device or adjusting the modular device's operating parameters. In various instances, the recommendations can comprise suggestions or other procedural modifications to be indicated to the clinician. In certain instances, the recommendations include, for example, adaptation of an actuation speed, wait time, and/or other operating parameters of a modular device.
In various examples, activation of a surgical hub in an operating room signifies that a surgical procedure has started and, is underway, which causes the surgical hub to detect a preoperative status 206503. Additional data sources could also be relied upon, alone or in combination, in detecting the preoperative status 206503. For example, receiving 5206 a scan of a patient band via a scanner that is communicably connected to the surgical hub 5104 can indicate a preoperative status 206503. Additionally, or alternatively, receiving 5210 data from a patient monitoring device such as, for example, an EKG can indicate a preoperative status 206503.
As described above, the surgical hub 5104 can infer that the patient is under anesthesia based on data from the modular devices and/or patient monitoring devices, including EKG data, blood pressure data, ventilator data, or combinations thereof, for example. Upon completion of the sixth step 5212, the pre-operative portion of the lung segmentectomy procedure is completed. Accordingly, receiving such data can indicate a transition from the preoperative status 206503 to the intraoperative status 206505.
In one aspect, the surgical hub controls can be based on the awareness of whether or not a procedure is in process (i.e., whether a surgical procedure is currently being performed in connection with the particular surgical hub). Accordingly, the surgical hub controls can be based on the situation in which it senses itself.
The process 206500 further includes adjusting 206504 a response to a sensed parameter based on the determined situational parameter or progress status of the surgical procedure. In at least one example, as illustrated in
As illustrated in
The mode 206524 is more restrictive than the mode 206526, and the mode 206526 is more restrictive than the mode 206528. This arrangement is designed to take into consideration a user error in the form of inadvertent commands, for example. Before the surgical procedure starts, the mode 206524 only permits access to previous procedure data, and a limited interaction with a cloud-based system 104, 204, for example. During the preoperative steps, but before surgery is begun, the mode 206526 provides a less restrictive interface that permits a user to access and/or configure various parameters and/or controls without being able to use or activate such controls. In the least restrictive mode 206528, which is only available during surgery, the user is allowed to use or activate controls of certain modular devices depending on the surgical step being performed, as illustrated in
A surgical hub can make inferences about events that are occurring during the course of a surgical procedure and then respond accordingly.
As described above, data from various data sources can be analyzed, for example by a surgical hub 5104, to determine 206523 whether a surgical procedure is underway. Patient data 206532 from one or more patient monitoring devices can be used to determine 206531 whether a patient is present in the operating room. Additionally, or alternatively, surgical staff data 206534 from a surgical staff detection device can be used to determine 206533 whether the necessary supporting staff for the surgical procedure is present in the operating room. Additionally, or alternatively, modular device data 206536 from one or more modular devices can be used to determine 206535 whether the equipment necessary for performing the surgical procedure is present in the operating room. Additionally, or alternatively, hospital data 206538 from one or more hospital databases can be used to determine 206537 the type of procedure being performed, for example.
The determinations at 206531, 206533, 206535, 206537 can be used separately, or in any suitable combination, to determine 206523 whether a surgical procedure is underway. In various examples, each of the determinations at 206531, 206533, 206535, 206537 can be assigned a predetermined value when achieved. The summation of all the values can then be compared to a predetermined threshold to determine 206523 whether the surgical procedure is underway. In certain examples, a surgical hub 5104 must achieve each of the determinations at 206531, 206533, 206535, 206537 before determining 206523 that a surgical procedure is underway.

Furthermore, surgical staff data 206534 from a surgical staff detection device can be analyzed to determine the identity of the individuals in the operating room and/or where they are located with respect to the patient. For example, surgical staff data 206534 can be analyzed to assess whether a surgeon is standing in close proximity to the patient. For example, a surgical hub can receive a unique identifier from, for example, a scanner for scanning surgical staff wristbands encoding the unique identifier associated with each member of the surgical staff patient when they enters the operating theater. Other techniques for identifying a patient and/or a surgical staff are disclosed in U.S. Provisional Application No. 62/659,900, titled METHOD OF HUB COMMUNICATION, filed on Apr. 19, 2018, which is hereby incorporated by reference herein in its entirety.
Further to the above, the modular device data 206536 may include identification data for determining what devices are present in the operating room and/or what devices are active and/or paired with a surgical hub, for example. In one exemplification, a surgical hub can be configured to compare the list of items for a procedure (scanned by the scanner, for example) and/or a list of devices paired with the surgical hub to a recommended or anticipated manifest of items and/or devices for the given surgical procedure to determine 206535 whether the necessary equipment for the surgical are present in the operating room.
Further to the above, the hospital data 206538 may include EMR data that can be pulled from an EMR database containing patient records. Based on select patient data in the EMR, a surgical hub can determine the type of procedure to be performed, for example, which is helpful in assessing whether the surgical procedure is underway. In various examples, it is contemplated that other 206539 data can be received and analyzed by a surgical hub to determine 206523 whether a surgical procedure is underway, in accordance with the process 206520, for example.
As described above, the process 206500 includes adjusting 206504 a response to a sensed parameter based on a determined situational parameter or progress status of a surgical procedure. In at least one example, as illustrated in FIG. 44, the sensed parameter can be detecting 206552 a security threat. In other examples, the sensed parameter can be detecting 206554 a surgeon. In other examples, the sensed parameter can be detecting 20559 an instrument fault such as, for example, a modular device.
Further to the above, responding to a detected 206552 security threat depends on whether surgery is progress, which can be determined 206525, as described above in connection with
In various examples, the isolated operation mode 206553 comprises interrupting communications with external systems such as, for example, the cloud-based system 104, 204. In certain examples, the communications interruption excludes local communications within an operating room such as, for example, instrument-to-instrument communications, instrument-to-surgical hub 106, 206 communications, and/or remote controller-to-instrument communications.

In various instances, a surgical hub 5104 determines the present step of an ongoing surgery based on data received 206502 (
In various examples, the surgical hub 5104 may store a database of various surgeries, the identity and order of the surgical steps pertaining to each of the surgeries, and/or the identity and/or usage or activation frequency of the modular surgical devices to be used in each of the surgical steps. In such examples, a user input selecting or identifying the surgery to be performed may be all that is needed for the surgical hub 5104 to identify the surgical steps and modular surgical devices associated with the surgery to be performed.
In other examples, the surgical hub 5104 deduces the type of surgery to be performed, and/or its corresponding surgical steps, by detecting modular surgical devices that are in close proximity to the patient and/or are within the operating room. Additionally, or alternatively, the surgical hub 5104 may determine the type of surgery to be performed, and/or its corresponding surgical steps, from a received 206502 patient EMR, for example.
In various examples, the surgical hub 5104 could ignore hand piece activation based on depression of the buttons on the handle of a modular energy device if the surgical hub 5104 is aware the generator, surgical hub 5104, and/or the modular energy device are not in an active surgery. This can reduce inadvertent activation of devices. Furthermore, this could operate on a finer control level as well: If the surgical hub 5104 determines that the modular energy device is not inside the patient or in contact with a patient's tissue by sensing continuity or the linking of the return path of the return pad, the activation of the modular energy device could be ignored. This could even be used relative to patient proximity in aspects where the system is capable of instrument tracking.
In one aspect, the surgical hub controls can be programmed such that fault detection during a surgery triggers a different response than fault detection does before or after a surgery. Accordingly, the severity of the surgical hub's response to faults can be based on its awareness of its use status.
In one aspect, a detected fault severity response can be based on whether the surgical hub 5104 believes the device is unsafe or could be put into a limp mode because it is currently in-use. For example, if a counterfeit cartridge reload is used in a procedure, the user is warned 206605, but the product is allowed to be used with surgeon override if the modular device is already in-use. As opposed to a reload being installed at the beginning of a procedure, for example in the pre-operative stage, at which point the severity it senses might be a higher level and it may lock-out the use of that combination of products. As another example, the number of uses flag can be treated in one manner before and after the procedure, as opposed to it being triggered during a procedure. The surgical hub's inclination to lockout a device that has been reused too many times before a procedure can be overridden to allow the device to continue if the trigger is activated while in a procedure. The inclination to lockout the device can then be restored once the procedure is complete.
In one aspect, security responses in certain situations could be substantially more restrictive based on the situational awareness of the surgical hub 5104. Accordingly, surgical hub's security response can be based on its perceived need for secure use. For example, the protective reaction to a system attack might be elevated if the system is aware that it is in-use. As another example, the protective response to an attack might be escalated if surgical hubs are already aware they are under attack in other locations. As yet another example, remote access for controlling aspects of the modules within the surgical hub 5104 could be limited when the surgical hub is in use in a procedure. In one implementation, the external control aspects of the modular devices could be disabled when local control is established. In another implementation, when remote access is requested and a procedure is in process or there is a sensed use by a local user, the surgical hub might request confirmation locally for permission before granting permission for remote control of the system or function.
In one aspect, the configuration and responses of the surgical hub 5104 could be altered based on the user the surgical hub senses is in-use. Accordingly, the surgical hubs can be programmed to automatically re-configure based on sensed users. For example, the default configuration of an attached device and the controls of the device could be adjusted based on the user the surgical hub senses is using the device. If a specific surgeon doing a specific procedure always tends to use a device or its control in a repeatable manner, the surgical hub could automatically configure the device for the user as its learns his or her behavior. As another example, the surgical hub 5104 can learn the behaviors of the users it works with. This could even be with a network of hubs, which could each communicate preferences, setups, and alterations in device setup for specific users. Accordingly, when a specific user is sensed, either by login or another technique, the surgical hub 5104 could then start configuring the systems based on previous uses by the user in question.
In various aspects, a modular device 5102 such as, for example, a surgical instrument may interact with other modular devices 5102 and/or surgical hubs 5104. The interaction may occur before, during, and/or after a surgical procedure commences. For example, the modular device 5102 may receive a firmware update from a surgical hub 5104 before the surgical procedure. In another example, the modular device 5102 may receive commands from a remote controller during a surgical procedure. In yet another example, the modular device 5102 may transmit usage data to a surgical hub 5104 regarding a surgical procedure after completion of the surgical procedure. Unauthorized interactions between a modular device 5102 and other modular devices 5102 and/or surgical hubs 5104 can interfere with the proper operation of such devices and systems.
Ensuring a secure interaction between a modular device 5102 and other modular devices 5102 and/or surgical hubs 5104 can be achieved by generating an appropriate response to an unauthorized interaction. In various aspects, the response of a modular device 5102 to a potential security violation or unauthorized interaction can be adjusted based on situational awareness. In some situations, the response of a modular device 5102 to a potential security violation or unauthorized interaction can be based on situational awareness that the modular device 5102 itself is attacked, instead of a surgical hub 5104, for example.
In one aspect, a wirelessly pairable modular device 5102 can be programmed for detection and escalation of security responses in response to numerous or increasing severity threats. For example, the first response to a first violation results in a minor reaction and a second response to a second serial violation results in an escalated response. In another aspect, the escalated response could be termination of communication and/or autonomous usage only of the instrument.
In one aspect, a surgical instrument can be programmed to implement an escalation protocol to react according to the number or invasiveness of a security violation. Accordingly, a surgical instrument can be programmed to escalate security response in response to increasing threats. For example, a wireless device which pairs to another device or surgical hub and senses a first unauthorized or unauthentic interaction causes the device to execute a minor response (e.g., warn the user or raise the threat warning). When the device senses multiple additional issues or the severity of the additional issue is higher, the device's second response can be escalated much greater than the first response (e.g., end communication and only operate autonomously or only accept fully authenticated and encrypted requests). As another example, a device can execute a security response when communication interaction appears probing after already flagging an unauthentic handshake.

In various examples, any suitable wireless communication can be employed by the communication module 206622 including, for example, Bluetooth wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). The communication module 206622 may employ anyone of a number of wireless or wired communication standards or protocols, including but not limited to Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20, long-term evolution (LTE), and Ev-DO, HSPA+, HSDPA+, HSUPA+, EDGE, GSM, GPRS, CDMA, TDMA, DECT, and Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. In at least one example, the communication module 206622 may employ an Air Titan-Bluetooth.
In at least one example, a pairing attempt with the communication module 205522 by an unauthorized modular device or surgical hub is detected 206612. In response, the control circuit 206624 may cause 206614 the user interface 206624 to issue a warning or an alert, which can a visual and/or an audible alert. Furthermore, the modular device 5102 may store 206616 a record of the first pairing attempt in a memory unit of the control circuit 206624, for example.
If, however, a second pairing attempt by an unauthorized modular device or surgical hub is detected 206618, the control circuit 206624 may cause 206620 a second response, escalated from the first response, to be generated. For example, the control circuit 206624 may cause the communication module 206622 to terminate all external communications and/or may cause an autonomous operation mode to be activated.
In at least one example, the modular device 5102 is a surgical stapler, and the first security violation or unauthorized interaction involves loading a spent, or previously used, staple cartridge onto the surgical stapler. Detecting 206612 the spent staple cartridge can be achieved by one or more sensors and/or by interrogating a chip of the staple cartridge to assess whether its identification number is associated with a new or unspent staple cartridge. Once a first spent staple cartridge is detected 206612, the control circuit 206624 causes 206614 the user interface 206626 to issue to issue a warning or an alert, which can a visual and/or an audible alert. The alert may include instructions to remove the spent staple cartridge.
Further to the above, the modular device 5102 may store 206616 a record of the spent staple cartridge in a memory unit of the control circuit 206624, for example. If, however, the control circuit 206624 detects 206618 that the same spent staple cartridge, or another spent staple cartridge, has been loaded onto the surgical stapler, a more escalated response can be generated by the control circuit 206624. For example, the control circuit 206624 may cause the surgical stapler to enter a permanent lockout, preventing the surgical stapler from further usage. The control circuit 206624 may also report the incident to a surgical hub, for example. Other suitable escalated responses are contemplated by the present disclosure.
In various aspects, a surgical hub can be configured to provide surgical hub 5104 feedback to a user. The feedback could be adjusted based on a connotation resulting from a different connotation. In one aspect, a surgical hub 5104 can be programmed to provide interactive feedback to the user that enables adjustment of a device or display based on presence of an actionable aspect of the task at hand for the user. In one aspect, the interactive feedback could include visualization improvements identified by the surgical hub/visualization module that could provide better or more complete imaging of the surgical site. In one aspect, the interactive feedback could include an alternate imaging overlay demonstrating how a device could be better articulated when a device is placed in an inopportune location.
In one aspect, the surgical hub or displays could be affected based on the sensing of an action context for the user. Accordingly, display adjustments could be based on the surgical hub's awareness of actionable context.
In various aspects, a monopolar return pad can be utilized in additional applications beyond simply a return path for monopolar energy. In one aspect, the radiative resistance measurement can indicate patient position changes during surgery.
In one aspect, an interrogation circuit can constantly monitor the RF radiative resistance of the pad at high frequency. This allows for a determination of the base radiative resistance, which can then be utilized in combination with the situational awareness of the surgical hub to provide an indication of when the patient is on the pad. For example, a patient's shoulder placed on a portion of the pad may change a measure of radiative resistance in at least part of the pad. This may be compared against the base radiative resistance, and in some cases the comparison may be examined using situational awareness to determine more specifically if a particular body part or location of the body is placed on the pad. In some cases, the radiative resistance may be measurable in different places on the pad, and so different parts of the pad may provide different readings, based on if a body part is on that location of the pad. These different measurements may then be used to provide a more illustrative picture of where the body—and what parts of the body—is placed on the pad overall. Once this is determined, the quality of the patient to monopolar return pad coupling can be determined.
For additional clues or information, patients or other RF conductive elements will cause parasitic loading of the capacitively coupled pad when the pad is driven by a source with a frequency or frequencies that have wavelengths a significant fraction of the pad's transmitting antenna characteristics and resonances. Accordingly, in one aspect, this loading can be measured to track the changes during patient placement and the surgical procedure. The changes in the parasitic loading can indicate that something about the patient or the local environment has changed. For example, the patient may be maneuvered to a different spot on the pad, or may be turned to have different parts of the body on the pad, such as turned on the patient's side, or have an arm raised. In other cases, the patient may unintentionally be moved off the pad, the patient may react physiologically to the RF energy such that the capactive load and/or radiative resistance changes, or the patient may experience a sudden change in response to the surgery that bears out in the capacitive coupling. This information can be used in conjunction with the situational awareness of the surgical hub to determine if any action or warning needs to take place. Further, a “trap” circuit may be employed to keep the electrosurgical generator out of the circuit that is being measured for radiative resistance.
In another aspect, vector network analysis can be utilized to measure antenna input impedance as a function of frequency.
In another aspect, the H-field (i.e., magnetic field intensity) can be measured in multiple (e.g., two) orthogonal directions to get a sense of what loading the patient is providing. These may provide additional pieces of information that can be factored into situational awareness. For example, the combination of radiative resistance measurements, capacitive coupling measurements, antenna input impedance and H-field measurements may create a particular signature for a type of surgery or patient condition, such that situational awareness as employed by the medical hub and/or the cloud system may incorporate the particular pattern to help determine if the course of the surgery is progressing as expected or if something wrong is occurring.
In one aspect, the radiative resistance measurement can be used in conjunction with nerve stimulation to detect patient movement that is in synchrony with the stimulation signal, as disclosed in Wikipedia contributors, “Radiation Resistance,” Wikipedia, the Free Encyclopedia, last revision Oct. 7, 2017, available at wikipedia.org/wiki/Radiation_resistance. Situational awareness may incorporate these readings as well, similar to the descriptions above.
In various aspects, the surgical system can be configured for automatic tuning and compensation for variations in capacitance of the monopolar return pad-to-patient coupling. In various aspects, the system can compensate for variations in coupling capacitance by adjusting the power of the attached devices or adjusting the frequency.
In one aspect, the control system can include compensating networks capable of adjusting the power of the attached devices based on the detected connection. Accordingly, the networks could compensate for changes in capacitance of the monopolar return pad.
In the first graph 209305, some example readings may include a threshold line 209310 for maximum power of the generator and a threshold line 209315 for a user setting maximum power of the generator. The plot 204320 therefore reflects the actual applied power of the monopolar probe, and it can be seen that the applied power reaches a maximum at the user setting threshold 209315. The extra plot 209325 reflects the theoretical or potential maximum power of the monopolar probe that could have been applied.
In the second graph 209330, the plot 209335 represents a measure of resistance at the return pad, expressed in ohms. The resistance may be an expression of how connected the patient is to the return pad, where the higher resistance measured generally indicates that the patient is not as well connected to the return pad.
As shown, the markings at t1, t2, t3, t4, t5, and t6 show changes in the state of the generator and the patient that are reflected in both graphs but in different ways. For example, at t1, the resistance drops as the power of the monopolar probe is applied to the patient, closing the circuit and reflecting that the patient is aptly connected to the pad. When power is increased at t2 and ends at t3, the resistance drops even further, which is expected. However, at t4, something may have happened to the patient and the patient is somehow not sufficiently connected to the pad, reflecting an sudden increase in resistance. Correspondingly, the power from the generator may be turned off and/or the probe disconnected from the patient. This is represented by the period tw. During this time, steps may be taken to verify that the patient is fine and that any recovery steps are taken before resuming. From t5 to t6, the generator power may be incrementally increased and verified that the patient is duly connected to the return pad again. After that, the process resumes as intended as reflected in the rest of the graphs.
This kind of combined information may be used to make determinations about the position of the patient on the pad, and may be incorporated into kinds of patterns used by the situational awareness of the medical hub and/or the cloud system for future surgeries or operations of a similar nature. Thus, situational awareness may be applied to flag patterns of information that were consistent or even identical to past anomalous occurrences that may have looked like some of the problem situations described in
In another aspect, a control system can compensate for variations in capacitance of the monopolar return pad-to-patient coupling by changing frequency. Accordingly, the control system can change frequency to compensate for capacitance in the monopolar return pad.
In one aspect, a frequency agile generator can constantly sweep the output frequency through a predefined range, either in combination with a fixed inductor in series with the return pad or with a peaking compensating network to peak the power output, as described above. The reactance of the capacitor formed by the patient and the pad will change based on the contact the patient is making with the pad and this will compensate for those changes.
In another aspect, a controls system can adjust output frequency of the generator to seek the peak power output when using a reactive impedance (e.g., capacitive) pad.
In various aspects, a control system can provide feedback regarding the contact/return pad quality and indicate to the OR personnel of the current efficiency of the return pad. The medical hub may provide an indication, via a graphical user interface or one or more auditory signals, of the connectivity of the patient to the return pad or if there is some disconnect. Some example methods for making this determination are described above.
In various aspects, the functionality of the generator and/or monopolar return pad can be integrated with nerve stimulation indications.
In one aspect, the surgical hub can be configured to modulate the energy (e.g., the energy applied by a generator to a monopolar electrosurgical instrument) based on nerve mapping and situational awareness. In addition to warning the surgeon when they're close to a nerve, the cutting energy (e.g., electrosurgical, ultrasonic, or the like) can be reduced as the surgeon cuts closer to a surgical hub-identified nerve structure. For example, energy can be stopped when the surgeon is about to damage a hub-identified nerve structure. In one aspect, the surgeon is required (e.g., by the surgical hub) to make a conscious decision to override a warning and a drop in power or inability to deliver power based on the surgical hub's awareness of a nerve mapping. Accordingly, modulation of energy by the surgical hub can be based on nerve mapping and situational awareness.
Similarly,
In various aspects, adjustable autonomous control programs can contain limits on surgical instrument algorithms. In one aspect, a powered surgical instrument 208100 (
In one aspect, the adjustable control algorithm controls at least one function of the end effector 208109. In one aspect, the adjustability is dependent on at least one sensed parameter. In one aspect, the sensed parameter includes a historical dataset of previous uses of the surgical instrument 208100 by the surgeon, in the facility, in the region, or by the user base at large. In one aspect, the limit of the adjustment is predefined by the surgical instrument 208100 and/or a surgical hub (e.g. 102, 202). In one aspect, the limit is an overall maximum threshold. In one aspect, the limit is a per use adjustment. In one aspect, the limit is based on uses by a specific user, in a specific facility or in a specific region.
In one aspect, a control program can limit control-program learning adjustments. For example, in a qualified aggregation an event or behavior could have to pass a check to determine if it is going to be allowed to affect long term behavior of a particular surgical instrument 208100, or a class of surgical instrument 208100, for example. A control program executed by a surgical instrument 208100, or a surgical hub (e.g. 102, 202), may factor out individualized or one-time failures (e.g., a damaged or mis-inserted cartridge due to a non-repeatable error) that have a minimal effect on the behavior of the control program. In other words, the data associated with the individualized error may or may not be transmitted to a surgical hub (e.g. 102, 202) and/or main database depending on the nature of the individualized error. Even, however, if it is transferred, the individualized error could be excluded from the aggregated database used to affect long term behavior of the surgical instrument 208100 as a means to prevent or detect future flaws of the surgical instrument 208100.
As another example of qualified aggregation, the weighted effect of a behavior could be used to influence the amount of adjustment (e.g., a “class 0” defect resulting in a patient injury could have a greater influence as a single event on device performance than a number, e.g., 10×, of minor variations).
In one aspect, a control program can limit control program learning adjustments across a series of parameters. For example, learning adjustments can be limited to a maximum adjustment of the control algorithm over a given time interval (e.g., +10% over a week, a month, or another interval). This would prevent different behaviors from a new user, rotation of OR staff, or other individuals, from dramatically shifting the instrument behavior for all other users (especially if, e.g., some other users are on vacation, not working over a weekend, or are otherwise not actively using the instruments for a period of time).
As another example, maximum and minimum total limits on a performance behavior can be applied for a given user. This could have a lifetime cumulative effect or a maximum adjustment for a given BIOS or control program version. Each time a control program is updated, the adjustment could be transferred over or it could be “reset” to a nominal target value and the system will have to re-learn the adjustment, for example. This would allow the system to benefit from improved control programs, without requiring that the control program re-learn the same adjustment if the program operates differently. As another example, users could be able to temporarily use other users' settings, if desired, while not having the ability to alter those settings.
In one aspect, a control program could set a cap or a maximum on the number of adjustments to the control program per procedural use. This would minimize what could appear as dramatic alterations in behavior from one use to the next. Further, this could also be factored as per use per user and therefore have different behaviors for different users and minimize the adjustments of the device performance from one user to the next.
In one aspect, a control program could be programmed to implement a predefined adjustability envelope. In this aspect, adaptive algorithms and techniques could be implemented to locally adjust (i.e., adjust a control program of a given surgical hub (e.g. 102, 202) or the control programs of a local network of surgical hubs of, e.g., a single facility) overall control schemes. The adjustment methods can be implemented by machine learning, e.g., as a neural network, for updating/controlling attached devices' algorithms.
In at least one instance, a GUI for controlling various device parameters, such as those parameters described above, is disclosed. The GUI can be displayed on, e.g., the device being controlled and/or a surgical hub (e.g. 102, 202) to which the device is connected. The GUI allows users to select settings for a particular surgeon (e.g., “Dr. Smith” or “Dr. Jones”) per device type (e.g., staplers, energy devices, scopes, and so on) per action type (e.g., clamping, firing, or articulating settings for staplers). Different settings for the devices can be learned over time as users are more experienced in using the devices.
In one aspect, the control programs can provide an overriding capability to allow the user to default the device to the nominal or manufacture's suggested value of a device performance. For example, there could be an indication of the device's current learned parameters and allow the user to determine if they want to utilize this customized performance. As another example, the user could have the ability to select an override of an adjusted parameter. This could occur before a device is used, at the beginning or a procedure, or even during an actuation. As another example, the control programs could allow the user to reset the device to a non-adjusted state or even disable the ability for the parameter to be adjusted over time due to measured performance in the future.
In one aspect, a device could identify a user usage or behavior and determine a performance parameter adjustment to improve outcomes for that behavior. It could then in a later use detect the same behavior or usage, but because it is a different user, either limit the application of the adjustment or request the user confirm the use of the improvement before it was used. For example, if thicker than indicated tissue and an uneven distribution of the tissue with it skewing to the tissue stop end of the anvil is detected, the control program could adjust for these variables for by slowing the firing I-beam advancement in the beginning of the stroke and increasing the displayed stabilization wait period. Accordingly, if this same irregular tissue stuffing of the jaws is detected at a later time, but it appears to the instrument that the user is different than the first user, the instrument could ask if the user wants to use the new performance program or the standard program rather than merely adjust the parameters automatically as it would for the first user using the device in a subsequent procedure.
In at least one embodiment, a surgical instrument system includes a surgical end effector, such as surgical end effector 208109, for example, or surgical instrument such as those disclosed herein (e.g. 208100), for example, configured to deliver at least one end effector function to a patient and a control circuit, such as the control circuit 208103, for example, configured to operate the surgical end effector and/or the function of the surgical end effector 208109. Function(s) of the end effector 208109 can be actuated by a surgical robot and/or by way of a handheld instrument handle, for example. The handheld instrument handles may be manually operated by a clinician. The end effectors attached to surgical robot may be manually operated by a clinician operating the surgical robot and/or automatically operated by a control circuit of the surgical robot, for example. Functions of an end effector may include firing staples, for example, which may include cutting tissue and/or deploying staples in a surgical stapling end effector. Another end effector function may include clamping tissue with a surgical stapling end effector. Yet another example of an end effector function may include energizing tissue with a surgical energy device. It should be appreciated that any suitable end effector functions can be used with the surgical systems described herein.
The control circuits of such surgical systems can include adaptive control programs configured to control the end effector function and adapt itself over time to better accommodate subsequent uses of the end effector function(s) and/or the surgical instrument systems. Such adaptive control programs can utilize various types of information to automatically adjust and/or adapt the control program of the end effector function. For example, the adaptive control programs can be directly based on inputs including parameters sensed within an end effector, such as end effector 208109, for example, itself, within a patient, and/or within a surgical suite. The adaptive control programs can also be based on inputs from a surgical hub (e.g. 102, 202) for example. Machine learning can be used to analyze the inputs and make adjustments to the adaptive control program in an attempt to provide better end results of the end effector function for each subsequent use.
In at least one instance, the adaptiveness of the control program is based on a locally-sensed parameter within the end effector, such as end effector 208109, for example. For example, the load on a tissue-cutting knife or firing member 208111 applied by tissue and/or other aspects of the system, in a surgical stapling end effector can be measured within the end effector 208109. Information about the load on the tissue-cutting knife can be fed to the control circuit 208103 so that the control circuit 208103 can adjust the control program of the tissue-cutting knife automatically. For example, if the load is monitored and becomes increasingly high during a firing sequence, the adaptive control program may predict that the next firing sequence will include a similar load profile and, in at least one instance, the adaptive control program can automatically slow the firing speed of the tissue-cutting knife for the next firing sequence to prevent the tissue-cutting knife from becoming jammed.
In at least one instance, the adaptiveness of the control program is based on information collected over a period of time. Further to the above, the adaptiveness of the control program can be based on specific information collected over time. For example, the adaptiveness may only be based on data collected while a certain surgeon was using the device. In at least one instance, the adaptiveness may only be based on data collected during use on a specific patient, during use in a specific operating room, during use in a specific region of the country, and/or during use on specific types of procedures. Any suitable groupings of data can be used for control program adaptiveness. In at least one instance, multiple groupings of data are used cooperatively and the adaptiveness of the control program is based on the multiple groupings of data.
In systems utilizing adaptive control programs, it may be advantageous to restrict the adaptiveness of the control program itself. Placing limits, automatically based on locally-sensed parameters, for example, and/or manually based on direct input from a surgeon, for example, on the adaptiveness of the control program can prevent undesirable adaptive adjustments to the control program. Further to the above, such restrictions and/or limitations placed on the adaptive control programs, whether applied automatically and/or applied manually can provide more information for machine learning aspects of the control circuit to better operate the end effector functions in subsequent uses. Such limitations may be put in place by an adaptive-limiting program, for example.
Referring again to the tissue-cutting knife example discussed above, a clinician may be aware that the adaptive control program is going to slow down the firing speed of the tissue-cutting knife for a subsequent firing sequence; however, in such an instance, the clinician may not want the firing speed of the tissue-cutting knife to slow down for the next firing sequence. The clinician may want a limit automatically placed on the adaptive control program controlling the firing function of the end effector, such as end effector 208109, for example. In at least one instance, the clinician may want to manually place a limit on the adaptiveness of the control program controlling the firing function. In the discussed example, the clinician may want define a slowest-possible firing speed value that the adaptive control program is permitted to automatically slow to. In such an instance, after such a restriction and/or limitation is set in place, the adaptive control program may not be permitted to adjust the firing speed of the tissue-cutting knife to a speed that would fall below the defined slowest-possible firing speed. Restrictions and/or limitations may be set during a procedure, before a procedure, and/or after a procedure. In at least one instance, the clinician may be made aware by way of a display or audible alert of the adaptiveness of the control program in real time to allow the clinician to make real-time adjustments to the adaptiveness of the control program.
In at least one instance, the adaptive adjustments made by the control program can have bounds placed on them. For example, a control circuit, such as the control circuit 208103, for example, could analyze behavior of an end effector function to determine whether or not that the behavior would affect the adaptiveness of the control program thereby affecting the long term behavior of the end effector, such as end effector 208109, for example. In such an instance, one-time inadvertent and/or preventable failures of the end effector 208109 could be ruled out so that that the one-time failure is not factored into the adaptiveness of the control program of the end effector 208109. For example, if a staple cartridge is improperly loaded into a surgical stapling end effector and firing is attempted, this irregular load sensed due to the improperly loaded staple cartridge can be treated as outlier and not factored into the adaptiveness of the control program of the end effector. In at least one instance, such a misfire could still be factored in to the adaptiveness of the control program but not with the same weight as a tissue-jam incident resembling a similar load level as a misfired end effector would. In other words, it may be desirable to not completely ignore an improperly loaded cartridge misfire event and, rather, to apply it to the adaptiveness of a control program in a manner that would be less aggressive than a tissue-jam incident where a cartridge was properly loaded. At any rate, outlier events or behavior can be excluded from the aggregated database of usage such that the outlier events do not affect long term behavior of the adaptive control program.
In at least one instance, certain events, such as the improperly-loaded cartridge misfire event discussed above could be given different weight values when determining the amount of influence such an event would have on the adaptiveness of the control program. For example, a misfire due to an improperly loaded staple cartridge may be given considerably less weight providing considerably less influence to the adaptiveness of the control program than a complete tissue jam incident resulting after a properly assembled cartridge firing. In such an instance, the type of tissue may have caused the complete tissue jam incident which may be much more desirable to have influence the adaptiveness of the control program in case the clinician and the end effector encounters that type of tissue again. On the same hand, a clinician may not want the adaptive control program adjusting itself based on user error of an improperly loaded cartridge and/or misuse of the instrument.
During normal operation and assuming no misuse of the end effector, such as end effector 208109, for example, an event that causes patient harm and/or injury could be given a much higher weight and thus influence the adaptiveness of the control program greater than an event that causes little to no patient harm and/or injury to a patient.
In at least one instance, bounding of the adaptive control program can occur across a series of parameters. For example, a control circuit, such as the control circuit 208103, for example, can permit only a percentage of adjustment to the control program over a certain period of time. For example, an adaptive firing control program for a surgical stapling end effector, such as end effector 208109, for example, may be limited to adjusting the firing speed of the control program±10% of the firing speed over a week of time. Any suitable percentage restriction can be employed with any suitable time interval. Such an arrangement may eliminate drastic adaptiveness during a certain time period. For example, an end effector may possibly undergo a break-in period and have some abnormal sequence during the beginning of its usable life. Thus, it may be desirable in such an instance to limit the adaptiveness of the control program for that end effector over its break-in period. Another advantage may include eliminating drastic adaptiveness across multiple users which have different operating behaviors.
In at least one instance, maximum and minimum program limits can be specific to a given user. In such a scenario, the user may be able to set these for a lifetime cumulative effect. In at least one instance, the user may be able to select maximum and minimum program limits specific to another user. In at least one instance, where the user is using limits specific to another user, the user may not be able to adjust the limits specific to another user nor will those limits be able to be adjusted by the adaptive control program because the user specific to those limits is not employing them.
In at least one instance, limits placed on adaptive control programs could be transferred into a database and/or hub (e.g. 102, 202) and that control program would be reset to a nominal target value. In such an instance, limits may need to be re-learned and/or re-adjusted. In another instance, a surgeon can be given the option to reset the limits to the nominal value or to set the control program where the surgeon left off at the end of the last use. This would allow systems to benefit from improved control programs and perhaps not need the same adjustment if the program operates differently.
In at least one instance, limits placed on adaptive control programs can be based on a per-use basis. In at least one instance, the adaptiveness of the control program can be isolated to a single procedure and/or a lifetime use of the specific end effector which the control program is controlling.
In at least one instance, adaptive control programs can be limited to a predefined adjustability envelope. Adaptive algorithms and/or techniques can be used to locally adjust overall control schemes of the adaptive control programs and/or surgical instrument systems generally. Adjustments to the control program can also be based on neural networks including inputs from the surgical hub (e.g. 102, 202) and any other information that may be desirable to input into the neural networks when making adjustments to the control program.
Still referring to
In various aspects, the control program behaviors of a smart surgical device (e.g., a stapling device) could be customizable with user interaction in order to customize the performance of the device.
In one aspect, a surgical device, such as the instrument 208100, for example, could be controlled via user adjustable controls with adjustable algorithms. In at least one instance, a GUI for controlling adaptive parameters of a surgical device is disclosed. A stapler uses an adaptive firing speed algorithm that adjusts firing speed based on the resistance to firing provided by the tissue. Variables in the algorithm include the min/max speed, the number of speed intervals in the range, and the duration of the pause in firing when force parameters exceed safety thresholds. These variables are scalable or are able to be changed by the user, such as via the GUI. These inputs inform system thresholds for the subsequent firing response of the stapler.
In one aspect, local instrument controls could allow the user to adjust their function. A control can have, for example, scalable sensitivity to link an actuation control to a powered actuation movement. In one aspect, the local instrument controls can be reclassified from one function to another by the user (i.e., controls can be mapped from a first or default function to a second function).
In one aspect, trained learning (e.g., machine learning) can be utilized to assist users in customizing the performance of a device (e.g., a surgical instrument, such as the instrument 208100, for example, or hub (e.g. 102, 202)). For example, a user could input their personal opinion of the output the device has provided in its most recent uses. The device could then use this additional information to better adjust the performance of controlled functions of the device. Further, the user could then have the ability to input an opinion on the relative performance of the second use of the device to the first use of the device. This trained behavior would allow the device to personally tune not only its behavior, but the desired outcomes. For example, one of the more skilled people in the practice could input their opinions on the performance/functions of the device to tune the performance/functions and then allow the device to present this improved output behavior to all the other users of the device.
In at least one instance, there can be provided a control interface, such as a graphical user interface or any suitable control interface, to allow a clinician to choose if they want to override the learned or set limitations to a nominal value. In other words, the user may be prompted and asked if they would like to reset the adaptive control program before using the end effector, such as end effector 208111, for example. Such a reset may set the device to a manufacturer's suggested default state. In at least one instance, the current state of the adaptive control program is shown to a user as well as its learned or set limits. A user may then be able to choose whether or not they would like to utilize this customized performance. In at least one instance, a brief history of the current state of the adaptive control program can be shown to the user. For example, what surgeons have used and contributed to the adaptive control program and its limits and/or what operating room staff's were involved during the data aggregation to arrive at the current state of the adaptive control program may be shown to the next user to allow the next user to decide if the adaptive control program is in a desirable state for use in their procedure. Such an override can be selected before, after, and/or during use of the end effector 208111. More specifically, such an override can be selected during actuation of an end effector function itself. In such an instance, a surgeon may have second thoughts about the state of the adaptive control program during firing based on real-time events and/or behavior of the end effector and would like to override the adaptive control program and/or limits set on the adaptive control program.
In at least one instance, a user may be provided the ability to completely disable the ability for limits to be set on the adaptive control program. Further to this, the user may be provided the ability to completely disable the adaptiveness of the adaptive control program such that controlling the function of the end effector may be entirely manually operated in a sense that machine learning will not affect the way that the end effector function is actuated and/or controlled, for example.
In at least one instance, a control circuit, such as the control circuit 208103, for example, can be configured to identify a user of the end effector, such as end effector 208111, for example, based on the behavior of the user using the end effector. In such an instance, an adaptive control program can adapt as described above and limits can be learned and/or set on the adaptive control program as described above. If the control circuit determines that a different user is using the end effector 208111, the new user may be made aware of the adaptive control program set in place on the current end effector and can be asked if the new user would like to continue with the current adaptive control program. In at least one instance, if the control circuit determines that a different user is using the end effector, the adaptive control program may exclude the use of the end effector under the new user from affecting the adaptive control program and/or the limits of the adaptive control program of the end effector.
An example of the benefit of user detection will now be described. For example, thicker tissue than expected and an uneven distribution of the tissue where the tissue skews to a tissue stop end of an anvil may be detected. This could be adjusted for by slowing down the firing speed of the firing member in the beginning of the firing stroke and increasing the stabilization wait period. Waiting for tissue to regulate and flatten out within the jaws can aid in advancing a firing member through thicker tissue. If a similar event occurs but the control circuit detects that a different user is using the instrument, such as the instrument 208100, for example, during the same scenario, the control circuit could ask if the user if they want to use the improved performance program, or adaptive control program with its learned and/or set limitations, or if the user wants to use the standard adaptive control program rather than merely adjusting the parameters automatically as it would for the first user using the device in a subsequent procedure. This can provide an advantage in a scenario where different users have different preferences when performing similar procedures.
In at least one instance, a user may be able to define and/or select a range and/or window of values to which an adaptive control program may be able to adapt within. Referring to
In at least one instance, a user could be able to input their opinion of the output of the device and thus the performance of the adaptive control program and its learned limits, for example. Such a survey could take place after an entire procedure is complete and/or after a week's use of a device. In another instance, such a survey could take place after the lifetime use of the device such that machine learning can use this surveyed data in the control programs of the next device to better adjust the performance of the control functions. Such opinions could correspond to the device's performance from one use to the next use and/or from one procedure to the next procedure, for example. This trained behavior would allow the device to personally tune not only its behavior but the desired outcomes. This could be done by one of the more skilled people in the practice and then allow the device to present this improved output and behavior to all of the other users of the device.

Unless specifically stated otherwise as apparent from the foregoing disclosure, it is appreciated that, throughout the foregoing disclosure, discussions using terms such as “processing,” “computing,” “calculating,” “determining,” “displaying,” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.
One or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that “configured to” can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.
The terms “proximal” and “distal” are used herein with reference to a clinician manipulating the handle portion of the surgical instrument. The term “proximal” refers to the portion closest to the clinician and the term “distal” refers to the portion located away from the clinician. It will be further appreciated that, for convenience and clarity, spatial terms such as “vertical”, “horizontal”, “up”, and “down” may be used herein with respect to the drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and/or absolute.
Those skilled in the art will recognize that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”
With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flow diagrams are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
It is worthy to note that any reference to “one aspect,” “an aspect,” “an exemplification,” “one exemplification,” and the like means that a particular feature, structure, or characteristic described in connection with the aspect is included in at least one aspect. Thus, appearances of the phrases “in one aspect,” “in an aspect,” “in an exemplification,” and “in one exemplification” in various places throughout the specification are not necessarily all referring to the same aspect. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more aspects.
Any patent application, patent, non-patent publication, or other disclosure material referred to in this specification and/or listed in any Application Data Sheet is incorporated by reference herein, to the extent that the incorporated materials is not inconsistent herewith. As such, and to the extent necessary, the disclosure as explicitly set forth herein supersedes any conflicting material incorporated herein by reference. Any material, or portion thereof, that is said to be incorporated by reference herein, but which conflicts with existing definitions, statements, or other disclosure material set forth herein will only be incorporated to the extent that no conflict arises between that incorporated material and the existing disclosure material.
In summary, numerous benefits have been described which result from employing the concepts described herein. The foregoing description of the one or more forms has been presented for purposes of illustration and description. It is not intended to be exhaustive or limiting to the precise form disclosed. Modifications or variations are possible in light of the above teachings.
