The present disclosure relates generally to systems, devices, and methods for use in performing surgical procedures, and more specifically, relates to surgical robotic systems, devices, and methods for use in performing surgical actions including, but not limited to, minimally invasive surgical procedures (MIS) and natural orifice transluminal endoscopic surgical procedures (NOTES).
Conventionally, surgical procedures performed in a body cavity of a patient, such as the abdominal cavity, required one or more large access incisions to a patient in order for the surgical team to perform a surgical action. With advancements in medical science and technology, such conventional surgical procedures have been largely replaced by minimally invasive surgery (MIS) procedures and, where applicable, natural orifice transluminal endoscopic surgical procedures (NOTES). Recent developments in respect to computer-assisted and/or robotic surgical technology have contributed to advancements in the MIS and NOTES fields, including the ability to translate a surgeon's desired surgical actions into precise movements of surgical instruments inside a body cavity of a patient.
Despite recent developments in modern medical science and technology, it is recognized in the present disclosure that one or more problems are encountered in modern surgical technology and methodology. For example, a typical MIS procedure requires multiple incisions to a patient in order to allow access via the incisions for the insertion of a camera and various other laparoscopic instruments into the body cavity of the patient.
As another example, surgical robotic devices oftentimes encounter difficulties during surgical procedures due to insufficient anchoring and/or reactive forces to stabilize against forces that are desired and/or necessary to be applied during surgical actions.
It is also recognized in the present disclosure that surgical robotic systems face difficulties in providing an instrument, such as a cutting or gripping instrument attached to the end of a surgical robotic arm, with access to all or even most parts, areas, and/or quadrants of abdominal cavity of a patient. That is, after the surgical robotic arm is inserted in the abdominal cavity of the patient and ready to perform a surgical action, the instrument attached to the end of the surgical robotic arm is typically limited to access only certain parts, areas, and quadrants of the abdominal cavity of the patient.
In yet another example, known surgical robotic systems typically provide only between one to two surgical robotic arms per access or opening (such as an incision or a natural orifice) of the patient. In this regard, one or more additional incisions will be required for the insertion of a camera and various laparoscopic instruments into the abdominal cavity of the patient.
Present example embodiments relate generally to systems, devices, and methods for addressing one or more problems in surgical robotic systems, devices, and methods, including those described above and herein.

Although similar reference numbers may be used to refer to similar elements in the figures for convenience, it can be appreciated that each of the various example embodiments may be considered to be distinct variations.

Despite recent developments in medical science and technology, problems continue to exist in modern surgical technology and methodology, including those pertaining to MIS and NOTES.
For example, a typical MIS procedure will generally require a surgeon to perform multiple incisions to a patient in order to enable the surgeon to insert, via such incisions, required laparoscopic instruments into the body cavity of the patient. Furthermore, it is recognized herein that a significant technical challenge encountered when using surgical robotic systems pertains to the difficulty in establishing sufficient anchoring and/or reactive forces to react to and/or stabilize against forces that need to be applied inside the body cavity of the patient by the surgical robotic system during a surgical action. In this regard, the use of known systems to perform certain surgical actions may require tremendous effort and time, and eventually may not be performed properly or at all due to such insufficient anchoring and/or reactive forces. Furthermore, surgeons using known surgical systems often encounter problems in respect to utilizing an instrument, such as a cutting and/or gripping instrument attached to the end of a surgical robotic arm, in certain parts, areas, and quadrants of a body cavity (such as an abdomen) of a patient after the system has been set up (or anchored) and ready to perform surgery. That is, after the surgical robotic arm of the system has been inserted and properly set up in the abdominal cavity of a patient, the surgical instrument attached to the end of the surgical robotic arm is typically mechanically limited to accessing only certain parts, areas, and quadrants of the abdominal cavity of the patient.
As another example, known surgical robotic systems typically only provide for between one to two surgical robotic arms per access or opening (such as an incision or a natural orifice) of the patient. In this regard, when additional laparoscopic instruments, such as another surgical robotic arm, a suction tube, and/or a camera, are required to be inserted into the abdominal cavity of the patient, one or more additional openings (incisions) are required to be performed on the patient. For such incisions, surgical teams also often encounter difficulties with properly inserting and removing surgical robotic systems, such as surgical robotic arms, into and out of the body cavity. Specifically, since surgical robotic arms generally have at least one joint and two arm segments, the insertion (and removal) of a surgical robotic arm into the body cavity oftentimes results in a portion of the surgical robotic arm (such as the end connected to an instrument, such as a cutting tool) coming into contact with and damaging patient tissue. This problem becomes compounded when a surgical procedure or system attempts to employ more than one surgical robotic arm through a single port.
Known surgical robotic systems also oftentimes face problems in respect to the heating up of one or more components during a surgical action, such as the heating up of laparoscopic optics (such as a camera), lighting elements, and other components. It is recognized in the present disclosure that increased temperature of such components may impose in-surgery and/or post-surgery damage or complications to patient tissues that come into contact with such components. Laparoscopic optics (such as a lens of a camera) and/or lighting elements in known surgical systems also tend to encounter contamination and/or partial or complete blockage during a surgical procedure due to fogging, tissue debris, liquids (such as blood), and/or other particles accumulated before, during, and/or after insertion of such components into the body cavity. In this regard, visibility within a body cavity via such laparoscopic optics and lighting elements may become reduced, deteriorated, or even completely blocked as a result.
Recent technological developments have introduced solutions to the aforementioned problems. U.S. patent application Ser. No. 14/693,207 to Yeung et al. (“U.S. '207”), herein incorporated by reference in its entirety, describes surgical robotic devices, systems, and methods for solving the above-mentioned problems. For example, U.S. '207 teaches a surgical system having a port assembly for use in providing sufficient anchoring and reactive forces to counter forces applied by a surgical arm of the surgical system during a surgical action. The surgical system of U.S. '207 enables a surgeon to not only perform a single small incision to the patient but also enable the surgeon to utilize one or a plurality of laparoscopic instruments, including surgical robotic arms, suction tubes, and/or camera arms, in an abdominal cavity of the patient through such single small incision (via the port assembly). U.S. '207 further teaches a surgical arm configurable to provide for 7 in vivo degrees of freedom, thereby enabling a surgical instrument attached to the surgical arm to access all parts, areas, and quadrants of a body cavity. The combined design of the port assembly, surgical robotic arms, and attachment portions for attaching the surgical robotic arms to the port assembly further enable easy and controllable insertion and removal of surgical robotic arms so as to prevent unintended contact with and damaging patient tissue.
In addition to the above-mentioned problems of known surgical systems encountered during forward-directed surgical procedures (e.g., MIS performed in an abdominal cavity of a patient), known surgical system generally encounter additional problems when deployed through a natural orifice, such as a rectum or vagina, for performing natural orifice transluminal endoscopic surgery (or NOTES), such as trans-vaginal gynecological procedures in women and trans-rectal urological procedures in men. For example, such known systems generally encounter problems pertaining to, among other things, the inability to access certain organs, tissues, or other surgical sites upon insertion into the natural orifice due as a result of the inherent forward-directed design of such systems.
Recent technological developments have introduced solutions to the aforementioned problems. For example, U.S. patent application Ser. No. 15/044,889 to Yeung (“U.S. '889”) and U.S. patent application Ser. No. 15/044,895 to Yeung (“U.S. '895”), both herein incorporated by reference in their entireties, describe a surgical system configurable for use in performing forward-directed and/or reverse-directed surgical actions.
Surgical systems, devices, and methods, including those for use in MIS and NOTES, are described in the present disclosure. It is to be understood in the present disclosure that the principles described herein can be applied outside of the context of MIS and/or NOTES, such as performing scientific experiments and/or procedures in environments that are not readily accessible by humans, including in a vacuum, in outer space, and/or under toxic and/or dangerous conditions, without departing from the teachings of the present disclosure.
The Surgical System (e.g., surgical system 100, 200)
The surgical arm assembly (e.g., surgical arm assembly 130)
In an example embodiment, the surgical device 100, 200 may comprise one or more surgical arm assemblies, including a first surgical arm assembly (e.g., the surgical arm assembly 130, 230), second surgical arm assembly (not shown), third surgical arm assembly (not shown), fourth surgical arm assembly (not shown), etc.). Each surgical arm assembly may be configurable to secure to and unsecure from the port assembly 210.
One or more of the surgical arm assemblies (e.g., surgical arm assembly 130, 230) may comprise a configurable serial (or linear) arrangement of a plurality of surgical arm segments, including arm assembly (e.g., arm assembly 131, 231), joint portions, and at least one end-effector assembly (e.g., end-effector assembly 140, 240). For example, as illustrated in
One or more of the surgical arm assemblies (e.g., surgical arm assembly 130, 230) may also be configurable to receive an electric current (or voltage potential, thermal energy, heat, cold temperature application, etc.) from an energy source (or other source, not shown). In example embodiments, such an energy source (or other source) may also be integrated, in part or in whole, into one or more of the surgical arm assemblies (e.g., surgical arm assembly 130, 230). The electrical current (or voltage potential, thermal energy, heat, or cold temperature application) from the energy source (or other source) may be selectively applied to one or more elements of the end-effector assembly (e.g., end-effector assembly 140, 240), and such selective application of the electric current (or voltage potential, thermal energy, heat, cold temperature application, etc.) may be configured and/or controlled by the user interface (e.g., via the controller). For example, in situations wherein the end-effector assembly (e.g., end-effector assembly 140, 240) includes a first instrument (e.g., first instrument 142, 242) and a second instrument (e.g., second instrument 144, 244), an operator of the user interface (e.g., user interface 910) may configure the user interface (e.g., user interface 910) to command (e.g., via the controller) the energy source (or other source) to apply the electric current (or voltage potential, thermal energy, heat, cold temperature application, etc.) to the first instrument (e.g., first instrument 142, 242). It is recognized in the present disclosure that the application of such electric current (or voltage potential, thermal energy, heat, cold temperature application, etc.) to the first instrument (e.g., first instrument 142, 242) alone or in collective operation with second instrument (e.g., second instrument 144, 244) enables the end-effector assembly (e.g., end-effector assembly 140, 240) to perform the actions of an electrosurgical instrument, or the like.
These and other elements and example embodiments of the surgical system and surgical arm assembly (e.g., surgical arm assembly 130, 230) will now be further described with reference to the accompanying figures.

Controller
In example embodiments, the surgical system 100, 200 may include a controller (or computing device, manipulator, and/or master input device). The controller may include one or more processors. The controller may be configurable to perform one or more of a plurality of operations in, on, and/or to the surgical system 100, 200. For example, the controller may be configurable to communicate with and/or control one or more elements of the surgical system 100, 200, such as the surgical arm assembly (e.g., surgical arm assembly 130, 230), the image capturing assembly 120, 220, etc. The controller may be accessible and/or controllable by the surgical team (e.g., via a user interface), and the surgical team may be able to communicate with and/or control the configuring and/or operation of the one or more elements of the surgical system 100, 200. For example, the controller may be configurable to control a movement and action of some or all parts of the surgical arm assembly (e.g., surgical arm assembly 130, 230). The controller may be configurable to receive, from the user interface (e.g. user interface 910), user interaction information (e.g., performed by the surgical team) representative of user interactions performed on the user interface (e.g., user interface 910). The controller may be further configurable to process the received user interaction information. The controller may be further configurable to transmit, based on the processing, one or more commands to the surgical arm assembly (e.g., surgical arm assembly 130, 230). The one or more commands transmitted may include commanding the first instrument drive portion (e.g., first instrument drive portion 132, 232) to drive the first instrument driven portion (e.g., first instrument driven portion 142a, 242a) in such a way as to cause a movement of the first instrument (e.g., first instrument 142, 242) in a first direction relative to a first axis (e.g., axis A). The one or more commands transmitted may also include commanding the wrist drive portion (e.g., wrist drive portion 136, 236) to drive the wrist driven portion (e.g., wrist driven portion 146a, 246a) in such a way as to cause a movement of the first instrument (e.g., first instrument 142, 242) in a second direction relative to a second axis (e.g., axis B). The second axis (e.g., axis B) may be different from the first axis (e.g., axis A).
In an example embodiment, the controller may be configurable to detect a resistance in a movement of at least a part of the end-effector assembly (e.g., end-effector assembly 140, 240) and communicate a haptic feedback response to the user interface (e.g., user interface 910).
The controller may also be configurable to receive one or more of a plurality of responses, feedback, actions, and/or measurements from one or more elements of the surgical system 100, 200 including, but not limited to, movements of one or more elements of the surgical system 100, 200, haptic feedback responses, and responses and/or measurements pertaining to position (including orientation), applied force, proximity, temperature, pressure, humidity, etc., of, by, and/or nearby to the surgical arm assembly (e.g., surgical arm assembly 130, 230).
In an example embodiment, the controller may be configurable to receive, from the user interface (e.g., user interface 910), user interactions (e.g., by the surgical team) performed on the user interface (e.g., user interface 910) representative of commanding an energy source (not shown) to apply an electric current (e.g., a first electric current) to the first instrument (e.g., first instrument 142, 242). In doing so, such electric current (e.g., first electric current) enables the first instrument (e.g., first instrument 142, 242) to perform the actions of an electrosurgical instrument. In example embodiments, when the controller receives, from the user interface (e.g., user interface 910), the user interactions performed on the user interface (e.g., user interface 910) representative of commanding the energy source to apply (or not apply) the electric current (e.g., first electric current) to the first instrument (e.g., first instrument 142, 242) to perform (or not perform) the actions of an electrosurgical instrument, the controller may be configurable to transmit a command to the energy source to apply (or not apply) the electric current to the first instrument (e.g., first instrument 142, 242). Furthermore, the controller may be configurable to apply (or not apply) an electric current to the second instrument (e.g., second instrument 144, 244) in a similar or same manner as the first instrument (e.g., first instrument 142, 242).
In an example embodiment, when the controller detects a resistance in a movement of at least a part of the end-effector assembly (e.g., end-effector assembly 140, 240), the controller may be configurable to determine the part of the end-effector assembly (e.g., end-effector assembly 140, 240) encountering the resistance. Furthermore, the controller may be configurable to provide a haptic feedback response to the user interface (e.g., user interface 910) based on such determining.
In example embodiments, the controller may be separate from the user interface (e.g., user interface 910). Alternatively, the controller may include a part or all of the user interface (e.g., user interface 910), or may communicate with a processor of the user interface (e.g., user interface 910).
User Interface (e.g., User Interface 910)

The user interface (e.g., user interface 910) may be configurable for use by one or more operators (e.g., one or more members of the surgical team). The user interface (e.g., user interface 910) may be configurable to receive one or more of a plurality of user interactions from the one or more operators and command one or more elements of the surgical system 100, 200 to perform an action or prevent from performing an action. Such receiving may be via the controller and/or directly from the one or more elements of the surgical system 100, 200. For example, the user interface (e.g., user interface 910) may be configurable to control (e.g., via the controller) a movement of one or more parts of the surgical system 100, 200, such as the first instrument (e.g., first instrument 142, 242), second instrument (e.g., second instrument 144, 244), and other parts of the surgical arm assembly (e.g., surgical arm assembly 130, 230). The user interface (e.g., user interface 910) may also be configurable to (e.g., via the controller) enable the surgical arm assembly (e.g., surgical arm assembly 130, 230) to perform and/or disable the surgical arm assembly (e.g., surgical arm assembly 130, 230) from performing actions of an electrosurgical instrument. For example, the user interface (e.g., user interface 910) may be configurable to (e.g., via the controller) apply, control/regulate the applying of, and/or prevent the applying of an electric current (e.g., the first electric current and/or second electric current) to the first instrument (e.g., first instrument 142, 242) and/or second instrument (e.g., second instrument 144, 244).
The user interface (e.g., user interface 910) may also be configurable to receive one or more of a plurality of responses, feedback, actions, and/or measurements from one or more elements of the surgical system 100, 200 and/or the controller including, but not limited to, movements of one or more elements of the surgical system 100, 200, haptic feedback responses, and responses and/or measurements pertaining to position (including orientation), applied force, proximity, temperature, pressure, humidity, etc., of, by, and/or nearby to the surgical arm assembly (e.g., surgical arm assembly 130, 230).
In example embodiments, the user interface (e.g., user interface 910) may be separate from the controller. Alternatively, the user interface (e.g., user interface 910) may include a part or all of the controller, or may include a processor in communication with the controller.
In example embodiments, the surgical system 100, 200 may include a memory (not shown) in communication with the controller and/or user interface (e.g., user interface 910). The memory may be for use in storing information received from, processed by, and/or communicated to/from the controller and/or user interface (e.g., user interface 910).
The user interface (e.g., user interface 910) may also include one or more graphical interfaces (such as a monitor, projection system, etc.) for use in displaying video and/or audio content captured by an element of the surgical system 100, 200 (such as a camera arm assembly 120). The one or more graphical interfaces may also be for use in displaying some or all responses, feedback, actions, and/or measurements received from one or more elements of the surgical system 100, 200 and/or the controller including, but not limited to, movements of one or more elements of the surgical system 100, 200, haptic feedback responses, and responses and/or measurements pertaining to position (including orientation), applied force, proximity, temperature, pressure, humidity, etc., of, by, and/or nearby to the surgical arm assembly (e.g., surgical arm assembly 130, 230).
While various embodiments in accordance with the disclosed principles have been described above, it should be understood that they have been presented by way of example only, and are not limiting. Thus, the breadth and scope of the example embodiments described in the present disclosure should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the claims and their equivalents issuing from this disclosure. Furthermore, the above advantages and features are provided in described embodiments, but shall not limit the application of such issued claims to processes and structures accomplishing any or all of the above advantages.
For example, “assembly,” “device,” “portion,” “segment,” “member,” “body,” or other similar terms should generally be construed broadly to include one part or more than one part attached or connected together.
Various terms used herein have special meanings within the present technical field. Whether a particular term should be construed as such a “term of art” depends on the context in which that term is used. “Connected,” “connecting,” “attached,” “attaching,” “anchored,” “anchoring,” “in communication with,” “communicating with,” “associated with,” “associating with,” or other similar terms should generally be construed broadly to include situations where attachments, connections, and anchoring are direct between referenced elements or through one or more intermediaries between the referenced elements. These and other terms are to be construed in light of the context in which they are used in the present disclosure and as one of ordinary skill in the art would understand those terms in the disclosed context. The above definitions are not exclusive of other meanings that might be imparted to those terms based on the disclosed context.
As referred to in the present disclosure, a computing device, controller, manipulator, master input device, a processor, and/or a system may be a virtual machine, computer, node, instance, host, and/or device in a networked or non-networked computing environment. A networked computing environment may be a collection of devices connected by communication channels that facilitate communications between devices and allow devices to share resources. Also as referred to in the present disclosure, a computing device may be a device deployed to execute a program operating as a socket listener and may include software instances.
Resources may encompass any type of resource for running instances including hardware (such as servers, clients, mainframe computers, networks, network storage, data sources, memory, central processing unit time, scientific instruments, and other computing devices), as well as software, software licenses, available network services, and other non-hardware resources, or a combination thereof.
