This disclosure relates generally to the field of minimally invasive surgery (MIS), and more specifically to the field of control systems and interfaces for MIS. Described herein are control interfaces for medical devices.
Surgical procedures can be performed with either an open method, where a large incision is made to access the surgical site, or a minimally invasive surgery (MIS) method, where multiple smaller incisions are made, and slender instruments are used to manipulate tissue at the surgical site. MIS, also known as keyhole or laparoscopic surgery, offers numerous advantages to the patient, such as decreased blood loss, reduced scarring, and reduced length of hospital stay. However, in many cases, the MIS approach is exceedingly difficult to perform, and the open method is implemented instead. A number of causes contribute to the challenges of MIS, but the main difficulties stem from the limitations of the control systems (e.g., interface) for surgical instruments. While many control systems have been developed to address some of the difficulties, conventional control systems still suffer from drawbacks. For example, drawbacks include: having control interfaces that allow instrument articulation with minimal consideration of control interface ergonomics and enabling too many degrees of freedom with a single control interface, resulting in the control of instrument articulation being counterintuitive or even confusing.
Accordingly, there exists a need to develop new control mechanisms that allow improved control for both orientation and position of surgical instruments while maintaining a comfortable and ergonomic control interface to a surgeon.
In some aspects, the techniques described herein relate to a control system for a medical device, the control system including: a first interface configured to control a position of the medical device, the first interface including a handle grip coupled to a base member, the base member being coupled to a device attachment unit configured to couple to the medical device; a second interface installed in a first portion of the handle grip and configured to control an end-effector orientation of an end-effector of the medical device, the second interface being communicatively coupled to a sensor assembly to monitor movement detected at the second interface; and a third interface installed in a second portion of the handle grip and configured to control a function of the end-effector, the third interface being communicatively coupled to the sensor assembly to monitor movement detected at the third interface.
In some aspects, the techniques described herein relate to a method of performing a surgical procedure, the method including: actuating, at a first interface of a control system, an input control to position a medical device relative to a remote center of motion; actuating, at a second interface, a first portion of a handle grip configured to control an orientation of an end-effector of the medical device, the second interface being communicatively coupled to a sensor assembly to monitor movement detected at the second interface; and actuating, at a third interface, a second portion of the handle grip configured to control a function of the end-effector, the third interface being communicatively coupled to the sensor assembly to monitor movement detected at the third interface.
In some aspects, the techniques described herein relate to a control system for a medical device, the control system including: a first interface configured to control a position of the medical device, the first interface including a handle grip coupled to a base member, the base member being coupled to a device attachment unit configured to couple to the medical device; a second interface installed in a first portion of the handle grip and configured to control an orientation of an end-effector of the medical device; and a third interface installed in a second portion of the handle grip and configured to control a function of the end-effector.
In some aspects, the techniques described herein relate to a control system for a medical device, the control system including: a first interface configured to control a position of the medical device, the first interface including a handle grip coupled to a base member, the base member being coupled to a device attachment unit configured to couple to the medical device; and a second interface installed in the handle grip and configured to control an orientation of an end-effector of the medical device and a function of the end-effector.
In some aspects, the techniques described herein relate to a control system for a medical device, the control system including: a first interface configured to control a position of the medical device, the first interface including a handle grip coupled to a base member; a second interface installed in a first portion of the handle grip and configured to control an orientation of an end-effector of the medical device, the second interface being communicatively coupled to a sensor assembly to monitor movement detected at the second interface; and a third interface installed in a second portion of the handle grip and configured to control a function of the end-effector, the third interface being communicatively coupled to the sensor assembly to monitor movement detected at the third interface.

Some of the challenges of MIS stem from the limitations of the control systems (e.g., interface) for surgical instruments. For example, the control systems for surgical instruments often lack the ability to provide movement dexterity for the surgeon, making it difficult to perform fine tasks, such as suturing, in highly confined spaces. While many control systems have been developed to fit at least some of these criteria, they still suffer from drawbacks, such as balancing instrument articulation with control interface ergonomics. Further, control systems often enable multiple or most degrees of freedom at a single control interface, which makes instrument articulation, via the control interface, counterintuitive or confusing. Accordingly, there exists a need to develop new control mechanisms that at least (1) allow improved control for both orientation and position of medical devices (e.g., surgical instruments), (2) decouple instrument orientation from instrument position for finer, more intuitive instrument control, and (3) maintain a comfortable and ergonomic interface for the user (e.g., a surgeon) using such control systems.
Minimally invasive surgery, in many cases, include processes that can be or should be performed independently, for example, gross positioning of a medical instrument (e.g., a first interface control), robotic assisted actuation of a medical instrument (e.g., a second interface control), and/or actuation of an end-effector of a medical instrument (e.g., a third interface control). The devices and methods described herein are ergonomically and intuitively formulated to reduce or minimize unintended movements of the medical instrument or unintended actuations of the medical instrument. Unintended movements and actuations of medical instruments may result in unintended consequences, which may cause serious ramifications in surgical procedures. As such, ergonomic and intuitive controls may help lower the chances of unintended movements or actuations by increasing usability of controls. Further, ergonomic, intuitive, spatially separated, and/or selective isolation of interface controls may reduce human errors that are a result of a mismatch between expectations of the user and the functions of the interface controls. Still further, increased usability of controls may include the ease of manipulating one interface (e.g., a first, a second, or third) independently of one or more other interfaces. Embodiments described herein may separate, decouple, or lock control interfaces (e.g., first, second, third, etc.) functionally (e.g., manual versus robotically assisted), and/or spatially. For example, the second interface may be spaced apart from the third interface such that interaction with the second interface does not impact or effect movement in the third interface. Similarly, the third user interface may be spaced apart from the second interface such that interaction with the third interface does not impact or effect movement in the second interface. Further, in some embodiments, at least a portion of a stabilizing apparatus may lock (i.e., be selectively isolated or locked) when a second and/or third interface is in use, such that at least a portion of the first interface is not manipulatable or movable when the second and/or third interface is in use. As such, a user of a control system may be less likely to interact with an unintended control interface. Ergonomic and intuitive controls for surgical robotic systems have been contemplated and described herein.
Decoupling position from orientation control may increase or improve familiarity and/or adoption of any of the control systems described herein. For example, users coming from conventional minimally invasive surgery systems may be expecting movements similar to manual instruments that do not engage extra degrees of freedom. As the user becomes comfortable or familiar with the control system, additional degrees of freedom can be engaged and used by the user, for example by interacting with additional interfaces of the control system described herein. For example, when a user is interacting with a first interface, the control interface feels like a manual handle; when the user interacts with the second and/or third interface, the handle actuates robotic-assisted movements which may be intuitive or similar to the interactions with the second and/or third interface controls.
Spatial separation may include positioning interface controls on separate portions of a control system. For example, some of the embodiments described herein position a third interface on a lower portion of an inner grip portion of a handle and a second interface in an upper portion of an inner grip portion of the handle (see, e.g.,
Selective isolation and/or locking may include inactivating one or more interfaces while another interface is in use. Alternatively, selective isolation and/or locking can include locking one or more interfaces in an actuated position or unactuated position while another interface is in use.
One factor that can contribute to some of these challenges is the design of the control interface for a medical device (e.g., a surgical instrument) that includes an end-effector, such as a gripper, that is intended to have multiple degrees of freedom. Because conventional minimally invasive surgical instrument control systems couple orientation and positional controls together, it is often difficult to provide controls that are intuitive to a user operating such controls because several degrees of freedom are coupled together. That is, the orientation may inadvertently change when a position is changed because the control system may provide controls that couple the orientation with the position. The systems and methods described herein define a control system with interfaces that allow for reduced cognitive load on a user and an ability to control both orientation and position in a decoupled, but simultaneous fashion.
A unique technical problem arises in conventional minimally invasive surgical instruments (e.g., medical devices) with greater than five degrees of freedom. The technical problem is how to control all available degrees of freedom simultaneously and intuitively. This technical problem is compounded when the medical device (e.g., instrument) is physically connected to a control system. That is, the fulcrum effect occurs during MIS when the instrument is inserted into the surgical site, thereby creating a fulcrum point at the incision. The fulcrum effect results in a distal end of an instrument moving in an opposite direction than the control system or interface (operated by the surgeon) due to the fulcrum point created at the incision. Without appropriate or new control interfaces, the fulcrum effect can render conventional instruments non-intuitive and difficult to use with respect to the motor skills utilized for properly controlling the instruments. The control systems described herein may provide control interfaces for a minimally invasive medical device that provide a technical solution to these technical problems. Further, although the control systems described herein may be described with respect to operation of a system in a fulcrum-effect mode, one of skill in the art will appreciate that the systems described herein may also be used in a system operating in a fulcrum-effect corrected mode (i.e., movement of a proximal control interface is mirrored at a distal end of the instrument).
For example, the control systems described herein may provide intuitive interfaces (e.g., user interface controls) with ergonomic benefits, such as reducing demand on wrists, arms, and/or finger movements performed by the user. In particular, the control systems and associated interfaces described herein may be provided in a handle and/or an associated handle grip (e.g., a handle assembly) to allow a surgeon to control a medical device similar to how the surgeon would control a manual instrument. Some advantages of the described control systems may include the ability to manipulate a dexterous wrist, having relatively improved ergonomics and reduced fatigue as compared to purely manual manipulation of an instrument (e.g., without stabilizing support structures), while also providing a similar level of fine motion control as compared to fully-robotic systems.
While conventional control apparatuses have coupled orientation and position control together, the control systems described herein decouple the position control from the orientation control. The decoupling occurs not only at the apparatus mechanism level but also through user biomechanical actuation of the control system and associated medical device. In particular, the control systems described herein provide for position to be sufficiently controlled by forearm and wrist motions, while orientation is sufficiently controlled by finger motions. The biomechanical actuation of the control systems described herein provides (e.g., for a surgeon) a natural control language that combines inherent surgical training and familiarity with manual surgical tools within minimally invasive surgery.
Further, the control systems described herein provide for a natural extension of existing manual surgical tool interactions translated into a laparoscopic procedure because the control systems allow the use of one or more fingers to control movement of medical devices about the pitch, yaw, and roll axes. The control systems described herein provide an improved solution to the field of minimally invasive surgery (e.g., laparoscopic surgery) by enabling a surgeon to use such a natural control language associated with manual surgical techniques with robotics surgical techniques. In particular, a surgeon may use the control systems and associated user interfaces (mechanical and electromechanical) by using one or more fingers to trigger movements and/or functions of a medical device and/or end-effector.
As used herein, an “end-effector” may include a grasper, a forceps, a scissors, a suturing device, a cutting tool, an ablation element, a cryo-element, a cutting element, a suturing element, a drilling element, milling element, a camera, a needle driver, electro-cautery tool, and the like, such that actuation of the end-effector results in ablation, cryo-activity, cutting, suturing, drilling, milling, electro-cautery, etc.
The term “communicatively coupled” may be defined as either wireless communication (i.e., wirelessly coupled) between components or a wired connection between components.
In some implementations, the control system is a handle assembly configured for installation in a hybrid, direct-control and robotic-assisted surgical system, as illustrated in
In some embodiments of the control systems described herein, the functionality controlled by the third interface may be combined with the second interface such that there is no third interface. In such embodiments, the second interface controls a distal end of the medical device (e.g., wrist joint and/or end-effector) about the roll, pitch, and/or yaw axes while also controlling a functionality of the distal tip (e.g., grasping, energy delivery, etc.).
In some implementations, the interfaces described herein may be beneficial for hybrid surgical robotic control where the control system is physically connected to the instrument (e.g., medical device) because such interfaces may provide an intuitive movement similar to a conventional laparoscopic handle with the added benefit of mechanical and electromechanical controls that decouple the position from the orientation of the medical device. In general, the systems described herein provide a new control system for a medical device (e.g., a surgical instrument) that allows for scaling and processing of user input into proportional control of an orientation of a robotic end-effector attached to the medical device. Processing of the user input into proportional control allows for motion scaling, limiting, and filtering.
In alternative configurations, the interfaces of various control systems described herein may be purely mechanical (e.g., via cable systems). In other embodiments, any combination of mechanical and electromechanical implementations for any of the interfaces may be employed.
The control systems described herein include a number of user interfaces to provide a plurality of degrees of freedom (DOFs) of movement, for example at least three, four, five, or more degrees of freedom, of the medical device (or a portion of the medical device).
For example, a control system may enable gross mechanical positioning of a medical instrument relative to a base of a stabilizing apparatus, using the various joints of the stabilizing apparatus. Gross mechanical movements of the medical instrument, received at a first interface of a handle (e.g., a grip portion of the handle) and using the stabilizing apparatus, result in a first DOF including movement about a yaw axis of the stabilizing apparatus; and a second DOF including movement about a pitch axis of the stabilizing apparatus. For a third DOF, the medical instrument may be inserted and retracted via a device attachment unit (e.g., via a prismatic joint) and relative to the stabilizing apparatus. For a fourth DOF, the control systems described herein may be rolled about a roll axis to effect a roll movement of the medical instrument. A rolling movement of the control system about a roll axis is with respect to a first attachment point, as discussed in further detail below.
Further, the control systems described herein can include a second interface. The second interface may be in the form of a barrel, joystick control, ring, or the like of a handle having an installed medical device. The second interface may be capable of electro-mechanical movement to provide movement of the end-effector about at least three degrees of freedom. For example, manipulation of the second interface may cause an end-effector of a medical device to: roll about an end-effector roll axis for a first DOF, move about an end-effector yaw axis for a second DOF, and move about an end-effector pitch axis for a third DOF, relative to a resting or unactuated state of the second interface. In some implementations, rolling the second interface results in a proportional rolling of the end-effector about the end-effector roll axis. Although movement about an end-effector roll axis, an end-effector yaw axis, and an end-effector pitch axis are used, one of skill in the art will appreciate that the second interface may be manipulated in any number of intermediate positions between each of the end-effector axes of movement to effect fine wrist joint or medical device tip movements. By manipulating the second interface, a user may be able to control an orientation of an end-effector of the medical device in the at least three degrees of freedom. In addition to robotic surgical systems, surgical devices and systems with manual manipulation of a single instrument with multiple functions or multiple instrument types may benefit from control systems described herein.
In some implementations, the control systems described herein allow for a fourth DOF by enabling control of an end-effector function. This fourth DOF may be enabled by additional functionality at the second interface or by a third user interface.
In some implementations, the control systems described herein allow for movement that provides a wrist movement by actuating the first interface about a roll axis, which has a center of axis offset from the shaft of the medical device. For example, the user may grasp a handle and sweep the handle counterclockwise or clockwise about a pivot point attaching the handle to a control system base. Such a movement rolls the medical device clockwise or counterclockwise about the instrument roll axis.
The control systems described herein include a second interface in the form of a manipulatable control that allows adjustment of an end-effector about an end-effector pitch axis and an end-effector yaw axis. For example, a user can engage the interface and manipulated it about the end-effector pitch axis and the end-effector yaw axis relative to a resting (unactuated) position of the second interface. Such user movements may trigger end-effector movements in corresponding directions and rotationally at angles between such directions. The second interface may allow a roll movement of the end-effector (about a wrist joint of the end-effector) when a user engages the second interface in a twist or spin motion. For example, a twist or spin of the second interface may trigger the end-effector (or a wrist joint of the end-effector or a tip of the medical device) installed in the handle (or associated control system) to roll (e.g., spin on the roll axis of the medical device) in a clockwise or counterclockwise direction according to a particular movement direction selected and performed by the user.
The control systems described herein can include a third interface. The third interface may be in the form of a compressible control. The compressible control may provide an electromechanical actuation of one or more functions of an end-effector of the medical device. For example, the end-effector may have a plurality of predefined functions and such functions may be triggered by a user interacting with the compressible control. Example functions include, but are not limited to, closing of mechanical jaws, administration of electrical energy, administration of cryotherapy, cutting motions, grasping motions, a material removal function (e.g., cutting, drilling, deburring, etc.), an irrigation function, a suction function, a stapling or adhesive function, etc.
In some implementations, the third interface may take the form of one or more buttons, a touchpad, a ring, a lever, a compressive portion of a barrel or joystick (described above), or an actuator including one or more sensors that allow for continuous actuation and latching of the third interface at a maximum actuation point. This latching may provide for maximum actuation of the medical device (e.g., the end-effector function(s)) without continuous interaction from the user. For example, the function may provide for sustained grasping of human tissue without continued interaction with the third interface.
As illustrated, the robotic surgical system 100 includes a remote base 104 that provides stabilization for a support arm 105 and pivotable arm 106. The remote base 104 is attached to a patient support apparatus 102 at a first attachment point 108 and attached to a first end of the support arm 105. Although the attachment point is illustrated attached to a surface of the patient support apparatus 102, other implementations may clamp to attachment points that are rails, slats, raised platforms, a ceiling system or rail, and the like. The attachment of the remote base 104 to the patient support apparatus 102 may be achieved in a number of ways, such as a clamping mechanism, a bolting system, or the like. The patient support apparatus may be either manufactured with connection points or a connection method specifically for the attachment of the base 104, or the base 104 may be designed such that it can be attached to any existing operating table or patient support apparatus.
A second end of the support arm 105 is attached to a first end of the pivotable arm 106 at a second attachment point 109. A second end of the pivotable arm 106 is attached to a first end of a stabilizing apparatus 110 (e.g., including a parallelogram movement mechanism) at an attachment point 112. In some implementations, attachment point 112 includes a revolute joint, which enables movement of the medical instrument about a yaw axis 123 of stabilizing apparatus 110. The stabilizing apparatus 110 enables a second DOF of the medical instrument about a pitch axis 119 of the stabilizing apparatus.
The robotic surgical system 100 also includes a control system 114. The control system 114 is attached to the stabilizing apparatus at a second end of the stabilizing apparatus 110. The control system 114 includes user interfaces (described in detail below), electronics (described in detail below), and a device attachment unit 116 that is removably attached to a medical instrument 118. The support arm 105, base 104, and/or stabilizing apparatus 110 may function to support (or partially support) the weight of the control system 114 and/or any installed medical device(s). For example, the stabilizing apparatus 110 may define a remote-center-of-motion (i.e., at pivot point or insertion point 125). The remote base 104 is configured to be fixed relative to a patient. The stabilizing apparatus 110 is attached to the device attachment unit 116. The device attachment unit 116 is movable relative to the stabilizing apparatus 110, and ultimately the remote base (e.g., base 104), and is configured to removably receive the control system 114. In some implementations, the remote base 104 may define a first positional reference frame 122 while a portion of the control system 114 may define a second positional reference frame 120.
In operation, the control system 114 and one or more interfaces of the handle 103 allow for pitch, yaw, and roll control of the distal wrist joint of the end-effector 124. Such a configuration provides for orientation control of the end-effector 124 of the medical instrument 118. The control system 114 provides a number of interfaces used to orient the end-effector 124 about end-effector pitch, roll, and/or yaw axes. The movements received at the one or more interfaces may result in proportional movements of the end-effector 124.
The attached medical devices described herein (e.g., medical instrument 118) have a wristed end-effector 124 at their tips with at least three degrees of freedom, such as pitch, yaw, and roll capabilities. The attached medical devices described herein may also include grasping and/or other or additional end-effector actuation to provide a surgeon with an increased degree of manipulation of the end-effector 124 and/or medical instrument 118 at the surgical site as compared to a non-wristed medical device. As it can be difficult to control multiple degrees-of-freedom of an end-effector mechanically, the device attachment unit 116 includes a controller and a powered actuation unit that is configured to control the orientation of the end-effector 124 of the medical instrument 118.
For example, the device attachment unit 116 may include electronics (not shown) therein. In some implementations, the device attachment unit 116 may provide motorized units that may be operatively coupled to the medical instrument 118. The device attachment unit 116 is configured to receive an elongate body 204 of the medical instrument 118. The device attachment unit 116 is also configured to receive mechanical and electronic commands via control system 114. In some implementations, the powered actuation unit may reside in the device attachment unit 116. In some implementations, the powered actuation unit may reside in a housing or control housing or box for the device attachment unit 116.
The control system 114 may include at least a controller communicatively coupled to a sensor assembly to receive corresponding sensor signals and to generate a corresponding primary control signal. In addition, the control system 114 may include the powered actuation unit communicatively coupled to the controller to receive each primary control signal. The powered actuation unit is configured to actuate the end-effector 124 of the medical instrument 118, based on each received primary control signal when the medical instrument 118 is received (e.g., installed) in the device attachment unit 116.
As illustrated in
In some implementations, the handle grip 304 is movable relative to the device attachment unit 116 about at least a first degree of freedom, for example to roll the medical instrument 118 about a roll axis 117. The handle grip 304 may also function as a first interface, which may be used by the user to determine and set an orientation of the handle grip 304 about the first degree of freedom.
As illustrated, the handle grip 304 is configured with a first interface that provides for mechanically (but could also be electromechanically implemented) based movement of the control system 100, using the various joints of the stabilizing apparatus 110 (illustrated in FIG. 1). The first interface is configured to control a position of the medical device. In some implementations, the first interface can be used to position the medical instrument 118 (and/or a distal tip of end-effector 124) into a particular position using a user-selected positional reference frame. For example, the user may move the system 100 in space to position the medical instrument 118 by maneuvering the first interface (e.g., the handle 302) using one or both of a forearm and a wrist (not shown) to cause movement of the medical device. In this example, the first interface comprises the handle 302 configured to receive a grip of a user. The user may then provide movement of system 100 using the handle 302 (and/or handle grip 304).
For example, a user may move the system 100 about one or both of the pitch axis 119 (illustrated in
Therefore, as illustrated in
Illustrated in
The second interface may provide control inputs for electromechanical movement for system 100. For example, the second interface may be communicatively coupled to a number of electronics, sensors, and/or motors that allow a user to use the second interface (e.g., via the joystick 314) to change the orientation of the end-effector 124, as illustrated in detail in
In some implementations, the second interface includes a tiltable and/or rotatable joystick finger interface. A user may actuate the second interface by manipulating the joystick 314 of the handle grip 304 with one or more fingers, for example a thumb and a finger in some implementations. Movements performed at the second interface (e.g., joystick 314) may cause a change in orientation of the end-effector 124 or distal tip about a first axis 403 (e.g., end-effector pitch axis), a second axis 401 (e.g., end-effector yaw axis), and/or a third axis 405 (end-effector roll axis). For example, the second interface (e.g., joystick 314) includes an electromechanical controller subsystem configured to receive and translate inputs (produced by the second interface) to articulate the end-effector 124 about the first axis 403 (e.g., a pitch axis), the second axis 401 (e.g., a yaw axis), and the third axis 405 (e.g., a roll axis). Although the second interface (e.g., joystick 314) is illustrated as being positioned along an inner surface or inner grip portion of handle 302, one of skill in the art will be appreciate that the second interface (e.g., joystick 314) may be positioned along an outer grip or palm portion of handle 302, along a lower portion 317 of handle 302, for example in place of third interface (e.g., compressible control 316), or otherwise for ergonomic movement of the second interface (e.g., joystick 314).
In some implementations, the second interface includes a ringed finger interface portion (e.g., ring portion 566 of
In some implementations, the second interface is communicatively coupled to a sensor assembly to monitor movement detected at the second interface (e.g., the joystick, ring, etc.). For example, the second interface (e.g., the joystick 314, ring portion, etc.) may be connected to one or more electrical cables and a wireless or wired communication protocol. In some implementations, the sensor assembly may be configured to monitor a position of a handle, second interface (e.g., joystick 314), a trackball, a triggering of a switch or button, a pressure applied to a pressure sensitive sensor, and the like using suitable sensors. The sensor assembly may be configured to use the monitoring to trigger generation of a corresponding sensor signal.
A sensor signal, associated with one or more of the interfaces described herein, can be provided to a suitable controller (that may be a computer, PLC, microprocessor, and the like) that can receive the sensor signal and generate a corresponding control signal that is appropriate for the medical instrument 118 and/or end-effector 124 (illustrated in
As illustrated in
In some implementations, the third interface (e.g., compressible control 316) may be communicatively coupled to the sensor assembly (similar to the second interface) to measure movement at the third interface (e.g., compressible control 316). The sensor assemblies described herein may include at least one potentiometer (e.g., rotary or linear) or encoder (e.g., linear or rotary) to detect an orientation of the component or interface housing the sensors of the particular assembly. For example, the sensor assemblies described herein may include one or more potentiometers or encoders to detect the orientation of the second interface (e.g., the handle 302 about at least one of the pitch, roll, and yaw axes; and/or a state (e.g., activated vs. deactivated, compressed vs. decompressed, etc.) of the third interface (e.g., compressible control 316). Alternatively, the third interface may be purely mechanical (not electromechanically controlled).
In operation, a user may operate the handle 302 to engage with the tiltable and rotatable second interface (e.g., joystick 314) and/or the third interface (e.g., compressible control 316). To actuate the second interface and cause movement of the end-effector 124, the user may move the second interface (e.g., joystick 314) by gripping the second interface with one or more fingers, for example a thumb and a finger. Movements performed at the second interface (e.g., joystick 314) may cause a change in orientation of the end-effector 124 about a first axis 403 (e.g., pitch axis), a second axis 401 (e.g., yaw axis), and/or a third axis 405 (roll axis), as illustrated in zoomed-in view 402. Actuating the third interface (e.g., compressible control 316) and causing movement and triggering one or more functions of the end-effector 124, may include the user gripping the third interface. In some implementations, the third interface (e.g., compressible control 316) includes one or more additional controls such as trackpad, buttons, switches, and the like. For example, the third interface (e.g., compressible control 316) may function to lock a wrist in a selected orientation, to lock an end-effector in a selected configuration, to lock the handle in a selected orientation, to zero an orientation of the wrist, etc.
The handle 302 (and/or handle grip) is configured as a mechanical interface for receiving input from a forearm, wrist, and/or hand of a user (i.e., a first interface). For example, the user may use a forearm or hand to engage with handle 302 to provide input (e.g., grasp, twist, push, pull, lift, lower, and/or rotationally move) to position an installed medical device relative to a predefined positional reference frame, as illustrated by axis 502 or relative to a remote center of motion (shown as pivot point or insertion point 125, illustrated in
The second interface (e.g., joystick, barrel, etc.) is configured as an electromechanical interface for receiving finger input. For example, the user may use one or more fingers to engage with second interface (e.g., the joystick 314 described for
By way of a non-limiting example, a user or a robotic interface may actuate the first interface (e.g., the joystick 314 as described for
In some implementations, the plurality of inputs provided at the second interface include motions received at the second interface (e.g., joystick 314). The motions may be performed by fingers of the user to engage electromechanical components (e.g., sensorized joints) to orient the end-effector 124. In some implementations, the motions may be performed by a robotic interface to engage electromechanical components to orient the end-effector 124.
In some implementations, the trigger input includes one or more finger inputs received at the finger interface of the third interface (e.g., the compressible control 316 described for
In some implementations, the control housing 508 includes components for detecting sensor signals from one or more of the sensor assemblies described herein. The sensor signals may be translated and provided to components of the control housing 508 in order to change the position and/or orientation of the end-effector about at least one of the pitch, roll and yaw axes.
In some variations, the second interface (e.g., a joystick 314
Although the second interface (e.g., the joystick 314 as described for
The third interface (e.g., compressible control 316) is configured as a compressible finger interface configured to receive and translate a trigger input to control the function of the end-effector of the medical device and/or to maintain a state of the end-effector, as described in detail above. In some implementations, the compressible control input is provided in another location of control system 114 to enable a thumb or other finger to engage the third interface. For example, the third interface (e.g., compressible control 950) of the control system embodiment of
In some implementations and as illustrated by
The handle 552 (and/or handle grip) is configured as a mechanical interface for receiving input from a forearm, wrist, and/or hand of a user. For example, the user may use a forearm or hand to engage with handle 552 to provide input (e.g., grasp, twist, push, pull, lift, lower, and/or rotationally move) to position an installed medical device relative to a predefined positional reference frame, as illustrated by axis 502. The axis 502 may move with the control system 550 as the user moves the handle. The handle 552 is illustrated attached to a base 558 at a pivot point 560. Such positional movements, received at a first interface (e.g., handle 552), are described in greater detail in connection with
The joystick 554 is configured as an electromechanical interface for receiving finger input. For example, the user may use one or more fingers to engage with joystick 554 to provide input (e.g., adjust orientation of an end-effector about a pitch, yaw, and/or roll axis) to select an orientation for an end-effector of the medical device (see also
By way of a non-limiting example, a user or a robotic interface may actuate the first interface (e.g., handle 552) by providing a first input. The first input may be a manual input. For example, the manual input may be an input performed by a user as a mechanically actuated input with the handle 552. In some implementations, the manual input may be an input performed by a robotic interface that provides a mechanically actuated input at the handle 552. The input may be a mechanical input providing movement of the control system (or a component thereof) that is coupled to the medical instrument 118 without engaging electromechanical components of the control system.
In some implementations, the plurality of inputs provided at the second interface include motions received at the joystick 554. The motions may be performed by fingers of the user to engage electromechanical components to orient the end-effector 124, for example. In some implementations, the motions may be performed by a robotic interface to engage electromechanical components to orient the end-effector 124. Such motions will be described in greater detail in connection with
In some implementations, the third interface (e.g., compressible control 556 or trigger input) includes one or more finger inputs received at the finger interface. The one or more finger inputs may be configured to engage additional electromechanical components to perform a predefined function of the end-effector 124. In some implementations, the one or more finger inputs may be performed by a robotic interface to engage additional electromechanical components to perform a predefined function of the end-effector 124. The one or more finger inputs may engage with a barrel portion 564 of the joystick 554 and/or a ring portion 566. For example, the user may use a thumb and a forefinger to engage with ring portion 566 to turn the joystick 554 to trigger an end-effector 124 to move or otherwise perform a function. In some implementations, the user may use at least one finger to engage the ring portion 566 to move the joystick 554 (e.g., about an end-effector pitch, yaw and/or roll axis). Actuation of the ring portion 566, in some embodiments, may be decoupled from actuation of the barrel portion 564. For example, manipulation of the ring portion 566 may not affect actuation of the barrel portion 564 or manipulation of the barrel portion may not affect actuation of the ring portion 566. As such, a user may manipulate the ring portion 566 independently of the barrel portion 564 and vice versa. In one exemplary, non-limiting embodiment, the ring portion 566 is manipulated using one finger and the barrel portion 564 is manipulated using a second, different finger. The barrel portion 564, depicted as being ergonomically positioned for thumb and/or finger actuation, may include a potentiometer (or encoder), which measures a roll orientation about the roll axis 565. The measured roll orientation may be received by the control system to roll the end-effector in the same direction. For example, if the barrel portion 564 is rolled to the left, the end-effector 124 would be rolled to the left about the roll axis 405 (illustrated in
In some implementations, the control housing 562 includes components for detecting sensor signals from one or more of the sensor assemblies described herein. The sensor input may be translated and provided to components of the control housing in order to change the position and/or orientation of the end-effector about at least one of the pitch, roll, and yaw axes.
The joystick 554 also includes a joystick switch 568 that provides electromechanical interaction between one or more sensors (not shown) associated with the joystick 554 and other components of the control system 550. In particular, the switch 568 may allow the joystick 554 to pivot within the handle grip. In some implementations, the switch 568 is also communicatively coupled and electrically coupled to components in the control housing 562 to enable transfer of signals between the input mechanisms of control system 550 and the outputs affecting articulation of the end-effector and/or movement of the medical device.
Although the joystick 554 in the handle grip associated with handle 552 is depicted substantially perpendicular to the y-axis, the joystick 554 may be installed within the handle grip at any angle. For example, the joystick 554 may be installed in the handle grip from about zero to about fifteen degrees in the x-y axis. In some implementations, the joystick 554 may be installed at about −5 degrees to about −15 degrees in the x-y axis. In some implementations of the control system 550, the joystick 554 may be installed in other locations within the handle grip.
The third interface (e.g., compressible control 556) is configured as a compressible finger interface configured to receive and translate a trigger input to control the function of the end-effector of the medical device and/or to maintain a state of the end-effector, as described in detail above. In some implementations, the trigger input is provided in another location of control system 550 to enable a thumb or other finger to engage the third interface (e.g., compressible control 556). For example, the third interface (e.g., compressible control 950) of the control system embodiment of
In operation, a user may grasp the handle 302 and may move the handle about a pivot centerline or instrument roll axis 604. In particular, a handle portion 606 may pivot about a base portion 608 in the direction of arrow 610 and arrow 612 in a sweeping motion. The sweeping motion may be from about −180 degrees to about 180 degrees (or any subrange therebetween) of movement about the instrument roll axis 604. The sweeping motion provides a natural wrist turning motion for the user. That is, the instrument roll axis 604 of the system is configured to be substantially aligned with an anatomically natural arm movement of the user. In other embodiments, the instrument roll axis 604 of the system is configured to be offset relative to an anatomically natural arm movement of the user. In some embodiments, the rotatable interface at the handle portion 606 and base portion 608 may be sensorized, for example, with a potentiometer or encoder. As such, the rotational position of the handle portion 606 about the instrument roll axis 604 and with respect to the base portion 608 may be measured and transmitted to the control system 114 to translate the input and carry out movements to control the rotational orientation of the end-effector 124 about the roll axis 405 (illustrated in
In operation, the user may orient the end-effector 124 about pitch axis 403, yaw axis 401, and/or roll axis 405 (illustrated in
In operation, the user may operate the third interface (e.g., compressible control 316) by placing a hand around handle 302 and placing a first, a second and/or a third finger on any of the grip locations 904, 906, 908 or intermediate positions therebetween. Once one or more fingers are placed on the third interface (e.g., compressible control 316), the user may squeeze the third interface to trigger at least one function of an end-effector (e.g., end-effector 124 illustrated in
In some implementations, the grip locations 904, 906, 908 may each be associated with a different function for the end-effector. Selecting each different function may cause the end-effector to perform a different function. In some implementations, the user may use the joystick (e.g., the second interface of handle 302) in combination with the third interface (e.g., compressible control 316) to move the medical device in up to four degrees of freedom of movement relative to the base member pivotally connected to the handle 302 via pivot point 902.
The user may use any grip on handle 1008 to move the medical device 1004 in space to position the device 1004 by maneuvering the first interface (e.g., the handle 1008) using one or both of a forearm and a wrist to cause movement of the medical device along and about both the pitch and yaw axes, using the coupled stabilizing apparatus 1010 (e.g., using a parallelogram movement mechanism) and a remote base 1012 (sometimes also configured as a revolute joint) as a counterbalancing mechanism. In addition, the user may maneuver the handle 1008 using one or both of a forearm and a wrist to cause movement of the medical device 1004 about a roll axis 1007. In this example, the forearm or wrist align with an offset of the roll axis 1007 of the medical device 1004 (illustrated in
The user may roll the handle 1008 clockwise and counterclockwise about a centerline axis 1112. The centerline axis 1112 is parallel to the instrument roll axis associated with the medical device 1004. The movement of the handle 1008 may be a sweeping motion from about 165 degrees to about 180 degrees of movement about the roll axis. The sweeping motion provides a natural wrist turning motion for the user. That is, the roll axis of system handle 1008 about centerline axis 1112 is configured to be aligned with an anatomically natural arm movement of the user.
In some implementations, the user may engage with the joystick control 1202 using the thumb 1108 and at least one finger (e.g., finger 1110) to twist or spin the joystick control 1202 about the roll axis (illustrated in
The second interface control may include a roll barrel 20. In some embodiments, the roll barrel 20 includes two portions: a first portion 14a and a second portion 14b. In some embodiments, the roll barrel 20 portions 14a and 14b may be coupled together. Alternatively, in some embodiments, roll barrel 20 may include one portion, two portions, or one or more portions. The roll barrel 20 may be operatively coupled to the control system via a barrel coupling 26. The barrel coupling 26 may include a rolling mechanism (e.g., a roller bearing, etc.) and a position measuring sensor (e.g., a potentiometer, an encoder, etc.) for measuring a roll orientation of the roll barrel 20 about a roll axis 24. The roll barrel 20 may be rotated about a roll axis 24 via a finger and/or a thumb in contact with the first portion 14a and/or the second portion 14b. The rotation of the roll barrel 20 may be measured by the position measuring sensor of the barrel coupling 26 and may be received by the control system. The measured roll orientation may be received by the control system to roll the end-effector in the same direction. For example, if the roll barrel 20 is rolled to the left, the end-effector 124 would be rolled to the left about the roll axis 405 (e.g., see also

Mode selection in some embodiments may be accomplished with a mechanical mode selector as illustrated in
Trigger-locking, as described herein, is mechanically performed, but roboticized trigger-locking has been contemplated, for example, autonomous braking for retaining the position of control element (e.g., trigger 16, trigger 216, compressible control 316, etc.). Robotic surgical systems (or any instance where an instrument may have multiple functions or multiple instrument types may be used with the same handle) may benefit from trigger-locking, especially those in which trigger position corresponds to grasp pressure, for example, end-effectors such as needle drivers (at least in some instances) may benefit from locking the grasp pressure onto a needle during suturing and easily unlocking to relieve grasp pressure. Another example of a system that may benefit from trigger-locking may be plain graspers. Plain graspers may be used to engage a material (e.g., tissue during tissue retraction) and it may be beneficial to lock the engagement pressure of the graspers. Further, some robotic surgical systems may benefit from a trigger-unlocked mode, for example, a system utilizing scissors or shears may increase performance with trigger-unlocked mode. In addition, robotic surgical systems in which end-effector actuation has increased performance with rapid activation and rapid deactivation may benefit from trigger-unlocked mode. For example, a bipolar electrocautery end-effector may benefit from trigger-unlocked mode and the capability of intermittent controlled energy application.
The control system 2000 illustrated in
Although robotic surgical system embodiments described herein are in the singular form, it is contemplated that two or more robotic surgical systems may be mounted to the patient support apparatus 102 (illustrated in
The method 1500 may be carried out using a robotic surgical system 100 that includes a number of robotic-assisted components as well as manually movable components. Such a system may include at least a handle 103, 302 (with a handle grip 304) coupled to a control system 114 that may be manipulated by a forearm and/or wrist, and/or one or more fingers of a user (e.g., a surgeon). For example, any of the systems, components, interfaces, or handle assemblies of
At block 1502, the method 1500 includes actuating, at a first interface of a control system, an input control to position a medical device relative to a selected positional reference frame. For example, an input received at the first interface (e.g., the handle 302) may cause movement of the medical instrument 118 to be positioned in space relative to a positional reference frame associated with the handle 302 or relative to a remote center of motion of the system. In some implementations, the positional reference frame may be defined by a horizontal or vertical centerline associated with the handle 302, the medical instrument 118, and the like. In some implementations, the positional reference frame may be defined by a portion of the control system 114 that is coupled to the handle 302. In some implementations, the positional reference frame may be defined by a remote component that is affixed to an arm when the arm is also affixed to the control system 114 and/or handle 302. In some implementations, the positional reference frame may be defined relative to a remote center of motion, for example at an incision or surgical access site of the patient.
In some implementations, actuating the input control (e.g., the handle 302 at the first interface) includes maneuvering the first interface (e.g., the handle) using one or both of a forearm and a wrist to cause movement of the medical instrument 118 about an instrument roll axis associated with the selected positional reference frame. For example, the actuation may be a twisting motion of the handle 302 about a pivot point where the twisting or pivoting motion includes the user grasping the handle 302 and twisting the handle clockwise or counterclockwise about the centerline of the roll axis associated with the handle (e.g., axis 307. In this example, the forearm or wrist of a user may be offset from the roll axis associated with the medical instrument 118.
At block 1504, the method 1500 includes actuating, at a second interface, a first portion of a handle grip configured to control an orientation of an end-effector of the medical device. For example, an input received at the second interface (e.g., any of the second interfaces of
In some implementations, actuating the first portion at the second interface includes a user gripping the first portion (e.g., the second interface 314) of the handle grip 304 with a thumb and a finger. That is, to actuate the second interface, a user may move the second interface 314 (e.g., a joystick) by gripping the joystick of the handle grip 304 with a thumb and a finger. Movements performed at the second interface 314 (e.g., a joystick) may cause a change in orientation of the end-effector 124 about an end-effector pitch axis, an end-effector yaw axis, and/or an end-effector roll axis (illustrated
At block 1506, the method 1500 includes actuating, at a third interface, a second portion of the handle grip configured to control a function of the end-effector. For example, an input received at the third interface (e.g., the compressible control 316) may trigger a function of the end-effector 124 of the medical instrument 118, as described herein. In some implementations, actuating the second portion at the third interface comprises gripping the second portion (e.g., lower portion) of the handle grip 304 with one or more fingers of the user. Any of the third interfaces of any of the control systems of
In some implementations, the third interface (e.g., the control 316) may be coupled to the sensor assembly to monitor input detected at the third interface and to provide detected input to one or more controllers, electronics, and the like, to carry out end-effector functions according to the detected input. In some implementations, actuation of each of the input control, the first portion, and the second portion is mapped to a separate hand portion or body portion, as described in herein. Such mapping may improve ergonomics of the user and/or allow medical instrument positional control independent of end-effector orientation control.

The systems described herein may be useable with many different types of medical instruments. As such, the methods of use are to remain substantially the same as to further the intuitive nature of using different types of medical instruments with robotic surgical systems described herein. For example, regardless of what type of medical instrument is loaded into the system, the first interface of the system may be used for gross positioning of the medical instrument, the second interface of the system may be used for robotically assisted movement of the medical instrument, and the third interface of the system may be used for the actuation of the end-effector of the medical instrument. For example, in some embodiments, a method of using any of the control systems described herein includes: loading a first type of medical instrument into a device attachment unit; manipulating the first type of medical instrument with a control system attached to the device attachment unit (e.g., including a first interface, a second interface, and/or a third interface); decoupling or unloading the first type of medical instrument from the device attachment unit; loading a second type of medical instrument into the device attachment unit; and manipulating the second type of medical instrument with the control system.
