An ultrasonic surgical instrument includes an inner tube, an outer tube, an ultrasonic blade, and a clamp member pivotably moveable relative to the ultrasonic blade. The ultrasonic blade is acoustically coupled to an ultrasonic transducer. The clamp member pivotably movable relative to the ultrasonic blade between an open configuration and an approximated configuration with respect to the ultrasonic blade, wherein the clamp member is pivotably coupled to the inner tube, wherein the clamp member is pivotably coupled to the outer tube, and wherein movement of the outer tube relative to the inner tube between the first position and the second position transitions the clamp member between the open configuration and the approximate configuration.

Actuation mechanisms and load adjustment assemblies for surgical instruments

A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The trigger includes a compliant feature configured to limit the amount of force delivered to tissue by the clamp arm. The flexible feature may comprise a flexible band, living hinge, a series of living hinges, or a flexible tab.

Handpiece and blade configurations for ultrasonic surgical instrument

Various embodiments of surgical robot control systems are disclosed. In one example embodiment, the surgical robot control system comprises a housing. A controller is located within the housing and is coupled to a socket. The socket receives a handheld surgical user interface therein to control a surgical instrument. The surgical instrument is connected to the surgical robot and comprises an end effector and a mechanical interface to manipulate the end effector. The mechanical interface is coupled to the controller. At least one sensor is coupled to the controller and the socket to convert movement of the handheld surgical user interface into electrical signals corresponding to the movement of the surgical instrument. At least one feedback device is coupled to the controller to provide feedback to a user. The feedback is associated with a predetermined function of the surgical instrument.

Haptic feedback devices for surgical robot

An apparatus includes an anvil, a closure assembly, a firing assembly, and a casing assembly. The firing assembly includes a staple driver and an annular array of staples. The casing assembly includes a first section and a second section. The first section includes a first handle portion, a first shaft portion, and a tubular casing. The tubular casing slidably houses the staple driver. The first section defines a homogenous continuum of material along the length of the first handle portion, the first shaft portion, and the tubular casing. The second section includes a second handle portion and a second shaft portion. The second handle portion is laterally coupled with the first handle portion. The second shaft portion is laterally coupled with the first shaft portion. The second section defines a homogenous continuum of material along the length of the second handle portion and the second shaft portion.

Circular stapling instrument with asymmetric molded shroud components

A surgical tool and control system therefor is provided. The surgical tool can include an instrument mount configured to engage with a robotic manipulator assembly, which can include a gear assembly configured to be actuated by the robotic manipulator assembly. The surgical tool can include an end effector coupled to the gear assembly, which is configured to be actuated by the gear assembly. The surgical tool can include a lockout configured to transition between a first state in which the lockout is physically engaged with the gear assembly to prevent a movement thereof and a second state in which the lockout is disengaged from the gear assembly. The surgical tool can include a control circuit configured to determine whether the end effector is in an energized state or a de-energized state and in the energized state, cause the lockout to transition between the first state and the second state.

Lockout mechanism for use with robotic electrosurgical device

A surgical control system is disclosed including a controller, a feedback device operably coupled to the controller, and a user interface operably coupled to the controller. The user interface is configured to provide an input to the controller. The controller is configured to provide a control signal to a robotic surgical system to control a function of the robotic surgical system, receive a feedback signal from the robotic surgical system, and provide the feedback signal to the feedback device. The feedback device is configured to provide feedback associated with the robotic surgical system to a user in response to the feedback signal.

A surgical tool including a lockout mechanism is provided. The surgical tool may include an instrument mounting portion including a shaft assembly coupled to and extending distally from the instrument mounting portion and an end effector including a reciprocatable element coupled to a distal end of the shaft assembly. The surgical tool may further include an energy source configured to deliver energy to the end effector and an actuation mechanism configured to actuate the end effector. The actuation mechanism may be configured to reciprocate the reciprocatable element of the end effector. The lockout mechanism may be operably interfaced with the actuation mechanism to control reciprocating movement of the reciprocatable element.

A control system for a surgical robot is disclosed. The control system includes a controller, a sensor, a feedback device, a first socket, and a stand-alone input device. The handheld user interface may control a function of a robotic surgical system and is coupled to the sensor and the controller. The sensor is coupled to the controller. The feedback device is coupled to the controller and is configured to provide feedback associated with the robotic surgical system to a user. The controller is communicatively coupleable to the robotic surgical system and is configured to send robot control signals to the robotic surgical system, to receive feedback signals from the robotic surgical system, and to send feedback control signals to the feedback device to control the feedback provided to the user. The controller is configured to couple to a stand-alone input device through the first socket.

Feedback devices for surgical control systems

Surgical stapler

Various embodiments described herein are directed to surgical instruments with visual feedback. In one embodiment, a surgical instrument with visual feedback comprises an end effector. The end effector has a first jaw member and a second jaw member. At least one sensor is coupled to the end effector. The at least one sensor is configured convert at least one state of the end effector to a feedback signal. The feedback signal is corresponding to the at least one state of the end effector. The feedback signal may be transmitted to a display to render a visual representation of the at least one state of the end effector. The surgical instrument may further comprise an instrument mounting portion to mount to a robotic surgical system. The instrument mounting portion comprises an interface to mechanically and electrically interface to the surgical instrument.

Surgeon feedback sensing and display methods

A medical device includes an end effector configured to apply bipolar energy to target tissue along a working portion thereof and a fluid control system to control the flow of a fluid produced when the end effector applies the bipolar energy to heat the target tissue. The fluid control system includes a fluid path element defining a fluid path, a distal fluid port configured to intake the fluid adjacent to the working portion of an end effector for transport through the fluid path, and a proximal fluid port configured to intake the fluid transported through the fluid path and to exhaust the transported fluid.
