Abstract: An electrosurgical instrument includes an end effector assembly including first and second jaw members. At least one of the first or second jaw members is movable about a pivot relative to the other from a spaced-apart position to an approximated position to grasp tissue between first and second opposed surfaces of the first and second jaw members, respectively. The electrosurgical instrument further includes an interface configured to provide a feedback related to a size of tissue grasped by the first and second jaw members. At least one of the first or second jaw members includes a touch sensor configured to sense a touch span where the tissue touches the at least one of the first or second opposed surfaces. The end effector assembly further includes an angle sensor configured to sense an angle α about the pivot between the first and second opposed surfaces.

Abstract: An electrosurgical system includes an end effector assembly, a display, and a controller. The end effector assembly includes first and second jaw members each defining a tissue-treating surface. At least one of the first or second jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue between the tissue-treating surfaces thereof. At least one of the first or second jaw members includes a sensor. The controller is configured to receive sensor data from the sensor, generate a tissue indication based upon the sensor data, and output the tissue indication to the display. The display is configured to display the tissue indication. The tissue indication indicates a location along the first jaw member at which tissue is grasped between the tissue-treating surfaces of the first and second jaw members.

Abstract: A method includes providing a graphical representation of a surgical site, grasping the tissue of the patient with first and second jaw members of an end effector including a location sensor, irradiating a laser onto the grasped tissue at the first jaw member, detecting laser speckle data from the grasped tissue at the first jaw member, processing the laser speckle data to identify a vessel which is encompassed within the grasped tissue by generating a laser speckle image, receiving location information of the end effector from the location sensor, synchronizing a location of the identified vessel within the graphical representation based on the location information, and displaying the identified vessel at the synchronized location in the graphical representation.

Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

Abstract: A surgical instrument includes a housing, energizable member, first activation switch, cable assembly, and second activation switch. The housing is operatively associated with the energizable member. The first activation switch is coupled to the energizable member and is selectively transitionable from an open condition to a closed condition. The cable assembly is coupled to the housing at a first end and includes a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition. The plug is adapted to connect to the source of electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the source of electrosurgical energy to initiate the supply of energy to the energizable member.

Abstract: A forceps includes first and second shaft members, each having a jaw member disposed at a distal end thereof. The first and second shaft members are pivotably coupled to one another toward the distal ends thereof and are moveable relative to one another between an open position and a closed position for moving the jaw members between a spaced-apart position and an approximated position. A knife assembly including a handle and a knife extending from the handle is also provided. The knife assembly is selectively translatable between a retracted position and an extended position, wherein the knife extends between the jaw members. The handle is disposed between the first and second shaft members and is configured to block further closure of the first and second shaft members beyond the closed position, thereby defining a minimum gap distance between the jaw members.

Abstract: A surgical instrument includes a handle assembly having an actuating rod extending therefrom, a rotating member, a release member, and a stop, the actuating rod translatable along a longitudinal axis defined therethrough. The rotating member is disposed within the handle assembly and is configured to operably engage the actuating rod via a cam and link arrangement. The release member includes a first catch configured to lock the rotating member against the force of an energy storage device in a first condition and release the rotating member to rotate in an opposite direction with the force of the energy storage device in a second condition. The stop is disposed on a peripheral edge of the rotating member and is configured to operably engage the first catch when the release member is disposed in the first condition to limit the rotational movement of the rotating member.
