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 end effector assembly suitable for use with a forceps includes opposing first and second jaw members pivotably mounted with respect to one another. The first jaw member includes one or more pivot holes defined therein configured to receive a portion of a pivot pin therein. The end effector assembly also includes an electrically-insulative hinge configured to electrically isolate the first and second jaw members from one another including one or more pivot-hole locators having an aperture defined therein. The electrically-insulative hinge is attached to the first jaw member such that the one or more pivot-hole locators align with the one or more pivot holes of the second jaw member.

Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position.

Abstract: An electrosurgical forceps includes a handle having a shaft extending therefrom defining a longitudinal axis. The handle is selectively movable to translate movement of the shaft along the longitudinal axis to actuate a pair of laterally spaced first and second jaw members pivotably connected to a distal end of the shaft. The first and second jaw members are moveable from an open position, wherein the first and second jaw members are in spaced relation relative to a stationary jaw member, to a closed position wherein the first and second jaw members cooperate with the stationary jaw member to grasp tissue therebetween. Each of the jaw members is adapted to connect to an electrosurgical energy source to conduct energy through tissue grasped therebetween to effect a tissue seal.

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, illuminating optical light into the grasped tissue at the first jaw member, receiving the optical light that has passed through the grasped tissue, at the second jaw member, processing the received light to identify a vessel, which is encompassed within the grasped tissue, 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.
