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.

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 jaw assembly includes an electrically-conductive tissue-engaging structure, a jaw member including a support base, and a non-electrically conductive member including a first portion configured to engage the electrically-conductive tissue-engaging structure and a second portion configured to engage the support base of the jaw member. The non-electrically conductive member adapted to electrically isolate the electrically-conductive tissue-engaging structure from the jaw member. The electrically-conductive tissue-engaging structure and the non-electrically conductive member cooperatively define a longitudinally-oriented knife channel therethrough.

Abstract: A surgical instrument includes a housing, an energizable member, and a deployment mechanism. The deployment mechanism includes a one-way rotatable member, a linkage, and an actuator. The first end of the linkage is coupled to the one-way rotatable member at an offset position. The second end of the linkage is coupled to the energizable member such that a revolution of the one-way rotatable member moves the energizable member from the storage position to the deployed condition and back to the storage position. The actuator is selectively actuatable from an un-actuated state to an actuated state. Each actuation of the actuator effects a partial revolution of the one-way rotatable member such that each actuation of the actuator moves the energizable member from one of the storage position or the retracted position to the other of the storage position or the retracted positions.

Abstract: A forceps includes an end effector assembly having first and second jaw members moveable with respect to one another between an open position and a closed position. A knife channel having a body and a base is defined within each jaw member. A knife assembly includes a knife having a bifurcated distal end. The bifurcated end includes first and second cutting members each defining an opposed cutting surface and having a tab at a free end thereof for translation through the base of a knife channel. The knife is translatable into the channels when the jaw members are in the closed position such that the cutting members are approximated when translated through the channels. The knife is also translatable into the channels when the jaw members are in the open position such that the cutting members are flexed apart when translated through the jaw members.

Abstract: An endoscopic forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.

Abstract: A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.

Abstract: An endoscopic forceps is provided. The endoscopic forceps includes a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough. The shaft has a first tube with a bent portion having a contour. A second tube is disposed within the first tube. An end effector assembly operatively connected to a distal end of the first tube has a pair of first and second jaw members. The first and second jaw members including respective cam slots defined therein with a cam pin movable therein. The shaft is translatable along the longitudinal axis to straighten the bent portion of the first tube to move the bent portion of the first tube from an articulated configuration to a non-articulated configuration. The second tube is translatable along the longitudinal axis to move the first and second jaw members from the open configuration to the clamping configuration.

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.
