摘要： A surgical system includes an attaching device having an end effector disposed at the distal end thereof. The end effector includes a support member, a wrist pivot pivotably coupling the end effector to the attaching device, and first and second jaw members pivotably coupled to one another and the support member. A first cable is operably coupled to the wrist pivot and configured to articulate the end effector relative to the attaching device. Second and third cables are operably coupled to the jaw members and configured to pivot the jaw members relative to the support member. A first actuation of the second and third cables collectively pivots the first and second jaw members relative to the support member. A second actuation of the second and third cables pivots the first and second jaw members relative to one another and the support member between a spaced-apart position and an approximated position.

摘要： An electrosurgical instrument includes an elongated shaft extending distally from a housing and an actuating mechanism operably coupled to a proximal portion of the elongated shaft and configured to move the elongated shaft. First and second jaw members are coupled to a distal portion of the elongated shaft. The first jaw member is pivotable relative to the second jaw member between open and closed positions. An electrically conductive tissue sealing surface is disposed on each of the jaw members and is adapted to connect to a source of electrosurgical energy. A tissue-dissecting electrode is disposed on a distal end of at least one of the jaw members in spaced relation to the tissue sealing surface and is adapted to connect to a source of electrosurgical energy. An insulator couples the tissue-dissecting electrode to the jaw member and electrically insulates the tissue-dissecting electrode from the jaw member.

摘要： An end effector assembly for a surgical instrument includes a pair of jaw members each including one or more tissue-contacting plates. One or both jaw members is movable relative to the other between spaced-apart and approximated positions for grasping tissue between the tissue-contacting plates. The tissue-contacting plates are adapted to connect to a source of energy for conducting energy through tissue grasped between. One of the jaw members includes an insulative member extending towards the other member. The insulative member includes a plurality of crests each defining a blunt apex and a proximally-facing sharpened edge. The blunt apexes contact tissue upon approximation of the first and second jaw members to grasp tissue, while the proximally-facing sharpened edges facilitate tissue cutting in a ripping fashion upon proximal translation of the end effector assembly relative to tissue.

摘要： A surgical instrument includes a housing having an elongated shaft that extends therefrom and a handle pivotable relative thereto. An end effector assembly is attached to a distal end of the shaft and includes first and second jaw members. The first jaw member is pivotably attached to a distal end of the shaft and the second jaw member extends along a longitudinal axis defined therethrough and fixed to the distal end of the shaft by a living hinge. The first jaw member, upon actuation of the handle, is movable relative to the second jaw member between spaced-apart position, an approximated position for grasping tissue, and a second position for over-compressing tissue grasped between jaw members. A knife is disposed within a channel defined within the second jaw member and is exposed to cut tissue when the first jaw member over-travels to over-compress the second jaw member.

摘要： A surgical instrument includes an end effector assembly having first and second jaw members each jaw member defining an opposed surface. The jaw members are movable between a spaced-apart position and an approximated position for grasping tissue within a grasping area. First and second tissue-treating plates are disposed on the jaw members and adapted to connect to a source of energy for treating tissue disposed within a tissue-treating. Each jaw member defines a knife channel positioned within the grasping area and outside of the tissue-treating area. A knife is selectively movable between a retracted position, wherein the knife is positioned proximally of the jaw members, and an extended position, wherein the knife extends at least partially through the knife channels of the jaw members to cut tissue positioned adjacent the tissue-treating area.
