摘要： An end effector assembly (114) includes a first jaw member (114a) having a first tissue contact surface (122) and a second jaw member (114b) having a second tissue contact surface (122). The second jaw member (114b) is pivotally coupled to the first jaw member (114a). The tissue contact surfaces (122) may include raised steps (122b) that define an exhaust channel (124). A longitudinally extending knife slot (214) may be defined in one or both of the tissue contact surfaces (122). One or more exhaust slots (216), which may be defined in one or both of the tissue contact surfaces (122), are in communication with the knife slot (214). The exhaust channel (124) and the exhaust slots (216) direct fluid away from the jaw members (114a, 114b) to minimize thermal damage risks associated with tissue sealing.

摘要： A cooling assembly for use with an electrosurgical instrument is provided. The cooling assembly includes a body, and a cavity. At least a portion of an inner perimeter of the body is configured for selective engagement with a jaw member of the electrosurgical instrument. The cavity is defined within the body and configured to contain a fluid therein. The fluid is capable of at least one of cooling or thermal insulation to areas laterally adjacent the jaw member.

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.
