    Abstract: A forceps includes first and second shaft members and a trigger assembly. The first and second shaft members each have a jaw member disposed at a distal end thereof. One or both of the jaw members are moveable to position the jaw members between an open position and a closed position. One of the jaw members is configured for reciprocation of a blade therethrough. The trigger assembly is movable between unactuated and actuated positions to selectively translate the blade between a retracted position and one or more extended positions. The blade extends at least partially through one or both of the jaw members in the one or more extended positions such that when the blade is disposed in the one or more extended positions, the trigger assembly is configured to move to the unactuated position upon movement of the jaw members from the closed position to the open position.

    Abstract: A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members one of which is movable with respect to the other. A heat activated drive assembly operably couples to an actuation mechanism that is operably associated with the forceps and configured to supply thermal energy to the heat activated drive assembly. The heat activated drive assembly operably coupled to movable jaw member and configured to impart movement of the movable jaw member when the actuation mechanism is activated.

    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.
