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.
