Abstract
An endoscopic forceps includes a housing having a shaft attached thereto with a longitudinal axis defined therethrough and an end effector assembly disposed at a distal end thereof. The end effector assembly includes first and second jaw members disposed in opposing relation relative to one another and moveable from a first, open position to a second, closed position for grasping tissue therebetween. Each of the jaw members includes a proximal flange adapted to communicate with a drive assembly for moving the jaw members between the first and second positions. One or both of the of the jaw members has a curved knife channel defined therein having a proximal end that is offset from the longitudinal axis defined through the shaft. A knife guide is assembled to an outer surface of one of the proximal flanges of the jaw members on the same side as the proximal end of the knife channel and defines a knife path therein configured to guide a knife into the knife channel for translation therethrough.
