Patent ID: 8480671

Claim:
An end effector assembly for use with a forceps, the end effector assembly comprising: a pair of jaw members, at least one jaw member moveable relative to the other about a pivot between an open position and a closed position for grasping tissue, at least one of the jaw members including a knife channel defined therein that extends therealong, the pivot having first and second sections defining a passage therebetween; a knife assembly including a knife blade and an actuation shaft, the knife blade disposed distally relative to the pivot and the actuation shaft configured for slidable translation through the passage defined between the first and second sections of the pivot to allow selective advancement of the knife blade through the knife channel; at least one cam assembly operably coupled to the at least one moveable jaw member and actuatable to move the at least one jaw member between the open and the closed position for grasping tissue therebetween, wherein the at least one cam assembly includes an actuator configured to move the at least one movable jaw member between the open and the closed position upon selective longitudinal translation thereof, wherein the actuator includes at least one cam pin extending therefrom and wherein at least one jaw member defines at least one cam slot therein such that the at least one cam slot and the at least one cam pin are configured to cooperate with one another to move the at least one moveable jaw member; and a knife tube mounted to the pivot wherein the at least one cam pin is configured to slidably engage the knife tube upon the selective longitudinal translation of the actuator, wherein the knife tube defines a recess adapted to mount each of the first and second sections of the pivot at the distal ends thereof, the distal ends of each of the first and second sections defining a profile configured to engage the recess.
