Patent ID: 8439911

Claim:
An end effector assembly for use with a forceps, the end effector assembly comprising: a clevis supporting a pair of jaw members and a pivot, the clevis having a proximal end face and defining a clevis bore with a non-circular cross-section that extends longitudinally through the clevis from the proximal end face of the clevis, the clevis bore configured to receive an actuator that moves at least one jaw member of the pair of jaw members relative to the other about the pivot from a first, open position to a second, closed position for grasping tissue, at least one of the jaw members including a knife channel defined therein that extends therealong, the pivot defining a pivot bore therethrough; a knife assembly including a knife blade and an actuation shaft, the knife blade disposed distally relative to the pivot, the actuation shaft configured for slidable translation through the pivot bore to allow selective advancement of the knife blade through the knife channel; and at least one cam assembly operably coupled to the at least one jaw member and actuatable by the actuator to move the at least one jaw member from the first position to the second position for grasping tissue between the pair of jaw members.
