Abstract
An end effector assembly for use with a forceps includes a pair of jaw members, a knife assembly, and one or more cam assemblies. One or more of the jaw members are moveable relative to the other about a pivot from a first, open position to a second, closed position. One or more of the jaw members include a knife channel. The pivot includes a bore. The knife assembly includes a knife blade and an actuation shaft. The knife blade is disposed distally relative to the pivot. The actuation shaft is configured for slidable translation through the bore to allow selective advancement of the knife blade through the knife channel. The one or more cam assemblies are operably coupled to the one or more moveable jaw members and are actuatable to move the one or more jaw members from the first to second position for grasping tissue therebetween.
