Abstract:
A surgical end effector assembly includes a pair of jaw members, a knife defining a longitudinal slot, a pivot pin coupling the jaw members to one another, and a drive member including a drive pin that is engaged to the jaw members. The pivot pin and/or the drive pin extends through the longitudinal slot of the knife to couple the knife to the jaw members and/or the drive member. The end effector assembly is transitionable between a use position, wherein the knife and drive member are generally aligned with one another to facilitate releasable engagement of the end effector assembly with a surgical instrument, and a cleaning position, wherein the jaw members, knife, and drive member are fanned apart from one another to facilitate cleaning of the end effector assembly. Methods of disengaging and sterilizing end effector assemblies for reuse are also provided.
