Compact jaw including split pivot pin

摘要

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 between open and closed positions. One or more of the jaw members include a knife channel. The pivot includes first and second sections defining a passage therebetween. 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 passage 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 between the open and closed positions for grasping tissue therebetween.

1. An end effector assembly comprising:
a pair of jaw members, at least one of the pair of jaw members moveable about a pivot between an open position and a closed position relative to the other jaw member for grasping tissue, the pivot including first and second sections and defining a passage between the first and second sections; a knife blade supported between the pair of jaw members distal to the pivot and coupled to an actuation shaft, the actuation shaft slidably translatable through the passage of the pivot to advance the knife blade; a cam pin coupled to at least one of the pair of jaw members to move the at least one jaw member upon selective longitudinal translation of the cam pin through a cam slot defined in at least one of the pair of jaw members; and a knife tube mounted to the pivot, the cam pin slidably engaged with the knife tube, the first and second sections of the pivot being engageable with a recess defined by the knife tube.
