Abstract

A surgical clip applier includes a handle assembly, an elongated shaft, a drive shaft, a cam pin, and an end effector. The cam pin is disposed in mechanical cooperation with the drive shaft. The end effector is disposed adjacent a distal end of the elongated shaft and includes a first jaw member and a second jaw member. The end effector is disposed in operative engagement with the drive shaft such that longitudinal translation of the drive shaft relative to the housing of the handle assembly causes the first jaw member to move toward the second jaw member. The first jaw member includes a first cam slot configured to slidingly receive the cam pin. The first cam slot defines a first portion having a first slope and a second portion having second slope.
