Abstract

A surgical clip applier includes a housing, a channel assembly, jaw assembly, and a first insert. The channel assembly extends distally from the housing and the jaw assembly is disposed at the distal end of the channel assembly. The jaw assembly includes a first and second jaws constructed of a first material. Each of the jaws defines a recess extending longitudinally along opposing inner surfaces thereof. The first insert is disposed in the recess of at least one of the first or second jaws. The first insert is constructed of a second material different from the first material.
