Apparatus for performing an electrosurgical procedure

Abstract

A surgical instrument is provided and includes a housing having a shaft. An end effector assembly operatively connects to the shaft and has a pair of first and second jaw members. A jaw insert is operably associated with the first and second jaw members. The jaw insert includes one or more cam slots defined therein configured to receive a cam pin that upon movement thereof rotates the first and second jaw members from an open position to a clamping position and an opening defined therein configured to securely house a pivot pin that provides a point of pivot for the first and second jaw members. The jaw insert is manufactured from an insulative medium to dielectrically isolate the first and second jaw members.

What is claimed is: 
     
         1 . A forceps, comprising:
 a housing having at least one shaft that extends therefrom that defines a longitudinal axis therethrough;   an end effector assembly operatively connected to a distal end of the at least one shaft and having a pair of first and second jaw members, the first and second jaw members movable relative to one another from an open position wherein the first and second jaw members are disposed in spaced relation relative to one another, to a clamping position wherein the first and second jaw members cooperate to grasp tissue therebetween; and   a jaw insert operably disposed within at least one of the first and second jaw members, the jaw insert including at least one cam slot defined therein configured to receive a cam pin that upon movement thereof rotates the jaw members from the open position to the clamping position and an opening defined therein configured to securely house a pivot pin that provides a point of pivot for the first and second jaw members,   wherein a spring operably couples to the jaw insert, the spring configured to provide a camming force to the cam slot and a portion of a sealing force to the jaw members when the first and second jaw members are in a clamping position.
