Abstract
A jaw member for use with an electrosurgical forceps includes a support member having a first surface and a pair of depending sides which extend therefrom forming a generally U-shaped configuration. The free end of the sides each including a flange which extends outwardly therefrom which is designed to attach to an electrically conductive plate such that the plate bridge the two flanges to enclose the U-shaped support member to form a box-like skeleton having a cavity defined therein. An insulative material is disposed within the cavity and an insulative cover is disposed about a periphery of the box-like support skeleton to insulate surrounding tissue during activation of the conductive plate.

A method for manufacturing a jaw member comprising the steps of:
- providing a conductive plate and a support member;
- attaching the conductive plate to the support member to form a box-like support skeleton having a cavity defined therein;
- inserting a filler material into the cavity to support the conductive plate against the support member;
- and
- forming an insulative cover on an outer periphery of the box-like support skeleton.
A method for manufacturing a jaw member comprising the steps of:
- providing a conductive plate and a U-shaped support member having flanges that extend therefrom;
- attaching the conductive plate to the flanges along a length thereof to form a box-like support skeleton having a cavity defined therein;
- injecting an insulative filler material into the cavity to insulate and support the conductive plate against the U-shaped support member;
- and
- attaching an insulative cover to an outer periphery of the box-like support skeleton.
