Method for manufacturing an end effector assembly
First Claim
1. A method for manufacturing a jaw member of an end effector assembly for use with an electrosurgical instrument, the method comprising the steps of:
- providing an electrically conductive tissue engaging plate, said electrically conductive tissue engaging plate having vertically-extending edges extending about a periphery and along a length thereof of said electrically conductive plate, and a jaw support;
covering one side of the electrically conductive tissue engaging plate and said vertically-extending edges with an electrically insulative, thermally non-degrading coating;
placing the electrically conductive tissue engaging plate, the electrically insulative, thermally non-degrading coating, and the jaw support into a jaw mold; and
introducing a liquid substance into the jaw mold and allowing the liquid substance to cure around the electrically conductive tissue engaging plate, the electrically insulative, thermally non-degrading coating and the jaw support to form an overmolding around the electrically conductive tissue engaging plate, around the electrically insulative, thermally non-degrading coating, and around the jaw support.

Abstract
A method of manufacturing a jaw member of an end effector assembly for use with an electrosurgical instrument is disclosed that includes the steps of providing an electrically conductive tissue engaging plate and a jaw support; covering one side of the electrically conductive tissue engaging plate with an electrically insulative, thermally non-degrading coating; placing and securing the electrically conductive tissue engaging plate and the jaw support into a jaw mold; and introducing a liquid substance into the jaw mold and allowing the liquid substance to cure around the electrically conductive tissue engaging plate and the jaw support. Alternatively, the method includes the steps of: providing an electrically conductive tissue engaging plate and a jaw support; covering one side of the electrically conductive tissue engaging plate with an electrically insulative, thermally non-degrading coating; and securing the side of the electrically conductive tissue engaging plate onto the jaw support with an adhesive.
