Abstract

This invention is a reusable electrosurgical return electrode pad (20) for use with electrosurgery.
In one embodiment it includes a presentation or working surface area lying in a range of from about 11 squares inches to 1,500 square inches. In another the working surface is at least as large as that of a projection of about half of the profile of the trunk of a patient. In yet another, it includes a working surface area at least as large as that of a projection of the profile of both the trunk and legs of a patient. It is adapted for disposition on the working surface of an operating table (40) or dentist's chair (50) immediately underlying a patient during electrosurgery.
By presenting a very large working surface area, the need for direct contact or contact through conducting jells is eliminated. Through employment of washable surface areas, it is made readily cleanable and reusable. Through the selection of resistance characteristics for the electrode materials of the principal body of the electrode, and through tailoring of electrode geometries, it is made self-limiting as to- current density and temperature rise so as to prevent patient trauma. An optional sleeve is provided for cooperative use with the electrode.
