A reusable electrosurgical return electrode pad for use with electrosurgery. In one embodiment it includes a presentation or working surface area at lying in a range of from about 100 to about 20,000 square centimeters. 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 or dentist's chair immediately underlying a patient during electrosurgery. By presenting a very large working surface area, the need for direct contact or contact through conducting gels is eliminated; through employment of washable surface areas, it is made readily cleanable and reusable; and 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.

[ What is claimed is:] [1.] A reusable electrosurgical return electrode comprising a sheet of material having a predetermined limited electrical conductivity, said sheet having connection means for making electrical connection to said sheet; said sheet having a first major surface including a working surface adapted for disposition immediately adjacent the trunk region of a patient positioned for electrosurgery, wherein said area of said working surface is at least substantially equal to or greater than the projected area of the entire trunk region of said patient.
