초록 ▼

A reusable electrosurgical return electrode pad for use with electrosurgery. In one embodiment it includes a presentation or working surface area lying in the range of from about 11 to about 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 or dentist's chair immediately underlying a patient during electrosurgery. By presenting a very large 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; and through the inclusion of capacitive. coupling and selection of impedance characteristics for the materials and 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.]1. A reusable electrosurgical return electrode comprising:(a) a sheet of material having(i) a first layer of predetermined limited electrical conductivity;(ii) a second layer of dielectric material having a predetermined capacitive reactance, said second layer contacting and overlying said first layer; and(b) connecting means for making electrical connection to said sheet, wherein said predetermined limited electrical conductivity and said predetermined capacitive reactance automatically and continuously limit the density of electrosurgical current flowing through said electrode to less than 100 milliamperes per square inch.
