Abstract
A design and method of manufacture is disclosed for an electrosurgical electrode with a silicone coating. The coating resists the buildup of eschar. The silicone material is thick enough in the flat area of the blade to withstand the electrosurgical voltage without breakdown. The electrosurgical current path is primarily through the blade edges and tip. The flat of the blade remains insulated under most conditions. The relatively thick coating also provides high tear strength and added durability. The composition of the electrode coatings may include silicone elastomers in the form of adhesives, dispersions, or liquid rubbers. The coating composition may also contain adhesion promoters, heat stabilizers, plasticizers, release enhancers, crosslinking agents, and colorants. Several methods of manufacture are illustrated by way of examples.
