Abstract: A partially coated electrosurgical electrode has a portion of a medical grade metallic material as a substrate for energy application. Conductive sites of metallic material or alloys thereof pass energy through peaks that define valleys nearby. A partial coating in the valleys has a low surface free energy. A treated surface across the peaks and generally over the filled valleys is relatively smooth for non stick characteristics during application of electrosurgery to tissue and bodily fluids. Openings in the treated surface through the partial coating are at the peaks of conductive sites to expose the metallic material or alloys thereof. The partial coating is a fluorinated polymer. The treated surface is a relatively even level that is not flat. The metallic material substrate is an alloy of stainless steel or nickel chrome. A mechanically deformed surface finish, plasma or vapor deposition on the substrate forms the conductive sites. A method of manufacturing the electrode has steps including preparing the metallic conductor, making it with the conductive material having peaks above the valleys as conductive sites, applying the partial coating to it and treating the surface across the peaks and generally over the filled valleys of the partially coated electrically conductive electrode. Locating the openings among the valleys is a step. Treating may be mass finishing, such as vibratory or tumbling the partially coated electrodes with or without abrasive material media or polishing, buffing, surface grinding, abrasive belt grinding or sanding with abrasive material. Making the peaks and valleys can be by stamping, coining, burnishing, embossing, threading, tumbling, vibrating, shot peening, wire brushing, grit blasting, thermal spraying, with powder, with wire supplied to melt and be distributed, or with high velocity oxygen fuel and a nickel, cobalt alloy, stainless steel or a nickel chrome alloy. A manufacturing method for the electrode has coating a strip of metal with the low surface energy polymer and forming it in a stamping operation with a raw metal edge.

Abstract: An electrosurgical tip (10) for the application of electromagnetic energy in either a monopolar or a bipolar circuit through the tissue and the bodily fluids of an animal or human (13) has a metallic electrically and thermally conductive electrode for connection to an electrosurgical generator proximally and for transmission of the electromagnetic electrosurgical energy (12) to the tissue and the bodily fluids of the animal or human (13) distally. A sheath (18) of heat shrinkable fluorinated polymeric substance is an electrical and thermal insulator (14) held about the electrode for preventing the flow of electromagnetic and thermal energy from the metallic electrically and thermally conductive electrode to the tissue and the bodily fluids. A smooth surface of the sheath (18) contacts the tissue and the bodily fluids and has a low surface free energy. Openings (16) through the sheath (18) extend from the electrode to the surface (15) for permitting the passage of energy. A wall (17) of the sheath (18) is of a thickness adequate to space the electrode from substantially any contact with the tissue and isolate heat due to the arcs. A ceramic substance (19) is an electrical and thermal insulator (14) about the conductive electrode for preventing the energy flow. A method of making the tip includes covering the electrode with the insulator, isolating physically the heat generated due to the passage of energy. A method of using the tip places the surface (15) in close proximity to the tissue and the bodily fluids, transmits the electromagnetic energy through the openings (16), allows cleaning tissue and bodily fluids from the surface (15). The use includes first passing energy through openings (16) in a wall (17) of electrical and thermal insulation and application of electromagnetic energy by either a monopolar or a bipolar circuit relative to the tissue and the bodily fluids of an animal or human (13).

Abstract: A design and method of manufacture are disclosed for an electrosurgical electrode (10) with a silicone coating. The coating resists the build-up 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 (15) 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 (10) coatings may include silicone elastomers (11) in the form of adhesives, dispersions, or liquid rubbers. The coating composition may also contain adhesion promoters, heat stabilizers, plasticizers, release enhancers, cross-linking agents, and colorants. Several methods of manufacture are illustrated by way of examples.
