Abstract
An electrode for a high-frequency medical device in which a coating film is formed on at least a part of a surface of a treatment section of the medical device, wherein the coating film includes a silicone resin, and at least one type of filler having conductivity. Particles of the fillers are fusion-bonded to each other to form a conductive path, and/or a particle of the filler and an electrode substrate disposed on a surface of the treatment section are fusion-bonded to form a conductive path.
Claims6
An electrode for a high-frequency medical device, the electrode comprising:
- a treatment section;
- and
- a coating film formed on at least a part of a surface of the treatment section, wherein the coating film comprises:
- a silicone resin, and
- at least one type of filler having conductivity,
- wherein:
- particles of the filler are fusion-bonded to each other to form a conductive path, and
- the particles of the filler and an electrode substrate disposed on a surface of the treatment section are fusion-bonded to form a conductive path;
- wherein the particles have a shape with corners and the corners are bonded together by the fusion-bonding.
An electrode for a high-frequency medical device comprising:
- a treatment section;
- and
- a coating film formed on at least a portion of a surface of the treatment section, wherein the coating film is a conductive anti-adhesion film, the coating comprises:
- a silicone resin;
- and
- a conductive filler comprising a plurality of conductive particles,
- wherein the plurality of conductive particles are fusion-bonded to each other, or to the conductive filler and an electrode substrate located on the surface of the treatment section, to form a conductive path,
- an electrode surface of the coating film has an exposed portion where the conductive filler is exposed from the silicone resin, and a smooth surface of the silicone resin excluding the exposed portion,
- an area of the exposed portion in a plan view is smaller than a surface area of the silicone resin,
- the conductive filler comprises two or more particles with different particle sizes, and
- a proportion of the conductive filler with smaller particle sizes is higher near the electrode substrate.
