Title:
SURGICAL ELECTRODE HAVING SURFACE TREATMENT COATING
Document Type and Number:
WIPO Patent Application WO/2020/027341
Kind Code:
A1
Abstract:
A surgical electrode, wherein: a distal end portion, which is capable of emitting a high frequency, has a surface treatment coating that includes a first film and a second film in the stated order; the first film is formed by bringing a surface treatment agent (X) into contact with at least all or part of the surface of the distal end portion, the surface treatment agent containing at least a compound having an amino group; the second film is forming by bringing a surface treatment agent (Y) into contact with all or part of the surface of the first film, the surface treatment agent containing a silicone resin (A), a compound (B) that includes a metal element selected from titanium, platinum, rhodium, and palladium, and an aromatic hydrocarbon solvent (C); (I) the silicone resin content is within a range of 90-99.9% by mass relative to the total solids fraction mass of the silicone resin and the compound; and (II) the ratio (BM/AM) of the mass of the silicone resin (AM) and the mass of the compound (BM) is within a range of 0.001-0.111.
