Abstract
Providing a ceramic-coated medical appliance quite excellent in insulating performance which has no negative effects on tissues or cells of an organism subjected to surgery; a ceramic-coated genetic control needle which has no risk of breaking during use nor no unfavorable effects, such as destruction or tear-off, on sliced tissues or tissue areas around the needle at site of penetration into a lesion and which cuts off a cell nucleus or injects an immunological solution into the nucleus without causing any negative effects on tissues around the penetrated needle; and a fabrication method for the same.
Specifically, in the ceramic-coated medial needle, genetic control needle, biopsy forceps and medical appliances such as forceps, surgical scissors and surgical knife, an insulating ceramic film having a resistance ρ of 105 Ω·m or more is formed, by dry plating, at least on a portion, a part or the whole of an outer and/or an inner surface of a metal needle that directly contact an organism, or cells or cell nuclei thereof.
