"Ceramic Coated Medical And Biopsy Appliances And Fabrication Method Therefor"

Abstract: Ceramic-coated medical appliance or biopsy appliance is 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 cello 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 p of 105 ?-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.
