Patent ID: 8016821

Claim:
A living body tissue harvesting apparatus for cutting a living body tissue, the living body tissue harvesting apparatus comprising: a plate-shaped cutter body made of an insulating member, the cutter body including a base end part and a tip part,; a plate-shaped heat-resistant member connected to the cutter body, the plate-shaped heat-resistant member including a first surface and a second surface; an active electrode for supplying electric energy, the active electrode being arranged on a first surface side of the heat-resistant member and including a base end part and a tip part; a return electrode for receiving electric energy from the active electrode, the return electrode being arranged on a second surface side of the heat-resistant member, wherein the heat-resistant member further includes: a first groove part for guiding the living body tissue from the tip part of the cutter body, and a second groove part for reducing heat conduction that is formed on the first surface side of the heat-resistant member such as to surround a tip part of the active electrode which protrudes from the first groove part.
