摘要：
A cutter for a blood vessel tissue harvesting instrument is disposed at the distal end of an insertion member. A cutter body projecting from the distal end of the insertion member includes a slit that extends from the distal end toward a base edge. High-frequency electrodes are disposed along the sides of the slit. A feeding mechanism has rotating surfaces which are rotated as a result of being pressed by the tissue, and which feed the tissue toward the base edge of the slit. The rotating surfaces are provided by two rotary members disposed opposite each other along the two side edges of the slit, respectively, so that the first and second rotating surfaces move in a direction from the opening of the slit toward the base edge of the slit.
