摘要：
A treatment electrode of a resectoscope apparatus is substantially semicircular-shaped. A length a of a first segment and a length b of a second segment satisfy a relationship of (a>2·b). The first segment is in parallel with the plane on which a parallel lead member exists and has the maximum width of the treatment electrode. The second segment is vertical to the first segment and has the maximum distance between an intersection to the first segment and an intersection to the treatment electrode.
