ABSTRACT:
A resectoscope comprises a plurality of sheaths having different inner diameters, a plurality of optical observation tubes having different view field directions and insertible into the corresponding sheaths, and a plurality of electrode rods which are provided with electrode sections bent at different angles for different view field directions and having different sizes and which are insertible into the corresponding sheaths. A resectoscope is assembled from one selected sheath, one selected optical observation tube and one selected electrode rod. In order to facilitate the correct assembly of these various parts, the electrode rods have a first color mark capable of distinguishing the different angles of the electrode sections and a second color mark capable of distinguishing the different sizes of the electrode sections. The respective sheaths have a third color mark capable of distinguishing their different inner diameters. The optical observation tubes have a fourth color mark capable of distinguishing their different view field directions [, and the]. The assembled electroscope combines an electrode rod, sheath and optical observation tube having suitably matching color marks.
