This resection instrument (1) has a rigid outer pipe (4) which is releasably fastened on the front of the housing part (2) serving as a holding member and comprising a rotating drive unit (28). The outer pipe (4) is provided with an opening (7) in the vicinity of the front end-part and with a curved part (9) behind the opening (7). The inner pipe (6) is equipped with a cutting part (13) on the front end-part and releasably connected on its rear end-part with the rotating drive unit (28) for resection of body tissues by rotating the cutting part (13). The inner pipe (6) which has a flexible part (12) on at least one site corresponding to the abovementioned curved part (9) is guided through the outer pipe (4). <IMAGE>
