The invention relates to a device for treating the human and/or animal body, for example a core drill, especially an intramedullary reamer for tubular bones, which has a drill head (12). Said drill head (12) is connected to a flexible shaft (14) which is in turn connected by a shank (16) to a drilling machine. The core drill also has a rinsing unit (18) by which means drilled material is removed in the area of the drill head (12). The rinsing unit (18 ) is connected to a rinsing channel (30) for this purpose, said rinsing channe l being configured between the bore and the outside diameter of the flexible shaft (14). The drill head (12) has slits (34) which are connected to an inn er cavity (36) of the drill head (12). Said cavity (36) is in turn connected to an inner channel (40) provided in the flexible shaft (14). The rinsing mediu m is guided into a rinsing head (42) through said inner channel. In the rinsin g head (42), the rinsing medium enters a ring-shaped channel (58) through slit s (60) provided in the flexible shaft (14). Said ring-shaped channel (58) is connected to a channel (54) to a which a suction device is connected by flexible tubing (56).
