The spiral blade is removable attached to the front end of the mandrel. The peripheral surfaces of the mandrel and the through hole of the guide sleeve have engaging mechanisms that interact with each other in such a way that the mandrel can be moved in the through hole of the guide sleeve only in a screw-like manner. An axially movable tissue-protective sleeve can be attached coaxially in relation to the mandre l.
