The valve body can be connected releasably as a completely assembled valve body unit to one end of the cannula tube. The valve of the valve body ensures a tight closure of the cannula tube at said one end, but allows an instrument to be passed through the valve body unit and the cannula.

A biodegradable fixation element is provided for anchoring a transplant on bone. A rigid body is made of a biodegradable material, said body having an outer side and a hollow interior surrounded by a wall of said body. Numerous perforations are provided in said wall of said body for allowing growth of bone material into said interior of said body via said numerous perforations. It is proposed that the perforations are formed between said anchoring members and said perforations are formed as holes passing through said wall of said body (FIG.).
