摘要
A device for the introduction of an annular pocket hole bore (11) in the femoral condyle (2) of the human body by means of a tubular and can be driven to rotate about its longitudinal axis of the hollow drilling - or hollow grinding tool (6), as well as for the production of the resulting cylindrical core (5) as a bone dowel, characterized by the,that a femurales targeting apparatus (1) with a sight tube (3) is provided, the sight tube (3) with its ventral end on the femoral condyle (2) can be fixed,that the tool (6) in a tubular guide sleeve (7) is received, which in the sight tube (3) together with the tool (6) is displaceable,that a in accordance with the desired depth of the blind hole in the femoral condyle (2) dimensioned spacer bush (9) so as to be replaceable on the guide bush (7) for the tool (6) of up to a fixed position is pushed, as a result of which at the distance bush (9) a stop (14) for limiting the depth of the blind bore (11) is formed, which the dorsal end of the target tube (3) as a counter stop (15) associated with it.that the cylindrical core (5) by rotation about its cylinder axis relative to the femoral condyle (2) and at the end face of the severed from the femoral condyle (2) can be extracted.
