Abstract
The apparatus for the production of endochondral or osteochondral bores comprises a combination of a substantially hollow cylindrical sleeve (10), of which one end is formed as a circular cutting edge (11), with a flat borer (20) which is rotatably and axially displaceably arranged in the sleeve (10). Through pressing in of the cutting edge (11) into the tissue, advantageously only into the cartilage tissue, a tissue column is punched out which then is cut away and removed through screwing in of the flat borer (20). In this the boring is done up to the depth of the cutting edge (11) or deeper.
