ABSTRACT:
The device contains a rasp (2) corresponding to the implant shaft, which comprises a shaft body (4), which can be driven into the osseous tissue, and a neck part (5) protruding therefrom, which can be equipped with a test ball corresponding to the ball-and-socket joint, and a grip part (7) which can be coupled to the rasp (2) for the insertion and withdrawal of the shaft body (4). The grip part (7) contains a guide bush (10), which can be slipped onto the neck part (5), and a slip-on part (14) having a stop face which can be placed on a front support face of the neck part (5). On the grip part (7) is articulated a coupling part (11), which comprises a claw (27) which through a recess in the guide sleeve (10) can engage in a recess of the neck part (5) and can be disengaged from it. With this device, which can be manufactured from simple components which are easy to keep sterile, all stop, guide and clamping faces involved in the insertion and withdrawal of the shaft body (4) lie inside the enveloping shell face of the neck part (5) and as a result are protected from contact with fluid and bone particles.
