摘要:
The invention relates to an aiming device (100) for boring a hole in a region of a bone (300) that lies in the vicinity of a joint. Said device consists of a U-shaped bow (110) comprising at least one contact element (120) on one end and on the other end of the bow (110) a screw spindle (130) that can be displaced in the direction of, or in the opposite direction to the contact element (120), said spindle comprising a rotary grip (132) for clamping the device (100) on the region in the vicinity of the joint. The device also comprises a bore bushing (140), which can be placed on and removed from the end comprising the contact element (120). The compression of the bone that is generated by the bow (110) is maintained after the removal of the bore bushing (140) for the insertion of the bone screw.
