Abstract
A device (10) serves for guiding a drilling tool (56) for making a bore (58) into a bone (50), intersecting an already existing first bore (54). The device (10) has a first rod-shaped body (12), the first end of which can be introduced into the already existing first bore (54) in the bone (50). Its second end is provided with an arm, which bears a guide (30) for the drilling tool (56), the longitudinal axis of which intersects the rod-shaped body (12) in the region of its first end. The arm has an arcuate portion (26), along which the guide (30) for the drilling tool (56) can be moved. An opening (16) is provided in the rod-shaped body allowing the drilling tool (56) to pass said rod-shaped body.
