The tool can be a chisel (1) with an oval cutting edge (4) at the front, a rectangular hitting plate (3) at the back, and a slightly bent shaft (2) with a rectangular cross section between them. Several openings (7) in the rear section (6) of the shaft (2) facilitate the joining of an adapter piece (8) holding a marker element (21) indicating the position of the tool (1) in relation to the bone. The adapter (8) is block-shaped with a groove (9) at the front for the insertion of the shaft (2) and fitted with a projection (10, 13) to be inserted into the appropriate opening (7). The connection is secured with a locking unit (12, 14). |
