At the rear end, the shaft section 16 continues into a disk-shaped grip part 19, the circumferential surface of which is provided with a profile, for example, knurling 20. The grip part 19 is flattened on one side, with the flattened part 21 extending over, for example, an angle of almost 90° in the circumferential direction.
The operator then sets the desired drilling depth individually for each hole to be drilled by turning the adjusting part 7 in relation to the bearing part 6. The spacing of the grip part 19 from the tips 9 is thereby adjusted. By feeling the flattened part 21, the operator can sense the number of rotations of the adjusting part 7. The fixing of the adjusting part 7 by the detent body 25 while it is being turned in the bearing part 6 is also an orientation aid to him as renewed fixing always occurs after a rotation through 180°.
1. Drilling jig for a surgical drilling tool, comprising:
two sleeves of identical design alongside each other on a common holder;
each sleeve being mounted on said holder so as to be pivotable in relation to each other about an axis of rotation extending perpendicular to their longitudinal axis;
each of said sleeves being positionable with its front end on a bone, into which the drilling tool is screwable, thereby passing through the interior of said sleeve, and at the rear end a stop surface for a stop of said drilling tool to rest thereon, said stop delimiting the depth to which said drilling tool penetrates said sleeve; and
means for adjusting the spacing between said stop surface and said front end of said sleeve, wherein:
said sleeve is of two-part design and includes a bearing part and an adjusting part, in that said bearing part carries said front end and said adjusting part carries said stop surface, and in that said bearing part and said adjusting part are screwed to each other in such a way that the spacing between said stop surface and said front end of said sleeve is adjustable by turning said adjusting part in relation to said bearing part.
2. Drilling jig as defined in claim 1, characterized in that said adjusting part is screwed into said bearing part.
