Knochenfräser

摘要

The invention relates to a bone cutter (10b, 10c, 10d) for the precise preparation of bones, comprising a cutter head (12b, 12c, 12d) and a drive shaft (14) connected to the cutter head (12b, 12c, 12d). The problem with conventional bone cutters is that the operational field and the drive shaft can overlap. This can lead to directional instability or wrong directional cutting surfaces. In order to solve this problem the drive shaft (14) is used as a guiding device in the bone and an indentation (20b, 20c, 20d) is placed on the drive shaft side of the cutter head (12b, 12c, 12d).
