摘要

A first frame (100) to be attached to the bone and a second frame (200) for holding and guiding the tool (210) are positioned on both sides of the hydraulically or pneumatically operated adjusting unit (300). The fluid or the air are guided through tubes (334, 336) provided with regulating valves (310, 320). The tool can be a block (210) with a slot (214) for the insertion of the cutting blade. A reference element (400) clipped to the tool (210) against the forces of a spring (430) is fitted with three passive markers (420a, 420b, 420c).
