Device for determining the position of a cutting guide

摘要

The apparatus (20) to determine the position of a cutting block (1), used in orthopedic surgery to cut through a bone for an implant, has a positioning unit (21) with at least one reference point (22a-22c) with reflecting surfaces to register the spatial position. To determine the position, a defining reference element (13) establishes the laying plane with a plate inserted into the cutting block, working with at least one pressure element (14) with a spring (12).
