ABSTRACT:
A device and method for automatically verifying, calibrating and surveying a navigable surgical instrument, wherein by means of a scanning device, the geometry of the instrument, in particular the shape of the functional elements (e.g., tips) and their spatial position with respect to an attachable reference system, are detected. By means of a data processing unit, a three-dimensional model of the instrument is calculated from the detected information concerning the geometry of the instrument including the reference system, wherein verification, calibration or surveying is performed with the aid of the ascertained information concerning the geometry of the instrument.
