Device and method for measuring geometric properties of medical tools, in particular for automated verification, calibration and gauging of tools for computer assisted surgery

摘要

The measuring device has a measuring unit, which is formed to measure the relative position between a part of a medicine-technical treatment device and another part of the medicine-technical treatment device. A time recording unit (880) is formed to record the time of the measurement. A Radio-frequency identificationwriting utensil that is formed a time, which is based on the recorded time, to write in a radio-frequency identification transponder of the medicine-technical treatment device. Independent claims are also included for the following: (1) a navigation system for navigate a medicine-technical treatment device, which has a detection device for detecting a reference system (2) a method for measuring geometrical characteristics of the medicine-technical treatment device, which involves measuring relative position two parts of the medicine-technical treatment device (3) a computer program, which is loaded in a computer or runs on a computer (4) a method for the planning of a surgical interference or for the execution of a surgical interference.
