Abstract: The invention relates to a medical instrument identification setup, comprising a sensor carrier, configured to be removably arranged in a lumen of a medical instrument. The sensor carrier has at least two localizers, the localizers each being configured for providing a sensor signal representing position and orientation of the respective localizer. The medical instrument identification setup further comprises a position detection system that is configured for determining position and orientation of the at least two localizers in a position detection system's coordinate system from received sensor signals. The medical instrument identification setup has a calibration device and a calibration unit, the calibration device being configured such that its position and orientation in the position detection system's coordinate system can be determined by the position detection system.

Abstract: The invention relates to a surgical kit, for performing minimally invasive spine surgery. The surgical kit comprises a position detection system, configured for detecting position and orientation of localizers from received sensor signals in the position detection system's coordinate system. The surgical kit also comprises a sensor carrier, configured to be removably arranged in a lumen of a medical instrument, the sensor carrier having at least two localizers, the localizers each being configured for providing a sensor signal representing position and orientation of the respective localizer. Furthermore, the surgical kit comprises a plurality of medical instruments having a lumen in which the sensor carrier can be removably arranged for connecting the respective medical instrument to the position detection system.
