Patent number: 11510738Abstract: A surgical instrument system for treatment of an anatomical structure comprises an instrument and/or a patient specific instrument. The instrument and/or the patient specific instrument comprises an integrated measurement system for tracking the instrument and/or the patient specific instrument relative to the anatomical structure. The integrated measurement system comprises a tracking system, which comprises a shadow imaging tracking system comprising an optical source, a shadow-generating device and a patient specific instrument sensor. An initial position of the instrument or the patient specific instrument is registerable by the patient specific instrument sensor. The shadow-generating device is arranged between the optical source and the imaging device for generating a shadow. The shadow imaging tracking system is configured to compute the elevation of the source from the pattern the shadow casts on the surface of the imaging device.Type: GrantFiled: April 26, 2018Date of Patent: November 29, 2022Assignee: MEDIVATION AGInventors: Jan Stifter, Tobias Schwägli
