Device for determining inclination of e.g. hinge implant relative to bone of patient, has data processing unit including data connection to camera for determination of position by detecting instrument and determining orientation in image

摘要

The device has a camera (3) for recording an image of a medical instrument (11). A fastening unit (6) fastens the camera at a positioning device (12) e.g. template, such that the camera is directed on the instrument. A data processing unit e.g. computer, includes a data connection to the camera for determination of a position in form of an inclination of the instrument by detecting the instrument, determining an orientation in the image, and computing the inclination of the instrument relative to the positioning device based on the orientation in the image. Independent claims are also included for the following: (1) an arrangement for determining a position of a medical instrument (2) a method for using a device for determining a position of a medical instrument (3) a method for determining a position of a medical instrument (4) a computer program product comprising instructions for performing a method for determining a position of a medical instrument (5) a computer readable medium comprising instructions for performing a method for determining a position of a medical instrument.
