Apparatus and method for pre-operative selection and determining the position of an endoprosthesis

摘要

The invention provides the device and an associated method for pre-operative selecting and determining a position of an endoprosthesis with a stationary first rear projection surface (1) with variable opacity and a movable second rear projection surface (2) which, with respect to a rear projection in front of the first rear projection surface (1) is located, on. The device also comprises a first projection unit (11) for generating at least a first projection (6) of the region of an object, in which the endoprosthesis is to be fitted to the first, the rear projection surface (1) and a second projection unit (12) for generating at least a second projection (7) of the endoprosthesis to the second rear projection surface (2), wherein the scaling of the first and second projection (6, 7) is the same. The apparatus further comprises a displacement unit (8) for displacing and / or rotation of the second rear projection surface (2) with respect to the first rear projection surface (1) and a in the displacement unit (8), which are arranged in a feedback unit (3), by means of which the for the displacement of the second rear projection surface (2) in the case of the choice and positioning of the endoprosthesis necessary force to be changed in such a manner that a user receives a tactile feedback. The invention offers the advantage of an intuitive haptic control for the selection and the position of the planning of an endoprosthesis.
