Patent attributes
The invention relates to an implant layer positioning system comprising a device that can be fixed to a bone section and is used to plan the positioning of implants in order to enable corrective operations to be performed on the bone with optimum bone contact. Said device reproduces the geometry of at least one section of the implant and can be freely oriented by the operator towards accessible parts of the bone. The inventive system also comprises a control unit which virtually evaluates the relevant implant parts, on the basis of the navigation data of the tracked device and the data input of the planned corrective operation, in the form of three-dimensional geometry bodies in fluoroscopy sketches or other referenced image or geometry data. Once the planned proceedings have been inputted, the control unit of the navigation system can virtually merge the corresponding position of all implant parts with the referenced image or geometry data of the patient in a three-dimensional manner by means of corresponding computational algorithms, and once the device has been oriented, the control unit can store the position of said device with all related dependent positions of the implant parts planned at the same time, and all of the planning information can be made available for use with navigated tools.
