DEVICE FOR INTRAOPERATIVE IMAGE-GUIDED NAVIGATION DURING SURGICAL INTERVENTIONS IN THE VICINITY OF THE SPINE AND THE ADJOINING THORACIC, PELVIS OR HEAD AREA

摘要

The invention relates to a device (1) for intraoperative, image-controlled navigation during surgical interventions in the region of the spine and / or in the adjacent thoracic, pelvic or head region, comprising a plurality of non-X-ray-based detection devices (11-17), in each case are formed distributed around at least one object to be operated (2) to be arranged and intraoperatively capture image and position data in real time, each information about at least the outer contour of at least a portion of the object to be operated (2) and on the location of the sub-area relative to the respective detection device (11-17). Furthermore, a position-determining device (20) is provided for determining the position of the respective detection devices (11-17) relative to a stationary reference system (30) and a data processing device (40) operatively connected to the detection devices (11-17) and the position-determining device (20) is formed, based on the respective image and position data of the detection means (11-17) and the position data of the position determining means (20) on the stationary reference system (30) referenced, virtual, preferably three-dimensional real-time image (41) of the object to be operated (2), which is displayed on an image display device (50). According to the invention, at least one of the detection devices (13-17) at least one detection means (13.1-17.1), which is adapted to be arranged inside the body to capture image data, the information about at least the outer contour of at least one Body interior facing portion of the object (2).
