<p>In order to improve a surgical positioning and holding device for positioning and holding a guide for a surgical machining tool, with at least one fastening element for fixation to a bone to be machined and with a platform held on the at least one fastening element so as to hold the guide, so that anchoring surfaces may be prepared in a simple manner and with a high degree of precision on a bone to be machined, it is proposed that the guide be mounted for rotation about a first axis of rotation and be designed such that at least one surface concentric with the first axis of rotation may be prepared with the machining tool guided in or held on the guide.</p> |
