The positioning device (10) comprises two frame parts, the holding frame (14) and the bearing frame, both designed with L-shaped lateral areas (18), which can be rotated around a bolt (22) guided through both frame parts. A sleeve, holding the surgical tool (88), is swivel mounted to the rear of the bearing frame and can be swiveled to the sides as well as back and forth, facilitating a precise guidance of the tool (88, 90). |
