Abstract
For use in back surgery, a known kneeling attachment to an operating table has a platform on which a patient kneels with the torso positioned over one end of an operating table and the buttocks resting against the padded crosspiece of a rigid U-shaped yoke. The invention concerns a substantially rectangular rigid frame which can be mounted on the yoke with an outboard crossarm of the frame attached to the crosspiece of the yoke and the inboard end of the frame attached to the arms of the yoke. The frame is useful for supporting surgical instruments such as retractors at a surgical wound, in particular a retraction device that a surgeon can adjust with one hand, even without looking. The frame also makes possible a new surgical procedure by which a dislocated vertebra can be moved into position by a lifting mechanism suspended from the frame.
