ABSTRACT:
A spinal positioning frame mounted atop an operating table for lateral, longitudinal and pivotal adjustment allows optimal patient positioning. A yoke mounted in a rectangular frame for reciprocal sliding movement is driven by a pneumatically controlled electric linear actuator which may be driven in an emergency by blowing into pneumatic control lines. A pair of spaced parallel flexible steel flex strips connect juxtaposed anterior and posterior fulcrum plates pivotally mounted adjacent opposite ends of the frame. A pair of patient support pads are adjustably secured by cooperating hook and loop pile fasteners to respective pad mounting plates. Slots in the pad mounting plates receive cam lock fasteners which adjustably secure the pad mounting plates to the flex strips. The actuator causes the flex strips and pads to bow convexly upwardly, while a meter indicates the degree of flex, allowing precise regulation of spinal curvature to afford maximum lumbar access. An X-ray transparent bridge pivotally secured beneath the fulcrum plates provides support for a patient's abdomen and allows insertion of an X-ray cassette beneath the bridge for precise determination and documentation of surgical coordinates and results without removing the patient from the spinal positioning frame.
