Abstract: The present application describes computer apparatus and software programs useful to the field of corrective spinal surgery. The apparatus and software implement and facilitate methods for assessing the degree of balance and alignment achieved through corrective measures applied to the spine prior to completing a surgical procedure. The apparatus and software facilitate pre-operative planning and virtual testing of the corrective measures to be applied. The apparatus and software further facilitate intra-operative reconciliation with the pre-operative plan prior to completing the surgery.

Abstract: An air operated double diaphragm includes an air valve, air chambers, a center section between the air chambers, pump chambers and diaphragms between the air and pump chambers harnessed together with a piston rod. The air valve includes a statically dissipative body having a bore therein with a statically insulative liner in the bore. The statically insulative liner is fully enclosed within the statically dissipative body. A valve element is slidably positioned in the liner. The liner includes annular tenons to mate with annular mortises in the statically dissipative body and an end cap is used to close the valve cylinder.
