Abstract

This invention is a vertebral triplaner alignment facilitator to enable a surgeon to make minute vertebrae adjustments during spinal surgery. The vertebral triplaner alignment facilitator includes a support device which is adapted to support a tensioning device. The support device includes a support structure and a gurney. The gurney is adapted to support the tensioning device, while the support structure supports the gurney above a patient. The support structure typically includes a support rod, a sacral bridge, and adjustment rods. The support rod may be adapted to connect to a retractor. The sacral bridge may be adapted to sit on the iliac spines or crests of the pelvis. The adjustment rods movably engage the support rod and the sacral bridge such that the adjustment rods can move laterally over the patient and longitudinally relative to the retractor. A plurality of gurneys engage the adjustment rods such that they may move along the adjustment rods and may pivot about the adjustment rods. Each gurney tracks and pivots independently of the other gurneys, as does each adjustment rod. Each gurney is adapted to support the tensioning device such that the tensioning device may pivot about an axis perpendicular to the gurney. Thus, the alignment facilitator allows the tensioning device to be moved through multiple translational and to rotational degrees of freedom.
