1. A surgical patient support comprising:
- a foundation frame including a first column and a hollow shaft supported by the first column for rotation relative thereto,a support top coupled to the shaft of the foundation frame to rotate with the shaft relative to the first column, anda surgical traction device including a traction attachment configured to be coupled to a patient during surgery, a force provider located outside the first column, and a link extending through the shaft from the traction attachment to the force provider, wherein the link is guided by a first pulley located inside the first column and coupled to the first column for rotation about a first axis and a second pulley located at least partially outside the first column and coupled to the first column for rotation about a second axis, wherein the second axis is substantially perpendicular to the first axis, wherein a first longitudinal axis of the link is substantially coincidental with a longitudinal axis of the hollow shaft, a second longitudinal axis of the link is substantially perpendicular to the longitudinal axis of the hollow shaft and the first longitudinal axis of the link, and a third longitudinal axis of the link is substantially perpendicular to the second longitudinal axis of the link.

6. A surgical patient support comprising:
-
a substantially vertical first column, a substantially vertical second column, a patient support frame situated between the first and second columns and configured to support a patient thereon, and a cervical traction device including an attachment configured to be coupled to the patient'"'"'s head, a tether extending from the attachment through the first column, a hollow rotatable shaft extending from the first column and wherein the tether is routed through the hollow rotatable shaft, and at least one weight located outside the first column and coupled to the tether to apply a traction force to the attachment via the tether, wherein the tether is guided by a first pulley located inside the first column and coupled to the first column for rotation about a first axis and a second pulley located at least partially outside the first column and coupled to the first column for rotation about a second axis, wherein the second axis is substantially perpendicular to the first axis, wherein a first longitudinal axis of the tether is substantially coincidental with a longitudinal axis of the hollow shaft, a second longitudinal axis of the tether is substantially perpendicular to the longitudinal axis of the hollow shaft and the first longitudinal axis of the tether, and a third longitudinal axis of the tether is substantially perpendicular to the second longitudinal axis of the tether. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
