Abstract

A surgical patient support includes a foundation frame, a support top, and a brake system. The foundation frame includes a first column and a second column. The support top is coupled to the first column and the second column for rotation about a top axis extending along the length of the support top. A cervical traction system is also provided.

First claim

The invention claimed is:

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, and
a 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.

2. The surgical patient support of claim 1 , wherein the force provider comprises a weight coupled to the link.

3. The surgical patient support of claim 1 , wherein the traction attachment is configured to be coupled to a patient's head to provide cervical traction.

4. The surgical patient support of claim 1 , wherein the link includes a cable.

5. The surgical patient support of claim 1 , wherein the first axis of the first pulley coupled to the first column is oriented substantially vertically and the second axis of the second pulley coupled to the first column is oriented substantially horizontally.

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.

7. The surgical patient support of claim 6 , wherein the at least one weight comprises a plurality of weights.

8. The surgical patient support of claim 6 , wherein the attachment comprises a head wrap that is wrapped around the patient's head or a crown attachment that is coupled to the patient's skull with screws.

9. The surgical patient support of claim 6 , wherein the first column includes an upper telescopic segment and a lower telescopic segment and the tether extends through the upper telescopic segment.

10. The surgical patient support of claim 6 , wherein the tether includes a cable.

11. The surgical patient support of claim 6 , wherein the patient support frame is coupled to the rotatable shaft to rotate therewith.

12. The surgical patient support of claim 6 , further comprising at least one guide block located inside the first column and wherein the at least one guide block is configured to prevent the cable from disengaging from the first pulley.

13. The surgical patient support of claim 6 , further comprising casters coupled to the first and second columns, the casters being braked and released electrically, and an emergency manual caster release being coupled to the casters to release the brakes manually if electrical power is lost.

14. The surgical patient support of claim 6 , further comprising an H-bracket and pin to couple the patient support frame to the first column, the pin and the H-bracket each having a safety feature to prevent inadvertent decoupling of the patient support frame therefrom.

15. The surgical patient support of claim 14 , further comprising a slidable, floatable coupling member extending from a slot in an end frame member of the patient support frame and the slidable, floatable coupling member having a pin receiving bore to receive the pin.

16. The surgical patient support of claim 6 , further comprising an in-line rotational drive operable to provide powered rotation of the patient support frame relative to the first and second columns.

17. The surgical patient support of claim 16 , further comprising a knob coupled to a second shaft that is movable within a slot provided in a guide plate to move the rotational drive between a powered mode for powered rotation of the patient support frame and a manual mode for manual rotation of the patient support frame.

18. The surgical patient support of claim 6 , further comprising at least one patient support panel and a hinged clamp to secure the at least one patient support panel to the patient support frame, the hinged clamp including a jaw having at least one headed post and a flap hinged to the jaw, the flap having an opening with a wedge feature, the at least one headed post being received in the opening of the flap when the hinged clamp is in a closed position to secure the at least one patient support panel to the patient support frame.
