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 single-handle unlock for the support top is also provided.

First claim

The invention claimed is:

1. A bracket for coupling a patient support top to a spine surgery table having a foundation frame including a coupler block that includes first and second retainer pegs extending therefrom in opposite directions, the bracket comprising:
a base member,
a first coupling member coupled to the base member and extending substantially perpendicular to the base member, the first coupling member formed to include a first retainer slot adapted to receive the first retainer peg therein when the bracket is coupled to the coupler block,
a second coupling member coupled to the base member and extending substantially perpendicular to the base member, the second coupling member formed to include a second retainer slot adapted to receive the second retainer peg of the coupler block when the bracket is coupled to the coupler block, and
a secondary retainer adapted to couple the first coupling member to the coupler block, the first and second coupling members being adapted to be pivotable relative to the retainer pegs when the secondary retainer is decoupled from the first coupling member and from the coupler block, wherein the first and second coupling members are adapted to be prevented from pivoting relative to the retainer pegs when the secondary retainer is coupled to the first coupling member and coupled to the coupler block, wherein the first coupling member includes a first hole therethrough and the secondary retainer includes a pin that is adapted to extend through the first hole and into a pin-receiving bore formed in the coupler block.

2. The bracket of claim 1 , wherein the pin-receiving bore extends all the way through the coupler block and the second coupling member includes a second hole, the pin also extending through the second hole.

3. The bracket of claim 2 , wherein the pin is substantially parallel with the retainer pegs when the pin is received in the first hole, the pin-receiving bore, and the second hole.

4. The bracket of claim 2 , wherein the pin is substantially parallel with the base member when the pin is received in the first hole, the pin-receiving bore, and the second hole.

5. The bracket of claim 2 , wherein end surfaces of the first and second coupling members are adapted to be flush with respective surfaces of first and second extensions of the coupler block when the first and second retainer pegs are received in the first and second retainer slots and the pin is received in the first hole, the pin-receiving bore, and the second hole.

6. The bracket of claim 5 , wherein the pin is adapted to be substantially parallel with the first and second extensions of the coupler block when the pin is received in the first hole, the pin-receiving bore, and the second hole.

7. The bracket of claim 1 , wherein the base member is generally cylindrical in shape.

8. The bracket of claim 1 , wherein the first coupling member has a first series of holes and the second coupling member has a second series of holes, each hole of the first series of holes being aligned with a respective hole of the second series of holes to provide the bracket with a plurality of patient support top coupling locations.

9. The bracket of claim 8 , further comprising a cross pin adapted for insertion through one of the holes of the first series of holes, through a pin-receiving member of the patient support top, and through one of the holes of the second series of holes thereby to couple the patient support top to the bracket.

10. A surgical patient support apparatus comprising:
a foundation frame having a first lift column, a coupler block mounted for rotation to an upper region of the first lift column, and first and second retainer pegs extending from the coupler block in opposite directions,
a patient support top,
a bracket configured to couple an end of the patient support top to the coupler block, the bracket being attachable to and detachable from the coupler block, the bracket comprising
a base member,
a first coupling member coupled to the base member and extending substantially perpendicular to the base member, the first coupling member formed to include a first retainer slot configured to receive the first retainer peg therein when the bracket is coupled to the coupler block, and
a second coupling member coupled to the base member and extending substantially perpendicular to the base member, the second coupling member formed to include a second retainer slot adapted to receive the second retainer peg of the coupler block when the bracket is coupled to the coupler block, and

a secondary retainer to couple the bracket to the coupler block, the first and second coupling members being pivotable relative to the retainer pegs when the secondary retainer is decoupled from the bracket and from the coupler block, wherein the bracket is prevented from pivoting relative to the retainer pegs when the secondary retainer is coupled to the bracket and coupled to the coupler block, wherein the first coupling member includes a first hole therethrough and the secondary retainer includes a pin that extends through the first hole and into a pin-receiving bore formed in the coupler block.

11. The surgical patient support apparatus of claim 10 , wherein the pin-receiving bore extends all the way through the coupler block and the second coupling member includes a second hole, the pin also extending through the second hole.

12. The surgical patient support apparatus of claim 11 , wherein the pin is substantially parallel with the retainer pegs when the pin is received in the first hole, the pin-receiving bore, and the second hole.

13. The surgical patient support apparatus of claim 11 , wherein the coupler block includes first and second extensions that protrude from opposite sides of a main body of the coupler block in parallel relation with the first and second retainer pegs and wherein end surfaces of the first and second coupling members are flush with respective surfaces of the first and second extensions when the first and second retainer pegs are received in the first and second retainer slots and the pin is received in the first hole, the pin-receiving bore, and the second hole.

14. The surgical patient support apparatus of claim 10 , wherein the first coupling member has a first series of holes and the second coupling member has a second series of holes, each hole of the first series of holes being aligned with a respective hole of the second series of holes to provide the bracket with a plurality of patient support top coupling locations and further comprising a cross pin for insertion through one of the holes of the first series of holes, through a pin-receiving member of the patient support top, and through one of the holes of the second series of holes thereby to couple the patient support top to the bracket.

15. The surgical patient support apparatus of claim 10 , further comprising means for applying traction to a head of a patient supported on the patient support top.

16. The surgical patient support apparatus of claim 10 , further comprising casters coupled to the foundation frame, 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.

17. The surgical patient support apparatus of claim 10 , further comprising a second bracket configured to detachably couple to the coupler block, the second bracket having a third coupling member that is aligned with the first coupling member and that extends from the coupler block in an opposite direction from the first
