Abstract

A patient support apparatus for spine surgery includes first and second lift columns. A patient support frame extends between the first and second lift columns. The patient support frame has a first section to support a torso of a patient and a beam that extends from the first section. The beam is coupled to a foot end region of the first section about midway between opposite sides of the first section. A first set of leg supports are located adjacent a first side of the beam and a second set of leg supports are located adjacent a second side of the beam. The first and second sets of leg supports are independently movable relative to the beam and relative to the first section to support the legs of the patient in a plurality of positions.

First claim

The invention claimed is:

1. A patient support apparatus for spine surgery, the patient support apparatus comprising
a first lift column,
a second lift column spaced apart from the first lift column in a longitudinal dimension of the patient support apparatus,
a patient support frame extending longitudinally between the first and second lift columns, the patient support frame comprising a first section to support a torso of a patient, the first section having spaced apart first and second rails extending generally parallel with the longitudinal dimension of the patient support apparatus, the first section having a head end region coupled to the first lift column by a first coupling assembly, the patient support frame having a first beam that extends from the first section and that couples to the second lift column by a second coupling assembly, the first beam being coupled to a foot end region of the first section about midway between opposite sides of the first section,
a first set of leg support pads coupled to patient support frame and located on a first side of the first beam, the first set of leg support pads including a first thigh pad and a first ankle pad, and
a second set of leg support pads coupled to the patient support frame and located on a second side of the first beam, the second set of leg support pads including a second thigh pad and a second ankle pad.

2. The patient support apparatus of claim 1 , the patient support frame further comprising a second beam extending from the second coupling assembly in a cantilevered manner so as to terminate at a free end that is spaced from the first section of the patient support frame, the second beam being situated above the first beam, the first and second ankle pads being supported by the second beam on respective first and second sides thereof.

3. The patient support apparatus of claim 2 , wherein the first and second ankle pads extend laterally from respective first and second sides of the second beam and are each supported relative to the second beam in a cantilevered manner.

4. The patient support apparatus of claim 3 , wherein the second beam has first and second slots along the first and second sides and wherein the first and second ankle pads each have a respective support rod that extends into the respective first and second slot.

5. The patient support apparatus of claim 3 , wherein the first and second ankle pads are each independently adjustable along a length of the second beam.

6. The patient support apparatus of claim 2 , wherein, when the patient support frame is in a horizontal position supporting the patient in a prone position, the first beam comprises a first segment that angles downwardly with respect to the foot end region of the first section, a second segment that extends horizontally from a lower end of the first segment, and a third segment that angles upwardly from the second segment to the second coupling assembly.

7. The patient support apparatus of claim 6 , wherein the second coupling assembly includes an arced member that supports the foot end regions of the first and second beams, the patient support frame includes a first laterally extending member and a second laterally extending member coupled to the first laterally extending member for pivoting movement about an axis, the first segment of the first beam being coupled to the second laterally extending member, and the foot end regions of the first and second beams traveling along the arced member as the first and second beams pivot with the second laterally extending member about the axis.

8. The patient support apparatus of claim 7 , wherein the first and second laterally extending members serve as a hip support for the patient supported by the patient support frame in a prone position.

9. The patient support apparatus of claim 1 , further comprising first and second struts coupled to the first section, the first thigh pad and the first ankle pad being coupled to the first strut, the second thigh pad and the second ankle pad being coupled to the second strut, and wherein at least one of the first and second struts includes a first strut portion and a second strut portion that articulates at a joint relative to the first strut portion.

10. The patient support apparatus of claim 9 , wherein the first thigh pad is coupled to the first strut portion and the first ankle pad is coupled to the second strut portion.

11. The patient support apparatus of claim 10 , further comprising a knee pad coupled to the at least one of the first and second struts adjacent the joint.

12. The patient support apparatus of claim 1 , further comprising first and second struts coupled to the first section, the first thigh pad and the first ankle pad being coupled to the first strut, the second thigh pad and the second ankle pad being coupled to the second strut, and wherein at least one of the first and second struts includes a first strut portion and a second strut portion that telescopically extends and retracts relative to the first strut portion.

13. The patient support apparatus of claim 12 , wherein the first thigh pad is coupled to the first strut portion and the first ankle pad is coupled to the second strut portion.

14. The patient support apparatus of claim 13 , further comprising a knee pad coupled to the at least one of the first and second struts between the respective first and second thigh and first and second ankle pads.

15. The patient support apparatus of claim 1 , further comprising a set of torso supports coupled to one of the first and second rails, a pair of lateral supports coupled to the other of the first and second rails, each lateral support of the pair of lateral supports extending upwardly beyond upper surfaces of the torso supports when the patient is supported on the torso supports in a prone position, the lateral supports supporting a side of the patient's torso when the patient support frame is rotated with respect to the first and second lift columns to place the patient in a lateral position.

16. The patient support apparatus of claim 15 , wherein the pair of lateral supports each include a first support portion that couples to one of the first and second rails and a second support portion that adjustably moves toward and away from the first support portion to accommodate patients of different sizes.

17. The patient support apparatus of claim 16 , wherein each lateral support of the pair of lateral supports includes a bar that telescopically couples the second support portion to the first support portion.

18. The patient support apparatus of claim 16 , wherein the first support portion of each lateral support of the pair of lateral supports has a torso supporting surface and wherein the second support portion of each lateral support of the pair of lateral supports extends over the torso supporting surface when the lateral supports extend upwardly such that the first and second support portions are configured to cradle a side of the patient's torso.

19. The patient support apparatus of claim 9 , further comprising first and second collars that couple the first and second thigh pads, respectively, to the first and second struts, respectively, each of the first and second collars being movable along a length of the first and second struts, respectively.

20. The patient support apparatus of claim 19 , wherein the first and second collars are lockable to the first and second struts, respectively, to prevent movement of the first and second thigh pads relative to the first and second strut
