Abstract

A stabilizing pad configured for positioning on a surgical table onto which a patient is placed for a surgical procedure, the stabilizing pad comprising: a high friction top surface; and a high friction bottom surface; wherein the stabilizing pad comprises foam.

First claim

What is claimed is:

1. A table extender, the table extender comprising:
a base configured for extending beneath hips of a patient, the base comprising:
a proximal portion for positioning adjacent to a surgical table,
a distal portion disposed opposite the proximal portion and comprising one or more openings for optional mounting of a perineal post, and
an intermediate portion disposed between the proximal portion and the distal portion,

wherein the base of the table extender is radiolucent;
a cushion mounted to the base; and
mounts configured for user releasable mounting of the base to side rails of a surgical table so that the base can support the hips of the patient, the side rails extending longitudinally along and being spaced from sides of a platform of the surgical table, wherein the mounts comprise slotted clamps configured to slide longitudinally along the side rails when mounting, and the mounts are configured to mount the table extender in only one orientation with respect to the surgical table in which a top surface of the cushion is aligned with a top surface of the surgical table that contacts the patient,
wherein the base and cushion have a rectangular shape so that the hips of the patient can be positioned entirely on the top surface of the cushion.

2. The table extender of claim 1 , wherein the table extender comprises at least one marking for indicating the desired position of the hip joints of a patient on the table extender.

3. The table extender of claim 1 , wherein the table extender is approximately the length of a human femur.

4. The table extender of claim 1 , wherein the table extender is configured to enable a lateral X-ray of a patient's hip without image obstruction.

5. The table extender of claim 1 , further comprising a leg support mounted to the distal portion of the table extender.

6. The table extender of claim 5 , wherein the leg support is detachable from the table extender.

7. The table extender of claim 5 , wherein the leg support is extendable and retractable relative to the table extender.

8. The table extender of claim 5 , wherein the leg support is pivotally mounted to the distal portion of the table extender.

9. The table extender of claim 1 , wherein the table extender comprises at least one inclinometer for indicating the angular disposition of the table extender and the surgical table relative to a floor.

10. The table extender of claim 9 , wherein the at least one inclinometer is mounted on at least one of the mounts.

11. The table extender of claim 1 , wherein the table extender is sized to support a patient from a point proximal to the hips of the patient to a point proximal to the knees of the patient.

12. The table extender of claim 10 , wherein the at least one inclinometer is attached to the proximal portion of the table extender.

13. The table extender of claim 1 , wherein the table extender is sized so that when a patient is disposed on the table extender, the hip joint of the patient will be positioned proximal to the distal portion of the table extender.

14. The table extender of claim 1 , wherein the distal portion of the table extender and the intermediate portion of the table extender are substantially radiolucent.

15. The table extender of claim 1 , wherein greater than approximately 80% of the surface area of the table extender is radiolucent.

16. The table extender of claim 1 , wherein the table extender comprises at least one or more openings.

17. The table extender of claim 16 , wherein the at least one more openings comprise side openings for enabling easy grasping of the table extender and/or for receiving straps of a stabilizing pad.

18. The table extender of claim 16 , wherein the at least one more openings comprise a distal opening for enabling other equipment to be mounted to the table extender.

19. The table extender of claim 1 , wherein the slotted clamps comprise hand screws that are configured for grasping by hand for hand tightening the hand screws for locking the mounts to the side rails.

20. The table extender of claim 1 , wherein at least a portion of each slotted clamp slides between a respective side rail and the platform of the surgical table when the slotted clamps are slid onto the side rails.

21. The table extender of claim 1 , wherein the cushion comprises at least one recess for accommodating the optional mounting of the perineal post.

22. The table extender of claim 1 , comprising a perineal post configured for optional mounting to the one or more openings of the distal portion.

23. The table extender of claim 1 , wherein there is no metal reinforcement extending across a width of the table extender.
