Abstract

A sterile hand connection device is used to attach a patient's arm to a cable adaptor of a surgical arm positioning apparatus. The cable adaptor is connected to two cable ends of a cable of the surgical arm positioning apparatus. The hand connection includes a clip, a buckle, and a wrap that is mounted to the clip. The buckle is attached to the cable adaptor and the clip snaps onto the buckle. The hand wrap is mounted to the clip and wraps around a patient's hand, wrist, and forearm.

First claim

The invention claimed is:

1. A hand connection device for attaching a patient's arm to a connection member that is coupled to opposite ends of a looped cable of a surgical arm positioning system, the hand connection device comprising:
a buckle supported with respect to the connection member, the buckle including an elongated arm member having a snap feature receiving hole provided at a central region thereof and two outwardly facing wide feature receiving cavities that are open at opposite outer ends of the elongated arm member and that are open at a bottom surface of the elongated arm such that the snap feature receiving hole and the two outwardly facing wide feature receiving cavities are each open and spaced apart from each other at the bottom surface of the elongated arm member,
a clip defined by a generally U-shaped body having a pair of substantially parallel spaced apart arms and the connection member interconnecting the arms, the clip having a snap feature extending from a middle region of the connection member, the snap feature being configured to snap into the snap feature receiving hole of the buckle, the clip further having a pair of wide features with each wide feature of the pair of wide features extending from a respective opposite end of the connection member in generally parallel relation with the snap feature, the wide features being configured for receipt in the two outwardly facing wide feature receiving cavities of the buckle, and
a hand wrap for attaching the patient's arm to the clip, the hand wrap comprising a foldable sheet and being configured to wrap around the patient's hand and wrist, the hand wrap having a perforation through which the snap feature is inserted when the hand wrap is attached to the clip, the hand wrap being folded around the connection member of the clip such that portions of the hand wrap are situated between the snap feature and each wide feature of the pair of wide features of the clip.

2. The hand connection device of claim 1 , wherein the pair of substantially parallel spaced apart arms extend from the connection member in a first direction and the snap feature and pair of wide features extend from the connection member in a second direction opposite to the first direction.

3. The hand connection device of claim 1 , wherein the hand wrap comprises a foam material.

4. The hand connection device of claim 1 , wherein the foldable sheet of the hand wrap comprises a wrist portion having at least one wrist strap for wrapping around the patient's wrist.

5. The hand connection device of claim 4 , wherein the at least one wrist strap has a wrist strap fastener.

6. The hand connection device of claim 5 , wherein the wrist strap fastener comprises a hook material and the foldable sheet comprises a loop material.

7. The hand connection device of claim 1 , wherein the hand wrap further includes a forearm portion having at least one forearm strap configured to wrap around the patient's forearm.

8. The hand connection device of claim 7 , wherein the at least one forearm strap has a forearm strap fastener.

9. The hand connection device of claim 8 , wherein the forearm strap fastener comprises a hook material and the foldable sheet comprises a loop material.

10. The hand connection device of claim 1 , wherein the hand wrap further includes two wide feature receiving indentations and wherein the pair of wide features are received by the wide feature receiving indentations when the hand wrap is coupled to the clip.

11. The hand connection device of claim 1 , wherein the hand wrap is configured to be sterilized by ultraviolet irradiation.

12. The hand connection device of claim 1 , further comprising a clip adaptor coupled to the buckle, the clip adaptor being situated between the buckle and the connection member.

13. The hand connection device of claim 12 , further comprising a flange situated between the connection member and the clip adaptor.

14. The hand connection device of claim 1 , wherein a hand receiving gap is defined between the substantially parallel spaced apart arms of the clip, and wherein the hand receiving gap is configured to receive at least a portion of the patient's hand when the patient's arm is attached to the clip by the hand wrap.

15. The hand connection device of claim 1 , wherein the hand wrap includes flaps that are wrapped around respective arms of the clip to form a respective loop when the hand wrap is attached to the clip.

16. The hand connection device of claim 15 , wherein each respective loop is closed around the respective arm by attaching the corresponding flap to itself.

17. The hand connection device of claim 16 , wherein the flaps are sewn to themselves to form the respective loops with each loop having an arm receiving opening.

18. The hand connection device of claim 1 , further comprising a clip adaptor and a hook extending from the clip adaptor, the clip adaptor being coupled to the buckle, and the hook being configured to attach the clip adaptor to the connection member.

19. The hand connection device of claim 18 , wherein the hook is spring loaded.

20. The hand connection device of claim 19 , further comprising a knob that rotates relative to the clip adaptor to move the hook relative to the clip adaptor.

21. The hand connection device of claim 1 , further comprising a clip adaptor, the clip adaptor being cylindrically shaped and having a notch in which a portion of the buckle is received.

22. The hand connection device of claim 21 , wherein the buckle is generally perpendicular to the clip adaptor with portions of the buckle extending in opposite directions from the clip adaptor.
