Abstract

Claims (45)

1. A universal arm assembly comprising:

a universal arm having a proximal end, a distal end, and a middle portion therebetween, the middle portion having a plurality of interconnected ball and socket pieces;

at least one clamp fixedly connected to the distal end of the universal arm by a connection joint, wherein the connection joint permits selective rotation of the at least one clamp by 360° with respect to the distal end of the universal arm;

a cable extending through each of the plurality of interconnected ball and socket pieces; and

a handle mechanism comprising:

at least one shaft connected to a linkage rod, the linkage rod connected to an end of the cable, wherein the at least one shaft is positioned substantially perpendicular to a length of the end of the cable, wherein a position of at least the end of the cable is movable relative to the at least one shaft based on a rotational movement of the at least one shaft;

a slotted rod, wherein the at least one shaft is inserted through a slot of the slotted rod;

a first bearing engaged with an exterior threaded portion of the at least one shaft, wherein the at least one shaft is inserted through the first bearing; and

a second bearing engaged with an exterior of the slotted rod, wherein the slotted rod is inserted through the second bearing;

wherein the linkage rod is physically coupled with the first bearing and the second bearing.

2. The universal arm assembly according to claim 1 , wherein the cable is moveable between a locked position and an adjustable position.

3. The universal arm assembly according to claim 2 , further comprising a rotatable handle connected to the at least one shaft.

4. The universal arm assembly according to claim 2 , wherein in the adjustable position the plurality of interconnected ball and socket pieces have a space between each ball and socket piece.

5. The universal arm assembly according to claim 3 , wherein in the locked position the plurality of interconnected ball and socket pieces have no space between each ball and socket piece.

6. The universal arm assembly according to claim 1 , wherein the at least one clamp includes a retractor ring holder and a second clamp.

7. The universal arm assembly according to claim 6 , wherein the second clamp is a spring-loaded clamp.

8. The universal arm assembly according to claim 1 , wherein the at least one shaft is connected to the end of the cable with at least one bearing threadedly engaged with the at least one shaft, at least one bearing connected to the end of the cable, and at least one linkage connected between bearings of the at least one bearing.

9. The universal arm assembly according to claim 8 , wherein the at least one linkage is pivotally connected between the bearings of the at least one bearing.

10. The universal arm assembly according to claim 1 , wherein the at least one shaft is connected to the end of the cable with at least two fixed bearings connected together with at least one linkage.

11. The universal arm assembly according to claim 1 , wherein the slotted rod is connected between the end of the cable and a threaded anchor.

12. The universal arm assembly according to claim 11 , wherein the slotted rod is connected to the threaded anchor with at least one threaded movable bearing.

13. The universal arm assembly according to claim 1 , wherein the connection joint permits selective rotation of the at least one clamp by 360° in at least two planes with respect to the distal end of the universal arm.

14. The universal arm assembly according to claim 1 , wherein the handle mechanism further comprises:

a third bearing engaged with the exterior threaded portion of the at least one shaft, wherein the at least one shaft is inserted through the third bearing; and

a second linkage rod physically coupled with the third bearing and the second bearing.

15. The universal arm assembly according to claim 14 , wherein the handle mechanism further comprises:

a fourth bearing engaged with an exterior threaded portion of the slotted rod, wherein the slotted rod is inserted through the fourth bearing;

a third linkage rod physically coupled with the fourth bearing and the third bearing; and

a fourth linkage rod physically coupled with the fourth bearing and the first bearing.

16. The universal arm assembly according to claim 15 , wherein:

at least one of the first bearing and the second bearing is fixed; and

at least one of the third bearing and the fourth bearing is movable.

17. The universal arm assembly according to claim 15 , wherein:

each of the first bearing and the second bearing is fixed; and

each of the third bearing and the fourth bearing is movable.

18. A universal arm assembly comprising:

a universal arm having a proximal end, a distal end, and a middle portion therebetween, the middle portion having a plurality of interconnected ball and socket pieces;

at least one clamp fixedly connected to the distal end of the universal arm by a connection joint;

a cable extending through each of the plurality of interconnected ball and socket pieces; and

a handle mechanism comprising:

at least one shaft connected to a linkage rod, the linkage rod connected to an end of the cable, wherein the at least one shaft is positioned substantially perpendicular to a length of the end of the cable, wherein a position of at least the end of the cable is movable relative to the at least one shaft based on a rotational movement of the at least one shaft;

a slotted rod, wherein the at least one shaft is inserted through a slot of the slotted rod;

a first bearing engaged with an exterior threaded portion of the at least one shaft, wherein the at least one shaft is inserted through the first bearing; and

a second bearing engaged with an exterior of the slotted rod, wherein the slotted rod is inserted through the second bearing;

wherein the linkage rod is physically coupled with the first bearing and the second bearing.
