## Abstract

A limb support structure is disclosed. The limb support structure can include a one or more support structures, a locking swivel joint, and a gas pistol mounting element.

## Claims

### Claim 1

A limb support assembly comprising:
at least one limb holder support structure configured for coupling to a platform for supporting a subject's limb,
a locking swivel joint coupled to a proximal end of said limb holder support structure, the locking swivel joint being configured to maintain the limb holder support structure at a desired position relative to the platform; and
a gas piston assembly comprising:
a distal gas piston mounting element coupled to said limb holder support structure at a point distal relative to the locking swivel joint; and
a proximal gas piston mounting element connected to a limb holder support structure mounting element for coupling to the platform;
wherein at least one of the distal gas piston mounting element and the proximal gas piston mounting element is configured to be movable between at least two positions such that said distal gas piston mounting element moves relative to said at least one limb holder support structure and said proximal gas piston mounting element rotates relative to said limb holder support structure mounting element while the at least one limb holder support structure is moved through its range of motion.

### Claim 2 (depends on 1)

The limb support assembly of claim 1, wherein the platform comprises at least one of a patient bed, a surgical table, and a patient exam room table.

### Claim 3 (depends on 1)

The limb support assembly of claim 1, wherein the locking swivel joint is coupled to the platform via said limb holder support structure mounting element.

### Claim 4 (depends on 1)

The limb support assembly of claim 1, wherein said distal gas piston mounting element is axially movable relative to said at least one limb holder support structure.

### Claim 5 (depends on 1)

The limb support assembly of claim 1, wherein said proximal gas piston mounting element comprises a sleeve capable of sliding along a collar, wherein a proximal end of a gas piston of said gas piston assembly is coupled to the sleeve.

### Claim 6 (depends on 5)

The limb support assembly of claim 5, wherein said collar is fixedly attached to a distal portion of said limb support structure.

### Claim 7 (depends on 6)

The limb support assembly of claim 6, wherein said sleeve is axially movable along said collar.

### Claim 8 (depends on 7)

The limb support assembly of claim 7, wherein said collar comprises at least one slotted guide along which the sleeve can slide.

### Claim 9 (depends on 1)

The limb support assembly of claim 1, wherein both of said distal gas piston mounting element and said proximal gas piston mounting element are movable.
