Abstract

Claims (20)

1 . An adjustable prosthetic socket, comprising:

a socket frame defining a central longitudinal axis, the socket defining a distal area and a proximal area at an opposite end of the socket relative to the distal area, the socket frame having:

a base at the distal area centered along the central longitudinal axis;

a first elongate component arranged along a first side of the socket frame extending from the base toward the proximal area while extending away from the central longitudinal axis;

and a second elongate component arranged along a second side of the socket frame extending from the base toward the proximal area while extending obliquely relative to the central longitudinal axis;

at least one cable extending through and spanning a clearance between the first and second elongate components, and a tensioning mechanism arranged to selectively tension the at least one cable to adjust a circumference of the socket frame between the first and second elongate components;

at least one textile sheet flexibly extending between the first and second elongate components; wherein the first and second elongate components include component includes at least two segments arranged along a length of the first and second elongate components, the at least two segments being pivotally connected to each other, and the at least one cable extends through the at least two segments along the length of the first and second elongate component, wherein the at least two segments of the first and second elongate components each define a plurality of channels for receiving the at least one cable, the plurality of channels are defined along an interior side of the at least two segments of the first and second elongate components

wherein the at least two segments are arranged to pivot inwardly and outwardly relative to the longitudinal axis.

2 . The adjustable prosthetic socket of claim 1 , wherein the at least one cable extends over the at least one textile sheet.

3 . The adjustable prosthetic socket of claim 1 , wherein the at least one textile sheet forms a sleeve extending about the circumference of the socket frame.

4 . The adjustable prosthetic socket of claim 1 , wherein the at least one textile sheet defines at least one pocket arranged to extend over at least one of the first and second elongate components.

5 . The adjustable prosthetic socket of claim 1 , further comprising a distal end piece received by the base and surrounded by the first and second elongated components, the distal end piece extending above the base along the central longitudinal axis.

6 . The adjustable prosthetic socket of claim 5 , wherein the distal end piece defines an interior contour arranged for receiving a distal end of a residuum and coextensive with at least a portion of the first and second elongate components.

7 . The adjustable prosthetic socket of claim 5 , wherein the distal end piece is arranged to receive a pin lock.

8 . The adjustable prosthetic socket of claim 1 , wherein the first elongate component is pivotally connected to the base.

9 . The adjustable prosthetic socket of claim 1 , wherein the first elongate component is rigidly connected to the base.

10 . The adjustable prosthetic socket of claim 1 , wherein the first elongate component includes a base segment connecting to a bent element secured to the base by extending radially from the base and bending to direct the first elongate component longitudinally from the base.

11 . The adjustable prosthetic socket of claim 10 , wherein at least one additional segment pivotally secures to the base segment and extends toward the proximal area, said at least one additional segment being pivotable relative to the central longitudinal axis.

12 . The adjustable prosthetic socket of claim 1 , wherein the at least two segments of the first and second elongate components are formed from metal.

13 . The adjustable prosthetic socket of claim 1 , wherein the at least two segments define a plurality of opposed apertures corresponding to opposed side walls, the plurality of opposed apertures of the at least two segments communicate with the plurality of channels and are arranged for the at least one cable to extend therethrough.
