Abstract

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

First claim

The invention claimed is:

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 system 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 adjustable prosthetic socket extending from the base toward the proximal area while extending obliquely relative to the central longitudinal axis;

at least one cable connecting to the first and second elongate components, and a tensioning mechanism arranged to that selectively tension the at least one cable to adjust a circumference of the socket frame between the first and second elongate components;
wherein the first and second elongate components each define a plurality of channels for receiving the at least one cable;
wherein the first elongate component includes at least first and second lateral flaps extending generally perpendicularly relative to the central longitudinal axis, the second lateral flap located adjacently above the first lateral flap along a length of the first elongate component, the first and second lateral flaps each having an arcuate shape extending about the central longitudinal axis and define the plurality of channels at opposed end portions thereof.

2. The adjustable prosthetic socket of claim 1 , wherein the first elongate component includes at least two segments arranged along a length of the first elongate component, the at least two segments being pivotally connected to each other.

3. The adjustable prosthetic socket of claim 1 , further comprising a distal end piece received by the base and surrounded by the first and second elongate components.

4. The adjustable prosthetic socket of claim 3 , wherein the distal end piece defines an interior contour arranged for receiving a distal end of a residuum.

5. The adjustable prosthetic socket of claim 3 , wherein the distal end piece is arranged to receive a pin lock.

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

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

8. 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 and directing the first elongate component longitudinally from the base.

9. The adjustable prosthetic socket of claim 8 , 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.

10. The adjustable prosthetic socket of claim 1 , wherein the first and second elongate components each include at least two segments pivotally connected to one another, said at least two segments are arranged to adapt to a shape of a residuum.

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

12. The adjustable prosthetic socket of claim 1 , wherein the first elongate component defines a plurality of apertures communicating with the plurality of channels and arranged for the at least one cable to extend therethrough.

13. 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 adjustable prosthetic socket 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 system extending from the base toward the proximal area while extending obliquely relative to the central longitudinal axis;

at least one cable connecting to the first and second elongate components, and a tensioning mechanism arranged to that selectively tension the at least one cable to adjust a circumference of the socket frame between the first and second elongate components;
wherein the first and second elongate components each define a plurality of channels for receiving the at least one cable;
wherein the first elongate component includes a base segment connecting to a bent element secured to the base and directing the first elongate component longitudinally from the base;
wherein the first elongate component includes at least first and second segments pivotally connected to one another, the first segment connecting to the base segment, the first and second segments are arranged to pivotally adapt to a shape of a residuum;
wherein the first elongate component includes at least first and second lateral flaps extending generally perpendicularly relative to the central longitudinal axis, the second lateral flap located adjacently above the first lateral flap along a length of the first elongate component, the first and second lateral flaps each having an arcuate shape extending about the central longitudinal axis and define the plurality of channels at opposed end portions thereof.

14. The adjustable prosthetic socket of claim 13 , wherein the first and second elongate components are formed from metal.

15. The adjustable prosthetic socket of claim 13 , further comprising a distal end piece received by the base and surrounded by the first and second elongate components.

16. The adjustable prosthetic socket of claim 15 , wherein the distal end piece defines an interior contour arranged for receiving a distal end of a residuum.

17. The adjustable prosthetic socket of claim 15 , wherein the distal end piece is arranged to receive a pin lock.

18. The adjustable prosthetic socket of claim 15 , wherein distal end piece defines a recess formed along the central longitudinal axis and configured and dimensioned to receive a pin from a prosthetic liner.

19. 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 system 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 system extending from the base toward the proximal area while extending obliquely relative to the central longitudinal axis;

at least one cable connecting to the first and second elongate components, and a tensioning mechanism arranged to that selectively tension the at least one cable to adjust a circumference of the socket frame between the first and second elongate components;
a distal end piece received by the base and surrounded by the first and second elongate components, the distal end piece defining an interior contour arranged for receiving a distal end of a residuum;
