Adjustable prosthetic interfaces and related systems and methods
Prosthesis devices can include sockets having adjustable features. In one example, a socket includes one or more panels that can move outwardly or inwardly relative to a receptacle portion of the socket. The panels can be moved by tightening a tensioning line.
1. An adjustable prosthetic socket, comprising:
a receptacle comprising a cavity that is sized to receive at least a portion of a residual limb therein;
a panel, wherein the panel is configured to move radially inward relative to the cavity, wherein the panel is coupled to the receptacle via a hinge; and
an adjustment mechanism configured to selectively fix the panel at a desired position relative to the cavity.
2. The adjustable prosthetic socket of claim 1 , further comprising a tensioning line that is coupled with the panel, wherein the adjustment mechanism is coupled with the tensioning line and is configured to move the tensioning line so as to effect movement of the panel to the desired position.
3. The adjustable prosthetic socket of claim 1 , wherein the panel comprises a pad at an interior surface thereof such that the panel is thicker than a wall portion of the receptacle.
4. The adjustable prosthetic socket of claim 1 , wherein the adjustment mechanism is configured to lock the panel at the desired position relative to the cavity.
5. The adjustable prosthetic socket of claim 1 , wherein the panel is configured to move to the desired position without changing a configuration of the receptacle of the adjustable prosthetic socket.
6. An adjustable prosthetic socket, comprising:
a receptacle comprising a cavity that is sized to receive at least a portion of a residual limb therein;
a pressure member that is separate from the receptacle and that is configured to move relative thereto, wherein the pressure member is coupled to the receptacle via a hinge; and
an adjustment mechanism configured to selectively fix the pressure member at a desired position relative to the cavity;
wherein movement of the pressure member toward an interior of the cavity is configured to tighten a fit between the adjustable prosthetic socket and at least a portion of a residual limb.
7. The adjustable prosthetic socket of claim 6 , wherein the pressure member comprises a pad at an interior surface thereof such that the pressure member is thicker than a wall portion of the receptacle.
8. The adjustable prosthetic socket of claim 6 , wherein the adjustment mechanism is configured to lock the pressure member at the desired position relative to the cavity.
9. The adjustable prosthetic socket of claim 6 , wherein the pressure member is configured to move to the desired position without changing a configuration of the receptacle of the adjustable prosthetic socket.
10. An adjustable prosthetic socket, comprising:
a receptacle comprising a cavity that is sized to receive at least a portion of a residual limb therein;
a pressure member that is separate from the receptacle and that is configured to move relative thereto, wherein the pressure member comprises a pad at an interior surface thereof such that the pressure member is thicker than a wall portion of the receptacle; and
an adjustment mechanism configured to selectively fix the pressure member at a desired position relative to the cavity;
wherein movement of the pressure member toward an interior of the cavity is configured to tighten a fit between the adjustable prosthetic socket and at least a portion of a residual limb.
11. The adjustable prosthetic socket of claim 10 , wherein the pressure member is free floating relative to the receptacle portion of the socket.
12. The adjustable prosthetic socket of claim 10 , wherein the pressure member is coupled to the receptacle via a hinge.
13. The adjustable prosthetic socket of claim 10 , wherein the adjustment mechanism is configured to lock the pressure member at the desired position relative to the cavity.
14. The adjustable prosthetic socket of claim 10 , wherein the pressure member is configured to move to the desired position without changing a configuration of the receptacle of the adjustable prosthetic socket.
15. The adjustable prosthetic socket of claim 10 , further comprising a tensioning line that is coupled with the pressure member, wherein the adjustment mechanism is coupled with the tensioning line and is configured to move the tensioning line so as to effect movement of the pressure member to the desired position.
16. The adjustable prosthetic socket of claim 10 , comprising a plurality of pressure members.
17. The adjustable prosthetic socket of claim 10 , wherein the adjustment mechanism comprises a ratcheting device.
18. The adjustable prosthetic socket of claim 6 , further comprising a tensioning line that is coupled with the pressure member, wherein the adjustment mechanism is coupled with the tensioning line and is configured to move the tensioning line so as to effect movement of the pressure member to the desired position.
19. The adjustable prosthetic socket of claim 6 , comprising a plurality of pressure members.
20. The adjustable prosthetic socket of claim 1 , comprising a plurality of panels.
