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, a port, and first and second guide paths extending through a wall of the receptacle;
a panel disposed within the port of the receptacle and configured to move relative to the port, the panel comprising first and second guide paths extending through a wall of the panel from a first end of the panel to a second end of the panel, the first end being opposite the second end;
a tensioning line extending through one or more of the first and second guide paths of the receptacle and through one or more of the first and second guide paths of the panel; and
a tightening member coupled to the tensioning line, wherein the tightening member is configured to increase or decrease tension in the tensioning line, wherein increasing tension in the tensioning line moves the panel radially inward.
2. The adjustable prosthetic socket of claim 1 , further comprising a second panel disposed within a second port of the receptacle, the second panel comprising a guide path extending through a wall of the second panel.
3. The adjustable prosthetic socket of claim 2 , wherein the tensioning line extends through the guide path of the second panel such that increasing tension in the tensioning line moves the second panel radially inward.
4. The adjustable prosthetic socket of claim 2 , further comprising a second tensioning line extending through a third guide path of the receptacle and through the guide path of the second panel; and
a second tightening member coupled to the second tensioning line, wherein the second tightening member is configured to increase or decrease tension in the second tensioning line, wherein increasing tension in the second tensioning line moves the second panel radially inward.
5. The adjustable prosthetic socket of claim 1 , wherein the panel extends longitudinally along a longitudinal length of the receptacle.
6. The adjustable prosthetic socket of claim 1 , wherein the receptacle comprises one or more laminated layers.
7. The adjustable prosthetic socket of claim 1 , wherein the receptacle comprises one or more plastic resins.
8. The adjustable prosthetic socket of claim 1 , wherein the tightening member comprises an actuator coupled to a spool, wherein actuation of the actuator effects rotation of the spool to wind or unwind the tensioning line about the spool to increase or decrease tension in the tensioning line.
9. The adjustable prosthetic socket of claim 1 , wherein the tightening member comprises a motor to effect tightening or loosening of the tensioning line.
10. The adjustable prosthetic socket of claim 1 , wherein the first and second guide paths of the panel are substantially parallel with one another.
11. An adjustable prosthetic socket, comprising:
a receptacle comprising a cavity, one or more ports, and first and second guide paths extending through a wall of the receptacle;
a first panel and a second panel, each panel disposed within a port of the receptacle and configured to move relative to the port, each panel comprising first and second guide paths extending through a wall of the panel from a first end of the panel to a second end of the panel, the first end being opposite the second end;
a tensioning line extending through one or more of the first and second guide paths of the receptacle and through one or more of the first and second guide paths of the first panel; and
a tightening member coupled to the tensioning line, wherein the tightening member is configured to increase or decrease tension in the tensioning line, wherein increasing tension in the tensioning line moves the first panel radially inward.
12. The adjustable prosthetic socket of claim 11 , wherein the receptacle comprises a first port and a second port, wherein the first panel is disposed within the first port, and wherein the second panel is disposed within the second port.
13. The adjustable prosthetic socket of claim 11 , wherein the tensioning line further extends through one or more of the first and second guide paths of the second panel.
14. The adjustable prosthetic socket of claim 11 , further comprising:
a second tensioning line extending through one or more of third and fourth guide paths of the receptacle and through one or more of the first and second guide paths of the second panel; and
a second tightening member coupled to the second tensioning line, wherein the second tightening member is configured to increase or decrease tension in the second tensioning line, wherein increasing tension in the second tensioning line moves the second panel radially inward.
15. The adjustable prosthetic socket of claim 11 , wherein the first panel and second panel each extend longitudinally along a longitudinal length of the receptacle.
16. The adjustable prosthetic socket of claim 11 , wherein the receptacle comprises one or more laminated layers.
17. The adjustable prosthetic socket of claim 11 , wherein the receptacle comprises one or more plastic resins.
18. The adjustable prosthetic socket of claim 11 , wherein the tightening member comprises an actuator coupled to a spool, wherein actuation of the actuator effects rotation of the spool to wind or unwind the tensioning line about the spool to increase or decrease tension in the tensioning line.
19. The adjustable prosthetic socket of claim 18 , wherein the tightening member comprises a motor to effect tightening or loosening of the tensioning line.
20. The adjustable prosthetic socket of claim 11 , wherein the first and second guide paths of the first panel are substantially parallel with one another.
