Abstract
A device configured to be positioned within a prosthetic socket includes a tether, a spool, a motor, a coupling mechanism, a release actuator, and a tightening actuator. A first end of the tether is configured to be coupled to a prosthetic liner, and a second end of the tether is coupled to the spool. The spool is fixed with respect to the prosthetic socket. The coupling mechanism transitions from a first position in which the spool is restricted to rotate in a first direction to a second position in which the spool is not restricted. The release actuator and tightening actuator are positioned on an exterior of the prosthetic socket. Actuating the release actuator causes the coupling mechanism to transition from the first position to the second position. Actuating the tightening actuator causes the motor to rotate the spool in the first direction to wind the tether around the spool.
