Abstract
A system and method for releasably securing a prosthetic limb to a residual limb. The system and method utilizes a lanyard for drawing the residual limb into a receiving portion of the prosthetic limb and for helping to maintain attachment of the prosthetic limb to the residual limb. The lanyard is routed through a releasable ratchet mechanism, which allows tension to be incrementally applied to the lanyard and further prevents the lanyard and the residual limb connected thereto from moving in an opposite direction. A suction cup may also be employed within the receiving portion of the prosthetic limb for aiding in retention of the residual limb. The ratchet mechanism allows the system to be used without maintaining constant tension on the lanyard, thereby reducing the amount of effort required of the user. The system and method also reduces or even eliminates pistoning of the residual limb within the prosthetic limb during movement of the user.
