Sure-fit prosthetic attachment system

Abstract

An anchoring system for a transtibial or transfemoral (above or below the knee) prosthesis. The system includes a liner for enveloping an amputee limb. The liner has a buckle suspended toward the upper end, and a corresponding strap fixedly attached toward the bottom end of the liner. The anchoring system also includes a containment socket for seating the liner. The containment socket has a first slot there through at a position corresponding to the buckle of the liner. The socket also has a second slot there through at a position corresponding to the strap. In use, the patient first applies the liner, then inserts the liner into the socket with the fastening strap and buckle protruding out through the respective slots. The fastening strap is then threaded up through the buckle (the strap running upward along the side of the socket) and is inserted there through. The patient pulls down on the strap and it works by pulley action to draw the liner down into the socket until the liner is securely seated in the socket. When fully seated, the fastening strap is secured. The foregoing forms a suspension which holds the prosthesis on securely, and yet can easily be adjusted to reseat the limb.
