ABSTRACT:
An anchoring system for a transtibial or transfemoral (above or below the knee) prosthesis. The anchoring system includes a liner for enveloping an amputee limb. The liner has a first strap releasably secured to the fabric of the liner by a reinforcement plate that has a particular molded hook backing that removably adheres to the liner in such a way as to still provide a secure anchor for the buckle. The liner also has a second strap fixedly attached to the distal bottom end of the liner. The anchoring system also includes a containment socket for seating the liner. The containment socket has a pair of slots there through at positions corresponding to the two straps of the liner, respectively. To apply the anchoring system, the patient first applies the liner to his/her limb. The liner is then inserted into the socket with the two fastening straps protruding out through the respective slots. The patient pulls down on the lower strap thereby drawing the liner down into the socket until the liner is securely seated in the socket. When fully seated, the two fastening straps are overlayed and secured to themselves by Velcro® or the lower strap is threaded through a buckle on the upper strap and secured onto itself with Velcro®. The foregoing forms a suspension which holds the prosthesis on. Moreover, the fastening straps through slots absolutely prevent lateral shift as well as rotation.
