Abstract:
1. An adjustable prosthesis system for a residual limb, comprising: an adjustable flexible outer shell having an adjustable inner volume and an adjustable inner shape, wherein the adjustable outer shell comprises a first flap having a first extended end, and a second flap opposite the first flap and having a second extended end, wherein at least a portion of the first flap overlaps at least a portion of the second flap so that at least a portion of the first extended end is on top of the second flap and at least a portion of the second extended end is under the first flap; at least one closure component attached to the adjustable flexible outer shell and adapted to adjust at least one of the adjustable inner volume and the adjustable inner shape of the adjustable flexible outer shell; an inner liner adapted to receive the residual limb and to be inserted in the adjustable inner volume of the adjustable flexible outer shell; and an adjustable connector having a proximal end adjustably connected to a distal end of the adjustable flexible outer shell and adapted to provide concurrently for a plurality of directional adjustments and/or angular adjustments of a position of the distal end of the adjustable flexible outer shell relative to the proximal end of the adjustable connector, a distal end of the adjustable connector being adapted to connect to a shank or an other prosthetic device, wherein the adjustable connector comprises an upper plate adapted to adjustably connect to the adjustable flexible outer shell, a lower plate below the upper plate and adapted to adjustably connect to the upper plate and to a shank or an other prosthetic device, and a plurality of rocker bolt assemblies adjustably connecting the lower plate to the upper plate, wherein at least a portion of a bottom surface of the upper plate is convex and at least a portion of an upper surface of the lower plate is concave and adapted to receive at least part of the convex portion of the bottom surface of the upper plate, wherein each rocker bolt assembly has a hollow threaded socket that extends downward through one of a plurality of apertures in the bottom surface of the upper plate and further downward through one of a plurality of adjacent corresponding apertures in the upper surface of the lower plate, the hollow threaded socket adapted to receive a threaded bolt, and wherein the directional adjustments are selected from a group consisting of a forward adjustment, a backward adjustment, a side-to-side adjustment, a rotational adjustment, and combinations thereof.
