DYNAMIC STRUCTURE FOR ORTHOPAEDIC PROSTHESIS FOR THE LOWER LIMBS

摘要

The vertical tube 6, descending from the tapering of the stump, is pivoted transversally at 7 at the end of the cylinder 8 of a double-acting spring shock absorber and constrained to the heel part of the sole 1A-1B by means of a spherical joint formed by the spherical head 10 of the rod 9 and by the support 13 pivoted, in the bosses 14 of the two laminas 1A and 1B, along two axes parallel to the longitudinal centreline of the sole. The tube 6 is also fixed to the curved and flexible laminas 2 and 3 of which the first is partially sheared to form two arms 2A and 2B fixed separately to the corresponding laminas 1A and 1B of the sole while the lamina 3 on the other hand extends towards the front of the foot to rest, with a sliding piece 4 adjustable by screw, on a multilayer element 5 placed astride the laminas 1A and 1B.
