摘要

The fixing comorises a mounting block (1) flanked by a pair of parallel flanges (2,3). A pulley (6) is rotatably mounted between the upper ends of the flanges with a space (8) between the pulley and the block for the passage of the tapes securing sock or sleeve to the stump. The block is supported at its lower end by a stirrup (9) which has a threaded lower tip (12). The tip is screwed onto the end of a series of vertical supporting rods which run up the side of the prosthesis and are connected at the lower end to a stirrup into which the prosthetic foot fits.
