ARTIFICIAL LOWER LIMB Russian patent published in 1994 - IPC

FIELD: medicine. SUBSTANCE: artificial limb consists of tubular forms which transform into sphere-shaped and bowl-shaped forms in point of their joints. Sphere-shaped form is inserted into bowl-shaped form and is sealed in place of weld. Bowl-shaped form terminates in close to tubular form and has a protraction which is inserted into cavity at the base of sphere-shaped form. Wall in the cavity is lower than from the front, this design permits to lift tubular form when bending. Moreover, all the forms in place of joint have holes for rope, which passes inside all the forms at specified tension. Forms are filled with lubricant liquid and have rollers to reduce friction of the rope against walls of the forms and when mating. Simultaneously, all the forms are fixed by tightening members from the front and from the back. The members are attached into slots of tubular form by bangles. In foot tubular forms are separated by geometrically connected flexible ring gaskets to make foot of artificial limb little mobility. EFFECT: improved efficiency. 7 dwg
