Abstract (en)

[origin: FR2763837A1] The invention concerns a device for compensating the amputation of a lower member by mechanical means, more particularly a leg prosthesis enabling a handicapped person to walk unassisted. The prosthesis comprises in its upper part an adjustable rod (2) fixed to a moulded sleeve (3) and in its lower part, an adjustable rod (4) fixed to an artificial foot (5). The knee axial articulation (6) consists of a female joint (10) and a male joint (12) made mutually integral by a through shaft (16). The shaft hole (19) is oblong and comprises a spring (20) maintained in its housing. The joints (10 & 12) being mutually integral by means of the shaft (16) passing through the oblong hole (19) enables the male joint (12) to move vertically inside the female joint (10). The invention is characterised in that it enables the person wearing the prosthesis to block the knee articulation (6) in vertical position when the weight of the body is resting on the prosthesis (1) an free axial rotation when the prosthesis (1) is released from the weight of the body which then rests on the other leg and alternately in a normal walking position.
