PROSTHESIS

摘要

The invention relates to a prosthesis comprising two prosthesis parts (1, 3) connected for mutual movement which are characterized by actuable means (21) for locking respectively releasing the prosthesis parts (1, 3) relative to each other. The parts (1, 3) are preferably connected for mutual movement by means of an artificial joint (2) comprising a first (17) and a second (18) joint part. The locking means consist for instance of a tiltable locking element (21) under spring bias, a part of which co-acts in the locked position with a recess (27) in one of the joint parts (17), whereby tilting of the locking element (21) is bounded, and which in the released position is substantially freely tiltable. The prosthesis can be further provided with means (16) for actively placing the locking element (21) out of the active reach of the limiting recess (27). One (1) of the two prosthesis parts (1, 3) connected for mutual movement is formed by means for fixing the prosthesis to the remaining part of an amputated extremity (5), such as a cup (6) for receiving the outer end of the remaining part, means (9, 10, 11, 12) for fixing the prosthesis part (1) to a higher located part of the remaining part of the amputated extremity (5) and means for connecting the cup (6) and the fixing means (8). The second prosthesis part (3) is formed for instance by a device for replacing at least a part of the amputated extremtiy (5) and is preferably provided with damping means (49).
