ARTICULAR PROSTHESIS Russian patent published in 2007 - IPC A61F2/58 

FIELD: medicine, prostheses construction.

SUBSTANCE: the present innovation deals with prostheses of the upper limbs. Articular prosthesis contains an immobile case, a central axis, a mobile case, a roller coupling with a ring, a nave and rollers that rotate in opposite sides, 4 pushers supplied with foramens to interact with rollers' axes that rotate in one side and grooves to avoid interaction with rollers' axes that rotate in another side. The pushers are mutually connected and they are connected with corresponding axes of oppositely-rotating rollers, the length of which equals to the width of a nave and are located on a nave being toughly fixed upon an immobile case where lever-inducing control device is located. The control device is supplied with a pole with a spring-controlled pawl, and a cam of quadratic shape with a 8-teeth ratchet. A spring-controlled pawl-fixator is installed on an immobile case. A pole and a cam contact with each other due to interaction of a pole's pawl and a cam's ratchet that interacts with a lever. The ratchet interacts with a pawl-fixator. Both a cam and a pole are located on a central axis. Wrist and elbow pulls are introduced with corresponding small units. Elbow pull is toughly fixed upon a pole. Wrist one - with possibility for sliding along its small units. The innovation enables to widen functional possibilities of articular prosthesis, that is, its application in prostheses with active control.

EFFECT: higher efficiency of therapy.
