The utility model relates to a self-locking all elbow replacement artificial body, which involves an artificial false limb, specifically involves a full elbow replacement artificial body. The utility model comprises a humeral artificial body (1), an ulna artificial body (2) and a self-locking screw (11). The humeral artificial body (1) consists of a humeral artificial body stalk (3) and an elbow artificial body (4). The humeral artificial body stalk (3) is coaxial fixedly connected with the elbow artificial body (4). The ulna artificial body (2) consists of an ulna artificial body stalk (5) and an elbow joint artificial body (6). The artificial body stalk (5) is fixedly connected with the elbow joint artificial body (6); the elbow artificial body (4) and the elbow joint artificial body (6) have realized the moving connection through the screw (13). The humeral artificial body stalk (3) is opened a horizontal locking screw hole (9); the self-locking screw (11) connect with the horizontal locking screw hole (9) through thread. The utility model has easy operating installation; the horizontal self-locking nail is answering for the upper extremity biomechanical principle and the anti-rotation stress and the vertical pulling stress ability is strong; after operation, the artificial body loosening and removal rate has greatly reduced.
