Abstract

The invention relates to an active elbow joint rehabilitation machine, which includes a rotary pulling mechanism, a linear pulling mechanism and a human-machine interface mechanism; the linear pulling mechanism includes a sliding platform, a platform slide rail, a pull wire, a movable pulley, a fixed pulley, and a pull rod and a draw bar slot; the human-machine interface mechanism includes a forearm cuff and a forearm support; the platform slide rail is arranged on the bottom surface of the forearm support, and is matched and connected with the sliding platform, and the sliding platform can be placed on the The upper and lower surfaces of the sliding platform are respectively provided with the forearm cuff and the movable pulley; one end of the pull wire is fixed on the front part of the bottom surface of the forearm support, and the other end is bypassed The movable pulley then goes around the fixed pulley located on the bottom surface of the forearm support and is connected with the pull rod; the pull rod is arranged in the pull rod slot. The present invention does not cause secondary injury in the whole process of manual operation, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a rehabilitation machine device in the field of medical equipment, in particular to an active elbow joint rehabilitation machine. Background technique [0002] The elbow joint consists of the lower end of the humerus, the upper end of the ulna, and the upper end of the radius, and includes three joints, namely, the humerulnar joint, the humeroradial joint, and the proximal radioulnar joint. The physiological functions of the elbow joint are flexion, extension and rotation of the forearm. The normal range of elbow flexion and extension is between 0° and 140°. [0003] When the elbow joint is seriously injured, there are often symptoms of elbow flexion dysfunction after surgery, and postoperative rehabilitation often takes more than two months. The treatment of elbow flexion dysfunction is mainly through passive movement, joint traction, active movement, breaking through the limit angle, etc., to stretch the adherent scar tissu...
