The invention relates to a shoulder joint surgery and rehabilitation device which solves the problems that an existing shoulder arthroscopy surgery traction device is prone to causing displacement of a humerus head, operation is affected, and a postoperative fixing brace is prone to causing ankylosis of joints. Comprising an inflatable air bag, a first U-shaped arc and a second U-shaped arc are arranged on the two sides, opposite in direction, of the inflatable air bag respectively, an armpit supporting part is arranged between the first U-shaped arc and the second U-shaped arc, and the inflatable air bag is further provided with a wearing fixing piece, an inflation inlet and a pressure release valve. During use, the air bag is inflated through the inflation inlet, the first U-shaped arc is attached to the surface of a rib beside the armpit, the wearable fixing piece is used for wearing and fixing, the second U-shaped arc is used for containing the inner side of the upper arm, the armpit supporting part is used for supporting the armpit, the air bag forms a lever fulcrum at the armpit, the humeral head is pried to be away from the shoulder glenoid fossa, and the joint gap is increased; in addition, when the shoulder arthroscope is used after an operation, the joint capsule is relaxed, fixation is relatively relaxed, the range of activity after the operation is obviously enlarged, and early rehabilitation of a patient is facilitated.

The present invention discloses a multi-component synovitis therapeutic composition based on cartilage tissue repair and a use thereof, relating to the technical field of biomedicine. The composition comprises glucosamine hydrochloride, chondroitin sulfate, dimethyl sulfone, and graded molecular weight sodium hyaluronate. By compounding these components in precise parts by weight, the present invention constructs a gradient sustained-release and targeted delivery system for synovitis lesions. Dimethyl sulfone specifically inhibits hyaluronidase activity in the inflamed joint cavity, significantly reducing sodium hyaluronate degradation and prolonging the retention time of each active ingredient at the lesion site. High molecular weight sodium hyaluronate rapidly forms a lubricating protective film to achieve immediate analgesia and relieve ankylosis, while medium- and low-molecular-weight sodium hyaluronate penetrates the synovial barrier and carries cartilage repair components to the cartilage defect area, thereby achieving synergistic enhancement and comprehensively improving synovitis treatment efficacy.
