The footrest extension mechanism is advantaged in that adjusting flexibility of the footrest extension mechanism can be improved, and the extension length of the footrest extension mechanism can be increased.

A regulation-control orthosis for coronal plane deformity of an ankle is formed by a bone fixing support, steel needle fixing clamps connected onto the bone fixing support and steel needles clamped in the steel needle fixing clamps; the bone fixing support comprises a far end hole ring, a near end hole full ring arranged at the middle or middle upper section of a tibia, at least two fast extending lengthening rods connected between the far end hole ring and the near end hole full ring, a hole ring connecting rod provided with threads and connected between the far end hole ring and the near end hole full ring, and an arc hole ring adjustably connected to the hole ring connecting rod by an up-and-down adjusting nut and arranged at the middle lower section of the tibia. The regulation-control orthosis coronal plane deformity of the ankle is special for treating the strephexopodia or strephenopodia deformity of the ankle caused by synostosis, can perform traction, resetting, fixing and deformity correcting on fracture or deformity of the ankle in introversion and extroversion spaces, and is suitable for the traction, fixing and correcting on the coronal place of the ankle.

The invention discloses a long bone fracture repositioning device, which comprises a proximal end support frame, a distal end support frame, quick drawing extension rods, steel needle fixing clamps and steel needles, wherein the quick drawing extension rods are connected between the proximal end support frame and the distal end support frame, the steel needle fixing clamps are connected to the proximal end support frame and the distal end support frame, the steel needles are clamped by the steel needle fixing clamps, the proximal end support frame and the distal end support frame are same in structure and respectively comprise a transverse chute type repositioning slide plate and two fixed gliding hole plates which are connected to the chute type repositioning slide plate, one surface of each chute type repositioning slide plate is provided with a transverse guide sliding chute, a transverse guide long hole is formed between the bottom of the guide sliding chute and the other surface of the chute type repositioning slide plate, the fixed gliding hole plates are provided with holes for connecting the steel needle fixing clamps, the fixed gliding hole plates are further provided with positioning bulges which are matched with the guide sliding chutes and can slide along the guide sliding chutes. The long bone fracture repositioning device disclosed by the invention is simple in structure, the minimally invasive idea is enhanced, the excellent rate of repositioning is improved, and requirements of fracture repositioning and various malformation correcting can be met to the maximum extent.

The invention discloses a talipes equines orthosis. The talipes equines orthosis consists of a bone fixation support, a steel needle fixing clamp and a steel needle clamped in the steel needle fixing clamp, wherein the bone fixation support comprises a tibial hole full ring arranged on the middle segment or upper segment of a tibia, a calcaneal C-type hole ring arranged on the middle segment of a calcaneus, a metatarsal proximal C-type hole ring arranged at the promxial position of a metatarsus, and a metatarsal distal C-type hole ring arranged at the distal position of the metatarsus. The talipes equines orthosis solves the technical problem that traditional talipes equines orthoses used for correcting talipes equines have difficulty in meeting the orthosis and treatment needs of talipes equines. The talipes equines orthosis has the advantages that the operation is convenient and safe, the structure is simple and ingenious, an operation is guaranteed to be finished under the microinvasive or noninvasive condition, the damage to the local soft tissue injury and blood supply is avoided to the greatest extent, the fracture healing and function reconstruction are facilitated, the curative effect is high, and the complication is low.

The invention provides a belt (1) comprising a tension layer (4), a first end portion (2) at a first longitudinal end, a second end portion (3) at a second longitudinal end and a End connectors for joining the two end sections (2, 3). Here, the end connection comprises a first connection element (21) fastened to the first end part (2) and a second connection element (31) fastened to the second end part (3), wherein the first A connection element (21) and a second end connection piece (31) are detachably connected to each other and are made of stretch-resistant material. Each of the first connection element (21) and the second connection element (31) is integrally formed and together with the tension layer (4) forms a single neutral bending plane.

The invention provides a deep stretching anti-wrinkle and cracking-resistant process for ultra-thin plates and a mold thereof. The mold comprises an upper mold seat and a lower mold seat, wherein a lower supporting plate is arranged under the lower mold seat; an upper mold plate is arranged under the upper mold seat; three stretching punches are arranged under the upper mold plate; a lower mold plate is arranged on the lower mold seat; three stretching concave mold bodies are arranged in the lower mold plate; the stretching punches are matched with the stretching concave mold bodies in shape; the stretching concave mold bodies correspond to the stretching punches above in position; an inner demolding part is arranged in each stretching concave mold bodies; springs are arranged between the inner demolding parts and the lower supporting plate; and a pressing plate is arranged below the stretching punches and provided with edge pressing rings, and the edge pressing rings are located on the peripheries of the stretching punches. Materials to be stretched can flow into a forming mold cavity with sufficient size to be stretched so that the purpose of deep stretching of ultra-thin materials can be realized. The added edge pressing rings are used for shaping the roots of the stretched products, and the problem of wrinkling of the products is solved.
