Embodiment Construction
[0021] In conjunction with the drawings, the present invention is further described in detail through examples, but the present invention is not limited to the following examples.
[0022] Such as figure 1 As shown: the automatic synovitis model-making special joint motion device described in this embodiment is mainly composed of a joint motion mechanism, a slide table, a positioning detection element and a control box.
[0023] The joint movement mechanism includes a thigh fixed plate 40 , a lower leg fixed plate 3 , a right-angled connecting rod 39 and a connecting rod 8 . Described thigh fixed plate 40 and calf fixed plate 3 are connected by thigh plate connecting shaft 2, thigh plate connecting bearing 1, thigh plate connecting bushing 42 and calf plate connecting bushing 43, and calf fixing plate can rotate around the axis. The specific connection method is: the upper and lower leg plate connecting bearings 1 are respectively fixed in the thigh plate connecting shaft sle...

An automatic joint movement device special for synovitis molding comprises a thigh fixing plate, a shank fixing plate, a connecting rod, a sliding table and two photoelectric sensors. The thigh fixing plate and the shank fixing plate are connected through a shaft and a bearing. The shank fixing plate and a sliding block on the sliding table are connected together through the connecting rod. The sliding table comprises a stepping motor, a toothed belt gear, a toothed belt, the sliding block, a guiding track, a base and the like. The two photoelectric sensors are fixed into fixing grooves in the side wall of the base of the sliding table and located at the two ends of the guiding track. When the joint movement device is in use, thighs and shanks of a rabbit are fixed to the thigh fixing plate and the shank fixing plate respectively; when device is operated, the shanks of the rabbit can automatically stretch and bend, and a deflection angle formed between the shank fixing plate and the thigh fixing plate is 10 degrees, so that the purpose of rapid traumatic synovitis molding is achieved.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and mainly relates to an automatic special joint mover for synovitis modeling. Specifically, it is an automatic special-purpose joint mobilizer for synovitis modeling, which can perform automatic stretching and flexion exercise on the knee joint of a rabbit, and the stretching and flexing angle and the stretching and flexing speed can be automatically adjusted. Background technique [0002] Traumatic synovitis of the knee joint is very common clinically, and its incidence rate reaches 2%-3%. At present, it is believed that the main reason is that the knee joint is overweight, the passive flexion and extension time is too long, or it is formed by the impact of external force. However, its etiology, pathogenesis, evolution and biological characteristics have not been fully understood. In order to carry out research on its etiology and preventive therapy, it is necessary to establish a mod...
