Description

Fracture rehabilitation nursing fixing device of adjustable pressure Technical Field The invention relates to the technical field of orthopedic rehabilitation nursing instruments, in particular to a fracture rehabilitation nursing fixing device capable of adjusting pressure. Background Fracture is used as a clinically common bone injury type, and the fixation nursing in the rehabilitation stage is a key link for guaranteeing bone healing and avoiding secondary injury. Whether the lower limb diaphysis fracture, periarticular fracture or comminuted fracture, the fracture end is stably supported by the fixing device, abnormal activities are limited, and a good environment is provided for bone repair. Along with the progress of medical ideas, fracture rehabilitation is not limited to simple 'rigid fixation', but a mode of combining fixation and rehabilitation training is pursued, and the fixing device is required to ensure that a fracture end is stable, adapt to the bending and stretching training requirement of a patient, and simultaneously consider wearing comfort and pressure adjustability to adapt to the personalized requirements of different healing stages and different limb forms. The fracture fixing device commonly used in clinic at present mainly comprises a traditional plaster fixing device, a common support fixing device, an inflatable fixing device and the like. The traditional gypsum fixation has the defects of poor air permeability, large weight and incapability of adjusting pressure, is limited in limb movement of a patient after fixation, is unfavorable for early rehabilitation training, and can also cause skin injury, muscle atrophy and the like after detachment, the common support is fixed through a binding belt or a clamping plate, the normal support has certain air permeability and adjustability, the supporting force is mainly rigidly set, the dynamic adjustment cannot be carried out according to limb movement of the patient, the situation that the clamping is too tight to cause unsmooth blood circulation or the clamping is too loose to be fixed and fails easily occurs, the inflatable fixing device is inflated through the air bag to provide support, and can relieve local compression, but the air bag pressure adjustment precision is insufficient, and the cushioning protection design aiming at flexion and extension training is lacking, so that the fracture end stress abnormality is easily caused by sudden force unloading of the patient in rehabilitation exercise. The core pain points in the prior art are concentrated on three aspects, namely the stability and adjustability of supporting pressure are difficult to consider, most devices cannot realize accurate adjustment under constant supporting force, the capability of adapting to different rehabilitation stages is insufficient, a dynamic pressure adjusting mechanism adapting to limb bending and stretching actions is lacking, a fracture end is easily affected by abnormal stress in rehabilitation training, the fitting property and safety of a fixed structure are required to be improved, and partial devices have the problems of partial compression, poor ventilation or lack of secondary injury protection. These defects result in poor patient recovery experience and even affect fracture healing effects. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a fracture rehabilitation nursing fixing device with adjustable pressure, which solves the problems that the pressure of the traditional fracture fixing device cannot be accurately adjusted, the supporting force is unstable, the dynamic adaptation of flexion and extension training is not possible, and the secondary injury protection is lacking. The fracture rehabilitation nursing fixing device comprises a thigh fixing frame, wherein both sides of the tail end of the thigh fixing frame are movably provided with a shank fixing frame through a movable disc, both sides of the shank fixing frame are provided with a plurality of through holes, movable blocks are movably arranged in the through holes, transverse frames are fixedly arranged in the movable blocks, rotating frames are movably arranged on both sides of the transverse frames, spring plates are fixedly arranged on both sides of the inner portions of the transverse frames, the tail ends of the spring plates extend to the corresponding sides of the rotating frames, compression rollers are fixedly arranged at one ends of the inner side walls of the rotating frames, the tail ends of the compression rollers are abutted against the inner surfaces of the corresponding sides of the spring plates, one ends of the rotating frames close to the shank fixing frame are movably provided with connecting rods, the tail ends of the connecting rods are movably provided with compression rods, and the tail ends of the compression rods extend to the outer portions of the movable blocks and are fixedly arranged on both sides of the
