Orthopedic traction training device for postoperative rehabilitation

Abstract

The invention discloses an orthopedic traction training device for postoperative rehabilitation, which relates to the technical field of medical instruments and comprises a rehabilitation training module, a traction module and the like. The traction module adopts a differential screw mechanism, so that a continuous and uniform stress application traction effect can be realized; a hook in the traction module is matched with a multi-line thread pair through clutch type internal and external splines, so that the function of quickly unloading force can be realized; the rehabilitation training module can support the legs of the patient, and the angle change range is 0-60 degrees; a second spring is arranged in the regulation and control assembly, and the patient can lift the legs by overcoming the elastic force of the second spring for rehabilitation exercise; the initial tension of the second spring can be adjusted along with the rehabilitation process of the patient, so that the optimal rehabilitation training effect is achieved; the rehabilitation training module is detachably provided with a short flat plate and a long flat plate, and has an anti-overturning effect; the section of the short flat plate is rectangular or sector-ring-shaped, when the section is sector-ring-shaped, two rehabilitation training modules can be connected, and the rehabilitation training device is suitable for the situation of two-leg fracture.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic traction training device for postoperative rehabilitation. Background technique [0002] Traction is the use of the principle of action force and reaction force in mechanics to act on the affected limb through the pull of gravity to relieve the tension and retraction of the soft tissue at the fracture or dislocation, so as to reset the fracture or dislocation and achieve the purpose of treatment. Taking leg fractures as an example, in the existing clinical practice, simple traction techniques are often used, that is, weights are suspended by a set of ropes, and the affected area is pulled by gravity. This method is not conducive to the movement of the patient's legs, and the weight of the weights For a fixed value, the weight can only be increased or decreased piece by piece, and the effect of continuous and uniform force application cannot be achieved. In ...

Taking leg fractures as an example, in the existing clinical practice, simple traction techniques are often used, that is, weights are suspended by a set of ropes, and the affected area is pulled by gravity. This method is not conducive to the movement of the patient's legs, and the weight of the weights For a fixed value, the weight can only be increased or decreased one by one, and the effect of continuous and uniform force cannot be achieved

In this regard, for example, the patent No. 201910547421.9 proposes a movable orthopedic traction frame. This device can be classified as a seat that realizes the traction function. It is driven by hydraulic pressure to realize the traction function. Its advantages are perfect functions, It can improve the work efficiency of medical staff; the disadvantage is obvious, hydraulic drive, there is a problem of hydraulic oil pollution, which also makes the whole system complex, and the cost of manufacturing and maintenance increases. Secondly, the most important thing is that the device cannot be used with the hospital bed and needs The patient is transferred from the hospital bed to the device, but patients with fractures often need to rest and cannot change the bedding frequently. From a practical point of view, the device is not very practical
