[0002] Traction is a common physical rehabilitation method in the medical field. It mainly applies the principle of action and reaction in mechanics. Through special instruments or electric traction devices, a pulling force is applied to a certain part of the body or joint, so that the joint surface is separated to a certain extent and the surrounding soft tissue is properly stretched. The main purpose of this treatment method is to achieve the effects of reduction, fixation, relieving nerve root compression, and correcting joint deformities.
[0003] Especially when treating shoulder disc herniation, a traction bed is generally used. The traction bed includes a bed body, a movable pad, a fixed pad and a hand-driven mechanism. The fixed pad is located in the front of the bed body and is fixedly matched with the bed body, and the movable pad is located behind the bed body and is movably matched with the bed body. The patient's torso lies on the fixed pad and is fixed by straps, and the legs and buttocks lie on the movable pad and are fixed by straps. The hand-driven mechanism is operated by medical staff to make the movable pad close to or away from the fixed pad, thereby performing traction rehabilitation.
[0004] However, the above-mentioned traction bed has the following problems: ① The trunk and legs are fixed with straps. In order to ensure the fixation effect, the straps are too tight, which causes discomfort to the patient; ② The hand-driven mechanism requires continuous operation by medical staff, which will cause a certain burden to the medical staff. At the same time, the traction rehabilitation effect is related to the traction force, and different patients require different traction forces. Due to the limitations of manual operation and the different operating experience of different medical staff, the traction force changes all the time, which affects the rehabilitation effect.
