Background

Scoliosis, which is a spinal deformity in which one or several segments of the spine are bent laterally with rotation of the vertebral body and an increase or decrease in kyphosis or lordosis in the sagittal plane, is a three-dimensional deformity defined by the international scoliosis institute as follows: the scoliosis is called as scoliosis by measuring the spinal curvature of the standing spinal orthostatic X-ray film by using a Cobb method and measuring the angle of the spinal orthostatic X-ray film to be more than 10 degrees.

When the spine is bent in one or more sides, the spine can be gradually aggravated, so that the functions of the heart and the lung of a patient can be affected by the spine, the thorax, the rib, the pelvis and a serious patient, even the spinal cord is affected, and paraplegia is caused.

The existing spinal halo gravity traction technology mainly comprises bed traction and wheelchair traction, wherein the patient needs to be continuously bedridden under the former condition, and the patient can keep a certain degree of freedom of life while being dragged by the latter. The existing wheelchair traction technology has the following problems:
