Description

Technical Field

[0001] The invention relates to the field of scoliosis correction, in particular to a back chain type scoliosis adjusting brace. Background Art

[0002] Scoliosis is a three-dimensional deformity of the spine, including abnormal sequences in the coronal and sagittal planes. A normal person's spine should be a straight line when viewed from the back, and the trunk should be symmetrical on both sides. If the shoulders are not at the same height when viewed from the front or the back is uneven from the back, "scoliosis" should be suspected. At this time, a standing full spine X-ray should be taken. If the frontal X-ray shows that the spine has a lateral curvature of more than 10 degrees, it can be diagnosed as scoliosis. Severe scoliosis will affect the growth and development of infants, children and adolescents, causing body deformation. In severe cases, it can affect cardiopulmonary function and even involve the spinal cord, causing paralysis. Mild scoliosis can be observed and followed up, and patients with moderate scoliosis can try conservative treatment. If it develops into severe scoliosis, surgical treatment is required.

[0003] Brace treatment is the only internationally recognized and effective conservative treatment for scoliosis. However, the braces currently on the market are custom-made and can only be worn for one period. They cannot adapt to the changes in body shape during the growth of adolescents. There is also a problem that the design and production process rely on human experience, resulting in the brace not being able to fit the human physiological curvature well. Therefore, there is a need for a brace that can adjust the three-dimensional size and fit the human body better to achieve a better correction effect. Summary of the invention
