The lumbago is a common clinical disease, and according to statistics, more than 40 percent of people over 40 years old in China suffer from various lumbar diseases. Lumbar traction is a safe and effective treatment method. The ancient Chinese medical literature also has records of traction treatment of guiding stilt, swinging bones and muscles, moving branches and joints, and is a prototype of the development of modern traction therapy. The development of modern medicine, particularly the development of spine anatomy, physiology and biomechanics and the updating of traction equipment lays a theoretical foundation for the development and clinical application of modern traction technology.
The traction treatment is the most safe and effective one for treating the lumbar intervertebral disc protrusion, has very wide application and obvious treatment effect, and is practiced in a plurality of hospitals. The traction treatment is to apply a certain traction force to the pathological change part or the joint of a body by using an external force, so that the pathological change part and the joint are separated to a certain degree, and meanwhile, the surrounding soft tissues are pulled, thereby achieving the purpose of treatment. In recent years, the development of traction technology gradually develops from more original self-weight traction to form weight traction, mechanical traction, electric traction and intelligent traction. However, due to the limitation of the technical level, many famous local enterprises or research institutes in China, such as Shandong medical instrument research institute, Jiangsu De Feng medical equipment Co., Ltd, have more or less defects in manufacturing multifunctional intelligent traction treatment equipment, meanwhile, intelligent traction treatment equipment produced abroad occupies a large market proportion in China, and exceeds the homemade products in both manufacturing technology and patient experience, and the problem is that the price is too high, for example, the SDS non-operative spinal decompression retail price imported from the United states is more than 400 million RMB.
