Description

Lumbar vertebra shoulder disc protrusion correcting device

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a lumbar disc herniation correction device.

Background

The lumbar intervertebral disc protrusion is one of the more common diseases, mainly because each part of the lumbar intervertebral disc (nucleus pulposus, annulus fibrosus and cartilage plates), especially the nucleus pulposus, has degenerative changes of different degrees, under the action of external force factors, the annulus fibrosus of the intervertebral disc is ruptured, and nucleus pulposus tissues protrude (or are separated) from the ruptured part to the back or the vertebral canal, so that adjacent spinal nerve roots are stimulated or pressed, and a series of clinical symptoms such as lumbar pain, numbness and pain of one lower limb or two lower limbs are generated. There are many clinical methods for treating the disease, and traction treatment methods belong to one of them. Traction is primarily mechanical in force to pull the intervertebral space and relieve the internal pressure of the disc, causing the prominence to slightly relieve the compression on the nerves. At present, the main traction tool is a traction bed, and the traction bed has the defects of large occupied space, inconvenient storage, high cost and the like, so that only a hospital has the traction bed, and a patient can only go to the hospital for traction treatment, which is very inconvenient. There are some simple and easy retractors in the market at present, though occupation space is little, the cost is lower, but can not be applicable to the physiology crookedness of different crowds' waist, and application range is restricted, and unstable, the fragile of structure in the use. The invention of the prior publication No. CN105943224B discloses a lumbar disc herniation correction pad, as shown in fig. 1, although the radian of the adjustment pad 2 can be adjusted, there are the following problems, i.e., the length of the base 1 is fixed, after the radian of the pad 2 is adjusted, the base 1 is exposed outside the pad 2, so that the area of the body of the patient outside the pad directly contacts with the base 1, and the patient feels discomfort; secondly, the function is single, and the waist correction effect of the patient can be supported only through bending; thirdly, one end of the gasket 2 is clamped in the substrate 1, so that the gasket 2 cannot be parallel to the substrate 1 under the condition that the gasket is not detached, the gasket 2 is always in a bent state, the occupied space is large, and the portable type LED lamp is not convenient to carry.
