Lumbar disc herniation correction device

Abstract

The invention belongs to the technical field of medical instruments and mainly relates to a lumbar disc herniation correction device which comprises an elastic gasket. Each of two ends of the elasticgasket is connected with a pull rod, the outer wall of each pull rod is axially provided with a clamping groove, the elastic gasket is connected in the clamping grooves in a clamped manner, the pull rod at the left end is connected with a first adjusting plate through a connecting member, the pull rod at the right end is connected with a second adjusting plate through a connecting member, a firstguide rod and a threaded rod are arranged at the right end of the first adjusting plate, an L-shaped mounting groove is formed at a position, of a second blind hole, at the top end of the second adjusting plate, a first bevel gear and a second bevel gear are arranged in the L-shaped mounting groove, an adjusting rotation shaft is connected on the first bevel gear, the second bevel gear is connected on the threaded rod in a threaded manner in the L-shaped mounting groove, and the first bevel gear and the second bevel gear are meshed. The lumbar disc herniation correction device can adjust radian and height of the elastic gasket in a stepless manner to adapt to physiological bending degree of waists of different populations and is convenient to carry and good in correction effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for correcting lumbar disc herniation. Background technique [0002] Lumbar disc herniation is one of the more common diseases, mainly because various parts of the lumbar intervertebral disc (nucleus pulposus, annulus fibrosus and cartilage plate), especially the nucleus pulposus, have degenerative changes to varying degrees, and under the action of external forces , the annulus fibrosus of the intervertebral disc ruptures, and the nucleus pulposus tissue protrudes (or protrudes) from the rupture to the rear or in the spinal canal, causing the adjacent spinal nerve roots to be stimulated or compressed, resulting in low back pain, numbness and pain in one or both lower limbs and other clinical symptoms. There are many ways to treat this disease clinically, traction therapy is one of them. Traction mainly pulls the intervertebral space with mechanical...

AI Technical Summary

Problems solved by technology

At present, the main traction tool is the traction bed, but the traction bed has the disadvantages of large space occupation, inconvenient storage, and high cost. Furthermore, only hospitals have traction beds, and patients can only go to the hospital for traction treatment, which is very inconvenient

There are some simple retractors currently on the market. Although they occupy a small space and are low in cost, they are not suitable for the physiological curvature of the waist of different groups of people. The scope of use is limited, and the structure is unstable and easily damaged during use.

The existing publication number is the authorized invention patent of CN105943224B, a kind of lumbar disc herniation correction gasket, such as figure 1 As shown, although the arc of the gasket 2 can be adjusted, there are the following problems. First, the length of the base 1 is fixed. After the adjustment of the arc of the gasket 2, the base 1 will be exposed to the outside of the gasket 2, causing the patient's body to be in the position of the gasket. The outer area will be in direct contact with the base 1, causing discomfort to the patient; 2, the function is single, and the correction effect of the patient's waist can only be supported by bending; When the sheet is disassembled, it is impossible to make the gasket 2 parallel to the base 1, and the gasket 2 will always be in a bent state, which takes up a lot of space and is not easy to carry
