Hidden vertebra support replacement body

Abstract

The invention relates to a hidden vertebra support replacement body, and belongs to the field of medical instruments. The hidden vertebra support replacement body comprises a supporting plate, elasticbodies are arranged at the two ends of the supporting plate respectively, transverse plates are wrapped and fixed in the elastic bodies and perpendicular to the axes of the elastic bodies, the diameter of each elastic body is not larger than that of the end surfaces of vertebrae, the two ends of the supporting plate are perpendicularly fixed to the transverse plates of the elastic bodies at the two ends respectively, the distance between the two elastic bodies corresponds to the height of lesion vertebrae, and the thickness of each elastic body corresponds to the distance between vertebrae. The hidden vertebra support replacement body is hidden in the vertebrae, does not have exposed components, does not cause complications or inflammation, replaces lesion intervertebral disc stress, completely recovers the supporting function of the lesion vertebrae, does not need to consider the fixing problem of the vertebral pedicle and the prosthesis, greatly reduces wounds, is high in fatigue resistance, does not collapse or harden, and is free of replacement all the time.

Description

technical field [0001] The invention relates to a hidden vertebra support replacement body, which belongs to the field of medical instruments. Background technique [0002] Injuries to the vertebrae of the spine often include scoliosis and other abnormal curvatures, kyphosis, degenerative disc disease, herniated discs, osteoporosis, spondylolisthesis, stenosis, tumors, and fractures. Spinal disorders resulting from injury and aging include Factors in trauma, disease, and degenerative conditions. Disorders of the spine often result in symptoms including pain, nerve damage, and partial or complete loss of motor function. [0003] Vertebral bone hyperplasia is because after middle age, vertebral bone hyperplasia increases with age, and the physiological functions of various tissue cells in the body gradually decline and age. The degenerated intervertebral disc gradually loses water, the intervertebral space narrows, and the fibrous ring relaxes. Bulge to the periphery, the ve...

Problems solved by technology

[0007] Neither of the above two operations can completely replace the work of the vertebrae, and there are more protrusions, which hinder nearby blood vessels and nerves, causing complications or inflammation

During vertebral replacement surgery, the intervertebral disc is usually replaced together. This kind of intervertebral disc usually includes two fixed plates and an elastic body between the fixed plates. The elastic body of the intervertebral disc prosthesis is usually a biocompatible However, unlike other implantable silicone products in the human body, the intervertebral disc prosthesis needs to bear a large load. The continuous pressure and deformation will lead to the fatigue of the silicone, which will eventually cause the elastic body to collapse and harden, and the intervertebral disc prosthesis will completely lose its function. , needs to be re-operated for replacement, the patient may face 2-4 replacement operations due to elastic body fatigue in his life, causing additional pain and financial burden to the patient

In addition, after the elastic body fails, the patient often cannot feel it by himself, resulting in rigid contact between the vertebrae, increasing collision and wear, and deteriorating the intervertebral environment. In severe cases, the patient will lose the possibility of reoperation
