The present invention relates to a dilated spinal nerve hole in the spinal stenosis patients and to fix the spine to maintain the dilated state of the neural cavities and to maintain a soft spinal anchoring mechanism.

The spine acts as a girder of the human body that gathers various structures to support the weight of the upper body. It consists of seven cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and sacrum and lumbar vertebrae from the hip. It is a flexing and stretching exercise that serves as a joint to perform various tasks along with the upper and lower extremities. It also serves as a pathway for the spinal nerve root, which is the shape of the central nervous system and the peripheral nerve, as well as a reservoir of calcium, an essential mineral for our body for survival. Do it.

1 to 3 is a view schematically illustrating the general contents of the spine prior to the full description of the neural hole expansion and soft spinal fixture according to an embodiment of the present invention. 1 is a partial perspective view of the spine, FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1, and FIG. 3 is a side cross-sectional view of the spinal column having spinal stenosis.

As shown in Figures 1 to 3, the spine is composed of a plurality of vertebrae (A1, A2, A3) is connected up and down. The vertebrae A1, A2, and A3 have a plurality of unit vertebral bodies 11 interposed therebetween with a disc 15 interposed therebetween, and are integrally connected to each unit vertebral body 11 toward the back of the human body. An extended spinous process 27, a transverse process 21 that protrudes from left and right, respectively, and a corrugated protrusion 25 positioned between the spinous process 27 and the transverse protrusion 21; It comprises a lower joint projection (19).

In addition, the back joint 29 is located between the coronary projections 25 and the lower joint projections 19, and the spinal cavity 13 is passed between the vertebral bodies 11 and the spinous processes 27 by the spinal nerve 13. (17) is formed. The spine hole 17 extends along the longitudinal direction of the vertebral body 11 connected up and down to form a pipe as shown in FIG. 3.

In addition, as shown in FIG. 2, the left and right intervertebral holes 31 are formed between the disk 15 and the left and right rear joints 29, through which the branch nerve 23 connected to the spinal nerve 13 passes. Is connected to other nerve tissue.

On the other hand, as you get older, your strength decreases, your physical function gradually degenerates, and your body starts to show various abnormalities. These degenerative symptoms also appear on the spine. As the spine ages, the water content of the disc 15 drops and gradually loses its elasticity and is flatly deformed to protrude outward from the original position, causing pain by touching the spinal nerve 13 or other peripheral nerves.

In addition, as the elastin component of the left and right rear joints 29 is removed and the collagen component is filled in place, the posterior joint may expand to the intervertebral cavity 31 to press the branch nerve 23. . In addition, when the yellow ligament 33, which is an elastic fiber dedicated to the spinal nerve 13, is degenerated, as shown in FIG. 3, the elastic fiber is gradually destroyed and collagen fibers are thickened to compress the spinal nerve 13.

Due to the various degenerative changes as described above, the spinal cavity 17 and the intervertebral cavity 31 are gradually narrowed, causing pain by pressing the spinal nerve 13 and the branch nerve 23 passing therethrough. This condition is called spinal stenosis.

The spinal stenosis causes pain in the lower limbs or lower back so that walking can not be long. Its treatment method is a treatment method by drug treatment, physical therapy or surgery. The treatment method by the surgery is to do when other treatment methods are ineffective, by removing the bones and tissues squeezing nerves to remove the pain by expanding the narrowed neuralgia. This is to remove bone and tissue, so spine fusion is performed to eliminate the possibility of anxiety after the operation.

However, the surgical method is to remove the bones and tissues that make up the spine, which requires general anesthesia, and the elderly who have weak energy due to long operation time and recovery period are not able to actually operate and are especially satisfied by causing various complications. Sometimes no results are obtained.

In addition, the spinal fusion technique is a surgery for immobilizing two or several adjacent vertebrae, and thus, the structure is complicated because a plurality of metal rods or screws are used, such as fixing a screw or screw to the spine after removing a bone or ligament tissue that compresses nerves. In particular, there is a problem that may occur when the procedure can not but destroy the normal joint.
