MANUFACTURING METHOD OF DISPOSABLE-EPIDURAL SURGERY TOOL INTERGRATED WITH ENDOSCOPE AND DISPOSABLE-EPIDURAL SURGERY TOOL INTERGRATED WITH ENDOSCOPE MANUFACTURED BYE}

The present invention relates to a method of manufacturing an endoscope-integrated epidural surgical instrument, and to an endoscope-integrated epidural surgical instrument manufactured thereby, and more particularly, to perform an epidural operation more easily and efficiently while checking an image through an endoscope. An epidural surgical instrument that can be operated and can significantly improve the success rate of surgery can be easily manufactured, and a method of manufacturing an endoscopic integrated epidural surgical instrument that can be manufactured functionally and economically by having an optimized structure, and It relates to an endoscopic integrated epidural surgical instrument.

Lower extremity pain is a collective term for pain in the lower back and legs. Lower extremity pain is one of the common diseases that anyone can experience in life. Among the causes of absenteeism among adults under 55 years of age, it is the second most common symptom after a cold, and the cause of chronic pain is followed by headache.

Recently, with the rapid increase in spinal surgery, many patients return to the hospital due to the so-called failed back surgery syndrome, where lumbar pain recurs or worsens after surgery.The outer part of the dura surrounding the spinal cord, that is, the epidural space. ) Is known to be the main cause of pain due to adhesion and fibrosis.

The epidural space refers to the space between the dura, which is a protective membrane surrounding the spinal cord, and the spinal canal, and is a tissue rich in nerve fibers, adipose tissue, connective tissue, blood vessels, and lymphatic vessels.

Specifically, the epidural space can be divided into an anterior epidural space and a posterior epidural space. The anterior epidural space is surrounded by the yellow ligament and the periosteum of the vertebral body. The vertebral body, the intervertebral disc, and the posterior subsidiary ligament are located on the front side, and the dura mater is located on the rear side. In addition, the anteroposterior diameter of the posterior epidural space is known to be about 20 to 60 mm.

The adhesion of the epidural space occurs after spinal surgery in many cases, but it also frequently occurs in intervertebral disc herniation and degenerative spinal canal stenosis. In intervertebral disc herniation, the nucleus in the disc escapes laterally or posteriorly through the torn gap of the posterior fibrous annulus, causing deposition of cells in the epidural space and inflammatory reactions, resulting in adhesion, and in spinal stenosis, adhesions occur by inflammatory mediators. Regardless, in the case of chronic lumbar pain patients, it is judged that adhesions are accompanied in a large part. When adhesion occurs in the epidural space, it may cause pain by interfering with inflammation of the nerve roots in the epidural space and the motility of the dural sleeve of the nerve roots. In addition, these adhesions interfere with the flow of venous blood flow in the epidural space, causing swelling of the neuromuscular muscles. Therefore, if there is adhesion between the dura mater and the posterior ligament, the adhesion itself may cause pain, and chemical stimulation of the dura mater and nerve roots may cause pain.

In other words, abnormal amounts of inflammatory substances such as substance P, calcium gene-related peptide, c-fos, and phospholipase A2 are present in the entire epidural space of the compressed nerve tissue, thereby causing inflammatory reactions and pain.

Another major cause of lumbar pain is spinal canal stenosis, which is caused by the narrowing of the intervertebral cavity through which the spinal canal or nerve passes by the intervertebral joints, yellow ligaments, and discs that make up the spinal canal.

If the lower lumbosacral pain is caused by these two diseases, severe pain is felt in the lumbar and lower extremities, and in some cases, it is impossible to walk far or for a long time.

The best treatment for these two diseases is to remove the adhesions in case of epidural adhesions, and to relieve pressure on nerves and blood vessels by widening the stenosis in case of spinal canal stenosis. Of course, if the above treatment is performed through surgery, there is an advantage in that the root cause can be eliminated. However, since it is expensive and the frequency of operation failure and recurrence is high, non-surgical methods have been mainly attempted in recent years.

Typically, there is a method of injecting a drug that suppresses inflammation or swelling by inserting a needle into the cervical cavity of the epidural space or the spine. However, when there is adhesion, the drug does not reach or spread sufficiently to the target point, and when fibrosis progresses due to severe adhesion, it hardly responds to the anti-inflammatory action of steroids, so there is a limit to the relief of symptoms and treatment results are poor. Therefore, in clinical practice, medical devices have been required to more effectively and safely alleviate adhesions of the epidural space and stenosis of the spinal canal.

1 is a diagram schematically showing the intervertebral disc and the surrounding human tissue. In general, representative examples of epidural surgery include disk surgery or stent transplantation. If the intervertebral disc 10 is supported from the back, the posterior ligament ( 20) is ruptured, or the intervertebral disc 10 is abnormally protruding between the vertebrae 30, compressing the nerve bundles 50 or nerves 40 located in the vicinity to cause severe pain. It is collectively referred to as a disc, and medically it is referred to as herniation of intervertebral discs.

In the case of an onset of an intervertebral disc herniation, the surrounding nerves are treated to relieve pain, or in more severe cases, an operation to remove the prolapsed part of the disc is performed. However, disc removal surgery not only has the burden of incisional surgery, but also takes several days of recovery time, and may raise concerns about sequelae caused by the disc removal.

Therefore, there is a need to economically manufacture an optimal surgical tool for performing epidural surgery, such as minimizing risk factors and able to more effectively alleviate the symptoms of disc herniation.
