Description

Medical device for intervertebral spinal cord spacer implantation procedure {INTERSPINOUS PROCESS SPACER INSERTION HOLDER}

The present invention relates to a medical device for implant implantation for the treatment of the vertebral body, and more particularly to a medical device for implantation of the intervertebral fluid intervertebral fixation implants, in particular implanted between the vertebral posterior spinous process to suppress stenosis between the spinous process It relates to a medical device for a spinal body spinal process spacer implantation procedure.

Recently, as the elderly population increases, patients with spinal stenosis accompanying low back pain or lower extremity pain due to neural pressure caused by degenerative changes in the spine are increasing. Such degenerative lumbar spinal canal stenosis is a nerve compression caused by narrowing of the spinal canal, intervertebral cavity, and nerve roots due to degeneration of the lumbar spine, causing pain, numbness, and cramps in the lower back, hips, and legs, and causing nervous system disorders. It is known as a disease.

As a conventional surgical treatment for the disease caused by lumbar spine degeneration as described above, a fusion of a rigid fixation concept using a metal rod and a pedicle screw has been performed. In the case of the problem of accelerating the degeneration of the procedure and adjacent areas by limiting the movement of the treatment site has been reported.

On the other hand, recently, in order to supplement the problems of the above-mentioned fusion surgery, implantation of the Posterior Dynamic Stabilization of the semi-rigid fixation concept that can stabilize the vertebral body procedure and move flexibly Procedures have been developed and applied to patients.

The posterior fluid intervertebral fixture is implanted for spinal therapy, which is designed to prevent the lumbar nerve from folding or causing pain when a person is standing as it is implanted in the space between the two lower back bones called spinous processes. It is used as a therapeutic device to reduce pain and improve physical function.

In addition, the posterior fluid intervertebral fixture may include an interspinous spinal spacer, a flexible material based on a pedicle based dynamic system, and a posterior joint fixture according to the purpose of the procedure or the site and clinical condition. Facet Arthroplasty), and various kinds of products are researched and developed according to materials, designs and treatment methods, and are widely used as medical products for the treatment of spinal diseases.

That is, the posterior fluid intervertebral fixation as described above is recognized as a clinically proven device that treats major symptoms of lumbar spinal canal stenosis (LSS), thereby improving patient satisfaction and succeeding as a whole. U-shaped fixture (Interspinous-U®), developed by Fixano, and St. Developed by Francis Medical Technologies, X STOP (X STOP®) is well known as a spacer used in spinal cord implantation.

On the other hand, however, it has been pointed out that the U-shaped fixation mechanism has a very large rigidity and completely restricts the extension, which may cause degeneration of other adjacent lumbar segments like fusion. In addition, in the case of the procedure using the above-mentioned X-STOP, the wing is separated after being inserted in a state in which one wing is separated, so that the procedure is inconvenient and the procedure time is long.

On the other hand, the present applicant has developed a spinal spine period spacer improved to shorten the procedure time and improve the ease of treatment by local incision compared to the conventional medical treatment for spinal disease (Patent No. 10- 2011-0087250).

1A and 1B are schematic views illustrating spinal spinous process spacers 10, which have been developed and patented by the present applicant, respectively. Referring to this, FIG. 1A and FIG. It has a configuration including a pair of departure prevention member (33) (43). The spinous process spacer 10 having such a configuration is inserted and implanted between spinous processes S at the side of the vertebral body as illustrated in FIGS. 2A and 2B.

That is, referring to FIGS. 1A to 2B, the spine spinous process spacer 10 having the above-described configuration has a pair of departure preventing members 33 and 43 entering the spinous process S from the side of the vertebral body 1. While being gradually rotated and implanted to be caught on the rear part of the spinous process (S), it has a configuration designed to allow the procedure by the minimal incision of the surgical site.

By the way, in the case of the spinal spinal process spacer 10 having the block-shaped body having the above-described configuration, for example, a state of holding the main body 20 of the spacer 10 by using a thin stick holder or the like during the procedure In a small hammer or a surgical tool (not shown), such as a punch is implanted to be inserted into the space between the spinous process (S) from the side of the spine (1).

Therefore, in the conventional conventional spinous process spacer, in particular, the spacer having a block-type body, there is a problem that the pain can be applied to the patient during the implantation procedure as described above, and the implantation precision of the surgical site during the local incision procedure and There is a problem that has a limitation in increasing the ease of the procedure.

Accordingly, the present invention has been made in view of the problems with the conventional vertebral spinous process spacers, in particular the spinal process spacer implantation medical device having a block-shaped body as described above to solve this problem, an object of the present invention is a spinal process spinous process It is to provide a medical device for spacer implantation procedure for spinal vertebral spinous process that can improve the procedure precision and ease of the procedure of the implantation process by inserting the spacer in between.
