Disposable epidural surgical device with integrated endoscope {DISPOSABLE-EPIDURAL SURGERY DEVICE INTERGRATED WITH ENDOSCOPE}

The present invention relates to an endoscope-integrated disposable epidural surgical device, and more specifically, to perform an epidural operation more easily and efficiently while checking an image through an endoscope, and to allow an accurate procedure to significantly improve the success rate of surgery, It relates to an endoscope-integrated disposable epidural surgical device that can achieve economical efficiency by having a structure optimized for epidural surgery even though it is disposable.

In general, representative examples of epidural surgery include disk surgery or stent transplantation. Representatively, the disk is a tissue containing a lot of moisture that acts as a buffer between the vertebrae and the vertebrae, and is also called the intervertebral disc.

1 is a diagram schematically showing an intervertebral disc and surrounding human tissues. If the posterior ligament 20 supporting the intervertebral disc 10 from the back is ruptured, or the intervertebral disc 10 is abnormally protruding between the vertebrae 30, nerve bundles 50 or nerves located around Compression (40) causes severe pain, which is collectively referred to as a disc, and is medically 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, an optimal surgical tool is needed to perform epidural surgery, such as minimizing risk factors and able to more effectively alleviate the symptoms of disc herniation.
