Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and more specifically, to a device for separating a neck vascular sheath from a visceral sheath through the body surface. Background Art

[0002] Cervical disc herniation is a common disease. The main reason is that on the basis of the pathological degeneration of the intervertebral disc, the outer fibrous ring of the intervertebral disc further ruptures, and the nucleus pulposus tissue protrudes (or herniates) and compresses the spinal nerve roots or spinal cord, resulting in clinical symptoms of neck pain, numbness and weakness of the limbs, and even paralysis.

[0003] The fully endoscopic anterior approach through the vertebral body bone channel technique is a new method for treating cervical disc herniation. How to percutaneously and minimally invasively establish a bone channel in the cervical vertebral body that directly reaches the lesion behind the vertebral body is an important step of this technology. During the operation, the two-finger method is used to push away important tissues such as blood vessels, trachea, and esophagus in the front of the neck and establish a safe operation area. The Kirschner wire is inserted for positioning and the C-arm is used to ensure the correct position of the puncture needle. Then the dilator and working channel are inserted step by step for expansion. Then the ring saw is inserted into the expansion channel, and the tip of the ring saw is slowly rotated until it reaches the posterior edge of the vertebral body. Finally, the separated and broken bone strips are removed by operating the ring saw.

[0004] However, during the establishment of the above-mentioned bone channel, the use of the two-finger method to establish a safe operating area inevitably requires the surgeon or assistant to maintain the operating area with at least one hand throughout the entire process, which not only reduces the surgical space, but also increases the difficulty of the operation; in addition, maintaining the operating area with fingers and maintaining the limbs as the operation progresses can easily lead to poor blood circulation and soreness, which leads to a continuous decrease in the stability of the finger maintenance, making it difficult to control the surgical risks. At present, there is no public device for assisting the establishment of cervical vertebral bone channels. Therefore, how to study and design a device for separating the cervical vascular sheath and the visceral sheath through the body surface is a problem that we urgently need to solve.
