Multifunctional nerve drag hook

Abstract

The invention discloses a multifunctional nerve drag hook. The multifunctional nerve drag hook comprises a handle and a drag hook body, the handle and the drag hook body are integrally formed, an included angle is formed between the handle and the drag hook body, protruding strips are arranged on the two sides of the upper end of the outer side face of the drag hook body, a U-shaped groove is formed in the outer side of the drag hook body, a drag hook head is arranged at the lower end of the drag hook body, the drag hook body and the drag hook head are integrally formed, one side of the drag hook body at the upper end of the drag hook head is provided with a nerve baffle, the outer side face of the drag hook body is a concave surface, and depth scales are arranged on the concave surface. The multifunctional nerve drag hook is simple in structure and reasonable in design, the probability of injuring human tissues in the operation process can be reduced, the operation time is advantageously shortened, and the operation success rate is increased.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a multifunctional nerve retractor. Background technique [0002] There are two commonly used techniques for the treatment of spinal diseases such as disc herniation, intervertebral stenosis, and intervertebral fusion, one is minimally invasive transforaminal endoscopy, and the other is traditional open surgery. The development of minimally invasive spinal endoscopic technology is becoming more and more mature, especially the transforaminal endoscopic technology is rapidly popularized nationwide. Foraminal endoscopic technology is a single channel, the scope of the operative field is affected, and the use of surgical instruments is limited. It has advantages in the treatment of intervertebral disc herniation, but it is more difficult in the treatment of other spinal diseases such as intervertebral stenosis. A new minimally invasive surgery is currently popular, unilateral dual-cha...

AI Technical Summary

Problems solved by technology

[0003] 1. When the herniated nucleus pulposus is at the nerve bifurcation, the traditional nerve root retractor cannot fully reveal the herniated nucleus pulposus;

[0004] 2. If it cannot be fully exposed, there will be problems such as insufficient decompression and damage to other healthy tissues;

[0005] 3. Increased operation time and increased operation risk

[0006] The existence of the above problems increases the operation time and increases the difficulty of the operation
