Vertebral body posterior border treater

Abstract

The invention discloses a vertebral body posterior border treater. The vertebral body posterior border treater comprises a cutter bar, wherein an antiskid handle is arranged at the upper end of the cutter bar, a cutter head is arranged at the lower end of the cutter bar, a bent part is arranged between the cutter head and the cutter bar and forms an included angle A, a locating part is arranged atthe lower end of the cutter head close to the side face of the cutter head, a nerve protecting structure and depth graduations are arranged on the frontage of the cutter head, the nerve protecting structure is arranged vertical to the frontage of the cutter head, the nerve protecting structure and the cutter head are molded integrally, a tilted cutter part with a single blade is arranged at the lower end of the cutter head and is connected with the locating part, a cutting part of the cutter part close to the locating part is a tilted upper end, and a tilted lower end of the cutting part is flushed with the other side of the cutter head. The vertebral body posterior border treater is simple in structure and reasonable in design, the risk of injuring nerves during surgical operation is lowered, and the safety of the surgical operation is improved to a large extent.

Description

technical field [0001] The invention relates to a spinal minimally invasive surgical instrument, in particular to a vertebral posterior border processor. 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 popul...

AI Technical Summary

Problems solved by technology

[0003] 1. There is no special instrument for treating the posterior edge of the vertebral body under endoscopy, and two or more instruments are required to safely process the bone

[0004] 2. Because there is no special equipment, it is necessary to find a suitable angle to treat the bone when dealing with the bone

[0005] 3. There is no protective structure for the nerve, which increases the risk of surgery

[0006] The existence of the above problems makes the unilateral dual-channel endoscopic technique limited by instruments when dealing with bone, which increases the operation time and difficulty.
