A multifunctional neural retractor

Abstract

The invention relates to a multifunctional nerve hook. The multifunctional nerve hook is characterized by comprising a nerve hook body and a handheld handle on the nerve hook body, wherein the nerve hook body is in a shape of a 90-degree hollow rod body, a light source passage parallel to the vertical hollow rod body is formed in the vertical hollow rod body, the vertical hollow rod body is a suction passage, the light source passage is shorter than the suction passage, the length of the light source passage is smaller than or equal to half of the vertical hollow rod body; an inner opening in the lower end of the suction passage is an oblique incision, and an oblique surface of the oblique incision faces forwards; the rear side of the wall of the oblique incision extends backwards at an angle of 90 degrees to form a hook groove; an oblique surface bulge is arranged below an outlet of a lower inner opening of the light source passage, an upper outer opening of the light source passage is arranged on the 90-degree transition position of the nerve hook body, and the light source enters the light source passage from the inlet; a horizontal hollow rod body of the nerve hook body is connected with the handheld handle in a sleeving manner, the middle of the 90-degree curve of the handheld handle and the nerve hook body is provided with a circular concave disc with an opening in the middle part, and the middle opening of the circular concave groove is communicated with the suction passage.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional nerve retractor. Background technique [0002] In minimally invasive spinal surgery, nerve retractors, aspirators, and light sources are all essential operating equipment and are frequently used. The minimally invasive concept of small wounds and minimal trauma will inevitably lead to the limitation of surgical operation space. In the narrow minimally invasive channel, frequent replacement of surgical instruments has brought some adverse effects on the operation process, the doctor's operation and the postoperative effect. It is manifested in: [0003] 1. Frequent replacement of equipment increases the possibility of infection; [0004] 2. Specially appointed hooks are used to attract and increase the manpower load; [0005] 3. Multiple people operate equipment, increasing the difficulty of collaboration; [0006] 4. Interfere with the operation of the main knife and incr...
