Surgical instrument guider, intervertebral foramen grinding drill and intervertebral foramen forming surgical device

Abstract

The invention relates to a surgical instrument guider, an intervertebral foramen grinding drill and an intervertebral foramen forming surgical device. The surgical instrument guider comprises an instrument channel and a guider body which is used for guiding a surgical instrument; the guider body is movably arranged in the instrument channel; both the instrument channel and the guider body are of hollow cylindrical structures; the diameter of the guider body is smaller than that of the instrument channel; and the surgical instrument extends into the guider body and is arranged movably. The intervertebral foramen grinding drill comprises the surgical instrument guider, wherein the surgical instrument is a grinding drill body. The intervertebral foramen forming surgical device comprises the intervertebral foramen grinding drill and an intervertebral foramen mirror; and the intervertebral foramen mirror and the intervertebral foramen grinding drill are connected side by side. The surgicalinstrument guider provided by the invention can realize effective guide of the surgical instrument; the position of the surgical instrument guider-based intervertebral foramen grinding drill is controlled accurately; the working range is large; and the intervertebral foramen forming surgical device can grind and remove bones to complete large-range intervertebral foramen forming under direct viewof the intervertebral foramen mirror, and a surgical operation is safer.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical instrument guide, an intervertebral foramen drill and an intervertebral foramen shaping operation device. Background technique [0002] The transforaminal minimally invasive spinal technique represents a new concept of minimally invasive spinal surgery, which can carry out disc herniation, foramina formation and annulus fibrosus repair in all segments from the cervical spine to the lumbar 5 sacral 1 segment. Satisfactory curative effect of surgery can reach 75% to 90%. Due to its many advantages, the current international field of minimally invasive spinal surgery has recognized the dominance of transforaminal surgery in this field. [0003] It is the key to the success of the operation that the grinding and drilling channel of the transforaminal mirror can be successfully established, and the foramina formation is the most critical step in establishing the channel....

AI Technical Summary

Problems solved by technology

[0004] 1. The position of the intervertebral foramen mirror drill is difficult to control during the bone grinding process, and it is easy to deviate. At the same time, the working range of the intervertebral aperture drill is small, generally within the diameter range of the intervertebral foramen mirror drill channel ;

[0005] 2. The intervertebral foramen cannot grind away the bone and remove the obstacle under the direct vision of the endoscope, but rely on X-ray perspective to repeatedly confirm the position of the bone and obstacle by grinding and drilling to prevent nerve injury

In this way, X-rays are repeatedly fluoresced, and the doctor and patient are exposed to too much X-rays, which greatly prolongs the operation time.
