Problems solved by technology

[0004] However, the instrument channel of the currently used intervertebral foramina mirror is a closed circular channel, and the surgical instruments need to extend into the lesion from the instrument channel, so the size of the instrument must be smaller than the size of the instrument channel, so that it can be used under the intervertebral foramina mirror. The size of the equipment ...

Abstract

The invention discloses an intervertebral foramen mirror which comprises a main structure and a working mirror tube connected with one end of the main structure. An instrument passage penetrating two ends of the intervertebral foramen mirror is arranged on the working mirror tube and the main structure, and an opening is formed in the side wall of the instrument passage. An operating instrument inserting mode is added, and a knife head portion for cutting tissue can be made in larger size, so that working efficiency and strength of an operating instrument are improved, operating operation is enabled to be simpler and more efficient, and the operating instrument is durable.

Description

technical field [0001] The invention relates to a medical device, in particular to an intervertebral foramina mirror. Background technique [0002] The purpose of the transforaminal minimally invasive spinal technique is to establish a working channel from the side or rear of the patient's body to enter the intervertebral foramen, and to completely remove the protruding or prolapsed spinal cord outside the safe triangle of the intervertebral foramen and the fibrous annulus of the intervertebral disc. Nuclei and hyperplastic bone to relieve the pressure on the nerve root, relieve the obstruction of lateral recess circulation caused by disc herniation, nerve root edema and aseptic inflammation again, resulting in recurrence of clinical symptoms. The operation method is a spinal minimally invasive surgery system composed of a specially designed intervertebral foramenoscope, corresponding supporting spinal minimally invasive surgical instruments, imaging and image processing sys...
