Abstract

The invention relates to medical instruments, and discloses an intervertebral foramen mirror puncturing system. The intervertebral foramen mirror puncturing system comprises a one-level cannula, a two-level cannula, an opening awl, an anchor needle and a ring saw. The awl head of the opening awl is provided with a protection shoulder, the head end of the anchor needle is provided with a self-tapping thread and is blunt, the blunt head of the anchor needle is designed not to cause hurt easily when penetrating through the zygopophysis to be close to the nerve, and the bone way can be adjusted more easily and conveniently through the self-tapping thread of the head end of the anchor needle. The ring saw is used for cutting the zygopophysis from the side face by the angle by which the anchor needle enters the canalis vertebralis to expand the bone way until the diameter of the bone way is enough for an endoscope to be placed. By means of the intervertebral foramen mirror puncturing system, the puncturing process of the lumbar vertebra intervertebral foramen mirror operation is obviously simplified, operation is reliable and practical, the operation safety and the operation successful rate are improved, and the parts, exposed to the radiation, of an operator and a patient are greatly reduced.

Description

Technical field [0001] The present invention relates to medical equipment, in particular to an intervertebral foraminal puncture system. Background technique [0002] As we all know, intervertebral disc herniation is a common disease that brings great pain to patients. Treat this disease. Traditional surgery includes lamina fenestration and nucleus pulposus removal and posterior laminectomy, spinal canal decompression, and pedicle screw fixation. The surgical trauma is large, bleeding is much, and postoperative recovery time is long, especially when spine internal fixation is performed. The adjacent lumbar spine is prone to complications such as accelerated degeneration, which brings new discomfort to the patient. Among them, internal fixation is to fix the lumbar spine with instruments such as screws. [0003] Chinese patent number 201020186910.0 discloses a "cervical intervertebral disc minimally invasive surgery system", which improves the tools for cervical percutaneous punc...
