Lumbar zygapophysis fusion screw fixing positioner and using method thereof

Abstract

The invention discloses a lumbar zygopophysis fusion screw fixing positioner and a using method thereof. The lumbar zygopophysis fusion screw fixing positioner comprises a positioner body, a positioning guide needle, a sighting device sleeve and a sighting guide needle. The positioner body comprises a longitudinal connecting rod, a positioning guide needle connecting rod, a transverse connecting rod, a sighting device sleeve support and a locking screw. The longitudinal connecting rods and the transverse connecting rods are movably connected to form a parallelogram structure; the sighting device sleeve support is fixed to the lower end of the longitudinal connecting rod. The sighting device sleeve is installed on the sighting device sleeve support. The sighting device sleeve is used for inserting a sighting guide needle; the positioning guide pin connecting rod is movably connected with the transverse connecting rod; a positioning guide pin is mounted in the positioning guide pin connecting rod; a fastening screw for fixing the positioning guide pin is arranged at the end part of the positioning guide pin connecting rod; the middle section of the needle body of the positioning guide needle is provided with a limiting buckle. The intervertebral disc/gap fusion minimally invasive surgery screw implantation device is simple in structure, screw implantation of the intervertebral disc/gap fusion minimally invasive surgery can be accurately achieved, the surgery efficiency is improved, the surgery risk is reduced, damage to nerves and blood vessels is avoided, and the intervertebral fusion effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a lumbar articular process fusion screw fixation locator; in addition, the invention also relates to a method of using the lumbar articular process fusion screw fixation locator. Background technique [0002] Lumbar disc herniation, lumbar instability, lumbar spondylolisthesis and other lumbar degenerative diseases account for a considerable proportion of current orthopedic outpatient clinics. Such diseases will cause persistent pain and inability to engage in physical labor for patients, and seriously affect the quality of life of patients. For this type of disease, the method of intervertebral joint screw implantation and fusion is mostly used in clinical treatment. In the process of this operation, the screw implantation and fixation of the intervertebral joint is the key to the whole operation. The current mainstream surgical method is percutaneous operati...
