Treatment fixer for lumbar disc herniation

Abstract

Treatment fixator for lumbar disc herniation, including upper pedicle screw, lower pedicle screw, lateral facet screw, triangular fixation frame, screw guide cylinder and guide plate, triangular fixation frame includes upper fixation cap, lower fixation cap, left side The oblique fixing cap, the upper horizontal connecting column, the lower vertical connecting column and the left oblique connecting column, the left end of the upper horizontal connecting column is fixedly connected with the left oblique fixing cap, and the right end of the upper horizontal connecting column is fixed with the upper fixing cap Connection, the upper end of the lower vertical connecting column is fixedly connected with the upper fixing cap, the lower end of the lower vertical connecting column is fixedly connected with the lower fixing cap, the lower end of the left oblique connecting column is fixedly connected with the lower fixing cap, and the left oblique connection The upper end of the column is fixedly connected with the left oblique fixing cap, and the upper pedicle screw, the lower pedicle screw and the lateral facet screw form a stable triangular fixed relationship, achieving the purpose of firm fixation, realizing minimally invasive surgery, and greatly improving the operation efficiency .

Description

technical field [0001] The invention relates to a treatment fixer for lumbar intervertebral disc herniation. Background technique [0002] With the change of lifestyle in modern society, office workers sit and work for a long time, resulting in more and more diseases such as lumbar disc herniation, discogenic low back pain and lumbar instability. If conservative treatment fails, surgery is required. Lumbar fusion is widely used to treat diseases such as lumbar disc herniation, discogenic low back pain and lumbar instability. During the treatment process, a high-strength fixator is required. The existing fixer consists of two simple screws and a very thin Composed of traditional metal rods, this traditional classic fixation method is not very firm, and needs to peel off the muscles on both sides of the human body, and then fix them with two sets of fixators, which makes the patient suffer more pain and cannot achieve minimally invasive surgery , The screw is easy to deviate...

Lumbar fusion is widely used to treat diseases such as lumbar disc herniation, discogenic low back pain and lumbar instability. During the treatment process, a high-strength fixator is required. The existing fixer consists of two simple screws and a very thin Composed of traditional metal rods, this traditional classic fixation method is not very firm, and needs to peel off the muscles on both sides of the human body, and then fix them with two sets of fixers, which makes the patient suffer more pain and cannot achieve minimally invasive surgery , the screw is easy to deviate when it is screwed in and fixed, the accuracy rate is not high, and it is easy to be misplaced, resulting in spinal cord, nerve root and other injuries
