Vertebral body universal reducer used in orthopedic spine surgery

Abstract

The invention relates to the technical field of vertebral body reduction structures, in particular to a vertebral body universal reducer used in orthopedic spinal surgery, which includes several positioning locking mechanisms arranged at intervals along the length direction of the spine, and the positioning locking mechanisms It includes two locking components arranged symmetrically about the center line of the spine, the two locking components are fixedly installed on the lumbar posterior transverse process of the corresponding vertebral body, and a fixing rod is respectively installed on both sides of the spine. The fixation rod is used to realize orthopedic reduction and position limitation on both sides of the deformed spine. The present invention adopts the way of fixing the back of the waist to realize the limit fixation of the deformed spine of the human body, which can effectively ensure the correction and reset of the patient's spine; during the surgical installation, the limit fine-tuning distance can be set according to the current patient's deformation, At the same time, different sizes and types of fixing rods can be selected according to the patient's condition, and the fastening, positioning and rotation limit of different fixing rods can be realized.

Description

technical field [0001] The invention relates to the technical field of vertebral body reduction structures, in particular to a vertebral body universal reducer used in orthopedic spinal surgery. Background technique [0002] The adult spine is made up of 26 vertebrae connected by ligaments, joints and intervertebral discs. The upper end of the spine supports the skull, connects the hip bones below, attaches the ribs in the middle, and serves as the back wall of the thorax, abdomen, and pelvis. The spine has the functions of supporting the trunk, protecting the internal organs, protecting the spinal cord and performing movements. The inside of the spine forms a longitudinal spinal canal from top to bottom, with the spinal cord inside. The spine is the pillar of the body. [0003] In addition to supporting and protecting functions, the spine has flexible movement functions. Although the range of motion between two adjacent vertebrae is very small, the motions between most o...

Problems solved by technology

[0005] At present, internal fixation of the spine is often used in spinal surgery, and anterior lumbar fixation is generally used to fix the spine. However, this method of surgical fixation is difficult to achieve better results when performing surgical fixation on multiple patients with spinal deformation. The fixation effect is poor, and the overall recovery after spinal surgery is poor
