Lateral anterior Approach Vertebral Body Reconstruction Intervertebral Fusion Fixator

Abstract

The invention discloses an intervertebral fusion fixator for vertebral body reconstruction through a lateral anterior approach, relates to the field of medical instruments, and solves the technical problem of providing a fusion fixator used in conjunction with cervical lateral anterior approach surgery. The technical scheme adopted in the present invention is: the intervertebral fusion fixator for vertebral body reconstruction through the lateral anterior approach, including a fusion fixation body and screws, the fusion fixation body includes a vertebral body fusion part and an intervertebral fusion part, and the vertebral body fusion part is vertically Columnar structure, the fusion part of the vertebral body includes four sides, front, back, left and right, and top and bottom surfaces, the first bone graft cavity is set between the top and bottom surfaces, the second bone graft cavity is set between the left and right sides, the upper part of the left side of the vertebral body fusion part, the left side The lower part of the side, the upper part of the right side, or the lower part of the right side are connected to the intervertebral fusion part, and the intervertebral fusion part is provided with a third bone graft cavity; the fusion fixation body is also provided with at least two screws, which are respectively used for relatively large The residual vertebral body and the upper and lower adjacent vertebral bodies are fixed. The present invention is applicable to cervical spine lateral anterior approach operation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intervertebral fusion fixator in orthopedic medicine. Background technique [0002] Anterior cervical corpectomy decompression and fusion (ACCF) is suitable for patients whose spinal cord decompression cannot be obtained by simple discectomy. For patients with both anterior spinal cord compression and posterior spinal cord compression, combined posterior spinal canal enlargement surgery may be considered on the basis of ACCF. For patients with vertebral body lesions (tumor, etc.), cervical dislocation, and kyphosis, ACCF is also an ideal choice. Anterior cervical plate, titanium mesh and other implant materials can improve the initial stability, support strength and bone graft fusion rate of ACCF surgery. [0003] According to the physiological structural characteristics of the vertebral body, there are esophagus and trachea in front of the cervical vertebral body. The exi...

AI Technical Summary

Problems solved by technology

If forcibly using existing instruments for fusion fixation, the following problems will occur: (1) Implantation cannot be performed, and the surrounding normal structures will be damaged even if implanted; (2) Cannot be fixed; (3) Anterior fibrous annulus and ligaments will be damaged , Violent stretching can damage the surrounding muscles, ligaments, nerves and other structural tissues

However, the operation space of the lateral anterior surgical approach is small, and the existing fusion fixator cannot be used for screw fixation and other operations from the lateral approach. Therefore, there is a lack of a fusion fixator that is compatible with the lateral anterior approach of the cervical spine.
