Interbody fusion fixator for lateral anterior-approach vertebral reconstruction

Abstract

The invention discloses an interbody fusion fixator for lateral anterior-approach vertebral reconstruction, which relates to the field of medical instruments, and aims to solve the technical problem of providing a fusion fixator used in cooperation with a cervical lateral anterior approach operation. The technical scheme adopted by the invention is as follows: the interbody fusion fixator for lateral anterior-approach vertebral reconstruction comprises a fusion fixing body and screws, the fusion fixing body comprises a vertebral body fusion part and an intervertebral fusion part; the vertebralbody fusion part is of a columnar structure in the vertical direction; the vertebral body fusion part comprises front, back, left and right side faces as well as top and bottom faces, a first bone grafting cavity is formed between the top and bottom faces, a second bone grafting cavity is formed between the left and right side faces, the upper portion of the left side face, the lower portion of the left side face, the upper portion of the right side face or the lower portion of the right side face of the vertebral body fusion part is connected with an interbody fusion part; the fusion fixingbody is further provided with at least two screws which are used for being fixed to a relatively large residual vertebral body and adjacent vertebral bodies on the upper side and the lower side respectively. The interbody fusion fixator is suitable for cervical lateral anterior approach surgery.

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.
