Abstract

The invention relates to the technical field of operation tools for lumbar vertebra to solve the problem that a conventional interbody fusion cage is displaced when in use. The invention concretely relates to a self-locking stabilized structure for an interbody fusion cage. The structure comprises a fixing plate, on which a cylindrical threaded protrusion is arranged on one side used for connecting with the fusion cage. At least two locking and positioning holes are arranged in one side used for connecting with the fusion cage and arranged in the upper surface of the fixing plate opposite to the fixing plate in an oblique mode. The structure further comprises locking screws which penetrate through the locking and positioning holes and are fixedly connected with a vertebral body. The self-locking stabilized structure for the interbody fusion cage has following beneficial effects: a simple structure is obtained; a conventional fusion cage can be self-locked; displacement of the cage in a body is avoided; and internal damage is reduced.

Description

technical field [0001] The invention relates to the technical field of lumbar surgery tools, in particular to a self-locking and stabilizing structure of an intervertebral fusion device. Background technique [0002] At present, with the frequent occurrence of spinal diseases in people, the treatment methods for the spine are becoming more and more targeted. The spine consists of one vertebral body, two pedicles, two lamina, two transverse processes, four articular processes and one The bone structure composed of spinous processes is divided into cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacral vertebrae, and coccygeal vertebrae. Lumbar spine disease can be caused by bad habits or by momentary inappropriate behavior. [0003] Lumbar fusion surgery is currently the main method for treating lumbar diseases, and intervertebral fusion devices are playing an increasingly important role as an important built-in object in lumbar intervertebral interface fusion tech...
