Porous integrated cervical vertebral fusion cage

Abstract

The invention discloses a porous integrated cervical vertebral fusion cage, relating to the technical field of medical apparatus and instruments. The porous integrated cervical vertebral fusion cage comprises a main body part and a fixing plate, wherein the main body part is used for being inserted into adjacent vertebral bodies, and the main body part is of a porous bone trabecula structure; thefixing plate is connected to the rear end of the main body part, the top end of the fixing plate protrudes out the top surface of the main body part, the bottom end of the fixing plate protrudes out the bottom surface of the main body part, fixing holes used for connection with the vertebral body are formed in the top end and the bottom end of the fixing plate, the front side of the fixing plate is provided with a fusion layer used for attaching to the vertebral body, and the fusion layer is of a porous bone trabecula structure. The porous integrated cervical vertebral fusion cage provided bythe invention is embedded in the vertebral body through the fixing plate, the material of the bone trabecula at the front side of the fixing plate is gradually fused with the cervical vertebra, so that the main body part is prevented from sliding out from the vertebral bodies, and thus the stable fusion between the porous integrated cervical vertebral fusion cage and the vertebral body is realized. The fixing plate is completely embedded in the vertebral body, the porous bone trabecula structure and the vertebral body realize fusion gradually, then connection is realized, and the fixing platecan not protrude out of the outer surface of the vertebral body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-hole integrated cervical fusion device. Background technique [0002] Cervical disc herniation is a common disease in spinal surgery. At present, the effective treatment method for cervical disc herniation is cervical surgery, which is to restore the intervertebral height and the physiological curvature of the cervical spine, so that the cervical spine can be stabilized immediately. Intervertebral fusion is commonly used to treat conditions such as spinal degeneration and instability by restoring intervertebral height, widening the intervertebral foramina, supporting the anterior column, and increasing the stability of the fused segment. Since Kuslich et al first used intervertebral fusion for human lumbar intervertebral fusion in 1988, intervertebral fusions of various manufacturing techniques, materials, and shapes have gradually appeared and been applied in cli...
