Example Embodiment

[0022] In order to better understand the purpose, structure and function of the present invention, a spinal fusion fixation device of the present invention will be described in further detail with reference to the accompanying drawings.

[0023] Such as image 3 with Figure 4 As shown, it is shown as a spinal fusion fixation device of the present invention, which is used to be implanted in the intervertebral space of the intervertebral disc, and includes a fusion cage 1. Both the upper and lower end surfaces of the fusion cage 1 are provided with protrusions 2. 2 is tapered, the convex shape extends outward and gradually becomes smaller, and the top is pointed. The fusion cage 1 is inserted into the intervertebral space of the intervertebral disc through the protrusion 2 and fixedly connected with the lamina of the intervertebral disc to prevent the fusion cage from sliding and avoid Displaced after surgery.

[0024] Furthermore, a bone graft hole 3 is provided on the fusion cage...

Abstract

The invention discloses a spine fusion fixing device used to implant in an intervertebral space of an intervertebral disk. The device comprises a fusion device (1), and the upper end face and the lower end face of the fusion device (1) are provided with bulges (2). The fusion device (1) is inserted into the intervertebral space of an intervertebral disk through the bulges and is fixedly connected with the intervertebral disk. The fusion device (1) is provided with bone grafting holes (3), and crushed bones of a human body can be put in the bone grafting holes (3) and fused with the intervertebral disk. The spine fusion fixing device has relatively good integration with a spine, and is small in wound, little in bleeding, and fast in recovery after operation. Surgery of implanting the device in a spine is fast and convenient in operation, and time and difficulty of the surgery is shortened, and cost of an implanting surgery is relatively few.

Description

technical field [0001] The invention relates to a prosthetic device, in particular to a spinal fusion fixation device for stabilizing the lumbar spine. Background technique [0002] The principle of treatment for lumbar instability is that for patients with obvious nerve compression symptoms that are not relieved after conservative treatment, it is listed as an indication for surgical treatment. The initial surgical treatment is spinal canal decompression and discectomy. The protruding nucleus pulposus and annulus fibrosus tissue are removed by incision of the intervertebral disc through the posterior approach, so as to expand the decompression of the spinal canal and release the compression on the spinal cord and nerve roots. However, because the resection of the lamina destroys the structure of the spine, it will cause new instability factors in the spine and the compression of the intervertebral space has not been restored, resulting in a high recurrence rate after surger...
