Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention is further described:

[0033]As shown in the accompanying drawings, a four-way deployment intervertebral fusion device is characterized in that the intervertebral fusion device is composed of a four-way deployment fusion mechanism and a driving distraction mechanism. The four-way deployment fusion mechanism consists of a front upper support Opening plate 1, front lower opening plate 2, rear upper opening plate 3 and rear lower opening plate 4 are formed, and described front upper opening plate 1 is made up of front side plate and upper side plate, and described front lower The expansion plate 2 is composed of a front slide plate and a lower plate, the rear upper expansion plate 3 is composed of a rear slide plate and an upper slide plate, and the rear lower expansion plate 4 is composed of a rear side plate and a lower side plate. The upper end of the front side plate in the front upper expansion pla...

Abstract

The invention relates to the technical field of interbody fusion cage medical instruments, in particular to a four-way expanding interbody fusion cage. The interbody fusion cage is characterized by being composed of a four-way expanding fusion mechanism and a driving spreading mechanism, the four-way expanding fusion mechanism is composed of an upper front spreading plate, a lower front spreadingplate, an upper rear spreading plate and a lower rear spreading plate, the upper front spreading plate is composed of a front side plate and an upper side plate, the lower front spreading plate is composed of a front sliding plate and a lower sliding plate, the upper rear spreading plate is composed of a rear sliding plate and an upper sliding plate, and the lower rear spreading plate is composedof a rear side plate and a lower side plate. The four-way expanding interbody fusion cage has the advantages that by utilizing the spreading force of the interbody fusion cage, the height and tensionof the vertebral joints are restored, the compression is relieved, the physiological curvature of the spine is restored, and the stable four-way expansion of the spine is ensured through the bone fusion of the interbody fusion cage.

Description

technical field [0001] The invention relates to the technical field of intervertebral fusion device medical equipment, in particular to a method of utilizing the distraction force of the intervertebral fusion device to restore the height and tension of the vertebral joints, realize the release of compression, restore the physiological curvature of the spine, and intervertebral fusion Bone fusion, a four-way intervertebral fusion device that ensures spinal stability. Background technique [0002] As we all know, degeneration of the spine is more common in orthopedic clinics. Common degeneration of the intervertebral disc, spinal stenosis, spondylolisthesis, and compression of the spinal cord or nerve roots often require surgical treatment to completely relieve the compression, restore the physiological curvature of the spine, and protect the spine. Stablize. In addition, some patients with spinal deformity, trauma, tumor, revision surgery and infection sometimes need interve...
