Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is further described:

[0026]As shown in the accompanying drawings, a kind of expandable intervertebral fusion device is characterized in that the intervertebral fusion device consists of a front lower fusion plate 1, a left traction plate 2, an upper front fusion plate 3, a rear upper fusion plate 4, and a rear upper fusion plate. The lower fusion plate 5, the propulsion block 6, and the connecting rod 7 are composed. The front lower fusion plate 1, the front upper fusion plate 3, the rear upper fusion plate 4, and the rear lower fusion plate 5 are respectively L-shaped, and the L-shaped The front lower fusion plate 1, the front upper fusion plate 3, the rear upper fusion plate 4, and the rear lower fusion plate 5 are interlocked to form a propulsion cavity in the middle, and the connecting rod 7 is composed of an upper connecting rod, a lower connecting rod, a front connecting rod Composed of a rod...

Abstract

The invention relates to the technical field of interbody fusion cage medical instruments, in particular to an expandable interbody fusion cage. The expandable interbody fusion cage is characterized by being composed of a front lower fusion plate, a left traction plate, a front upper fusion plate, a rear upper fusion plate, a rear lower fusion plate, a propulsion block and connecting rods; the front lower fusion plate, the front upper fusion plate, the rear upper fusion plate and the rear lower fusion plate are in an L shape respectively, a propulsion cavity is formed in the middle after the L-shaped front lower fusion plate, the L-shaped front upper fusion plate, the L-shaped rear upper fusion plate and the L-shaped rear lower fusion plate are buckled, and the connecting rods comprise theupper connecting rod, the lower connecting rod, the front connecting rod and the rear connecting rod. The expandable interbody fusion cage has the advantages that by utilizing the spreading force ofthe interbody fusion cage, the height and tension of the vertebral joints are restored, compression is removed, the physiological curvature of the spine is restored, and the stability of the spine isensured 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 Organ bone fusion, an expandable 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 nee...
