Fusion device ontology of the present invention is provided with the first development needle in front end and right end junction, connects in rear end and right end
The place of connecing is provided with the second development needle, and the first development needle and the second development needle are parallel to each other.
Compared with the prior art, the present invention has the following beneficial effects: the upper and lower surfaces of 1, fusion device ontology are equipped with pawl
The anti-slop serrations of shape, anti-slop serrations can increase the contact area of dypass waist Invasive lumbar fusion device and lumbar intervertebral, increase between dypass lumbar vertebrae
Frictional force between fusion device and lumbar vertebra makes dypass waist Invasive lumbar fusion device fixing-stable, prevents dypass waist Invasive lumbar fusion device
It is skidded off from lumbar vertebra, the stability after increasing implantation achievees the purpose that fusion；2, fusion device ontology is equipped with up and down
Bone grafting hole, cut cancellous bone from anterior superior iliac spine, autologous bone fragment filled at fusion device inner cavity and panelling, bone grafting hole can be inserted
Bone grafting, bone grafting area is big, improves fusion speed, enhancing syncretizing effect；3, the height of fusion device ontology front end is greater than the height of rear end
Degree, is consistent with the physiology lordosis of lumbar vertebrae, is conducive to restore lumbar vertebrae physiological curve, reduces the generation of neighbouring section intervertebral disc degeneration
Rate；4, the lateral surface of the left end of fusion device ontology is in outer convex globoidal, and when the lateral surface of right end is in inner concave arc surface, left end lateral surface is
Dissection shape design similar with adjacent vertebral leading edge, is conducive to post-operative fusion；5, auxiliary positioning hole is located at close to fusion device ontology
When the side of left end, bone grafting area is big, and fusion rate is high.
