The fixing lug boss 520 of mounting blocks 500 is stretched into the second mounting hole 411 on lockplate 410, fusion plate 510 covers
The second mounting hole of lid 411, and the top and bottom of leading truck 300 is respectively penetrated two backwards to setting two lock brackets 400
In second mounting hole 411 of lockplate 410, and fixing lug boss 520 is set to penetrate in the first mounting hole 330 in lock bracket 400, the
The inwall of two mounting holes 411 is engaged with the outer wall of leading truck 300 by guide groove 412 with guide pad 350.Then will assemble
Mounting blocks 500, lock bracket 400 and leading truck 300 130 be put into from opening in fixed mount 100, make the axis of guide of adjusting rod 200
210 stretch into fixed mount 100 from the second through hole 120, and it is convex to sequentially pass through 320, two fixations of fourth hole on leading truck 300
Third through-hole 310 on platform 520 and leading truck 300, the 3D printing Invasive lumbar fusion device 10 assembled.
Then the 3D printing Invasive lumbar fusion device 10 assembled is assembled fixed in host, Figure 14 is referred to, by outer
Portion's instrument rotates drive shaft 220, and the end face and the end face of leading truck 300 for making drive shaft 220 lean, and drive leading truck 300
Move in the horizontal direction, because leading truck 300 is engaged with lock bracket 400 by guide groove 412 with guide pad 350, under being located at
Guide groove 412 and the guide pad 350 of side are inclined upwardly setting along close to the direction of first through hole 110, guiding above
Groove 412 and pilot hole tilt down setting along the direction close to first through hole 110, refer to Figure 15, thus lock bracket 400 and
Mounting blocks 500 produce the movement of vertical direction, so that fusion plate 510 covers opening 130, locking boss 420 protrudes from fixation
Frame 100, so that the tip 421 of locking boss 420 is embedded in the centrum of host, so as to which the fusion device 10 be fixed, Ke Yiyou
Effect avoids fusion device 10 from producing shifting phenomena.
By above-mentioned 3D printing Invasive lumbar fusion device 10, fusion device 10 is enabled to be put in the case where not scratching adjacent vertebral
In fixed position, and fusion device 10 can be effectively fixed between centrum.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
