Abstract
The utility model discloses a titanium plate fixing device, which is used for the treatment of cervical diseases, spondylolisthesis and cervical fusion. The fusing device of the internal fixing device is partly tower-shaped and hollow with big diameter. A wing-shaped connecting head is connected with a circular connecting hole with a clamping groove in the center of the titanium plate at the side with bigger diameter. And with 90 degrees rotation of the connecting head, the fuser part and the titanium plate are locked tightly as a whole. The physical curve of a neck vertebrae and the vertebrae interspace height of degenerative neck vertebrae can be recovered with long-term maintaining, improving fusion rate of vertebrae interspace and fixing degenerative unstable neck vertebrae firmly.
Description
One, affiliated technical field:
This utility model relates to a kind of inner fixing device that is used for treatment of cervical spondylopathy, especially relates to the internal fixator for cervical vertebrae that is used for cervical vertebra degenerative disease, the slight slippage of cervical vertebra.
Two, background technology
At present, during cervical vertebra degeneration's operative treatment, preceding road inner fixer has internal fixation such as titanium plate, Invasive lumbar fusion device, fusion device is implanted intervertebral space and is reached the purpose that merges between vertebral body, but fusion device deviates from, and instant fixation is poor, especially the stretch-proof effect is poor, and the disc height that the later stage struts is lost.The titanium plate is fixed with loosening, the fracture of screw, and the titanium plate is loosening, and anti-turning effort is poor on the mechanics.
Three, summary of the invention:
Be fixed on the weakness on the mechanics and cause corresponding consequence in order to overcome simple fusion device or titanium plate, this utility model provides a kind of internal fixator for cervical vertebrae, this holder has not only overcome the weakness on the simple holder mechanics, simultaneously with on fusion device and the titanium plate mechanics excellent, shortcoming is complementary, reaches more firm fixing.
This utility model solves the new technical scheme that adopts of its technical problem: the titanium board is divided into " worker " font, and the edge arc also has physiologic radian, and the center is the connecting hole of band draw-in groove plate.Fusion device is to have 2 big main 6 ° of gradient rectangles of tower shape that merge hole and several auxilliary fusion holes that screw thread is arranged on the wall, and the wing union joint is arranged at the bottom.After fusion device is implanted intervertebral space, the connecting hole of titanium plate and fusion device connecting hole tabling, rotation fusion device union joint makes the firm locking of joint make the main hole of merging be positioned at intervertebral space adjacent vertebral bodies opposite face simultaneously for 90 °, and bone grafting is easily grown in the fusion device.The titanium plate is screwed in adjacent vertebral bodies, can keep fusion device to strut height, reaches the optimal fixation effect.
The beneficial effects of the utility model are, can recover cervical curvature, strut disc height and long term maintenance after the regression, improve the intervertebral space fusion rate, fixedly secure the cervical vertebra of regression, unstability.
Four, description of drawings
Engaging drawings and Examples below further specifies this utility model: Fig. 1. be structural representation Fig. 2 of the present utility model. be partial enlarged drawing Fig. 3 of fusion device in this utility model. and this utility model titanium plate structure sketch map
Five, the specific embodiment: fusion device part among Fig. 1, screw-in is removed the adjacent vertebral bodies gap behind the vertebral pulp, titanium plate connecting hole 6 among Fig. 3 is connected with fusion device wing union joint 5 involutory back embeddings among Fig. 1, again with union joint 5 half-twists, make connecting hole draw-in groove plate 7 lockings among itself and Fig. 3, again screw among Fig. 18 is connected with screw hole 9 among Fig. 3, makes whole holder be fixed on adjacent vertebral bodies.
Claims (3)
1. pure titanium inner fixer of cervical vertebra, fusion device has 6 ° of gradients for the tower shape, symmetrical 2 main hole and several auxilliary holes of merging of merging are arranged, the titanium slab integral has physiologic radian, it is fixing that upper and lower side has 4 screw holes to match with screw, it is characterized in that: there is circular connecting hole at titanium plate portion center, and the draw-in groove plate is arranged in the hole, fusion device part afterbody has the wing union joint, is connected with the titanium plate.
2. cervical vertebra fusion-titanium board binding according to claim 1 is characterized in that: described titanium plate is that the edge is arcual " worker " font titanium plate, and there is the circular connecting hole of band draw-in groove plate at the center.
3. cervical vertebra fusion-titanium board binding according to claim 1 is characterized in that: described fusion device has 6 ° of radians, and there is the wing union joint on the base.
