Specific embodiment
A kind of ne-leakage baffle-type vertebral body shaper as shown in Fig. 1~7, includes apparatus portion 1, and apparatus is connected with portion
Implantation rod 2 is repaired, its unusual part is：Apparatus portion 1 of the present invention includes support tube 3, before support tube 3
End is connected with guide assembly by push-rod assembly.Meanwhile, the rear end of support tube 3 is provided with limit assembly.Specifically, guiding group
Part includes conduit 5, and baffle plate 4 is fixedly arranged at the front end with conduit 5.Also, the both sides of conduit 5 are provided with outlet 7, the inwall of conduit 5
It is provided with guide rail 6.Certainly, the height of baffle plate 4 16 is moved back to repair after implantation rod 2 is repaired less than the external diameter of conduit 5 from conduit 5
Go out.
Just from the point of view of the preferably implementation method of the present invention one, used for the ease of being placed in pedicle of vertebral arch and preventing from sinking, use
The front end of support tube 3 is distributed with main taper configurations 13, and positive stop lug boss 14, the tail of support tube 3 are distributed with after the main taper configurations 13
End is distributed with platform 15.Meanwhile, in order to easy-to-use, effectively being properly implanted, the front end of the reparation implantation rod 2 of use sets
It is equipped with main inclined plane 17.Corresponding to be, the rear end of reparation implantation rod 2 is distributed with secondary inclined-plane 18 simultaneously.Also, repair implantation
The both sides of rod 2 are distributed with groove 12.In such manner, it is possible to allow groove 12 to be adapted to guide rail, prevent from repairing during implantation rod 2 is inserted and send out
Raw upset.
From the point of view of further, effective spacing in order to integrally be carried out to former, the tail end of conduit 5 is provided with main thread 19,
Gag lever post 8 is connected with main thread 19.Meanwhile, the inwall of gag lever post 8 is distributed with from screw thread 20.So, gag lever post 8 can be in main spiral shell
The adjusting position of line 19, gag lever post 8 can be spacing after being contacted with the platform 15 of the tail end of support tube 3, prevents a kind of ne-leakage baffle-type vertebra
Body former is too deep into centrum, to ensure safety.
From the point of view of further, in order to improve the push stability to repairing implantation rod, the push rod of use includes tack and pushes away
Bar 10 and conical head push rod 11.Specifically, the front end of the tack push rod 10 of use is distributed with plane 21, in tack push rod 10
Both sides are distributed with main groove 23.Meanwhile, the main groove 23 is contacted with guide rail 6, is delivered at outlet 7 will to repair implantation rod 2.
Corresponding to be, the front end of the conical head push rod 11 for using is secondary taper configurations 22, is distributed in the both sides of conical head push rod 11
There is secondary groove 24.So, can equally be adapted to guide rail 6, so that the reparation being located at outlet 7 implantation rod 2 is extruded outside conduit 5
Into in centrum.So, when actually used, tack push rod 10 by repair implantation rod 2 along guide rail shift onto outlet 7 at, then change by
Conical head push rod 11 will repair implantation rod 2 and extrude conduit 5 and export 7 and outer enter in centrums.
Furthermore, being operated for the ease of user, apparatus is provided with handle in portion.Meanwhile, when actually used, repair implantation
Rod 2 can many pieces insert in centrum, keep centrum intensity and height, prevent postoperative vertebral height from excessively losing so as to ensure curative effect.
By above-mentioned character express can be seen that using the present invention after, rely on a kind of ne-leakage baffle-type centrum into
The apparatus portion of shape device and reparation implantation rod, can effectively carry out centrum bone repair.Meanwhile, it is solid to repair implantation rod, can be thorough
Bottom solves bone cement leakage problems, prevents the respective risk of bone cement seepage generation.Thus, it is to avoid long-term postoperative centrum occur high
Degree is lost.Furthermore, present invention construction is reasonable, and behaviour is easy, is easy to promote the use of.
These embodiments are only the prominent examples for applying technical solution of the present invention, all to take equivalent or equivalent transformation
And the technical scheme for being formed, all fall within the scope of protection of present invention.
