Detailed description of the invention
A kind of ne-leakage baffle-type vertebral body shaper as shown in Fig. 1 ~ 7, include apparatus portion 1, apparatus portion is connected with repair and implants rod 2, its unusual part is: apparatus portion 1 of the present invention includes stay pipe 3, and the front end of stay pipe 3 is connected with directing assembly by push-rod assembly.Meanwhile, the rear end of stay pipe 3 is provided with limit assembly.Specifically, directing assembly includes conduit 5, is fixed with baffle plate 4 in the front end of conduit 5.Further, the both sides of conduit 5 are provided with outlet 7, and conduit 5 inwall is provided with guide rail 6.Certainly, baffle plate 4 height 16 is less than the external diameter of conduit 5, exits from conduit 5 to repair to implant after rod 2 is repaired.
With regard to the present invention one preferably embodiment, use for the ease of being placed in pedicle of vertebral arch and preventing from sinking, the front end of the stay pipe 3 adopted is distributed with main taper configurations 13, and be distributed with positive stop lug boss 14 after this main taper configurations 13, the tail end of stay pipe 3 is distributed with platform 15.Meanwhile, in order to easy-to-use, carry out effectively correct implantation, the front end of the reparation implantation rod 2 of employing is provided with main inclined plane 17.Corresponding with it, the rear end that rod 2 is implanted in this reparation is distributed with secondary inclined-plane 18 simultaneously.Further, repair excellent 2 both sides of implantation and be distributed with groove 12.Like this, groove 12 and guide rail can be allowed to adapt to, prevent reparation implantation rod 2 from inserting in process and overturn.
Further, effectively spacing in order to carry out former entirety, the tail end of conduit 5 is provided with main thread 19, and main thread 19 is connected with gag lever post 8.Meanwhile, gag lever post 8 inwall is distributed with from screw thread 20.Like this, gag lever post 8 can at main thread 19 adjusting position, and gag lever post 8 can be spacing after contacting with the platform 15 of stay pipe 3 tail end, prevents a kind of ne-leakage baffle-type vertebral body shaper from entering vertebral body excessively dark, to ensure safety.
Again further, in order to improve repairing the propelling movement stability implanting rod, the push rod of employing includes tack push rod 10 and conical head push rod 11.Specifically, the front end of the tack push rod 10 of employing is distributed with plane 21, is distributed with main groove 23 in the both sides of tack push rod 10.Meanwhile, described main groove 23 contacts with guide rail 6, rod 2 is implanted in reparation deliver to outlet 7 place.Corresponding with it, the front end of the conical head push rod 11 of employing is secondary taper configurations 22, is distributed with secondary groove 24 in the both sides of conical head push rod 11.Like this, can adapt to guide rail 6 equally, enter vertebral body to be extruded outside conduit 5 by the reparation implantation rod 2 being positioned at outlet 7 place.Like this, when reality uses, reparation is implanted rod and 2 is shifted outlet 7 place onto along guide rail by tack push rod 10, then change by conical head push rod 11 reparations implanted excellent 2 extrude conduit 5 export 7 outside enter in vertebral body.
Moreover for the ease of user operation, portion is provided with handle with apparatus.Meanwhile, when reality uses, repair implant rod 2 can many pieces insert in vertebral body, keep vertebral body intensity and height, prevent postoperative vertebral height from too much losing thus ensureing curative effect.
Can be found out by above-mentioned character express, after adopting the present invention, rely on a kind of apparatus portion of ne-leakage baffle-type vertebral body shaper and repair implantation rod, effectively can carry out vertebral body bone repair.Meanwhile, repairing and implanting rod is solid, can thoroughly solve bone cement leakage problems, stops the respective risk that bone cement seepage produces.Thus, avoid occurring that long-term postoperative vertebral height is lost.Moreover the present invention constructs rationally, grasp easy, be convenient to promote the use of.
These embodiments are only the prominent examples of application technical solution of the present invention, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within the scope of protection of present invention.
