This utility model realizes like this, a kind of cervical vertebral fusion cage, comprise a upper surface, a lower surface and connect the column of described upper surface and lower surface, described column inner hollow forms filler opening through before and after, described column comprises column upper end, column lower end, column left side wall and column right side wall, described column upper end is by described column left side wall, column right side wall is connected with described column lower end, on the outer surface of described column left side wall and the outer surface of described column right side wall, level is provided with the first groove and the second groove successively respectively.
Further, described first groove is circular groove, and described second groove is square groove.
Further, described upper surface and described lower surface are respectively equipped with an anti-skid structure.
Further, former and later two sides on the right side of former and later two sides of described column left side wall and described column are respectively equipped with the projection of multiple outside thorn-like.
Further, described prominent number is 9-12.
Further, the material of described cervical vertebral fusion cage is apatite/PK composite.
The beneficial effects of the utility model are: a kind of cervical vertebral fusion cage that this utility model provides, it comprises a upper surface, the column of a lower surface and connection upper surface and lower surface, column inner hollow forms filler opening through before and after, column comprises column upper end, column lower end, column left side wall and column right side wall, column upper end is by column left side wall, column right side wall is connected with column lower end, on the outer surface of column left side wall and the outer surface of column right side wall, level is provided with the first groove and the second groove successively respectively, the biocompatibility of this Invasive lumbar fusion device, good mechanical performance, there is good osteogenic, osteoconductive potential, fusion device can maintain enough mechanical strengths, biological activity is high, fast biology fusion faculty, promote its rapid fusion, shorten the time required for Rehabilitation, simultaneously, when Invasive lumbar fusion device is between implantation vertebra, by tool holding at the first groove and the second groove, be easy to cervical vertebral fusion cage to send in cervical vertebral space, and instrument can fully contact with cervical vertebral fusion cage when ensureing to implant, uniform force.
In addition, Invasive lumbar fusion device adopts apatite/PK composite to be more evenly distributed between implantable bone and fusion device by stress, and stress shielding is little; Stress can be transferred on implantable bone gradually, has better fusion rate.And along with time lengthening.And composite can X-ray thoroughly, CT, MRI does not produce artifact, can meet the needs of routine examination.
In addition, apatite/PK composite bone repairing material is combined with osseous tissue closely, interface is without bone resorption, all patients can obtain Bony union in 6 months, meanwhile, nano-apatite can carry out enhancing and toughness reinforcing to PK, increases the bond strength of apatite/PK composite bone repairing material, osseous tissue interface, reduce fine motion and vertical displacement, the initial stability of implant can be guaranteed.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the overall schematic of the cervical vertebral fusion cage that this utility model one embodiment provides.
Fig. 2 is the structural representation of its sidewall of cervical vertebral fusion cage that this utility model one embodiment provides.
Fig. 3 is the structural representation of the cervical vertebral fusion cage upper surface that this utility model one embodiment provides.
Detailed description of the invention
The technical problem solved to make this utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with drawings and Examples, are further elaborated to this utility model.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As Fig. 1, shown in Fig. 2 and Fig. 3, this utility model embodiment provides a kind of cervical vertebral fusion cage, comprise a upper surface 1, the column 3 of a lower surface 2 and connection upper surface 1 and lower surface 2, column 3 inner hollow forms filler opening 31 through before and after, column 3 comprises column upper end 32, column lower end 33, column left side wall 34 and column right side wall 35, column upper end 32 is by column left side wall 34, column right side wall 35 is connected with column lower end 33, on the outer surface of column left side wall 34 and the outer surface of column right side wall 35, level is provided with the first groove 36 and the second groove 37 successively respectively, because the first groove 36 and the second groove 37 are horizontally disposed successively, like this, when Invasive lumbar fusion device is between implantation vertebra, the first groove 36 and the second groove 37 place is clamped in respectively by instrument, cervical vertebral fusion cage can be easy to send in cervical vertebral space, and instrument can fully contact with cervical vertebral fusion cage when ensureing to implant, uniform force.
