Background technology
Artificial spine intervertebral disk prosthesis conventional on the market is at present various informative, but all following shortcomings of ubiquity: is that product structure is loaded down with trivial details, select size comparatively unification, for the individuality that some vertebral bodys are less, after implanting, prosthese can not recover and maintain the height of intervertebral space well, thus causes intervertebral space wide, is difficult to keep segmental stabilization, cause Minor articulus activity to be lost, finally cause atypical ossified; Two is that product resisting fatigue and wear resistance are poor, and fatigue fracture, fatigue wear cause prosthese easily to produce wear particle, and wearing and tearing particle can cause aseptic bone absorption, causes prosthetic replacement failure, postoperative generation complication; Three are most products is all-metal supporting structure, postoperative prosthese only plays stability maintenance effect, and shock-absorbing function cannot be realized, and its high-quality high-elastic mechanical property and raw bone histocompatibility extreme difference, there is stress-shielding effect, destroy the body biomechanics regularity of distribution, very easily cause prosthese to subside risk.
Through looking into, the existing patent No. is the Chinese utility model patent " a kind of novel artificial lumbar disc prostheses " of CN200920035797.3, it is characterized in that the structure of artificial lumbar disc prostheses is an overall structure, by upper and lower soleplate, elastic core, elastic fiber bundle, polymer gasket forms; The shape of its three-dimensional is consistent with the shape of people's lumbar intervertebral disc, and it is configured to elastic fiber bundle and is woven into net, this net content elastic core through a circle anchor point of upper and lower soleplate punching, and this net four periderm polymer gasket wraps up.The upper and lower soleplate of this prosthese and middle spring nucleome adopt elastic fiber bundle to be woven by basketry to form, although structurally also can cushioning effect be played, but manufacture and comparatively bother, need perforate on upper and lower soleplate, and other spraying hydroxyapatite coating is also wanted in the surface of upper and lower soleplate, to increase biological stability, make cost also higher.
Summary of the invention
Technical problem to be solved in the utility model provides for the above-mentioned state of the art artificial spine intervertebral disk prosthesis that a kind of structure is simple, easily manufactured, can adapt to Different Individual demand, can closer to the biomechanical property of the true intervertebral disc of human body, and non-structure wearing and tearing.
This utility model solves the problems of the technologies described above adopted technical scheme: a kind of artificial spine intervertebral disk prosthesis, comprise upper head plate, bottom plate and central. set fit, it is characterized in that: described central. set zoarium is some layers negative poisson ' s ratio cellular construction composition from outside to inside, and the quality of cellular construction and Young's modulus successively reduce from outside to inside successively, between the fit and upper head plate of central. set, bottom plate, adopt 3D printing technique integrated molding.
As improvement, the negative poisson ' s ratio cellular construction of described central. set zoarium is more than three layers or three layers, and the wall thickness of every layer unit structure is 0.1-2.0mm.
As improvement, the upper surface of described upper head plate and the lower surface of bottom plate are equipped with the protruding sour jujube of being convenient to insert human vertebrae.
As improvement, the thickness of described upper head plate, bottom plate is between 0.6 ~ 1mm.
Improve, the rough surface of described upper head plate, bottom plate is formed with micro hole structure, and porosity is 20% ~ 60% again.
Improve, described central. set is fit selects the metal of human implantable or nonmetallic materials to make with upper head plate, bottom plate again.
Improve, described central. set is fit selects titanium alloy to make with upper head plate, bottom plate again.
Further improvement, adopts selective laser smelting technology one-body molded between the fit and upper head plate of described central. set, bottom plate.
Finally, described negative poisson ' s ratio cellular construction is indent hexagon circumferentially arrangement architecture, and in indent hexagon, upper and lower two ends cross rib plate length is identical, and middle four cant timber length are identical, and cross rib plate and cant timber angle are at 30 ° ~ 60 °.
Compared with prior art, the utility model has the advantage of: central. set zoarium is negative poisson ' s ratio cellular construction, and cellular construction quality from outside to inside and elastic modelling quantity progressively reduce, make this structure and the original intervertebral disc biomechanical property of human body closer to, avoid stress-shielding effect, effectively reduce the foreign body sensation of human body; Central. set is fit adopts laser 3D printing technique integrated molding with upper and lower end plate, there is not the situation of wearing and tearing of moving each other between structural member, effectively avoid the risk causing inflammation because of wear particle, and the integrated molding of the sour jujube of upper and lower end plate projection and the negative poisson ' s ratio cellular construction of central. set zoarium, the effect of stability maintenance damping can be played; In addition, owing to adopting the manufacture of laser 3D printing technique, the surface roughness of upper and lower end plate is higher, can form continuous print microcellular structure without the need to carrying out surface treatment, is conducive to artificial intervertebral disk Regenerated Bone and grows into characteristic, increase biological stability.This utility model structure is simple, easily manufactured, can adapt to Different Individual demand, can closer to the biomechanical property of the true intervertebral disc of human body, and non-structure wearing and tearing.
