Abstract
The utility model discloses an artificial bone, and relates to the technical field of inorganic material surface modification. The artificial bone comprises a base portion and an end portion, and a shockproof layer is arranged in the base portion and the end portion. The surface of the end portion is provided with a wearing layer, and the surface of the base portion is provided with a composite membrane which is 40-200nm in thickness. The artificial bone is reasonable in structure, and high in practicality. The shockproof layer buffers external forces, and effectively avoids possibility of re-injury. The wearing layer is wear resistant and corrosion resistant, and the composite membrane is excellent in anticoagulation performance. The biologic compatibility and corrosion resisting performance of the base portion are improved, and the thickness of the composite membrane ensures better effect.
Description
Technical field
This utility model relates to inorganic material surface modification technology field, the particularly modification technology of artificial bone's head material.
Background technology
Along with the further raising of people's living standard and the progress of medical skill, be implanted into artificial organ and be widely used in clinical treatment, as first-class in artificial joint, artificial heart, intravascular stent, artificial bone.These embedded material great majority are made by RESEARCH OF PYROCARBON, high polymer etc.Due to the shortcoming of such Biocompatibility energy, when contacting with blood electricity or body fluid, they will produce a series of biochemical reactions, and cause platelet adhesion to form thrombosis, or cause the biological respinses such as sensitization, toxicity, inflammation, produce some physiological side effects.For example: Granted publication number is CN101024096, Granted publication day is on 08 29th, 2007, patent name is artificial organ of a kind of surface modification treatment and preparation method thereof, the artificial organ bio-compatible performance of this patent, anti-wear performance are poor, and complex process poor practicability, can not meet the requirement of modern people to living standard far away.
Summary of the invention
The purpose of this utility model is to provide a kind of artificial bone through surface modification treatment with strong biocompatibility, anticoagulation function, wear-resistant function, to overcome the deficiencies in the prior art.
To achieve these goals, this utility model is to realize by the following technical solutions:
A kind of artificial bone, comprises matrix part and end, in described matrix part, is provided with shakeproof layer, and described bone ends surface is provided with wearing layer, and described matrix part surface is provided with composite membrane, and described composite membrane thickness is 40-200nm.
Preferably, described wearing layer is titanic oxide material.
Preferably, described praseodymium element and titanium dioxide mass ratio are 1:100-155.
Preferably, described shakeproof layer is sponge material.
The beneficial effects of the utility model are: rational in infrastructure, practical, shakeproof layer has the effect of buffering external strength, effectively evade again injured danger, wearing layer has wear-resisting, corrosion resistant feature, composite membrane has very strong anticoagulation function, and further strengthen biocompatibility and the decay resistance of matrix, the rational thickness of composite membrane can have better effect, preferred composite films thickness is 40-200nm, improved anticoagulation function, biocompatibility, the performance such as corrosion-resistant, wearing layer is titanic oxide material, good biocompatibility, easily granulation promoting, praseodymium element and titanium dioxide mass ratio are 1:100-155, make the bond properties of composite membrane, evenly performance is improved greatly, shakeproof layer is sponge material, density is little, damping performance excellence.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of artificial bone described in the utility model.
Wherein: 1-artificial bone cephalic par, 2-shakeproof layer, 3-composite membrane, the artificial bone matrix part of 4-, 5-wearing layer.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth this utility model.
As shown in Figure 1, a kind of artificial bone, comprises matrix part 4 and end 1, and described inside bone is provided with shakeproof layer 2, and described bone ends surface is provided with wearing layer 5, and described matrix part surface is provided with composite membrane 3, and described composite membrane 3 thickness are 40-200nm.
In the present embodiment, artificial inside bone is provided with shakeproof layer 2, there is the effect of buffering external strength, effectively evade again injured danger, artificial bone's cephalic par 1 is provided with wearing layer 5, has wear-resisting, corrosion resistant feature, artificial bone matrix part 4 is provided with composite membrane 3, has very strong anticoagulation function, and further strengthens biocompatibility and the decay resistance of matrix part 4.
It should be noted that multiple wearing layer 5 is titanic oxide material, good biocompatibility, easily granulation promoting, the rational thickness of composite membrane 3 can have better effect, preferred composite films thickness is 40-200nm, improved anticoagulation function, biocompatibility, the performance such as corrosion-resistant, zinc oxide material has anticoagulant functions, nontoxic, good biocompatibility, zinc oxide has antibacterial in addition, sterilizing function, can reduce antibacterial infection and inflammatory reaction that embedded material causes, praseodymium is rare earth element, nontoxic anticoagulation function is strong, the mass ratio of zinc oxide and praseodymium is 1:100-155, make the bond properties of composite membrane, evenly performance is improved greatly, the vibration-absorptive material of shakeproof layer 2 is sponge in addition, density is little, damping performance excellence.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of this utility model spirit and scope; this utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed this utility model, and the claimed scope of this utility model is defined by appending claims and equivalent thereof
