Background technology
The generation of various skeletal diseases and mishap has proposed requirement to the reproducibility treatment of tissues such as skeleton, tooth, thereby has caused the research boom of researcher to medical bone renovating material.All once caused people's interest based on the metal species material of titanium alloy, the phosphate ceramics of biologically active and the bio-vitric of some bioactive ingredients, but the defective of these materials itself has determined them can not obtain purposes widely as biologically inert, can not be absorbed etc.Along with going deep into of research, the matrix material with biodegradation character causes people's attention gradually.After this material implants, soak, absorb, do not have residuals and deposit in vivo, fundamentally stopped matrix and produced pathology, thereby will produce material impact the damaged reparation of bone through body fluid.
In clinical application, new osseous tissue in the process that forms since the difference of treatment target, treatment position can not be complementary with bone renovating material well, cause bone renovating material can not satisfy the needs of clinical application fully, and expect to obtain the continuously adjustable bio-medical material of degradation rate.
Summary of the invention
The purpose of this invention is to provide a kind of nanoscale calcium phosphate continuous adjustable bio-medical calcium phosphate/collagen composite materials of finely dispersed degradation rate and preparation method thereof in the collagen matrix.
Biodegradable calcium phosphate/collagen composite materials for medical use of the present invention is made up of nano level calcium phosphate and collagen, and wherein the mass percentage content of calcium phosphate is 50%~80%, and the mass percentage content of collagen is 50%~20%.
Above-mentioned calcium phosphate comprises amorphous calcium phosphate, α phase tricalcium phosphate, β phase tricalcium phosphate, phosphatic rock, secondary calcium phosphate, phosphatic rock/α phase tricalcium phosphate composite powder, phosphatic rock/β phase tricalcium phosphate composite powder or α phase tricalcium phosphate/β phase tricalcium phosphate composite powder, and wherein phosphatic rock is fluoridated hydroxyapatite or contains carbonate phosphatic rock.Phosphatic rock/α phase tricalcium phosphate composite powder, phosphatic rock/β phase tricalcium phosphate composite powder and the α content of each phase of tricalcium phosphate/β phase tricalcium phosphate composite powder mutually are adjustable continuously in 0~100% scope.The particle size of nano level calcium phosphate is about 50nm~500nm.
Said collagen can be type i collagen that extracts from ox root tendon or the type i collagen that extracts from ox-hide.
The preparation method of Biodegradable calcium phosphate/collagen composite materials for medical use comprises the following steps:
1) be 1 * 10 with concentration
-4~10 * 10
-3The collagenolysis of g/ml stirs in the pH value is 0.5~5.0 acidic solution simultaneously, until forming milky white solution;
2) stirring evenly joins calcium phosphate powder in the collagen solution down, and the calcium phosphate of adding is 1: 1~4: 1 with the ratio of the quality of collagen;
3) stir that dropwise to add mass concentration down be 1% glutaraldehyde, the glutaraldehyde of adding is 1: 10 with the ratio of the quality of collagen;
4) continue to stir the white cotton-shaped suspended matter of appearance in solution, stop to stir and leaving standstill;
5) treating that flocculent substance all after the deposition, continues stirred solution, and dropwise drips alkaline solution, is to stop dropping at 6~7 o'clock until pH value;
6) with solution left standstill, remove supernatant after, the mould of putting into places liquid nitrogen to cool off 5min~60min, lyophilize then;
7) put into ethanol and soak repeatedly, lyophilize once more, sterilization gets final product.
Among the present invention, the acid that is used to dissolve collagen can be hydrochloric acid or acetate.The alkaline solution that drips can be NaOH, NH
4OH or KOH.Step 7) is put into ethanol and is soaked repeatedly, and general 3~6 times, each 12~24h.
By cooling time in the control liquid nitrogen, can control the pore size of composite inner.Be frozen in the dry time in order to reduce material, usually to adopt mould that the surface has a micropore for well.
The present invention has prepared Biodegradable calcium phosphate/collagen composite materials for medical use in the mode of original position complexing, this material relies on the complexing of intermolecular group carboxylate radical to form by calcium phosphate and tropocollagen molecule, on the collagen matrix, deposit calcium phosphate powder, and under the effect of glutaraldehyde, increase the mechanical strength of matrix material.On micro-scale, have the characteristics that are evenly distributed., the degradation rate of matrix material is regulated continuously with the characteristic that changes of the variation of in-phase proportion not in the powder according to the degradation rate of calcium phosphate powder, can be satisfied the requirement of different tissues engineering by the calcium phosphate powder of compound not in-phase proportion.Under the freeze drying process condition, can prepare the bone renovating material of aperture size by the calcium phosphate/collagen composite materials that this good biocompatibility, degradation rate can be regulated continuously, can be used as the degradable biological medical material and aspect medical, be used widely in 10 μ m~150 μ m and hole internal communication.
The bone renovating material that adopts method of the present invention to prepare has that calcium phosphate is evenly distributed, calcium phosphate combines with collagen closely, degradation rate characteristics such as adjustable and biocompatibility is good continuously, finally degraded fully in vivo, do not have residuals to exist, can be used as bone renovating material and be applied in bio-medical fields such as bone tissue engineer.
