Abstract
A kind of artificial skelecton, belongs to medical instruments field.Comprise artificial skelecton matrix, described artificial skelecton intrinsic silicon has the cavity of some through described artificial skelecton matrixes along its length, thus the hollow structure formed in described artificial skelecton matrix, the cavity of described artificial skelecton matrix is uniformly distributed along the radial direction of artificial skelecton matrix, distribution density is 20%-40%, and the cavity surface of described artificial skelecton matrix has the surface layer of pure titanium or titanium alloy.Artificial skelecton of the present utility model and natural skeleton are more close, are conducive to artificial skelecton and implant growth binding ability that is rear and natural skeleton.
Description
[technical field]
This utility model technical field belongs to medical instruments field, is specifically related to a kind of artificial skelecton.
[background technology]
In metallic biomaterial, titanium alloy, as important bio-medical material, has high mechanical properties, high tenacity and excellent anti-fatigue effect, is therefore long-acting or the optimal metallic biomaterial of Permanent implantation human body.
Although the elastic modelling quantity of biological titanium alloy is far below the first generation and second filial generation metallic biomaterial, but it is still higher compared with natural skeleton, if the elastic modelling quantity of biological titanium alloy therefore can be reduced further, can make biological titanium alloy and natural skeleton more close, thus meet clinical medical further.Now widely used foam metal material hole mostly is monomer closing structure, and each hole cannot be through, is unfavorable for that artificial skelecton is combined with the growth of natural skeleton, and metal material also exists the problem entering the corrosion of body rear surface for a long time in addition.
[summary of the invention]
For the problems referred to above, this utility model provides a kind of artificial skelecton, the problem that its artificial skelecton inner pore that simultaneously can solve the manufacture of existing foam metal material cannot be through and the etching problem of metal surface.
This utility model is achieved in that
A kind of artificial skelecton, comprise artificial skelecton matrix, it is characterized in that: described artificial skelecton intrinsic silicon has the cavity of some through described artificial skelecton matrixes along its length, thus the hollow structure formed in described artificial skelecton matrix, the cavity of described artificial skelecton matrix is uniformly distributed along the radial direction of artificial skelecton matrix, distribution density is 20%-40%, and the cavity surface of described artificial skelecton matrix has the surface layer of pure titanium or titanium alloy.
The facing surface of described pure titanium or titanium alloy has tricalcium phosphate coating, or has the thick differential arc oxidation coating of 15nm.
The cavity of described some artificial skelecton matrixes is filled with micropore communicating together and crack.
The cavity of described artificial skelecton matrix becomes regular hexagon structure.
The cavity of described artificial skelecton matrix is built-in with medicine.
Technique effect of the present utility model is, there is in artificial skelecton matrix the hollow structure be connected with each other, more close with natural skeleton, be conducive to the infiltration in artificial skelecton of body fluid or bone marrow and flowing, coating prevents metal erosion on the one hand, the generation of hydroxy phosphorous stone lime stone can be induced simultaneously, be more conducive to artificial skelecton and implant growth binding ability that is rear and natural skeleton.
