The vascular support of this kind of device fabrication comprises the hyperfine helically coiled of multilayer form metallic glass silk thread, has solved the easy hyperplasia of yielding, the perishable and vascular tissue of filament that material such as current titanium nickel memory alloy drawd and has got into support inner chamber scheduling problem to make the product gentlier, more pliable and tougher, more comfortable, the long -term use need not to change. Be applicable to the human vascular stenosis's of treatment bridging operation. Its technique belongs to new NULL field.
Description
1, technical field
It is to utilize non-crystaline amorphous metal good fluidity in the molten state and higher viscosity that non-crystaline amorphous metal intravascular stent manufactures equipment, use high pressure extrusion fast cooling shaping method, manufacture the production machine of the intravascular stent of elasticity, chemical stability and the bioaffinity with excellence.The intravascular stent of this device fabrication, the toroidal non-crystaline amorphous metal silk thread ultra-fine by multilamellar is constituted, solve that filament that the material such as existing ti-ni shape memory alloy draws is yielding, perishable and the easy hypertrophy of vascular tissue enters the problems such as rack bore, so that product gentlier, more pliable and tougher, more comfortable, life-time service without change.It is applicable to treat the bypass surgery that human vas is narrow.Its technology belongs to new material application field.
2, background technology
Amorphous metal is the new material just having walked out laboratory, is also called liquid metals or glass metal.The metal liquid of molten condition is under very fast (microsecond) cooling condition, and the atom in metal liquid is just frozen into solid with disordered state because having little time the mobile ordered lattice that formed.This solid is referred to as amorphous metal.Owing to the distribution of amorphous metal solid interior atom has the feature of liquid, (also referred to as glassy state feature) so, amorphous metal internal microstructure is totally different with the microstructure of common metal interior atoms ordered arrangement composition lattice.The change of this metal inside atom distribution, directly results in metallicity and there occurs astonishing variation.Such as, there is not lattice in amorphous metal, does not the most just have the slip between lattice and lattice defect, thus amorphous metal does not has the ductility of common metal, will not change shape.Just because of the distribution of amorphous metal interior metal atom be in microcosmic disordered state, obtain the most on the contrary quality closely, uniformly, the glassy state characteristic of amorphousness defect.This characteristic determines amorphous metal and has rigidity, toughness, elasticity and the chemical stability that common metal is difficult to match in excellence or beauty.Existing amorphous metal manufacturing technology is several metals utilizing atomic volume difference bigger, according to certain proportioning mixing, when adding heat fusing, owing to metallic atom volume difference is bigger, displacement difficulty in the liquid state, so being difficult to combination when solidification to form ordered lattice, thus obtain bulk amorphous alloys.Therefore, by the metal component being designed correctly and proportioning, it is possible under non-very fast cooling condition, the bulk amorphous alloys that atom is disordered state is obtained.When non-crystaline amorphous metal melts as liquid, there is preferable mobility and higher toughness, and when solidification, different from common metal, it does not has volumetric expansion or reduces phenomenon, be very suitable for manufacturing non-crystaline amorphous metal product by high pressure extrusion one-shot forming.Utilize the rigidity of amorphous metal excellence, toughness, elastic and extraordinary chemical stability, it is possible not only to solve deformation and etching problem that what the material technologies such as existing ti-ni shape memory alloy manufactured helical metal wire intravascular stent exists, and thinner amorphous alloy wire can be used to manufacture gentlier, more pliable and tougher intravascular stent, this novel vascular stent also has preferable bioaffinity, life-time service need not be changed, it is to avoid the misery brought to patient of again performing the operation.
Use amorphous alloy material, solve the filament problem yielding, perishable that the materials such as existing ti-ni shape memory alloy draw, it is possible to use thinner amorphous alloy wire manufactures gentlier, more pliable and tougher, service life is longer, it is not necessary to the intravascular stent of replacing.High pressure extrusion one-shot forming is used to manufacture non-crystaline amorphous metal intravascular stent product, it is possible to achieve melted non-crystaline amorphous metal liquid fast cooling shaping.Use the cooling of non-crystaline amorphous metal intravascular stent fast uniform and the isolation air in constant temp. heating oil cooling storehouse, beneficially extrusion molding, it is to avoid non-crystaline amorphous metal intravascular stent occurs oxidation reaction at high operating temperatures.Use jet mould and spiral channel mould can solve non-crystaline amorphous metal filament and be shaped to toroidal.Using double-layer spiral tube shape non-crystaline amorphous metal can strengthen intravascular stent pipe thickness and improve sealing, prevent from entering rack bore during vascular tissue's hypertrophy, block blood flows.
