| titleOfInvention | A medical nickel-titanium alloy with high anticoagulant function without surface treatment |
| abstract | The invention relates to the field of nickel-titanium alloy materials, in particular to a medical nickel-titanium alloy with high anticoagulation function without surface treatment. In the nickel-titanium alloy, Ti accounts for 50 at.%, Cu accounts for 1.0-5.0 at.%, and the rest is Ni. The present invention also provides a method for preparing the above-mentioned medical nickel-titanium alloy with high anticoagulation function: the alloy ingot is obtained by smelting in a vacuum consumable furnace; after the alloy is forged, the temperature is kept at 1000° C. for 1 hour and water-cooled; the temperature is kept at 650-750° C. 0.5h, then under the condition that the strain rate is greater than or equal to 0.1s ‑1 , thermal deformation with a deformation amount of 75~85% is carried out, and then the temperature is kept at 550~650℃ for 0.5~1h, air-cooled, and finally the deformation amount is greater than or equal to 15%. cold deformation. The prepared nickel-titanium alloy can obtain stable superelasticity with a residual strain of 0-0.01% after 3 cycles of 15% strain training at 37 °C, and this alloy can achieve high anticoagulation without any surface treatment. blood function. The alloy can be applied to implanted medical devices such as peripheral vascular stents, non-vascular stents (esophagus, biliary tract). |
