| titleOfInvention | A kind of high toughness tissue engineering vascular stent and preparation method thereof |
| abstract | The invention belongs to the technical field of artificial tissue engineering stents, and discloses a high-toughness tissue engineering blood vessel stent, which is prepared by blending PCL, PLA and TPU according to the mass ratio of (7-9):(1-3):(1-2). made of bubbles. In the tissue engineering vascular stent, PCL and PLA participate in foaming, while TPU does not participate in foaming or is slightly foamed. TPU generates a micro-sized particle structure inside the material. The micro-particles can be used as cross-linking points to effectively improve the toughness and elasticity of the material. The modulus can reach more than 3MPa, and the elongation at break can reach more than 400%. The invention also discloses a preparation method of the high toughness tissue engineering blood vessel stent, which does not need to introduce additional solvent, has the characteristics of non-toxic and harmless, and has good mechanical properties. |
