摘要

血管支架在治疗动脉狭窄和其他血管相关疾病方面有很多应用。临床应用的理想血管支架应具有符合血管变形协调要求的径向支撑和轴向弯曲机械性能。植入人体的血管支架所用材料应具有相应的生物相容性,以确保支架不会在血液中引起凝血、溶血等反应。本研究采用熔融长丝制造技术,以热塑性聚氨酯(TPU)为材料,制造了四种类型的血管支架,包括内六角、箭头、四边形和外六角。通过评估边缘宽度和壁厚对径向支撑和轴向弯曲性能的影响,发现在相同条件下,内六边形支架的径向支撑和轴向弯曲性能最好。基于三维打印技术的血管支架设计与制造在个性化定制血管修复治疗中具有广阔的应用前景。

Mechanical Property of Thermoplastic Polyurethane Vascular Stents Fabricated by Fused Filament Fabrication.

Vascular stents have many applications in treating arterial stenosis and other vascular-related diseases. The ideal vascular stent for clinical application should have radial support and axial bending mechanical properties that meet the requirements of vascular deformation coordination. The materials used for vascular stents implanted in the human body should have corresponding biocompatibility to ensure that the stents do not cause coagulation, hemolysis, and other reactions in the blood. This study fabricated four types of vascular stents, including inner hexagon, arrowhead, quadrilateral, and outer hexagonal, using fused filament fabrication technology and thermoplastic polyurethane (TPU) as materials. By evaluating the effects of edge width and wall thickness on the radial support and axial bending performance, it was found that the inner hexagonal stent exhibited the best radial support and axial bending performance under the same conditions. The design and fabrication of vascular stents based on 3D printing technology have promising application prospects in personalized customized vascular repair therapy.
