Cardiovascular stent cutting technique by fiber laser

  • 摘要: 采用光纤激光器对血管支架进行了激光切割工艺研究,通过实验获得了聚焦透镜焦距及焦点位置、输出功率、切割速度、脉冲频率、脉冲宽度、辅助气体种类及压强等工艺参数对切缝宽度和缝面质量的影响规律。结果表明:缝宽随输出功率、频率、脉宽及辅助氧压的增大而增加,随着切割速度的增加而减小。在实验的基础上找出了血管支架切割的最佳工艺参数,在316LVM不锈钢细管上(管壁厚度为0.12mm,直径为2mm)获得了切缝均匀,缝宽小于20m网状结构的血管支架。
    Abstract: The technical study of laser cutting for cardiovascular stents was fulfilled. It is a typical application of laser micro-fabrication. The discipline of influence of the technological parameters (including the focal length of lens, focus position, laser power, cutting speed, pulse frequency, pulse width and assist gas pressure) on the quality of the cardiovascular stents were obtained with the most advanced fiber laser in the world. The results show that the kerf width increases with the increase of laser power, pulse frequency, pulse width and assist gas pressure, but decreases with the increase of cutting speed. The optimal technological parameters for cutting cardiovascular stents with laser were acquired on the base of the experiment. Stents whose kerf width is less than 20m were cut after a lot of experiments.
