红外激光心肌打孔规律的实验研究

Research of the Regularity of Infrared Laser's Making Holes in Myocardium

报告了CO_2激光和Er:YAG激光在心肌组织上进行打孔的实验结果。给出了三条实验曲线:输出功率为100W时,CO_2激光心肌打孔的孔深和打孔时间的关系曲线;打孔时间为0.3s时,CO_2激光心肌打孔的孔深和输出功率的关系曲线;脉冲能量为500mJ时,Er:YAG激光心肌打孔的孔深和脉冲数的关系曲线。并对实验结果进行了分析研究,为激光心肌血管重建术的临床应用提供了一个参考。

The paper reports the experimental results of CO2 laser and Er: YAG laser making holes in myocardium. It gives three experimental curves: h-t curve of CO2 laser's making hole in myocardium when power is 100 W, h-W curve of CO2 laser's making hole in myocardium when irradiating time is 0. 3 s, h-n curve of Er: YAG laser's making holes in myocardium when pulse energy is 500 mJ. It analyses the experimental results and provides a reference for clinical application of laser transmyocardial revascularization.
