为了探讨Nd:YAG激光肝部分切除的最佳功率,我们在原来动物实验及临床应用的基础上,进一步研究了不同功率Nd:YAG激光兔肝部分切除的切割,止血效应和组织损伤,实验结果显示;激光输出功率越高时,切割速度越快,止血效果越好。但是功率大于60W时,因光纤末端易熔或击穿已经凝固的大血管,切割和止血效果反而降低。功率低于15W时则不能完成切割。Nd:YAG激光能够凝固直径为3mm的肝静脉、2mm
In order to explore the optimal power of partial hepatectomy with Nd:YAG laser, we further studied the effects of partial hepatectomy, hemostasis, and tissue damage on rabbits with different powers of Nd:YAG laser based on the original animal experiments and clinical applications. Display; The higher the laser output power, the faster the cutting speed and the better the hemostatic effect. However, when the power is more than 60W, the cutting and hemostasis are reduced because the end of the fiber is apt to melt or break through the solidified large blood vessels. When the power is less than 15W, the cutting cannot be completed. Nd:YAG laser solidifies hepatic vein with 3mm diameter, 2mm
