| 目的：分析和评价1.32μm和1.06μmNd：YAG激光在肝脏和胃肠血管中的蒸发和凝固能力。
方法：比较自行开发的双波长高能激光手术平台1.32微米和1.06微米Nd：YAG激光对猪肝组织评价猪胃血管止血的作用。
结果：在相同参数，剂量条件下观察和测量结果。 1.32μm激光器比1.06μm激光器具有更高的汽化宽度和深度。 两次激光照射无活动性出血伤口。 在1.32μm条件下的凝结比1.06μm激光更薄，接近3mm。 对于1mm和2mm的猪血管切割，在肉眼下没有出血。 在显微镜下是可见的血管内血栓。 实验组血管栓塞长度为2-4mm，直径为2mm，对照组血栓长度为2.3-4.9mm。 血栓形成完全阻断血管。
结论:1.32μm激光蒸发能力超过1.06μm激光，可以实现2mm以下血管的止血。 |

| Objective The aim of this study was to analyze and evaluate 1.32-μm and 1.06-μm neodymium-doped
yttrium aluminum garnet (Nd:YAG) lasers for use in liver and gastroepiploic vessel vaporization and
coagulation.
Methods The effects of 1.32-μm and 1.06-μm Nd:YAG lasers were compared for gastroepiploic vessel
hemostasis in porcine liver.
Results The results were observed and measured under the same parameters and dose conditions.
The 1.32-μm laser showed greater vaporization width and depth than the 1.06-μm laser. Both lasers
controlled active bleeding. The coagulation band with the 1.32-μm laser was thinner than with the 1.06-
μm laser, at nearly 3 mm. After cutting of 1- and 2-mm porcine vessels, no grossly visible bleeding was
apparent. Intravascular thrombus was visible under the microscope. The length of vessel thrombosis in the
experimental group was 2 mm and the diameter was 2 mm; the control group exhibited thrombi as 2.3–4.9
mm in length. Thrombosis completely blocked the blood vessels.
Conclusion The 1.32-μm laser had greater vaporization capability than the 1.06-μm laser and achieved
hemostasis requirements for vessels less than 2 mm in diameter. |
