We have developed a laser bipolar dissector (LBD) which uses the 1,064 nm Nd:YAG wavelength. The laser emits from the inner surface of the distal 7 mm of each probe made of synthetic sapphire. With low laser power (15-25 W), the bipolar provides hemostatic cutting of larger blood vessels. Animal experiments were carried out using New Zealand white rabbits. The LBD hemostatically cut through veins up to 5 mm and arteries up to 2 mm in diameter. Rebleeding did not occur. Transection of parenchymal organs such as liver and lung was easily performed with complete hemostasis. In chronic experiments a partial hepatectomy with splenectomy and left nephrectomy was performed using the LBD alone without any ligation. Up to 3 weeks postoperatively there were no direct complications related to using the LBD. In conclusion the LBD could perform a hemostatic transection of large vessels and might have clinical application in the dissection of vascular parenchymal organs.
我们研发了一种使用1064纳米钕钇铝石榴石波长的激光双极分离器（LBD）。激光从由合成蓝宝石制成的每个探头远端7毫米的内表面发射。在低激光功率（15 - 25瓦）下，该双极分离器可对较大血管进行止血切割。使用新西兰白兔进行了动物实验。LBD能进行止血切割直径达5毫米的静脉和直径达2毫米的动脉，未发生再出血。肝和肺等实质器官的横断术可轻松进行且完全止血。在慢性实验中，仅使用LBD进行了部分肝切除术、脾切除术和左肾切除术，未进行任何结扎。术后长达3周，未出现与使用LBD直接相关的并发症。总之，LBD可对大血管进行止血横断，可能在血管实质器官的解剖中具有临床应用价值。
