本文介绍了大功率CO_2激光手术刀做半脾切除及脾破裂止血手术。用杂种狗进行实验研究。阻断脾门后,用刀头功率160～200W的激光刀,聚焦切割,焦点外激光束止血。不需向脾动脉注射肾上腺素,同样创面干燥,焦化良好。20例动物全部成活。无术后感染,无继发出血。经一年观察,杀死动物,见脾脏手术切面已有脾包膜形成。所以本研究较保留脾器官其它手术,安全可靠。有可能成功地过渡到临床应用。 This article describes the high-power CO_2 laser scalpel to do splenectomy and splenic rupture surgery. Experiment with mongrel dogs. After the spleen door is blocked, a laser knife with a power of 160 ~ 200W is used to focus and cut the laser beam outside the focus to stop bleeding. No injection of epinephrine to the splenic artery, the same wound dry, coking well. All 20 animals survived. No postoperative infection, no secondary bleeding. After a year of observation, killing animals, see spleen surgery section has spleen capsule formation. Therefore, this study more than other splenic organ preservation surgery, safe and reliable. It is possible to successfully transition to clinical application.
