妇科肿瘤腹腔镜手术中超声刀应用技巧及副损伤防治

Application skills and injury preventions of ultrasonic scalpel in the laparoscopic surgery for gynecological tumors

超声刀是一种把电能转换为机械能的手术器械,主要工作原理是通过刀头的振荡摩擦产生热能作用在组织上,具有凝血和切割同时完成、刀头温度低、侧向热传导小、无电流刺激等特点。在妇科恶性肿瘤手术的一些关键技术操作上有独特优势,提高了腹腔镜手术的安全性和减少了术后的一些并发症。超声刀引起的输尿管或肠管的损伤,仍然按照热损伤的原则进行防治和处理。

Ultrasonic scalpel is one of the most widely-used energy equipment in the laparoscopic surgery for gynecological oncology. The principle is to transform the electric power into mechanical longitudinal movement, and through vibration and friction of the blade thermal power is produced and acted on the tissues. Ultrasonic scalpel has the function of coagulation and cutting at the same time,with the advantage of low temperature of blade, slight lateral thermal tissue damage and absence of electrical stimulation. Additionally, in laparoscopic surgery for gynecological malignant tumor, the ultrasonic scalpel is safe and can reduce postoperative complications. Treatments and preventions of the ureter or bowel damage caused by ultrasonic scalpels are still in accordance with the principles of thermal injury.
