超声刀在腹腔镜手术中的应用

Application of harmonic scalpel in laparoscopic surgery

目的 观察超声刀在复杂的腹腔镜手术中的切割止血效果。方法 比较使用超声刀 (5 7例 )和高频电刀 (5 0例 )行腹腔镜手术的临床效果。结果 所有病例均在腹腔镜下完成手术 ,无 1例中转开腹 ,无术中及术后并发症或大出血发生。使用超声刀的平均手术时间 ,平均出血量均少于使用高频电刀者。结论 超声刀具有精确切割 ,凝血可控制的功能 ,损伤小 ,提高了腹腔镜手术的安全性及微创水平 ,是一种重要和有用的腹腔镜手术设备。

Objective To evaluate the dissection and hemostasis effects of harmonic scalpel in laparoscopic surgery. Methods The effect in patients underwent laparoscopic surgery with harmonic scalpel or with high frequency electricity scalpel was compared. Results All the operations were done by laparoscopy.No complications or massive blood loss occurred during and after operation.The average operation time ,blood loss of operation with harmonic scalpel were less than that with high frequency electricity scalpel. Conclusions Harmonic scalpel has precise cutting , controlled coagulation, and less tissue injury,it can increase the safety and microsurgery techinque of laparoscopic surgery.It is a very important equipmeat and useful for laparoscopic surgery .
