The harmonic scalpel is an ultrasonically activated surgical instrument for tissue dissection. Despite its expanding surgical applications, there are no reports about associated complications.
A 35-year-old woman sustained injury to the sigmoid colon from the use of the harmonic scalpel during laparoscopic lysis of pelvic adhesions. The injury was identified and repaired laparoscopically in a primary fashion with no subsequent sequelae.
Acoustic energy coupling and overheating of the laparosonic blade extender sheath occur with bending of the instrument. This can happen with steering of the blade extender during laparoscopic surgery and may increase the exposure risk of adjacent tissues to injury.
超声刀是一种用于组织切割的超声激活手术器械。尽管其手术应用不断扩展，但尚无关于相关并发症的报道。
一名35岁女性在腹腔镜下松解盆腔粘连时使用超声刀导致乙状结肠损伤。该损伤在腹腔镜下被识别并一期修复，随后未出现后遗症。
器械弯曲时会发生声能耦合和腹腔镜超声刀延长鞘过热。这可能在腹腔镜手术中刀片延长器转向时发生，并可能增加相邻组织受伤的暴露风险。
