Ultrasonically activated devices (USADs) are a widely used alternative to suture ligation and clips in open and laparoscopic surgery because of their fast and easy control of bleeding without significant complications. By inducing protein denaturation and forming coaptive coagulation to seal vessels for cutting tissue, USADs result in reduced operating time, blood loss and hospital stay. Recently, various other types of vessel sealers have become available. In this article, we summarize the mechanism, efficacy and the advantages and disadvantages of USADs for appropriate use in surgery.
超声激活装置（USADs）是一种广泛应用于开放和腹腔镜手术的替代缝线结扎和夹闭的方法，因为其可以快速、轻松地控制出血，且没有明显的并发症。通过诱导蛋白质变性并形成紧密的凝固来密封切割组织的血管，USADs 可缩短手术时间、减少出血量和住院时间。最近，出现了各种其他类型的血管密封剂。本文总结了 USADs 的作用机制、疗效以及在手术中的优缺点，以帮助其合理应用。
