Laparoscopic vessel sealing devices have revolutionized modern laparoscopy. These devices fall into 2 major categories: advanced bipolar and ultrasonic instruments. The range of tissue effects available with these technologies is more limited than with conventional monopolar electrosurgery; however, both advanced bipolar and ultrasonic devices efficiently seal vessels (≤7-mm and ≤5-mm diameter, respectively), and most also have built-in tissue transection capabilities. These technologies have been the subject of a range of comparative studies on their relative advantages and disadvantages, and, to date, neither advanced bipolar or ultrasonic devices has been proven to be superior.
腹腔镜血管密封设备彻底改变了现代腹腔镜技术。这些设备主要分为两类：高级双极和超声仪器。与传统的单极电外科相比，这些技术提供的组织效果范围更有限；然而，高级双极和超声设备都能有效地密封血管（分别为≤7 毫米和≤5 毫米直径），并且大多数还具有内置的组织切割功能。这些技术一直是关于它们相对优缺点的一系列比较研究的主题，到目前为止，高级双极或超声设备都没有被证明具有优势。
