摘要： A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.

摘要翻译：双极电外科器械在其钳口上具有对置的密封表面，用于抓住和密封容器和血管组织。内部和外部仪器构件允许密封表面的弓形运动。开放的锁箱提供具有侧向支撑的枢轴以保持侧面的对准。仪器构件上的棘轮在密封过程中在组织上保持恒定的闭合力。调整每个构件上的柄部分以提供适当的弹簧力以将密封表面保持在一起。在手术过程中，仪器可用于掌握和夹紧血管组织，并通过钳夹的组织施加双极电外科电流。在一个实施例中，密封表面是部分绝缘的，以防止当仪器钳口闭合在一起时发生短路。在另一个实施例中，密封表面可拆卸地安装在夹爪上。
