摘要： A surgical system and associated method for sealing the passageway of a fluid-carrying vessel comprises an electrosurgical generator capable of delivering electrosurgical power, a surgical instrument connected to the electrosurgical generator and adapted to transfer electrosurgical power from the electrosurgical generator to a pair of end effectors disposed at a distal end of the instrument. The system also includes a power control circuit for controlling the delivery of energy to the vessel through the end effectors, wherein the delivery of the radio frequency energy to the vessel comprises, raising the output current to a range below 1.75 Amperes RMS and the output voltage to a range below 135 Volts RMS. Radio frequency energy is applied to the vessel for a period of time while the power is held approximately constant. The flow of radio frequency energy is terminated when the impedance of the vessel being sealed reaches a predetermined level.

摘要： An electrosurgical instrument has a movable tissue cutting mechanism and a pair of opposing jaws shaped and configured to move between a closed position for clamping and sealing tissue clamped therebetween and an open position. A first jaw has an exposed tissue sealing surface having a primary sealing surface and least one protrusion extending from the primary sealing surface for concentrating a sealing current through the at least one protrusion. A second jaw has an exposed tissue sealing surface having a primary sealing surface and at least one recess in the primary sealing surface for concentrating a sealing current through the at least one recess. The protrusion and the recess oppose one another when the jaws are in the closed position. Each of the jaws has an elongated slot for receiving a portion of the cutting mechanism. A related method is also disclosed.
摘要翻译：电外科器械具有可移动的组织切割机构和一对相对的钳夹，所述一对相对的钳夹被成形和构造成在用于夹紧和密封夹紧在其间的组织和闭合位置之间的闭合位置之间移动。第一钳口具有暴露的组织密封表面，该暴露的组织密封表面具有主密封表面和从主密封表面延伸的至少一个突出部，用于将密封电流集中通过所述至少一个突出部。第二夹爪具有暴露的组织密封表面，该表面具有主密封表面和主密封表面中的至少一个凹槽，用于将密封电流集中通过至少一个凹槽。当钳口处于闭合位置时，突起和凹口彼此相对。每个夹爪具有用于接收切割机构的一部分的细长狭槽。还公开了一种相关的方法。
