    Abstract: Electrosurgical energy is used in combination with a surgical tool (12) to seal vessels and vascular tissue of a patient (13). One of the important advances of the present system is that is can effectively seal vessels of a patient (13) without leaving any foreign material in the body of the patient (13). The present system is also capable of sealing vessels as large as ten millimeters in diameter. Another advantage of the present system is that the surgeon can visually inspect the integrity of the seal. The invention works with a combination of pressure and controlled application of electrosurgical energy to achieve the desired result. A surgical tool (12) is used to grasp and apply an appropriate amount of closure force to the tissue of the patient (13). The tool is capable of conducting electrosurgical energy to the tissue concurrently with the application of the closure force. A method for sealing vessels and vascular tissue of a patient (13) includes the steps of applying pressure to the vessels and other tissues of the patient (13); applying a first level of electrosurgical power to the vessels and other tissues sufficient to melt proteins in the tissue; applying a second level of electrosurgical power to the vessels and other tissues sufficient to cause desiccation without charring; reducing the electrosurgical power substantially to zero for a length of time sufficient to allow the vessels and other tissues to cool into a new compressed form; and relieving the pressure on the tissue.

    Abstract translation: 电外科能量与外科手术工具（12）组合使用以密封患者（13）的血管和血管组织。 本系统的重要进展之一是可以有效地密封患者（13）的血管，而不会在患者体内（13）中留下任何异物。 本系统还能够密封直径达10毫米的容器。 本系统的另一个优点是外科医生可以目视检查密封的完整性。 本发明结合压力和电外科能量的受控应用来实现期望的结果。 外科手术工具（12）用于把握和施加适当量的闭合力给患者（13）的组织。 该工具能够在施加闭合力的同时对组织进行电外科能量。 用于密封患者（13）的容器和血管组织的方法包括对患者（13）的容器和其他组织施加压力的步骤; 对血管和其他组织施加足以融化组织中的蛋白质的电外科功能; 对足以引起干燥而不烧焦的血管和其他组织施加第二级电外科手术力; 将电外科手术功率基本上降低至零足以允许血管和其它组织冷却成新的压缩形式的时间长度; 并减轻对组织的压力。
