具有带有可切换电极的抓紧器和勒除器的电外科系统
摘要：
电外科系统包括抓紧器和勒除器，抓紧器和勒除器各包括电极。抓紧器包括第一电极，其可附接至能量源的第一输出。勒除器包括第二电极，其可附接至该能量源的第二输出。在第一电极和第二电极耦接至该能量源时，抓紧器和勒除器作为双极电外科系统工作。通过以抓紧器的钳爪抓紧组织，勒除器上的电极和抓紧器上的电极之间的电流路径相对短路，并因此该系统类似于单极电外科系统工作。因此，所施加的能量能够汇聚至小区域，最小化了对周围组织的损伤。另外，通过双极电外科系统能够容易地施加适于使所去除组织的柄的切除部凝结的能量。
摘要（英）：

An electrosurgical system includes a grasper and a snare that each includes electrodes. The grasper includes a first electrode that is attachable to a first output of an energy supply. The snare includes a second electrode that is attachable to a second output of the energy supply. When the first and second electrodes are coupled to the energy supply, the grasper and snare operate as a bipolar electrosurgical system. By grasping the tissue with the jaws of the grasper, the current path between the electrode on the snare and the electrode on the grasper is relatively short, and thus the system operates like a bipolar electrosurgical system. Accordingly, the applied energy can be focused to a small area, minimizing damage to surrounding tissue. In addition, energy suitable for coagulating the cut portion of the stalk of the removed tissue can be readily applied with the bipolar electrosurgical system.
