摘要： An end effector assembly of a forceps includes a first jaw member with a first sealing surface and a second sealing surface; a second jaw member with a first sealing surface and a second sealing surface, the first jaw member and the second jaw member being moveable relative to each other between an open position and a closed position, the first jaw member and the second jaw member including a blade slot defined therein and extending substantially along the first jaw member and the second jaw member, the first sealing surfaces being positioned on an opposite side of the blade slot than the second sealing surfaces; and a cutting blade that reciprocates in the blade slot. When the first jaw member and the second jaw member are in the closed position, the first sealing surfaces are separated by a first gap and the second sealing surfaces are separated by a second gap, the second gap being larger than the first gap.

摘要： The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.

摘要： An electrosurgical device that can be used to remove pedunculated tissue structures such as polyps and certain uterine fibroids includes bipolar surface electrodes and a bipolar snare. The device includes a probe having a proximal end and a distal end, bipolar surface electrodes adjacent to the distal end of the probe, and a bipolar snare extending distally from the distal end of the probe and including first and second snare electrodes. The bipolar surface electrodes are separated from each other by a gap and extend over a portion of the distal end of the probe. Providing both a bipolar snare and bipolar surface electrodes advantageously reduces thermal spread from occurring (compared to the use of a monopolar snare) when using the snare to excise the tissue. The bipolar surface electrodes can be used to coagulate the point of excision.

摘要： 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.
摘要翻译：电外科系统包括每个包括电极的抓紧器和圈套。抓取器包括可连接到能量供应的第一输出的第一电极。圈套包括可连接到能源的第二输出的第二电极。当第一和第二电极耦合到能量供应时，抓紧器和圈套作为双极电外科系统工作。通过用夹具的钳口抓住组织，圈套上的电极与抓紧器上的电极之间的电流路径相对较短，因此系统像双极电外科系统一样操作。因此，所施加的能量可以聚焦到小的区域，从而最小化对周围组织的损伤。此外，可以容易地用双极电外科系统施加适于凝固切除的组织的茎的切割部分的能量。
