双极凝结探针和勒除器
摘要：
一种电外科设备(100)，其能够用于移除带蒂组织结构，诸如息肉和某些子宫肌瘤，该电外科设备包括双极表面电极(122、124)和双极勒除器(110)。该设备包括：探针(130)，其具有近端(134)和远端(132)；双极表面电极(122、124)，其靠近探针的远端；以及双极勒除器(110)，其从探针的远端向远侧延伸并包括第一和第二勒除器电极(112、114)。双极表面电极(122、124)彼此间隔一间隙并在探针远端的一部分上延伸。提供双极勒除器和双极表面电极二者有利地减少了在使用勒除器来切除组织时的热扩散发生(对比于单极勒除器的使用)。双极表面电极能够用于凝结切除点。
摘要（英）：

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.
