精细解剖电外科装置
摘要：
本发明涉及精细解剖电外科装置。至少一些示例性实施方案是这样的电外科棒，所述电外科棒包括：细长轴，其界定把手端和远端；第一排放孔，其位于所述细长轴的远端上；由导电材料形成的第一有源电极，其布置在所述细长轴的远端上，所述第一有源电极具有边缘特征部；由导电材料形成的第一返回电极，其布置为基本上与所述第一有源电极相距恒定距离；以及抽吸孔，其位于所述细长轴的远端上并且流体耦合到第二流体导管。
摘要（英）：

An electrosurgical wand. At least some of the illustrative embodiments are electrosurgical wands including an elongate shaft that defines a handle end and a distal end, a first discharge aperture on the distal end of the elongate shaft, a first active electrode of conductive material disposed on the distal end of the elongate shaft, the first active electrode has an edge feature, a first return electrode of conductive material disposed a substantially constant distance from the first active electrode, and an aspiration aperture on the distal end of the elongate shaft fluidly coupled to a second fluid conduit.
