混合冷等离子体束射流与大气
摘要：
本公开内容涉及一种用于在电外科应用中产生等离子体的电外科设备。该电外科设备包括设置在电外科设备的管的远端部分上的端部效应器。该端部效应器使环境空气与惰性气体混合以便增加自由基种类的产生。在本公开内容的一个方面中，该端部效应器包括设置在管的远端端部上的柱形增强器，其中，一个或多个倾斜叶片设置在柱形增强器与管之间。在本公开内容的另一方面中，该端部效应器包括设置在管的远端端部分的壁的内表面上的一个或多个倾斜叶片。在本公开内容的另一方面中，该端部效应器包括在管的远端端部的壁上的一个或多个平流孔口。
摘要（英）：

The present disclosure is directed to an electrosurgical apparatus for generating plasma in electrosurgical applications. The electrosurgical apparatus includes an end effector disposed on a distal portion of a tube of the electrosurgical apparatus. The end effector mixes ambient air with an inert gas to increase the production of radical species. In one aspect of the present disclosure, the end effector includes a cylindrical augmenter disposed over a distal end of the tube with one or more tilted vanes disposed between the cylindrical augmenter and the tube. In another aspect of the present disclosure, the end effector includes one or more tilted vanes disposed on an inner surface of a wall of the distal end of the tube. In another aspect of the present disclosure, the end effector includes one or more advection apertures on the wall of the distal end of the tube.
