摘要:
An electrosurgical wand is provided and includes a handle and an elongate shaft coupled to the handle and extending distally from the handle along an axis. An active electrode is disposed at a distal end of the electrosurgical wand. A return electrode abuts the elongate shaft and extends along and annularly about the axis. The return electrode has a top side adjacent the active electrode and an opposite bottom side and defines a notch. A support member is disposed in the notch between the electrodes and transitions curvilinearly from the notch to define a front surface extending laterally across and axially from the return electrode. The front surface tapers downwardly from the active electrode to define a first portion defining a first convex outer surface and also extends toward the bottom side of the return electrode to define a second portion defining a second convex outer surface.
