A bipolar radiofrequency (RF) device for treating tissue in the presence of an electrically conductive fluid includes a headpiece and a probe. The handpiece has a motor drive, a receiving channel, and an active electrical contact on an inner wall of the receiving channel. A return electrical contact is disposed proximally of the active electrical contact on the inner wall of the receiving channel. A probe includes a proximal hub and an elongated shaft extending distally about a longitudinal axis from the proximal hub, and the hub being may be inserted into and removed from the receiving channel of the handpiece. A working end of the probe is located at a distal end of the elongated shaft, and the working end includes an active electrode and a return electrode. A return electrical contact is located proximally of an active electrical contact on an outer surface of the hub. In this way, the return electrical contacts in the receiving channel and on the outer surface of the hub, respectively, and the achieve electrical contacts in the receiving channel and on the outer surface of the hub, respectively, engage each other when the hub is inserted into the receiving channel of the handpiece.
