1. A bipolar electrosurgical scraper device comprising:
- a handle;
a blade distal to the handle, the blade having a front side, a rear side, a thickness and a beveled distal end, the beveled distal end terminating distally in a curved scraping edge at a rear side of the blade;
the beveled distal end including a first electrode and a second electrode, the first electrode and the second electrode provided along a width of the blade and spaced apart with respect to the thickness of the blade, wherein the beveled distal end is at a bevel angle with respect to a longitudinal axis of the device, and wherein the bevel angle is uniform along the thickness of the blade;
a fluid passage extending distally with the handle; and
at least one fluid outlet in fluid communication with the fluid passage.
