Abstract
A bipolar electrosurgical scraper device is provided comprising a handle, a blade having a thickness and a beveled distal end with the beveled distal end terminating distally in a scraping edge. The beveled distal end includes a first electrode and a second electrode with 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. The device also comprises a fluid passage at least one fluid outlet in fluid communication with the fluid passage.

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 scraping edge at the 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.
