ABSTRACT:
An electrosurgical instrument for spinal procedures comprises a generally scoop-shaped cup whose periphery is electrically active and is capable of applying RF electrosurgical currents to spinal tissue. The active electrode may comprise an exposed bare wire at the leading edge of the cup. A conduit in a handle section can convey suction to the cup. A tissue clearing member is pivotably mounted on or inside the cup and can be manipulated via a lever on the handle to help dislodge tissue. The tissue clearing member may be a radially-extending vane for rotation in the plane of the cup edge. The tissue clearing member may also be made electrically active thus selectively providing unipolar or bipolar operation.
