Abstract
An apparatus and method for minimally invasive surgery using a cutting tool with rotational cutting edges. The surgical instrument includes a tube having a distal end and a cutting edge at the distal end. A handle is attached to the proximal end of the tube. Within the tube is a shaft having a longitudinally extending blade at its distal end that is adjacent to the distal end of the tube. The blade is revolvable about the longitudinal axis of the instrument to provide rotational cutting action. One or both of the blade and the cutting edge on the tube can be electrically energized to provide for electrocauterization of the body tissue being cut.
