A cutting apparatus is provided with both a rotating inner blade and a stationary outer blade at its distal end and is connected to a drive unit disposed in the proximal region. The outer blade is spaced from the inner blade to form an irrigation passage through which an irrigation liquid is passed. A flushing duct is provided for fluid communication to the distal end. Additionally, a suction passage is provided to exhaust tissue particles.
