Abstract

An ultrasonic surgical instrument that supports an ultrasonically excited blade and an outer sheath that can be selectively rotated relative to each other to bring a distal cutting tip of the blade into contact with at least one cutting surface formed on a distal end of the outer sheath. In some embodiments, the distal cutting tip may contact two cutting surfaces located on opposing sides of an opening in the outer sheath through which the distal cutting tip protrudes. Tissue pads may be attached to the cutting surfaces. Various embodiments also include at least one suction lumen.
