Features to promote removal of debris from within ultrasonic surgical instrument

An instrument, comprising:

• (a) an ultrasonic blade, wherein the ultrasonic blade defines a distal opening, wherein the ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade, wherein the ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade;
• (b) a first fluid port in fluid communication with the distal opening of the ultrasonic blade;
• (c) an irrigation member positioned proximate to the ultrasonic blade and at least partially defining a fluid lumen distally extending to an irrigation opening positioned adjacent to a distal end of the ultrasonic blade, wherein the fluid lumen is offset apart from the ultrasonic blade;
• (d) a second fluid port in fluid communication with the irrigation opening of the irrigation member via the fluid lumen extending therebetween;
• and
• (e) a fluid communication assembly, wherein the fluid communication assembly is configured to:
• (i) couple the first fluid port with a fluid source,
• (ii) couple the first fluid port with a suction source, and
• (iii) couple the second fluid port with the fluid source.

• and
• (f) a clamp arm movably secured relative to the ultrasonic blade from an open position away from the ultrasonic blade toward a closed position adjacent to the ultrasonic blade to cooperate with the ultrasonic blade in the second mode, wherein the ultrasonic blade extends along a longitudinal axis in a longitudinal direction and the clamp arm has a distal arm end portion aligned in a transverse direction with the irrigation opening of the irrigation member in the closed position.
