Bimanual aspirating unit 21g cannula tip

The Bimanual Aspirating Unit (BAU) with a 21-gauge cannula tip is typically used in medical and dental procedures, particularly for aspiration or suction purposes. The "bimanual" part suggests that the procedure or device requires the use of both hands for optimal control and efficiency. In dentistry, this could refer to a technique for administering local anesthesia or aspirating fluids during surgeries like implant placements or extractions.
