Aspirator/irrigators designed to fragment and remove soft tissue during surgical procedures. These devices use mechanical vibration at ultrasonic frequencies while also providing suction and/or irrigation. These devices typically consist of a control unit that includes a generator which delivers an ultrasound energy output. They also include a pump used for suction and irrigation, and a set of detachable handpieces that are usually frequency-specific according to the place and nature of the tissue. The ultrasonic energy is converted in mechanical vibration in the dedicated handpiece; the vibrations are then applied to the tissues at a frequency appropriate for debridement. Ultrasound surgical aspirator/irrigators are used in a variety of general surgery, neurosurgery, and laparoscopic procedures. They are also used in liposuction and other soft tissue surgical procedures performed in places such as the liver, spleen, and kidneys.
