Cleaning is the most important step in reprocessing a medical device. Without adequate cleaning, disinfection and sterilization can’t be performed effectively. Ultrasonic cleaning can be particularly useful for hard to reach areas on a device, such as on fine serrations or box lock joints, but it can also be gentle on delicate instruments such as microsurgical and ophthalmology devices.

The ultrasonic cleaning process uses mechanical vibrations to agitate a solution to aid in the removal of soil from surfaces, and in some cases inside lumens, of surgical devices. The sound waves in the liquid produce microscopic implosions of bubbles that collapse on contact with surfaces, creating a vacuum-like scrubbing action dislodging soil from surfaces; this effect is called cavitation. The cavitation then removes bioburden from the...
