A mains electricity (AC-powered) device designed to irrigate, wash, and evacuate debris from general soft-tissue and orthopaedic surgical sites (e.g., for soft-tissue wound or bone debridement, site clearing, bone cement residue removal) by regulating a pulsatile jet of sterile fluid (typically saline). It is typically an electromechanical unit that includes a pump for irrigation/infusion of fluids, an extractor (frequently using vacuum), and controls for the rate of irrigation/infusion and withdrawal of the fluid; it usually operates with separate kits that include handpieces, tubing, and detachable tips (applicators) of various shapes and sizes for specific surgical applications.
