Surgical irrigation apparatus for cleaning and sterilizing wounds and surgical areas during surgery

摘要

An irrigation system includes an elongated, hand-held instrument for applying a solution spray to a surgical area of a patient during surgery. The instrument includes an elongated handle having an outer ribbed surface to be hand-held. The handle has a central passageway between an inlet end and a discharge end. A nose is secured to the discharge end of the handle with a flow control valve secured within the handle. Nozzles are selectively connected to the nose to create selected flow patterns at the surgical site. The valve has an external pushbutton actuator to control the solution flow through a passageway in the body and nose. A pressurized liquid supply includes a sealed disposable, liquid solution filled bag and a sterile tube connected to the inlet end of the body. The solution bag is releasably supported within a pressurizing bag which in turn is carried on a portable stand unit. A bulb pump or small pressurized cannister is coupled to the pressurizing bag, with a regulating valve, for establishing a pressure of about 100 to 600 mm therein. The irrigating solution flow is applied to the wound at about 8 to 15 psi. The solution bag, instrument and interconnected elements are all throw-away elements providing a sterile one-time irrigating apparatus.
