发明名称 IRRIGATION/ASPIRATION CANNULA
摘要 <p>The invention provides an irrigation and aspiration device for use in laparascopic and other types of surgery. When connected to existing irrigation and suction sources, the device provides fingertip control of the fluid connections between the sources and a tube. The device comprises a valve housing with two valve assemblies inside, mounted and configured to take advantage of the static pressure supplied by the sources for increasing seal integrity of the valves. The internal chambers of the valve housing are also configured such that when one valve is open, the pressure differential across the other valve is increased, further increasing its seal integrity.
