ABSTRACT:
A unique four function surgical instrument that performs aspiration, irrigation, dilation and cauterization with an innovative trigger mechanism. An embodiment is “gun-like” in configuration having a housing with a depending handle and a protruding trigger, a forward extending pair of forceps-like arms that terminate in dilation/cauterization tips and a common conduit between the forceps-like arms. The unique trigger mechanism utilizes a pinch valve concept where the trigger button has an elongated portion that has two slide surfaces with offset a recesses that act like tracks on which pinch sliders follow and the pinch sliders act like valve stems that squeeze close and allow to open silicone tubing. The end result, being a single poll, two stage actuator such that a half a pump of the trigger delivers irrigation or aspiration and a full pump delivers the other. The instrument provides the advantages of small size, ergonomical and all-in-one so as to eliminate the need for a surgeon to fumble around in switching between instruments.
