Abstract: An adaptor for an irrigation set which includes an elongated cannula having an enlarged portion opposite the operative end thereof and a downwardly extending channel removably coupled to the manifold of a standard or label suction irrigation set for suction and irrigation fluids. The manifold is connected to suction and irrigation lines through respective valves. A bracket extends downwardly from the enlarged cannula portion and a hand control panel is mounted thereon with switches to activate cutting and electrocoagulation with an electrode, which is retractable within the cannula.

Abstract: A versatile irrigation system dissector for laparoscopic surgery comprises an elongated lumen having an elongated slim tip electrode slidably mounted therein and having a cutting tip extendable therefrom at one end. The lumen is connected at the other end to a manifold mounted on a handle, which includes a pair of switches to regulate the inlet and outlet flow through the lumen for irrigation and suction purposes. A control panel on the handle regulates the current to the tip for either cutting or coagulating. Thus, several operations may be performed with a single handheld instrument in a highly efficient and rapid action.

Abstract: The Christoudias endodissector is utilized for dissecting, wiping, sponging or cleaning tissues during endoscopic surgery. The instrument includes a mesh gauze body at one end which is held securely and housed in a recess on the head portion of the instrument by teeth on a fixed and a pivotal jaw. The lower part of the head portion is mounted within a resiliently backed cylindrical locking sheath. The lower head portion becomes an elongated main stem which is mounted within a handle sheath at the other end of the instrument. A locking pin on the stem engages a groove on the locking sheath to maintain the jaws in position. Alternate embodiments involve a mushroom dissector and a cocoon dissector named after the configuration of the gauze body. The invention also includes the method of making and using the Christoudias endodissector.
