Abstract

The Christoudias endodissector is an instrument 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 which is securely affixed on a complimentary shaft. An alternate embodiment involves a tubular instrument onto which a tubular endodissector tip is attached thus forming a working port through which additional instruments can be inserted. The invention also includes the method of making and using the Christoudias endodissector.
