Abstract

In the forward end portion of the flexible insulating tube of an electrosurgical instrument there is formed an opening or fenestra at the side surface thereof, and when an electrode wire is forced into the insulating tube, the working section thereof is outwardly looped through said opening, so that said looped working section is brought into contact with the tissue of the body cavity to resect the same. This instrument is introduced into a predetermined position of the body cavity using an endoscope while an operator is observing the endoscope.
