Abstract
A snare assembly is disclosed which is inserted into a region of interest of a human body through a channel of an endoscope. The snare assembly comprises at least one flexible tube, a folded snare which is so inserted into the flexible tube as to be movable back and forth and having a folded end portion and a relatively short snare section, a slide means attached to a base end portion of the short snare section, and a stopper movable back and forth and, upon the forward movement of the slide means, abutting against the slide means to restrict an extension length of the short snare section. A fixing means is provided on the base end portion of the tube and stopper, whereby after a relative position between the tube and the stopper is adjusted the stopper and tube can be fixed at that relative position.
