ABSTRACT:
An accessory of an endoscope includes a tube. At least the distal end portion of the tube is formed to have a predetermined resilience, and a plurality of slits extending in the axial direction of the tube are formed at the distal end portion of the tube. A mechanism is provided to bias the distal end of the tube towards the proximal end thereof so that the band portions between the plurality of slits radially expand to define a plurality of openings. The mechanism can forcibly strain the band portions and forcibly and radially expand the band portions.
