ABSTRACT:
In an endoscope apparatus, an inserting instrument is insertable through an inserting portion of an endoscope so as to have a distal end portion projected from a distal end of the inserting portion. The inserting instrument comprises an outer tubular envelope and an elongated rod-like member located at a distal end of the envelope. An operating device located at a proximal end of the envelope is connected to the rod-like member through a wire member extending through the envelope. The rod-like member is operated to be moved between an inoperative position where the longitudinal axis of the rod-like member extends substantially in coaxial relation to the envelope and an operative position where the longitudinal axis of the rod-like member extends across an extended line of the envelope. The inserting instrument may be utilized as guiding and/or measuring instrument. For the guiding instrument, the rod-like member located in the operative position is brought into engagement with an object to be inspected, to guide the inserting portion thereinto. For the measuring instrument, the rod-like member has carried thereon graduations for measurement.
