Abstract
An endoscope apparatus comprises an endoscope and an elongated operating instrument adapted to be inserted into the endoscope. The endoscope includes an inserting portion extending from an operating body and adapted to be inserted into a body cavity. A guide tube is provided on the operating body so as to communicate with a guide channel formed through the operating body and the inserting portion. The operating instrument is inserted from the guide tube into the guide channel while being guided by the guide tube, so that a distal end of the operating instrument projects from the guide channel into the body cavity. The guide tube has a bent configuration and is supported on the operating body for turning movement relative thereto.
