PROBLEM TO BE SOLVED: To introduce and operate a head of a treatment tool easily and precisely by arranging a bendable operating means and a treatment tool standing operating means so as to be operated by different fingers of a hand grasping and keeping the operating part. SOLUTION: A bendable part 3 which can be bent at an arbitrary angle by means of remote control from an operating part 1 is formed at the neighborhood of a head of an inserting part 2 which is sheathed with a flexible tube, in an endoscope whose operating part 1 is grasped by a left hand of an operator. A bending operation control 8 for bending the bendable part 3 by remote control is supported on bearing freely-rotationally on an upper half part of right side face of the operating part 1, and also gas and water feeding operating valve 9 and an aspiration operating valve 10 and the like are arranged on the upper half part of the front face of the operating part 1. This operating part 1 is grasped by a left palm and the third and the fifth fingers of the operator, and the bending operating control knob 8 can be always operated by the first finger of the left hand, and either the gas and water feeding operating valve 9 or the aspiration operating valve 10 can be operated selectively by using the second finger. |
