An endoscope has a flexible tube and a bendable tube connected to one end of the flexible tube in which an image guide is inserted and a control section connected to the other end of the flexible tube and having an eyepiece section connected to one end of the image guide to permit observation of a region of interest of a human being and a knob for operating the bendable tube to permit it to be bent. A distal end section of the endoscope is connected to the other end of the bendable tube and has a viewing window connected through an optical system to the other end of the image guide. One ultrasonic probe is provided in proximity to the viewing window and has a directionality in a direction substantially the same as that of an optical axis of the viewing window. |
