<p>An endoscope for intubating an endotracheal tube includes an elongated insertion section (1) having at least an image-transmitting fiber bundle (5) and an illumination-light-transmitting fiber bundle (7), a handle operation section (2) coupled to a proximal end of the insertion section (1), a bending operation mechanism (11) provided in the handle operation section (2) and a bending mechanism (13) for bending the insertion section (1) provided so as to extend from the inside of the insertion section (1) to the bending operation mechanism (11), the bending mechanism including a long elastic member (9) having one end positioned in the vicinity of the distal end portion of the insertion section (1) and the other end fixedly coupled to the bending operation mechanism (13), a push-pull member (10) having one end positioned in the vicinity of the distal end portion of the insertion section (1) and the other end connected to the bending mechanism (11), a hollow member (12) for coupling together a distal end portion of the elastic member (9) and a distal end portion of the push-pull member (10) so as to cause the portions to oppose each other along a bending direction, wherein the distal end portion of the elastic member (9) and the distal end portion of the push-pull member (10), which are coupled together with the hollow member (12), are provided integrally so as to provide a free end. <IMAGE></p> |
