<p>A bending operation apparatus is designed such that a bending portion (2) which can be bent/deformed is formed at the distal end of an insertion portion (3), and the proximal end portion of the insertion portion (3) is connected to an operating portion on the manual operation side which serves to remotely control a bending operation of the bending portion (2). The apparatus includes three angle wires (14, 16, 18) arranged in the bending portion (2), three actuators (34, 36, 38) for independently operating the three angle wires (14, 16, 18), and a control means for arbitrarily controlling the operating amounts of the three angle wires (14, 16, 18) through the three actuators (34, 36, 38). <IMAGE></p> |
