    摘要: A bending mechanism comprising a tubular body or linear body having a bending part, a movable part which can move in the lengthwise direction of said tubular body or linear body, two actuators formed to antagonize via said movable part, and a pull wire which extends in the lengthwise direction along the bending part, one end of the wire being fixed to one end side of the bending part and the other end of the wire being fixed to the movable part set at the other end side of the bending part, wherein at least one of the two actuators is a shape memory element, and a stereoscope. The bending mechanism of the present invention is free of displacement of movable part when bending action is not needed, since two actuators are used which antagonize each other via movable part, whereby buckling of the bending part can be prevented. The simple structure of activator unit of the present invention facilitates reduction of the size of the structure. The stereoscope of the present invention is free of buckling of image guide and the like, and angle of convergence can be adjusted easily and a desired three-dimensional view can be obtained easily.

    摘要: Un dispositif s'insérant dans le corps d'un mammifère comporte un tube allongé ou une canule (22), un élément élastique (24) pour infléchir la canule, et un élément de redressement (26) empêchant l'élément élastique (24) d'infléchir la canule. L'élément de redressement (26) et l'élément élastique (24) sont susceptibles d'un mouvement axial relatif, de sorte que l'élément de redressement (26) peut être positionné pour permettre ou interdire à l'élément élastique d'infléchir la canule. De préférence, l'élément élastique (24) est constitué d'un alliage superélastique à mémoire de forme. D'autres versions du dispositif sans élément de redressement sont décrites.

    摘要: 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).
