Abstract
(EN) The invention has for its object to provide a manipulator wherein the size of a curved portion is reduced and the internal architecture of the curve portion is simplified. The manipulator 100 comprises an insert part that is capable of being inserted into the body cavity, a movable part that is located at a distal end of the insert part and movable in any direction, a drive unit that is provided on a proximal-end side of the insert part, a first elongated member that is connected to the drive unit and located in the insert part, and displaces in response to operation of the drive unit, a second elongated member that is different from the first elongated member and has a distal end connected to the movable part, and a deceleration mechanism that urges displacement of the second elongated member in association with displacement of the first elongated member, and makes a second amount of displacement of the second elongated member smaller than a first amount of displacement of the first elongated member.
(FR) La présente invention concerne un manipulateur présentant une partie courbe de taille réduite dont l'architecture interne est simplifiée. Le manipulateur 100 comprend une partie formant insert pouvant être insérée dans la cavité du corps, une partie mobile située à une extrémité distale de la partie formant insert et pouvant se déplacer dans n'importe quelle direction, une unité d'entraînement prévue sur un côté de l'extrémité proximale de la partie formant insert, un premier élément allongé raccordé à l'unité d'entraînement et situé dans la partie formant insert, et qui se déplace en réponse au fonctionnement de l'unité d'entraînement, un second élément allongé qui est différent du premier élément allongé et dont l'extrémité distale est raccordée à la partie mobile, et un mécanisme de décélération qui pousse le déplacement du second élément allongé en association avec le déplacement du premier élément allongé, et qui rend une seconde quantité de déplacement du second élément allongé inférieure à une première quantité de déplacement du premier élément allongé.
