(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.
(ZH) 本发明的目的是提供一种操纵器，在所述操纵器中，减小了弯曲部分的尺寸并且简化了弯曲部分的内部构造。操纵器(100)包括：插入部件，其能够插入体腔中；活动部件，其位于插入部件的远端处并且能够在任何方向上移动；驱动单元，其设置在所述插入部件的近端侧；第一细长构件，其连接至驱动单元并且位于插入部件中，并且响应于所述驱动单元的操作而移位；第二细长构件，其不同于第一细长构件并且具有连接至活动部件的远端；以及减速机构，其以与所述第一细长构件的移位相关联的方式推动所述第二细长构件的移位，并且使所述第二细长构件的第二位移量小于所述第一细长构件的第一位移量。
