MANIPULATOR

摘要

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.
