WIPO Patent Application WO/2017/175373
Kind Code:
A1
Abstract:
In order to suppress the occurrence of path length differences in a plurality of drive power transmission members for all curve lengths of an insertion part, reduce friction on the drive power transmission members, and prevent a decrease in control properties of a movable part, the flexible manipulator (1) pertaining to the present invention is provided with a slender and flexible tube-shaped insertion part (2), a movable part (4) disposed at a distal end of the insertion part (2), a drive part (5) disposed at a proximal end of the insertion part (2), two or more slender drive power transmission members for transmitting motive power of the drive part (5) to the movable part (4), and flexible path formation members (8) for forming two or more paths penetrating through the drive power transmission members in the longitudinal direction thereof on the outside in the radial direction with respect to the central axis of the insertion part (2) inside the insertion part (2).
