    摘要: An flexible tube insertion apparatus includes a tubular insertion section including a bending portion and a flexible tube portion, variable stiffness sections to cause a change in a level of a bending stiffness of the flexible tube portion, a variable stiffness control section that controls the change in the bending stiffness by the variable stiffness sections; and a time setting section that sets a time period. The variable stiffness control section causes the bending stiffness of the variable stiffness sections to change in such a manner that the relationship of levels between the bending stiffness of adjacent variable stiffness sections is switched at the set time period when the variable stiffness control section determines that the flexible tube portion is passing through a flexure of the subject.

    摘要: A flexible tube insertion apparatus includes an insertion section, a stiffness variable unit that changes a bending stiffness of the insertion section and a detection unit that detects an advance that is a movement toward a distal end of the insertion section and a retreat that is a movement toward a proximal end of the insertion section. A controller controls the stiffness variable unit to change the bending stiffness of the insertion section to a first bending stiffness when the detection unit has detected the advance of the insertion section, and that controls the stiffness variable unit to change the bending stiffness of the insertion section to a second bending stiffness higher than the first bending when the detection unit has detected the retreat of the insertion section.
