Abstract: A variable stiffness device includes a shape-memory unit formed of at least two hollow shape-memory members connected together. Each of the shape-memory members is transitionable in phase between a first phase in which the shape-memory member is in a low stiffness state and a second phase in which the shape-memory member is in a high stiffness state. The shape-memory member in the high stiffness state has a higher level of stiffness than in the low stiffness state. Hollow portions of the shape-memory members are connected together so that the shape-memory unit has a lumen-like inner space configured to allow fluid for cooling the shape-memory members to flow. The variable stiffness device also includes a heating member configured to heat the shape-memory members.

Abstract: An endoscope includes a flexible member and a variable stiffness apparatus installed in the flexible member. The variable stiffness apparatus includes a first longitudinal member and a second longitudinal member movable along the first longitudinal member. The first longitudinal member includes a first high bending stiffness portion and a first low bending stiffness portion. The second longitudinal member includes a second high bending stiffness portion, a second low bending stiffness portion, and a soft member arranged in the second high bending stiffness portion and the second low bending stiffness portion. Stiffness of part of the variable stiffness apparatus in a longitudinal axis direction is varied by changing a relative position of the first and second longitudinal members.
