Abstract
A treatment unit for an endoscope, for example, a grasping unit is connected at a distal end of a manipulation wire that is connected to a first manipulation member. An inner tube slidably surrounds the manipulation wire. A proximal end of the inner tube is connected to a distal end of a second manipulation member. Further, an outer tube is provided to surround the inner tube and the manipulation wire. A proximal end of the outer tube is connected to a main body connected to the first manipulation a member by a connecting rod that the positional relationship between the manipulation wire and the outer tube along the axis is fixed. By moving the first and second manipulation members towards each other, the grasping unit is opened as the inner tube slides to uncover a part of the grasping unit which opens by resilience, while when the first and second manipulation members are spaced from each other, the inner tube slides to cover a part of the grasping unit forcing it closed.
