Endoscope treatment tool, endoscope device, and treatment method

Abstract

An endoscope treatment tool includes: a distal end part; an operating part into which an operation to the distal end part is input; and a soft portion that connects the distal end part and the operating part, and the operating part includes a fixing unit that attaches the operating part to an endoscope, and an operating part body that is capable of moving forward and backward with respect to the fixing unit and that is rotatable along a plane orthogonal to the forward and backward movement direction, and has a friction mechanism that generates a first frictional force between the fixing unit and the operating part body in a rotation direction of the operating part body and that generates a second frictional force between the fixing unit and the operating part body in the forward and backward movement direction, which is different from the first frictional force.
