An endoscope treatment tool, comprising:

• a sheath;
• a handle body attached to a proximal end of the sheath;
• a rotation handle attached to a proximal portion of the handle body so that the rotation handle is rotatable relative to the handle body;
• a wire passing through the handle body;
• a slider attached to the rotation handle so that the slider is movable relative to the handle body and the rotation handle along a longitudinal axis of the rotation handle, wherein the slider is connected to a proximal portion of the wire;
• a conductive connector attached the handle body, wherein the wire passes through the conductive connector;
• and
• an elastic body located distally relative to the rotation handle, wherein the elastic body is in electrical contact with the conductive connector at a position distally relative to the rotation handle.
