Abstract
An actuator for a treatment tool including: a tube having a distal end configured to rotatably support the treatment tool; a twisting wire disposed along a longitudinal axis of the tube, the twisting wire having a distal end and a proximal end, the treatment tool being connected to the distal end of the twisting wire, the twisting wire being actuated by applying a tensile force at the proximal end, the twisting wire converting the tensile force into rotation of the treatment tool around the longitudinal axis of the tube; and at least one wire movable in a longitudinal direction to actuate the treatment tool, the at least one wire actuating the treatment tool separately from actuation of the twisting wire to rotate the treatment tool.
