PURPOSE:To provide a medical tube which is easily operated from the hand side and whose operation is surely transmitted to the end part for enhancing the guiding performance of the end part, and also which is capable of being miniaturized and slenderized in its diameter and further which is excellent in responsiveness. CONSTITUTION:A medical tube is provided with a cylindrical ion exchanger resin molding 4 and at least two pairs of electrodes 5a, 5b, 15a, and 15b formed in the positions where they have been held between the inner and outer circumferences of the ion exchanger resin molding 4, to the curving part which becomes the introducing part to the target portion at the end of a tube body 2. A polymer actuator 3 constituted in such a way that when a voltage is applied to these pairs of electrodes, the ion exchange resin molding 4 can be deformed is arranged, and also the respective electrodes of the polymer actuator 3 and the operational control part 7 of the actuator 3 are electrically connected with lead wires 6a, 6b, 16a, and 16b extending in the lengthwise direction of the tube body 2. |
