PURPOSE:To form an operational control means in simple construction and small size and make the insertion part in small dia. by using a mechanochemical substance which is installed in the insertion part and bends and drives a bent part through contraction and expansion. CONSTITUTION:Inside a resin sheath 24 to constitute an insertion part 2, a pair of accommodation chambers 25a, 25b are formed, which are situated eccentrically to the peripheral side both above and below and which have a longer side in the longitudinal direction of this insertion part 2, and inside these chambers mechanochemical polymers (substance) 26a, 26b are accommodated. Electrodes 27a, 27b, 27c, 27d are connected with the ends of these mechanochemical polymers 26a, 26b, while a lead 28 is connected with those of electrodes which are situated nearer the foremost part, and further two leads 29, 30 are connected with the other electrodes 27c, 27d situated near the operator. These leads are leading and connected to a power supply unit 15 via the above-mentioned insertion part 2, a divergent point 4, universal cord 11, connector 12, and cable 14. |
