Abstract

Magnetic actuator for colonoscope navigation is fabricated. The actuator composed of tube-shape permanent magnet and spiral structure that made by rubber. The magnet is magnetized to the direction of its diameter. By applying the rotational magnetic field the machine rotate and moved in an intestine. The actuator is attached on an end of simulated endoscope. The actuator with flexible air tubes can move in small and large intestines of pig. This result suggests that the actuator have great possibility for colonoscope navigation.
