A magnetic actuator for colon endoscope navigation was fabricated. We conducted motion tests of the actuator in the small intestine of a pig and the large intestine of a living dog. The actuator is composed of a permanent magnet and a spiral structure, and is attached to the pointed end of an imitation endoscope. When a rotational magnetic field is applied, the actuator rotates and moves in the intestine. It was able to draw the imitation endoscope forward without injuring and changing the shape of the intestine. This result shows that the actuator has the potential to be use for colon endoscope navigation.
