摘要

A capsule (3) as a medical device to be inserted into a body cavity has its longitudinal direction as an insert axis and a magnet (8) magnetized in the direction orthogonal to the insert axis is arranged at the center position of the insert axis. By turning ON a vibration (ON/OFF) switch (8f) of an operation input device (8) for a magnetic field generation device (4) arranged outside the body, the magnetic field generation device (4) generates a vibration magnetic field in the direction parallel to the insert axis of the capsule (3) and a force couple having the function line parallel to the insert axis functions on the capsule (3), so that the capsule (3) swings around the insert axis and advances smoothly along a luminal organ.
