ABSTRACT:
The present invention realizes a medical device guidance system capable of improving propulsion control characteristic. The capsule guidance system1includes a rotating electromagnetic field generating device4for generating a rotating electromagnetic field for applying from the outside of a subject into the subject; a capsule3to be inserted into the body cavity of the subject; a magnet16provided in this capsule3and acting on the rotating electromagnetic field generated by the rotating electromagnetic field generating device4; a spiral projection portion12provided on the outer peripheral surface of the capsule3and converting the rotational movement generated by the magnet16into a thrust; a controller6for controlling the rotating electromagnetic field generating device4to continuously change the state of the rotating electromagnetic field generated by rotating electromagnetic field generating device4; and a capsule rotational direction pattern generator41for interchanging the rotational directions of the rotating electromagnetic field generated by the rotating electromagnetic field generating device4for each set rotational direction.
