Abstract
The present invention realizes a medical device guidance system capable of improving propulsion control characteristic. The capsule guidance systemincludes a rotating electromagnetic field generating devicefor generating a rotating electromagnetic field for applying from the outside of a subject into the subject; a capsuleto be inserted into the body cavity of the subject; a magnetprovided in this capsuleand acting on the rotating electromagnetic field generated by the rotating electromagnetic field generating device; a spiral projection portionprovided on the outer peripheral surface of the capsuleand converting the rotational movement generated by the magnetinto a thrust; a controllerfor controlling the rotating electromagnetic field generating deviceto continuously change the state of the rotating electromagnetic field generated by rotating electromagnetic field generating device; and a capsule rotational direction pattern generatorfor interchanging the rotational directions of the rotating electromagnetic field generated by the rotating electromagnetic field generating devicefor each set rotational direction.
