Abstract

A magnetically guiding system (1) includes: a capsule medical device (10) that has a magnet provided therein; an information acquiring unit (4) that acquires physical information about magnetic guiding of the capsule medical device (10); a magnetic field generating unit (2a) that generates a magnetic field for magnetically guiding the capsule medical device (10); and a control unit (8) that sets a magnetic field condition based on the physical information acquired by the information acquiring unit (4) and controls the magnetic field generating unit (2a) to generate a magnetic field corresponding to the magnetic field condition.

Description

technical field [0001] The present invention relates to a magnetic guidance system and a magnetic guidance method for guiding a medical device introduced into a subject by magnetic force. Background technique [0002] Conventionally, in the field of endoscopes, a capsule-type medical device having an imaging function and a wireless communication function has appeared. In order to observe the inside of an organ of a subject such as a patient, the capsule medical device is introduced into the subject by oral ingestion or the like. Thereafter, the capsule medical device inside the subject sequentially captures images of the inside of the organ at predetermined intervals while moving inside the organ by peristaltic motion or the like (hereinafter, sometimes referred to as in-vivo images), and the obtained in-vivo images are In turn wirelessly sent to the outside. The capsule medical device inside the subject repeatedly performs the imaging and wireless transmission of the in-...
