内容記述
Movement of a capsule endoscope in body depends only on the peristalsis and gravity. Therefore, there is a problem such as prolongation of the examination time. In addition, observation of the site aimed at is not easy. It is required to control the movement of the capsule endoscope to reduce the oversight of a lesion. Towards the resolution of the problems, this research proposes a magnetic guide method using a magnetic guide magnet. It is guided the capsule endoscope by the magnetic force generated from the magnetic guide magnet. Assuming the distance between the surface of the body and digestive organ, the goal of guide distance is 100 mm. Estimates of necessary magnetic field for the guide of the capsule is 17 mT. This paper reports the design of the magnetic guide magnet which generate more than magnetic field of 17 mT to a distance of 100 mm.
