PROBLEM TO BE SOLVED: To provide a medical system including a self-propelled capsule endoscope driven forward by the oscillation of a fin portion in the body, and a capsule control device for controlling the self propulsion of the capsule endoscope in the body, wherein the medical system facilitates precise control of the movement direction of the capsule endoscope.SOLUTION: The medical system 1 includes: the capsule endoscope 2 mounted with a magnet 21 having a magnetization direction in the axial direction, provided with the fin portion 2b at the axially rear end of an endoscope body portion 2a, and self-propelled in the body and the capsule control device 3 for generating a magnetostatic field whose direction is controlled three-dimensionally and an alternating magnetic field orthogonal to the magnetostatic field, and controlling the self-propulsion of the capsule endoscope 2 outside the body. The capsule endoscope 2 turns by receiving the magnetostatic field so that the magnetization direction is parallel with the direction of the magnetostatic field, the magnet 21 moves in response to the alternating magnetic field, and then the fin portion 2b is turned and oscillated to generate an axial driving force.COPYRIGHT: (C)2013,JPO&INPIT【課題】体内においてヒレ部の振動により推進する自走可能なカプセル内視鏡と、体外においてカプセル内視鏡の自走を制御するカプセル制御装置と、を備えた医療装置において、カプセル内視鏡の進行方向の精密な制御が容易にできる医療装置を提供する。【解決手段】この医療装置1は、軸方向に磁化方向を有する磁石21が搭載され、内視鏡本体部2aの軸方向後端部にヒレ部2bが設けられて体内において自走可能なカプセル内視鏡2と、3次元で方向が制御される静磁場とそれと直交する交流磁場を発生することにより体外においてカプセル内視鏡2の自走を制御するカプセル制御装置3と、を備えており、カプセル内視鏡2は、静磁場を受けてその静磁場の方向に磁化方向が平行になるように回動し、交流磁場を受けて磁石21が応動しそれによりヒレ部2bが曲がって振動して軸方向の推進力が生じる。【選択図】図1
