Turning the capsule type medical device which is introduced into in vivo due to the rotary magnetic field which turns to 3 dimensional direction of desire, the needle which it provides in the capsule type medical device when the stab it does, after revolution of the capsule type medical device to rotation direction of the rotary magnetic field stops, it inspects the loss of synchronism operation where the capsule type medical device turns conversely at the rotary speed which is larger than rotary speed of the rotary magnetic field on the lumen surface with loss of synchronism operational inspection expedient, it controls the rotary magnetic field supply system which generates the rotary magnetic field on the basis of the inspection result due to loss of synchronism operational inspection expedient.生体内に導入したカプセル型医療装置を所望の3次元方向に回転する回転磁界によって回転させて、カプセル型医療装置に設けた針を内腔表面に穿刺する場合に、回転磁界の回転方向へのカプセル型医療装置の回転が停止した後に回転磁界の回転速度よりも大きい回転速度でカプセル型医療装置が逆回転する脱調動作を脱調動作検知手段によって検知し、脱調動作検知手段による検知結果をもとに、回転磁界を発生させる回転磁界発生装置を制御する。
