Capsule medical apparatus system

A capsule medical apparatus system comprising:

• a rotating magnetic field generation apparatus that generates a desired rotating magnetic field in three-dimensional directions;
• a capsule medical apparatus that is introduced into a living body, includes a magnet and a needle with which the capsule medical apparatus punctures a luminal surface by projecting and retracting the needle in a rotation direction of the rotating magnetic field, and rotates in a direction of the rotating magnetic field when the rotating magnetic field is applied to the magnet;
• a step-out operation detecting unit that detects, when the needle is diagonally projected toward the luminal surface to puncture the luminal surface, an step-out operation by which the capsule medical apparatus is inversely rotated at a rotating speed larger than a rotating speed of the rotating magnetic field after rotating the capsule medical apparatus to the rotation direction of the rotating magnetic field is stopped;
• and
• a magnetic-field control instructing unit that controls the rotating magnetic field generation apparatus on the basis of a detection result performed by the step-out operation detecting unit.
