1. a kind of capsule medical device guidance system, it is characterised in that possess:

  • The capsule medical apparatus of capsule-type, it possesses permanent magnet, is directed in the liquid in subject;

    Magnetic field generation section, it produces the magnetic field to the application of above-mentioned permanent magnet to guide above-mentioned capsule medical apparatus, and canThe direction in magnetic field caused by change in three dimensions;

    Control unit, it controls the magnetic field as caused by above-mentioned magnetic field generation section;

    First operation inputting part, it is used for the instruction in above-mentioned control unit and is used for carrying out magnetic guiding dimensionally to operate above-mentioned glueThe application in the magnetic field of capsule type medical device;

    AndVarying magnetic field button, it is used in above-mentioned control unit indicate to apply while the first magnetic field and the second magnetic field, wherein,Above-mentioned first magnetic field and above-mentioned second magnetic field are different from as the magnetic field indicated by above-mentioned first operation inputting part;

    Wherein, above-mentioned control unit accordingly enters with the input instruction from above-mentioned first operation inputting part to above-mentioned magnetic field generation sectionRow control, on the other hand, above-mentioned control unit is indicated accordingly, in above-mentioned capsule type medical with the input from varying magnetic field buttonDevice is controlled to produce while the plane internal rotation parallel with vertical axle in the state of being located at the liquid level of aforesaid liquidThe first magnetic field circled round centered on above-mentioned vertical axle with the defined cycle, and be controlled and be used to make to produce to producePermanent magnet is stated to the second magnetic field of the polarity of vertical lower direction movement, and applies above-mentioned first magnetic field and above-mentioned the simultaneouslyTwo magnetic fields.
