Patent ID: 8419621

Claim:
A capsule medical system comprising: a capsule medical apparatus that is introduced into a subject, and includes an imaging unit for taking an in-vivo image of the subject, a treating unit for treating a living tissue inside the subject, and a driving unit for contributing to movement of the capsule medical apparatus; a selecting unit that selects a treatment target of the treating unit from the in-vivo image; a control unit that determines a relative distance between the treatment target and the treating unit, and that moves the capsule medical apparatus in an imaging direction of the imaging unit by a distance corresponding to the relative distance using the driving unit; a communicating unit that is arranged inside the capsule medical apparatus and that transmits at least the in-vivo image to an external device; an external communicating unit that receives the in-vivo image transmitted by the communicating unit; and a display unit that displays the in-vivo image received by the external communicating unit, wherein the selecting unit selects the treatment target of the treating unit from the in-vivo image displayed by the display unit; the imaging unit is arranged at a fixed position relative to the treating unit, the driving unit moves the capsule medical apparatus to a specific position inside the subject at which the in-vivo image showing the treatment target at an image edge portion can be taken by the imaging unit, and the control unit determines the relative distance that is a sum of a specific distance between the treatment target and the imaging unit and an inter-parts distance between the imaging unit and the treating unit, when the capsule medical apparatus stops at the specific position inside the subject in contact with an organ internal wall, the specific distance being defined by an angle of view of the imaging unit.
