摘要： The specific gravity of a capsule-type endoscope according to the invention is set to be lower than that of liquid in an organ, so that the capsule-type endoscope is floated on a liquid surface of the liquid. A center of gravity of the capsule-type endoscope is set to a position deviated from a center of a casing, so that the casing is maintained in a specific floating position while being floated on the liquid surface. A boundary between the casing and the liquid surface is formed within a projection plane, which is obtained by projecting the casing in the specific floating position perpendicularly to the liquid surface, at a position excluding an outer periphery of the projection plane Ka.

摘要： A posture and a position of a capsule endoscope 31 in a fluid 7 are made unstable and susceptible to an influence of a flow of the fluid 7 by constructing the capsule endoscope in such a way that the capsule endoscope 31 is equipped in a capsule casing having an approximately cylindrical trunk, a center of gravity of the capsule endoscope 31 is approximately in a volume center, and a specific gravity of the capsule endoscope 31 is approximately equal to that of the fluid 7 injected into a body cavity, thereby causing the capsule endoscope 31 to move to an intraluminal center using a difference of flow rate of the fluid 7 generated in large intestine and the like where a luminal diameter is large to stably capture desired intraluminal images by an imaging optical system.

摘要： A capsule medical system includes a capsule medical apparatus, a selecting unit, and a control unit. The capsule medical apparatus is introduced inside a subject and includes an imaging unit for taking an in-vivo image of the subject, a treating unit for treating a living tissue in the subject, and a driving unit for contributing to movement of the capsule medical apparatus. The selecting unit selects a treatment target of the treating unit from the in-vivo image. The control unit determines a relative distance between the treatment target and the treating unit, and 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.
