摘要： A capsule endoscope includes a capsule-shaped casing and an imaging unit for taking an image of an inside of an organ in a state where the capsule endoscope is floating in liquid introduced inside the organ of a subject. Specific gravity of the capsule endoscope to the introduced liquid is ρ; a plane divides the capsule endoscope such that a volume ratio is to be ρ:1−ρ. A straight line that connects a center of volume of a portion whose volume ratio is ρ and a center of gravity of the capsule endoscope is substantially perpendicular to the plane. The center of gravity is present at a position farther distant from the plane than the center of volume. A surface of a boundary of a field of view that forms an angle of view of the imaging unit and the plane do not intersect outside the capsule endoscope.

摘要： An operating device operates a capsule endoscope with 6 degrees-of-freedom motion by using a magnetic field generator with respect to the capsule endoscope inserted into the subject. The operating device includes an operating unit including a fixed unit and a movable unit, and a force sensor incorporated in the operating unit. The operating unit has a three-dimensional shape substantially identical to the capsule endoscope and is a holdable size. The force sensor detects force information of the movable unit when the movable unit of the operating unit is operated once or continuously. The force information detected by the force sensor is output as instruction information for instructing 6 degrees-of-freedom motion of the capsule endoscope.
