A capsule medical apparatus includes a tissue obtaining unit that obtains a tissue from a body site of a subject; a detecting unit that detects a state of the tissue obtaining unit that varies depending on whether the tissue obtaining unit succeeds in obtaining a tissue; an output unit that outputs information representing whether the tissue obtaining unit succeeds in obtaining a tissue; and a control unit that determines whether the tissue obtaining unit succeeds in obtaining a tissue based on the state of the tissue obtaining unit, which is detected by the detecting unit, and causes the output unit to output the information representing whether the tissue obtaining unit succeeds in obtaining a tissue.

Capsule medical apparatus and medical system

An encapsulated medical device guidance system, and a method of controlling the system, in which a magnetic generator acts on a magnet built into a capsulated medical device, and generates a magnetic field for controlling the position and/or posture of the capsulated medical device, and a control unit has a dynamic torque estimation unit to estimate a dynamic torque to be applied to the encapsulated medical device in a target posture, controls a magnetic field generated from the magnetic field generator so that a magnetic torque generated by the magnetic field generator becomes proportional to a dynamic torque estimated by the dynamic torque estimation unit, and controls the posture of a capsule endoscope by considering gravity applied to the capsule endoscope itself.

Encapsulated medical device guidance system, and a method of controlling the same

An object of the present invention is to actively control at least one of the position and direction of the imaging field in a subject and to observe a desired observed region in the subject certainly in a short period of time. A body-insertable device system according to the present invention includes a capsule endoscopeintroduced into a subject and a permanent magnet. An imaging unit of the capsule endoscopefor taking an image inside the subject is fixed in a casing. The capsule endoscopeincludes a drive unit for changing at least one of the position and posture of the casing in the liquidwhich is also introduced in the subject. The permanent magnetcontrols the operation of the drive unit for changing at least one of the position and posture of the casing in the liquid

Body-insertable device system and in-vivo observation method

An intra-subject observation system includes a first liquid inserted into a desired organ of a subject; and a second liquid inserted into the organ without being mixed with the first liquid due to a specific gravity lighter than that of the first liquid. The system also includes a capsule medical apparatus inserted into the organ with an intermediate specific gravity between the specific gravity of the first liquid and that of the second liquid to acquire intra-subject information, which is output out of the subject by radio.

Body-insertable device positioning system and in-vivo observation method

A medical system includes: a medical device to be inserted into the body cavity; a rotating device for the medical device for rotating the medical device around the insertion axis; an image pickup device provided to the medical device; and an image capturing timing detection device for detecting a signal regarding image capturing timing performed by the image pickup device. Furthermore, the medical system includes: a rotating angle acquisition device for acquiring the rotating angle of the rotating device for the medical device regarding the image capturing timing in response to the output of the image capturing timing detection device; and an image acquisition device for performing rotation processing for the image captured by the image pickup device based upon the information regarding the rotating angle acquired by the rotating angle acquisition device, thereby acquiring the image subjected to a rotation processing.

Medical system

A detecting system of the position and the posture of a capsule medical device includes a main body of the capsule medical device that is inserted in a living body, a coil in a capsule that is arranged to the main body of the capsule medical device and forms a resonant circuit, a magnetic field generating device that is arranged around the living body and generates the Alternating magnetic field for generating an induced magnetic field in the coil in the capsule, and a plurality of magnetic field detecting devices that detect the strength of the induced magnetic field generated by the coil in the capsule by the magnetic field generated by the magnetic field generating device.
