摘要： A system for guiding capsule medical device includes a capsule medical device that includes a capsule casing including an imaging unit and a permanent magnet magnetized in a direction relatively fixed with respect to an upward and downward direction of an imaging surface of the imaging unit. The capsule medical device has a center of gravity deviated from a geometric center of the casing toward a direction different from a magnetization direction of the permanent magnetic. In the capsule medical device, a plane parallel to the imaging surface and a plane parallel to the magnetization direction and a deviation direction of the center of gravity with respect to the geometric center form an intersection line. The system further includes a magnetic guidance device; and an image display device displaying an in-vivo image such that a direction of the intersection line conforms to an upward and downward direction of a screen.

摘要： A medical apparatus has an insertion unit inserted in the body cavity of the living body. A position/posture detecting unit detects at least one of the position and the posture of the insertion unit. Magnetic field generating units are arranged in an axisymmetrical manner on the substantially plane, and includes at least three electromagnets having magnetizing directions substantially orthogonal to the plane. A magnetic field control unit controls a magnetic field generated by the magnetic field generating unit. A position/posture varying unit varies a relative position/posture between the magnetic field generating unit and the insertion unit in accordance with position and posture information of the insertion unit obtained by the position/posture detecting unit. The magnetic field control unit controls the magnetic field generated by the magnetic field generating unit that is applied to a magnetic field operated unit arranged to the insertion unit, thereby guiding the medical apparatus.

摘要： In a capsule 3 as a medical apparatus inserted into a body cavity, the lengthwise direction of the capsule 3 is used as an insert axis, a manipulation/input device 8, which is magnetized in a direction orthogonal to the insert axis, is disposed at the center position of the insert axis. A magnetic field generation device 4, which is disposed outside of a body, is caused to generate a vibration magnetic field in a direction parallel with the insert axis of the capsule 3 by turning on a vibration (ON/OFF) switch 8f of a manipulation/input device 8 so that couples having lines of action, which are in parallel with the insert axis, are exerted on the capsule 3, thereby the capsule 3 executes a swiveling motion about the insert axis and smoothly travels along a cavity organ.
