Abstract
A capsule endoscope according to one embodiment includes: a camera; a transceiver; a tubular receiving coil for receiving power supplied from an external power transmitting antenna via magnetic flux; a tubular capsule accommodating these components; and an X-ray marker to be used in location and orientation detection. In the capsule endoscope, a magnetic body is arranged along the inner periphery of the receiving coil, and a self-propelling drive device including an electromagnet and a permanent magnet is arranged in series with the receiving coil along the tubular axial direction of the capsule so that the permanent magnet does not enter the inside of the receiving coil.
Claims16
A generally cylindrical capsule endoscope to be used for diagnosing the condition of the inside of a tubular organ such as a digestive tract by going into the tubular organ, the capsule endoscope including:
- a camera which shoots the inside of the tubular organ;
- a transceiver which performs a wireless communication with the outside;
- a cylindrical power-reception coil which receives power that is supplied from an external power-transmission antenna via a magnetic flux;
- a self-propulsion drive device which causes the capsule endoscope to move along the inside of the tubular organ;
- and
- a generally cylindrical capsule which houses the above components,
- wherein a magnetic body is disposed adjoining an inner circumferential surface of the power-reception coil,
- wherein the self-propulsion drive device has a coil and a magnet, and
- wherein the self-propulsion drive device is disposed in series to the power-reception coil in an axial direction of the capsule so as not to be located inside the power-reception coil.
(canceled)
A capsule endoscope examination instrument which uses
- a capsule endoscope including:
- a camera which shoots the inside of a tubular organ;
- a transceiver which performs a wireless communication with the outside;
- a cylindrical power-reception coil which receives power that is supplied from an external power-transmission antenna via a magnetic flux;
- a self-propulsion drive device which causes the capsule endoscope to move along the inside of the tubular organ;
- and
- a generally cylindrical capsule which houses the above components,
- wherein a magnetic body is disposed adjoining an inner circumferential surface of the power-reception coil,
- wherein the self-propulsion drive device has an electromagnet and a permanent magnet, and
- wherein the self-propulsion drive device is disposed in series to the power-reception coil in an axial direction of the capsule so that the permanent magnet is not located inside the power-reception coil,
- the capsule endoscope examination instrument including:
- the capsule endoscope;
- and
- a power-transmission antenna or antennas which supply power wirelessly to the power-reception coil of the capsule endoscope,
- wherein the power-reception coil comprises a cylindrical coil, and
- wherein the power-transmission antenna or antennas are ones formed by winding a conductor into a planar spiral.
