摘要:
An endoscopy capsule contains an induction coil that is elongated along a longitudinal axis thereof, the endoscopy coil supplying power to components within the endoscopy capsule. A magnetic element in the endoscopy capsule has a magnetic dipole moment and interacts with an external magnetic field to navigate the endoscopy capsule within the body of a subject. The magnetic element is oriented so that the magnetic dipole element is aligned perpendicularly to the longitudinal axis of the induction coil. The endoscopy capsule has a cross-sectional area, in a plane having a normal aligned in the direction of the longitudinal axis of the induction coil, which contains both a cross-section through the magnetic element and a cross-section through the induction coil. The magnetic element has a length along the longitudinal axis of the induction coil so that the magnetic element projects beyond the induction coil at each end thereof.
