    • A coil system for the contact-free magnetic navigation of a magnetic body with a magnetic dipole moment in a working chamber, a number of coils and a current control unit for controlling the respective currents in the multiple coils. The current control unit generates a force on the magnetic body in a predefined direction by setting the currents in the multiple coils so that the direction of the force generated by the currents on the magnetic body at each position among a number of positions in a volume in the working chamber essentially corresponds to the predefined direction of force. This coil system has the advantage that the position of the magnetic body in the working chamber does not need to be known exactly in order to move the body in a desired direction or to align the body in a desired orientation direction. This coil system suitable for use in a medical device and by special preference in a device for capsule endoscopy. In this situation, the magnetic body is a capsule that can be navigated in the body of a patient and has an imaging system for capturing images of the internal organs of the patient and a transmit module for sending the captured images to a receiver.
    • 一种线圈系统,用于在工作室中具有磁偶极矩的磁体的无接触磁导航,多个线圈和用于控制多个线圈中的相应电流的电流控制单元。 电流控制单元通过将多个线圈中的电流设定为在多个线圈中的电流而在磁体上产生的力在预定方向上产生的力, 工作室基本上对应于预定的力方向。 该线圈系统的优点在于,不需要精确地知道工作室中的磁体的位置,以便使身体沿期望的方向移动或使身体在期望的取向方向上对准。 该线圈系统适用于医疗装置,特别优选用于胶囊内窥镜检查装置。 在这种情况下,磁体是可以在患者体内导航的胶囊,并且具有用于拍摄患者内脏的图像的成像系统和用于将拍摄图像发送到接收器的发射模块。

    • 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.
