Description
Technical Field

Background
With the advent of magnetically controlled capsule endoscopes, indications for capsule endoscopes have expanded from the small intestine to the colon and even the stomach. The principle of the capsule endoscope with magnetic control is that a small permanent magnet is arranged in a capsule, and the motion of the capsule can be controlled by the change of an external magnetic field by utilizing the acting force between the magnets, so that the capsule can be controlled in vitro.
Because various components such as an image sensor, a microprocessor and the like are required to be arranged in the magnetic control capsule, the arrangement position of the permanent magnet in the capsule needs to be considered so as to avoid occupying too much space of the magnetic control capsule. Since permanent magnets are generally electrically conductive, a typical arrangement is to integrate the permanent magnet with a battery, the whole being placed in the capsule as a power source. In the arrangement mode, the battery is directly connected with the permanent magnet, the permanent magnet is directly attached to one pole of the battery by utilizing the conductivity of the permanent magnet to form series connection, and the whole body is used as a power supply to supply power to the capsule, so that the current of the circuit must pass through the permanent magnet and then flows to the circuit of the capsule.
The arrangement mode is a common mode because other processes are not needed and excessive space of the capsule endoscope is not occupied. However, the permanent magnet has certain internal resistance and is made of special materials, so that the permanent magnet cannot be made of other materials with small internal resistance, and the internal resistance of the power supply is increased. The internal resistance of the power supply directly affects the overall performance of the power supply, and the discharge capacity of the battery is weakened due to the excessive internal resistance, particularly, the battery with relatively weak stability is greatly affected, and even the capsule can not be normally powered on.
Therefore, how to reduce the influence of the permanent magnet on the battery is a technical problem that needs to be solved by those skilled in the art at present.
