Abstract

The invention discloses a capsule endoscope, which comprises a battery, a permanent magnet and a functional assembly for supplying power through the battery, wherein the permanent magnet is connectedin parallel with a connecting sheet which can conduct electricity and has an internal resistance smaller than that of the permanent magnet so as to be in short connection with the permanent magnet, one end of the connecting piece is connected with the battery and the other end of the connecting piece is connected with the functional assembly. A section of connecting piece with good conductivity isadded between the battery and the permanent magnet, the battery supplies power to a capsule circuit board through the connecting piece, the power supply performance loss caused by the conduction of the permanent magnet is avoided, the original discharge performance of the battery can be kept to the maximum extent, the influence of the permanent magnet on the battery can be reduced; meanwhile, thearrangement mode of the battery and the permanent magnet in the prior art does not need to be changed, and the battery and the permanent magnet are still connected in series, so that excessive occupied space is not increased, and the assembly space is saved while the discharge performance of the battery is kept.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a capsule endoscope. Background technique [0002] With the advent of magnetically controlled capsule endoscopy, the indications for capsule endoscopy have expanded from the small intestine to the colon and even the stomach. The principle of magnetically controlled capsule endoscopy is to place a small permanent magnet inside the capsule, and use the mutual force between the magnets to allow the movement of the capsule to be controlled by changes in the magnetic field outside the body, realizing the control of the capsule outside the body. [0003] Since the magnetically controlled capsule needs to be equipped with image sensors, microprocessors and other components, the placement of the permanent magnet inside the capsule needs to be considered to avoid occupying too much space in the magnetically controlled capsule. Since permanent magnets are generally conductive, a...
