Fig. 1 is a schematic exploded view of a capsule for endoscopic gastrointestinal tract according to a first embodiment of the present invention, and fig. 2 is a schematic structural view of the capsule for endoscopic tract and an external magnetic field in fig. 1.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a gastrointestinal endoscopy capsule, which includes a capsule shell 10 and a magnet unit disposed in the capsule shell 10, wherein the magnet unit includes a first magnet 20, the first magnet 20 is rotatably disposed in the capsule shell 10, and a magnetic pole polarization direction of the magnet unit is perpendicular to a long axis of the capsule shell 10.

In the present embodiment, the direction of polarization of the magnetic poles of the first magnet 20 is perpendicular to the long axis of the capsule housing 10. Under this structure, when the endoscopic capsule is controlled by the external magnetic field generating device, the external magnetic field generating device interacts with the first magnet 20 in the endoscopic capsule, thereby driving the endoscopic capsule to move. As shown in fig. 2, the external magnetic field generating means includes a second magnet 31 and a third magnet 32, and the endoscopic capsule is located between the second magnet 31 and the third magnet 32. The second magnet 31 and the third magnet 32 have opposite magnetic poles in the same direction, and opposite magnetic poles are arranged in the same direction. Under the action of the magnetic fields generated by the second magnet 31 and the third magnet 32, when the first magnet 20 reaches a steady state, the direction of the magnetic pole polarization thereof is aligned with the direction of the magnetic pole polarization of the second magnet 31 and the third magnet 32. In one specific example shown in fig. 2, the N-pole of the second magnet 31 is oriented downward, and the S-pole of the third magnet 32 is oriented upward. When the first magnet 20 reaches a steady state in the magnetic field formed by the second magnet 31 and the third magnet 32, the N-pole of the first magnet 20 faces the S-pole of the external magnetic field generating device, that is, the S-pole of the third magnet 32; and the S-pole of the first magnet 20 faces the N-pole of the external magnetic field generating device, i.e., the N-pole of the second magnet 31.

Under this structure, when an included angle is formed between the polarization direction of the magnetic poles of the second magnet 31 and the third magnet 32 and the polarization direction of the magnetic poles of the first magnet 20, the first magnet 20 rotates relative to the capsule housing 10, so as to maintain the balance of the magnetic field and ensure the stability of the capsule housing 10.

Further, in the present embodiment, the gastrointestinal endoscopy capsule further includes functional modules disposed in the capsule housing 10, specifically including a lens assembly 40, a power module 50, a data acquisition module 60, and a wireless transmission module 70.

Preferably, the axis of rotation of the magnet unit coincides with the long axis of the capsule housing, i.e. with line b-b in fig. 2. The arrangement of the above structures may be in other forms, but the arrangement of the structures is such that the center of mass of the enteron-endoscopic capsule is formed on the axis of the long axis of the capsule housing 10, and the rotating shaft of the magnet unit passes through the center of mass of the enteron-endoscopic capsule. The structure can further prevent the capsule shell 10 from rotating around the short axis of the capsule shell, and prevent the alimentary tract endoscope capsule from rolling in a narrow tube cavity.
