Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

An object of the utility model is to provide a alimentary canal scope capsule and alimentary canal scope capsule control system to avoid alimentary canal scope capsule at the narrow intracavity motion of alimentary canal, take place to wind self minor axis pivoted phenomenon.

Fig. 1 is an exploded schematic view of a capsule for endoscopic gastrointestinal tract according to a first embodiment of the present invention, and fig. 2 is a schematic view of the capsule for endoscopic tract and an external magnetic field shown 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 rotation axis of the magnet unit is perpendicular to a long axis direction of the capsule shell 10. I.e. the axis of rotation of the magnet unit is perpendicular to the direction of extension of the b-b axis in fig. 2.

In the present embodiment, the first magnet 20 is rotatably disposed in the capsule housing 10, and the rotation axis of the magnet unit is perpendicular to the long axis direction of the capsule housing 10. When the endoscope capsule is controlled by the external magnetic field generating device, the external magnetic field generating device interacts with the first magnet 20 in the endoscope capsule, so as to drive the endoscope capsule to move in the cavity. As shown in fig. 2, the 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. As shown in fig. 2A, the external magnetic field is set such that the respective magnetic pole polarization directions of the second magnet 31 and the third magnet 32 are parallel in the horizontal direction and the magnetic pole polarization directions thereof are the same. The magnetic pole polarization direction of first magnet 20 is parallel to the magnetic pole polarization direction of second magnet 31 and third magnet 32, but the magnetic pole polarization direction of first magnet 20 is opposite to the magnetic pole polarization direction of second magnet 31 and third magnet 32, due to the magnetic field generated by second magnet 31 and third magnet 32. That is, as shown in fig. 2A, in a specific example, the N poles of second magnet 31 and third magnet 32 face the left side of the paper surface in the horizontal direction, and when first magnet 20 reaches a steady state in the magnetic field formed by second magnet 31 and third magnet 32, the N poles face the right side of the paper surface. Of course, the setting of the external magnetic field is not limited thereto.

Since the rotation axis of the magnet unit is perpendicular to the long axis direction of the capsule case 10. When the endoscopic capsule enters a narrow lumen (such as an esophagus or an intestinal tract) of the alimentary tract, and the narrow lumen inner wall presses the capsule shell 10 to move the endoscopic capsule, as shown in fig. 2B, the first magnet 20 rotates around the rotating shaft of the magnet unit under the action of the external magnetic field to achieve a relatively stable state. Therefore, the endoscope capsule can be ensured to move in the narrow tube cavity, and the overall orientation of the endoscope capsule can not be changed under the influence of an external magnetic field. Namely, the endoscope capsule can basically keep the posture of entering the narrow tube cavity to traverse the narrow tube cavity.

Therefore, under the above structure, when the endoscopic capsule moves in the narrow lumen of the alimentary canal, under the action of the external magnetic field, the first magnet 20 in the endoscopic capsule rotates around the short axis direction of the capsule shell 10 to reach a stable state, so that the endoscopic capsule does not move around the short axis of the endoscopic capsule, namely, the device does not turn around in the narrow alimentary canal. The external magnetic control device can control the gastrointestinal endoscopy capsule more accurately, and discomfort or injury to a detected person caused by the turning of the endoscopy capsule at a narrow gastrointestinal tract can be avoided.

Further, in the present embodiment, the gastrointestinal endoscopy capsule further includes a lens assembly 40, a power module 50, a data acquisition module 60, and a wireless transmission module 70 disposed in the capsule housing 10. The lens assembly 40 is disposed at one side of the magnet unit; the power module 50, the data acquisition module 60 and the wireless transmission module 70 are disposed on the other side of the magnet unit away from the lens assembly 40.

Preferably, the axis of rotation of the magnet unit coincides with the minor axis of the capsule housing 10, i.e. the axis of rotation of the magnet unit coincides with the line a-a in fig. 2A. 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. This further prevents the capsule housing 10 from rotating about its minor axis, preventing the endoscopic capsule from rolling over in the narrow lumen.
