When the route-exploring capsule provided by the embodiment is used, firstly, a user needs to swallow the route-exploring capsule, and after the route-exploring capsule is swallowed and enters the alimentary canal, the shell 2 keeps a relatively good state within a certain time, generally 30 hours, so as to simulate the process of a capsule endoscope in the alimentary canal; after a certain time, if the route-exploring capsule is not expelled from the body by the user, the outer shell 2 will be completely dissolved, the support part 3 is separated from the inner core 1, so that the route-exploring capsule is decomposed into at least two independent parts, and the volumes of the support part 3 and the inner core 1 are far smaller than the whole volume of the route-exploring capsule compared with the volume of the original route-exploring capsule.

It should be noted that, after the access capsule enters the alimentary canal, the outer shell 2 may be degraded within a target time, generally within 30 hours, but the outer shell 2 may still maintain the original volume and shape, and does not affect the process of simulating the capsule endoscope in the alimentary canal.

In addition, the housing 2 and the support portion 3 need to be made of materials which are nontoxic, harmless and free of side effects to human bodies.

It should be explained that, the setting of the supporting portion 3 can play the role of supporting the shell 2 to avoid the deformation thereof, and can fix the position of the inner core 1 in the shell 2, so as to avoid the influence of the shaking of the inner core 1 in the shell 2 on the use experience.

Compared with the prior art, the route exploring capsule provided by the embodiment can be decomposed after entering the alimentary canal for a certain time, and the volume of each part after decomposition is obviously smaller than that of the original route exploring capsule, so that a user can conveniently discharge the route exploring capsule, and the route exploring capsule is prevented from being detained in the body; in addition, after the shell 2 is dissolved, the volumes of the inner core 1 and the supporting part 3 are both obviously smaller than the volume before the route exploring capsule is not decomposed, so that the judgment by a doctor is facilitated, the condition whether the digestive tract of the user is detained can be judged more accurately, and the judgment accuracy is improved.

On the basis of the above embodiment, it is possible to make the trunk support 31 include at least two trunk support units 311 separated after the shell 2 is completely dissolved, and the trunk support units 311 are uniformly distributed along the circumferential direction of the core 1.

As shown in fig. 4-6, the trunk supporting units 311 are uniformly distributed on the outer periphery of the inner core 1, so that the stress on the inner core 1 in each direction is relatively uniform, which is beneficial to the stability of the inner core 1.

Preferably, all the trunk supporting units 311 may be configured as a cylindrical structure, or a combination of several spherical structures, or an ellipsoidal structure, or an irregular shape with a round surface; the trunk supporting unit 311 is designed to have a round surface, so that the friction force applied to the trunk supporting unit 311 in the alimentary canal can be effectively reduced, and the trunk supporting unit 311 can be discharged.

Preferably, the central axis of the core 1 may coincide with the central axis of the shell 2.

On the basis of the above embodiment, the end support 32 may be made to include a first end support provided at one axial end of the core 1 and a second end support provided at the other axial end of the core 1.

The arrangement of the first end support and the second end support can position the inner core 1 from two axial ends of the inner core 1, so that the inner core 1 can be arranged in the shell 2 in a central mode.

Preferably, the first end support and the second end support can be both provided with spherical structures, hemispherical structures, ellipsoidal structures or irregular shapes with round surfaces; so as to reduce the friction force of the first end support and the second end support in the digestive tract and facilitate the discharge of the first end support and the second end support.
