In this embodiment, the light-transmitting film 30 has good light-transmitting properties, so that the lens in the capsule endoscope 10 can clearly capture images. And the light-transmitting film 30 also has the characteristic of biocompatibility, can be directly exposed in internal organs of a human body for use, and ensures the healthy use of a patient.

By covering the outer surface of the front shell 13 of the capsule endoscope 10 with the light-transmitting film 30, the surface of the front shell 13 can be effectively protected in the recovery process after the capsule endoscope 10 is released, so that the imaging effect is prevented from being influenced by abrasion, and the service life of the capsule endoscope 10 is prolonged.

Moreover, even if the light-transmitting film 30 is damaged after a long-term use or when the capsule endoscope 10 is sterilized, the light-transmitting film 30 can be peeled off and re-coated without damaging the capsule endoscope 10, thereby reducing the use cost of the endoscope apparatus when it is recycled.

Further, a detection layer 40 is provided between the capsule endoscope 10 and the light-transmitting film 30. In the present embodiment, in order to ensure the sealing performance between the light-transmitting film 30 and the capsule endoscope 10, the detection layer 40 may be coated on the surface of the capsule endoscope 10, and then the light-transmitting film 30 may be coated. The arrangement of the detection layer 40 is convenient for detecting the sealing performance of the light-transmitting film 30 covering the capsule endoscope 10, so that the light-transmitting film 30 and the capsule endoscope 10 are well sealed after the capsule endoscope 10 is recovered and disinfected or after the capsule endoscope 10 is coated with the film again, and then the cross infection caused by poor sealing performance of the light-transmitting film 30 when the capsule endoscope 10 is repeatedly used is avoided.

Specifically, the detection layer 40 may be made of a transparent material. When the capsule endoscope 10 after film covering is put into the detection liquid, and the sealing performance of the light-transmitting film 30 is good, the color of the detection layer 40 on the capsule endoscope 10 cannot change; on the contrary, when the sealing performance of the light-transmitting film 30 is not good, the detection liquid enters the light-transmitting film 30 and contacts the detection layer 40, and the detection layer 40 on the capsule endoscope 10 changes in color, so that the detection person can clearly know that the light-transmitting film 30 is damaged or has poor sealing performance.

In addition, in order to further protect the outer surface of the capsule endoscope 10, the capsule endoscope 10 can be directly sterilized after the capsule endoscope 10 is recovered, and the light-transmitting film 30 is torn off after the sterilization is completed, and the detection layer 40 is coated again, so that the outer surface of the capsule endoscope 10 is prevented from being directly sterilized to cause abrasion or damage to the outer surface of the capsule endoscope 10. In addition, cross-infection of the next patient by residual body fluid or germs on the outer surface of the capsule endoscope 10 during sterilization can be avoided.

Specifically, the light-transmitting film 30 covers the outer surfaces of the front housing 13 and the rear housing 11, and the detection layer 40 is disposed on the outer surface of the front housing 13 and/or the rear housing 11.
