The capsule endoscope is generally in a capsule shape, two ends of the capsule endoscope are arc-shaped, and images shot from the inside of a human body are transmitted to the outside of the capsule endoscope through the image acquisition module so as to realize medical diagnosis on the inside of the human body.

A capsule endoscope of the present invention is described below with reference to fig. 1 to 4, including: a housing 10 and an image acquisition module.

Wherein, the top of casing 10 is equipped with the transparent window, and the bottom of casing 10 has the arc surface, and casing 10 has the axis b that extends from the top of casing 10 to the bottom. The casing 10 is the external shape structure of the capsule endoscope, is in a capsule shape, and is convenient to take down, and a mounting cavity formed in the casing can be used for mounting electric elements so as to realize corresponding diagnosis functions.

Specifically, casing 10 includes upper cover 11 and inferior valve 12, and upper cover 11 is the transparence, and the transparent window is formed at upper cover 11, and the arc surface is located inferior valve 12 and keeps away from the bottom surface of upper cover 11, and upper cover 11 and inferior valve 12 are connected to enclose and close the cavity that is formed with the installation image acquisition module. The upper cover 11 and the lower cover 12 can be bonded by means of glue or laser welding to seal the inner cavity and prevent liquid from entering. Since the upper cover 11 is transparent, the whole can be regarded as the transparent window. Further, the upper cover 11 has a first cavity facing the lower shell 12, and the image capturing module is disposed in the first cavity. Locate the image acquisition module in the first cavity to realize internal shooting through camera lens 21, and camera lens 21 can not be because of the opaque face causes shoots sheltering from. In addition, the lower case 12 has a second cavity facing the upper cover 11.

In addition, the image acquisition module is arranged in the shell 10, the image acquisition module comprises a lens 21, and the lens 21 faces the transparent window; the specific gravity of the capsule endoscope is greater than that of the submerged liquid, the center of gravity a of the capsule endoscope is deviated from the central axis b, and the center of gravity a of the capsule endoscope is located at a position close to the bottom of the housing 10.

The lens 21 can shoot an image in the body through the transparent window to facilitate medical diagnosis.

Here, the specific gravity of capsule endoscope is greater than the liquid that sinks, means that the capsule is after placing in the liquid, and gravity is greater than buoyancy, sinks to laminating body wall, can ensure the stable shooting of image acquisition module. Optionally, the liquid is water, which of course, in the case of the human body, may also be physiological saline, the weight of the capsule endoscope being dependent on the particular submerged liquid.

Referring to fig. 2, the center of gravity a of the capsule endoscope is offset from the central axis b and is close to the bottom of the housing 10, so that the capsule endoscope is inclined from the bottom of the liquid after being immersed in the liquid. Specifically, a connecting line of the floating center and the gravity center a of the capsule endoscope passes through the arc surface. At this time, the position of the arc surface through which the connecting line of the floating center and the gravity center a passes is the supporting point when the capsule endoscope and the liquid bottom are obliquely arranged. In addition, along with shaking under different conditions, the capsule endoscope can move in a tumbler shape and finally return to the inclined arrangement posture.

In this embodiment, because the center of gravity a of the capsule endoscope deviates from the central axis b and is close to the bottom of the housing 10, the capsule endoscope can be obliquely arranged at the bottom of the liquid, when the patient adjusts different body positions, the capsule endoscope can present the movement of the tumbler shape, the top of the capsule endoscope can face different directions, and then the lens 21 can shoot towards different positions, so that the all-round shooting in the human body can be realized.
