Embodiment 1

[0023] Such as figure 2 with image 3 As shown, the present invention provides a retractable capsule endoscope, including an image capture module, a capture control and image processing module 3, a power supply module 4 (in this embodiment, 2 button batteries) and The wireless transmission module, the housing includes a transparent first housing 11, a non-transparent second housing 12 and a retractable third housing 13, and the image capture module is arranged close to the first housing The end of 11 is made up of LED light source 23 , image sensor 21 and lens 22 .

[0024] When the capsule endoscope enters the human digestive tract, it will wriggle from top to bottom under the action of gravity. The third shell 13 is an annular corrugated segment structure, embedded in the second shell 12, when the capsule endoscope is squeezed, the third shell 13 can shrink, and the total length of the capsule endoscope will shrink. For better airtightness, a preferred embodiment is that...

Embodiment 2

[0027] Such as Figure 4 with Figure 5 As shown, compared with Embodiment 1, in order to avoid taking worthless failure images out of control of the direction and angle of the capsule in the body, a permanent magnet 9 is usually arranged in the housing near the end of the second housing 12 for The direction of movement and the angle of rotation of the capsule endoscope are guided by an external magnetic field.

[0028] Preferably, the weight of the permanent magnet 9 should be greater than the sum of the weights of other components in the casing, so that the capsule endoscope can keep vertical movement as much as possible under the action of gravity. The doctor can also use the external magnetic field to correct the shooting angle of the capsule through the magnetic force of the permanent magnet 9 (such as Figure 5 As shown, the shooting angle can be raised by pulling down the permanent magnet 9), thereby greatly improving the quality and efficiency of taking pictures.

Abstract

The invention provides a telescopic capsule endoscope. The telescopic capsule endoscope comprises an image shooting module, a shooting control and picture processing module, a power supply module and a wireless transmission module, wherein the image shooting module, the shooting control and picture processing module, the power supply module and the wireless transmission module are arranged in an airtight shell. The shell comprises a transparent first shell, a non-transparent second shell and a telescopic third shell. The image shooting module is arranged close to the end of the first shell and composed of an LED light source, an image sensor and a lens. The third shell is of an annular corrugated section structure. The telescopic capsule endoscope can solve the problem that a capsule endoscope is stuck in the alimentary canal; besides, the shooting angle can be finely adjusted to improve the image shooting quality.

Description

technical field [0001] The invention relates to the technical field of capsule endoscopes, in particular to a retractable capsule endoscope. Background technique [0002] Such as figure 1 As shown, in order to non-invasively examine the body cavity organs in animals or humans, especially the body cavity of the digestive tract, swallowing capsule endoscopes are currently used to obtain in vivo information of the subject. The volume of the capsule endoscope is usually less than 11×26mm. The person to be tested swallows the capsule endoscope from the oral cavity. After the capsule endoscope enters the body, it moves with the peristalsis of the organs (such as the stomach, intestinal tract), and finally passes through the body. During this period, the capsule endoscope sequentially acquires the information of each organ, and sends the acquired information to the information receiving and processing device outside the body through wireless communication to complete the entire de...
