Description

Technical Field

[0001] The present invention relates to the field of capsule endoscope treatment, and particularly to an auxiliary treatment device based on a digestive tract capsule endoscope. Background Art

[0002] Since the capsule endoscope (or capsule endoscopy) was approved by the US Food and Drug Administration for the examination of small intestine diseases in 2001, the capsule endoscope has been favored by doctors and patients for its characteristics of simple operation, convenience, painlessness, non-invasiveness, and safety. By 2009, more than 750,000 people had received capsule endoscopy. Currently, the capsule endoscope is mainly used for the diagnosis of diseases such as obscure gastrointestinal bleeding, Crohn's disease, and small intestine tumors. In recent years, due to the development of technology, capsule endoscopes for examining the esophagus and colon have gradually emerged, and the application scope of the capsule endoscope has been further expanded, providing great help to gastroenterologists.

[0003] Currently, the existing capsule endoscope can only take pictures in one direction, resulting in inaccurate positioning of the injured parts of the digestive tract. Moreover, because there are various liquids in the digestive tract, it is easy to affect the shooting effect of the camera, and the effect of spraying drugs through the capsule endoscope is also very unsatisfactory, and the effect of fixing the capsule endoscope in the digestive tract is also very unsatisfactory. Therefore, a capsule endoscope that can adapt to auxiliary treatment in the digestive tract is very necessary. Summary of the Invention

[0028] The specific implementation method is as follows: The patient swallows the device into the digestive tract. At this time, the lower capsule cover 501 is in a closed state. The soft protection member 2001 of the buffer protection structure 20 protects the patient's digestive tract. The first camera structure 6 takes pictures of the patient's digestive tract. The illuminating lamp 16 provides illumination. The positioning of the capsule endoscope is realized through the mutual magnetic action between the external magnetic device and the positioning magnet 902. When approaching the injured digestive tract, the driving motor 704 drives the central driving shaft 703 to drive the lower capsule driving shaft 502 to extend, thereby driving the lower capsule cover 501 to open, and driving the rack shaft section 702 and the support shaft section 701 to extend, realizing the fixation of the capsule endoscope in the digestive tract.

Then, the driving motor 704 is driven to contract the rack shaft section 702, the support shaft section 701, and the lower capsule driving shaft 502, thereby driving the lower capsule cover 501 to contract, reducing the volume of the capsule endoscope to the smallest, and discharging it from the human digestive tract, realizing the auxiliary treatment process of the capsule endoscope.

[0029] The beneficial effects of the present invention are embodied in that: through three different structural layers, the present invention realizes the functions of capsule endoscope fixation, first camera function, second camera function, magnetic pole positioning function and drug spraying function respectively; the motor is used to drive a plurality of rack shaft segments and support shaft segments to fix the capsule endoscope in the patient's digestive tract. The contact end of the support shaft segment with the digestive tract is arc-shaped, which can better protect the inner wall of the patient's digestive tract and is more stable than the single-layer fixation structure in the prior art; through the lower capsule cover structure that can be freely opened, double fixation of the capsule endoscope is realized, and the second camera is protected, enabling the second camera to take clearer pictures. The second camera structure that can be freely telescoped can meet the more comprehensive digestive tract shooting task; through a special drug spraying structure, uniform spraying of the drug is realized, and a buffer protection structure arranged at intervals is adopted, which not only plays a role in buffering and protecting the digestive tract, but also enables the liquid medicine sprayed by the drug spraying structure to stay at the digestive tract wound for a longer time, which is more conducive to the absorption of the digestive tract.
