Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a wire-hanging assisted magnetically controlled capsule magnifying chromoendoscopy. Background Art

[0002] "Capsule endoscopy" is the abbreviation of medical wireless endoscopy system. It is a new type of non-invasive and painless digestive tract and intestinal wireless detection system. It consists of a pill-shaped capsule that realizes the digestive tract detection function and an in vitro image recorder. Due to the use of micro-optical electromechanical technology, the size of the smart endoscope is very small. Patients do not need anesthesia and can move freely during the swallowing process, eliminating the pain and inconvenience caused by traditional detection methods. As this technology contains huge commercial benefits and application prospects, and has the advantages of simple operation, painless, and no cross infection, capsule endoscopy is favored by more and more researchers at home and abroad. However, clinical experiments have shown that there are still some technical problems in capsule endoscopy that need to be solved.

[0003] Due to the complex environment inside the small intestine, the capsule endoscope in the prior art is very likely to roll over when it is running in the intestine, which affects the working performance of the capsule endoscope and sometimes even causes the capsule endoscope to get stuck in the intestine. The capsule endoscope in the prior art often relies on the peristalsis of the intestine to move forward and has no self-driving ability. At present, the hanging wire capsule endoscope can only perform white light inspection and cannot perform staining inspection to further improve the screening accuracy. Therefore, it is necessary to invent a hanging wire-assisted magnetically controlled capsule magnified staining endoscope to solve the above problems. Summary of the invention
