”Capsule Endoscopy” is called “Intelligent Capsule Gastrointestinal Endoscopy System”, also known as “Medical Wireless Endoscopy”. Its working principle is: the subject takes the intelligent capsule with built-in camera and signal transmission device orally, and moves in the digestive tract with the help of digestive tract peristalsis and takes images, and the doctor uses the image recorder and imaging workstation outside the body to understand the whole digestive tract situation of the subject, so as to make a diagnosis of his condition. Capsule endoscopy has the advantages of convenient examination, no trauma, no wires, no pain, no cross-infection, and does not affect the normal work of the patient, etc. It expands the field of view of the gastrointestinal tract examination and overcomes the defects of the traditional insertion endoscopy such as poor tolerance, not suitable for the old and weak and critical conditions, and can be used as the first choice for the diagnosis of gastrointestinal diseases, especially small intestinal diseases, and is called the revolution and direction of endoscopy development in the 21st century. It has been called the revolution and direction of endoscopy in the 21st century. The birth of capsule endoscopy is a major breakthrough for the blind area of small intestine, and also enables the early diagnosis of gastrointestinal diseases. There is an old Chinese saying that “prevention is better than cure”. However, to achieve this in clinical practice, advanced, safe and comfortable medical devices are needed. The OMOM capsule endoscopy is a new, safe and comfortable means of examining the digestive tract, which eliminates the patient’s fear and rejection of the examination. This makes OMOM capsule endoscopy an important application for early diagnosis of gastrointestinal diseases. The clinical application of OMOM capsule endoscopy has shown that, in addition to some patients who undergo the examination because of their illness, more than half of the examinees are of a physical examination nature. It proves that capsule endoscopy also has broader application space in physical examination. With the improvement of people’s quality of life, the pursuit of health has become a necessity. If OMOM capsule endoscopy can be vigorously applied in medical checkups, it is expected that the late incidence of digestive tract diseases in the nation will be greatly reduced.
