The so-called "gastroscope that can be eaten into the stomach" is the "intelligent capsule digestive endoscopy system", also known as "medical wireless endoscope", referred to as "capsule endoscope". In fact, it is a small robot that can emit radio waves. After entering the human body, it can move downward with the natural peristalsis of the digestive tract, shoot ** while walking, and constantly upload ** to the image recorder outside the body, so that the doctor can easily understand the situation of the entire digestive tract and make a diagnosis of its condition. Capsule endoscopy is very convenient for the elderly and is one of the best ways to see if there is a problem with the crooked small intestine.
The world's first capsule gastroscope was successfully manufactured in Israel in 2001 and entered clinical use. Capsule gastroscopy is an important development in gastrointestinal endoscopy. Later, the medical community created capsules that can be loaded with drugs for remote release in the digestive tract, capsules that can sample the patient's digestive tract tissue according to medical needs, and various other capsules with specific functions.
Compared with traditional gastrointestinal endoscopy, the main advantages of capsule endoscopy are: it expands the doctor's field of vision, can take color images of the whole small intestine, and breaks through the blind spot of small intestine examinationSafe and hygienic, all capsules are disposable, and the shell is made of corrosion-resistant medical high materials, which are non-toxic and non-irritatingComfortable and comfortable for patients without having to endure the pain of routine gastrointestinal endoscopic intubation.
However, capsule endoscopy also has disadvantages: first of all, it is expensiveSecondly, the image positioning is not as intuitive and clear as the conventional gastroscope, and it needs to be confirmed with the computer positioning system. In addition, for those with digestive tract malformations, the capsule may "go astray";In patients with pacemaker implantation, the capsule signal will be interfered with;In patients with enteritis, the capsule may become lodged in the intestine, so none of the above patients are suitable for capsule examination.
