Capsule colonoscopy is carried out with intestinal peristalsis, because it can't be controlled, it is likely to miss the diagnosis. Han An's "Magnetic Capsule Gastroscope" robot can collect images of the stomach in strict order of fundus, cardia, body, angle, antrum and pylorus, which ensures the accuracy, completeness and systematicness of the examination.

20 15 Han An "magnetic capsule gastroscope" robot and clinical "gold standard" electronic gastroscope carried out a large sample, multi-center, double-blind controlled clinical experiment. The experimental results fully prove the high consistency between magnetic capsule gastroscope and electronic gastroscope in the diagnosis of gastric diseases. Research papers and data were published in CGH, the official academic journal of American Digestion Association (AGA).

In fact, it has been highly recognized by the international academic community.
