Recently, the State Drug Administration reviewed and approved the NMPA registration certificate of "Endoscopic Ultrasound Systems for Gastrointestinal Endoscopy" produced by Beijing LepuImage Technology Co., Ltd. This product is composed of ultrasonic probe, probe driver, image processor, keyboard and foot switch, which can realize ultrasonic imaging of human digestive tract (including esophagus, stomach, duodenum and  colorectal) and surrounding organs.

The unique feature of this product is that it is the first time in China to apply ultrasound imaging technology to the field of lower digestive tract. It can achieve deeper tissue ultrasound imaging on the basis of conventional endoscopy, and has clinical advantages for submucous lesions of digestive tract directly less than 2cm.

Generally, the digestive tract can be divided into five layers, from the inside to the outside, which are mucosa, muscularis mucosa, submucosa, muscularis and serosa. Because conventional gastroscope and enteroscope are visible light imaging, they can only observe the digestive tract mucosa and the surface of lesions in the lumen of the digestive tract. Endoscopic ultrasound combines endoscopy with ultrasound, and places the ultrasound probe at the front end of the endoscope (gastroscope and colonoscope) or introduces the miniature ultrasound probe through the endoscope to observe the morphology of lesions on the surface of the mucosa through the endoscope, Ultrasound scanning can clearly show the tissue structure of each layer of the digestive tract wall and the benign and malignant lesions of the surrounding organs (esophagus, mediastinum, stomach, duodenum, pancreaticobiliary system, adrenal gland, etc.).

With the popularization of Huaco miniature probe equipment in medical institutions at all levels, it will provide convenience for the early detection and treatment of digestive tract diseases in the future. The listing of domestic ultrasound endoscope will also reduce the burden of patients' comprehensive costs, enrich the means of doctors' diagnosis and treatment, and play an important role in improving the convenience of doctors' operation and saving the pressure of social medical insurance funds.
