[0002] When children experience gastrointestinal discomfort, a gastroscopy is generally required to identify the specific cause. Gastroscopy is the preferred examination method for upper gastrointestinal tract lesions. It can directly observe lesions in the esophagus, stomach and duodenum, and perform pathological biopsy on suspicious lesions.

[0003] In the prior art, a gastroscope generally includes a main unit and a peep probe connected to the main unit via a catheter. However, for children, their esophagus is narrow and sensitive. When a relatively thick catheter is inserted into the esophagus of a child, it will cause strong discomfort, making the examination impossible. Summary of the invention
