The size of the jaws has been carefully studied and can only be bitten into the gastric mucosa without significant damage to the stomach wall. In order to make the diagnosis more accurate, it may take more than two tissues and store them in a small glass bottle containing the preservation solution. The doctors in the pathology department cut the tissue blocks into thinner sections, and processed them into stains and so on, and then made them into pathological slides, and then observed whether there were cancer, inflammation, atrophy, etc. by microscope. Not suitable for the crowd Not suitable for people: (1) Poor coagulation function. (2) People with gastric hemangioma (soft).
