However, if the pressure inside the body cavity becomes too high due to excessive air supply to clean the objective lens surface or due to carelessness on the part of the operator, the inner wall of the body cavity will stretch, making it difficult to observe minute changes in the mucous membrane. Not only will this be impossible, but there is also the risk of causing accidents such as damage to the inner walls of the body cavity.
