Does the pain of a gastroscope have anything to do with the machine used for the gastroscope? Are different gastroscope brands and models (i.e. size and thickness) the same? Is there a difference in pain?

When the class contacted the endoscope, the beginning of the operation is really like catching fish, can not feel the direction of the playing angle, after skillful general patients and there is no difference. As for the brand, the general hospital with imported Olympus or domestic Shanghai Aohua endoscopy, the difference is very small.
