The doctor has good skills and the patient feels much more comfortable.
This shows that comfortable technology is by no means easy to achieve.
Assistant Jiang's live broadcast was interrupted, and his eyes were glued to the screen to watch the operation. There was no other way. He couldn't see anything if he turned back to observe the operation of Chief Surgeon Xie. It would be more reliable to look at the display on the machine screen.
Doctor Cao Zhao, who was waiting on the other side, could not bear it any longer and complained to Assistant Jiang: "You don't need to study it carefully, you can't figure it out. Just tell us what you can see, and let our brains think better instead of yours."
Assistant Jiang: At least I am a specialist doctor.
General surgeons do not perform colonoscopies in their daily work, but that does not mean they have never come into contact with colonoscopies or are completely unable to understand them.
The reason why we "can't understand" Dr. Xie's manual operation is that the development of colonoscopy technology over the years has formed a set of effective conventional operating techniques in the industry, which sounds easy but is difficult to do.
That is, I understand what Dr. Xie is doing with this manual exercise, but I don’t understand how Dr. Xie can achieve such perfect and miraculous results.
To be more specific, the main part examined by colonoscopy is the colon, which is 1.7 to 2 meters long. According to the length of colonoscope we mentioned earlier, the two are not of equal length, so it should be difficult to reach the innermost examination area.

This is the first problem. The second problem is that colonoscopy and gastroscopy are different. Many doctors who are very good at performing gastroscopy think that the two examination tools are similar. They want to directly transfer the gastroscopic techniques to colonoscopy, but they immediately fall flat on their face.
The intestine and stomach of the human body are two different organs, with different shapes, functions and even different positions. Textbooks say a lot of these, but none of them can give people a good understanding of the actual medical practice.
To sum it up in one sentence, if you take it for granted that a colonoscope is a gastroscope, it is easy for the intestine to quickly coil into a ball called a loop after entering the intestine, and it will be unable to move forward or backward.
The patient's intestines are alive, and their anatomical shape is very similar to a movable spiral tube. After the soft body of the colonoscope enters the intestine, the intestine feels that the colonoscope is making movements similar to pushing stool on a daily basis. This spontaneous "resistance movement" of the human body can easily cause the colonoscope operator to lose control and become tangled.
How can a gastroscope not do this? A gastroscope is not like the intestinal tube, which is twisted and turned. Its almost straight structure does not give the soft endoscope a chance to twist after entering.
It is not true to say that the operations of gastroscopy and colonoscopy are completely different and have no similarities. As mentioned before, the basic operations of these types of examinations and surgeries are similar.
Like gastroscopy and colonoscopy, they also need to be inflated to expand the folds, so controlling the amount of gas is one of the technical tricks.
How the operator can grasp the essence of the difference between small differences ultimately depends on the basis of anatomy. Inflating during colonoscopy will cause the intestine to be inflated and accelerate intestinal peristalsis. In addition, the intestines of some people are very sensitive to inflation, so the timing of inflation is different from that of gastroscopy.
Assistant Jiang said a lot of things, meaning that I couldn't be a specialist doctor who knew nothing. I could see that what Dr. Xie was doing now were basic colonoscopy operations such as rotating the mirror, pulling it back into position, shaking the mirror and injecting water. He even understood the axis-keeping and retraction method in the introductory technique of the divine operation recommended by colonoscopy.
In order to allow the operator to freely control the inspection movement of the colonoscope in the intestinal cavity, a method invented by clinical predecessors: after the colonoscope enters the intestine, it keeps the axis consistent with the movement of the intestine, allowing the intestine to automatically fit over the body of the scope, shortening the intestine to reach the deepest inspection site, and then perfectly solving the first and second problems mentioned above.
As for when to rotate left or right, and when to press the wrinkles on the inner wall of the intestine to hook and shrink the tube, these are the practical experience of doctors. It is one thing to say and another to do.
Assistant Jiang further expressed the profound meaning: You won’t understand even if I tell you, so just marvel with me.
As he spoke, Assistant Jiang once again stared at the screen in silence, watching as Chief Surgeon Xie suddenly performed a magical operation in front of him and successfully pulled down the mirror and retracted the tube.
This operation may not be considered a miracle under normal circumstances, but it must be considered a miracle now because the timing was just right: the operating vehicle was starting up with momentum.
All we can say is that it is possible that Dr. Xie used the operating cart as his own "surgical assist tool", otherwise there is no explanation.
Really?
