I saw some people asking questions on the platform, saying that if doctors are now looking at films to treat diseases, then what do we need doctors for? If you want to see a doctor, you have to register first, then the doctor orders a test, and after the test, you have to register again and then give the film to the doctor. But the imaging doctor has issued the report, and then why go to the doctor again to register? In particular, these doctors do not visit every day, often a small disease let me run two or three times, the final result is nothing. Some patients even suspect that the doctor’s list is to generate revenue, the more tests the doctor prescribes, the higher the salary commission will be given. This problem is actually a mutual understanding of the perception of the problem. Some people say, you see Chinese medicine is to look, smell and cut, based on experience to see, but if you have a field visit to the larger local general Chinese medicine hospital, you will find that the Chinese medicine examination program is also a lot. In fact, whether it’s Chinese medicine or Western medicine, they all rely on their own knowledge and experience in medicine to see the disease, and the examination is a supplement to the experience of guessing, to confirm whether their guesses are correct. If a doctor looks at you and tells you what disease you have, do you think this doctor is reliable? If you don’t use the instrument to corroborate, what should you do if you have an incorrect guess and there is no tumor at all after the surgery? Or if the symptoms of two diseases are very similar, the doctor relies on experience to think that you are one of them, only to find out that it is a misdiagnosis after taking the medicine for two months and getting worse. Therefore, a hospital is composed of a doctor’s diagnosis and the supporting evidence of instruments. The doctor is like a big data aggregation center, after aggregating your clinical symptoms and imaging data, the final conclusion is reached through the high speed of the brain and experience. There is already a company developing an intelligent judgment system, which is to arrive at the final result by aggregating all the cases and then letting the computer do the big data analysis by itself and then correcting it by hand. Why do people like old doctors? Because older doctors have seen more patients, have more experience, have a lower rate of misdiagnosis, and have faster diagnosis. From the surgeon’s side, the older surgeon’s surgical design is more rigorous, and the surgical procedure requires fewer actions and less side injuries, and he knows how to handle abnormalities smoothly when he sees them. The film, on the other hand, is an aid to the surgical design. For example, if I do a jaw angle, I can do a precise osteotomy with the assistance of the film, but without the assistance of the film, I need to guess the location of the nerve, and I am afraid of hurting the nerve when I think about it on the operating table. So can instruments replace people at present? Our old president of the Fourth Military Medical University University has made a finished robot for artificial dental implants, which can replace human beings for surgery. However, even if the machine is operated, it needs to follow the program set by the person, and the whole process of unattended can still not be done at present.
