Looking at Milton with a disappointed face, Fang Hong suddenly smiled and said, "Although I didn't have the opportunity to teach at your school, I happen to have a research direction in my hand now, and I want to cooperate with your school." ”

"Oh? What research direction? Milton asked curiously.

"Speaking of which, this research direction is still inspired by cardiac catheterization, in fact, compared to the heart, there is another organ that requires us to go deeper into its interior for observation and diagnosis, and that is the stomach, you say, Professor Hanwell." Fang Hong gradually asked the dean of the medical school in the middle of the banquet.

Hanwell nodded and replied: "That's right, compared to other organs of the human body, the stomach is the part with the most symptoms, and it is also the most complicated and tricky part to diagnose and treat, because once the direction of diagnosis is wrong, then the follow-up treatment will be useless and even have side effects, but at present, there is no effective means to achieve the means of going deep into the stomach to observe and diagnose the diagnosis that Dr. Fang said." ”

Fang Hong gradually shook his finger and said: "It's not that it's nothing, it's just that this method is not mature at present, that is, the semi-flexion gastroscope developed by German scholars Schindler and Wolfer six years ago!" ”

"Oh, the kind of tube you mentioned, that thing is indeed useful, but the range that can be observed is too small, and the operation is not flexible, so it does not play much role at all." Hanwell said disapprovingly.

Fang Hong gradually defended: "Although it has little effect, I think Dr. Schindler's improvement direction is correct, but the materials they use are not suitable, so they can't play the role of gastroscopy." ”

"Oh? Dr. Fang, what do you think is the most suitable material? Hanwell asked curiously.

Fang Hong gradually raised two fingers and replied, "Fiber!" ”

Even in 2017, when medical technology is highly developed, gastroscopy is still the most reliable way to examine the esophagus, stomach, and duodenum.

In fact, the earliest gastroscopy was inspired by the German doctor Kusmore in 1868 when he watched the acrobatic performance "Sword Swallowing", when he saw the performer slowly insert a long sword from his mouth, he wondered if it was possible to insert a tube into the esophagus up to the stomach to check the lesions.

Based on this assumption, the first esophagogastroscope was born, which was composed of a metal straight tube and a lens mounted at the end, but unfortunately because there was no electricity in that era, it could only be illuminated with candles, so although the tube was inserted, it was not clear to see the situation inside, and the metal tube was extremely easy to damage the esophagus, so this invention was abandoned after not being used for long.

It wasn't until 1932 that the two German scholars who Fang Hongjian said just now invented the semi-flexion gastroscope with a tube and contrast agent, but unfortunately its practicability is not strong, as Hanwell said, the observation range is too small, and Fang Hongjian wants to steal the invention of the American scientist Haskovitz in 1957 - fiber gastroscope, in fact, before that, that is, in 1950, the doctor of the University of Tokyo in Japan, Uji Dakang, invented the gastroscope camera, but Fang Hongjian felt that this camera still has limitations, It is better to get the fiber gastroscope out in one step, and he will never be able to complete this kind of work, so he thought of taking advantage of this academic exchange opportunity to cooperate with Johns Hopkins University.

Looking at the confused expressions of everyone at the banquet, Fang Hongjian continued to explain: "According to the principle that glass fiber can guide light and the beam can be imaging, I think it is possible to carry out the test and exploration of fiber gastroscope, which is characterized by soft mirror body, full bendability, and easy operation; Good light guiding performance and clear imaging; Wide field of vision, no blind spots; It is also possible to examine the esophagus and duodenum homeopathically, and most importantly, the pain and danger to the patient are greatly reduced. ”

"So, Dr. Fang, you've already started conducting experimental research?" Milton asked tentatively.

Fang Hong shook his head awkwardly and replied: "Hey, because it is limited to experimental conditions, what I said is theoretical data, so I hope to reach a cooperation with your university and strive to make a more accurate data support for the feasibility of this fiber gastroscope during this academic exchange." ”

This time, before Principal Milton could speak, Dean Hanwell directly agreed: "Doctor Fang, as a doctor, I am very optimistic about the practical prospects of the fiber gastroscope you just mentioned, if such a medical device can really be manufactured, it will relieve the pain of countless patients with stomach problems, as a doctor, I will do my best to work with you to conduct fiber gastroscopy research." ”

Although Hanwell preemptively agreed to make Milton feel a little faceless, he knew that this Hanwell was a medical maniac, and he couldn't control his emotions as long as he encountered new drugs and new medical equipment, and he also knew that once this fiber gastroscope was really successfully developed at Hopkins University, it would greatly enhance the medical status of the school, so he also supported: "Well, we at Hopkins University will provide full support for this research work!" ”

So in the next few months, in addition to making a few lectures on vitamin K extraction and the practical application of cardiac catheterization, most of the time was devoted to the development of fiber gastroscope, at this time he couldn't help but sigh again, it is really the foundation that determines the development, even if he has the idea of this in China and is very sure that it will definitely succeed, but there is no condition for testing and production at all, because this involves the multidisciplinary collaboration of biology, medicine and engineering, Not to mention in China, even in the world, there are not many universities that can do it at present.

After registering the patent and signing a long-term cooperation agreement and accepting the invitation of an honorary lecturer at Johns Hopkins University, Fang Hongjian finally returned to Shanghai with Wang Jiazhi, who had long been homesick.

PS: Actually, I originally wrote several chapters of this plot, but then I thought it seemed to be a little off the main line, and the editor didn't let me write too many boring medical plots, so it was reduced to this chapter, anyway, the main purpose of this plot abroad is to quickly advance the timeline, otherwise if I come to a sentence "two years later", you will definitely have to spray me.
