"The main reason is that the road is a bit congested." Unlike Yu Heng, Su Min's social skills are much stronger.

"Brother Cheng, Yu Heng." The titles are different.

Zhou Chengcheng said: "It's just in time, and we've just arrived, so let's order some food. It's been almost a month since we came back, and this is the first time we've met."

"You are more familiar with the devil, so you two choose dishes. I do as the Romans do."

Only then did Zhou Cheng take out the menu. It was the first official meeting in Shanghai, so he couldn't show too much.

Su Min was familiar with himself, and drew two dishes in a swish, and then said: "Brother Cheng has caused a lot of trouble in Shanghai recently, and he is almost becoming an Internet celebrity. Today, the whole Internet is looking for you. I hope you can register." Douyin, become a vlogger with popular science videos."

Su Min, who has returned to Shanghai, has such a strong smell?

Zhou Chengcheng said: "Then the hero or heroine is you."

Seeing that Zhou Cheng caught her trick so quickly, Su Min smiled and squeezed her fist: "I don't play prostitution. Eagle fighting is suitable for me. Fist chicken."

Su Min handed the menu to Yu Heng who was silent, and specifically made Mandarin very standard.

"There is no big G in Pinyin, right? I remember it seems to be cut." Zhou Cheng remained calm.

Su Min immediately clasped his fists at Zhou Cheng: "Brother Cheng's kung fu is admirable for the original taste of the Department of Orthopedics."

"Su Min, your skin is so white, and you speak so nicely. Has anyone said that your mouth actually looks like a sliced ​​old steamed bun? The taste is very similar!" Zhou Cheng asked with a smile.

Damn, I came to look for you on purpose, but you suppressed me as soon as I came up, so that's okay.

Su Min immediately closed her mouth, understanding Zhou Cheng's meaning.

"It's more like pursing your lips. Yu Heng, don't you think so?"

Yu Heng raised his head, looked at Zhou Cheng and Su Min, and shook his head like an innocent bystander: "I don't know what you are talking about. Brother Cheng, I have ordered, you can order."

"It's good to add a bean."

Zhou Cheng raised his head and gave Yu Heng a strange look. This guy is not the honest person in his face.

Su Min straightened her body slightly, without blushing, and pretended not to understand: "Brother Cheng, my teacher told me how close I can be to you, can you be gentle?"

Zhou Cheng curled his lips: "Didn't you all look like this when you were in the capital?"

After ordering the menu, pass it to the waiter.

Yu Heng said: "Brother Cheng, you looked quite innocent when you were in the capital."

Well, I know that Yu Heng is actually an old driver who hides quite deeply.However, Yu Heng didn't talk much, so Zhou Chengcheng asked, "Yu Heng, what are your thoughts on the topic that you communicated with Yang Yifeng last time?"

"I originally planned to call Yang Yifeng here, but he has gone back to Shashi."

Getting back to the topic, Su Min immediately poked out his ears and listened carefully.

"Still grinding slowly." Yu Heng said and glanced at Su Min.

The corner of Su Min's mouth trembled.

Zhou Cheng waved his hand: "Let's talk about business, don't think about the steamed buns, if you want, you can order another one."

Su Min was numb and didn't dare to shut up, what's wrong with his fucking white skin?

Only then did Yu Heng become serious: "I found out that there is a problem, and it's quite a big one."

"Our original design was to set up this topic first, but in the process of searching the literature, we found that there are not many reference literature, and there are jumping stages."

"If you want to go directly to the repair of scars and skin folds, there will be loopholes. But if you want to perfect all the theoretical planning first, it will be too winding, and the progress of the theory will have twists and turns," Yu Heng said. , glanced at Su Min.

Then seeing Su Min's beating expression, he raised his hand honestly and said, "I'm not talking about anything, we're discussing academic issues in a serious way."

"And you were the one who got the word out."

"Extremely small success..."

When Yu Heng said this, he suddenly looked at Zhou Cheng again: "I can't go on, Brother Zhou Cheng, tell me."

Zhou Cheng took a deep breath and held back Yu Heng's connotation to himself.

Chapter 271 Teacher, I understand

After the three orthopedic surgeons showed their talents, the topic returned to the right track.

Yu Heng said: "I'm not kidding anymore, Brother Zhou Cheng, do you have any other ideas about the topic we discussed last time?"

"My teacher intentionally asked me to come to you to inquire about it, but I know you must be very busy these days. I don't want to disturb you. I planned to ask you after you have finished your work."

"I'm stuck in a dead end now. If I want to make a detour, I don't know when I will do it." Yu Heng didn't forget his reason for coming.

Zhou Cheng took the initiative to invite, which meant that Zhou Cheng was free.

Another level of adult thinking is to consider other people's feelings. Now that Zhou Cheng has his own project in progress, the time is not completely at his disposal. If he is distracted by himself, it is naturally not good.

Zhou Cheng glanced at Su Min first, although he is a shameless person, he should not be underestimated, if he has a better opinion, he might be able to comprehend it better.

Su Min said: "I just got a general idea of ​​what you are talking about. Brother Cheng, you should give your opinion, and I won't get involved."

"You are attacking the needle." Zhou Cheng added.

The corners of Su Min's mouth twitched, as expected he had distorted the atmosphere after coming here.Seriously speaking, it can also be misunderstood.

Zhou Cheng tilted his head and said to Yu Heng: "Yu Heng, sometimes, we should not only focus on theory, but limit all our vision to operations."

"The root cause of human progress is the use of tools. We are good at using tools, and then using tools to transform nature to a certain extent and conform to nature is the most appropriate way."

"If it is not feasible to rely solely on tendon transposition, tendon repair and other theories to balance deformities and scars, why don't we borrow another set of tools from plastic surgery?"

Yu Heng raised his head, looked left and right, and felt that he was being suppressed.

Frowning tightly: "Plastic surgery? What tools do you borrow?"

Zhou Cheng currently has a high reserve of skills and a solid reserve of knowledge and theory systems. He has many perfect-level skills, so he naturally knows that from proficiency to perfection lies in the perfection of the theoretical system. Most of the redefinitions are multidisciplinary, even interdisciplinary.

Why can small incision open reduction and internal fixation be implemented?

It is because of the assistance of the equipment. Without this equipment, it is basically difficult for you to perform such an operation. Only specific fractures are suitable.

After pure theory can't go any further, you have to borrow tools. This is where Zhou Cheng hid Yu Heng and Hu Xianhe.

An objective substitute for patents, precisely because of this.

"Sutures. But they are not ordinary sutures, nor are they cosmetic sutures, but special sutures for muscles. Think about it, where is the most difficult part of tendon reconstruction and muscle reconstruction and repair?"

"Sewing."

Zhou Cheng went on to talk eloquently: "The reconstruction of bone defects lies in the assistance of internal fixation. The repair of fractures lies in bone grafting. The reconstruction of tendons lies in suture fixation."

"Sports medicine has a nail row system, which can also be used for reference."

"But the more important part is the suture, and the suture method is also more important, but if the suture can achieve tension without cutting, we must start from this direction."

Yu Heng understood, and his understanding of the subject was not superficial: "But isn't this the task of materials science? Where is such a suitable suture now? Tendon suture?"

"But tendon sutures are not suitable for muscle sutures. Tendon sutures are too tense. Tendons are very tough and can withstand cutting forces. If ordinary sutures are used to suture muscles, there will be a lot of scar tissue."

"After the skin scar is removed, it is not easy to use cosmetic sutures."

"Yes." Zhou Cheng said casually.

"This thing, I can give you some pointers at that time. You can try to do animal experiments first to see if this suture is feasible."

"Are you willing?" Zhou Cheng was waiting for him here.

In fact, Zhang Zhengquan can find someone to do this kind of thing, but it's not good. Yu Heng's participation is equivalent to something from Huashan Hospital, and Huashan Hospital will definitely come forward to help.

At that time, under the combined factors of advertising effect, college effect, Hu Xian and professor's team effect, hospital effect, etc., it will be difficult for his sutures to become popular.

And it is based on Huashan Hospital going out. It is not so easy for ordinary people to crack down on counterfeiting.

The cooperation of adults lies in reciprocity.

"Can you really find this kind of thing?" Yu Heng's eyes continued to scan Zhou Cheng up and down.

"Didn't you know this thing a long time ago, and then wait here for me?"

Yu Heng is not stupid, but very smart.

During the discussion before, Zhou Cheng put forward the idea.

Now that he encountered a problem, Zhou Cheng proposed a solution and tools. Isn't this a pit waiting for him to jump into?

Yu Heng is not Yang Yifeng either, Yu Heng will ask questions that Yang Yifeng knew but didn't ask.

And this made Yu Heng very frustrated. If the things he pursued and researched hard were all under the design and arrangement of others, and he was just a tool man, then what's the point?

Zhou Cheng couldn't deny it: "This is not waiting, is it?"

"Yu Heng, you told me about this before, so I did the calculations. You gave me an idea of ​​inspiration, so I found my friend and designed such a thing."

"Now you say that I'm waiting for you, you think too highly of me."

People have five needs, and self-realization is one of the more important links and parts. If Yu Heng has no sense of participation and value, in such a person's heart, he will not be interested.

On the contrary, it is a manifestation of disrespect.

Yu Heng looked at Zhou Cheng thoughtfully, "Is what you said true?"

"I have a good project, I will do it for you for nothing, I am not Su Min, I was reminded by Lang."

"And this kind of suture, I have already had the idea of ​​designing it, it was last year, but at that time my friend and I prepared it based on another subject, and now the preliminary prototype has come out."

Zhou Cheng flickered slowly.

Sometimes it’s not a bad thing to take a step back properly. Don’t take up all the good things. It’s good to have a big head and make friends.

"However, as for where this suture will be used, you will know when the time comes, and I won't reveal it in advance. Of course, if you don't want to try it, it's okay."

Yu Heng thought about Zhou Cheng's words carefully, and there were no loopholes.

The design of sutures is not something that happens overnight, unless Zhou Cheng has planned it long ago, and his own research direction has not yet come out at that time, how is this possible?

It is impolite to ask Zhou Cheng about the direction of the project. The reason why he asked Zhou Cheng to talk about his project was because Zhou Cheng was the one who suggested it, and so was Yang Yifeng. benefit.

Su Min rolled her eyes: "Don't get involved with me, I'm very serious."

Yu Heng and Zhou Cheng ignored Su Min. After thinking about it for a while, Yu Heng sighed and said, "There is such a good thing, I want to see it."

"Brother Cheng, is it convenient for you to tell me, where did you plan to use this suture?"

Zhou Cheng smiled faintly, pointed to his arm, and said, "Interosseous membrane."

"The interosseous membrane is more easily damaged than muscle, and it is a purer fibrous structure. The repair of the interosseous membrane actually has a great impact on the function of the forearm. I can only say this."

Yu Heng didn't ask too much.

There is an interosseous membrane between the ulna, radius, and tibia and fibula, but in the process of fracture surgery, most of them are not able to complete this. The current theoretical system is that once the interosseous membrane is damaged, it will be damaged.

If you probe more carefully, it is not to test Zhou Cheng's true heart, but to steal secrets.

The interosseous membrane and muscle are both fibrous structures. On the contrary, compared with the interosseous membrane, the muscle fiber has a certain degree of toughness. It is reasonable to use it by analogy.

Yu Heng then smiled: "Then thank you Brother Cheng."

Then he straightened his expression: "But Brother Cheng, please rest assured, I will never leak any secrets before your subject is released."

After finishing speaking, Yu Heng will start to work hard on the next test plan. If there is a tool that can help him overcome the difficulties of the current project, then the next step is to go through the various procedures of the test. .

……

Hearing this, Su Min said enviously, "It's so good to lie down and win."

The interosseous membrane tool is applied to the muscle tissue, which is a shortcut. It can only be said that Yu Heng's luck is really good.

Yu Heng just lowered his head and ate, not listening to Su Min's half-envious, half-envious words.

Zhou Cheng immediately rolled his eyes at Su Min, and asked, "Haven't you considered that there are actually loopholes that can be exploited in the project idea designed by Yu Heng?"

Su Min and Yu Heng raised their heads at the same time and looked at Zhou Cheng.

"Where do the substitutes come from for muscle and tendon repair and reconstruction?" Zhou Cheng asked.

"Take autologous tendon instead?" Yu Heng, who is familiar with joint surgery and hand surgery, said without hesitation.

"Bone grafting can be divided into autologous bone and allogeneic bone. Isn't it possible for tendons and muscles?"

"The tendon structure itself is inactive. Muscles can also replace crawling. Muscles have size, and they can completely heal and crawl with fractures. Isn't it very similar?"

Some muscles are non-renewable, but some cells are not!

Su Min, you idiot!
