Doctor: It's reasonable to perform surgery on yourself.

It is also thanks to the development of scientific instruments that people can see that polyurethane materials are composed of a double-layer lipid liquid matrix layer, with various glycoproteins and glycolipids in the middle.

Macroscopically smooth.

Microscopically multiphase separation.

This makes this blood vessel have excellent anti-coagulation properties, high elasticity, high strength, and less prone to restenosis.

The problem is that polyurethane was used to make artificial hearts and artificial livers before.

It is difficult and unprecedented to use it in the field of artificial blood vessels.

If it is done well, it will abandon traditional artificial blood vessel materials and overtake on the curve.

If it is not done well, it will be desperate.

…

"Here we are."

Xu Qiu came back to his senses from his contemplation, got off the plane and took a car to the Chinese Academy of Sciences.

"Congratulations, you have completed your first check-in at the Chinese Academy of Sciences!"

"You have received a reward: master-level scientific research ability!"

Sure enough...

Xu Qiu took a deep breath and felt the irrigation of this magnificent knowledge.

His heart suddenly calmed down.

"Guard".

The so-called master-level scientific research ability, compared with comprehension, thinking, logic, talent, and a flash of inspiration, is actually more important than the word "guard".

Guard loneliness.

Guard a heart that never gives up in the face of failure.

Guard a goal, an ideal.

At the same time, Xu Qiu had a new insight into the documents he read in the morning.

Perhaps, neither conventional expanded polytetrafluoroethylene nor the alternative polyurethane is the real answer...

...

"Is this Xu Qiu? He is really a talented person!"

While feeling his ability, a white-haired old man wearing glasses and elegant and gentle strode in at the gate of the Chinese Academy of Sciences.

Xu Qiu immediately came back to his senses and looked over.

He was a little surprised.

The old man who was furious on the phone turned out to be an old scholar.

He also had a beard, which he stroked when he spoke, which was quite a bit like a fairy.

"Professor Dai." Xu Qiu greeted.

Dai Jianye is an authoritative doctor in the field of hand surgery in China. His research direction is the replantation of severed fingers.

Wang Shengde is his favorite student and the student who has the most hope to push the replantation of severed hands in China to a new height.

Unfortunately, when he was 48 years old, a patient who was cured by Wang Shengde chopped him with a knife because he was dissatisfied with the appearance of his hand.

Since then, Wang Shengde has lost the fine control of holding a scalpel forever. Until now, even chopsticks will shake after holding them for a long time.

"So polite." Dai Jianye smiled.

Wang Shengde saw that the other party was in a good mood, and he also greeted him cheerfully: "Teacher, have you eaten..."

"Don't say anything if you have nothing to say." Dai Jianye glanced at him and said unhappily.

Wang Shengde was speechless.

This old man is not in a good mood, he is good to Xu Qiu...

Thanks to Dai Jianye, Xu Qiu and his partner also had a meal in the cafeteria of the Chinese Academy of Sciences.

During the period, they talked about the development of hand surgery.

Fortunately, the development trend of hand surgery in Daxia is very optimistic.

In the last century, hand surgery was dominated by the small country of Xizi.

However, in the past few decades, the domestic economy has developed rapidly, and factories have sprung up one after another.

A large number of workers and countless broken fingers have made the progress of Daxia hand surgery extremely terrifying. In just three or four decades, it has surpassed Western countries one after another, and finally became an unshakable peak in the fields of replantation of broken hands and fingers.

"Last month, several famous doctors from Meiguo came to study and wanted to secretly copy the operation video... There will be no more places for study in this hospital next year, and the International Hand Surgery Summit does not welcome them." Dai Jianye said coldly.

There was unquestionable confidence on his face.

Xu Qiu was deeply touched.

Sure enough, different situations bring up different people.

Cardiac surgery, especially cardiovascular intervention doctors, have a strong dependence on foreign countries.

Without foreign companies to provide artificial blood vessels, they would all be unemployed.

That is why they always smile and worry about gains and losses when facing pharmaceutical companies and foreign counterparts.

The most vivid example is Director Zheng.

When he mentioned that all artificial blood vessels in China were imported, he gritted his teeth.

And when he thought about the possibility of breaking the taboo in the future, he was so excited that he couldn't help himself.

However, hidden under his smile, there was still the helplessness and sadness of being strangled by the neck, like a prisoner dancing in shackles.

Dai Jianye was different.

He was confident and calm in his words and deeds.

Unlike Director Zheng, he was the one who put shackles on people...

And this is the most direct manifestation of the dominance of Daxia Hand Surgery in the international community in every doctor.

...

After lunch, Xu Qiu didn't stay long and planned to return.

"Wait... aren't you here to do business?" Wang Shengde was confused.

Are you here to check in and take pictures? You stood at the gate of the Chinese Academy of Sciences, had a meal and went back?

Dai Jianye was also a little surprised, stroking his beard and said, "Don't worry, Xiao Xu, I asked my students to arrange a place for you to stay. If you like, we can chat tomorrow."

Dai Jianye completely fell in love with this humble and talented young man during the meal.

Xu Qiu said politely, "Professor Dai, I came to feel the atmosphere of the Chinese Academy of Sciences. Seeing so many scholars and academicians, I am more motivated to make progress."

Dai Jianye saw that the other party was really going to leave, so he hurried back to the institute to get a few things.

"This is an X-ray. The patient's finger was broken in a standard way and the repair was almost perfect after the operation. It was the best performance of my life. I have kept it and give it to you."

Xu Qiu and Wang Shengde looked at it at the same time.

It's so beautiful!

"And this is the first edition of the diagnosis and treatment guidelines for the replantation of broken fingers in Daxia... I wrote it myself. Decades ago, when the replantation of broken fingers in China was just starting, I drafted this document, which stipulated the scope of implementation, surgical steps, requirements and postoperative rehabilitation standards of the replantation of broken fingers."

Xu Qiu looked a little more serious.

How much are these two gifts worth? For most people, they are the same price as waste paper.

But, in the eyes of hand surgeons, they are of great significance...

It's a bit like the treasure left by the ancestors.

Wang Shengde swallowed his saliva and said hesitantly: "Teacher, you haven't given me a gift yet..."

Dai Jianye frowned: "When you first followed me, you broke a glass minute hand, remember?"

"Ah?"

"That thing was worth 70 cents back then, I paid for it for you, so it's not a gift?"

"..."

Wang Shengde was a little upset.

Should we treat each other differently?

The old man thought about it and seemed to think that this was not good, so he touched his trouser pocket.

Wang Shengde's heart was alarmed.
