A problem that has plagued the entire industry for more than thirty years has finally been overcome.

In the past, commonly used artificial blood vessel materials basically had a problem.

During long-term use, artificial materials will undergo aging, degradation and calcification.

This causes artificial blood vessels to easily crack or even be completely destroyed.

Initially, new artificial blood vessels were also troubled by this problem.

However, Xu Qiu waved his hand and started animal experiments directly, implanting the new artificial blood vessels into the carotid arteries of dogs.

One month later, anatomy and pathological examination were conducted. From these experimental blood vessels, the research team found a large number of scattered inflammatory cell infiltrates in the blood vessel walls.

This further targets the root cause of aging calcification - the oxidative degradation of immune response cells.

After that, the institute focused its research and development efforts on improving the tissue compatibility of the material, so that the material could induce less or even no inflammatory response, completely solving this problem.

In the past three months, Linhai Research Institute, Linhai University, and Linhai First Hospital cooperated and finally completed animal experiments on several experimental dogs!

A total of six cases of dog artery implantation were performed. Yang Chenxi, Xu Qiu, and the directors of cervical surgery and cardiac surgery jointly performed the operations.

In the end, all survived.

Moreover, these six dogs are still healthy and active after the operation, and the six-millimeter artificial blood vessel fits their carotid arteries almost perfectly.

Among them, the experimental dogs named "Linlin" and "Haihai" used a 4-mm blood vessel!

Of course, four millimeters can only be used in laboratories and animal experiments.

It has more technical problems and bigger flaws!

If you want to promote it to clinical practice, you have to wait at least two or three years.

The current focus of the institute is still six millimeter blood vessels.

The news of the survival of the first batch of experimental animals was also signed by Xu Qiu, Yang Chenxi, Ren Chao, Wang Shengde, Fu Qing, the first secretary of Baiyun Province, and others, and submitted a report to the country.

according to rules.

After experiments on a certain number of animals are successful, the technology can enter the human clinical trial stage.

After passing the three clinical trial evaluations, you can officially establish the listing and go to the market!

Right now, the six living dogs are the strongest evidence of the feasibility of this new type of artificial blood vessel.

…

At this moment, the industry was shocked!

"Linhai Research Institute?"

"Animal experiments on blood vessels in restricted areas were conducted here, and they were successful. How reliable is it?"

"The initiator is Xu Qiu...that Xu Qiu from Linhai No. 1 Hospital?"

"When did he come here to get artificial blood vessels? Isn't Xu Qiu a big boss in brain surgery?"

People can't understand it, and they can't understand it.

at this time.

Fuwai Hospital.

Fuwai, which once won the title of "Pioneer of Artificial Blood Vessels" and "Advance Team", has been at the forefront of autonomous blood vessel research and development in Daxia under the leadership of Yang Chenxi.

But now, Yang Chenxi has left, and a large number of scientific researchers have been transferred away by Professor Yang and Professor Ma Qin.

Within a few months, the vascular center in Fuwai was nothing more than an empty shell.

Even the uncles and aunties in the cafeteria who are familiar with the tastes of these scientific researchers are on business trips at public expense.

If the dean of Fuwai hadn't stopped her, the sweeping lady would have been taken away as well.

As for the previous 6.5mm lightweight imported artificial blood vessel, it has long been shelved.

People, money, and equipment are all gone!

In order to express his apology, Yang Chenxi immediately called his old club and announced the news.

Dean Fuwai felt his whole body shaken.

it turns out……

Really successful?

The 6mm blood vessel, which has been designated as a restricted area by giants such as McVie and Terumo, actually took the lead in completing the first round of animal experiments in an inconspicuous prefecture-level city in Daxia, and is about to enter the human clinical stage?!

Dean Fuwai suddenly burst into tears.

Although Fuwai is a nationally renowned comprehensive tertiary hospital, its trump card has always been vascular surgery and cardiac interventional surgery.

Previous deans basically came up from outside the heart and blood vessels. They all held their breath and wanted to make achievements in this field!

Now, they finally saw a glimmer of hope.

Although not outside Fuwai.

However, Yang Chenxi and others from Fuwai were involved.

This is a domestic artificial blood vessel made in Daxia without any foreigners. It is a small-diameter artificial blood vessel that breaks the 6mm restricted area!

"More than 600,000 patients are waiting for vascular reconstruction. If successful, this will be the greatest feat of Daxia doctors!"

…

At the same time, Academician Chen, Lin Xie, Shen Hua and others also received news of the great success of Linhai Research Institute's six-mm artificial blood vessel animal experiment.

"Success?"

Lin Xie was shocked, "It has reached the clinical trial stage so quickly..."

This kid.

I promised myself that I would make some achievements in hepatobiliary surgery.

Why did you go to vascular surgery first?

After finishing the project at hand, if Xu Qiu's side goes well, he may have completed the clinical trial and officially announced that Daxia has broken through the restricted area.

When the time comes, he will go to Linhai in person and ask Xu Qiu when he will break the restricted area for hepatobiliary surgery.

Radical treatment of hilar cholangiocarcinoma and resection of the caudate lobe are considered forbidden areas and no-man's land in hepatobiliary surgery.

Doctors have never been able to extend the scalpel to these extremely difficult areas.

Academician Chen is also doing research, but he is already eighty-eight years old and is gradually becoming unable to do what he does.

The students he trains are all mediocre people like Gao Pei'an who will always live under his aura as "Academician Chen's student".

Although they were cultivated by Academician Chen and rose to prominence, this also became their biggest shackles.

Not being able to surpass Academician Chen will of course be a shackle.

However, now Academician Chen sees hope in Xu Qiu.

This guy's research is complicated, but he is incredibly proficient in every field. It will not be easy for him to do more hepatobiliary surgery!

now.

Lin Xie also had the same idea.

This guy has a lot of research skills. Wouldn't it be easy for him to do more hepatobiliary surgery and bone reconstruction?

Academician Shen Hua: Let’s do more restricted areas of brain surgery.

Wang Shengde: More hand surgery.

Kong Huixia: Come to the obstetrics and gynecology department more often.

Wang Ping: One more pulmonary embolism...

…

On the same day, an hour after Linhai Research Institute submitted it for review, the confidential report was sent to the highest level.

According to the normal process, it may take several weeks or even months to get to this point.

However, there were so many people calling and writing to recommend it, including two or three academicians alone!

The opening of this green channel shocked even the top leaders.

"Small caliber...animal experiments...all survived?"
Chapter completed!
