Chapter 307: Breaking the artificial blood vessel forbidden zone! The whole country is shocked!
A problem that has plagued the entire industry for more than 30 years has finally been solved.
In the past, commonly used artificial blood vessel materials basically had a problem.
During long-term use, artificial materials will age, degrade and calcify.
This causes artificial blood vessels to easily crack or even completely destroy.
At the beginning, new artificial blood vessels were also troubled by this problem.
However, Xu Qiu waved his hand and started animal experiments directly, implanting new artificial blood vessels into the dog's carotid artery.
A month later, after dissection and pathological examination, the research team found a large number of scattered inflammatory cells infiltrating in the vascular wall from these experimental blood vessels.
This further locked the root cause of aging calcification - oxidative degradation of immune response cells.
After that, the institute focused its research and development efforts on improving the tissue compatibility of the material, making the material less induced, or even not induced, inflammatory reactions, and completely solving this problem.
In these three months, Linhai Research Institute cooperated with Linhai University and Linhai First Hospital, and finally completed animal experiments on several experimental dogs!
A total of six dog artery implants were performed, and Yang Chenxi, Xu Qiu, and the directors of carotid surgery and cardiac surgery jointly performed the operation.
In the end, all of them survived.
And the six dogs are still healthy and lively 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 four-millimeter blood vessel!
Of course, four millimeters can only stay in the laboratory and animal experiments.
It has more technical difficulties and greater defects!
If you want to promote it to the clinic, you have to wait at least two or three years.
At present, the focus of the institute is still six-millimeter blood vessels.
The news of the survival of the first batch of experimental animals was also jointly signed by Xu Qiu, Yang Chenxi, Ren Chao, Wang Shengde, and Fu Qing, the first secretary of Baiyun Province, and submitted a report to the state.
According to regulations.
After the experiment is carried out on a certain number of animals and is successful, this technology can enter the human clinical trial stage.
After three clinical trial evaluations are qualified, it can be officially established and put on the market!
At present, the six living dogs are the most powerful evidence of the feasibility of this new artificial blood vessel.
…
At this moment, the industry is shocked!
"Linhai Research Institute?"
"This place has done animal experiments on restricted blood vessels, and it was successful. How credible is it?"
"The initiator is Xu Qiu...Xu Qiu from Linhai First Hospital?"
"When did he come here to make artificial blood vessels? Isn't Xu Qiu a big shot in neurosurgery?"
People can't understand, and can't figure it out.
At this time.
Fuwai Hospital.
Fuwai, which once won the title of "artificial blood vessel vanguard" and "advance team", has always been at the forefront of Daxia's independent blood vessel research and development under the leadership of Yang Chenxi.
Now that Yang Chenxi has left, a large number of scientific researchers have been transferred away by Professor Yang and Professor Ma Qin.
In a few months, Fuwai's vascular center is left with only an empty shell.
Even the uncles and aunts in the cafeteria who are familiar with the tastes of these scientific researchers have gone on business trips at public expense.
If the dean of Fuwai hadn't stopped him, the cleaning lady would have been taken away.
As for the previous 6.5mm light imported artificial blood vessels, they have been shelved long ago.
People, money, and equipment are all gone!
To express his apology, Yang Chenxi immediately called his old employer and announced the news.
The dean of Fuwai felt a shock all over his body.
It turned out that...
It really succeeded?
The 6mm blood vessels that were designated as restricted areas by giants such as McCoy and Terumo actually took the lead in completing the first round of animal experiments in an inconspicuous prefecture-level city in Daxia, and are about to enter the human clinical stage? !
The dean of 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.
The previous deans were basically promoted from cardiac surgery and vascular surgery, and they all held their breath and wanted to make achievements in this field!
Now, they finally see a glimmer of hope.
Although not in Fuwai.
But, Yang Chenxi and others from Fuwai participated.
This is a domestic artificial blood vessel made in Daxia without a single foreigner, a small-caliber artificial blood vessel that breaks the 6mm restricted area!
"More than 600,000 patients are waiting for vascular reconstruction. If it succeeds, it will be the greatest feat of doctors in Daxia!"
...
At the same time, Academician Chen, Lin Xie, Academician Shen Hua and others also received the news that the animal experiment of six-millimeter artificial blood vessels in Linhai Research Institute was a great success.
"Success?"
Lin Xie was shocked, "It has reached the stage of clinical trials so quickly..."
This kid.
He promised to make some achievements in hepatobiliary surgery.
Why did he go to vascular surgery first!
After finishing the project at hand, if Xu Qiu goes well, perhaps the clinical trial has been completed and Daxia has officially announced that it has broken through the forbidden zone.
At that time, he will go to Linhai in person and ask Xu Qiu when he will break some forbidden zones for hepatobiliary surgery.
Like radical treatment of hilar cholangiocarcinoma and resection of the caudate lobe, they are all regarded as forbidden zones and no-man's land in hepatobiliary surgery.
Doctors have never been able to extend their scalpels to these extremely difficult areas.
Academician Chen is also doing research, but he is already 88 years old and is gradually unable to do it.
The students he trained were all mediocre people like Gao Pei'an who always lived under the halo of "Academician Chen's student".
Although they were cultivated by Academician Chen and rose to prominence, this also became their biggest shackle.
Of course, it would be a shackle if they could not surpass Academician Chen.
However, Academician Chen now saw hope in Xu Qiu.
This kid's research was miscellaneous, but he was incredibly proficient in each field. It would be easy for him to do more hepatobiliary surgery!
At this moment.
Lin Xie had the same idea.
This kid's research was miscellaneous. It would be easy for him to do more hepatobiliary surgery and bone reconstruction.
Academician Shen Hua: One more restricted area operation for brain surgery.
Wang Shengde: One more hand surgery.
Kong Huixia: One more obstetrics and gynecology.
Wang Ping: One more pulmonary embolism...
...
On the same day, one hour after Linhai Research Institute submitted it for review, the confidential report was delivered to the top management.
According to the normal process, it may take several weeks or even months to reach this step.
However, there were too many people who called and wrote to recommend it, including two or three academicians!
This green channel even shocked the top leaders.
"Small caliber...animal experiment...all survived?"
When he finished reading the document in his hand, he was stunned.
