There was a time when domestic manufacturers were racking their brains to think about how to achieve the foreign goal of large apertures.
"Let me ask you again, do you know why this aperture needs to be larger?"
"The apertures in foreign countries are larger," said the manufacturer. They have always demanded that foreign countries be the best. As for the medical principles, laymen can't understand them. The scientific researchers said to their manufacturers.
Whatever you do is right.
"Even if you make it 30 microns, it's still smaller than the 50 microns abroad."
"Why don't we meet the standard first? Once we reach the standard, your doctors should be able to use it. Why blame our manufacturer for not being up to the mark?"
"The problem is that your product cannot meet the requirements of doctors during surgery, and there will definitely be problems."
"What requirements did I fail to meet? Didn't the aperture meet the requirements?"
"Let me ask you, does your standard aperture refer to the minimum aperture?"
The people at the manufacturer obviously did not expect her point-to-point refutation, their expressions changed and their mouths trembled.
Another classmate sitting on the small bench looked up at the student Xie who was speaking at this moment: He is so cool and handsome, this is a sentence that seals his throat with a sword.
All the teachers present were silent.
It is natural for young teachers not to speak. After all, these teachers do not hold the main power in scientific research. It is basically not their turn to invent and lead the world's medical equipment. It is not up to the leaders to decide what medical consumables these teachers use in operations.
Their own understanding of these medical devices mostly comes from product promotion introductions sent by representatives of manufacturers and distributors. For example, there are many things in Chang Jiawei's office that are free gifts from manufacturers.
If you think about it, it is self-evident what the other side of the free gift means. People praise it to the extreme and say it is good. The experimental data of the delivered product and the feedback from peers are true or false. You have to try it yourself after all.
If it is really good, if these foreign manufacturers of high-end products have a monopoly on patent rights, they will treat them as trade secrets. The performance is: I will praise you that my product is good, but how good this product is, I will never tell you even to death.
.
Do you understand? This is why the experts are discussing, and there are a bunch of young teachers sitting around, all of whom are here to study, but they can’t interrupt. They decided in advance that a student cannot express professional opinions. According to the above reasons, it is reasonable and true.
It cannot be called deliberately despising students.
But all the teachers didn't expect that this person was a medical student who came back from the future.
Xie Wanying knew about this artificial blood vessel in the future. This was because she had also been a doctor working in a hospital. She had been asked about medical matters, asked future colleagues, checked information, and knew that some future research reports were very
normal.
This is another question.
The research on medical devices actually requires the in-depth participation of doctors. The prerequisite for the in-depth participation of doctors is that there are sufficient research funds, or there are a large number of clinical cases and accumulated data for doctors to study.
These words cannot be seen currently.
A very simple example: after the entire artificial blood vessel market develops in the next 20 years or so, there will only be a demand for 40,000 to 50,000 cases per year among a population of 1.4 billion. At the current stage, aortic aneurysm and aortic dissection surgeries like Ahi’s mother can only be performed in ordinary hospitals.
Clinical diagnostic capabilities are low, and there are very few hospital doctors who can perform surgeries.
