For a while, domestic manufacturers were racking their brains to figure out how to achieve the goal of large apertures as achieved abroad.
"Let me ask you again, do you know why this aperture has to be so large?"
"The apertures in foreign countries are bigger." The manufacturer said that they have always required benchmarking against foreign countries and that the best they can achieve is the best. As for the medical principles, he is an outsider and cannot understand them. The scientific researchers told their manufacturers to do what they want.
"Even if you can make it 30 microns, it's still smaller than the 50 or so microns that are often achieved abroad."
"Shouldn't this meet the standards first? If it does, you doctors should be able to use it. Why are you blaming us, the manufacturer, for not meeting the standards?"
"The problem is that your product cannot meet the requirements of doctors during surgery. There will definitely be problems."
"What requirement am I failing to meet? Isn't this aperture already met?"
"Let me ask you, is the aperture that meets the standard the minimum aperture?"
The manufacturer's staff obviously did not expect her sharp and pointed rebuttal. Their expressions changed drastically and their lips trembled.

The other students sitting on the small bench looked up at Xie who was speaking: He is so cool and handsome, this sentence is the final word.
All the teachers present were silent.
It is natural for young teachers to keep silent. After all, these teachers do not hold the main scientific research power, and it is basically not their turn to invent world-leading medical equipment. What medical consumables these teachers use in surgery is decided by their leaders, and they have no say in it. When it comes to their understanding of these medical devices, most of them are introduced to the products through the sales promotion of the manufacturer's distributor representatives. For example, Chang Jiawei's office is full of things given away by the manufacturer for free.
Think about it, the other side of free gift means something self-evident. If someone praises it to the sky, it must be good. You have to try it yourself to see the product test data and feedback from peers. If it is really good after trying it, such as these high-end products, foreign manufacturers have a monopoly on patents, and they will treat it as a trade secret, which means: I praise my product to you, but I will never tell you how good it is.
Do you understand? This is why the experts are discussing, and a bunch of young teachers are sitting around them. They are all here to learn and cannot interrupt. They have determined in advance that a student cannot give professional opinions. According to the above reasons, it is reasonable and reasonable, and it cannot be said that they deliberately despise the students.
But all the teachers didn't expect that this person was a medical student who came back from the future.
Xie Wanying had learned about artificial blood vessels in the future because she had been a doctor working in a hospital. She had been asked about medical matters, asked her future colleagues, and checked information. It was normal for her to know some future research reports.
This brings us to another issue.
The research on medical devices actually requires the in-depth participation of doctors. The premise for the in-depth participation of doctors is that there is sufficient research funding or there is a large amount of clinical case data accumulated for doctors to study.
These words cannot be seen at present.
A very simple example is that after the entire artificial blood vessel market develops in the next 20 years, there will be only 40,000 to 50,000 cases per year among the 1.4 billion population. At the current stage, the clinical diagnosis ability of general hospitals is low for aortic aneurysm and aortic dissection surgery like Yaxi's mother, and there are very few doctors in hospitals who can perform the surgery.
