   "Let me ask you again, do you know why this aperture is so large?"

   "Is the aperture in foreign countries large?" The manufacturer said that it has always been required to be the best if foreign countries can do it. As for the medical principles, he could not understand the layman. Scientists tell their manufacturers what is right.

   "Even if you can achieve 30 microns, it is smaller than the 50-something foreign countries."

   "Isn't this up to the standard first? After reaching the standard, your doctors should be able to use it. How can you blame our manufacturer for not being up to the standard?"

   "The problem is that this product does not meet the requirements of the doctor's operation, and there will definitely be a problem."

   "I can't meet any requirements? Isn't this aperture achieved?"

   "I ask you, do you mean the minimum hole diameter by this standard hole diameter?"

   The people from the manufacturer obviously did not expect her point-to-point refutation of Maimang, her expression changed, and her mouth trembled.

   Another classmate sitting on the small bench looked up at Xie, who was speaking at the moment: It's so cool and handsome.

  The teachers present were all silent.

   It is natural for young teachers not to speak. After all, these teachers are not in control of the main scientific research power, and it is basically impossible for them to invent the medical equipment that leads the world. What medical consumables these teachers use in the operation is not up to the leaders to decide. When it was their turn to understand these medical devices, most of them came from the product promotion introductions sent by the representatives of the manufacturers and distributors. For example, in Chang Jiawei's office, many things were given away by the manufacturers for free.

  If you think about it, the other side of giving away means self-evident. People say that good is good. The experimental data of the products delivered and the feedback from peers are true or false. After all, I have to try it myself. If it is really good after the trial, if the foreign manufacturers of these high-end products have a monopoly on the patent rights, they will be treated as trade secrets. Tell you.

Understand? This is why the big bulls are discussing, and there are a bunch of young teachers sitting around, all of whom come here to study and can't interrupt. They determined in advance that a student could not give professional opinions, and it is reasonable and reasonable for the above reasons to not be called deliberately despising students.

   It's just that all the teachers didn't expect this person to be a medical student from the future.

Xie Wanying knew about this artificial blood vessel in the future. This is because she used to be a doctor working in a hospital. She was asked about medical matters, asked future colleagues, checked information, and knew that some future research reports were very interesting. normal.

   This is another question.

  Research on medical devices actually requires the in-depth participation of doctors. The premise of doctors' in-depth participation is that the research funds are rich, or that there are a large number of such cases accumulated in clinical practice for doctors to study.

   These words are currently invisible.

   A very simple example. After the entire artificial blood vessel market has developed for the next two decades, there will be only 40,000 to 50,000 cases per year among the population of 1.4 billion. At the current stage, Axi's mother's aortic aneurysm and aortic dissection surgery, the general hospital's clinical diagnosis ability is low, and there are very few hospital doctors who can perform the operation.
