Chapter 2653 [2653] I can't wait

The market size is small, there is no data accumulation, manufacturers, clinicians, what to use to research products. Compared with foreign countries, there is no need to know what to compare. Only know blow holes.

Xie was aiming at the essence of the blow from the very beginning. Don’t be easily led by the nose. She came back with relevant data from the future, and the research report made after the number of domestic cases increased to a certain number gave some substantive points to why domestic products are worse than foreign ones.

"The maximum pore size abroad can be 80 microns, and the average is 50 microns. This is a small artificial blood vessel. You can also say that if you want to achieve 80, you can do it, but if you want to achieve 80, you need to do The ones that don’t have their small artificial blood vessels are made of large artificial blood vessels, relying on large ones. After all, the production process is different. Domestic products are several times more stretched than foreign ones.”

The bulk is drawn and sintered.

The man from the manufacturer kept his eyes fixed on her face: Are you a doctor? Are you sure it's just a doctor?

is really just a doctor. Xie Wanying told the other party about the key points of artificial blood vessels in the eyes of doctors: "The most challenging thing about artificial blood vessels is not large-caliber tubes, but small-caliber tubes that are small to a certain extent."

The difficulty of large-diameter pipes and small-diameter pipes is the strength, fearing that the strength is not enough. Large-diameter pipes may be able to build up strength by adding thickness. Small to very small bore tubes do not have this shortcut to pull strength. Looking at the world is full of difficult projects, and it is even more difficult for the artificial blood vessel business that has just started in China.

When the teachers discussed it today, she immediately realized that she was talking about small-caliber tubes. Why, one, Mr. Fu didn't mention the recent surgery case of Axi's mother at all. The latest application cases that meet the requirements can be presented at the meeting by the way. Second, the problems with the anastomosis fit the problems revealed by the scientific research reports she has seen in the future.

"When our surgeons perform surgical sutures, the needle and thread are located in an area about 2mm away from the orifice of the suture. What determines the fixation strength of the suture thread is the crystallinity of the material, the width of the nodes in the material, and the length of the fiber, not a single aperture. The crystallinity degree of domestic products is compared with foreign ones. Have you done any data? The longer the fiber length, the smaller the node width, and the smaller the strength. The nodes made by foreign products are uniform, and some have large apertures but short fibers. It is admitted that the larger the aperture, the longer the fiber is. When it comes to the operation, if the doctor just cuts the worst node with a pair of scissors, the problem of relatively uniform foreign nodes is small, and domestic problems are prone to occur. You asked the doctor to wear an electron microscope to cut artificial blood vessels, how is this possible?"

This classmate refuted the opponent's point loudly, and the other party was silent for a long time.

The teachers present can finally breathe a sigh of relief. They are non-professionals who do not understand materials science, and can only listen to what the manufacturers say. Now that this classmate said, they have also touched some directions, and the next step can be related to medical research.

Speaking of which, Xie Wanying said these words not just for performance, she had a certain hatred in her heart. To know that she can only recommend friends to choose foreign products after checking the information more than ten years later. The spirit of some domestic manufacturers in making products belongs to the people who are just passing by and do not think about excellence, because they burn too much money. But medicine is very rigorous, and it is impossible to say that medical equipment can be worn casually like a piece of clothing.historical
