The market size is small, without data accumulation, manufacturers, clinicians, what to use to study products. It is useless to compare abroad and I don’t know what to compare. I only know how to blow holes.
From the beginning, Student Xie is aimed at the essence of this blow, so don’t be led by someone easily. She has relevant data from the future. The research report she made after the number of cases in China increased to a certain amount gives some essence.
It points to why domestic products are worse than foreign ones.
"The maximum pore diameter abroad can be 80 microns, with an average of more than 50 microns. This is a small artificial blood vessel. You can also say that it is okay to do it if you want to do it, but you have to do it by 80, which is to do it by doing
If they don’t have the small artificial blood vessels, they are made of large artificial blood vessels, which rely on large ones. In other words, the production process is different. The domestic product stretching is several times that of foreign countries.”
The expansion body is pulled out and sintered.
The manufacturer's people stared at her face with their eyes: Are you a doctor? Are you sure you are just a doctor?
It's really just a doctor. Xie Wanying told the other party carefully about the key points of artificial blood vessels in the eyes of doctors: "The most challenging thing about artificial blood vessels is not large-diameter, but small-diameter tubes that are small to a certain extent."
The difficulty of large-diameter pipes and small-diameter pipes is the strength, and we are afraid that the strength is not enough. Large-diameter pipes can be stacked hard to increase the strength. Small-diameter pipes that are as small as small do not have this shortcut to tensile strength. Looking around the world
All are difficult projects, and it is even more difficult for the artificial vascular industry that has just started in China.
As soon as the teachers discussed today, she immediately realized that the small-diameter tube was talking about. Why, 1. Teacher Fu did not mention the recent surgery case of Yaxi's mother. The latest application case meets the requirements and can be taken out at the meeting.
Speaking of 2. It matches the problems that appear in the anastomosis and matches the problems revealed in scientific research reports she has seen in the future.
"When our surgeons do surgical suture, the needle and thread footing point is within an area approximately 2mm from the mouth of the tube. What determines the fixing position of the suture is the crystallinity of the material, the width of the nodes and fiber length in the material, etc., not the single hole diameter.
Relationship. Crystallization degree. Comparison of domestic products. Have you done data abroad? The longer the fiber length, the smaller the node width, the smaller the strength will become. Foreign products make uniform nodes, and some have large pore diameters and shorter fibers. Do you not use domestic technology?
I admit it when speaking, to achieve a large aperture, the longer the fibers should be pulled. During the operation, if the doctor just cut the worst node with scissors, the problem of relatively uniform nodes abroad is small, and problems are prone to problems in China.
How is this possible if you ask the doctor to wear an electron microscope to cut the artificial blood vessels?”
This classmate refuted the other party’s point, and the other party was silent for a long time.
All the teachers present could finally breathe a sigh of relief. They don’t understand materials learning, but they can only listen to the manufacturers. Now, when this classmate says, they have also found some directions, and the next step can be related.
Medical research.
To be honest, Xie Wanying said these words not just for the sake of expressing her feelings, and she felt that she was disappointed. You should know that she could only recommend her friends to choose foreign products after checking information more than ten years ago. Some domestic manufacturers are just trying to make products.
