Returning to ’90s, She Became Famous in Major Surgical Fields Chapter 2648: 【2648】Market decision

   Chapter 2648 [2648] Market Decision

  Polyester is the first material used in the manufacture of artificial blood vessels. The safety of dical polyester and dical sutures to stay in the human body for a long ti can stand the test. Its biggest problem is that its anticoagulation is not good, it needs anticoagulation pretreatnt, and it needs to be coated with a biological coating.

  ePTFE is the expansion body of PTFE, commonly known as the king of plastics, which is equivalent to a new product made of PTFE based on a special process. In contrast, ePTFE performs very well in anticoagulation, and has good biocompatibility in the human body. The rejection reaction is very light, and it is not easy to degrade like polyester. It can be used in the human body for a long ti without frequent replacent. . Compared with polyester, there is no need for anticoagulation pretreatnt and no biological coating. These conveniences make it widely praised in clinical practice.

   Does the new generation of artificial blood vessel star material really have no shortcomings at all? There is nothing in the world that is safe and perfect. It is impossible for dical devices to be the sa as the human body's own long tissues and organs.

The shortcomings of ePTFE, which have been summarized in international research papers, are always inferior to the elasticity of the human body's own blood vessels, and its softness is sowhat worse than that of the human body, which causes blood to flow in it for a long ti, and it is easier to form at the anastomosis over ti. A blood clot causes a blockage.

  This kind of device material is a very test of the technical level of the surgeon.

  If a surgeon is highly skilled, he may be able to help the patient handle this artificial vascular anastomosis better, and it has a low probability of blockage, even if it occurs, it will delay the ti point. If the surgeon's technique is average, the consequences are needless to say.

Can    require all surgeons to be highly skilled?

impossible. The supply and demand for exceptionally good surgeons has always been out of balance.

It is like inventing a smartphone. It must have enough foolish operation thods for most people to use it. If it is made into a complicated operation that only coders can use, it will beco sothing that is not for the general public. Can't sell it.

  In the dical material market, it becos: the dical surgical materials created must et the technical level of most surgeons, not the technical level of big cattle.

   If you simply use the technical level of Daniel to make dical equipnt, it is destined to not be promoted, and even clinical trials will not pass the test, because the results of clinical trials will be terrible. For example, one of the clinical trial indicators of this artificial blood vessel is called the long-term vascular patency rate. The operation perford by Daniel may make this material perform well in this index, reaching 80 to 90 percent after half a year, while a surgeon with a general technical level can only reach 40 to 50 percent unqualified.

  The results of the test are subject to surgeons with general technical skills. Seeing this clinical test value, all clinicians and researchers will beco two big.

   To sum up, ePTFE has its shortcomings, but since it has been affird in the production of artificial blood vessels internationally. Again, the bad ratio should be controlled within a controllable range and should not be exceeded.

   Now it can only beco a question of choosing one of two. Or is this material not good? Or is there an indescribable contradiction between this surgical technique and the new product?

  The teachers at the conference table had solemn expressions and asked each other. First determine whether these problematic cases are widespread in various hospitals.
