New artificial blood vessel is more effective in treating acute thrombosis
Science and Technology Daily, Moscow, August 10 (Reporter Dong Yingbi) According to a recent report by the Russian "Izvestia", researchers at the Tomsk University of Technology in Russia put polyvinyl lactone into the discharge plasma of a magnetron and developed a A new type of artificial blood vessel manufacturing technology that can better treat acute thrombosis. This method is more effective and higher quality than similar technologies, and the price is only one-tenth of that of similar technologies. The relevant research results were published in the journal "Applied Surface Science".
As we all know, artificial blood vessel is a kind of graft, currently used to treat acute thrombosis. In the case where the blood vessel function cannot be restored through drugs or surgery, the place where the thrombus occurs needs to be removed and replaced with an artificial blood vessel made of polycarbonate or other biocompatible materials.
In order to improve the survival rate of transplanted blood vessels, the process currently used is extremely complicated and the drugs are also very expensive. However, according to medical experts, the current artificial blood vessel technology and its functional characteristics still have many shortcomings.
Yevgeny Borbasov, a researcher at the Plasma Hybrid System Laboratory of Tomsk University of Technology, said that the main advantage of the artificial blood vessel they studied is that the outer layer of the blood vessel can be fully softened by water, making the artificial blood vessel easy to survive in the body. . The inner layer of the artificial blood vessel cannot be softened by water, which can ensure the best blood flow.
It is reported that for the first time, researchers from Tomsk University of Technology proposed to use polyvinyl lactone treated with magnetron discharge plasma to make artificial blood vessels. This technology can simultaneously ensure that artificial blood vessels have two key characteristics: material and patient High-quality combination of organization and high air tightness.
Sergey Tverdochrepov, head of the Plasma Hybrid System Laboratory of Tomsk University of Technology, said that the uniqueness of this new domestic technology is that it is simpler than the existing artificial blood vessel manufacturing method, and The cost is only one-tenth that of similar technical methods.
According to reports, researchers plan to first test the developed grafts on animal living tissues.
