Intervention stent capable of preventing massive bleeding, for department of cardiology

Abstract

The invention relates to an intervention stent capable of preventing massive bleeding, for the department of cardiology. The intervention stent comprises bearing pipe bodies, graphene far end diversion openings and graphene near end diversion openings, wherein each bearing pipe body adopts a net-shaped pipe structure of which the axial section is rectangular; each graphene far end diversion opening and each graphene near end diversion opening both adopt the net-shaped pipe structure of which the axial section is an isosceles trapezoid; and the inflow end of each bearing pipe body communicateswith the corresponding graphene far end diversion opening, and the outflow end of each bearing pipe body communicates with the corresponding graphene near end diversion opening. According to the intervention stent disclosed by the invention, on one side, the intervention stent is low in surface area, good in supporting capacity, good in bearing capacity, good in covering power and good in hydrodynamic performance, so that the blood circulation performance in blood vessels can be effectively improved, and the risk of thrombosis can be effectively reduced; and on the other side, the interventionstent is good in tracing performance, small in end head, impermeable to X-ray, good in biocompatibility and good in blood vessel distensibility, so that convenience and precision of detecting and positioning of the stent after a bypass surgery are greatly improved.

Description

technical field [0001] The invention relates to a heart disease treatment device, specifically an interventional support for preventing massive bleeding in the Department of Cardiology. Background technique [0002] Cardiac bypass surgery is an important means of treating heart disease. Cardiac stents are an important treatment device for this type of surgery and are used in a huge amount. However, it has been found during use that current heart stents are often made of metal materials such as stainless steel and nickel alloys. Although it can meet the needs of surgery and disease treatment, the currently used cardiac stents are relatively poor in structural toughness, support, bearing capacity, covering capacity, and fluid mechanics. Increased impact on blood fluidity and passage, and increased risk of thrombus formation, and during surgery, cannot effectively cooperate with surgical activities and other instruments to prevent a large amount of blood loss from damaged blood...

[0002] Cardiac bypass surgery is an important means of treating heart disease. Cardiac stents are an important treatment device for this type of surgery and are used in a huge amount. However, it has been found during use that current heart stents are often made of metal materials such as stainless steel and nickel alloys. Although it can meet the needs of surgery and disease treatment, the currently used cardiac stents are relatively poor in structural toughness, support, bearing capacity, covering capacity, and fluid mechanics. Increased impact on blood fluidity and passage, and increased risk of thrombus formation, and during surgery, cannot effectively cooperate with surgical activities and other instruments to prevent a large amount of blood loss from damaged blood vessels, thus greatly It increases the difficulty and risk of the operation. At the same time, in the treatment of heart disease and follow-up examination, the current cardiac stent has poor ability to disappear and is not easy to be found in the X-ray detection process, which seriously affects the detection efficiency and accuracy, thus seriously affecting the heart bypass surgery. The therapeutic effect of
