Abstract

The invention relates to an interventional stent for preventing massive bleeding in the Department of Cardiology, which includes a bearing tube body, a graphene distal diversion port, and a graphene proximal diversion port. The carrier tube body is a mesh tube structure with a rectangular axial section. The graphene distal diversion port and the graphene proximal diversion port are both mesh tube structures with an isosceles trapezoidal axial section. The proximal port is connected. On the one hand, the present invention has small surface area, good supporting force, bearing capacity, covering capacity and hydrodynamic performance, can effectively improve the blood circulation performance in blood vessels, and can effectively reduce the risk of thrombus formation; on the other hand, it has good traceability and small end , X-ray opaque, biocompatibility, and good vasodilation performance, thus greatly improving the convenience and accuracy of stent detection and positioning after heart bypass surgery.

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] Heart bypass surgery is an important means of treating heart disease. The interventional stent for preventing massive bleeding in the internal medicine department of the center is an important treatment device for this type of operation. It is used in a huge amount. They are usually made of metal materials such as stainless steel and nickel alloys. Although they can meet the needs of surgery and disease treatment, the structural toughness, supporting capacity, bearing capacity, and Covering ability and hydrodynamic performance are relatively poor. At the same time, after being implanted in the human body, the blood flow and passage will be greatly affected, and the risk of thrombosis will easily increase. During the operation, it cannot effectively communicate wi...

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] Such as figure 1 The interventional stent for preventing massive bleeding in the Department of Cardiology includes a carrying tube body 1, a graphene distal diversion port 2, and a graphene proximal diversion port 3, and the carrying tube body 1 is a mesh with a rectangular axial section. Shaped tube structure, the graphene distal diversion port 2 and the graphene proximal diversion port 3 are both mesh tube structures with an isosceles trapezoidal axial cross-section, carrying the inflow end of the tube body 1 and the graphene distal diversion port 2 connected, the outflow end communicates with the graphene proximal diversion port 3, and the carrying tube body 1, the graphene distal diversion port 2, and the graphene proximal diversion por...
