Problems solved by technology

[0003] At present, most vascular stents use a symmetrical or diamond-shaped structure as the basic unit of the stent. This kind of stent has poor radial stiffness, poor axial flexibility, high metal coverage, and a large amount of metal, which leads to postoperative restenosis.

Abstract

The invention discloses a blood vessel opening device for low extremity atherosclerosis, and relates to the technical field of medical instruments. The device comprises a support, the middle of the support is of a circular tube-shaped structure which is formed by multiple basic holes arranged in a staggered mode in an enclosing mode; the two ends of the support are each of a circular tube-shaped structure which is formed by basic holes and auxiliary holes which are staggered in an enclosing mode; each basic hole is formed by two vertical W-shaped support units which are arranged oppositely in an enclosing mode; each support unit is formed by connecting multiple support ribs; each auxiliary hole is of a diamond-shaped structure formed by connecting multiple support ribs. According to the blood vessel opening device for the low extremity atherosclerosis, the radial stiffness can be obviously improved; meanwhile, it is guaranteed that the device has the good axial flexibility and the low metal coverage rate; therefore, the amount of metal can be effectively reduced, and the restenosis rate of the support is lowered; the device has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a blood vessel expansion device for arteriosclerosis of the lower extremities. Background technique [0002] Cardiovascular disease is one of the major diseases threatening human life today. Vascular stent implantation is currently the most important method for the treatment of coronary heart disease caused by vascular stenosis. The main function of the stent is to reshape the blocked blood vessel and maintain its flow. However, in current clinical applications, postoperative restenosis may occur, which seriously restricts the actual curative effect of the vascular stent. The causes of restenosis are complex, and it is generally believed that it is caused by the inflammatory response of blood vessels after stent implantation and the excessive proliferation of smooth muscle cells in blood vessel repair. Therefore, reducing damage and stimulation to blood vessels durin...
