Problems solved by technology

Drug-coated vascular stents are coated with drugs on the surface of the stent, and the drugs will slowly penetrate into the surrounding wall tissue to prevent tissue proliferation and block the blood vessels again. The purpose of treatment has greatly affected the treatment effect. In view of the above defects, it is necessary to design a vascular stent suitable for arteries

Embodiment Construction

[0022] In the following text, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments, however, it will be apparent to those skilled in the art that the described embodiments can be used without these specific details. Some or all instances were practiced, and in other instances well-known process steps were not described in detail.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the vascular stent suitable for arterial blood vessels includes a syringe 11, an expansion balloon 12, and also includes an expansion mechanism and a drug supply mechanism. The drug supply mechanism is composed of a drug supply frame 5, a connecting frame 6 and a reinforcement frame 7, the shape of the frame body 1 is ring-shaped, the number of the beam frame 2 is several pieces, and the beam frame 2 Uniformly surrounds the frame body 1, the beam frame 2 is integrally connected wit...

Abstract

The invention discloses a vascular stent suitable for arterial vessels. The vascular stent comprises an injector and an implanted balloon and further comprises an expanding mechanism and a medicine supplying mechanism. The expanding mechanism is constituted by a stent body, a beam frame, a connecting ring and an elastic frame. The medicine supplying mechanism is constituted by a medicine supplyingframe, a connecting frame and a reinforcing frame. According to the vascular stent suitable for the arterial vessels, the structure is ingenious, and the function is powerful. Firstly, through designof the expanding mechanism, narrow areas of the vessels of a patient can be expanded advantageously by a medical worker, and thus smooth circulating of subsequent blood is guaranteed, secondly through the cooperation effect of the built-in medicine supplying mechanism, medicine can be permeated in surrounding vascular wall tissues slowly, and finally, the situation that the vessels are blocked again due to tissue proliferation is effectively prevented, the therapeutic effect is improved greatly, complications are reduced, and clinical application and popularization are facilitated.

Description

technical field [0001] The invention relates to a stent for blood vessel medical use, in particular to a vascular stent suitable for arterial blood vessels. Background technique [0002] Arteries are blood vessels that transport oxygen-rich blood from the heart to the whole body. If fatty substances such as cholesterol accumulate on the inner walls of the arteries, the diameter of the arteries will gradually narrow and blood will not flow smoothly. If the stenosis occurs in the coronary arteries of the heart, once physical strength or pressure increases and more oxygen and nutrient supply are needed, the narrowed blood vessels cannot respond in real time and increase sufficient blood flow, which will cause myocardial hypoxia such as angina pectoris or shortness of breath Symptoms, and may even lead to acute myocardial infarction or heart failure and death. [0003] Patients with the above-mentioned cardiovascular diseases are currently mainly controlled by drugs after medic...
