Abstract

The invention discloses a new material and preparation method of a coronary stent. The main material of the stent is synthesized from titanium, cobalt, magnesium, nickel and iron, and the adsorption material is composed of sterile cotton and the polyhydroxyalkanoate. Asparagus leaves, Rhododendron azalea, staghorn glue, forsythia, Prunella vulgaris, Corydalis, cicada slough, Lismodium, cat's claw, geranium, pinellia, honeysuckle, Angelica dahurica, gardenia, scutellaria baicalensis, and red peony make up the adsorption drug material , compared with the prior art, the present invention adopts various alloys, which can improve the setting ability of the coronary stent and keep it without deformation. The effect has the value of popularization and application.

Description

technical field [0001] The invention relates to a medical device, in particular to a new material and a preparation method of a coronary stent. Background technique [0002] Cardiac stent, also known as coronary artery stent, is a medical device commonly used in cardiac interventional surgery, which has the function of dredging arteries. Cardiac stents first appeared in the 1980s, and experienced the development of metal stents, coated stents, and soluble stents. The main materials in the prior art are stainless steel, nickel-titanium alloys, or cobalt-chromium alloys. However, in the prior art, the coronary stent can only play a supporting role, but cannot play a therapeutic effect. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a new material and preparation method of a coronary stent in order to solve the above problems. [0004] The present invention achieves the above object through the ...
