Carotid artery bracket for rapamycin drug eluting

Abstract

The invention discloses a carotid artery bracket for rapamycin drug eluting. The bracket comprises a first expanding bar and an internal support bar, wherein the internal support bar is fixedly connected with a fixed pusher plate, the side face of the fixed pusher plate is fixedly connected with a thrust wire, the other end of the thrust wire is fixedly connected with a sliding pusher plate, the top of the sliding pusher plate is hinged to a dilation pusher bar, the other end of the dilation pusher bar is hinged to the side face of the first expanding bar, a drug loading box is arranged on the internal support bar, one end of the first expanding bar is hinged to a second expanding bar, and the side face of the second expanding bar is hinged to an internal wall support bar. According to the carotid artery bracket for rapamycin drug eluting, through arranging the fixed pusher plate, the thrust wire, the sliding pusher plate, the first expanding bar, the second expanding bar and the internal wall support bar, an adjustable supporting effect can be achieved during use; and through heating modes such as hot compress, a contracted blood vessel is effectively supported again, and influence on health of a sufferer caused by postoperative blood vessel restenosis is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rapamycin drug-eluting carotid artery stent. Background technique [0002] Cardiovascular disease represented by coronary atherosclerosis is currently the greatest threat to human health. According to relevant statistics, millions of people in my country suffer from coronary heart disease and other vascular stenosis diseases every year. At present, the commonly used treatment methods include oral drug treatment, surgical treatment and interventional treatment. Among them, cardiac interventional therapy represented by percutaneous transluminal angioplasty (PTCA) and stent implantation has the advantages of small trauma, fast recovery, and can deliver drugs to the lesion in a targeted manner, which enhances the effect of drug therapy and reduces the systemic risk of drugs. The advantages of toxicity and side effects have become the most promising treatment for coronary h...
