Abstract

The invention discloses an intraoperative branched on-demand block stent type artificial blood vessel system and a use method. The intraoperative branched on-demand block stent type artificial blood vessel system comprises an artificial blood vessel main body, a branched covered stent, a branched blocking device and a releasing device, wherein the branched blocking device is positioned around a joint between the artificial blood vessel main body and the branched covered stent or positioned in the cavity of the branched covered stent; the branched blocking device is separably connected with the artificial blood vessel or the branched covered stent, so that communication control between aortic vascular and branch vessels can be realized. By using the intraoperative branched on-demand block stent type artificial blood vessel system and the use method, the blocking and communication of the aortic vascular and the branch vessels on an aortic arch can be controlled as required, the dissociation, blocking or fitting and the like of the branch vessels on the arch is reduced or avoided, surgical operation is simplified greatly, and injury of blood vessels and peripheral tissues are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to the technology of medical devices used in cardiovascular surgery. Background technique [0002] Aortic disease is a group of cardiovascular diseases that seriously threaten human health, mainly including aortic dissection and aortic aneurysm. Among them, aortic dissection is a catastrophic disease. If it is not treated in time, the prognosis is extremely dangerous. According to reports, the early mortality rate of untreated aortic dissection increased by 1% per hour, and more than 50% of patients died within 1 week. In recent years, with the aging of the population, the increasing incidence of hypertension / arteriosclerosis, and the advancement of non-invasive medical imaging technology, the detection rate of such diseases has been increasing year by year. However, at present, the development of medical care in my country is uneven, and only a few hospitals can carry out surgical ...
