Abstract

The invention provides a testing device for the bending performance of vascular stents. The testing device for the bending performance of the vascular stents comprises a base, and mounting brackets are slidably arranged on the base. The mounting bracket comprises the first mounting bracket for placing the one of the vascular stents and the second mounting bracket for placing the vascular stents, and a testing mechanism for driving the vascular stents to bend is further arranged on the base. According to the testing device for the bending performance of the vascular stents, the bending fatiguetesting of the vascular stents is achieved, the bending performance of the different vascular stents is compared, multiple groups of testing and a single group of testing can be performed at the sametime, and the bending life testing of the vascular stents can further be realized.

Description

technical field [0001] The invention relates to a bending test device for the fatigue performance of a vascular stent, which is a biomedical experiment device. Background technique [0002] Atherosclerosis is the most common and most important of a group of arteriosclerotic vascular diseases, and interventional stents are a very common and highly effective treatment for occlusive atherosclerosis. Although vascular stents have been greatly developed in terms of their configuration, materials, placement process, and postoperative antithrombotic drug therapy, the high incidence of postoperative intravascular restenosis and late thrombosis still affects the development of vascular stents. with its therapeutic effect. Studies have found that better stent flexibility and good bending performance can greatly reduce the risk of surgery in complex and twisted blood vessels. Contents of the invention [0003] In order to measure the bending performance of the vascular stent, the p...
