Abstract

The invention relates to a test device for the bending performance of a vascular stent, comprising a base, on which a mounting frame is slidably provided, and the mounting frame includes a first mounting frame for placing a single vascular stent and a second mounting frame for placing several vascular stents. The mounting frame, the base is also provided with a testing mechanism for driving the bending of the vascular stent. The invention realizes the bending fatigue test of the vascular stent, compares the bending properties of different vascular stents, can simultaneously perform multi-group tests and single-group tests, and realizes the bending life test of the vascular stent.

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...
