Description

一种心脑血管支架的制备方法
技术领域
本发明涉及血管支架技术领域，具体而言，涉及一种心脑血管支架的制备方法。
背景技术
血管类疾病严重危害人类身体健康，全球每年都有数以万计的人由于血管老化、损伤、病变等多方面原因患有血管类疾病。
目前，心脑血管常见的疾病主要有动脉狭窄、动脉瘤等，这些疾病若不及时治疗可能会导致血管堵塞、瘤体破裂，将严重危害人类的生命安全。目前支架介入术是治疗心血管疾病的主要手段之一，介入材料与人体组织相互作用研究，越来越引起人们的关注，所谓的人体组织是指血管、骨质、器官和体液等。临床上广泛使用的血管支架主要有金属裸支架和药物洗脱支架。
发明内容
本发明的目的在于提供一种心脑血管支架的制备方法，以解决现有技术中的不足。
为实现本发明目的，采用的技术方案为：
一种心脑血管支架的制备方法，其特征在于，包括以下步骤：
(1) 配备原料：该心脑血管支架中的合金成分的重量百分比为锆2％～3％，钼1％～3％，铌4％～5％，其余为镁和钛，其中镁和钛的重量比为2∶1；
（2） 制备支架基体：注射成形机的模具中直接注射形成，制备得所述支架基体；
（3） 聚合物溶液的制备：将无水乙醇和氢氟酸混合，搅拌至均匀，再加入钛酸四丁酯混匀得溶液，其中氢氟酸浓度为0.2～0.3mol/L，钛酸四丁酯浓度为0.15～0.25mol/L；向该溶液中加入其1/100～1/50体积的去离子水溶液，该去离子水溶液中溶有氟化盐，其浓度为0.2～0.3mol/L；
（4） 将支架基体放入步骤(3)制备的聚合物溶液中，水热反应12～15h，取出支架基体，用去离子水冲洗干净，干燥，在支架基体表面形成涂层。
本发明的有益效果是，
本发明大幅度提高了血管支架的抗腐蚀性能、屈服强度和塑性，而且满足了临床对血管支架消溶速度及时间要求，消除了血管硬化的问题，同时还具有较高的安全性和可靠性。
具体实施方式
下面通过具体的实施例子对本发明做进一步的详细描述。
