栓塞疗法随着介入性放射学的不断发展,钢圈栓(或称不锈钢圈)作为永久性栓塞应用范围越来越广,具有操作简单、使用方便、安全、放置准确、栓塞效果好等优点。 1975年Gianturco等首先应用不锈钢圈进行动物实验和临床应用以来,几经改进,目前已成为经导管血管内栓塞的一种重要栓塞材料。然而,目前国内所采用的都由国外进口,价格昂贵,来源不易。为此,我们通过翻阅文献,研制了一种简易钢圈栓,并经动物实验及临床应用证实安全可靠,易於消毒保存,现将制作方法介绍如下:
Embolization Therapy With the continuous development of interventional radiology, steel ring plugs (or stainless steel rings) have become more and more widely used as permanent embolization. They have the advantages of simple operation, convenient use, safety, accurate placement, and good embolization. In 1975, Gianturco et al. first applied stainless steel rings to animal experiments and clinical applications. After several improvements, it has become an important embolic material for intravascular catheter embolization. However, all the current domestic adoptions are imported from abroad. The prices are expensive and the source is not easy. For this purpose, we have developed a simple steel rim bolt by reading through the literature, and it has been confirmed by animal experiments and clinical applications that it is safe, reliable, and easy to sterilize and preserve. The production method is now described as follows:
