一种血管介入导管
本技术属于医疗器械
,特别是涉及一种介入导管。
技术介绍
对血管内疾病进行介入治疗是近年来新兴的
,其中介入导管是实施该项技术的关键医疗器械之一。在进行血管介入治疗时,首先是用穿刺针在血管上穿刺,然后将介入导管穿入血管内,再将导丝从介入导管尾部的锥形口插入介入导管,建立一个从穿刺点直至靶血管处的轨道,将介入导管沿着导丝向前推进直到靶血管处,最后抽出导丝即可利用该介入导管进行下一步的检查和治疗工作了。目前的介入导管主要是由导管体和导管柄构成,在导管管腔的尾部设置了一个密封圈,密封圈是由柔软的橡胶制成,密封圈的内径明显小于导管其它部位的管腔内径,也略微小于导丝的外径,密封圈的作用是当导丝穿入导管之后,密封圈可以防止血液从导管的尾部流出。在进行介入插管时当导管进入到某一血管段之后,如果要想确定导管是否进入到预想的靶血管段时,就需要将导丝抽出,然后把注射器插接在介入导管尾部的锥孔处,经导管向血管内注入造影剂进行观察。如果导管插入的位置不合适,还需要重新插入导丝继续移动导管,可以看出这样的操作非常繁琐。而且,在将导丝抽出之后导管还容易从已经插入 ...
