Abstract

La présente invention concerne un cathéter de thrombolyse et un ensemble cathéter de thrombolyse. Selon la présente invention, lorsqu'un fil-guide universel est inséré dans le cathéter de thrombolyse, le fil-guide universel peut bloquer une entrée du bouton de fixation et une sortie du segment fermé, et un espace d'administration de médicament est formé entre la paroi interne du segment de travail et le fil-guide universel. C'est-à-dire que le cathéter de thrombolyse de la présente invention peut utiliser un fil-guide universel, sans avoir besoin d'utiliser un fil-guide non universel relativement coûteux, afin d'atteindre l'objectif d'une administration de médicament sans problème, ce qui réduit le coût d'un ensemble cathéter de thrombolyse pendant le traitement clinique de la thrombose, ce qui permet de réduire le coût du traitement clinique de la thrombose.
