Abstract

La présente invention concerne un dispositif de serrage et un système de réparation de valve qui appartiennent au domaine technique des instruments médicaux, et peuvent être utilisés pour capturer une valve. Un dispositif de serrage (10) comprend une pince proximale (12), une pince distale (11) et un mécanisme de support (13) ; la pince distale (11) est reliée de manière mobile à la pince proximale (12) et peut se rapprocher de la pince proximale (12) pour serrer une valve, ou s'éloigner de la pince proximale (12) pour former un espace de serrage (15) avec la pince proximale (12) ; le mécanisme de support (13) comprend un élément de support (131) et un élément de commande (132), et l'élément de support (131) est relié de manière mobile à la pince de serrage proximale (12) ; l'élément de commande (132) est relié à l'élément de support (131) pour faire passer l'élément de support (131) d'un état plié à proximité de la pince proximale (12) à un état ouvert supportant la valve ; et la surface extérieure de la pince proximale (12) est pourvue d'un espace de réception (121) utilisé pour recevoir l'élément de support (131) à l'état plié. Le système de réparation de valve comprend le dispositif de serrage. La présente demande vise à résoudre le problème technique posé par la difficulté significative que représente la capture d'une valve dans l'état de la technique.
