Abstract

L'invention concerne un dispositif de suture de vaisseau sanguin à clip, comprenant une pièce de clip montée sur aiguille (1) et une pièce de clip fendue (5) qui sont utilisées par paires. La pièce de clip montée sur aiguille (1) est placée à l'intérieur d'une incision longitudinale (11) d'un vaisseau sanguin (10) ; la pièce de clip fendue (5) est clipsée sur la paroi extérieure du vaisseau sanguin (10) par rapport à la pièce de clip montée sur aiguille (1) ; la pièce de clip montée sur aiguille (1) est pourvue de multiples aiguilles (2) le long des deux côtés de l'incision longitudinale (11) du vaisseau sanguin (10), et les aiguilles (2) sont disposées longitudinalement à intervalles ; la pièce de clip fendue (5) est pourvue de deux rangées de trous traversants longitudinaux (6) correspondant aux aiguilles (2). De multiples paires de pièces de clip montées sur aiguille (1) et de pièces de clip fendues (5) qui sont utilisées par paires sont disposées au niveau des parois interne et externe d'une incision longitudinale (11) d'un vaisseau sanguin (10), et les multiples pièces de clip montées sur aiguille (1) à l'intérieur du vaisseau sanguin et les multiples pièces de clip fendues (5) à l'extérieur du vaisseau sanguin (10) sont toutes suturées de manière imbriquée. Le dispositif de suture de vaisseau sanguin à clip a des effets bénéfiques tels que la diminution de la difficulté d'opération des opérations et le raccourcissement du temps d'opération, et est simple en terme de structure et facile à utiliser.
