Abstract

La présente invention porte sur un dispositif d'anastomose de vaisseaux sanguins, et, plus particulièrement, sur un dispositif d'anastomose de vaisseaux sanguins qui utilise une suture pour effectuer automatiquement une opération d'anastomose de vaisseaux sanguins. Un dispositif d'anastomose automatique de vaisseaux sanguins selon la présente invention comprend une pluralité de raccords d'aiguille, une pluralité de sutures, et un clamp. Les raccords d'aiguille sont installés respectivement sur une extrémité d'un premier vaisseau sanguin et sur une extrémité d'un second vaisseau sanguin, et comprennent une pluralité de saillies élastiques et une pluralité d'aiguilles d'anastomose. Les saillies élastiques sont disposées en réseau à des intervalles constants le long des surfaces externes des premier et second vaisseaux sanguins, et sont pliées à l'extérieur des premier et second vaisseaux sanguins. Les aiguilles d'anastomose s'étendent des extrémités des saillies élastiques aux surfaces externes des premier et second vaisseaux sanguins. Les sutures sont couplées de façon continue à et le long des aiguilles d'anastomose, et réunissent les bordures des premier et second vaisseaux sanguins au moyen d'une rotation des saillies élastiques vers les surfaces externes des premier et second vaisseaux sanguins. Le clamp installe les raccords d'aiguille sur les premier et second vaisseaux sanguins et est ensuite retiré. L'une des sutures est attachée au premier vaisseau sanguin, puis les premier et second vaisseaux sanguins sont reliés l'un à l'autre, puis l'autre des sutures est attachée au second vaisseau sanguin, puis la suture attachée au premier vaisseau sanguin est couplée à la suture attachée au second vaisseau sanguin.
