Abstract

La présente invention concerne un instrument de suture qui permet de suturer de manière hygiénique et pratique une zone affectée incisée de façon à améliorer la fiabilité. L'instrument de suture de la présente invention est caractérisé en ce qu'il comprend : un film de suture auquel une suture comprenant une partie traction et une partie boucle est attachée de façon détachable ; un corps ayant une fente de guidage pour guider le transfert du film de suture ; et une aiguille de suture qui tire une partie traction de suture du film de suture transféré le long de la fente de guidage du corps et tourne pour pénétrer dans la partie boucle à travers une zone affectée. De plus, l'instrument de suture de la présente invention peut éventuellement utiliser : un élément d'entraînement qui fait tourner l'aiguille de suture et transfère également le film de suture ; un élément de maintien pour maintenir la partie traction qui a pénétré dans la partie boucle de la suture de façon à lier un noeud ; et un élément de coupe pour couper la suture nouée. En conséquence, la présente invention a un effet dans lequel il est possible d'utiliser sélectivement, par une opération simple, la fonction de suture d'une zone affectée, la fonction de maintien d'une suture de manière à lier un noeud, la fonction de découpe d'une suture nouée, et analogue, selon les besoins.
