Provided is a suturing device that can easily and accurately form a knot or a seam by means of mechanical action that is based on a simple operation. The present invention includes: a needle 30 that holds a first string-shaped member L1 and that is capable of reciprocal movement in a prescribed direction； a shuttle 26 that has a holding part 62, which holds a second string-shaped member L2, that has a first hook-shaped end part 64 and a second hook-shaped end part 66 that are provided on either side of the holding part 62, and that can rotate in both directions around a line (a center axis line C1) that is parallel to the direction of the reciprocal movement of the needle 30. As a result of having the first hook-shaped end part 64 and the second hook-shaped end part 66 that are provided on either side of the holding part 62 and of being able to rotate in both directions around the line (the center axis line C1) that is parallel to the direction of the reciprocal movement of the needle 30, the shuttle 26 sequentially passes the holding part 62 from both directions through a loop LP that is formed by crossing of the needle 30 and can thereby make the loop LP and the second string-shaped member L2 that is held by the holding part 62 cross each other.L'invention concerne un dispositif de suturage qui peut facilement former un nœud ou une couture avec précision au moyen d'une action mécanique qui se base sur une opération simple. La présente invention comprend : une aiguille 30 qui retient un premier élément L1 en forme de chaîne et qui est capable d'un mouvement de va-et-vient dans un sens prescrit； une navette 26 qui comporte une partie retenue 62, qui retient un second élément L2 en forme de chaîne, et comprend une première partie d'extrémité 64 en forme de crochet et une seconde partie d'extrémité 66 en forme de crochet situées de part et d'autre de ladite partie retenue 62, et qui peuvent effectuer un mouvement de rotation dans les deux sens autour d'une ligne (lign
