The present invention relates to a suture thread for a laparoscopic port site closing apparatus, which is configured such that a cartridge having the suture thread therein is formed at the front end of a needle guide for laparoscopic port site suturing and that the suture thread is threaded through the tip of a needle, which is guided by the needle guide and penetrates biological tissue, so that when the needle is taken out, the suture thread is extracted along an invasion path and tied outside, thereby suturing a laparoscopic port, wherein: a tubular body is configured as a rod body for intubation of the port of a perforated surgical site and has multiple guide grooves, facing one another, for guiding the insertion of the needle； the replaceable cartridge is inserted in the tubular body, has wings, which are spread and folded in a cam manner, at the lower part thereof, and is configured such that the wings are spread by the rotation of and folded by the reverse rotation of an operating rod penetrating the tubular body, the replaceable cartridge being formed at the lower end of the tubular body and attached to/detached from the operating rod； and provided with the wings spread to either side by the operating rod and a compartment having the suture thread therein, the cartridge is configured such that either end of the suture thread is inserted in the wings and that the ends of the suture thread are hooked to a groove of the needle invading from the outside of a body so as to be extracted to the outside of the body.La présente invention concerne un fil de suture pour un appareil de fermeture de site d'accès laparoscopique, qui est conçu de telle sorte qu'une cartouche comprenant à l'intérieur le fil de suture est formée à l'extrémité avant d'un guide d'aiguille pour la suture du site d'accès laparoscopique et que le fil de suture est enfilé à travers la pointe d'une aiguille, qui est guidée par le guide d'aiguille et pénètre dans un tissu biologique, de sorte que lor
