Abstract

La présente invention porte sur un instrument d'insertion d'un élément de fixation. L'instrument peut comporter un arbre ayant une extrémité distale définissant une pointe destinée à venir en prise maniable avec la tête d'un élément de fixation. L'instrument peut comprendre un filament ayant une boucle à proximité de la pointe. La boucle peut définir une ouverture pour capturer la tête de l'élément de fixation et retenir l'élément de fixation sur l'arbre. L'instrument peut également comprendre un dispositif de tension pour appliquer ou relâcher une tension sur le filament afin de changer la dimension de l'ouverture.
