An implement for manipulating a knotted suture (150) during a surgical procedure, includes an elongated shaft (130) having a proximal end engageable by the user for manipulating the instrument, and a distal end engageable with the knotted suture (150) to be manipulated. The distal end (132) of the elongated shaft (13) has an end face (134) formed with a recess (135) for receiving the knot (151) of the suture. The distal end (132) of the elongated shaft (130) is formed with an open slot (133) starting from a location spaced from the end face (134) and leading to the recess (135) in the end face, such as to enable the knotted suture (150) to be introduced into the slot (133) and the recess (135) by effecting a sidewise movement. The implement further includes a tubular cutter member (120) enclosing the elongated shaft (130) and formed with an annular cutting edge (122) engageable with a suture in the open slot (133) of the shaft (130) upon movement of the elongated shaft (130) with respect to the tubular cutter member (120), or by vice-versa.

L'invention concerne un instrument servant à manipuler une suture nouée, pendant une intervention chirurgicale, et qui comprend une tige allongée comportant une extrémité proximale avec laquelle l'utilisateur est en contact pour manipuler l'instrument, et une extrémité distale entrant en contact avec la suture nouée à manipuler. L'extrémité distale de la tige allongée comporte une face d'extrémité dans laquelle est formé un évidement destiné à recevoir le noeud de la suture. L'extrémité distale de la tige allongée comporte une fente ouverte, qui se déploie depuis un point espacé de la face d'extrémité et aboutit à l'évidement, et permet d'introduire par un mouvement latéral la suture nouée dans la fente et l'évidement. L'instrument comprend de plus un élément tranchant tubulaire qui contient la tige allongée et comporte une arête tranchante annulaire pouvant entrer en contact avec la suture dans la fente ouverte de la tige, lorsqu'on déplace la tige par rapport à l'élément tranchant tubulaire, ou vice versa.
