An implement for manipulating and cutting a knotted suture includes a body member having a handle at one end, and a knot-engageable section at the opposite end for engaging the knotted suture to be cut; and a cutting member carried by the body member and having an end portion formed with a cutting edge for cutting the knotted suture at a predetermined distance from the knot. The cutting member is movable along its longitudinal axis from a normal position to an actuated position for cutting the knotted suture. The knot- engageable section of the body member is formed with an axial bore for receiving the end portion of the cutting member when the cutting member is moved to its actuated position, and with an angled bore intersecting the axial bore at an angle to the longitudinal axis for receiving the knotted suture. The knot is located at one side of the angled bore and the suture to be cut extends through the angled bore to the opposite side, such as to permit hand- tensioning the knot and then cutting the suture by moving the cutting member to its actuated position.

Cette invention se rapporte à un instrument servant à manipuler et à couper des sutures nouées et comprenant à cet effet un élément de corps comportant un manche à l'une de ses extrémités et une section de saisie de noeud à l'autre extrémité, servant à saisir la suture nouée devant être coupées ; ainsi qu'un élément de coupe maintenu par l'élément de corps et possédant une partie terminale pourvue d'un tranchant destiné à couper la suture nouée à une distance prédéterminée du noeud. L'élément de coupe peut se déplacer le long de son axe longitudinal d'une position normale jusqu'à une position activée, en vue de couper la suture nouée. La section de saisie du noeud de l'élément de corps présente un passage axial destiné à recevoir la partie terminale de l'élément de coupe lorsque celui-ci est déplacé dans sa position activée, et un passage incliné coupant le passage axial selon un angle par rapport à l'axe longitudinal, en vue de recevoir la suture nouée. Le noeud est placé sur un côté du passage incliné et la suture à couper traverse ce passage incliné jusqu'au côté opposé, de façon à permettre au chirurgien de tendre le noeud avec la main et de couper ensuite la suture, en déplaçant l'élément de coupe jusque dans sa position activée.
