Abstract

The instrument has a rod at a blunt end for transfixing a tendon, where the rod presents a conformation of a non blunt rod with a specific diameter and width in an intermediary part to enable the transfixing of the tendon for maintaining the tendon in a suturing position. The conformation presents a V shape. The rod has a grasping unit at its end and a part (1) presenting angulations to facilitate surgical gesture.

Description

ii

Lors de la réparation des doigts, il est très difficile de réparer les tendons et l'on constate que les praticiens utilisent certains artifices parfois dangereux ou pour eux5 mêmes ou pour leur aide opératoire.  When repairing the fingers, it is very difficult to repair the tendons and it is found that practitioners use certain devices, sometimes dangerous, either for themselves5 or for their operating aid.

C'est ainsi que pour pouvoir recoudre les deux fragments d'un tendon rompu, ils exercent une traction sur ledit élément de tendon et le transfixient au moyen d'une aiguille à injection, de façon à maintenir l'extrémité dudit tendon en dehors du doigt 1o concerné et à pouvoir plus aisément y passer les points de suture nécessaires à cette remise en état.  Thus in order to be able to re-sew the two fragments of a broken tendon, they exert a traction on said tendon element and transfix it by means of an injection needle, so as to keep the end of said tendon outside the finger 1o concerned and to be able more easily to pass the stitches necessary for this repair.

En effet, l'aiguille passée ainsi au travers du tendon ne permet pas, à celui ci de retourner dans le doigt et il reste donc un bout apparent suturable.  Indeed, the needle thus passed through the tendon does not allow the latter to return to the finger and there therefore remains an apparent suturable end.

Néanmoins cette aiguille glisse naturellement et il n'est pas rare de devoir la remettre en bonne position de maintien avant qu'elle ne s'échappe par un effet de recul.  However, this needle slides naturally and it is not uncommon to have to return it to the correct holding position before it escapes through a recoil effect.

Le danger vient donc de la pointe de cette aiguille qui risque donc de s'accrocher au gant ou de piquer le porteur de celui-ci que ce soit le chirurgien ou 20 son assistant.  The danger therefore comes from the tip of this needle which therefore risks catching on the glove or pricking the wearer thereof, whether it be the surgeon or his assistant.

Nous pensons donc qu'il serait préférable d'utiliser un appareil spécial, émoussé, de forme adaptée, qui d'une part retiendrait le tendon en bonne place et d'autre-part, éviterait au praticien de prendre des risques de piqûres toujours 25 préjudiciables on en convient.  We therefore think that it would be preferable to use a special device, blunt, of adapted shape, which on the one hand would hold the tendon in good place and on the other hand, would avoid the practitioner from taking risks of punctures always 25 harmful we agree.

Le dispositif selon la présente invention pourrait donc être représenté par une tige métallique, plate ou cylindrique, à l'extrémité émoussée. {1 Figure 1} et non plus pointue, mais dont le faible diamètre ou la petite largeur, permettrait 30 cependant de transfixier le tendon sans provoquer de déchirure de celui-ci.  The device according to the present invention could therefore be represented by a metal rod, flat or cylindrical, at the blunt end. {1 Figure 1} and no longer pointed, but whose small diameter or small width, would however allow transfixing the tendon without causing it to tear.

Il s'agirait en fait d'un Instrument médical d'aide opératoire comprenant une tige droite à extrémité émoussée permettant de transfixier un tendon, ladite tige présentant, dans une partie intermédiaire, une conformation de tige non droite émoussée, de diamètre ou largeur nécessaire et suffisante pour permettre de transfixier un tendon de façon à le maintenir en position suturable.  It would actually be an operating aid medical instrument comprising a straight blunt end rod for transfixing a tendon, said rod having, in an intermediate part, a non-straight blunt rod conformation, of necessary diameter or width. and sufficient to allow a tendon to be transfixed so as to maintain it in a suturable position.

Pour éviter que ce mandrin de maintien ne se déplace durant l'intervention, on peut imaginer qu'à un certain endroit de sa longueur, une déformation, triangulaire,{2 Figure 1} conique, ou cylindrique,{1 Figure 2} soit pratiquée pour que, cette forme, une fois en face du site du tendon, ne tende qu'à io rentrer dans le fragment de doigt concerné et donc, venant en appui, ne puisse plus se déplacer longitudinalement.et de ce fait empêcher le tendon de retourner dans le doigt durant la suture. Il s'agirait en fait d'un instrument médical dont la la conformation présenterait une forme en 'V".ou une forme arrondie incurvée.  To prevent this holding mandrel from moving during the intervention, we can imagine that at a certain point along its length, a triangular, {2 Figure 1} conical, or cylindrical, {1 Figure 2} deformation is practiced so that this shape, once opposite the site of the tendon, only tends to enter the fragment of finger concerned and therefore, coming to bear, can no longer move longitudinally and thereby prevent the tendon from return to the finger during suturing. It would in fact be a medical instrument whose conformation would have a "V" shape or a curved rounded shape.

Pour des raisons de pratique de mise en place, on peut même envisager que ladite tige comprenne à une extrémité un moyen de préhension à l'opposé de l'extrémité émoussée, {3 Figure 1 - 2 Figure 2}améliorant ainsi la préhension dudit matériel.  For reasons of practical implementation, we can even consider that said rod comprises at one end a gripping means opposite the blunt end, {3 Figure 1 - 2 Figure 2} thus improving the grip of said material .

De même, pour des raisons évidentes de gestuelle chirurgicale, on peut très bien envisager également qu'une partie, coté opposé à l'extrémité émoussée de l'instrument, soit angulée ou cintrée de plusieurs degrés {1 Figure 3} de façon à s'effacer devant la trajectoire des membres du chirurgien ou de son aide.  Likewise, for obvious reasons of surgical gestures, it is also very possible to envisage that a part, on the side opposite the blunt end of the instrument, be angled or bent by several degrees {1 Figure 3} so as to s 'erase in front of the path of the surgeon's members or his assistant.
