Abstract
Description
La présente invention concerne une aiguille de suture médicochirurgicale du type comprenant une partie formant la pointe de l'aiguille, le cas échéant pourvue d'arêtes coupantes, et une partie de retenue du fil. The present invention relates to a medico-surgical suture needle of the type comprising a part forming the tip of the needle, optionally provided with cutting edges, and a thread retaining part.
Les aiguilles de suture de ce type, qui sont connues sont des aiguilles monobloc, par exemple à chas ouvert et ainsi semblables aux aiguilles de coutière,Cu à chas fermé obtenu par écrasement de l'extrémité et par formage ou à chas foré obtenu par perçage mécanique. Suture needles of this type, which are known, are monobloc needles, for example with open eye and thus similar to cutlery needles, Cu with closed eye obtained by crushing the end and by forming or with drilled eye obtained by drilling mechanical.
Ces différentes aiguilles connues ont pour inconvé nieni majeurs la discontinuité entre l'aiguille et le fil dans le cas du chas ouvert, qui entrasse des blessures au niveau d'une suture, ou la formation de micro-fissures dans le cas des chas roulés ou percés, qui sont la conséquence du choix du matériau fait en priorité pour obtenir des bonnes qualités coupantes. These various known needles have the major drawback of the discontinuity between the needle and the thread in the case of the open eye, which collects wounds at the suture, or the formation of micro-cracks in the case of the rolled eyes or drilled, which are the consequence of the choice of material made in priority to obtain good cutting qualities.
La présente invention a pour objectif de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Pour atteindre ce but, l'invention propose une aiguille de suture du type décrit plus haut, qui est caractérisée en ce qu'elle est formée par l'assemblage de deux éléments séparés formant respectivement les deux parties de fonction différente de l'aiguille. To achieve this object, the invention provides a suture needle of the type described above, which is characterized in that it is formed by the assembly of two separate elements respectively forming the two parts of different function of the needle.
Selon une caractéristique avantageuse de l'invention, les deux éléments sont avantageusement réalisés en des matériaux différents appropriés chacun à la fonction que l'élément respectif doit accomplir. According to an advantageous characteristic of the invention, the two elements are advantageously made of different materials each suitable for the function that the respective element must perform.
Selon encore une autre caractéristique avantageuse de l'invention, l'élément de retenue du fil est conformé en élément de sertissage du fil à partir d'une pièce tubulaire. According to yet another advantageous characteristic of the invention, the wire retaining element is shaped as a wire crimping element from a tubular piece.
Il est avantageux selon la présente invention, d'assembler les deux éléments par soudage ou brasage bout en bout, par collage ou par rétreint. It is advantageous according to the present invention to assemble the two elements by welding or brazing end to end, by gluing or by shrinking.
L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparattront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention et dans lesquels
- la figure 1 est une vue en coupe axiale partielle d'une aiguille de suture médicochirurgicale selon la présente invention ; et
- les figures 2, 3 et 4 illustrent en des vues en coupe axiale, avec arrachement, trois modes d'assemblage des deux éléments constitutifs de l'aiguille de suture suivant la figure 1. The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating several modes. of the invention and in which
- Figure 1 is a partial axial sectional view of a medico-surgical suture needle according to the present invention; and
- Figures 2, 3 and 4 illustrate in axial section views, with cutaway, three modes of assembly of the two components of the suture needle according to Figure 1.
Comme le montre la figure I, l'aiguille de suture médicochirurgicale selon l'invention est formée par l'assemblage de deux éléments séparés, un élément coupant 1, c'est-à-dire comprenant les arases coupantes et un élément tubulaire 2 de sertissage du fil (non représenté). As shown in Figure I, the medico-surgical suture needle according to the invention is formed by the assembly of two separate elements, a cutting element 1, that is to say comprising the cutting edges and a tubular element 2 of wire crimping (not shown).
L'élément i est réalisé en un matériau qui a été choisi en égard à la fonction que cet élément doit accomplir, c'est-à-dire pour pouvoir obtenir des ar#tes coupantes de bonne qualité. L'élément de sertissage 2 du fil est en un matériau susceptible d'etre serti sans que des micro-fissures se créent. Il est à noter que les critères suivant lequel le choix des matériaux des deux éléments est fait sont en général incompatibles. C'est cette incompatibilité qui est à l'origine des inconvénients des aiguilles de suture connues. The element i is made of a material which has been chosen with regard to the function that this element must fulfill, that is to say in order to be able to obtain cutting edges of good quality. The crimping element 2 of the wire is made of a material capable of being crimped without micro-cracks being created. It should be noted that the criteria according to which the choice of materials for the two elements is made are generally incompatible. It is this incompatibility which is the source of the disadvantages of known suture needles.
Les deux éléments de l'aiguille de suture selon l'invention peuvent ventre assemblés de multiples manières. The two elements of the suture needle according to the invention can belly assembled in multiple ways.
Les figures 2 à 4 illustrent trois modes d'assemblage particulièrement avantageux. Figures 2 to 4 illustrate three particularly advantageous assembly methods.
Suivant la figure 2 les éléments I et 2 sont assemblés bout à bout, par soudage ou brasage, à l'aide de tout moyen approprié, par exemple par laser, résistance électrique, induction, micro-plasma, bombardement électronique. According to Figure 2 the elements I and 2 are assembled end to end, by welding or soldering, using any suitable means, for example by laser, electrical resistance, induction, micro-plasma, electronic bombardment.
La figure 3 montre l'assemblage par collage des deux éléments 1 et 2. A cette fin l'élément coupant 2 est pourvu à son extrémité arrière d'une partie cylindrique de plus faible diamètre 3 sur lequel est emmanché l'élément tubulaire de sertissage 2. Figure 3 shows the assembly by gluing of the two elements 1 and 2. To this end the cutting element 2 is provided at its rear end with a cylindrical part of smaller diameter 3 on which is fitted the tubular crimping element 2.
Suivant la figure 4 11 assemblage des éléments 1 et 2 est réalisé par rétreint. Préalablement à l'opération d'assemblage, l'extrémité arrière, c'est-à-dire non pointue de l'élément coupant I et qui forme le corps de l'aiguille a été adoucie par un traitement thermique, pour pouvoir conférer à cette extrémité la forme représentée, c'est-à-dire pour pouvoir obtenir à partir d'une partie initiale cylindrique du diamètre d une partie extrême coaxiale de plus faible diamètre 4 permettant l'emmanchement de l'élément de sertissage de fil tubulaire 2. According to Figure 4 11 assembly of elements 1 and 2 is achieved by shrinking. Prior to the assembly operation, the rear end, that is to say the pointed end of the cutting element I and which forms the body of the needle, has been softened by a heat treatment, in order to be able to impart to this end the shape shown, that is to say to be able to obtain from an initial cylindrical part of the diameter of an extreme coaxial part of smaller diameter 4 allowing the fitting of the crimping element of tubular wire 2 .
il va de soi que de multiples modifications peuvent astre apportées à l'aiguille de suture représentée et décrite ci-avant. La forme de l'élément coupant pourrait entre différente, aussi bien au niveau de la pointe que dans sa partie arrière destinée à etre reliée à 11 élément de sertissage du fil. Ce dernier peut avoir toute autre forme appropriée. Les moyens d'assemblage des deux éléments ne sont pas limités à ceux décrits plus hauts et peuvent Entre de toute nature appropriée. It goes without saying that multiple modifications can be made to the suture needle shown and described above. The shape of the cutting element could between different, both at the tip and in its rear part intended to be connected to the wire crimping element. The latter may have any other suitable form. The means of assembling the two elements are not limited to those described above and can be of any suitable nature.
