Description

DISPOSITIF DE BOBINAGE DE FIL DE SUTURE SUTURE THREAD WINDING DEVICE
L'invention concerne les dispositifs d'emballage automatique de fils de suture.The invention relates to automatic packaging devices for sutures.
Les emballages courants de fils de suture et notamment de fils de suture montés sur une aiguille, sont constitués de flancs cartonnés plies de manière à maintenir le fil fermement à l'intérieur de l'emballage. Ces emballages cartonnés, couramment appelés navettes, présentent en général une zone fragilisée telle qu'une pré-découpe prévue pour qu'un praticien arrache facilement cette zone et découvre une partie choisie de l'aiguille ou du fil.Common packages of suture threads and in particular suture threads mounted on a needle, consist of cardboard sides folded so as to hold the thread firmly inside the package. These cardboard packaging, commonly called shuttles, generally have a weakened area such as a pre-cut provided for a practitioner to easily tear off this area and discover a selected part of the needle or thread.
Dans les emballages actuels, on veille à disposer le fil de suture de telle façon qu'une traction sur une zone choisie du fil provoque une sortie progressive du fil sans qu'il ne s'emmêle sur lui-même ou plus généralement qu'un nœud apparaisse.In current packaging, care is taken to arrange the suture in such a way that a pull on a selected area of the thread causes a progressive exit of the thread without it becoming tangled on itself or more generally than a knot appears.
Pour éviter un tel incident, le fil est habituellement déposé sur le support en décrivant des huit successifs, de sorte que le fil forme des croisements successifs superposés au centre de la bobine en huit, qui ont pour effet de réduire efficacement le risque d'emmêlage du fil lorsqu'il est tiré hors de l'emballage.To avoid such an incident, the wire is usually deposited on the support, describing successive eight, so that the wire forms successive crossings superimposed on the center of the reel in eight, which have the effect of effectively reducing the risk of tangling. wire when pulled out of the package.
D'autres enroulements particuliers du fil sur la navette, aptes à empêcher l'apparition de nœuds, sont également possibles. Pour placer le fil selon ces enroulements particuliers, on prévoit des machines de bobinage aptes à décrire la forme choisie et à décharger le fil sur le support de manière progressive au cours du trajet choisi.Other particular windings of the wire on the shuttle, capable of preventing the appearance of knots, are also possible. To place the wire according to these particular windings, winding machines are provided which are capable of describing the shape chosen and of discharging the wire onto the support progressively during the chosen path.
Les machines proposées jusqu'à présent sont principalement constituées d'engrenages et de bras rotatifs. De telles machines sont coûteuses, peu précises en ce qui concerne le trajet de dépôt du fil, et ne permettent que difficilement de modifier la forme de la bobine à former. Ce dernier défaut est particulièrement gênant du fait que la forme géométrique de la bobine doit être particulièrement précise et serait avantageusement optimisée par des retouches successives de la forme du trajet du fil au fur et à mesure des séries d'emballages réalisées par l'automatisme.The machines offered so far mainly consist of gears and rotating arms. Such machines are costly, imprecise with regard to the path for depositing the wire, and make it difficult to modify the shape of the coil to be formed. This last defect is particularly troublesome because the geometric shape of the spool must be particularly precise and would be advantageously optimized by successive retouching of the shape of the path of the wire as and when the series of packages produced by the automation.
La présente invention se propose de répondre à ces inconvénients. Pour cela, on propose un dispositif de bobinage d'un fil de suture sur un support d'emballage de ce fil, caractérisé par le fait qu'il comporte un guide fil placé sur un équipage mobile en translation selon une première direction sur un ensemble-support et associé à un premier moyen moteur pour être déplacé sélectivement selon cette direction, ledit ensemble-support étant lui même mobile en translation selon une seconde direction transversale à la première et associé à un second moyen moteur pour être déplacé sélectivement selon cette direction.The present invention proposes to respond to these drawbacks. For this, a device is proposed for winding a suture thread on a support for packaging this suture, characterized in that it comprises a thread guide placed on an assembly movable in translation in a first direction on an assembly -support and associated with a first drive means to be selectively moved in this direction, said support assembly itself being movable in translation in a second direction transverse to the first and associated with a second drive means to be selectively moved in this direction.
D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre, faite en rapport aux figures annexées sur lesquelles :Other characteristics, objects and advantages of the present invention will appear on reading the detailed description which follows, given in relation to the appended figures in which:
- la figure 1 représente en vue de dessus un aménagement d'entraînement du fil conforme à une première variante de l'invention ;- Figure 1 shows a top view of a wire drive arrangement according to a first variant of the invention;
- la figure 2 représente le même aménagement en vue de côté ;- Figure 2 shows the same arrangement in side view;
- la figure 3 représente en vue de dessous un aménagement d'entraînement de fil conforme à une seconde variante de l'invention.- Figure 3 shows a bottom view of a wire drive arrangement according to a second variant of the invention.
Le dispositif représenté à la figure 1 se compose de quatre éléments principaux : un rail fixe 10, un rail mobile 20, un moteur linéaire 30 monté à déplacement le long du rail 10, et un moteur linéaire 40 d'entraînement longitudinal du rail 20. Les rails 10 et 20 sont disposés, quelque soit l'état du présent dispositif, perpendiculairement l'un à l'autre. Pour cela, le moteur 30 est un moteur linéaire monté sur le rail 10 sans liberté de rotation, et le moteur 40, solidaire du moteur 30, comporte un canal à travers lequel s'étend le rail 20 avec seulement une liberté de translation longitudinale. Ainsi, le rail 20 est fixe en rotation par rapport au rail 10, par l'action de maintien des deux moteurs 30 et 40 solidaires l'un à l'autre. Le moteur 30 est un moteur linéaire à déplacement longitudinal sur le rail fixe 10, qui entraîne donc avec lui le moteur 40 et le rail 20.The device represented in FIG. 1 is made up of four main elements: a fixed rail 10, a movable rail 20, a linear motor 30 mounted to move along the rail 10, and a linear motor 40 for longitudinal drive of the rail 20. The rails 10 and 20 are arranged, whatever the state of the present device, perpendicular to one another. For this, the motor 30 is a linear motor mounted on the rail 10 without freedom of rotation, and the motor 40, integral with the motor 30, comprises a channel through which the rail 20 extends with only a freedom of longitudinal translation. Thus, the rail 20 is fixed in rotation relative to the rail 10, by the action of holding the two motors 30 and 40 integral with one another. The motor 30 is a linear motor with longitudinal displacement on the fixed rail 10, which therefore drives with it the motor 40 and the rail 20.
Le rail 20 forme donc un équipage, mobile en translation longitudinale sur un ensemble-support formé par les moteurs 30, 40, cet ensemble-support étant lui-même mobile en translation selon la direction du rail fixe 10.The rail 20 therefore forms an assembly, movable in longitudinal translation on a support assembly formed by the motors 30, 40, this support assembly itself being movable in translation in the direction of the fixed rail 10.
Le rail 20 est donc mobile à la fois selon sa direction principale et selon une direction qui lui est transversale.The rail 20 is therefore movable both in its main direction and in a direction which is transverse to it.
Le rail 10 est formé d'une glissière de guidage 105 et d'un barreau aimanté 102 parallèles l'un à l'autre. Ces deux éléments sont fixés par leurs extrémités sur un support 101 fixe, par deux pièces de liaison 103.The rail 10 is formed by a guide slide 105 and a magnetic bar 102 parallel to each other. These two elements are fixed by their ends to a fixed support 101, by two connecting pieces 103.
Le barreau 102 parcourt le rail dans sa partie supérieure, et traverse un canal central du moteur 30.The bar 102 traverses the rail in its upper part, and crosses a central channel of the motor 30.
Le barreau aimanté 102 et le moteur 30 forment un ensemble d'entraînement linéaire à interaction magnétique de type connu. Le barreau 102 est formé d'une succession d'éléments aimantés à polarité alternativement positive et négative, le moteur 30 étant, lui, apte à générer dans son canal central des champs magnétiques alternatifs. Ces champs alternatifs interagissent avec le barreau 102 pour produire une progression du moteur 30, selon un incrément de polarité à chaque variation de champs. Le moteur 30 et le rail 10 présentent donc une translation relative commandée par incréments.The magnetic bar 102 and the motor 30 form a linear drive assembly with magnetic interaction of known type. The bar 102 is formed from a succession of magnetized elements with alternately positive and negative polarity, the motor 30 being itself capable of generating alternating magnetic fields in its central channel. These alternating fields interact with the bar 102 to produce a progression of the motor 30, according to an increment of polarity with each variation of fields. The motor 30 and the rail 10 therefore have a relative translation controlled by increments.
Le moteur 40 et le rail 20 présentent la même structure, le rail 20 comportant un barreau 112 identique au barreau 102, et une glissière 115 rendus solidaires par des têtes de liaison 113, et le barreau 112 traversant le moteur 40 par un canal central de ce dernier.The motor 40 and the rail 20 have the same structure, the rail 20 comprising a bar 112 identical to the bar 102, and a slide 115 made integral by connection heads 113, and the bar 112 passing through the motor 40 by a central channel of this last.
Pour chacun de ces deux aménagements, le barreau aimanté n'est pas en contact avec les parois intérieures du canal du moteur correspondant. Ainsi, ces moteurs 30 et 40 ne présentent aucun frottement, aucun engrenage, ni aucune pièce mécanique interne en mouvement. Ces moteurs ne présentent donc ni jeu, ni usure. Ils sont silencieux, souples, propres, fiables, rapides et précis. Sur une des deux têtes de liaison 113 du rail mobile 20 est rapportée une pince de bobinage 80 servant à canaliser et à guider le fil pendant le bobinage, tout en l'autorisant à coulisser à travers elle, de sorte que le rail 20 guide le trajet de dépôt du fil sur un support placé au dessous de lui. Les moteurs 30 et 40 sont reliés à un dispositif d'alimentation et de commande 70 apte à piloter le moteur 30 et le rail 20 selon des déplacements choisis.For each of these two arrangements, the magnetic bar is not in contact with the interior walls of the channel of the corresponding motor. Thus, these motors 30 and 40 have no friction, no gearing, or any internal mechanical part in movement. These motors therefore have neither play nor wear. They are silent, flexible, clean, reliable, fast and precise. On one of the two connecting heads 113 of the movable rail 20 is attached a winding clamp 80 used to channel and guide the wire during winding, while allowing it to slide through it, so that the rail 20 guides the path for depositing the wire on a support placed below it. The motors 30 and 40 are connected to a supply and control device 70 capable of controlling the motor 30 and the rail 20 according to selected displacements.
Le dispositif 70 est ici un microprocesseur à servo-contrôle analogique dont les signaux de commande transmis aux moteurs 30 et 40 sont facilement mémorisés et modifiables et peuvent être saisis à partir d'une définition mathématique de la géométrie de la bobine à réaliser. Chaque moteur est relié à un rack de contrôle ou bloc de puissance, lui-même sous contrôle du microprocesseur.The device 70 is here a microprocessor with analog servo-control whose control signals transmitted to the motors 30 and 40 are easily memorized and modifiable and can be entered on the basis of a mathematical definition of the geometry of the coil to be produced. Each motor is connected to a control rack or power block, itself under microprocessor control.
Par la programmation de ce microprocesseur 70, on commande donc les positions du moteur 30 et du rail 20 selon une cinématique coordonnée.By programming this microprocessor 70, the positions of the motor 30 and of the rail 20 are therefore controlled according to a coordinated kinematics.
Les rails 10 et 20 étant transversaux, l'équipage formé par le rail 20 peut donc décrire tout type de mouvement dans un plan horizontal.The rails 10 and 20 being transverse, the crew formed by the rail 20 can therefore describe any type of movement in a horizontal plane.
A chaque instant, on choisit la position du rail 20 selon sa direction principale en transmettant au moteur 40 le signal correspondant à cette position, et on choisit la position du rail 20 selon la direction du rail 10 en choisissant la position du moteur 30.At each instant, the position of the rail 20 is chosen according to its main direction by transmitting to the motor 40 the signal corresponding to this position, and the position of the rail 20 is chosen according to the direction of the rail 10 by choosing the position of the motor 30.
On imprime notamment à la pince 80 un mouvement en forme de 8.In particular, the gripper 80 prints an 8-shaped movement.
Le dispositif 70 est également muni d'un moyen d'affichage pour permettre de programmer et suivre le tracé du mouvement de la pince 80. On peut ainsi également identifier un éventuel écart de positionnement et permettre des ajustements nécessaires pour obtenir l'écart minimal et ainsi la meilleure performance.The device 70 is also provided with a display means to allow programming and following the path of the movement of the clamp 80. It is thus also possible to identify a possible positioning deviation and allow the necessary adjustments to obtain the minimum deviation and thus the best performance.
Bien entendu, les rails 10 et 20 ne sont pas nécessairement disposés perpendiculairement, il suffit qu'ils soient transversaux l'un à l'autre. Dans un mode de réalisation particulier de l'invention, la pince 80 est commandée pneumatiquement par le microprocesseur 70, de sorte qu'elle est apte à venir saisir le fil et à lui faire parcourir un 8 en le laissant coulisser entre ses deux doigts.Of course, the rails 10 and 20 are not necessarily arranged perpendicularly, it suffices that they are transverse to each other. In a particular embodiment of the invention, the clamp 80 is pneumatically controlled by the microprocessor 70, so that it is able to come and grab the wire and make it run an 8 while letting it slide between its two fingers.
Selon une disposition avantageuse de l'invention, le dispositif d'entraînement du fil qui vient d'être décrit est disposé directement en aval d'un dispositif adapté pour placer automatiquement une aiguille sur un support d'emballage, cette aiguille ayant été préalablement fixée sur le fil de suture.According to an advantageous arrangement of the invention, the thread drive device which has just been described is arranged directly downstream of a device suitable for automatically placing a needle on a packaging support, this needle having been previously fixed on the suture.
Le support d'emballage équipé de l'aiguille est amené automatiquement sous une position initiale de la pince 80 de sorte que la pince vient serrer légèrement le fil à sa jonction avec l'aiguille fixée sur le support.The packaging support equipped with the needle is automatically brought into an initial position of the clamp 80 so that the clamp comes to slightly tighten the wire at its junction with the needle fixed on the support.
Selon une disposition avantageuse, la machine présente également des doigts traversant automatiquement le support et permettant l'enroulement des deux boucles opposées du 8 en appui autour de ces doigts. Ainsi, une fois le fil saisi, la pince 80 décrit la forme choisie, ici celle d'un 8, en entourant chacun des doigts d'appui traversant le support. Au cours du bobinage, le fil de suture glisse entre les deux doigts de la pince avec une force de frottement choisie pour donner au fil une légère tension au cours du bobinage. Lorsque la pince a parcouru l'ensemble du fil de suture, celle-ci retourne dans une position initiale, puis un battant du flanc cartonné est replié sur la bobine de fil déposée pour maintenir celle-ci en position, puis les doigts traversants s'effacent du support qui peut alors être replié dans sa disposition finale.According to an advantageous arrangement, the machine also has fingers automatically passing through the support and allowing the winding of the two opposite loops of the 8 bearing around these fingers. Thus, once the wire has been gripped, the clamp 80 describes the chosen shape, here that of an 8, by surrounding each of the support fingers passing through the support. During the winding, the suture slides between the two fingers of the pliers with a friction force chosen to give the thread a slight tension during the winding. When the clamp has traversed the entire suture, it returns to an initial position, then a flap of the cardboard side is folded over the spool of thread deposited to maintain it in position, then the through fingers erase from the support which can then be folded back into its final arrangement.
Dans un second mode de réalisation de l'invention représenté sur la figure 2, deux moteurs 30 et 40 entraînent chacun une courroie en boucle respective 34, 44 circulant à chaque fois autour de deux poulies, chaque paire de poulies définissant une direction de déplacement.In a second embodiment of the invention shown in FIG. 2, two motors 30 and 40 each drive a respective loop belt 34, 44 each time circulating around two pulleys, each pair of pulleys defining a direction of movement.
Ces deux courroies en boucle s'étendent ici selon des directions perpendiculaires l'une à l'autre. Une première courroie 44 porte un équipage 42 muni d'un guide-fil et est montée sur un ensemble support 20 fixé sur la seconde courroie 34. Ainsi, l'équipage 42 est entraîné sur l'ensemble support 20 selon une première direction par le moteur 40, et l'ensemble-support 20 est lui-même entraîné selon une seconde direction transversale à la première par la courroie 34 et le moteur 30.These two loop belts extend here in directions perpendicular to each other. A first belt 44 carries an equipment 42 provided with a thread guide and is mounted on a support assembly 20 fixed on the second belt 34. Thus, the equipment 42 is driven on the support assembly 20 in a first direction by the motor 40, and the support assembly 20 is itself driven in a second direction transverse to the first by the belt 34 and the motor 30.
Les deux moteurs 30 et 40 sont là encore commandés par un processeur 70 de sorte que le mouvement de l'équipage 42 est facilement et précisément mis au point.The two motors 30 and 40 are again controlled by a processor 70 so that the movement of the crew 42 is easily and precisely developed.
Bien entendu, l'invention ne se limite pas à un bobinage en forme de 8, mais permet au contraire une modification facile du mouvement de bobinage produit par l'ensemble d'entraînement. Il suffit pour cela de programmer le microprocesseur 70 selon une autre forme choisie.Of course, the invention is not limited to an 8-shaped winding, but on the contrary allows an easy modification of the winding movement produced by the drive assembly. It suffices to program the microprocessor 70 according to another chosen form.
Le dispositif selon l'invention est donc particulièrement avantageux, notamment lors de changements de séries, par exemple lors de changements de géométrie de bobinage, de longueur de fil ou de vitesse de production. The device according to the invention is therefore particularly advantageous, in particular when changing series, for example when changing winding geometry, length of wire or production speed.
