Description

Interface de connexion pour instrument chirurgical Connection interface for surgical instrument
Domaine de l'invention Field of the invention
L'invention concerne les dispositifs chirurgicaux formés principalement d'un instrument connecté à un support d'instrument, ce dernier comportant une interface de connexion permettant de connecter, respectivement déconnecter, un instrument au support. The invention relates to surgical devices formed mainly of an instrument connected to an instrument support, the latter comprising a connection interface making it possible to connect, respectively disconnect, an instrument to the support.
État de la technique State of the art
La figure 1 illustre un support d'instrument chirurgical 14 de l'état de la technique. Il est constitué d'une tige 2 comprise entre une interface de connexion 1 et une poignée 3 disposées respectivement vers l'extrémité distale et proximale de la tige 2. Figure 1 illustrates a prior art surgical instrument holder 14. It consists of a rod 2 between a connection interface 1 and a handle 3 arranged respectively towards the distal and proximal end of the rod 2.
La position de la poignée 3 peut être alignée ou perpendiculaire à la tige 2. Dans cet exemple illustré la poignée 3 est disposée perpendiculairement par rapport à la tige 2. The position of the handle 3 can be aligned or perpendicular to the rod 2. In this illustrated example the handle 3 is arranged perpendicular to the rod 2.
Il existe plusieurs types d'interfaces de connexion, p.ex. AO, AO large ou Hudson. There are several types of connection interfaces, eg AO, AO large or Hudson.
L'interface de connexion 1 comprend deux goupilles 4 montées dans des rainures en V 5 (voir figure 2). The connection interface 1 comprises two pins 4 mounted in V-shaped grooves 5 (see figure 2).
Deux rondelles 6 prennent en sandwich un ressort de compression 7 et poussent ainsi les goupilles 4 vers l'axe central de l'interface de connexion 1, ce qui a pour effet de verrouiller un instrument au support d'instrument 14 (voir figure 3). Two washers 6 sandwich a compression spring 7 and thus push the pins 4 towards the central axis of the connection interface 1, which has the effect of locking an instrument to the instrument support 14 (see figure 3) .
Du fait de la forme des rainures en V 5 et de la force exercée par le ressort 7, les goupilles 4 coulissent en direction de l'extrémité distale de la tige 2 et se rapprochent de son axe, ce qui a pour effet de verrouiller un instrument chirurgical (non illustré) au support d'instrument 14.Due to the shape of the V-shaped grooves 5 and the force exerted by the spring 7, the pins 4 slide in the direction of the distal end of the rod 2 and approach its axis, which has the effect of locking a surgical instrument (not shown) to the instrument holder 14.
Pour déverrouiller la connexion, on comprime le ressort 7. Dans ce cas, contrairement à l'opération de verrouillage, aucune force ne s'exerce sur les goupilles 4, de sorte que le mécanisme de déverrouillage a tendance à se gripper, rendant parfois difficile, voire impossible, la déconnexion d'un instrument au support 14. Outre le problème précité, l'interface de connexion 1 est difficilement nettoyable. Le mécanisme verrouillage/déverrouillage est non démontable et tout ce qui s'introduit dans le ressort 7 ne peut être retiré. To unlock the connection, the spring 7 is compressed. In this case, unlike the locking operation, no force is exerted on the pins 4, so that the unlocking mechanism tends to seize up, sometimes making it difficult , if not impossible, the disconnection of an instrument to support 14. Besides the aforementioned problem, the connection interface 1 is difficult to clean. The locking/unlocking mechanism is not removable and anything that gets into the spring 7 cannot be removed.
Il existe donc un besoin d'améliorer les interfaces de connexion des instruments chirurgicaux précités. There is therefore a need to improve the connection interfaces of the aforementioned surgical instruments.
Description générale de l'invention General description of the invention
Le mécanisme de verrouillage/déverrouillage selon la présente invention se différencie notamment des mécanismes de l'état de la technique en ce que les goupilles sont remplacées par un levier pivotant. The locking/unlocking mechanism according to the present invention differs in particular from the mechanisms of the state of the art in that the pins are replaced by a pivoting lever.
De manière plus générale, la présente invention concerne une interface de connexion pour instrument chirurgical telle que décrite dans la revendication principale. More generally, the present invention relates to a connection interface for a surgical instrument as described in the main claim.
De modes de réalisation spécifiques de l'invention sont décrits dans les revendications dépendantes. Specific embodiments of the invention are described in the dependent claims.
L'interface de connexion selon l'invention peut être utilisée avec n'importe quel instrument chirurgical approprié, comme p.ex. un foret, un outil de coupe, un tournevis ou un alésoir. The connection interface according to the invention can be used with any suitable surgical instrument, such as for example a drill, a cutting tool, a screwdriver or a reamer.

L'interface de connexion 1 illustrée sur les figures 4 à 15 comprend un mécanisme de verrouillage/déverrouillage d'instrument 10 qui se compose principalement d'une bague coulissante 11, d'un ressort hélicoïdal 7, de l'extrémité distale de la tige 2 d'un support d'instrument 14, d'un levier pivotant 8 et d'un coulisseau à baïonnette 9. The connection interface 1 illustrated in Figures 4 to 15 comprises an instrument locking/unlocking mechanism 10 which mainly consists of a sliding ring 11, a coil spring 7, the distal end of the stem 2 of an instrument holder 14, a pivoting lever 8 and a bayonet slider 9.
Le levier 8 pivote autour d'un axe 15 qui est fixé vers l'extrémité distale de la tige 2. The lever 8 pivots around an axis 15 which is fixed towards the distal end of the rod 2.
La position de verrouillage du levier 8 (voir les figures 4 à 7) est réalisée par le coulissement distal de la bague 11 ; cette dernière étant entraînée en direction de l'instrument par le ressort 7 (voir figure 4). La bague 11 s'appuie contre une butée annulaire 16 disposée à l'extrémité distale de la tige 2. L'interface de connexion 1 comprend également un coulisseau à baïonnette 9 disposé le long de la tige 2, entre la poignée 3 et la bague 11. En position de verrouillage, le coulisseau 9 est fixe et recouvre le ressort 7. The locking position of the lever 8 (see Figures 4 to 7) is achieved by the distal sliding of the ring 11; the latter being driven in the direction of the instrument by the spring 7 (see FIG. 4). The ring 11 bears against an annular stop 16 arranged at the distal end of the rod 2. The connection interface 1 also comprises a bayonet slider 9 arranged along the rod 2, between the handle 3 and the ring 11. In the locked position, the slider 9 is fixed and covers the spring 7.
Pour le déverrouillage (voir les figures 8 à 11), la bague 11 est déplacée en direction de la poignée 3, ce qui a pour effet de libérer le levier 8 qui peut pivoter légèrement vers le haut, se loger dans une gorge annulaire 13 disposée sur la paroi intérieure de la bague 11 et ainsi libérer l'instrumentFor unlocking (see Figures 8 to 11), the ring 11 is moved in the direction of the handle 3, which has the effect of releasing the lever 8 which can pivot slightly upwards, lodge in an annular groove 13 arranged on the inner wall of the ring 11 and thus release the instrument
10 de l'interface de connexion 1 (voir figures 9 à 11). 10 of the connection interface 1 (see Figures 9 to 11).
Un avantage supplémentaire du mécanisme de verrouillage/déverrouillage selon l'invention réside dans le fait qu'il est totalement démontable et donne accès à tous les endroits pour un nettoyage complet (voir figures 13 et 15). Dans ce cas, le coulisseau 9 est libéré de la tige 2 en le rétractant en direction de la poignée 3. An additional advantage of the locking/unlocking mechanism according to the invention lies in the fact that it can be completely dismantled and gives access to all places for complete cleaning (see FIGS. 13 and 15). In this case, the slider 9 is released from the rod 2 by retracting it in the direction of the handle 3.
11 va de soi que la présente invention ne se limite pas aux exemples illustrés. Le ressort p.ex. n'est pas nécessairement de forme hélicoïdale. De même, le coulisseau ne comporte pas forcément un mécanisme à baïonnette. It goes without saying that the present invention is not limited to the examples illustrated. The spring, for example, is not necessarily of helical shape. Similarly, the slider does not necessarily include a bayonet mechanism.
