Description

Dispositif de solidarisation par encliquetage d'un outil sur un manche.Securing device by snap-fastening a tool on a handle.
La présente invention a pour objet un dispositif de solidarisation par encliquetage d'un outil sur un manche destiné à être utilisé, non exclusivement, dans domaine de la chirurgie. En chirurgie, la pose d'un implant prothétique par exemple, nécessite un ensemble d'instruments appelé aπcillaire qui comporte notamment des outils a main.The present invention relates to a device for securing by snapping a tool on a handle intended to be used, not exclusively, in the field of surgery. In surgery, the placement of a prosthetic implant, for example, requires a set of instruments called aπcillaire which notably includes hand tools.
Généralement, chacun de ces outils est muni d'un manche ce qui présente des inconvénients de volume, de poids et de coût de fabπcation.Generally, each of these tools is provided with a handle, which has drawbacks in terms of volume, weight and manufacturing cost.
Pour pallier ces inconvénients on a proposé des outils adaptables sur un manche unique, la solidarisation étant réalisée soit par vissage, soit, le plus fréquemment, par serrage au moyen d'une bague filetée vissée sur un embout élastique transversalement.To overcome these drawbacks, tools have been proposed which can be adapted to a single handle, the connection being made either by screwing, or, most frequently, by tightening by means of a threaded ring screwed onto an elastic end piece transversely.
Ces dispositifs présentent toutefois des inconvénients de rapidité de mise en place et de fiabilitéHowever, these devices have drawbacks in terms of speed of installation and reliability.
En effet, le changement d'outil n'est pas immédiat puisqu'il nécessite des opérations de dévissage et de vissage.Indeed, the tool change is not immediate since it requires unscrewing and screwing operations.
D'autre part, le blocage n'est obtenu qu'à un certain couple de serrage, et si celui-ci n'est pas atteint la solidarisation n'est pas optimale.On the other hand, the blocking is only obtained at a certain tightening torque, and if this is not reached the connection is not optimal.
De plus, certains outils servent à l'impaction, il y a donc nécessité de frapper, parfois très fort, sur l'arrière du manche, avec un risque de desol idarisation de 1 'outi 1 du manche.In addition, some tools are used for impaction, so there is a need to strike, sometimes very hard, on the back of the handle, with a risk of desolation idarization of the tool 1 of the handle.
La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de manche auquel un outil peut être solidarise instantanément et fermement par encliquetage, sans risque d'une désol idarisation inopinée.The object of the present invention is to remedy these drawbacks by proposing a handle device to which a tool can be secured instantaneously and firmly by snap-fastening, without the risk of unexpected loss of comfort.
Le dispositif objet de la présente invention se caractérise essentiellement en ce que d'une Dart il comporte un manche renfermant axialement une tige dont une extrémité fait saillie de l'une des extrémités dudit manche, et sur laquelle est enfilée une bague apte a coulisser entre l'extrémité dudit manche et une douille solidaire de l 'extrémité de ladite tige et contre laquelle ladite bague est rappelée par un ressort, ladite douille comportant frontalement au moins une fente radiale communicant latéralement dans le prolongement de son fond avec une échancrure créée par un perçage radial, ledit fond étant percé, parallèlement à l'axe de ladite tige en regard de ladite fente, d'un canal dans lequel passe une barre solidaire de la bague mobile et qui prend place dans ladite fente lorsque ladite bague est repoussée par le ressort; et en ce que d'autre part l'extrémité de solidarisation de l'outil comporte un embout cylindrique destiné à être introduit axialement dans la douille, et duquel fait saillie radialement un ergot destiné à prendre place dans ladite échancrure en passant préalablement par ladite fente en repoussant ladite barre.The device which is the subject of the present invention is essentially characterized in that, from a Dart, it comprises a handle axially enclosing a rod, one end of which projects from one of the ends of said handle, and on which is threaded a ring capable of sliding between the end of said handle and a socket integral with the end of said rod and against which said ring is biased by a spring, said socket frontally comprising at least one radial slot communicating laterally in the extension from its bottom with a notch created by a radial bore, said bottom being pierced, parallel to the axis of said rod opposite said slot, with a channel through which passes a bar secured to the movable ring and which takes place in said slot when said ring is pushed back by the spring; and in that, on the other hand, the attachment end of the tool comprises a cylindrical endpiece intended to be introduced axially into the sleeve, and from which protrudes radially a lug intended to take place in said notch by previously passing through said slot by pushing said bar.
Selon une caractéristique additionnelle du dispositif selon l'invention, la tige traverse axialement le manche et est solidarisé en rotation avec le manche.According to an additional characteristic of the device according to the invention, the rod passes axially through the handle and is secured in rotation with the handle.
Selon une autre caractéristique additionnelle du dispositif selon l'invention la tige est tubulaire et débouche à l'extrémité arrière du manche.According to another additional characteristic of the device according to the invention, the rod is tubular and opens out at the rear end of the handle.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. Dans le dessin annexé :The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof. In the attached drawing:

Si on se réfère à la figure 1 on peut voir qu'un dispositif selon l'invention comprend un manche 1 comportant une partie cylindrique 10 de préhension et a son extrémité un ensemble 11 permettant 1 'encl iquetage de l'extrémité 20
Figure imgf000005_0001
If we refer to Figure 1 we can see that a device according to the invention comprises a handle 1 having a cylindrical portion 10 for gripping and at its end an assembly 11 allowing one snap the end 20
Figure imgf000005_0001
Si on se réfère également à la figure 2 on peut voir que l'ensemble 11 comporte un tube 3 introduit axialement dans le manche 1 , et dont l'extrémité libre s'élargie en une douille 30, et sur lequel peut coulisser une bague 4 maintenue en butée contre la douille 30 sous l'action d'un ressort hélicoïdal 40 enfilé sur le tube 3 et prenant appui contre le manche 1.If we also refer to Figure 2 we can see that the assembly 11 comprises a tube 3 inserted axially in the handle 1, and whose free end widens into a sleeve 30, and on which can slide a ring 4 held in abutment against the sleeve 30 under the action of a helical spring 40 threaded on the tube 3 and bearing against the handle 1.
Le canal axial 31 du tube 3 est prolonge de deux alésages cylindriques successifs 32 et 33 de diamètres croissants pratiqués dans la douille 30.The axial channel 31 of the tube 3 is extended by two successive cylindrical bores 32 and 33 of increasing diameters made in the bush 30.
La face frontale 34 de la douille 30 comporte une fente diamétrale 35 dont la partie inférieure est évidée latéralement pour former, dans le prolongement du fond 36 de la fente 35 pour chacune des parties de part et d'autre de l'alésage 33, une échancrure 37, dont une seule est visible sur la figure 2, et obtenue en pratiquant un perçage di amétral .The front face 34 of the sleeve 30 has a diametrical slot 35 whose lower part is hollowed out laterally to form, in the extension of the bottom 36 of the slot 35 for each of the parts on either side of the bore 33, a notch 37, only one of which is visible in FIG. 2, and obtained by practicing di ametral drilling.
Le fond 36 est percé, parallèlement a l'axe du tube 3 et en regard de la fente 35, de deux canaux 38, chacun de part et d'autre de l 'alésage 33, dans chacun desquels est enfilée une barre 41 solidaire de la bague 4, et sous l'action du ressort 40 les parties extrêmes libres 42 des barres 41 prennent position dans la fente 35.The bottom 36 is pierced, parallel to the axis of the tube 3 and opposite the slot 35, with two channels 38, each on either side of the bore 33, in each of which is threaded a bar 41 secured to the ring 4, and under the action of the spring 40 the free end portions 42 of the bars 41 take up position in the slot 35.
L'extrémité 20 de l'outil 2 comprend un embout cylindrique 21 accolé à un embout cylindrique 22, dont les dimensions permettent leur introduction sans jeu dans les alésages, respectivement 32 et 33.The end 20 of the tool 2 comprises a cylindrical end piece 21 attached to a cylindrical end piece 22, the dimensions of which allow their introduction without play in the bores, respectively 32 and 33.
L'embout cylindrique 33 comporte deux ergots 23 saillant diamétralement, de dimensions permettant leur passage par la fente 35 et leur positionnement dans les echancrures 37.The cylindrical end piece 33 has two lugs 23 projecting diametrically, of dimensions allowing their passage through the slot 35 and their positioning in the notches 37.
Si on se réfère maintenant a la figure 3 on peut voir que lors de l'introduction de l'extrémité 20 de l'outil 2 dans la douille 30, les ergote 23 repoussent les barres 41 en comprimant le ressort 40. Si on se réfère aux figures 4 et 5 on peut voir qu'en imprimant une légère rotation axiale à l'outil 2, les ergots 23 prennent place dans les echancrures 37, ce qui permet, sous l'action du ressort 40, l 'extraction des barres 41 dont les parties extrêmes 42 bloquent les ergots 23 dans les echancrures 37.If we now refer to Figure 3 we can see that during the introduction of the end 20 of the tool 2 in the sleeve 30, the pins 23 push the bars 41 by compressing the spring 40. If we refer Figures 4 and 5 we can see that by printing a slight axial rotation with the tool 2, the pins 23 take place in the notches 37, which allows, under the action of the spring 40, the extraction of the bars 41 whose end parts 42 block the pins 23 in the notches 37.
Il est à noter que les extrémités des barres 41 peuvent comporter, du côte des echancrures 37, un léger biseau pour permettre, d'une part un engagement automatique des ergots 23 dans les echancrures 37 lors de l 'introduction de l 'extrémité, 20 de l'outil , et d'autre part une remontée plus aisée des barres 41.It should be noted that the ends of the bars 41 may comprise, on the side of the notches 37, a slight bevel to allow, on the one hand, an automatic engagement of the pins 23 in the notches 37 when the end is introduced, 20 of the tool, and on the other hand an easier raising of the bars 41.
Pour désengager l'outil du manche 1 il suffit de tirer sur la bague et de tirer sur l 'outil 2.To disengage the tool from the handle 1, simply pull on the ring and pull on the tool 2.
Le tube 3 traverse axialement toute la partie cylindrique 10 de préhension et l 'outil 2 est creux, en sorte que cela permet avantageusement d'y introduire par l'arrière un second outil susceptible par exemple de maintenir une pièce en extrémité de l'outil 2.The tube 3 passes axially through the entire cylindrical gripping part 10 and the tool 2 is hollow, so that it advantageously allows a second tool to be inserted therein, capable for example of holding a part at the end of the tool. 2.
Sur la figure 4 on peut voir que l'extrémité arrière 39 du tube 3 comporte longitudinalement une fente 390 destinée à recevoir une goupille 50, qui ne traverse pas le canal axial 31 , permettant de bloquer en rotation le tube 3, la goupille 50 étant solidaire d'une bague 5 solidarisée en rotation au manche 1. Le tube 3 est solidarisé au manche 1 au moyen d'un écrou 12 vissé sur l'extrémité arrière 39 de tube 3 qui comporte un filetage 391 , et prenant appui sur 1 'épaulement 13 d'un évidement 14 pratiqué dans le manche 1, le tube 3 étant bloque dans sa partie avant par un épaulement 15 visible sur les figure 2 et 3. Ce mode de fabrication permet un démontage aise de l'ensemble en vue de la stérilisation de toutes les pièces qui le constituent.In FIG. 4, it can be seen that the rear end 39 of the tube 3 longitudinally has a slot 390 intended to receive a pin 50, which does not pass through the axial channel 31, making it possible to block the tube 3 in rotation, the pin 50 being secured to a ring 5 secured in rotation to the handle 1. The tube 3 is secured to the handle 1 by means of a nut 12 screwed onto the rear end 39 of the tube 3 which comprises a thread 391, and bearing on the shoulder 13 of a recess 14 formed in the handle 1, the tube 3 being blocked in its front part by a shoulder 15 visible in FIGS. 2 and 3. This method of manufacture allows easy disassembly of the assembly for the sterilization of all the parts that constitute it.
Si on se réfère maintenant a la figure 6 on peut voir que dans une variante, l'extrémité arrière 39 du tube 3 comporte une partie 392 de section carrée sur laquelle est enfilée une bague 6, de forme intérieure complémentaire, prenant place dans un logement 16 du manche 1 et solidarisée en rotation à ce dernier par l'intermédiaire d'au moins un ergot 60 engagé dans une gorge longitudinale 17. La partie 392 est prolongée d'une zone filetéeReferring now to Figure 6 we can see that in a variant, the rear end 39 of the tube 3 has a portion 392 of square section on which is threaded a ring 6, of complementary interior shape, taking place in a housing 16 of the handle 1 and secured in rotation to the latter by means of at least one lug 60 engaged in a longitudinal groove 17. The part 392 is extended by a threaded zone
393 sur laquelle est vissé l'alésage taraude 70 d'une tête 7 destinée à être frappée lors d'une impaction, et qui prend appui sur le manche 1 et maintient la bague 6 dans son logement 16. La. tête 7 comporte un trou 71 en regard du canal axial 31 du tube 3 afin de permettre l'introduction d'un second outi 1.393 on which is screwed the tap hole 70 of a head 7 intended to be struck during an impact, and which bears on the handle 1 and maintains the ring 6 in its housing 16. The head 7 has a hole 71 opposite the axial channel 31 of the tube 3 in order to allow the introduction of a second tool 1.
La tête 7 comporte également, sur sa face arrière 72, une empreinte creuse 73 permettant son manoeuvrement, cette empreinte creuse 73 peut avantageusement correspondre à l'empreinte mâle d'un outil 2 couramment utilise.The head 7 also includes, on its rear face 72, a hollow imprint 73 allowing it to be maneuvered, this hollow imprint 73 may advantageously correspond to the male imprint of a tool 2 commonly used.
Il va de soi que la présente invention ne saurait être limitée à la description qui précède de quelques-uns de ses modes de réalisation, susceptibles de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention cannot be limited to the foregoing description of some of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
