Description
Porte-outil universel notamment Pour la mise en place d'organes de fixation dans des supports difficilement accessibles.Universal tool holder in particular For the installation of fasteners in hard to reach supports.
La présente invention concerne un porte-outil universel notamment pour la mise en place d'organes de fixation dans des supports difficilement accessibles tels que des os lors d'interventions chirurgicales.The present invention relates to a universal tool holder in particular for the installation of fastening members in difficultly accessible supports such as bones during surgical operations.
Certaines interventions chirurgicales, en particulier dans le cas de fractures osseuses, nécessitent l'utilisation d'organes de fixation tels que des vis pour permettre la réparation par exemple par l'adjonction de cales ou par tout autre moyen approprié. Or, on constate que dans un grand nombre d'opérations de ce type les os sont difficilement accessibles.Certain surgical procedures, in particular in the case of bone fractures, require the use of fixing members such as screws to allow repair, for example by adding wedges or by any other appropriate means. However, it is found that in a large number of operations of this type the bones are difficult to access.
En raison de l'inaccessibilité du site, on observe une imprécision dans la localisation de l'organe de fixation, un risque de lésion des éléments vasculo-nerveux adjacents et parfois une perte de certains éléments de fixation, tels que des rondelles, dans l'organisme.Due to the inaccessibility of the site, there is an inaccuracy in the location of the fixing organ, a risk of damage to the adjacent vascular-nervous elements and sometimes a loss of certain fixing elements, such as washers, in the 'organization.
Le but de la présente invention est donc de proposer un porteoutil qui pallie les inconvénients précités en permettant à son utilisateur de travailler à distance tout en positionnant de manière très précise les organes de fixation.The object of the present invention is therefore to propose a tool holder which overcomes the aforementioned drawbacks by allowing its user to work remotely while very precisely positioning the fixing members.
L'invention concerne à cet effet un porte-outil universel, notamment pour la mise en place d'organes de fixation dans des supports difficilement accessibles, en particulier dans des os lors d'interventions chirurgicales, caractérisé en ce qu'il se présente sous forme d'un corps tubulaire comportant un alésage axial traversant et muni à une de ses extrémités d'une pluralité de doigts radiaux élastiquement déformables qui s'écartent radialement vers l'extérieur de l'axe longitudinal du porte-outil, lorsqu'on exerce au moyen d'un outil approprié une action de poussée sur un organe de fixation introduit par l'extrémité opposée dans le porte-outil de manière à désengager ledit organe de fixation du porte-outil.To this end, the invention relates to a universal tool holder, in particular for the installation of fastening members in hardly accessible supports, in particular in bones during surgical operations, characterized in that it is presented under form of a tubular body having an axial through bore and provided at one of its ends with a plurality of elastically deformable radial fingers which deviate radially outward from the longitudinal axis of the tool holder, when exercising by means of a suitable tool, a pushing action on a fixing member introduced by the opposite end in the tool holder so as to disengage said fixing member from the tool holder.
Selon une forme de réalisation préférée de l'invention, les doigts radiaux ménagent un logement de réception d'un organe de fixation supplémentaire tel qu'une rondelle introduit à force dans ledit logement, ledit organe supplémentaire étant susceptible d'être désaccouplé desdits doigts lors de l'avancement de l'organe de fixation et de l'outil qui écartent les doigts du porte-outil.According to a preferred embodiment of the invention, the radial fingers provide a housing for receiving an additional fixing member such as a washer forced into said housing, said additional member being capable of being uncoupled from said fingers during the advancement of the fixing member and the tool which spread the fingers of the tool holder.
L'invention concerne également un procédé de mise en place d'organes de fixation sur un support au moyen d'un porte-outil conforme à la revendication 1, caractérisé en ce qu'on positionne par enfoncement une extrémité du porte-outil sur son support, en ce qu'on introduit par l'autre extrémité du porte-outil un organe de fixation, en ce qu'on exerce sur cet organe une action de poussée au moyen d'un outil introduit par la même extrémité, l'avancement de l'organe et de l'outil dans le porte-outil entraînant un écartement radial externe des doigts.The invention also relates to a method of fitting fastening members to a support by means of a tool holder according to claim 1, characterized in that one end of the tool holder is positioned on its support, in that one introduces by the other end of the tool holder a fixing member, in that one exerts on this member a thrust action by means of a tool introduced by the same end, the advancement of the member and the tool in the tool holder causing an external radial separation of the fingers.

Le porte-outil 1, objet de l'invention, représenté aux figures 1 et 5, se présente sous forme d'un élément tubulaire muni d'un alésage axial traversant organisé autour d'un axe longitudinal D. Ce porte-outil comporte à l'une de ses extrémités une pluralité de doigts radiaux 2. Dans les exemples représentés, les doigts sont au nombre de quatre. Ces doigts, séparés les uns des autres par une fente 3, sont élastiquement déformables entre deux positions extrêmes, l'une voisine de l'axe longitudinal D du porte-outil, l'autre écartée de l'axe longitudinal D du porte-outil. L'écartement radial externe des doigts 2 peut être amélioré en favorisant le pivotement radial des doigts au moyen d'une gorge disposée à la base du doigt dans la zone de liaison du doigt avec le corps du porte-outil. Cette possibilité n'est pas représentée dans les dessins. Au moins deux des doigts radiaux 2 comportent sur leurs parois intérieures un renflement 10. Ce renflement 10, qui peut affecter un grand nombre de formes, comporte une face 15 d'appui de l'organe de fixation, comme le montre la première vue de la figure 5, puis de l'outil introduits dans le porte-outil par l'extrémité opposée à celle portant les doigts. Les faces d'appui 15 disposées en regard sur au moins deux doigts diamétralement opposés affectent une forme biseautée à allure divergente de l'extrémité du porteoutil équipée de doigts vers l'extrémité servant à l'introduction d'outils. Ainsi, tel que représenté à la figure 5, ce renflement 10 affecte la forme d'une dent de rochet.The tool holder 1, object of the invention, shown in FIGS. 1 and 5, is in the form of a tubular element provided with a through axial bore organized around a longitudinal axis D. This tool holder comprises one of its ends a plurality of radial fingers 2. In the examples shown, there are four fingers. These fingers, separated from each other by a slot 3, are elastically deformable between two extreme positions, one close to the longitudinal axis D of the tool holder, the other spaced from the longitudinal axis D of the tool holder . The external radial spacing of the fingers 2 can be improved by promoting the radial pivoting of the fingers by means of a groove disposed at the base of the finger in the zone of connection of the finger with the body of the tool holder. This possibility is not shown in the drawings. At least two of the radial fingers 2 have on their internal walls a bulge 10. This bulge 10, which can have a large number of shapes, has a bearing face 15 for the fixing member, as shown in the first view of Figure 5, then the tool inserted into the tool holder by the end opposite to that carrying the fingers. The bearing faces 15 arranged facing each other on at least two diametrically opposite fingers have a bevelled shape with a divergent appearance from the end of the tool holder fitted with fingers towards the end used for the introduction of tools. Thus, as shown in Figure 5, this bulge 10 affects the shape of a ratchet tooth.
Grâce à ce renflement 10, l'organe de fixation et l'outil qui sont introduits dans le porte-outil viennent au cours de leur avancement dans le porte-outil en appui sur les faces d'appui 15 du renflement et écartent ces dernières entraînant de ce fait un écartement des doigts radiaux. Dans le cas où l'organe de fixation est une vis 13 telle que représentée à la figure 4, c'est la face d'application sensiblement hémisphérique de la tête de vis 12 qui vient en appui sur la face d'appui 15 du renflement et entraîne un écartement desdits doigts. Une fois la vis désengagée du porte-outil, c'est la partie conique 7 de l'outil 6, en l'occurrence un tournevis, représenté à la figure 3, qui vient en appui sur la face d'appui 15 du renflement 10 du porte-outil de manière à maintenir les doigts écartés pendant toute l'opération de fixation, en l'occurrence de serrage. Cette partie conique 7 du tournevis ménagée sur le manche du tournevis est contigüe de la tête de tournevis 8.Thanks to this bulge 10, the fixing member and the tool which are introduced into the tool holder come during their advancement in the tool holder in abutment on the bearing faces 15 of the bulge and separate the latter causing therefore a spacing of the radial fingers. In the case where the fixing member is a screw 13 as shown in FIG. 4, it is the substantially hemispherical application face of the screw head 12 which comes to bear on the support face 15 of the bulge and causes said fingers to move apart. Once the screw disengaged from the tool holder, it is the conical part 7 of the tool 6, in this case a screwdriver, shown in FIG. 3, which comes to bear on the bearing face 15 of the bulge 10 of the tool holder so as to keep the fingers apart during the entire fixing operation, in this case clamping. This conical part 7 of the screwdriver formed on the handle of the screwdriver is contiguous with the screwdriver head 8.
Dans le cas où l'organe de fixation, tel que représenté à la figure 4, doit être associé à un autre organe tel qu'une rondelle 16, le porte-outil est conforme à la figure 5 Dans ce cas, au moins deux doigts radiaux 2 ménagent à leur extrémité un logement de réception 9 de ladite rondelle. Ce logement 9 est délimité d'une part par un épaulement radial interne 14 disposé à l'extrémité du doigt, d'autre part par une face du renflement 10, en l'occurrence la face distale. De ce fait, lors de l'écartement des doigts radiaux 2, par l'intermédiaire de l'organe de fixation, par exemple la vis 13, la rondelle 16 traversée par le corps de la vis, qui fait saillie à l'extrémité du porte-outil, est désaccouplée du porte-outil comme le montre la troisième vue de la figure 5. Par la suite, la poussée continue sur la vis 13 exercée par l'outil 6 entraîne le désengagement total de la vis 13.In the case where the fixing member, as shown in Figure 4, must be associated with another member such as a washer 16, the tool holder conforms to Figure 5 In this case, at least two fingers 2 radials provide at their end a housing 9 for receiving said washer. This housing 9 is delimited on the one hand by an internal radial shoulder 14 disposed at the end of the finger, on the other hand by a face of the bulge 10, in this case the distal face. Therefore, during the spacing of the radial fingers 2, through the fixing member, for example the screw 13, the washer 16 traversed by the body of the screw, which projects at the end of the tool holder, is uncoupled from the tool holder as shown in the third view of FIG. 5. Thereafter, the continuous thrust on the screw 13 exerted by the tool 6 causes the total disengagement of the screw 13.
La rondelle 16 est disposée à force dans le logement 9 de réception du porte-outil. Il est ainsi possible, lors de cette opération de montage, de supprimer tout contact manuel avec la rondelle. Il suffit de choisir une rondelle présentant une face d'application plane de type plateau et une face d'appui avec la tête de l'organe de fixation par exemple la vis 13 cylindro-conique. On dispose ces rondelles sur des supports affectant la forme de ziggourats à plates-formes circulaires, la rondelle étant maintenue à la surface de l'avant dernière plate forme. on vient coiffer ce support avec le porte-outil 1 maintenu verticalement, son extrémité munie de doigts disposée en regard du support de rondelle. En exerçant une force verticale, on obtient l'introduction à force de la rondelle dans le logement 9 du porte-outil. On notera que, dans la figure 5, ce logement est constitué par un espace annulaire.The washer 16 is forced into the housing 9 for receiving the tool holder. It is thus possible, during this assembly operation, to eliminate any manual contact with the washer. It suffices to choose a washer having a flat application face of the tray type and a bearing face with the head of the fixing member, for example the cylindrical-conical screw 13. These washers are placed on supports affecting the shape of ziggurats with circular platforms, the washer being held on the surface of the penultimate platform. we just cap this support with the tool holder 1 held vertically, its end provided with fingers disposed opposite the washer support. By exerting a vertical force, one obtains the force introduction of the washer into the housing 9 of the tool holder. Note that, in Figure 5, this housing is constituted by an annular space.
Le porte-outil comporte en outre à son extrémité munie de doigts des éléments saillants, tels que des picots 4, représentés à la figure 1, ces picots permettant un positionnement par appui du porte-outil sur son support.The tool holder further comprises at its end provided with fingers projecting elements, such as pins 4, shown in Figure 1, these pins allowing positioning by pressing the tool holder on its support.
Il est également possible d'utiliser d'autres outils en vue de la réalisation d'opérations spécifiques sur le support. Ainsi, comme le montre la figure 2, il est envisageable d'utiliser un pointeau 5 qui, une fois que le porte-outil muni ou non d'une rondelle est positionné, vient marquer la place du trou à percer.It is also possible to use other tools for carrying out specific operations on the support. Thus, as shown in Figure 2, it is possible to use a needle 5 which, once the tool holder with or without a washer is positioned, marks the place of the hole to be drilled.
Les organes de fixation peuvent également être quelconques.The fixing members can also be any.
Dans le cas de la figure 4, il est représenté une vis 13 malléolaire à pointe carrée.In the case of Figure 4, there is shown a malleolar screw 13 with square tip.
Pour la mise en oeuvre d'un porte-outil conforme à l'invention, on procède de la manière suivante
Dans le cas où l'organe de fixation doit être associé à une rondelle, on commence par prélever la rondelle de son support, celle-ci venant se loger dans le logement 9 prévu à cet effet.For the implementation of a tool holder according to the invention, the procedure is as follows
In the case where the fixing member must be associated with a washer, one begins by removing the washer from its support, the latter being received in the housing 9 provided for this purpose.
Puis, on positionne le porte-outil sur son support, tel qu'un os, à l'aide des picots 4. Ensuite, on introduit, par l'extrémité opposée du porte-outil, d'abord le pointeau si nécessaire de manière à réaliser un pré-trou, puis, après enlèvement de ce dernier, l'organe de fixation suivi de l'outil. Cet outil entraîne en rotation exerce une action de poussée sur l'organe de fixation qui fait progressivement saillie hors du porte-outil en écartant simultanément les doigts radiaux du dispositif porte-outil de manière à désaccoupler d'abord la rondelle du porte-outil puis l'organe de fixation. Une fois l'organe de fixation muni de sa rondelle extrait du porte-outil, l'action de serrage continue, les doigts radiaux étant maintenus écartés par les faces périphériques du corps de l'outil de serrage qui viennent en appui contre les faces d'appui des renflements des parois internes des doigts. Lorsque l'opération de serrage est terminée, on retire l'outil puis le porte-outil. Pour obtenir un résultat optimal, on alterne les doigts radiaux équipés de picot donc fixes et les doigts radiaux exempts de picots donc mobiles et susceptibles de s'écarter de l'axe longitudinal du porte-outil.Then, the tool holder is positioned on its support, such as a bone, using the pins 4. Then, by means of the opposite end of the tool holder, the needle is first introduced if necessary. to make a pre-hole, then, after removal of the latter, the fixing member followed by the tool. This tool drives in rotation exerts a pushing action on the fixing member which gradually protrudes out of the tool holder while simultaneously spreading the radial fingers of the tool holder device so as to uncouple the washer from the tool holder first and then the fixing member. Once the fixing member provided with its washer extracted from the tool holder, the clamping action continues, the radial fingers being kept apart by the peripheral faces of the body of the clamping tool which come to bear against the faces d 'support of the bulges of the internal walls of the fingers. When the clamping operation is complete, the tool is removed and then the tool holder. To obtain an optimal result, the radial fingers fitted with a pin, therefore fixed, are alternated with the radial fingers free of pins which are therefore mobile and capable of deviating from the longitudinal axis of the tool holder.
Pour faciliter le rangement des organes de fixation et des outils, il est possible de prévoir un réceptacle tel qu'un panier ajouré équipé de supports appropriés.To facilitate the storage of the fasteners and tools, it is possible to provide a receptacle such as a perforated basket equipped with appropriate supports.
Il est également possible de placer le porte-outil en dépression afin d'éliminer tous les déchets se trouvant à l'autre extrémité. Enfin, tout outil peut être utilisé en combinaison avec le porte-outil, objet de 1 invention, pour réaliser l'opération (marquage, vissage, perçage, etc) appropriée.It is also possible to place the tool holder under vacuum in order to eliminate all the waste at the other end. Finally, any tool can be used in combination with the tool holder, object of the invention, to carry out the appropriate operation (marking, screwing, drilling, etc.).
Bien évidemment, l'invention ne se limite pas à la pose de vis lors d'interventions chirurgicales mais englobe toute application dans laquelle le support est difficilement accessible. Obviously, the invention is not limited to the installation of screws during surgical procedures but encompasses any application in which the support is difficult to access.
