Description
La présente invention concerne un instrument pour l'impaction d'un composant acétabulaire pour la reconstruction de l'articulation de la hanche. En général, dans les opérations de reconstruction de l'articulation de la hanche, la technique opératoire prévoit, d'une part, l'implantation d'une 5 prothèse acétabulaire en forme de coupelle semi-sphérique dans le bassin du patient et d'autre part, la résection de la tête du fémur et son remplacement par une tige dotée d'une sphère d'articulation qui s'emboîte dans la prothèse mentionnée ci-dessus. Pour positionner et fixer la prothèse acétabulaire, on utilise aujourd'hui 10 un instrument spécifique, appelé impacteur. Un tel instrument présente une tige à l'extrémité de laquelle se fixe le cotyle de remplacement. Pour manoeuvrer et positionner correctement la prothèse acétabulaire, l'impacteur doit prévoir des moyens de mise en prise sélective et de libération de la prothèse elle-même. De nos jours, on utilise différents moyens pour une telle mise en prise 15 sélective et une telle libération de la prothèse elle-même de l'impacteur. En général, on utilise des éléments d'étanchéité tels que des joints toriques ou des éléments expansibles qui agissent contre la prothèse acétabulaire. Toutefois, de tels dispositifs se sont avérés ne pas être en mesure 20 d'empêcher les glissements et les mauvais positionnements indésirés. Pour venir à bout de tels inconvénients, on trouve aujourd'hui, sur le marché, des dispositifs de mise en prise sélective et de libération de la prothèse sous forme de dents mobiles entre une position de mise en prise et une de libération. 25 En particulier, de telles dents connues sont pivotées sur charnière pour réaliser des mouvements de rotation, dans lesquels, dans la position abaissée, elles retiennent la prothèse acétabulaire sur l'impacteur. On prévoit des sièges spéciaux agencés sur la périphérie de la coupelle acétabulaire de réception des dents mobiles. 30 Toutefois, même la réalisation décrite ci-dessus à dents mobiles ne résout pas complètement les inconvénients mis en évidence ci-dessus. En effet, puisque la surface de contact entre les dents et la prothèse est limitée et à développement vertical, un effort axial, très fréquent dans les manoeuvres d'implant de la prothèse, pourrait provoquer des glissements ou encore le dégagement involontaire de la prothèse de l'impacteur. A partir de cette technique connue, le but de la présente invention est de réaliser un instrument pour l'impaction d'un composant acétabulaire pour la 5 reconstruction de l'articulation de la hanche qui soit une variante par rapport à ceux qui sont connus et qui soit particulièrement efficace. En particulier, le but de la présente invention est de réaliser l'impacteur avec un dispositif de mise en prise sélective et de libération de la prothèse acétabulaire à dents mobiles dans lequel on évite des glissements ou le dégagement involontaire de la 10 prothèse de l'impacteur. Selon l'aspect principal de la présente invention, les buts mentionnés ci-dessus sont atteints en prévoyant des éléments à dent 16 mobiles pour la translation radiale par rapport à l'axe A de la tige de manoeuvre 11 entre une position retirée de mise en prise et une position étendue de libération du composant acétabulaire 15. 15 En outre,. les dents et les sièges relatifs prévus sur la prothèse acétabulaire sont formés afin de réaliser un couplage en creux le long de la direction axiale en mesure d'empêcher tout glissement ou dégagement involontaire de la prothèse de l'impacteur le long de cette direction. Les caractéristiques et les avantages de l'instrument pour l'impaction 20 d'un composant acétabulaire pour la reconstruction de l'articulation de la hanche selon la présente invention ressortiront plus clairement suite à la lecture de la description suivante, illustrative et non limitative, en référence aux dessins joints dans lesquels: la figure 1 est une vue de l'instrument pour l'impaction d'un composant 25 acétabulaire pour la reconstruction de l'articulation de la hanche selon la présente invention; la figure 2 est une vue du dispositif de mise en prise sélective et de libération du composant acétabulaire selon la présente invention; la figure 3 est une vue en éclaté du dispositif de mise en prise sélective 30 et de libération de la figure 2; les figures 4 et 5 représentent des détails agrandis des dents du dispositif de mise en prise sélective et de libération et des sièges relatifs sur le composant acétabulaire selon la présente invention; la figure 6 représente le couplage d'une dent avec le siège relatif; la figure 7 est une vue en coupe du dispositif de mise en prise sélective et de libération de la figure 2; et la figure 8 représente un détail agrandi de la coupe de la figure 7. En référence aux figures, on indique avec le numéro de référence 10, un instrument pour l'impaction d'un composant acétabulaire pour la reconstruction de l'articulation de la hanche selon la présente invention. Un tel instrument 10 comprend une tige de manoeuvre 11 dotée au niveau d'une première extrémité, d'un dispositif 14 de mise en prise sélective et de libération du composant acétabulaire 15 et au niveau d'une seconde extrémité opposée, d'un dispositif de commande 12 du dispositif 14 de mise en prise sélective et de libération. Le dispositif 14 de mise en prise sélective et de libération est du type comprenant une pluralité d'éléments à dent 16 mobiles entre une première position de mise en prise du composant acétabulaire 15 et une seconde position de libération. En particulier, de tels éléments à dent 16 sont mobiles pour la translation radiale par rapport à l'axe A de la tige de manoeuvre 11 entre une position retirée de mise en prise et une position étendue de libération du composant acétabulaire 15.The present invention relates to an instrument for the impaction of an acetabular component for the reconstruction of the hip joint. In general, in the hip joint reconstruction operations, the operative technique provides, on the one hand, the implantation of a semi-spherical cup-shaped acetabular prosthesis in the patient's pelvis and on the other hand. on the other hand, the resection of the femoral head and its replacement by a rod with a sphere of articulation which fits into the prosthesis mentioned above. To position and fix the acetabular prosthesis, a specific instrument called an impactor is now used. Such an instrument has a rod at the end of which attaches the replacement acetabulum. To maneuver and correctly position the acetabular prosthesis, the impactor must provide means for selective engagement and release of the prosthesis itself. Nowadays, various means are used for such selective engagement and release of the prosthesis itself from the impactor. Generally, sealing elements such as O-rings or expandable members that act against the acetabular prosthesis are used. However, such devices have been found not to be able to prevent undesired slips and misplacements. To overcome such drawbacks, there are now on the market, devices for selectively engaging and releasing the prosthesis in the form of movable teeth between an engagement position and a release. In particular, such known teeth are pivoted on hinge to effect rotational movements, in which, in the lowered position, they hold the acetabular prosthesis on the impactor. Special seats are provided on the periphery of the acetabular cup for receiving moving teeth. However, even the above-described, moving-tooth embodiment does not completely solve the disadvantages highlighted above. Indeed, since the contact surface between the teeth and the prosthesis is limited and vertical development, an axial force, very common in prosthesis implant operations, could cause slippage or unintentional release of the prosthesis of the prosthesis. the impactor. From this known technique, the object of the present invention is to provide an instrument for the impaction of an acetabular component for the reconstruction of the hip joint which is an alternative to those which are known and which is particularly effective. In particular, the object of the present invention is to provide the impactor with a device for selectively engaging and releasing the acetabular prosthesis with movable teeth in which slippage or unintentional release of the prosthesis of the prosthesis is prevented. impactor. According to the main aspect of the present invention, the above-mentioned objects are achieved by providing movable tooth elements 16 for radial translation with respect to the axis A of the operating rod 11 between a withdrawn position and and an extended position of release of the acetabular component 15. In addition,. the teeth and the relative seats provided on the acetabular prosthesis are formed in order to perform a hollow coupling along the axial direction able to prevent any slipping or unintentional release of the impactor prosthesis along this direction. The characteristics and advantages of the instrument for the impaction of an acetabular component for the reconstruction of the hip joint according to the present invention will emerge more clearly after reading the following description, illustrative and not limiting, with reference to the accompanying drawings in which: Figure 1 is a view of the instrument for impactioning an acetabular component for hip joint reconstruction according to the present invention; Fig. 2 is a view of the device for selectively engaging and releasing the acetabular component according to the present invention; Fig. 3 is an exploded view of the selective engagement and release device of Fig. 2; Figures 4 and 5 show enlarged details of the teeth of the selective engagement and release device and the relative seats on the acetabular component according to the present invention; Figure 6 shows the coupling of a tooth with the relative seat; Fig. 7 is a sectional view of the selective engagement and release device of Fig. 2; and FIG. 8 shows an enlarged detail of the section of FIG. 7. Referring to FIGS, reference numeral 10 indicates an instrument for impactioning an acetabular component for reconstruction of the joint of the hip according to the present invention. Such an instrument 10 comprises an operating rod 11 provided at a first end, a device 14 for selectively engaging and releasing the acetabular component 15 and at a second opposite end, a device control 12 of the device 14 selectively engaging and releasing. The selective engagement and release device 14 is of the type comprising a plurality of tooth members 16 movable between a first engagement position of the acetabular component 15 and a second release position. In particular, such tooth elements 16 are movable for the radial translation relative to the axis A of the operating rod 11 between a withdrawn position of engagement and an extended position of release of the acetabular component 15.
Les éléments à dent 16 sont formés en forme de L avec un premier côté 19 disposé radialement par rapport à l'axe A de la tige de manoeuvre 11 et partiellement en saillie par rapport audit dispositif 14 de mise en prise sélective et de libération. Le second côté est sensiblement orthogonal par rapport au premier et 25 comprend une extrémité libre 17 tournée vers le composant acétabulaire 15. Pour éviter les glissements axiaux en condition de prise, le second côté 20 a un profil interne 18 incliné, diminué à partir de l'extrémité libre vers le premier côté qui va se coupler en prise avec une paroi correspondante inclinée du composant acétabulaire 15 afin de réaliser un couplage en creux dans la 30 direction axiale. Une telle inclinaison a varie entre 5 et 15 degrés, de préférence 10 degrés par rapport à la verticale. Le dispositif 14 de mise en prise sélective et de libération comprend un disque 21 de logement du premier côté 19 des éléments à dents 16 et un 35 élément formant curseur 22 verticalement mobile le long de l'axe A entre une première position abaissée dans laquelle les dents 16 sont en position étendue, et une position relevée dans laquelle il force les dents 16 en position retirée. De manière détaillée, les dents 16 sont suspendues pour atteindre spontanément la position étendue.The tooth members 16 are formed L-shaped with a first side 19 disposed radially with respect to the axis A of the operating rod 11 and partially projecting from said selective engagement and release device 14. The second side is substantially orthogonal to the first and has a free end 17 facing the acetabular component 15. To prevent axial slippage in the setting condition, the second side 20 has an inclined inner profile 18, decreased from the free end to the first side which will couple into engagement with an inclined corresponding wall of the acetabular component 15 to effect hollow coupling in the axial direction. Such inclination has varies between 5 and 15 degrees, preferably 10 degrees relative to the vertical. The selective engagement and release device 14 comprises a housing disk 21 for the first side 19 of the toothed elements 16 and a slider element 22 vertically movable along the axis A between a first lowered position in which the teeth 16 are in the extended position, and a raised position in which it forces the teeth 16 in the withdrawn position. In detail, the teeth 16 are suspended to spontaneously reach the extended position.
Pour forcer les dents dans la position retirée, les dents 16 et l'élément formant curseur 22 comprennent des profils inclinés conjugués 23, 24, de sorte que pendant la remontée, l'élément formant curseur 22 force les éléments à dent 16 en position retirée. La montée et la descente du curseur 22 sont commandées par un 10 élément fileté 25 passant par le disque 21 et associé par filetage à l'élément formant curseur 22, réalisant un couplage de vis - vis-mère. Un tel élément fileté 25 est commandé, d'une manière connue, par le dispositif de commande 12. Un élément à coupelle 26 de confinement du curseur 22 associé 15 inférieurement au disque 21 complète le dispositif 14 de mise en prise sélective et de libération. Comme indiqué ci-dessus, les dents et les sièges relatifs prévus sur la prothèse acétabulaire sont formés afin de réaliser un couplage en creux le long de la direction axiale en mesure d'empêcher tout glissement ou dégagement involontaire de la prothèse de l'impacteur le long de cette 20 direction. En particulier, le composant acétabulaire 15 formé comme une coupelle semi-sphérique comprend en correspondance de la base, une pluralité de sièges 30 de réception des éléments à dent 16 où de tels sièges 30 sont formés en forme de L avec le première côté 31 donnant sur l'extrémité 17 des 25 dents 16 et un second côté 32 sensiblement orthogonal par rapport au premier avec un profil externe incliné 33 vers l'extérieur pour réduire le siège. On voit ainsi qu'un instrument pour l'impaction d'un composant acétabulaire pour la reconstruction de l'articulation de la hanche selon la présente invention, réalise les buts mis en évidence au préalable.To force the teeth into the withdrawn position, the teeth 16 and the slider member 22 comprise conjugate inclined profiles 23, 24, so that during the ascent, the slider member 22 forces the tooth members 16 into the retracted position. . The raising and lowering of the slider 22 is controlled by a threaded member 25 passing through the disc 21 and threadingly associated with the slider member 22, providing a screw-to-lead coupling. Such a threaded element 25 is controlled, in a known manner, by the control device 12. A cup member 26 for confining the slider 22 associated with the disc 21 below completes the device 14 for selectively engaging and releasing. As indicated above, the teeth and the relative seats provided on the acetabular prosthesis are formed to perform a hollow coupling along the axial direction able to prevent slipping or unintentional release of the prosthesis of the impactor the along that direction. In particular, the acetabular component 15 formed as a semi-spherical cup comprises in correspondence of the base, a plurality of seats 30 for receiving the tooth elements 16 where such seats 30 are formed L-shaped with the first side 31 giving on the end 17 of the teeth 16 and a second side 32 substantially orthogonal to the first with an outwardly inclined external profile 33 to reduce the seat. It is thus seen that an instrument for the impaction of an acetabular component for the reconstruction of the hip joint according to the present invention achieves the goals previously highlighted.
30 En effet, l'instrument pour l'impaction d'un composant acétabulaire pour la reconstruction de l'articulation de la hanche selon la présente invention offre une solution en variante par rapport à celles qui sont connues, évitant les glissements ou le dégagement involontaire dans la direction axiale de la prothèse de l'impacteur.Indeed, the instrument for the impaction of an acetabular component for the reconstruction of the hip joint according to the present invention offers an alternative solution to those known, avoiding slipping or involuntary release. in the axial direction of the impactor prosthesis.
