Abstract

The assembly neck (1) for a femoral prosthesis has a quick connector assembly nail (3) fitting into the medullary canal of the bone. The nail has two upper blind bores (4,5) receiving pins (6,7) on the neck. One pin (6) can pivot around an axis orthogonal to its length and is biased into a set position by an elastic insert (12).

Description

L'invention se rapporte à un col d'essai d'une prothèse fémorale, équipé d'un dispositif d'assemblage rapide. The invention relates to a test neck of a femoral prosthesis, equipped with a rapid assembly device.

Depuis déjà de nombreuses années, il est habituel de substituer à l'articulation, notamment du fémur, sur le bassin tout ou partie de cette articulation. For many years now, it has been customary to substitute for the joint, particularly the femur, on the pelvis all or part of this articulation.

On peut donc remplacer la tête du fémur ou le cotyle de l'acétabulum ou encore ces deux éléments d'articulation. We can replace the head of the femur or acetabulum acetabulum or these two elements of articulation.

L'invention se rapporte plus précisément à la mise en place d'une prothèse fémorale. The invention relates more specifically to the establishment of a femoral prosthesis.

La prothèse choisie doit être adaptée à la morphologie du patient et, notamment, à la longueur du col fémoral. The chosen prosthesis must be adapted to the morphology of the patient and, in particular, to the length of the femoral neck.

Si le chirurgien dispose d'une gamme de prothèse fémorale, il doit cependant réaliser un certain nombre d'essai avant d'en sélectionner une et de la poser définitivement. If the surgeon has a range of femoral prosthesis, however, it must perform a number of tests before selecting one and put it permanently.

Pour la mise en place de cette prothèse, après avoir supprimé la tête fémorale, le chirurgien doit aménager la cavité médullaire à l'aide d'une râpe dont la conformation est très proche de la tige de la prothèse qu'il va engager dans le canal médullaire du fémur. For the placement of this prosthesis, after having removed the femoral head, the surgeon must arrange the medullary cavity with a rasp whose conformation is very close to the stem of the prosthesis that it will engage in the medullary canal of the femur.

Pour procéder aux essais précités et, notamment, au choix de la tête fémorale, il est connu (FR-A-2.660.857, EP-A-0.428.303, WO-A-89104238) de prévoir que le manche de la râpe soit amovible et puisse être remplacé provisoirement par une tête d'essai . In order to carry out the abovementioned tests and, in particular, the choice of the femoral head, it is known (FR-A-2,660,857, EP-A-0,428,303, WO-A-89104238) to provide that the handle of the rasp is removable and can be temporarily replaced by a test head.

Pour ce faire, on prévoit entre les deux pièces concernées un dispositif d'assemblage rapide du type à emboîtement selon une direction perpendiculaire au plan de joint des deux pièces et un moyen de verrouillage en translation de cet emboîtement pour éviter le désaccouplement non volontaire. Egalement, il faut obtenir une immobilisation en rotation des deux pièces dans le plan de joint. To do this, there is provided between the two parts concerned a quick assembly device type interlocking in a direction perpendicular to the joint plane of the two parts and a locking means in translation of this interlocking to avoid unwanted uncoupling. Also, it is necessary to immobilize the two parts in rotation in the joint plane.

A cet effet, il est connu de faire appel à un dispositif d'assemblage comprenant -d'une part, pour l'emboîtement présentés par une des deux pièces, deux trous borgnes distincts débouchant dans le plan de joint et écartés l'un de l'autre d'une valeur prédéterminée, . portés par l'autre pièce, deux doigts lesquels sont destinés à être engagés chacun dans un des trous borgnes précités et - d'autre part, pour le verrouillage en translation selon la direction d'emboitement . présentée par l'un des doigts, un empreinte coopérant avec une butée en saillie par rapport à la face cylindrique interne du trou borgne recevant le doigt avec son empreinte et . un moyen pour augmenter, momentanément, l'écart entre la face active de la butée et l'empreinte précitée et ainsi autoriser la translation du doigt dans le trou borgne. For this purpose, it is known to use an assembly device comprising - on the one hand, for the interlocking presented by one of the two parts, two separate blind holes opening into the joint plane and spaced apart one of the other of a predetermined value,. carried by the other part, two fingers which are intended to be each engaged in one of the aforementioned blind holes and - secondly, for locking in translation in the direction of interlocking. presented by one of the fingers, a recess cooperating with an abutment projecting from the inner cylindrical face of the blind hole receiving the finger with its imprint and. a means for temporarily increasing the difference between the active face of the abutment and the aforementioned impression and thus allow the translation of the finger in the blind hole.

Selon le mode de réalisation connu (FR-A-2.660.857), d'une part, le doigt pourvu de son empreinte est mobile en rotation autour de son axe longitudinal et, d'autre part, l'empreinte est réalisée par une gorge annulaire dont la profondeur varie pour former une came de sorte que selon la position angulaire de ce doigt, le verrouillage est actif ou inactif. According to the known embodiment (FR-A-2,660,857), on the one hand, the finger provided with its fingerprint is rotatable about its longitudinal axis and, on the other hand, the fingerprint is made by a annular groove whose depth varies to form a cam so that according to the angular position of the finger, the lock is active or inactive.

Pour sa manoeuvre, l'utilisateur agit sur un moyen d'indexation couplé au doigt. For its operation, the user acts on an indexing means coupled to the finger.

Chaque tête d' essai de fémur doit alors être équipée du dispositif précité. Ce dispositif reste donc coûteux à produire et pose par ailleurs le problème de la multiplicité des pièces. Each femoral test head must then be equipped with the aforementioned device. This device is therefore expensive to produce and also poses the problem of the multiplicity of parts.

Un des résultats que l'invention vise à obtenir est un col d'essai qui offre une grande souplesse d'utilisation. One of the results that the invention aims to achieve is a test collar that offers great flexibility of use.

A cet effet, l'invention a pour objet un col d'essai d'une prothèse fémorale, équipé d'un dispositif d'assemblage rapide sur une pièce engagée provisoirement dans le canal médullaire d'un os, lequel dispositif d'assemblage comprend -d'une part, pour l'emboîtement présentés par une des deux pièces, deux trous borgnes distincts débouchant dans le plan de joint et écartés l'un de l'autre d'une valeur prédéterminée, portés par l'autre pièce, deux doigts lesquels sont destinés à être engagés chacun dans un des trous borgnes précités et - d'autre part, pour le verrouillage en translation selon la direction d'emboitement . présentée par l'un des doigts, un empreinte coopérant avec une butée en saillie par rapport à la face cylindrique interne du trou borgne recevant le doigt avec son empreinte et . un moyen pour augmenter, momentanément, l'écart entre la face active de la butée et l'empreinte précitée et ainsi autoriser la translation du doigt dans le trou borgne, ce col d'essai étant caractérisé en ce que - le doigt pourvu de son empreinte est articulé sur un axe situé dans un plan orthogonal à l'axe longitudinal du doigt de sorte que ce doigt puisse basculer dans un plan contenant l'axe longitudinal du dit doigt, - le jeu de fonctionnement entre le doigt et la face interne cylindrique du trou borgne est au moins suffisant pour laisser s'échapper l'empreinte de la butée et - ce col d'essai loge un moyen élastique développant une force prédéterminée sollicitant l'empreinte du doigt articulé vers la butée. For this purpose, the subject of the invention is a test neck of a femoral prosthesis, equipped with a device for rapid assembly on a part temporarily engaged in the medullary canal of a bone, which assembly device comprises on the one hand, for the interlocking presented by one of the two parts, two distinct blind holes opening into the joint plane and spaced from one another by a predetermined value, carried by the other part, two fingers which are intended to be each engaged in one of the aforementioned blind holes and - secondly, for locking in translation in the direction of interlocking. presented by one of the fingers, a recess cooperating with an abutment projecting from the inner cylindrical face of the blind hole receiving the finger with its imprint and. a means for temporarily increasing the difference between the active face of the abutment and the aforementioned impression and thus allowing the translation of the finger in the blind hole, this test neck being characterized in that - the finger provided with its impression is articulated on an axis located in a plane orthogonal to the longitudinal axis of the finger so that the finger can tilt in a plane containing the longitudinal axis of said finger, - the operating clearance between the finger and the cylindrical inner face the blind hole is at least sufficient to let out the impression of the stop and - this test neck houses an elastic means developing a predetermined force urging the fingerprint hinged to the stop.

L'invention sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement - figures 1 et 2 : deux vues en coupe partielle du col d'essai en cours d'assemblage, - figure 3 : une coupe en gros plan du col d'essai. En se reportant au dessin, on voit un col d'essai 1 équipé d'un dispositif 2 d'assemblage rapide sur une pièce 3 engagée provisoirement dans le canal médullaire d'un os. Cette pièce 3 engagée provisoirement dans le canal médullaire est une râpe destinée à creuser le logement devant recevoir à demeure la tige fémorale de la prothèse. The invention will be better understood using the following description given by way of non-limiting example with reference to the accompanying drawing which shows schematically - Figures 1 and 2: two views in partial section of the test neck during assembly, - Figure 3: a close-up section of the test collar. Referring to the drawing, there is shown a test neck 1 equipped with a device 2 for rapid assembly on a part 3 temporarily engaged in the medullary canal of a bone. This piece 3 temporarily engaged in the medullary canal is a rasp intended to dig the housing to receive permanently the femoral stem of the prosthesis.

Le dispositif d'assemblage équipant ce col d'essai comprend - d'une part, pour l'emboîtement . présentés par une des deux pièces, que sont le col d'essai 1 et la pièce engagée dans le canal médullaire, deux trous 4, 5 borgnes distincts débouchant dans le plan de joint et écartés l'un de l'autre d'une valeur prédéterminée, . portés par l'autre pièce, deux doigts 6, 7, lesquels sont destinés à être engagés chacun dans un des trous borgnes précités et - d'autre part, pour le verrouillage en translation selon la direction d'emboitement . présentée par l'un (6) des doigts 6, 7, un empreinte 8 coopérant avec une butée 9 en saillie par rapport à la face cylindrique interne du trou borgne recevant le doigt avec son empreinte et . un moyen pour augmenter, momentanément, l'écart entre la face active de la butée et l'empreinte précitée et ainsi autoriser la translation du doigt dans le trou borgne. The assembly device equipping this test collar comprises - on the one hand, for the interlocking. presented by one of the two parts, that is the test neck 1 and the part engaged in the medullary canal, two separate holes 4, 5 blind opening into the joint plane and spaced apart from each other by a value predetermined, carried by the other part, two fingers 6, 7, which are each intended to be engaged in one of the aforementioned blind holes and - secondly, for locking in translation in the direction of interlocking. presented by one (6) of the fingers 6, 7, a cavity 8 cooperating with an abutment 9 projecting from the internal cylindrical face of the blind hole receiving the finger with its imprint and. a means for temporarily increasing the difference between the active face of the abutment and the aforementioned impression and thus allow the translation of the finger in the blind hole.

Selon une caractéristique de l'invention - le doigt 6 pourvu de son empreinte 8 est articulé sur un axe 10 situé dans un plan orthogonal à l'axe 11 longitudinal du doigt de sorte que ce doigt puisse basculer dans un plan contenant l'axe longitudinal du dit doigt, - le jeu de fonctionnement entre le doigt et la face interne cylindrique du trou borgne est au moins suffisant pour laisser s'échapper l'empreinte de la butée et - ce col d'essai loge un moyen 12 élastique développant une force prédéterminée sollicitant l'empreinte du doigt articulé vers la butée. According to a feature of the invention - the finger 6 provided with its fingerprint 8 is articulated on an axis 10 situated in a plane orthogonal to the longitudinal axis 11 of the finger so that the finger can tilt in a plane containing the longitudinal axis of said finger, - the operating clearance between the finger and the cylindrical inner face of the blind hole is at least sufficient to let out the impression of the abutment and - this test neck houses an elastic means 12 developing a force predetermined biasing the fingerprint hinged to the stop.

Par simple choix de la raideur du ressort, on détermine la force de l'accouplement. By simply choosing the stiffness of the spring, the force of the coupling is determined.

L'utilisateur n'a plus besoin d'agir sur un organe séparé de verrou i<B>l</B> lageldéverrouillage pour mettre en place le col d'essai ou le retirer. Avantageusement, l'extrémité du col d'essai présente une portée tronconique 15 sur laquelle s'emboîte de manière amovible une tête 16 dite d'essai globalement cylindrique qui présente une cavité 17, également tronconique, venant coiffer la portée tronconique du col d'essai. The user no longer needs to act on a separate lock member to lock the test collar or remove it. Advantageously, the end of the test neck has a frustoconical bearing surface 15 on which detachably fits a generally cylindrical test head 16 which has a cavity 17, also frustoconical, which caps the frustoconical bearing surface of the neck. trial.

Cela permet, à l'aide d'un seul col d'essai et d'une pluralité de têtes d'essai, de couvrir toute la gamme de prothèse. This allows, with the aid of a single test collar and a plurality of test heads, to cover the entire range of prosthesis.

Dans la forme de réalisation représentée, le col d'essai présente une embase 18 logeant, dans une cavité 19, l'extrémité dite proximale du doigt 6 mobile et l'axe d'articulation de ce doigt. In the embodiment shown, the test neck has a base 18 housing, in a cavity 19, the so-called proximal end of the movable finger 6 and the axis of articulation of this finger.

L'axe 10 d'articulation de ce doigt est déporté de l'extrémité proximale d'une valeur suffisante pour loger au fond de la cavité le ressort 12 qui sollicite le doigt vers la butée. The axis 10 of articulation of this finger is offset from the proximal end by a value sufficient to accommodate the bottom of the cavity the spring 12 which urges the finger towards the stop.

La partie proximale du doigt présente une face 30 plane d'appui du ressort. La butée est constituée par une surface courbe et, de préférence, une surface cylindrique de révolution. The proximal portion of the finger has a planar face 30 of the spring. The stop is constituted by a curved surface and, preferably, a cylindrical surface of revolution.

Notamment, pour des raisons de fabrication, cette butée est présentée par un organe 20 logé dans un canal 21, lequel débouche radialement dans le trou borgne recevant le doigt. In particular, for manufacturing reasons, this stop is presented by a member 20 housed in a channel 21, which opens radially into the blind hole receiving the finger.

Lorsque les doigts sont engagés dans les trous borgnes, le doigt fixe appuie par une génératrice sur l'organe mobile qui fait ainsi saillie dans le trou borgne. When the fingers are engaged in the blind holes, the fixed finger is supported by a generator on the movable member which thus projects into the blind hole.

Un chanfrein 22 réalisé au niveau de l'extrémité distale du doigt articulé facilite l'échappement du doigt lors de l'opération d'emboitement. A chamfer 22 made at the distal end of the articulated finger facilitates the escape of the finger during the interlocking operation.
