Abstract

The present invention, which consists in preparing the femoral cavity in a single step without splintering the parts of the bones, without using so-called trial prostheses while allowing the bone debris to be collected, may be applied to all rasps in the field of orthopaedics.

Description

L'utilisation des rapes#fémorales a pour but la préparation interne de la cavité fémorale devant recevoir la prothèse définitive. Cette intervention se situe dans la partie haute du fémur, les parties tendres, os spongieux, et les parties dures, os cortical devant être parfaitement adaptées à la géométrie de l'implant final, avec ou non du jeu, soit que l'on utilise ou non un ciment de scellement os/prothèse. The purpose of the # femoral rapes is to internally prepare the femoral cavity to receive the final prosthesis. This intervention is located in the upper part of the femur, the tender parts, cancellous bone, and the hard parts, cortical bone having to be perfectly adapted to the geometry of the final implant, with or without clearance, either that is used or not a bone / prosthesis cement.

Actuellement les râpes classiques utilisées compriment lors de leur utilisation la matière enlevée ou copeau entre le corps de la râpe et l'os traité. Il est donc nécessaire de souvent dégager la râpe de la cavité et d'enlever ces débris osseux; si cette précaution d'utilisation n'est pas respectée, l'accumulation des débris entraine l'éclatement de l'os lui-même. Chaque fois que la râpe est retirée de la cavité fémorale pour la nettoyer, on introduit une prothèse d'essais correspondant à la taille exacte de la prothèse définitive choisie; suivant les cas il faut répéter cette opération plusieurs fois avant de réaliser un ajustage parfait de la prothèse d'essai avec l'os fémoral. Currently the conventional graters used compress during their use the material removed or chip between the body of the rasp and the treated bone. It is therefore often necessary to clear the rasp from the cavity and to remove these bony debris; if this precaution for use is not observed, the accumulation of debris causes the bone itself to burst. Each time the rasp is removed from the femoral cavity for cleaning, a trial prosthesis is introduced corresponding to the exact size of the chosen final prosthesis; depending on the case, this operation must be repeated several times before making a perfect adjustment of the trial prosthesis with the femoral bone.

L'utilisation d'une râpe fémorale creuse offre d'emblée plusieurs avantages intéressants pour le chirurgien. The use of a hollow femoral rasp immediately offers several interesting advantages for the surgeon.

L'opération se pratique plus franchement sans crainte d'éclatement puisque les copeaux au lieu d'être comprimés entre le corps de la râpe et la paroi fémorale sont collectés et entrainés vers l'intérieur creux du corps de la râpe. Il n'est donc pas nécessaire de retirer la râpe pour la nettoyer.L'en- foncement de la râpe se fait en une seule fois, d'ou un gain précieux de temps. La géométrie de la râpe correspondant exactement à celui de l'implant définitif t il n'est pas nécessaire d'utiliser de prothèses d'essais pour contrôler la qualité de l'ajustage. The operation is performed more frankly without fear of bursting since the shavings instead of being compressed between the body of the rasp and the femoral wall are collected and entrained towards the hollow interior of the body of the rasp. It is therefore not necessary to remove the rasp to clean it. The sinking of the rasp is done in one go, saving valuable time. The geometry of the rasp corresponds exactly to that of the final implant t it is not necessary to use trial prostheses to check the quality of the fit.

Il est possible,l'ajustage étant terminé, de collecter les débris d'os se trouvant à l'intérieur du corps de la râpe et de les utiliser comme greffons, soit directement, soit mélangés à d'autres substances (antibiotiques ou autres matières). It is possible, once the adjustment is complete, to collect the bone debris from inside the body of the rasp and use them as grafts, either directly or mixed with other substances (antibiotics or other materials). ).

La présente invention illustrée sur les 3 planches numérotées I à 3 consiste donc en une râpe creuse avec un côté amovible permettant le nettoyage des débris osseux accumulés à l'intérieur.  The present invention illustrated on the 3 plates numbered I to 3 therefore consists of a hollow rasp with a removable side allowing the cleaning of the bone debris accumulated inside.

ta planche 1/3 représente la vue gén#ral' d ens--m; de la râpe, échelle
I. Les planches 2/d et 3/3 représentent 1 dispositif amovible.your 1/3 board represents the general view # d 'of ens; rasp, scale
I. Boards 2 / d and 3/3 represent 1 removable device.

La rêpe telle que représentée à la planche I/3 est utilisée comme une râpe normale. Les débris osseux arrachés lors de l'enfoncement par les multiples arrëtes tranchantes sont acheminés directement vers l'intérieur du corps creux, grace aux trous de dégagement situés entre les arretes tranchantes. The grater as shown in Plate I / 3 is used like a normal grater. The bone debris torn off during the insertion by the multiple cutting edges is conveyed directly towards the interior of the hollow body, thanks to the clearance holes located between the cutting edges.

L'enfoncement souhaité étant obtenu, enfoncement correspondant à celui de la prothèse définitive, la râpe est retirée de la cavité fémorale. The desired insertion having been obtained, insertion corresponding to that of the final prosthesis, the rasp is removed from the femoral cavity.

En tirant la clé de verrouillage (3) vers la tête de la râpe, le couvercle (2) est libéré du corps (I); il suffit alors de le retirer du corps (I) pour nettoyer la partie creuse du corps (I), soit en jetant les débris, soit en les conservant. La râpe nettoyée, il suffit pour la rendre de nouveau opérationnelle de remettre le couvercle (2) en place, d'abord dans la partie inférieure du corps (I), puis de tirer vers la tête la clé (3) en pressant intimement le couvercle contre le corps (3) qui viendra se mettre en place dans l'alésage prévu sur le côté du couvercle (2) grâce au ressort de compression (4). By pulling the locking key (3) towards the head of the grater, the cover (2) is released from the body (I); it then suffices to remove it from the body (I) to clean the hollow part of the body (I), either by throwing away the debris, or by preserving them. The rasp cleaned, it is enough to make it operational again to replace the cover (2) in place, first in the lower part of the body (I), then to pull towards the head the key (3) by intimately pressing the cover against the body (3) which will come into place in the bore provided on the side of the cover (2) thanks to the compression spring (4).

La râpe peut être alors stérilisée et réutilisée. The grater can then be sterilized and reused.

Ce système objet de l'invention englobe l'ensemble des râpes fémorales utilisées dans le domaine de l'orthopédie.  This system which is the subject of the invention encompasses all of the femoral rasps used in the field of orthopedics.
