Abstract

Device for turning the cylindrical, conical or spherical parts located at the ends of hip prostheses. The invention relates to a device making it possible quickly to adjust the concentricity of the part to be machined. It consists of a fixed part 1, of a spacer 2 and of a component support 3 as well as of a movable sleeve 4. The device according to the invention is especially intended for turning the cylindrical, conical or spherical parts located at the ends of hip prostheses.

Description

DESCRIPTION
La présente invention concerne un montage permettant de tourner, après réglage rapide de la concentricité, les parties cylindriques, coniques ou sphériques situées aux extrémités des prothèses de la hanche, sans avoir a changer le support.
DESCRIPTION
The present invention relates to an assembly making it possible to rotate, after rapid adjustment of the concentricity, the cylindrical, conical or spherical parts situated at the ends of the hip prostheses, without having to change the support.

Traditionnellement, l'usinage des prothèses de hanche était réalisé sur un tour dans un - montage fixe serre dans un mandrin à quatre mors. Une cavité a l!lntérieur du montage recevait la prothèse, celle-ci étant maintenue dans Ic montage par deux vis latérales. Le reglage dc la concentricitd dc la partie à usiner étant effectué en jouant sur les quatre mors mobiles du mandrin, opération difficile et longue à réaliser. D'autre part, cela nécessite un montage par forme et par taille de prothèse.Traditionally, the machining of hip prostheses has been carried out on a lathe in a fixed fixed clamp in a four-jaw chuck. A cavity inside the assembly received the prosthesis, the latter being held in the assembly by two lateral screws. The adjustment of the concentricity of the part to be machined is effected by playing on the four movable jaws of the mandrel, a difficult and time-consuming operation. On the other hand, this requires mounting by shape and by size of prosthesis.

Le montage, selon l'invention, permet de remédier à cet inconvénient.The assembly according to the invention overcomes this drawback.

Le dispositif comporte, en effet, deux parties mobiles a 90D l'une par rapport a l'autre (2 et 3). La prothèse à usiner (8) est maintenue par serrage (vis 5) entre les pièces (3 et 4), lesquelles sont munies d'un caoutchouc haute densité (6), ce qui permet de prendre sur le même montage toutes les formes de prothèses.The device comprises, in fact, two parts movable at 90D relative to each other (2 and 3). The prosthesis to be machined (8) is held by tightening (screws 5) between the parts (3 and 4), which are provided with a high density rubber (6), which makes it possible to take on the same assembly all the forms of prostheses.

La figure 1 représente le dispositif en coupe.Figure 1 shows the device in section.

La figure 2 représente le dispositif vue de face.FIG. 2 represents the device seen from the front.

Sur la figure 1, on remarque la partie fixe (1) qui est destinée à etre serrée dans un mandrin a trois mors à serrage concentrique (mandrin classique sur un tour). L'entretoise (2) montée en queue d'aronde sur celle-ci peut se dépla- cet de haut en bas suivant les flèches CA > . Le support (3) monté en queue d'aronde sur l'entretoise permet un déplacement de droite a gauche suivant les flèches (B), la coordination de ces deux déplacements permet de régler sans aucune difficulté la concentricité de la partie de la prothèse à tourner.In Figure 1, we note the fixed part (1) which is intended to be clamped in a three-jaw chuck with concentric clamping (conventional chuck on a lathe). The spacer (2) mounted on a dovetail thereon can move up and down according to the arrows CA>. The support (3) mounted in dovetail on the spacer allows a movement from right to left according to the arrows (B), the coordination of these two movements allows to adjust without any difficulty the concentricity of the part of the prosthesis to turn.

La machoire (4) articulee sur le support (3) autour de l'axe (7) permet la montage et le démontage de la prothèse. La vis (5) permet le blocage de celleci entre le support (3) et la machoire (4) à l'interieur desquels est ponté le caoutchouc (6). The jaw (4) articulated on the support (3) around the axis (7) allows the mounting and dismounting of the prosthesis. The screw (5) allows the blocking of this between the support (3) and the jaw (4) inside which the rubber (6) is bridged.

Le caoutchouc (6) haute densité permet de recevoir toutes sortes de prothèses sans avoir à le changer, celui-ci prenant la forme de laprothèse à usiner sous l'effet de serrage de la vis (5). The high density rubber (6) makes it possible to receive all kinds of prostheses without having to change it, the latter taking the form of the prosthesis to be machined under the tightening effect of the screw (5).
