Description

APPAREIL POUR SUPPORTER UNE JAMBE D'UN PATIENT POUR LA CHIRURGIE DU GENOU APPARATUS FOR SUPPORTING A LEG OF A PATIENT FOR KNEE SURGERY

Domaine techniqueTechnical area

L'invention concerne un appareil destiné à être utilisé en salle d'opération, dans le domaine de la chirurgie du genou.The invention relates to an apparatus for use in the operating room, in the field of knee surgery.

Technique antérieurePrior art

L'appareil utilisé actuellement pour la chirurgie du genou comprend un vérin dont la tige supporte un axe qui s'étend transversalement à la tige de vérin et porte un berceau destiné à supporter la jambe d'un patient. Cet agencement des différents organes fait apparaître un couple latéral important formé par le poids de la jambe supportée et la longueur de l'axe portant le berceau. Ce couple étant intégralement appliqué à la tête du vérin et à sa tige, amène rapide¬ ment une détérioration et un dysfonctionnement de celui-ci. De plus, de par sa position, ce type de barre gêne le chirurgien dans l'accomplissement de son acte et rend difficile l'utilisation concomitante éventuelle d'appareils pouvant s'avérer très utiles.The apparatus currently used for knee surgery comprises a jack whose rod supports an axis which extends transversely to the jack rod and carries a cradle intended to support the leg of a patient. This arrangement of the various members reveals a significant lateral torque formed by the weight of the supported leg and the length of the axis carrying the cradle. This torque being fully applied to the head of the jack and to its rod, quickly leads to a deterioration and a malfunction thereof. In addition, due to its position, this type of bar hinders the surgeon in performing his act and makes it difficult to use any equipment that may prove very useful.

Exposé de l'inventionStatement of the invention

L'invention a pour but de remédier à ces inconvénients et à cet effet elle propose un appareil tel que défini dans les revendications.The invention aims to remedy these drawbacks and for this purpose it provides an apparatus as defined in the claims.

L'appareil suivant l'invention comprend une barre porte-berceau attachée à l'extrémité d'une manivelle couplée à la tige d'un vérin par l'intermédiaire de moyens de couplage agencés pour que le coulissement de la tige de vérin entraîne la manivelle en rotation autour d'un axe pivot.The apparatus according to the invention comprises a cradle bar attached to the end of a crank coupled to the rod of a jack by means of coupling means arranged so that the sliding of the jack rod causes the crank to rotate about a pivot axis.

Dans un mode de réalisation particulier, les moyens de couplage précités comprennent une biellette ayant une extrémité attachée par pivot à la tige du vérin tandis que l'autre extrémité de la biellette porte un axe solidaire de la manivelle.In a particular embodiment, the aforementioned coupling means comprise a link having one end pivotally attached to the rod of the jack while the other end of the link carries an axis integral with the crank.

Grâce à l'invention, le couple, néfaste mais inévita¬ ble, est neutralisé par l'axe de rotation et ses paliers. Le vérin peut donc travailler en traction ou en poussée suivant son propre axe longitudinal et sans contrainte latérale, ce qui évite les inconvénients mentionnés plus haut de l'appareil connu. De plus, la position du vérin se trouve décalée par rapport à la barre portant le berceau, et ceci dégage un espace libre appréciable pour le chirurgien ou pour le place¬ ment d'un appareil quelconque.Thanks to the invention, the torque, harmful but inevitable, is neutralized by the axis of rotation and its bearings. The actuator can therefore work in traction or in thrust along its own longitudinal axis and without lateral constraint, which avoids the drawbacks mentioned above of the known device. In addition, the position of the jack is offset relative to the bar carrying the cradle, and this creates appreciable free space for the surgeon or for the placement of any device.

Un mode de réalisation de l'inventio, est décrit dans ce qui suit à l'aide des dessins joim.s.An embodiment of the invention is described in the following using the drawings joim.s.

Description sommaire des dessinsBrief description of the drawings

La figure 1 est une vue de face d'un appareil suivant l'invention, en position déployée. La figure 2 est une vue de côté de l'appareil de la figure 1.Figure 1 is a front view of an apparatus according to the invention, in the deployed position. Figure 2 is a side view of the apparatus of Figure 1.

La figure 3 montre l'appareil de la figure 2, en posi¬ tion rétractée. Description d'un mode de réalisationFigure 3 shows the apparatus of Figure 2, in the retracted position. Description of an embodiment

Sur les dessins, le chiffre de référence 1 désigne une plaque support 1 munie d'un moyen de fixation 2 destiné à fixer l'appareil à une table d'opération. Le moyen de fixation sur la table d'opération n'est représenté qu'en exemple; il peut être différent suivant le type de table sur laquelle l'appareil doit être adapté et il n'intervient de toute façon pas dans le système. Sur la plaque support 1 est fixée une équerre 3 servant de support à un vérin 4. La tige 5 du vérin 4 est attachée par un pivot à une extrémité d'une biellette 6 dont l'autre extrémité est fixée sur un axe-pivot 7 traver¬ sant la plaque support 1. L'axe-pivot 7 est couplé à une manivelle 8 portant à son extrémité une barre 9 portant un berceau 10 destiné à supporter une jambe d'un patient. Le berceau 10 est fixé sur deux bagues 11 montées sur la barre 9.In the drawings, the reference numeral 1 designates a support plate 1 provided with a fixing means 2 intended to fix the device to an operating table. The attachment means on the operating table is only shown as an example; it can be different depending on the type of table on which the device must be adapted and it does not intervene in the system anyway. On the support plate 1 is fixed a bracket 3 serving to support a jack 4. The rod 5 of the jack 4 is attached by a pivot to one end of a link 6 whose other end is fixed on a pivot axis 7 crossing the support plate 1. The pivot axis 7 is coupled to a crank 8 carrying at its end a bar 9 carrying a cradle 10 intended to support a leg of a patient. The cradle 10 is fixed on two rings 11 mounted on the bar 9.

La commande du vérin peut se faire à partir d'un moyen quelconque, par exemple un dispositif à pédales (non représenté) connecté au vérin par le cordon 12 et géné¬ rant un signal de commande pour provoquer le déploie¬ ment du vérin et un signal de commande pour provoquer la rétraction du vérin.The actuator can be controlled from any means, for example a pedal device (not shown) connected to the actuator by the cord 12 and generating a control signal to cause the deployment of the actuator and a control signal to cause retraction of the cylinder.

Le vérin peut être d'un type quelconque, par exemple un vérin à commande électrique, hydraulique, pneumatique. Il pourrait également être remplacé par un dispositif quelconque capable de générer des mouvements rotatifs en sens contraires, par exemple un groupe motoréduc- teur.The actuator can be of any type, for example an actuator with electrical, hydraulic, pneumatic control. It could also be replaced by any device capable of generating rotary movements in opposite directions, for example a geared motor group.

Les figures 1 et 2 montrent le vérin en état déployé et l'ensemble prêt à soutenir la jambe gauche d'un pa- tient. Lorsque le vérin 3 se rétracte, la biellette 6 est entraînée en rotation vers la droite (sens horlogi¬ que) autour de l'axe longitudinal du pivot 7 et l'axe- pivot 7 entraîne à son tour la manivelle 8 en rotation vers la droite (voir figure 3) . Cette rotation dure aussi longtemps que le signal de commande appliqué au vérin ou s'arrête automatiquement après avoir décrit un certain angle (80° par exemple) grâce à un moyen quel¬ conque, par exemple un micro-interrupteur électrique intégré au vérin, une butée ou autres. Par la rotation de la manivelle 8, le berceau 7 se trouve amené dans la position désirée pour présenter la jambe du patient à l'opérant dans la position souhaitée.Figures 1 and 2 show the cylinder in the deployed state and the assembly ready to support the left leg of a pa- is holding. When the jack 3 retracts, the rod 6 is rotated to the right (clockwise) around the longitudinal axis of the pivot 7 and the pivot axis 7 in turn drives the crank 8 in rotation towards the right (see Figure 3). This rotation lasts as long as the control signal applied to the actuator or stops automatically after having described a certain angle (80 ° for example) by any means, for example an electric microswitch integrated into the actuator, a stop or others. By the rotation of the crank 8, the cradle 7 is brought into the desired position to present the patient's leg to the operator in the desired position.

Grâce à la rotation de la manivelle 8 autour de son axe-pivot 7, le vérin 4 travaille en traction ou en poussée suivant son propre axe longitudinal et sans subir aucune contrainte latérale. En outre, étant dé¬ calée par rapport à la barre ' portant le berceau 10, la position du vérin 4 dégage un espace libre appréci¬ able pour le chirurgien ou pour le placement d'un appa¬ reil quelconque.By virtue of the rotation of the crank 8 about its pivot axis 7, the jack 4 works in traction or in thrust along its own longitudinal axis and without undergoing any lateral constraint. In addition, being dé¬ wedged relative to the bar 'carrying the cradle 10, the position of the actuator 4 provides a free space appri¬ able for the surgeon or for the placement of any device.

Pour une intervention à la jambe droite, il suffit, après avoir mis le vérin en état rétracté, de faire pivoter la manivelle 8 autour de son pivot 7 jusque dans sa position décalée de 180° par rapport à la position montrée en figure 2 (vérin déployé) , et de faire pivoter le berceau 10 autour de la barre 9.For an intervention on the right leg, it suffices, after having put the jack in the retracted state, to rotate the crank 8 around its pivot 7 until in its position offset by 180 ° with respect to the position shown in FIG. 2 (jack deployed), and rotate the cradle 10 around the bar 9.

Le mode de réalisation décrit plus haut et illustré sur les dessins est un exemple donné à titre illustratif et l'invention n'est nullement limitée à cet exemple. Toute modification, toute variante et tout agencement équivalent doivent être considérés comme compris dans le cadre de 1 ' inventic The embodiment described above and illustrated in the drawings is an example given by way of illustration and the invention is in no way limited to this example. Any modification, any variant and any equivalent arrangement must be considered as part of the inventory.
