The unit comprises two identical electrically-operated jacks 14, 15 which are located at equal distances from a vertical plane containing an axis about which the platform 11 of the unit is pivotable in a transverse plane, the jacks exerting on a universal joint 8 connected to the platform forces of the same magnitude and in the same direction or in opposite directions, and a third electrically-operated jack and a pneumatic spring device disposed on opposite sides of that vertical plane.

Description

L'invention concerne une table d'opération chirugicale du genre comportant un plateau porté par un berceau monté à articulation autour d'un axe transversale de proclive-déclive et autour d'un axe longitudinal de dévers, ledit berceau étant déplaçable, pour assurer la proclive-déclive et le dévers, par deux vérins articulés au berceau par leurs extrémités supérieure et agencés de part et d'autre d'un plan verticale passant par l'axe longitudinal de dévers et dont des déplacements simultanés égaux dans le même sens assurent le réglage proclive-déclive et des déplacements simultanés égaux et et sens inverse assurent le réglage du dévers.The invention relates to a surgical operating table of the type comprising a tray carried by a cradle mounted for articulation around a transverse axis of inclination and inclination and around a longitudinal cant axis, said cradle being movable, to ensure the slope and slope, by two cylinders articulated to the cradle by their upper ends and arranged on either side of a vertical plane passing through the longitudinal axis of slope and whose equal simultaneous movements in the same direction ensure the tilt-tilt adjustment and simultaneous equal and reverse movements ensure the tilt adjustment.

Le brevet français FR-A-941 525 a pour objet une table opératoire de ce type, mais l'agencement qu'il décrit est très rudimentaire et probablement impossible à mettre en oeuvre, puisque les vérins sont articulés sur le cadre par des fentes dans chacune desquelles et montée à pivot une pièce métallique travesée à frottement doux par un tube de cadre. On voit mal comment cet agencement peut tenir compte des variations de distance entre points d'articulation lors des opérations de dévers et proclive-déclive. La présente invention vise une table opératoire à fonctionnement fiable et sûr et présentant encore une plus grande compacité des moyens de déplacement de la table, ce qui permet une plus grande commodité d'accès pour le chirurgien ainsi que pour les appareils auxiliaires utilisés en cours d'opération, par exemple des appareils radiologiques.French patent FR-A-941 525 relates to an operating table of this type, but the arrangement which it describes is very rudimentary and probably impossible to implement, since the jacks are articulated on the frame by slots in each of which and pivotally mounted a metallic piece spanned with gentle friction by a frame tube. It is difficult to see how this arrangement can take into account variations in distance between points of articulation during superelevation and declination-declination operations. The present invention relates to an operating table with reliable and safe operation and having even greater compactness of the means of movement of the table, which allows greater convenience of access for the surgeon as well as for the auxiliary devices used during surgery. operation, for example radiological devices.

Ce but est atteint, conformément à la présente invention, par la mise en oeuvre combinée des caractéristiques suivantes:

  • a) les vérins de proclive-déclive et dévers prennent appui, de façon connue en soi, sur un support intermédiaire monté à coulissement vertical et déplaçable par un troisième vérin,
  • b) le support intermédiaire consiste essentiellement en une pièce cylindrique montée à coulissement vertical sur une colonne et les vérins sont articulés par leurs extrémités inférieures sur des extensions latérales de ce support, et
  • c) le support intermédiaire comprend une tête incorporant deux tourillons transversaux formant l'axe du proclive- déclive, sur lesquels est monté un berceau intermédiaire présentant lui-même deux tourillons longitudinaux formant l'axe d'articulation de dévers du berceau portant le plateau, ladite tête formant également appui haut pour le troisième vérin.
This object is achieved, in accordance with the present invention, by the combined implementation of the following characteristics:
  • a) the tilt-and-tilt cylinders bear, in a manner known per se, on an intermediate support mounted with vertical sliding and displaceable by a third cylinder,
  • b) the intermediate support essentially consists of a cylindrical part mounted to slide vertically on a column and the jacks are articulated by their lower ends on lateral extensions of this support, and
  • c) the intermediate support comprises a head incorporating two transverse journals forming the axis of the declining-incline, on which is mounted an intermediate cradle itself having two longitudinal journals forming the cant hinge axis of the cradle carrying the plate, said head also forming a high support for the third cylinder.

Grâce au support intermédiaire articulé dans le berceau et grâce aux tourillons mis en oeuvre, on peut assurer une légère liberté d'orientation des vérins pour les réglages en dévers et proclive-déclive. Le dispositif à berceau enveloppant à articulation un support intermédiaire en forme de cylindre monté à coulissement vertical sur colonne permet de réduire au strict minimum le développement latéral des moyens de déplacement, rendant ainsi ultérieurement plus aisées les interventions du chirurgien et des appareils auxiliaires.Thanks to the intermediate support articulated in the cradle and thanks to the pins used, it is possible to ensure a slight freedom of orientation of the jacks for the tilt and tilt-tilt adjustments. The cradle device enclosing at articulation an intermediate support in the form of a cylinder mounted with vertical sliding on a column makes it possible to reduce to the strict minimum the lateral development of the means of displacement, thus subsequently making the interventions of the surgeon and auxiliary devices easier.

La mise en oeuvre d'un support intermédiaire permettant d'assurer une réduction d'amplitude des vérins est décrite dans le brevet DE-A-2260 140, mais le vérin de proclive-déclive d'une part, de dévers d'autre part, agissant séparément, doivent être de forte puissance. En outre, les vérins d'orientation prennent appui sur des articulations très écartées l'une de l'autre, de sorte que l'agencement décrit est très encombrant.The implementation of an intermediate support making it possible to ensure a reduction in the amplitude of the jacks is described in patent DE-A-2260 140, but the inclination-declination actuator on the one hand, on an overhang on the other hand , acting separately, must be of high power. In addition, the orientation jacks are supported on articulations very spaced from one another, so that the arrangement described is very bulky.

Selon une autre particularité, qui assure également une grande maniabilité de la table opératoire, la plaque d'appui de support de colonne est montée sur un pivot de rotation d'un axe vertical.According to another characteristic, which also ensures great maneuverability of the operating table, the column support support plate is mounted on a pivot pivot of a vertical axis.

D'autres caractéristiques et avantages apparaîtront au cours de la description qui va suivre.Other characteristics and advantages will appear during the description which follows.

Dans les dessins annexés montrant, à titre d'exemple non limitatif, une table d'opération chirurgicale selon l'invention:

  • -la figure 1 est une vue en élévation avec coupe partielle de la table ;
  • -la figure 2 est une représentation avec coupe partielle de la table vue selon la flèche F2 de la figure 1;
  • -la figure 3 montre le cardan privé du plateau mais muni d'un cadre de préhension;
  • -la figure 4 est une représentation avec coupe partielle de la table vue selon la flèche F4 de la figure 1.
In the accompanying drawings showing, by way of nonlimiting example, a surgical operating table according to the invention:
  • FIG 1 is an elevational view with partial section of the table;
  • FIG. 2 is a representation with partial section of the table seen according to arrow F 2 in FIG. 1;
  • FIG. 3 shows the gimbal deprived of the plate but provided with a gripping frame;
  • FIG. 4 is a representation with partial section of the table seen according to arrow F 4 in FIG. 1.

La table représentée aux figures 1 à 4 comporte un socle 1 formé d'un support 2 pouvant coulisser le long d'une colonne verticale 3 montée sur un pivot à billes 4 de sorte que la colonne et le support peuvent tourner autour d'un axe vertical Z-Z'. Selon la version désirée, table à poste fixe ou table transférable, le pivot 4 repose sur une embase 5 ancrée au sol par des chevilles 6 (moitié de gauche de la figure 2) ou sur une plan de base 5a qui repose simplement sur le sol par l'intermédiaire d'un joint d'étanchéité périphérique 7 qui empêche le passage, sous le socle, de poussières incompatibles avec l'asepsie nécessaire des salles d'opération (moitié de droite de la figure 2).The table shown in Figures 1 to 4 has a base 1 formed of a support 2 which can slide along a vertical column 3 mounted on a ball pivot 4 so that the column and the support can rotate around an axis vertical Z-Z '. Depending on the desired version, fixed station table or transferable table, the pivot 4 rests on a base 5 anchored to the ground by dowels 6 (left half of FIG. 2) or on a base plane 5a which simply rests on the ground by means of a peripheral seal 7 which prevents the passage, under the base, of dust incompatible with the necessary asepsis of the operating rooms (right half of FIG. 2).

Sur la tête 2a prévue à la partie supérieure du 2 est monté un cardan 8 constitué de deux berceaux 9 et 10 pouvant pivoter autour de deux axes sécants perpendiculaires X-X' et Y-Y'. Ce cardan supporte le plateau coulissant 11 destiné au patient et est muni, à cet effet, d'une vis de commande 12 engagée dans un écrou (non représenté).On the head 2a provided at the upper part of 2 is mounted a gimbal 8 consisting of two cradles 9 and 10 which can pivot around two perpendicular secant axes X-X 'and Y-Y'. This gimbal supports the sliding plate 11 intended for the patient and is provided, for this purpose, with a control screw 12 engaged in a nut (not shown).

L'entraînement en rotation du cardan 8, donc du plateau 11, autour des axes de dévers X-X' et de déclive-proclive Y-Y' est assuré par des vérins identiques 14 et 15 contés en parallèle et articulés, à leurs deux extremités, d'une part au berceau 10 en 14a, 15a et d'autre part au support 2 en 14b, 15b, ces extrémités étant munies de rotules diminuant ainsi les couples de frottement. Les vérins 14 et 15 sont actionnés chacun par un système moteur électrique 16 et 17 constitué d'un moteur électrique proprement dit associé ou non à un réducteur-inverseur. Ces systèmes moteurs sont surmoulés de façon hermétique pour répondre aux normes en vigueur concernant les risques d'explosion en bloc opératoire. Les deux vérins 14 et 15 ainsi que leurs systèmes d'actionnement associés 16 et 17 sont disposés de chaque côté du plan vertical passant par l'axe X-X' à égale distance de ce plan.The drive in rotation of the gimbal 8, therefore of the plate 11, around the superelevation axes XX ′ and of declination-inclination YY ′ is ensured by identical jacks 14 and 15 counted in parallel and articulated, at their two ends, of on the one hand to the cradle 10 at 14a, 15a and on the other hand to the support 2 at 14b , 15b , these ends being provided with ball joints thus reducing the friction couples. The cylinders 14 and 15 are each actuated by an electric motor system 16 and 17 consisting of an electric motor proper associated or not with a reduction gearbox. These motor systems are hermetically molded to meet the standards in force concerning the risks of explosion in the operating room. The two jacks 14 and 15 as well as their associated actuation systems 16 and 17 are arranged on each side of the vertical plane passing through the axis XX 'at equal distance from this plane.

L'entraînement en translation verticale du support 2 le long de la colonne 3 est assuré par un vérin 18 qui prend appui d'une part par une butée ou analogue 18a sous la tête 2a du support 2 et d'autre part, par l'intermédiaire d'entretoises 18b, sur une plaque d'appui 21 qui repose sur l'embase 5 (ou la plaque de base 5a selon la version adoptée) par l'intermédiaire du pivot 4. Le vérin 18 est actionné, comme les vérins 14 et 15, par un système moteur électrique 19 identique aux systèmes 16 et 17 et comme eux surmoulé. Au vérin 18 est associé un ressort pneumatique 20 dont l'extrémité supérieure 20a est fixée, par un axe, sous la tête 2a du support 2 tandis que son extrémité inférieure 20b repose sur la plaque d'appui 21. Le vérin 18 et le ressort pneumatique 20 sont disposés de part et d'autre du plan vertical passant par l'axe X-X' de dévers, à égale distance de ce plan et à l'opposé des vérins 14 et 15 par rapport au plan vertical passant par l'axe de déclive-proclive Y-Y'.The drive in vertical translation of the support 2 along the column 3 is ensured by a jack 18 which bears on the one hand by a stop or the like 18a under the head 2a of the support 2 and on the other hand, by the intermediate spacers 18 b , on a support plate 21 which rests on the base 5 (or the base plate 5a depending on the version adopted) by means of the pivot 4. The jack 18 is actuated, like the jacks 14 and 15, by an electric motor system 19 identical to systems 16 and 17 and like them overmolded. The jack 18 is associated with a pneumatic spring 20, the upper end 20a of which is fixed, by an axis, under the head 2a of the support 2 while its lower end 20b rests on the support plate 21. The jack 18 and the pneumatic spring 20 are arranged on either side of the vertical plane passing through the cant XX ', at equal distance from this plane and opposite the jacks 14 and 15 relative to the vertical plane passing through the axis declining-proclive Y-Y '.

L'alimentation en courant électrique des systèmes moteurs 16, 17 et 19 est assurée par une source de courant autonome formée de deux batteries rechargeables 22 à basse tension, par exemple 24 volts.The electric current supply to the motor systems 16, 17 and 19 is ensured by an autonomous current source formed by two rechargeable batteries 22 at low voltage, for example 24 volts.

Ces batteries ont une capacité suffisante pour assurer à la table une autonomie d'une journée opératoire, donnant ainsi au chirurgien la plus grande sécurité. Ces batteries doivent cependant être régulièrement rechargées, généralement en dehors des temps opératoires. Elles sont reliées, à cet effet, par un câble électrique 23 qui s'enroule sur un enrouleur automatique 24 monté sur le support 2, à un chargeur 25. La longueur donnée au fil 23 permet, s'il est nécessaire d'effectuer une recharge des batteries au cours d'un programme opératoire, de placer le chargeur hors de la salle d'opération. L'atmosphère de ces salles est en effet souvent chargée de gaz anesthésiques et toute possibilité d'explosion à la suite d'étincelles électriques est ainsi évitée.These batteries have sufficient capacity to provide the table with an autonomy of one operating day, thus giving the surgeon the greatest security. These batteries must however be regularly recharged, generally outside operating times. They are connected, for this purpose, by an electric cable 23 which is wound on an automatic reel 24 mounted on the support 2, to a charger 25. The length given to the wire 23 allows, if it is necessary to carry out a recharge the batteries during an operating program, place the charger outside the operating room. The atmosphere in these rooms is indeed often charged with anesthetic gases and any possibility of explosion following electrical sparks is thus avoided.

Pour éviter le salissement des divers composants de la table lors d'interventions urologiques par exemple ou des projections inévitables de produits antiseptiques lors du nettoyage des salles, il est prévu, à la base du socle 1, des capots protecteurs 26 (version fixe, moitié de gauche de la figure 2) ou 27 (version transférable, moitié de droite de la figure 2) ainsi qu'un capot télescopique étanche 28 coiffant l'ensemble desdits éléments.To prevent the various components of the table from becoming dirty during urological interventions, for example, or inevitable projections of antiseptic products when cleaning the rooms, protective covers 26 are provided at the base of the base 1 (fixed version, half left of Figure 2) or 27 (transferable version, right half of Figure 2) and a sealed telescopic cover 28 covering all of said elements.

Il peut être nécessaire de déplacer la table et avantageux d'utiliser pour cela un chariot- transfert. On munit à cet effet le socle 1 d'un cadre amovible 29 fixé momentanément sur le cardan 8 (figure 3) par des broches 30 et assuré par des organes de serrage (non représentés).It may be necessary to move the table and it is advantageous to use a transfer trolley for this. To this end, the base 1 is provided with a removable frame 29 temporarily attached to the gimbal 8 (FIG. 3) by pins 30 and provided by clamping members (not shown).

Le fonctionnement de la table est le suivant:The operation of the table is as follows:

Pour entraîner le plateau en rotation autour de l'axe Y-Y', c'est-à-dire pour lui donner un mouvement de déclive ou de proclive, on commande les systèmes moteurs électriques 16 et 17 de façon que les deux vérins 14 et 15 agissent simultanément dans le même sens, c'est-à-dire que leurs tiges s'étendent ou se rétractent de la même quantité. Les deux vérins développent alors la même force, chacune étant égale à la moitié de celle qui est nécessaire pour vaincre les couples résistants.To drive the plate in rotation around the axis Y-Y ′, that is to say to give it a declining or inclining movement, the electric motor systems 16 and 17 are controlled so that the two jacks 14 and 15 act simultaneously in the same direction, that is to say that their rods extend or retract by the same amount. The two cylinders then develop the same force, each being equal to half of that which is necessary to overcome the resistant couples.

Pour entraîner le plateau en rotation autour de l'axe X-X', c'est-à-dire pour lui donner un mouvement de dévers droite ou gauche, on commande les systèmes moteurs 16 et 17 de façon que les vérins 14 et 15 agissent simultanément mais en sens contraire, c'est-à-dire que pendant que l'une des tiges s'étend l'autre se rétracte de la même quantité. Les deux vérins développent alors deux forces de même intensité mais de signe contraire, chacune de ces forces étant égale à la moitié de celle qui est nécessaire pour vaincre les couples résistants.To drive the plate in rotation around the axis XX ', that is to say to give it a right or left cant movement, the motor systems 16 and 17 are controlled so that the jacks 14 and 15 act simultaneously but in the opposite direction, that is to say that while one of the rods extends the other retracts by the same amount. The two jacks then develop two forces of the same intensity but of opposite sign, each of these forces being equal to half of that which is necessary to overcome the resistant couples.

Pour faire monter le plateau ou l'abaisser, on commande le système moteur 19 de façon que la tige du vérin 18 s'étende ou se rétracte, entraînant le support 2 le long de la colonne 3. La combinaison avec ce vérin du ressort 20 permet d'emmagasiner dans ledit ressort, lors du mouvement de descente, une énergie qui résulte du poids de l'ensemble mobile et qui est restituée lors du mouvement ce montée. Les efforts demandés au vérin et au ressort pour un mouvement ascensionnel sont sensiblement égaux, chacun d'eux étant sensiblement égal à la moitié de celui qui serait nécessaire avec un vérin unique.To raise or lower the plate, the motor system 19 is controlled so that the rod of the jack 18 extends or retracts, driving the support 2 along the column 3. The combination with this jack of the spring 20 makes it possible to store in said spring, during the downward movement, an energy which results from the weight of the mobile assembly and which is restored during the movement of this upward movement. The forces required on the cylinder and the spring for an upward movement are substantially equal, each of them being substantially equal to half of that which would be necessary with a single cylinder.

Le montage rotatif de la colonne joint au fait que les batteries 22 en sont solidaires permet une rotation illimitée du plateau autour de l'axe Z-Z', offrant ainsi le maximum de commodité au chirurgien. On peut bien entendu prévoir une pédale de blocage (non représentée) pour fixer le plateau dans l'orientation choisie.The rotary mounting of the column joined to the fact that the batteries 22 are integral with it allows unlimited rotation of the plate around the axis Z-Z ', thus offering maximum convenience to the surgeon. It is of course possible to provide a locking pedal (not shown) for fixing the plate in the chosen orientation.

Il convient de remarquer qu'il est toujours possible de passer de la version fixe à la version mobile ou de la version mobile à la version fixe de la table en changeant l'embase 5 pour une plaque de bàse 5a ou inversement.It should be noted that it is always possible to switch from the fixed version to the mobile version or from the mobile version to the fixed version of the table by changing the base 5 for a base plate 5a or vice versa.

Pour déplacer l'ensemble du socle 1 au moyen d'un chariot de transfert habituellement utilisé pour les plateaux, on engage la fourche (non représentée) de ce chariot sous le cadre 29, une manoeuvre de descente du socle a alors pour effet d'amener la partie inférieure du cadre en contact avec ladite fourche puis grâce à cet appui, en continuant la manoeuvre de descente, le socle se soulève par rapport au sol jusqu'en fin de course. L'ensemble socle-chariot peut alors être déplacé et orienté selon les besoins de l'utilisateur.To move the whole of the base 1 by means of a transfer carriage usually used for the trays, the fork (not shown) of this carriage is engaged under the frame 29, a maneuver for lowering the base then has the effect of bring the lower part of the frame into contact with said fork and then with this support, continuing the descent maneuver, the base is raised relative to the ground until the end of the race. The pedestal-cart assembly can then be moved and oriented according to the user's needs.

De nombreuses variantes peuvent être apportées au mode de réalisation décrit et représenté sans pour autant sortir du cadre de l'invention.Many variations can be made to the embodiment described and shown without departing from the scope of the invention.

C'est ainsi par exemple que l'on pourrait utiliser pour le ressort 20 un ressort hydraulique ou un ressort mécanique, que les vérins, au lieu d'être des vérins à billes pourraient être munis d'une liaison antifriction d'un autre type, etc...Thus, for example, one could use for the spring 20 a hydraulic spring or a mechanical spring, that the jacks, instead of being ball jacks, could be provided with an antifriction connection of another type. , etc ...
