Description

APPAREIL DE MOBILISATION ARTICULAIRE PASSIVE CONTINUE DU PIED DU NOUVEAU-NE ET DE L'ENFANTCONTINUOUS PASSIVE JOINT MOBILIZATION APPARATUS FOR NEWBORN AND CHILD'S FOOT
DOMAINE TECHNIQUE :TECHNICAL AREA :
L'invention concerne le domaine technique de la mobilisation articulaire, en vue de la correction orthopétique du pied chez le nouveau-né et l'enfant.The invention relates to the technical field of joint mobilization, for the orthopetic correction of the foot in newborns and children.
L'appareil permet de mobiliser un pied ou les deux pieds, simultanément, dans les trois plans perpendiculaires de l'espace. La définition des mouvements du corps et de ceux du pied s'effectue conventionnelle ent par rapport à trois plans perpendiculaires de l'espace qui sont illustrés par la fig. 1. Il s'agit : - du plan sagittal (_S) ou médian antéro-postérieur,The device makes it possible to mobilize one or both feet simultaneously in the three perpendicular planes of space. The definition of the movements of the body and those of the foot is carried out conventionally with respect to three perpendicular planes of space which are illustrated in FIG. 1. These are: - the sagittal (_S) or median anteroposterior plane,
- du plan frontal (_F),- the frontal plane (_F),
- et du plan transversal horizontal (T) .- and the horizontal transverse plane (T).
Ces trois plans déterminent trois axes de mobilisation A-A', B-B* et C-C* qui peuvent être rapportés aux articulations du pied, comme cela est montré par la fig. 2.These three planes determine three axes of mobilization A-A ', B-B * and C-C * which can be related to the joints of the foot, as shown in fig. 2.
L'axe A-A' est celui de la flexion dorsale-flexion plantaire du pied, tel que schématisé en fig. 3. La flexion est dite dorsale quand la face dorsale du pied se rapproche de la face antérieure de la jambe. La flexion est dite plantaire quand la face dorsale du pied s'éloigne de la face antérieure de la jambe. Le pied est alors dit en équin.The axis A-A 'is that of the dorsal flexion-plantar flexion of the foot, as shown diagrammatically in FIG. 3. Flexion is said to be dorsal when the dorsal side of the foot approaches the front side of the leg. Flexion is said to be plantar when the dorsal side of the foot moves away from the front side of the leg. The foot is then said in equine.
L'axe B-B' est celui de la supination-pronation ou du varus-valgus, comme montré par la fig. 4. Le pied est dit en varus ou supination quand la plante du pied regarde l'axe médian du corps. Le pied est dit en valgus ou pronation quand La plante du pied regarde Latéralement.The axis B-B 'is that of supination-pronation or varus-valgus, as shown in fig. 4. The foot is said to be in varus or supination when the sole of the foot looks at the median axis of the body. The foot is said to be in valgus or pronation when the sole of the foot looks sideways.
L'axe C-C* est celui de l'abduction-adduction, illustré par la fig. 5. Le pied est dit en adduction quand son axe longitudinal antéro-postérieur se dirige vers l'axe médian du corps. Le pied est dit en abduction quand son axe longitudinal s'éloigne du plan médian du corps.The axis CC * is that of the abduction-adduction, illustrated by fig. 5. The foot is said to be adductive when its anteroposterior longitudinal axis goes towards the median axis of the body. The foot is said to be abducted when its longitudinal axis moves away from the median plane of the body.
Il est fréquent de rencontrer des malformations anatomiques du pied, particulièrement le pied bot varus équin, c'est-à-dire adoptant naturellement une position en adduction, en varus et en équin. De telles malformations combinées sont, dans 50 % des cas, bilatérales. Il est considéré que de telles malformations peuvent être corrigées, au moins en partie, par mobilisation articulaire passive continue.It is common to encounter anatomical malformations of the foot, particularly the club foot equus varus, that is to say naturally adopting a position in adduction, varus and equine. Such combined malformations are, in 50% of cases, bilateral. It is believed that such malformations can be corrected, at least in part, by continuous passive joint mobilization.
TECHNIQUE ANTERIEURE :PRIOR TECHNIQUE:
On connaît un appareil, dit de mécanothérapie, qui permet la mobilisation active ou activo-passive du pied dans Les trois axes perpendiculaires de l'espace. Cet appareil, dit de Franco, ne rentre pas dans Le cadre de La mobilisation articulaire passive continue.We know a device, called mechanotherapy, which allows the active or activo-passive mobilization of the foot in the three perpendicular axes of space. This device, known as Franco, does not fall within the framework of Passive joint mobilization continues.
On connaît des appareils de positionnement du pied en vue de la correction orthopédique. Ces appareils ne rentrent pas non plus dans le domaine de La mobilisation articulaire passive continue.Foot positioning devices are known for orthopedic correction. These devices do not fall into the area of continuous passive joint mobilization.
On connaît, également, des appareils de mobilisation passive continue du pied. Ces appareils dits Mobil mb et commercialisés par La Société TORONTO MEDICAL Cie, ne mobilisent Le pied qu'en flexion dorsale-flexion plantaire. On connaît, enfin, par une demande de brevetThere are also known devices for continuous passive mobilization of the foot. These so-called Mobil mb devices, marketed by TORONTO MEDICAL Cie, only mobilize the foot in dorsal flexion-plantar flexion. We know, finally, by a patent application
FR 88-09 701, un appareil de mobilisation passive continue du pied sur Les trois axes A-A', B-B' et C-C Cet appareil ne permet de mobiliser qu'un seul pied à La fois. Le traitement simultané, symétrique ou non, des deux pieds est donc exclu. Le second inconvénient que présente cet appareil réside dans le fait que le second pied, ne Lui étant pas solidarisé pendant La phase de correction du premier, l'enfant conserve la possibilité d'effectuer des mouvements de rotation ou reptation qui risquent d'annuler La correction orthopédique recherchée. L'objet de L'invention est de remédier aux inconvénients ci-dessus en proposant un nouvel appareil conçu pour combler Les Lacunes des appareils existants et pour permettre, au contraire, la mobilisation, indifféremment, d'un seul pied ou des deux pieds simultanément. Un des objectifs de La présente invention est d'offrir un appareil de mobilisation permettant, dans Le cas où un seul pied doit être mobilisé, de conserver l'autre pied solidarisé à l'appareil, quels que soient les mouvements de L'enfant, et aux membres inférieurs de se placer en une position symétrique autorisant une mobilisation correctrice.FR 88-09 701, a continuous passive mobilization device for the foot on the three axes A-A ', BB' and CC This device can only mobilize one foot at a time. The simultaneous treatment, symmetrical or not, of the two feet is therefore excluded. The second drawback that this device presents lies in the fact that the second foot, not being joined to it during the correction phase of the first, the child retains the possibility of performing rotational or crawling movements which risk canceling out the orthopedic correction sought. The object of the invention is to remedy the drawbacks above by proposing a new device designed to fill the gaps in existing devices and to allow, on the contrary, the mobilization, indifferently, of one foot or both feet simultaneously. One of the objectives of the present invention is to offer a mobilization device making it possible, in the case where a single foot must be mobilized, to keep the other foot secured to the device, whatever the movements of the child and the lower limbs to be placed in a symmetrical position allowing corrective mobilization.
L'appareil selon l'invention est, en outre, conçu de manière qu'il puisse être, soit posé sur socle, soit suspendu. Dans ce dernier cas, l'enfant peut effectuer des mouvements actifs de flexion-extension des membres inférieurs, ce qui permet L'entretien ou le développement de son système muscuLaire.The apparatus according to the invention is also designed so that it can either be placed on a base or suspended.

Le moteur 14 est monté sur Le berceau 10 et porte, par son arbre de sortie, un pignon denté 15 engrenant en permanence avec une roue dentée 16 tournant sur un axe Y_ et avec Laquelle il forme un train réducteur. Le système d'actionnement comprend aussi un dispositif de transformation du mouvement de rotation angulaire partielle de l'organe moteur en un mouvement recti Ligne alternatif. Ce dispositif de transformation se compose d'un support 17 solidaire de La roue 16 et sur Lequel sont montées, en deux étages superposés, deux paires 18a-18b et 19a-19b de tiges au moins en partie filetées et susceptibles d'être commandées en rotation chacune par un bouton 20. Les tiges 18a-18b et 19a-19b s'étendent parallèlement entre elles, de part et d'autre de l'axe y_ en étant disposées également de part et d'autre dudit axe dans chaque paire. Les tiges 18a-18b et 19a-19b supportent chacune un curseur taraudé 21jî-21fc) et 22a-22b dont la position axiale peut être réglée par rotation de La tige correspondante au moyen du bouton 20. A partir du support 17 s'élève également une coLonnette 23 s'étendant parallèlement à l'axe _ en étant décalée radialement par rapport à ce dernier. La coLonnette 23 supporte, sur un étage superposé à ceux des paires de tiges, une tige filetée 24 occupant une direction orthogonale à celles des paires de tiges. La tige 24 peut être commandée en rotation par un bouton 25 et porte un curseur taraudé 26. Le support 17 comporte, par ailleurs, un index 27 destiné à coopérer avec une échelle graduée 28 présentée par le berceau 10 et possédant une plage de graduations marquée de part et d'autre d'une position zéro.The sole 1 is mounted on a sole holder by means of an anti-rotation lug and a fixing means 2. The sole holder is articulated on a first support 3, constituted by a plate, by means of a lockable axis 4 materializing the geometric axis A-A '. The plate 3 is mounted by a pivot 5, materializing the geometric axis CC, on a second support 6 constituted by a lifting beam extending perpendicular to the plane of the plate. The lifting beam 6 is mounted on an arm 7 by an axis 8 materializing the geometric axis BB "of supination-pronation. The arm 7 is mounted telescopically adjustable in a tubular frame 9 common to the two arms and extending parallel to the axes A- The frame 9 is carried by a cradle 10 mounted by two coaxial pivots 11 on a console 12 carried by a bracket 13 forming part of a mounting structure comprising a support base or a suspension member. materialize a geometric pivot axis ^ parallel to the axes AA 'and situated between the latter and the frame 9. The cradle 10 supports an actuation system in concomitant alternating partial angular pivotings of the assemblies Ia_ and Ib. The actuation system comprises a drive member capable of being driven in alternating partial angular rotations This drive member is constituted by an electric motor 14 with two directions of rotation, associated with a potential ometer or even an angular position encoder. The motor 14 is mounted on the cradle 10 and carries, by its output shaft, a toothed pinion 15 permanently meshing with a toothed wheel 16 rotating on an axis Y_ and with which it forms a reduction gear. The actuation system also includes a device for transforming the movement of the partial angular rotation of the motor member into a straight line reciprocating movement. This transformation device consists of a support 17 integral with the wheel 16 and on which are mounted, in two superposed stages, two pairs 18a-18b and 19a-19b of rods at least partly threaded and capable of being controlled by rotation each by a button 20. The rods 18a-18b and 19a-19b extend parallel to each other, on either side of the axis y_ being also arranged on either side of said axis in each pair. The rods 18a-18b and 19a-19b each support a threaded slider 21jî-21fc) and 22a-22b whose axial position can be adjusted by rotation of the corresponding rod by means of the knob 20. From the support 17 also rises a collar 23 extending parallel to the axis _ while being offset radially relative to the latter. The collar 23 supports, on a stage superimposed on those of the pairs of rods, a threaded rod 24 occupying a direction orthogonal to those of the pairs of rods. The rod 24 can be controlled in rotation by a button 25 and carries a threaded slider 26. The support 17 also includes an index 27 intended to cooperate with a graduated scale 28 presented by the cradle 10 and having a marked range of graduations on either side of a zero position.
Les curseurs ^a_ et 21J) sont initialement montés sur Les tiges 18a et 18b, de manière à être situés en opposition de part et d'autre de l'axe J(. Les curseurs 21_a et 21Ja sont Liés par des articulations 30_a-30b à des biellettes 31 ι-31b adaptées par des noix de réglages 32a et 32b sur Les palonniers 6^ et 6b. Une disposition inversement symétrique est adoptée pour La position des curseurs 22a et 22b sur les tiges 19ιa et 19b. Les curseurs 22a et 22b sont liés par des articulations 33a et 33b à des biellettes 34a et 34b qui sont adaptées par des noix de réglage 35a et 35b sur des prolongements 36^ et 36b solidaires des platines 3_a et 3b. Le curseur 26 est Lié par une articulation 37 à une biellette 38 adaptée, par une noix articulée de réglage 39, sur la console 12. L'appareil décrit ci-dessus fonctionne de La façon suivante.The cursors ^ a_ and 21J) are initially mounted on the rods 18a and 18b, so as to be situated in opposition on either side of the axis J (. The cursors 21_a and 21Ja are linked by articulations 30_a-30b to rods 31 ι-31b adapted by adjustment nuts 32a and 32b on the spreaders 6 ^ and 6b. An inversely symmetrical arrangement is adopted for the position of the sliders 22a and 22b on the rods 19ιa and 19b. The sliders 22a and 22b are linked by joints 33a and 33b to links 34a and 34b which are adapted by adjusting nuts 35a and 35b on extensions 36 ^ and 36b integral with the plates 3_a and 3b. The cursor 26 is linked by an articulation 37 to a suitable link 38, by an articulated adjusting nut 39, on the console 12. The apparatus described above operates in the following manner.
Le sujet devant être mobilisé est présenté, comme illustré par la fig. 7, par exemple à plat dos, de manière à amener les pieds sur Les semelles 11 sur lesquelles iLs sont adaptés par bandage. Les différents curseurs 21 , 21J3 et 22a, 22b et 26 sont amenés en position radiale extrême, par L'intermédiaire des boutons 20, puis les noix correspondantes 32a, 32b et 35a, 35b et 39 sont débloquées. Les bras télescopiques 7 sont ensuite réglés en écarte ent relatif, de manière à placer les semelles 1 dans la position de présentation adaptée à la taille et à La morphologie du sujet. Les noix 32a, 32b, 35a, 35b et 39 sont alors bloquées.The subject to be mobilized is presented, as illustrated in fig. 7, for example flat back, so as to bring the feet on the soles 11 on which iLs are adapted by bandage. The different sliders 21, 21J3 and 22a, 22b and 26 are brought into the extreme radial position, by means of the buttons 20, then the corresponding nuts 32a, 32b and 35a, 35b and 39 are released. The telescopic arms 7 are then adjusted in relative spacing, so as to place the soles 1 in the presentation position adapted to the size and the morphology of the subject. The nuts 32a, 32b, 35a, 35b and 39 are then blocked.
L'adaptation ci-dessus, nécessaire en fonction du sujet à mobiliser, est effectuée dans une position neutre du système d'actionnement maintenant le boîtier 17 en référence d'alignement par son index 27 avec le zéro de l'échelle 28.The above adaptation, necessary according to the subject to be mobilized, is carried out in a neutral position of the actuation system maintaining the housing 17 in alignment reference by its index 27 with the zero of the scale 28.
Dans cet état, le moteur 14 peut être alimenté pour entraîner la rotation de la roue 16 dans le sens de La flèche f. (fig. 7) sur une amplitude angulaire maximale, par exemple égale à 45 . Cette rotation fait tourner le boîtier 17, ce qui produit, simultanément, les effets suivants : a) - Les biellettes 31a et 31b poussent les palonniers versIn this state, the motor 14 can be powered to drive the rotation of the wheel 16 in the direction of arrow f. (fig. 7) over a maximum angular amplitude, for example equal to 45. This rotation causes the housing 17 to rotate, which simultaneously produces the following effects: a) - The links 31a and 31b push the spreaders towards
L'extérieur par rapport au plan sagittal î. Les palonniers pivotent sur les axes B-B' dans le sens des flèches f? (fig. 11) entraînant les semelles Ta et 1> en supination. Les pieds du sujet sont, de cette manière, sollicités en varus sur un angle maximal de 45 . b) - Les biellettes 34a, 34b tirent vers l'intérieur par rapport au plan ^ les prolongements 36 et 36b qui font tourner les platines 3a, 3b sur les pivots 5 matérialisant les axes C-C. Les semelles la et Ib sont entraînées selon la flèche f, (fig. 12 et 12a) en abduction sur une valeur angulaire maximale de 45 . c) - La biellette 38, de longueur fixe, s'oppose à La rotation du boîtier 17, ce qui produit, en réaction, le pivotement du berceau 10 sur L'axe x-x* dans le sens de la flèche f^ (fig. 13). Les semelles 1 et Ib sont déplacées simultanément vers Le bas et sollicitent les pieds en flexion dorsale sur une amplitude angulaire maximale de 40 . Les curseurs 21ja, 21b, 22a, 22b et 26 peuvent être réglés jusqu'en position radiale interne, de manière à faire varier L'amplitude angulaire en supination (varus), abduction et flexion, d'une valeur maximale à une valeur nulle, comme cela est illustré par la fig. 14 pour la supination, par les fig. 15 et 15 pour l'abduction et par La fig. 16 pour La flexion.The exterior relative to the sagittal plane î. The spreaders rotate on the axes BB 'in the direction of the arrows f ? ( fig. 11) driving the soles Ta and 1> in supination. The feet of the subject are, in this way, solicited in varus on a maximum angle of 45. b) - The links 34a, 34b pull inwards relative to the plane ^ the extensions 36 and 36b which rotate the plates 3a, 3b on the pivots 5 materializing the axes CC. The flanges la and Ib are driven along the arrow f, (fig. 12 and 12a) in abduction on a maximum angular value of 45. c) - The rod 38, of fixed length, opposes the rotation of the housing 17, which produces, in reaction, the pivoting of the cradle 10 on the axis xx * in the direction of the arrow f ^ (fig. 13). The soles 1 and Ib are moved simultaneously downwards and stress the feet in dorsal flexion over a maximum angular amplitude of 40. The sliders 21ja, 21b, 22a, 22b and 26 can be adjusted to the internal radial position, so as to vary the angular amplitude in supination (varus), abduction and flexion, from a maximum value to a zero value, as illustrated in fig. 14 for supination, by figs. 15 and 15 for abduction and by fig. 16 for Bending.
Des mouvements inverses à ceux ci-dessus, sollicitant les pieds en pronation (valgus), en adduction et en flexion plantaire, interviennent dès que l'alimentation du moteur 14 est inversée pour faire tourner la roue 16 dans le sens opposé à celui de la flèche fy et ramener le boîtier 17 dans La position neutre selon la fig. 7.Reverse movements to those above, urging the feet in pronation (valgus), in adduction and plantar flexion, occur as soon as the power supply to the motor 14 is reversed to rotate the wheel 16 in the opposite direction to that of the arrow fy and return the box 17 to the neutral position according to fig. 7.
IL est à noter qu'il est possible de régler, indépendamment, les trois mouvements dans le respect des possibilités physiologiques et anatomiques des articulations du pied, en agissant séparément sur les boutons 20, de manière à régler la position des curseurs 21, 22 et 26. IL est, également, possible de débloquer L'axe 4 de chaque semelle 1 lorsqu'il est souhaité retrouver une liberté de pivotement sur L'axe A-A'.It should be noted that it is possible to adjust, independently, the three movements while respecting the physiological and anatomical possibilities of the joints of the foot, by acting separately on the buttons 20, so as to adjust the position of the sliders 21, 22 and 26. It is also possible to unlock the axis 4 of each sole 1 when it is desired to find freedom of pivoting on the axis A-A '.
Les fig. 17 et 18 montrent une variante consistant à ne monter, sur Le boîtier 17, que Le système d'actionnement pour un seul ensemble de mobilisation, par exemple L'ensemble Ib selon La fig. 17 pour La mobilisation du pied gauche. Dans un tel cas, le pied droit peut être adapté sur un ensemble statique I.. comprenant une semeLle fixe 1.. montée sur un bras immobile 7. directement porté par La console 12. Une variante de construction structurelle est illustrée par la fig. 18 correspondant à La mobilisation du pied droit. De cette manière, une mobilisation d'un seul pied peut intervenir avec immobilisation du second dans une posture d'ensemble respectant la symétrie et supprimant toute mobilisation naturelle désordonnée que l'enfant pourrait adopter pour le pied libre.Figs. 17 and 18 show a variant consisting in mounting, on the housing 17, only the actuation system for a single mobilization assembly, for example the assembly Ib according to FIG. 17 for Mobilization of the left foot. In such a case, the right foot can be adapted to a static assembly I .. comprising a fixed base 1 .. mounted on a stationary arm 7. directly carried by the console 12. A variant of structural construction is illustrated in fig. 18 corresponding to the mobilization of the right foot. In this way, a mobilization of one foot can occur with immobilization of the second in an overall posture respecting symmetry and eliminating any disorderly natural mobilization that the child could adopt for the free foot.
La fig. 10 montre qu'il peut être avantageux d'interposer, entre La potence 13 et une embase 40 éventuelle une articulation crantée 41 permettant de régler la position de référence de la console 12.Fig. 10 shows that it may be advantageous to interpose, between the bracket 13 and a possible base 40, a notched articulation 41 making it possible to adjust the reference position of the console 12.
