Description

La présente invention concerne un nouvel appareil d'échographie simplifié. En effet, il est préconçu<U>uniquement</U> pour l'exploration d'articulations Temporo-Mandibulaires (ATM) dans le cas d'examens stomatologiques. The present invention relates to a novel simplified ultrasound apparatus. Indeed, it is preconceived <U> only </ U> for the exploration of Temporo-mandibular joints (ATM) in the case of stomatological examinations.

Pour y parvenir, tous les différents paramètres nécessaires à la visualisation de la région examinée ont été déjà préétablis et réglés lors de sa conception industrielle. To achieve this, all the different parameters needed to visualize the region examined have already been pre-established and adjusted during its industrial design.

Les appareils d'échographie classiques sont en effet très élaborés en raison de la possibilité qui est offerte pour le réglage des différents paramètres de visualisation selon la région anatomique à observer, ce qui nécessite l'élaboration d'un système de réglage, impliquant une augmentation considérable de la taille et du coût de l'appareil. Ceci ne sera pas le cas de l'appareil proposé plus haut, puisqu'il est destiné uniquement à l'examen d'ATM et par conséquent ne nécessite aucun réglage. The conventional ultrasound machines are indeed very elaborate because of the possibility that is offered for the adjustment of the different visualization parameters according to the anatomical region to be observed, which requires the development of a control system, involving an increase considerable size and cost of the device. This will not be the case of the device proposed above, since it is intended solely for ATM examination and therefore does not require any adjustment.

Ainsi, nous disposerons d'un appareil de faible dimension et moins onéreux ce qui permettra la généralisation de son application dans les cabinets médicaux, notamment sur le plan financier. L'appareil permet d'obtenir directement et instantanément les images de l'ATM en repos<U>mais surtout lors de leur mouvement</U>. Thus, we will have a small and less expensive device which will allow the generalization of its application in medical practices, especially in financial terms. The device allows to obtain directly and instantly images of the ATM at rest <U> but especially during their movement </ U>.

L'examen d'ATM par imagerie médicale conventionnelle: par exemple la radiographie panoramique (orthopantomogramme) ne permet pas la visualisation de cette double articulation en<U>mouvement</U>. Ce qui est un handicap dans l'examen de pathologie articulaire. De plus, le coût d'un appareil d'orthopantomogramme est considérable et ne permet pas de généraliser son usage dans les cabinets médicaux.  The examination of ATM by conventional medical imaging: for example panoramic radiography (orthopantomogram) does not allow the visualization of this double articulation in <U> movement </ U>. Which is a handicap in the examination of articular pathology. In addition, the cost of an orthopantomogram device is considerable and does not allow to generalize its use in medical practices.

La ciné IRM (examen par Résonance Magnétique Nucléaire) permet de visualiser les organes en<U>mouvement</U> comme en échographie. Mais dû à son coût élevé, seuls certains hôpitaux spécialisés pourront<U>uniquement</U> être équipés de cet appareil. The MRI (Nuclear Magnetic Resonance Examination) film is used to visualize organs in <U> movement </ U> as in ultrasound. But due to its high cost, only some specialized hospitals can <U> only </ U> be equipped with this device.

Les autres imageries médicales ne permettent aucun examen d'ATM en mouvement. Il s'agit de # La radiographie tomographique ; # L'arthrographie ; # La tomodensitométrie (standard et tridimensionnelle) ; L' IRM ; A part l'IRM et la ciné IRM , les autres imageries font appel au rayon X (rayonnement ionisant) ce qui n'est pas le cas d'un examen d'échographie. Ce point est essentiel car il permet la répétition d'examen d'ATM pour mieux étudier la topographie de la région dans les différents mouvements mandibulaires (examen fonctionnel d'ATM), sans aucun inconvénient pour le patient, notamment pour les femmes enceintes qui ne doivent pas être exposées au rayon X. <U>Description de</U> l'appareil L'appareil est composé de 3 éléments 1.<U>Une double sonde</U> ultrasonique (droite et gauche) (Fig.l, n 1) envoyant des ondes de choc moléculaire à haute fréquence (faible longueur d'onde). II s'agit d'ondes acoustiques non perceptibles à l'oreille, comme pour les appareils d'échographie classiques mais pré-réglées uniquement pour la région d'articulations Temporo- Mandibulaires (ATM) ; La double sonde est obligatoire car la mandibule présente une double articulation (ATM droite et ATM gauche) ; 2.<U>Un appui semi-circulaire</U> (Fig.l, n 2) sur lequel sont fixées les deux sondes. Il se place autour de la nuque du patient et il est flexible. Les sondes s'articulent sur cet appui à leur jonction en y formant un plan perpendiculaire. Elles se placent en avant des deux conduites auditives externes en gardant un contact cutané. Elles sont réglables en hauteur et doivent alors être télescopiques ; 3.<U>Un écran</U> (Fig.2, <I>n 3)</I> qui permet de visualiser simultanément les ATM droite et gauche et de les comparer. Cet écran, de taille réduite, est lié à l'appui semi-circulaire par un fil électrique et se pose sur la table du travail. Il est muni d'une mémoire volatile qui permet d'enregistrer sélectivement une image. L'écran est connecté à une imprimante (Fig.2, n 4) qui permet de reproduire sur papier l'image enregistrée<B>;</B> Principe <U>d'exploitation de la région à étudier</U> Il s'agit d'un appareil d'échographie bi-dimensionnelle (échotomographie) à l'opposition d'une échographie unidimensionnelle (très peu utilisée car elle ne montre les structures rencontrées par le faisceau d'utilisation, que le long d'une ligne droite). Other medical imaging does not allow any moving ATM exams. This is # Tomographic X-ray; # Arthrography; # Computed tomography (standard and three-dimensional); MRI; Apart from MRI and Cine MRI, the other imaging uses X-ray (ionizing radiation) which is not the case of an ultrasound examination. This point is essential because it allows the ATM examination repetition to better study the topography of the region in the different mandibular movements (ATM functional examination), without any inconvenience for the patient, especially for pregnant women who do not must not be exposed to the X-ray. <U> Description of </ U> the device The device is composed of 3 elements 1. <U> An ultrasonic double probe </ U> (right and left) (Fig.l , n 1) sending high frequency (low wavelength) molecular shock waves. These are acoustic waves not perceptible to the ear, as for conventional ultrasound machines but pre-set only for the region of temporomandibular joints (TMJ); The double probe is mandatory because the mandible has a double joint (right ATM and left ATM); 2. <U> A semicircular support </ U> (Fig.l, n 2) on which are fixed the two probes. It is placed around the patient's neck and is flexible. The probes are articulated on this support at their junction forming a perpendicular plane. They are placed in front of the two external auditory conduits while keeping skin contact. They are adjustable in height and must be telescopic; 3. <U> A </ U> screen (Fig.2, <I> n 3) </ I> that allows you to view the right and left ATMs simultaneously and compare them. This screen, reduced in size, is connected to the semicircular support by a wire and is placed on the work table. It is equipped with a volatile memory which makes it possible to selectively record an image. The screen is connected to a printer (Fig.2, n 4) which allows to reproduce on paper the recorded image <B> </ B> Principle <U> of exploitation of the region to study </ U> It is a two-dimensional ultrasound machine (echotomography) opposed to a one-dimensional ultrasound (very little used because it shows the structures encountered by the beam of use, that along a straight line).

Les deux sondes sont munies d'un émetteur d'ultrason (ondes acoustiques non perçus par l'oreille humaine). Les ondes réfléchies (principe du radar) sont transformées ensuite en signaux électroniques afin de visualiser la région concernée (principe des appareils classiques d'échographie bi-dimensionnelle). Pour favoriser la transmission des ondes ultrasons dans la région anatomique à étudier, les surfaces (zones cutanées) seront préalablement enduites d'un gel (principe d'échographie externe). Both probes are equipped with an ultrasound emitter (acoustic waves not perceived by the human ear). The reflected waves (radar principle) are then transformed into electronic signals to visualize the region concerned (principle of conventional two-dimensional ultrasound devices). To promote the transmission of ultrasound waves in the anatomical region to be studied, the surfaces (cutaneous zones) will be previously coated with a gel (external ultrasound principle).

Le dispositif selon l'invention est destiné uniquement à explorer les articulations Temporo- Mandibulaires droite et gauche.The device according to the invention is intended solely for exploring the right and left temporomandibular joints.
