SYSTEME DE RADIOLOGIE TELECOMMANDE EQUIPE D’UN DISPOSITIF REMOTE CONTROL RADIOLOGY SYSTEM PROVIDED WITH A DEVICE
DE COMPRESSION COMPRESSION
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention se rapporte au domaine technique des dispositifs médicaux destinés à la réalisation d’actes d’imagerie médicale, et concerne plus particulièrement un système de radiologie télécommandé équipé d’un dispositif de compression d’une partie du corps d’un patient, limitant l’épaisseur traversée par les rayons X émis par un élément radiogène. The present invention relates to the technical field of medical devices intended for performing medical imaging procedures, and more particularly relates to a remote-controlled radiology system equipped with a device for compressing a part of the body of a patient, limiting the thickness traversed by the X-rays emitted by an X-ray element.
ART ANTERIEUR PRIOR ART
Dans le domaine des dispositifs médicaux destinés à la réalisation d’actes d’imagerie médicale, on connaît, par exemple, une table de radiologie télécommandée comprenant. In the field of medical devices intended for performing medical imaging procedures, there is known, for example, a remote-controlled radiology table comprising.
- une colonne porte-tube à rayons X, mobile en translation le long et à l’arrière de la table ; - an X-ray tube-holder column, movable in translation along and behind the table;
- un récepteur de rayons X disposé sous la table et, par exemple solidaire de la colonne pour se déplacer en fonction de la position du tube à rayons X ou de l’élément radiogène ; - an X-ray receiver placed under the table and, for example secured to the column to move according to the position of the X-ray tube or the X-ray element;
- un dispositif de compression escamotable, fixé sur la colonne et centré sur les rayons X émis par l’élément radiogène, par exemple en incidence normale lors d’un examen radiographique d’une partie du corps d’un patient. - a retractable compression device, fixed on the column and centered on the X-rays emitted by the radiogenic element, for example at normal incidence during an radiographic examination of a part of the body of a patient.
Le dispositif de compression d’une partie du corps du patient, par exemple, l’abdomen, permet de limiter l’épaisseur traversée par les rayons X émis par l’élément radiogène pour améliorer le contraste et donc la qualité de l’image radiographique. A cet effet, le dispositif est apte à se déplacer le long de la colonne pour réaliser la compression sur la partie du corps du patient. The device for compressing a part of the patient's body, for example the abdomen, makes it possible to limit the thickness traversed by the X-rays emitted by the radiogenic element to improve the contrast and therefore the quality of the radiographic image. . For this purpose, the device is able to move along the column to achieve compression on the part of the patient's body.
L’inconvénient de cette table de radiologie télécommandée est le fait qu’elle doit intégrer des éléments mécaniques, tel qu’un moteur par exemple, pour assurer le dép lacement du dispositif de compression le long de la colonne, et permettre la compression. L’ajout de ces éléments complexifie donc la conception globale de la table et particulièrement celle de la colonne engendrant par ailleurs une augmentation des coûts de production. Aussi, le dispositif de compression fixé sur la colonne limite les possibilités de modification de cette dernière. The disadvantage of this remote-controlled radiology table is the fact that it must integrate mechanical elements, such as a motor for example, to ensure the displacement of the compression device along the column, and allow compression. The addition of these elements therefore complicates the overall design of the table and particularly that of the column, furthermore generating an increase in production costs. Also, the compression device fixed on the column limits the possibilities of modification of the latter.
Un autre inconvénient de cet état de la technique système est que le dispositif de compression ne permet pas de changer de dispositif de compression en fonction de la morphologie du patient. Another disadvantage of this state of the art system is that the compression device does not allow to change the compression device depending on the morphology of the patient.
On connaît également des systèmes de radiologie télécommandés avec bras porte- tube à rayons X fixé au plafond. L’inconvénient inhérent à ce type de système est qu’il ne possède pas, sans présence de colonne fixée à la table, de dispositif de compression. There are also known remote control radiology systems with X-ray tube-holder arms fixed to the ceiling. The drawback inherent in this type of system is that it does not have, without the presence of a column fixed to the table, a compression device.
EXPOSE DE L’INVENTION STATEMENT OF THE INVENTION
L’un des buts de l’invention est donc de remédier aux inconvénients de l’art antérieur en proposant une table de radiologie qui soit plus simple, notamment dans l’intégration et l’utilisation d’un système de compression. One of the aims of the invention is therefore to remedy the drawbacks of the prior art by proposing a radiology table which is simpler, in particular in the integration and use of a compression system.
A cet effet, il a été mis au point une table de radiologie télécommandée conforme à l’état de la technique en ce qu’elle comprend une table apte à recevoir un patient, un récepteur de rayons X installé sous la table, et un élément radiogène apte à émettre des rayons X situé au-dessus de la table et apte à se déplacer relativement par rapport à la table et en direction de celle-ci pour un réglage de la distance focale et, par exemple de l’angle d’incidence de l’élément radiogène. To this end, a remote-controlled radiology table conforming to the state of the art has been developed in that it comprises a table suitable for receiving a patient, an X-ray receiver installed under the table, and an element X-ray capable of emitting X-rays located above the table and able to move relatively with respect to and towards the table for adjustment of the focal distance and, for example of the angle of incidence of the X-ray element.
Selon l’invention, le système comprend un dispositif de compression d’une partie du corps du patient centré sur les rayons X et fixé, de préférence de manière amovible, sur l’élément radiogène de sorte que le déplacement relatif de l’élément radiogène en direction de la table permet la compression de la partie du corps du patient. De cette manière, l’invention permet de réaliser une compression d’une partie du corps du patient par un déplacement de la table en direction de l’élément radiogène ou par celui de l’élément radiogène vers la table. Le mouvement de compression est donc assuré par le réglage de la distance focale correspondant à la distance entre l’élément radiogène et le récepteur des rayons X. According to the invention, the system comprises a device for compressing a part of the patient's body centered on the X-rays and fixed, preferably removably, on the X-ray element so that the relative movement of the X-ray element towards the table allows compression of the patient's body part. In this way, the invention makes it possible to achieve compression of a part of the patient's body by a movement of the table in the direction of the radiogenic element or by that of the radiogenic element towards the table. The compression movement is therefore ensured by adjusting the focal length corresponding to the distance between the X-ray element and the X-ray receiver.
L’invention permet ainsi de simplifier le montage du dispositif de compression en facilitant l’intégration de ce dernier et en réduisant par ailleurs le coût de production de la table de radiologie télécommandée par l’absence de moteurs, de pièces mécaniques, etc. The invention thus makes it possible to simplify the mounting of the compression device by facilitating the integration of the latter and also reducing the production cost of the remote-controlled radiology table by the absence of motors, mechanical parts, etc.
Etant donné que le dispositif de compression n’est pas lié mécaniquement directement à la colonne, l’invention permet de faire varier facilement et sans incidence la conception de la colonne. Since the compression device is not mechanically linked directly to the column, the invention makes it possible to vary the design of the column easily and without incidence.
De ce qui précède, il est également possible de modifier les tables de l’art antérieur pour y fixer le dispositif de compression sur l’élément radiogène. From the above, it is also possible to modify the tables of the prior art to fix the compression device on the X-ray element.
Avantageusement et afin de limiter l’encombrement, le dispositif de compression est articulé de manière à pouvoir se replier, soit manuellement, soit automatiquement par un utilisateur du système via, par exemple, un pupitre de commande. Le dispositif de compression peut alors, par exemple, être rangé efficacement dans un logement situé sur l’élément radiogène et prévu à cet effet, ou alors être replié sur au moins un côté de l’élément radiogène. Advantageously and in order to limit the space requirement, the compression device is articulated so as to be able to fold, either manually or automatically by a user of the system via, for example, a control console. The compression device can then, for example, be efficiently stored in a housing located on the X-ray element and provided for this purpose, or else be folded over at least one side of the X-ray element.
Selon une forme de réalisation particulière, le dispositif de compression est, par exemple, une louche comprenant un manche dont l’extrémité opposée à la louche dispose d’un moyen de fixation à l’élément radiogène. According to a particular embodiment, the compression device is, for example, a ladle comprising a handle whose end opposite the ladle has a means of attachment to the radiogenic element.
Pour assurer l’amovibilité, le moyen de fixation est, par exemple, un insert mâle destiné à être introduit dans un logement complémentaire femelle situé sur l’élément radiogène. De préférence, le manche du dispositif de compression est courbé permettant à la louche d’être centrée sur les rayons X émis par l’élément radiogène, sans que ce manche ne vienne gêner lui-même les rayons X. To ensure the removability, the fixing means is, for example, a male insert intended to be introduced into a complementary female housing located on the radiogenic element. Preferably, the handle of the compression device is curved allowing the ladle to be centered on the X-rays emitted by the X-ray element, without this handle itself interfering with the X-rays.
Avantageusement, le manche du dispositif est télescopique permettant de régler l’allongement du dispositif de compression, et de s’adapter à la focale de l’élément radiogène. Advantageously, the handle of the device is telescopic making it possible to adjust the elongation of the compression device, and to adapt to the focal length of the radiogenic element.

DESCRIPTION DETAILLEE DE L’INVENTION DETAILED DESCRIPTION OF THE INVENTION
En référence aux figures 1 à 4, l’invention concerne un système (A) de radiologie télécommandé équipé d’un dispositif de compression (4) centré sur les rayons X et fixé sur l’élément radiogène (3). With reference to FIGS. 1 to 4, the invention relates to a remote-controlled radiology system (A) equipped with a compression device (4) centered on the X-rays and fixed on the radiogenic element (3).
Plus particulièrement, le système (A) comprend une table (1) apte à recevoir un patient en position allongée, un récepteur de rayons X (2) installé sous la table (1) et un élément radiogène (3) situé au-dessus de la table (1) apte à émettre des rayons X et à se dép lacer relativement par rapport à la table (1) pour régler la distance focale correspondant à la distance entre l’élément radiogène (3) et le récepteur de rayons X (2) et, par exemple l’angle d’incidence (±10°) des rayons X émis par l’élément radiogène (3). More particularly, the system (A) comprises a table (1) capable of receiving a patient in the lying position, an X-ray receiver (2) installed under the table (1) and an X-ray element (3) located above the table (1) capable of emitting X-rays and place relatively in relation to the table (1) to adjust the focal distance corresponding to the distance between the X-ray element (3) and the X-ray receiver (2) and, for example the angle of incidence (± 10 °) X-rays emitted by the radiogenic element (3).
En référence à la figure 4, le dispositif de compression (4) d’une partie du corps d’un patient est sous la forme, par exemple, d’une louche (5) ou d’une pelle comprenant un manche (6) dont l’extrémité opposée à la louche est fixée sur l’élément radiogène (3). Referring to Figure 4, the compression device (4) of a part of the body of a patient is in the form, for example, of a ladle (5) or a shovel comprising a handle (6) whose end opposite to the ladle is fixed on the radiogenic element (3).
Avantageusement, le manche (6) du dispositif de compression (4) est articulé pour être replié sur un côté de l’élément radiogène (3) et ainsi faciliter la manipulation et réduire l’encombrement après utilisation ou non du dispositif de compression (4). Advantageously, the handle (6) of the compression device (4) is articulated to be folded over on one side of the X-ray element (3) and thus facilitate handling and reduce the bulk after use or not of the compression device (4 ).
De préférence, l’articulation du manche (6) du dispositif de compression (4) est motorisée pour être replié automatiquement par un utilisateur du système (A) via, par exemple, un pupitre de commande (non représenté sur les figures). Preferably, the articulation of the handle (6) of the compression device (4) is motorized to be folded automatically by a user of the system (A) via, for example, a control console (not shown in the figures).
De préférence encore, le manche (6) du dispositif de compression (4) est monté amovible sur l’élément radiogène (3). Pour cela, l’extrémité supérieure du manche (6) dispose d’un moyen de fixation (7), par exemple, un insert mâle, destiné à être introduit dans un logement complémentaire femelle (8) situé sur l’élément radiogène (3). Cette amovibilité permet entre autre de libérer l’espace autour de l’élément radiogène (3), de n’utiliser le dispositif de compression (4) qu’en cas de stricte nécessité ou de changer de dispositif de compression (4) pour l’adapter à la morphologie du patient. More preferably, the handle (6) of the compression device (4) is removably mounted on the X-ray element (3). For this, the upper end of the handle (6) has a fixing means (7), for example, a male insert, intended to be introduced into a complementary female housing (8) located on the radiogenic element (3 ). This removability makes it possible, among other things, to free up the space around the radiogenic element (3), to use the compression device (4) only in case of strict necessity or to change the compression device (4) for the '' adapt to the patient's morphology.
De plus, le manche (6) du dispositif de compression (4) fixé sur une partie latérale de l’élément radiogène (3) est courbé pour positionner la louche (5) entre l’élément radiogène (3) et le patient. La louche (5) est alors centrée sur les rayons X émis par l’élément radiogène (3) sans que le manche (6) ne vienne gêner lui-même les rayons X. La louche (5), semi-sphérique et creuse, est également conçue pour ne pas gêner les rayons X émis par l’élément radiogène (3). In addition, the handle (6) of the compression device (4) fixed on a lateral part of the X-ray element (3) is curved to position the ladle (5) between the X-ray element (3) and the patient. The ladle (5) is then centered on the X-rays emitted by the radiogenic element (3) without the handle (6) itself interfering with the X-rays. The ladle (5), semi-spherical and hollow, is also designed not to obstruct the X-rays emitted by the radiogenic element (3).
Le mouvement de compression du dispositif de compression (4) est assuré par le réglage de la distance focale correspondant à la distance entre l’élément radiogène (3) et le récepteur de rayons X (2). Cette distance focale peut être ainsi réglée soit par le déplacement de l’élément radiogène (3), soit par le déplacement de la table (1) soit des deux. Avantageusement, le manche (6) du dispositif de compression (4) est télescopique.The compression movement of the compression device (4) is ensured by adjusting the focal distance corresponding to the distance between the X-ray element (3) and the X-ray receiver (2). This focal distance can thus be adjusted either by moving the X-ray element (3), or by moving the table (1) or both. Advantageously, the handle (6) of the compression device (4) is telescopic.
Le manche (6) peut alors s’allonger ou se rétracter pour s’adapter à la distance focale de l’élément radiogène (3). The handle (6) can then be extended or retracted to adapt to the focal distance of the X-ray element (3).
Lors de la compression d’une partie du corps du patient par le dispositif de compression (4), la louche (5), semi-sphérique, est également conçue pour assurer un bon contact avec une partie molle du corps du patient, par exemple, l’abdomen. L’étalement ou la compression de la partie du corps du patient par la louche (5) du dispositif de compression (4) réduit ainsi l’épaisseur traversée par les rayons X et améliore la qualité de l’image radiographique. En effet, en réduisant par compression le volume diffusant de la partie du corps examinée, la réduction du rayonnement diffusé, améliore le contraste de l’image. When compressing a part of the patient's body by the compression device (4), the ladle (5), semi-spherical, is also designed to ensure good contact with a soft part of the patient's body, for example , the abdomen. The spreading or compression of the patient's body part by the ladle (5) of the compression device (4) thus reduces the thickness traversed by the X-rays and improves the quality of the radiographic image. Indeed, by reducing by compression the diffusing volume of the part of the body examined, the reduction of the scattered radiation, improves the contrast of the image.
Il ressort de ce qui précède que l’invention fournit bien un système (A) de radiologie télécommandé équipé d’un dispositif de compression facile à intégrer et à replier autour de l’ensemble radiogène. Ce dispositif est également simple à utiliser pour un examen radiographique du patient. En somme, ces avantages de conception du dispositif de compression réduisent le coût global du système (A) et permettent d’être libre dans la conception de la colonne car il n’est pas directement monté sur cette dernière. It appears from the above that the invention does indeed provide a remote-controlled radiology system (A) equipped with a compression device that is easy to integrate and fold around the radiogenic assembly. This device is also simple to use for an X-ray examination of the patient. In sum, these design advantages of the compression device reduce the overall cost of the system (A) and allow freedom in the design of the column because it is not directly mounted on the latter.
