Abstract

A clamp (10) positioned on the canal to be closed can be opened using a solenoid (2) attracting one of its branches (4), the energy necessary for its operation, transmitted through wires (75), being produced by an energy sensor (7) placed in the body and capable, on the one hand, of picking up a wave capable of transporting energy coming from the outside, and, on the other hand, converting it into useful energy.

Description

La présente invention a pour objet un sphincter artificiel, notamment urinaire, destiné à accomplir une fonction du corps humain. The present invention relates to an artificial sphincter, in particular urinary, intended to perform a function of the human body.

On sait que certaines personnes connaissent des altérations ou des pertes de contrôle de leurs sphincters. We know that some people experience alterations or loss of control of their sphincters.

Pour remédier à ces déficiences, on a déjà proposé un dispositif hydraulique, ou pneumatique, constitué d'un ballonnet inséré chirurgicalement dans le corps, bloquant en permanence le canal présentant une défection, l'ouverture dudit canal s'effectuant par compression dudit ballonnet à l'aide d'une poire extérieure. To remedy these shortcomings, a hydraulic or pneumatic device has already been proposed, consisting of a balloon inserted surgically into the body, permanently blocking the defected channel, the opening of said channel being effected by compression of said balloon. using an outdoor pear.

Ce type de dispositif présente toutefois des inconvénients, d'une part esthétiques du fait de la presence de la poire, d'autre part de difficulté de pose, et d'autre part encore de fréquents disfonctionnements de la commande. However, this type of device has drawbacks, on the one hand aesthetic due to the presence of the pear, on the other hand of difficulty of installation, and on the other hand still frequent malfunctions of the control.

La présente invention vise à remédier à ces inconvénients en proposant un sphincter artificiel dont l'énergie nécessaire à son fonctionnement est produite extérieurement à l'organisme. The present invention aims to remedy these drawbacks by proposing an artificial sphincter whose energy necessary for its operation is produced outside the body.

Le sphincter artificiel objet de la présente invention comporte une pince positionnée soit sur un tuyau en matière plastique raccordant les deux extrémités du canal à obstruer soit sur le canal lui-même. The artificial sphincter object of the present invention comprises a clamp positioned either on a plastic pipe connecting the two ends of the channel to be obstructed or on the channel itself.

Cette pince est, au repos, fermée sur le tuyau ou le canal, et son ouverture est realisee électromagnétiquement au moyen d'un solénoïde dont l'énergie est fournie par un capteur d'anergie également interne à l'organisme. This clamp is, at rest, closed on the pipe or the channel, and its opening is made electromagnetically by means of a solenoid whose energy is supplied by an anergy sensor also internal to the organism.

Le capteur d'énergie réceptionne et convertit des ondes provenant de l'extérieur de l'organisme et traversant la peau, en une énergie électrique qu'il transmet au solénoïde, ces ondes pouvant être magnétiques ou électromagnétiques (B.F., H.F., U.H.F., micro-ondes, radar) ou consister en toute autre onde susceptible de transporter de l'énergie. The energy sensor receives and converts waves coming from outside the body and passing through the skin, into electrical energy which it transmits to the solenoid, these waves can be magnetic or electromagnetic (BF, HF, UHF, micro -waves, radar) or consist of any other wave capable of transporting energy.

A cet effet le capteur d'énergie comporte une antenne, un condensateur ajustable et un ensemble de redressement ou tout autre dispositif de réception de 1 'énergie externe.  To this end, the energy sensor comprises an antenna, an adjustable capacitor and a rectification assembly or any other device for receiving external energy.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé:
- la figure 1 représente une vue partielle, de profil, d'un sphincter artificiel selon l'invention relié à un capteur d'énergie représenté schématiquement.In the attached drawing:
- Figure 1 shows a partial view, in profile, of an artificial sphincter according to the invention connected to an energy sensor shown diagrammatically.

- la figure 2 représente une vue de dessus de ces mêmes sphincter et capteur d'énergie. - Figure 2 shows a top view of these same sphincter and energy sensor.

Si on se réfère aux figures 1 et 2 on peut voir que le sphincter artificiel selon l'invention comporte une embase 1 de fixation corporelle, percée à cet effet d'orifices 15, sur laquelle est fixée un solenoïde 2. If one refers to FIGS. 1 and 2, it can be seen that the artificial sphincter according to the invention comprises a base 1 for body fixing, pierced for this purpose with orifices 15, on which a solenoid 2 is fixed.

Sur l'embase 1 est solidarisée une structure 3 en fil inox cintré symétriquement de manière d'une part que ses extrémités 30 et 31 soient de part et d'autre, au-dessus et en arrière du solénoïde 2, et d'autre part que soit créé en avant et au-dessus du solénoïde 2 un rebord 32 dirigé vers ce dernier et sensiblement parallèle à l'embase 1. On the base 1 is secured a structure 3 in symmetrically bent stainless steel wire so that on the one hand its ends 30 and 31 are on either side, above and behind the solenoid 2, and on the other hand that a rim 32 directed towards the latter and substantially parallel to the base 1 be created in front of and above the solenoid 2.

Les extrémités 30 et 31 sont traversées par un axe 33 sur lequel peut pivoter une seconde structure 4 en fil inox cintré passant au-dessus du solénoïde 2 et dont la partie extrême 40 prend place sous le rebord 32 de la structure 3 et peut, au gré du pivotement, se rapprocher ou s'éloigner dudit rebord 32, la structure 3 et la structure 4 formant ainsi une pince 10. The ends 30 and 31 are crossed by an axis 33 on which a second structure 4 can be pivoted in bent stainless steel wire passing over the solenoid 2 and the end portion 40 of which takes place under the rim 32 of the structure 3 and can, at depending on the pivoting, approaching or moving away from said rim 32, the structure 3 and the structure 4 thus forming a clamp 10.

Sur l'embase 1 est également solidarisée, dans un plan vertical situé entre le solénoïde 2 et le plan vertical de l'axe 33, une plaque 11 à l'extrémité supérieure de laquelle peut pivoter, autour d'un axe 12 parallèle à l'axe 33 et situé dans un plan horizontal affleurant le bord supérieur du solénoïde 2, une plaque 13 s'intercalant entre le solénoïde 2 et la structure 4. On the base 1 is also secured, in a vertical plane located between the solenoid 2 and the vertical plane of the axis 33, a plate 11 at the upper end of which can pivot, about an axis 12 parallel to the axis 33 and situated in a horizontal plane flush with the upper edge of the solenoid 2, a plate 13 inserted between the solenoid 2 and the structure 4.

Cette plaque 13 est rappelée par un ressort 14 tendu entre son extrémité et l'embase 1, de manière à être maintenue écartee du solénoïde 2.  This plate 13 is recalled by a spring 14 stretched between its end and the base 1, so as to be kept apart from the solenoid 2.

Le solénoïde 2 et les plaques 11 et 13 sont isolés du milieu corporel par une poche en silicone 6 les englobant. The solenoid 2 and the plates 11 and 13 are isolated from the body medium by a silicone bag 6 encompassing them.

Le sphincter est placé dans le corps de manière que le canal 5 concerné passe entre les structures 3 et 4, sous le rebord 32. The sphincter is placed in the body so that the channel 5 concerned passes between the structures 3 and 4, under the flange 32.

Ainsi, lorsque le solénoïde 2 n'est pas alimenté en énergie électrique, la plaque 13 est soumise à l'action du ressort qui repousse vers le haut la structure 4 et le canal 5 se trouve comprimé entre le rebord 32 de la structure 3 et la partie extrême 40 de la structure 4. Thus, when the solenoid 2 is not supplied with electrical energy, the plate 13 is subjected to the action of the spring which pushes up the structure 4 and the channel 5 is compressed between the flange 32 of the structure 3 and the extreme part 40 of the structure 4.

Pour ouvrir le canal 5 il suffit d'alimenter le solénoïde 2, qui attire et maintient la plaque 13, la partie 40 de la structure 4 s'écartant alors du rebord 32 de la structure 3. To open the channel 5, it suffices to supply the solenoid 2, which attracts and maintains the plate 13, the part 40 of the structure 4 then moving away from the rim 32 of the structure 3.

Le capteur d'énergie 7 comporte une embase corporelle 70, une antenne, ou collecteur d'ondes, 71, un pont redresseur 72, et un dispositif 73 d'accord de l'onde produite par l'émetteur, l'ensemble étant isolé de l'organisme par une poche 74 en silicone. The energy sensor 7 comprises a body base 70, an antenna, or wave collector, 71, a rectifier bridge 72, and a device 73 for tuning the wave produced by the transmitter, the assembly being isolated. of the body by a silicone pocket 74.

Le capteur d'énergie 7 est relié au solénoïde 2 par l'intermédiaire de fils 75 passant dans un tube silicone 76. The energy sensor 7 is connected to the solenoid 2 via wires 75 passing through a silicone tube 76.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.  It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
