Description

Dispositif de liposuccion des graisses associé à un traitement de la peau par aspiration sous vide Fat liposuction device associated with a vacuum skin treatment
Domaine de l'inventionField of the invention
La présente invention a trait, en tant que produit industriel nouveau, à un dispositif associant la liposuccion des graisses à un traitement corporel par aspiration sous vide et éventuellement par un champ d'ultrasons. Art antérieurThe present invention relates, as a new industrial product, to a device associating liposuction of fats with a body treatment by vacuum suction and possibly by an ultrasound field. Prior art
On a souvent fait appel dans le passé à des techniques de liposuccion qui utilisent une canule aspirante sous-cutanée pour aspirer les graisses localisées sous la peau. Ces techniques ont parfois été combinées à un traitement des zones corporelles par un champ d'ultrasons à proximité des plaies de la peau percée par la canule.Liposuction techniques have often been used in the past, which use a subcutaneous suction cannula to aspirate fat located under the skin. These techniques have sometimes been combined with a treatment of the body areas by an ultrasound field near the wounds of the skin pierced by the cannula.
En particulier, de WO-A-92/09238 on connaît une technique de liposuccion selon laquelle (1°) on applique une sonde ultrasonique externe sur la peau et/ou insère une sonde ultrasonique interne sous la peau pour rompre ou détruire les cellules graisseuses et les tissus graisseux, puis (2°) aspire par l'intermédiaire d'une canule les cellules graisseuses et les tissus graisseux, ainsi rompus ou détruits, en l'absence d'un champ d'ultrasons.In particular, from WO-A-92/09238, a liposuction technique is known according to which (1 °) an external ultrasonic probe is applied to the skin and / or an internal ultrasonic probe is inserted under the skin to break or destroy the fat cells and the fatty tissues, then (2 °) sucks by means of a cannula the fatty cells and the fatty tissues, thus broken or destroyed, in the absence of an ultrasound field.
De FR-A-2 700 958 on connaît un dispositif de liposuccion comprenant une canule d'aspiration destinée à être introduite sous la peau et mise en vibration au moyen d'un organe vibratoire ultrasonique. Sous l'action des vibrations les graisses du tissu adipeux "fondent" ; elles sont ensuite aspirées à l'état "fondu".From FR-A-2 700 958 there is known a liposuction device comprising a suction cannula intended to be introduced under the skin and put into vibration by means of an ultrasonic vibrating member. Under the action of vibrations the fats of the adipose tissue "melt"; they are then aspirated in the "melted" state.
De EP-A-0 384 672 on connaît un dispositif de liposuccion insérable sous la peau et comprenant une canule solidaire d'un organe vibratoire ultrasonique. Sous l'action des vibrations les graisses du tissu adipeux sont dégradées et séparées du tissu musculaire sous-cutané. Ces graisses sont ensuite aspirées au moyen de la canule.EP-A-0 384 672 discloses a liposuction device insertable under the skin and comprising a cannula secured to an ultrasonic vibrating member. Under the action of vibrations the fats of the adipose tissue are degraded and separated from the subcutaneous muscle tissue. These fats are then aspirated by means of the cannula.
L'inconvénient majeur des dispositifs de liposuccion de FR-A-2 700 958 et EP-A-0 384 672 réside dans le fait que la canule soumise à des vibrations intervient en tant que scalpel chirurgical susceptible de provoquer des lésions ou coupures sous-cutanées. D'autre part, on connaît de la demande de brevet français N° 97 10 622, l'existence d'un traitement de la peau par des cycles comprenant chacun une phase d'aspiration sous vide de la peau et une phase d'exposition au champ d'ultrasons qui se superposent au moins partiellement, la phase d'aspiration sous vide débutant après ou en même temps que le début de la phase d'exposition au champ d'ultrasons.The major drawback of the liposuction devices of FR-A-2 700 958 and EP-A-0 384 672 lies in the fact that the cannula subjected to vibrations acts as a surgical scalpel capable of causing lesions or cuts under- skin. On the other hand, it is known from French patent application No. 97 10 622, the existence of a treatment of the skin by cycles each comprising a vacuum suction phase of the skin and an exposure phase to the ultrasound field which overlap at least partially, the vacuum suction phase starting after or at the same time as the start of the exposure phase to the ultrasound field.
En pratique, selon cette demande antérieure, l'aspiration sous vide est effectuée de façon à avoir dans l'enceinte close une pression inférieure à la pression atmosphérique ambiante, de préférence une pression comprise entre 10 et 10"1 Pa, et mieux une pression comprise entre 103 et 1In practice, according to this previous application, the vacuum suction is carried out so as to have in the closed enclosure a pressure less than ambient atmospheric pressure, preferably a pressure between 10 and 10 "1 Pa, and better a between 10 3 and 1
Pa.Pa.
Egalement en pratique, selon la dite demande antérieure, le champ d'ultrasons a une fréquence comprise entre 20 kHz et 100 MHz, de préférence une fréquence comprise entre 500 kHz et 50 MHz, et mieux une fréquence comprise entre 1 et 3 MHz.Also in practice, according to said prior application, the ultrasonic field has a frequency between 20 kHz and 100 MHz, preferably a frequency between 500 kHz and 50 MHz, and better still a frequency between 1 and 3 MHz.
Le but de ces traitements aux ultrasons et d'aspiration de la peau est d'améliorer la circulation sanguine et de favoriser la reconstitution des tissus au niveau des plaies. De plus, on a découvert de façon surprenante que l'exposition au champ d'ultrasons protège la portion de peau traitée vis- à-vis des effets indésirables bien connus de l'aspiration sous vide. L'un de ces effets indésirables peut être un inconvénient esthétique et psychologique de rougeurs persistantes sur les portions de peau traitées. On connaît également l'inconvénient physiologique qui résulte de l'éclatement possible des vaisseaux sanguins, ce qui est une source potentielle de formation de caillots de fibrine sous-cutanés.The purpose of these ultrasound and skin suction treatments is to improve blood circulation and promote the reconstitution of tissue in wounds. In addition, it has surprisingly been found that exposure to the ultrasonic field protects the portion of skin treated from the well-known undesirable effects of vacuum suction. One of these side effects can be an aesthetic and psychological disadvantage of persistent redness on the treated skin portions. We also know the physiological disadvantage which results from the possible bursting of blood vessels, which is a potential source of formation of subcutaneous fibrin clots.
Or, s'il est techniquement possible de réaliser à la fois une liposuccion et un traitement par aspiration sous vide et champs d'ultrasons, la multiplicité des dispositifs à utiliser, appareil de liposuccion, dispositif à ultrasons et d'aspiration de la peau, rend cette pratique contraignante et difficile, le prix de ces divers équipements étant également élevé. But de l'inventionHowever, if it is technically possible to carry out both liposuction and treatment by vacuum suction and ultrasound fields, the multiplicity of devices to be used, liposuction device, ultrasound device and skin suction device, makes this practice restrictive and difficult, the price of these various pieces of equipment also being high. Purpose of the invention
Le but de la présente invention est de proposer un dispositif de liposuccion simple et peu onéreux permettant également un traitement de la peau par aspiration sous vide et éventuellement par champ d'ultrasons. Objet de l'inventionThe object of the present invention is to provide a simple and inexpensive liposuction device also allowing treatment of the skin by vacuum suction and possibly by ultrasound field. Subject of the invention
Selon l'invention, on fournit une nouvelle solution technique pour résoudre le problème de la liposuccion avec traitement d'aspiration sous vide et éventuellement champ d'ultrasons. Selon cette nouvelle solution, on préconise un dispositif de liposuccion qui est caractérisé en ce qu'il comprend :According to the invention, a new technical solution is provided to solve the problem of liposuction with vacuum suction treatment and possibly an ultrasound field. According to this new solution, a liposuction device is recommended which is characterized in that it comprises:
- un moyen d'aspiration,- a means of suction,
- une ventouse dont les bords libres sont destinés à être en contact avec la surface externe de la portion de peau, servant à dilater les couches de ladite portion de peau,a suction cup, the free edges of which are intended to be in contact with the external surface of the skin portion, serving to dilate the layers of said skin portion,
- une canule servant à la liposuccion de la graisse sous ladite portion de peau, la canule et la ventouse étant reliées au même dit moyen d'aspiration, chacune par une conduite. Brève description des dessins- A cannula used for liposuction of the fat under said portion of skin, the cannula and the suction cup being connected to the same said suction means, each by a pipe. Brief description of the drawings
D'autres avantages et caractéristiques seront mieux compris à la lecture de la description qui va suivre d'exemples de réalisation, par référence aux dessins schématiques annexés, qui ne sont nullement limitatifs mais fournis à titre d'illustration. Dans les dessins annexés, la figure 1 représente une vue en perspective d'un dispositif de liposuccion des graisses associé à un traitement corporel par aspiration sous vide et ultrasons selon l'invention ; et la figure 2 représente une vue en perspective d'un autre dispositif selon l'invention.Other advantages and characteristics will be better understood on reading the following description of exemplary embodiments, with reference to the appended schematic drawings, which are in no way limiting but are provided by way of illustration. In the accompanying drawings, Figure 1 shows a perspective view of a fat liposuction device associated with a body treatment by vacuum suction and ultrasound according to the invention; and Figure 2 shows a perspective view of another device according to the invention.
Description détaillée de l'inventionDetailed description of the invention
Le dispositif de liposuccion et de traitement de la peau est moins encombrant et d'un maniement plus aisé que les dispositifs antérieurs de liposuccion, puisque le moyen d'aspiration est à usage multiple. Selon la présente invention, le dispositif de liposuccion comprend de façon avantageuse un moyen fournissant un champ d'ultrasons, servant à exposer à un champ d'ultrasons une zone de la portion de peau. Un traitement complémentaire de la peau aux ultrasons permet comme on l'a précédemment indiqué de limiter les inconvénients vis-à-vis de la peau du traitement par aspiration sous vide. De façon avantageuse, la conduite d'aspiration reliée à la ventouse comportera une valve de fermeture et d'ouverture de ladite conduite. La fermeture de cette valve offre la possibilité d'arrêter l'aspiration de l'air dans la ventouse en contact avec la peau quand le vide dans ladite ventouse est suffisamment poussé pour permettre le traitement thérapeutique efficace par dilatation des couches (épiderme, derme et, le cas échéant hypoderme) de la zone corporelle du patient alors que l'aspiration des graisses se poursuit sous la peau. La fermeture de la valve permet également de maintenir la dépression dans la ventouse alors que l'aspiration des graisses par la pompe aspirante a cessé, la dilatation des couches de la peau pouvant ainsi être poursuivie même après la phase de liposuccion.The liposuction and skin treatment device is less bulky and easier to handle than previous liposuction devices, since the suction means is for multiple use. According to the present invention, the liposuction device advantageously comprises means providing an ultrasound field, serving to expose an area of the skin portion to an ultrasound field. An additional treatment of the skin with ultrasound makes it possible, as previously indicated, to limit the drawbacks vis-à-vis the skin of the treatment by vacuum suction. Advantageously, the suction pipe connected to the suction cup will include a valve for closing and opening said pipe. Closing this valve offers the possibility of stopping the suction of air into the suction cup in contact with the skin when the vacuum in said suction cup is sufficiently high to allow effective therapeutic treatment by dilation of the layers (epidermis, dermis and , if necessary hypodermis) of the patient's body area while the suction of fat continues under the skin. The closing of the valve also makes it possible to maintain the depression in the suction cup while the aspiration of fat by the suction pump has ceased, the dilation of the layers of the skin can thus be continued even after the liposuction phase.
En pratique, il est important que la canule possède une certaine liberté de mouvement par rapport à la ventouse et la tête à ultrasons. Cette liberté de mouvement facilite le travail du praticien qui peut ainsi mouvoir avec aisance la canule sous la peau sans entraîner un déplacement de la ventouse et du moyen fournissant le champ d'ultrasons placés sur la peau sensiblement au niveau de la zone corporelle sujette à liposuccion.In practice, it is important that the cannula has some freedom of movement relative to the suction cup and the ultrasonic head. This freedom of movement facilitates the work of the practitioner who can thus move the cannula with ease under the skin without causing a displacement of the suction cup and of the means providing the field of ultrasound placed on the skin substantially at the level of the body area subject to liposuction. .
La conduite reliée à la canule sera avantageusement en matière flexible ou souple au moins sur une partie de sa longueur du côté de ladite canule, ladite partie et ladite canule constituant une branche du dispositif mobile par rapport au reste du dispositif. La conduite en matière flexible ou souple à laquelle est reliée la canule offre une grande liberté de mouvement de ladite canule en dessous et autour de la ventouse et du moyen fournissant le champ d'ultrasons en place sur la peau lors de la phase de liposuccion. Selon une autre caractéristique, le dispositif selon l'invention comprend un moyen de mise sous pression d'air de la ventouse par mise en communication temporaire du volume interne de ladite ventouse avec l'atmosphère. Ainsi, le praticien peut dépressuriser à volonté la ventouse ce qui lui permet de pratiquer au cours de la liposuccion diverses phases de dilatation des couches corporelles et de diminuer rapidement si nécessaire le niveau de dépression de la ventouse en place sur la peau.The pipe connected to the cannula will advantageously be made of flexible or flexible material at least over part of its length on the side of said cannula, said part and said cannula constituting a branch of the mobile device relative to the rest of the device. The flexible or flexible material pipe to which the cannula is connected offers great freedom of movement of said cannula below and around the suction cup and of the means providing the ultrasound field in place on the skin during the liposuction phase. According to another characteristic, the device according to the invention comprises a means for pressurizing the suction cup air by placing the internal volume of said suction cup in temporary communication with the atmosphere. Thus, the practitioner can depressurize at will the suction cup which allows him to practice during liposuction various phases of dilation of the body layers and to quickly decrease if necessary the level of depression of the suction cup in place on the skin.
Selon l'invention, la portion de peau est avantageusement soumise à un cycle comprenant, en même temps que l'aspiration de la graisse à l'aide de la canule, les phases suivantes : - ouverture de la valve de fermeture et d'ouverture pour mise sous vide de la ventouse au contact de ladite portion de peau,According to the invention, the portion of skin is advantageously subjected to a cycle comprising, at the same time as the suction of the fat using the cannula, the following phases: - opening of the closing and opening valve for evacuating the suction cup in contact with said skin portion,
- obturation de la valve de la conduite reliée à la ventouse,- obturation of the valve of the pipe connected to the suction cup,
- mise sous pression d'air de la ventouse par le moyen de mise sous pression d'air, au moins une phase d'exposition de la portion de peau concernée (P) au champ d'ultrasons étant réalisée pendant ce cycle.- Air pressure of the suction cup by the air pressure means, at least one phase of exposure of the skin portion concerned (P) to the ultrasonic field being carried out during this cycle.
Le cycle de variation de la pression au sein de la ventouse au contact de la peau améliore l'efficacité du traitement de dilatation des chairs, ledit traitement devenant dynamique. La phase de mise sous pression d'air de la ventouse peut également être mis à profit pour déplacer la ventouse sur une autre portion de peau à traiter.The pressure variation cycle within the suction cup in contact with the skin improves the efficiency of the flesh dilation treatment, said treatment becoming dynamic. The air pressurization phase of the suction cup can also be used to move the suction cup onto another portion of skin to be treated.
Selon un mode préféré de réalisation de l'invention, au cours de chaque cycle, la phase d'exposition au champ d'ultrasons débute avant ou en même temps que le début de la mise sous vide ou dépression de la ventouse disposée sur la peau (P) [i.e. la phase d'aspiration sous vide dans la ventouse]. Comme on l'a mentionné précédemment, il est en effet, plutôt préférable pour obtenir un effet protecteur des ultrasons par rapport aux effets indésirables sur la peau de la phase d'aspiration pour dilater les couches de la peau, que l'exposition aux ultrasons se déroule simultanément à ladite phase d'aspiration.According to a preferred embodiment of the invention, during each cycle, the phase of exposure to the ultrasonic field begins before or at the same time as the start of the vacuuming or depression of the suction cup disposed on the skin (P) [ie the vacuum suction phase in the suction cup]. As previously mentioned, it is indeed rather preferable to obtain a protective effect of ultrasound compared to the undesirable effects on the skin of the suction phase to dilate the layers of the skin, than exposure to ultrasound. takes place simultaneously with said aspiration phase.
De façon encore plus avantageuse, au cours de chaque cycle, la durée de la phase d'exposition sous vide sera inférieure à celle de la phase d'exposition au champ d'ultrasons. Ainsi, les ultrasons peuvent préparer la peau à la phase d'aspiration pour dilater les couches de ladite peau et/ ou prolonger leurs effets après que ladite phase d'aspiration a cessé.Even more advantageously, during each cycle, the duration of the vacuum exposure phase will be less than that of the exposure phase to the ultrasound field. Thus, ultrasound can prepare the skin for the suction phase to dilate the layers of said skin and / or prolong their effects after said suction phase has ceased.
Le dispositif 1 de l'invention selon la figure 1 comporte une canule 2 introduite à travers la portion P de peau pour atteindre une zone A située sous ladite portion P où se trouve la graisse à aspirer. Le dispositif 1 comporte également :The device 1 of the invention according to FIG. 1 comprises a cannula 2 introduced through the portion P of skin to reach an area A situated under said portion P where the fat to be aspirated is located. The device 1 also includes:
- un moyen d'aspiration constitué par une pompe à aspiration (non représentée),- a suction means constituted by a suction pump (not shown),
- une ventouse 5 dont les bords libres sont en contact avec la surface externe de la portion P de peau, - une conduite 15 reliant la ventouse 5 à ladite pompe à aspiration, comprenant une valve 16 d'ouverture et de fermeture de ladite conduite 15, eta suction cup 5 whose free edges are in contact with the external surface of the skin portion P, a pipe 15 connecting the suction cup 5 to said suction pump, comprising a valve 16 for opening and closing said pipe 15, and
- une conduite 20 reliant la canule 2 à la même dite pompe à aspiration. Un gel conducteur des ultrasons peut également être appliqué préalablement sur la surface externe de la portion P de peau, ledit gel étant destiné à servir d'interface entre la tête à ultrasons 10 et la surface externe de la portion P de peau pour une meilleure transmission des ultrasons.- A line 20 connecting the cannula 2 to the same so-called suction pump. An ultrasonic conductive gel can also be applied beforehand to the external surface of the skin portion P, said gel being intended to serve as an interface between the ultrasonic head 10 and the external surface of the skin portion P for better transmission. ultrasound.
La ventouse 5 comporte un moyen de mise sous pression d'air, tel une valve 30, dont l'ouverture temporaire permet la mise en communication du volume interne de la ventouse avec l'atmosphère.The suction cup 5 comprises a means for pressurizing air, such as a valve 30, the temporary opening of which allows the internal volume of the suction cup to be placed in communication with the atmosphere.
De préférence, le dispositif de liposuccion 1 comprend également un moyen fournissant un champ d'ultrasons constitué par une tête à ultrasons 10 en liaison ultrasonique avec la portion P de peau, cette liaison ultrasonique étant réalisée par simple contact, au moyen d'un gel conducteur des ultrasons, entre la tête à ultrasons 10 et la surface externe de la portion P de peau.Preferably, the liposuction device 1 also comprises means providing an ultrasonic field constituted by an ultrasonic head 10 in ultrasonic connection with the portion P of skin, this ultrasonic connection being produced by simple contact, by means of a gel. ultrasonic conductor, between the ultrasonic head 10 and the external surface of the skin portion P.
Un manche 25 lié à la ventouse 5 et à la tête à ultrasons 10 permet de positionner correctement ces derniers éléments et éventuellement de les maintenir en place.A handle 25 linked to the suction cup 5 and to the ultrasonic head 10 makes it possible to correctly position these latter elements and possibly to keep them in place.
Un générateur d'ultrasons alimenté en courant électrique par un fil conducteur 12, en liaison avec la tête à ultrasons 10, est par exemple placé dans le manche 25.An ultrasonic generator supplied with electric current by a conducting wire 12, in connection with the ultrasonic head 10, is for example placed in the handle 25.
De préférence, la base de la ventouse 5, qui est destinée à être en contact sur la portion P de la peau, comporte un élément souple 6 sous forme par exemple de soufflets circulaires destiné à s'adapter convenablement aux reliefs de la peau tout en offrant la possibilité de donner une certaine orientation au manche 25 par rapport à la direction normale à la peau lorsque la ventouse est en place sur la portion P de la peau. La possibilité d'orienter le manche 25 est en effet intéressante pour l'éloigner légèrement du patient dans le cas où ce dernier serait gêné par la proximité dudit manche 25.Preferably, the base of the suction cup 5, which is intended to be in contact on the portion P of the skin, comprises a flexible element 6 in the form, for example, of circular bellows intended to adapt properly to the reliefs of the skin while offering the possibility of giving a certain orientation to the handle 25 relative to the direction normal to the skin when the suction cup is in place on the portion P of the skin. The possibility of orienting the handle 25 is in fact advantageous for moving it slightly away from the patient in the event that the latter is hampered by the proximity of said handle 25.
Ainsi, dès que la pompe à aspiration est mise en fonctionnement et que la valve 16 est ouverte laissant une libre circulation de l'air dans la conduite 15, celle-ci crée une dépression au sein de la ventouse 5 durant l'aspiration de la graisse de la zone A par la conduite 20, ce qui permet de dilater les couches de la portion P de peau. La graisse aspirée est recueillie dans un récipient non représenté sur les figures. Pendant cette phase d'aspiration, la tête à ultrasons 10 est susceptible de fournir ou fournit à la portion P de peau, un champ d'ultrasons.Thus, as soon as the suction pump is put into operation and the valve 16 is open leaving a free circulation of air in the pipe 15, the latter creates a depression within the suction cup 5 during suction of the fat from zone A via line 20, which makes it possible to dilate the layers of the portion P of skin. The sucked fat is collected in a container not shown in the figures. During this suction phase, the ultrasonic head 10 is capable of supplying or providing the skin portion P with an ultrasound field.
La conduite 20 est réalisée de préférence dans un matériau flexible sur une partie libre de sa longueur proche de la canule 2. La canule 2 et ladite partie flexible constitue ainsi une sorte de branche souple ce qui permet d'orienter et de déplacer la canule 2 par rapport au reste du dispositif qui peut rester fixe sur la portion P de la peau. Pour faciliter la manipulation de la canule 2, un manche 3 rigide peut être prévu.The pipe 20 is preferably made of a flexible material over a free part of its length close to the cannula 2. The cannula 2 and said flexible part thus constitutes a sort of flexible branch which makes it possible to orient and move the cannula 2 compared to the rest of the device which can remain fixed on the portion P of the skin. To facilitate handling of the cannula 2, a rigid handle 3 can be provided.
On préconise le cycle suivant lors du fonctionnement de la pompe à aspiration et de la liposuccion de la graisse au sein de la zone A :The following cycle is recommended during operation of the suction pump and liposuction of the fat within zone A:
- ouverture de la valve 16 de la conduite 15 pour mise sous vide de la ventouse 5 au contact de la portion P de peau par aspiration d'air grâce à la pompe à aspiration,opening of the valve 16 of the pipe 15 for placing the suction cup 5 under vacuum in contact with the portion P of the skin by suction of air using the suction pump,
- obturation de la valve 16 de la conduite 15 reliée à la ventouse 5,closing the valve 16 of the pipe 15 connected to the suction cup 5,
- mise sous pression d'air de la ventouse 5 par le moyen de mise sous pression d'air en ouvrant temporairement la valve 30 mettant le volume interne de la ventouse 5 en communication avec l'atmosphère pendant un temps prédéfini, au moins une phase d'exposition de la portion P de peau au champ d'ultrasons par l'intermédiaire de la tête à ultrasons 10 étant réalisée pendant ce cycle. De préférence durant ce cycle, l'ouverture et la fermeture successives des valves 16 et 30 seront pilotées par un dispositif automatique de commande dont les ordres d'ouverture et de fermeture à intervalles réguliers peuvent être programmés.- air pressure of the suction cup 5 by the air pressure means by temporarily opening the valve 30 putting the internal volume of the suction cup 5 in communication with the atmosphere for a predefined time, at least one phase of exposure of the portion P of skin to the ultrasound field via the ultrasound head 10 being carried out during this cycle. Preferably during this cycle, the successive opening and closing of the valves 16 and 30 will be controlled by an automatic control device whose opening and closing orders at regular intervals can be programmed.
Au cours de chaque cycle, la phase d'exposition au champ d'ultrasons est réalisée pendant la phase d'aspiration sous vide, la durée de ladite phase d'exposition sous vide pouvant être inférieure à celle de ladite phase d'exposition au champ d'ultrasons.During each cycle, the ultrasonic field exposure phase is carried out during the vacuum suction phase, the duration of said vacuum exposure phase being able to be less than that of said field exposure phase. ultrasound.
La description ci-dessus pour illustrer l'invention ne saurait en limiter la portée. Ainsi, comme représenté sur la figure 2, la tête à ultrasons 10 peut se confondre avec la ventouse 5 ou une partie de la ventouse 5 en liaison avec le générateur s'étendant entre les bords libres de ladite ventouse 5 et le générateur à ultrasons, ladite ventouse 5 ou ladite partie étant nécessairement réalisée dans un matériau conduisant les ultrasons tel un plastique rigide, un verre ou un métal. Dans ce cas, le dispositif générateur d'ultrasons est au contact de la ventouse 5 ou de ladite partie pour lui transmettre les ultrasons qui seront ensuite acheminés jusqu'à la portion P de la peau.The above description to illustrate the invention should not limit its scope. Thus, as shown in FIG. 2, the ultrasonic head 10 can merge with the suction cup 5 or a part of the suction cup 5 in connection with the generator extending between the free edges of said suction cup 5 and the ultrasonic generator, said suction cup 5 or said part necessarily being made of a material conducting ultrasound such as a rigid plastic, a glass or a metal. In this case, the ultrasound generating device is in contact with the suction cup 5 or said part to transmit the ultrasound to it which will then be conveyed to the portion P of the skin.
La ventouse 5 peut également être prévue orientable par rapport au manche 25 pour faciliter sa pose sur la surface externe de la portion P de peau à traiter.The suction cup 5 can also be provided orientable relative to the handle 25 to facilitate its installation on the external surface of the portion P of skin to be treated.
D'autre part, la conduite 20 peut être rigide au lieu d'être souple. Une liaison 50 non rigide du type liaison rotule avec le manche 25 assure alors la mobilité de la canule 2 par rapport à la ventouse 5 et la tête à ultrasons 10. Dans ce dernier cas, il peut être prévu également de pouvoir démonter le manche 25 et les organes y étant rattachés comme la tête à ultrasons 10 et la ventouse 5 par extraction de la rotule, rattachée soit au manche 25 soit à la conduite 20, de son logement placé sur l'autre élément manche 25 ou conduite 20.On the other hand, the pipe 20 can be rigid instead of being flexible. A non-rigid connection 50 of the ball joint connection type with the handle 25 then ensures the mobility of the cannula 2 relative to the suction cup 5 and the ultrasonic head 10. In the latter case, provision may also be made to be able to dismantle the handle 25 and the organs attached thereto such as the ultrasonic head 10 and the suction cup 5 by extraction of the ball joint, attached either to the handle 25 or to the pipe 20, from its housing placed on the other handle 25 or pipe 20 element.
Il est envisageable aussi de déplacer la ventouse 2 soumise au cycle de dépression et de mise sous pression précité et la tête à ultrasons 10 afin d'obtenir un effet de massage de la peau. It is also possible to move the suction cup 2 subjected to the aforementioned vacuum and pressurization cycle and the ultrasonic head 10 in order to obtain a massage effect on the skin.
