Abstract
Description
CONFORMATEUR POUR VOIES LACRYMALES
La présente invention a pour objet un conformateur permettant la formation d'une dérivation lacrymale.CONFORMER FOR LACRYMAL TRACKS
The subject of the present invention is a conformator allowing the formation of a lacrimal diversion.
On sait que le liquide lacrymal généré s'écoule normalement pour sa plus grande partie dans le sac lacrymal puis dans la fosse nasale. A la suite de certaines maladies, il arrive que les voies lacrymales s'obstruent et qu'il ne soit pas possible de rétablir leur fonctionnement normal.We know that the generated tear fluid normally flows for the most part in the lacrimal sac and then in the nasal cavity. Following certain diseases, it happens that the lacrimal passages become obstructed and that it is not possible to restore their normal functioning.
Pour pallier cet inconvénient, il est connu, depuis très longtemps, de procéder à une opération appelée
DACRYOCYSTORHINOSTOMIE ou DCR qui consiste à créer un canal d'écoulement direct des larmes dans la fosse nasale, sans passer par le canal lacrymal obstrué.To overcome this drawback, it has been known for a very long time to carry out an operation called
DACRYOCYSTORHINOSTOMY or DCR which consists in creating a channel for the direct flow of tears in the nasal cavity, without passing through the obstructed lacrimal channel.
A cet effet, après ouverture de la peau, on crée dans l'os du nez une ouverture reliant le sac lacrymal et la fosse nasale correspondante. La muqueuse de la paroi nasale est suturée avec la muqueuse du sac lacrymal à l'intérieur de l'ouverture créée de sorte que les larmes s'écoulent directement dans la fosse nasale.For this purpose, after opening the skin, an opening is created in the nose bone connecting the lacrimal sac and the corresponding nasal cavity. The lining of the nasal wall is sutured with the lining of the lacrimal sac inside the opening created so that the tears flow directly into the nasal cavity.
Malheureusement, les parois de l'ouverture ont parfois tendance par prolifération à obstruer l'anastomose réalisée en regard du canal d'union ce qui empêche l'écoulement des larmes et ramène à la situation antérieure.Unfortunately, the walls of the opening sometimes tend by proliferation to obstruct the anastomosis performed opposite the union channel which prevents the flow of tears and brings back to the previous situation.
La présente invention a pour objet de pallier cet inconvénient et de permettre le maintien de l'ouverture pendant le temps nécessaire à la cicatrisation des muqueuses autour de l'ouverture osseuse qui est de l'ordre de deux à trois mois.The object of the present invention is to overcome this drawback and to allow the opening to be maintained for the time necessary for the healing of the mucous membranes around the bone opening which is of the order of two to three months.
Selon l'invention, le conformateur pour DCR est caractérisé en ce qu'il comprend un corps oblong percé de deux canaux de passage pour une sonde bicanaliculaire.According to the invention, the DCR shaper is characterized in that it comprises an oblong body pierced with two passage channels for a two-channel probe.
Ainsi, le conformateur peut être ajusté en position en glissant sur la sonde et rester maintenu dans la position correcte. Or ce problème du maintien du conformateur en position est essentiel et n'a été jusqu'à ce jour que mal résolu. Par ailleurs, le mode de suspension du conformateur sur la sonde permet à ce dernier de légers déplacements lorsque les paupières se ferment permettant d'éviter des sténoses.Thus, the conformator can be adjusted in position by sliding on the probe and remain held in the correct position. However, this problem of maintaining the conformator in position is essential and has so far been poorly resolved. Furthermore, the mode of suspension of the conformator on the probe allows the latter to move slightly when the eyelids close, thereby avoiding strictures.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre de modes particuliers de réalisation, donnés uniquement à titre d'exemples non limitatifs, en regard des dessins qui représentent
- La Figure 1, une vue schematique d'une DCR;
- La Figure 2, une vue d'un conformateur selon l'invention.Other characteristics and advantages of the invention will appear during the following description of particular embodiments, given only by way of nonlimiting examples, with reference to the drawings which represent
- Figure 1, a schematic view of a DCR;
- Figure 2, a view of a shaper according to the invention.
Sur la figure 1, on distingue très schématiquement un orbite oculaire avec l'oeil correspondant et une fosse nasale F,N,.In Figure 1, there is very schematically an eye socket with the corresponding eye and a nasal fossa F, N ,.
Le sac lacrymal S.L. est maintenu dans la gouttière lacrymale et correspond avec la fosse nasale F,N, par l'intermédiaire d'un canal lacrymo-nasal contenu dans une gouttière osseuse.The lacrimal sac S.L. is held in the lacrimal groove and corresponds with the nasal fossa F, N, via a lacrmo-nasal canal contained in a bony groove.
Lorsque le canal lacrymo-nasal est obturé, sans pouvoir être débouché, une ouverture O est percée , après une ouverture de la peau, dans l'os de la fosse nasale F,N, pour constituer une anastomose entre les muqueuses du nez et du sac lacrymal suturées ensemble. Il est souvent nécessaire, afin de bien dégager un passage d'introduire par les méats canaliculaires une sonde bicanaliculaire 1.When the lacrmo-nasal canal is closed, without being able to be unclogged, an opening O is pierced, after an opening of the skin, in the bone of the nasal fossa F, N, to constitute an anastomosis between the mucous membranes of the nose and the lacrimal sac sutured together. In order to clear a passage, it is often necessary to introduce a two-channel probe 1 through the canalicular channels.
Conformément à l'invention, la sonde 1 passe à travers un conformateur 2. De préférence, le conformateur 2 a une forme ovoïde ce qui permet d'éviter toute aspérité ou angle aigu susceptible de blesser les muqueuses en formation et de produire des déchirements. Le conformateur est de préférence réalisé en silicone comme les brins du tube qui se terminent à leurs extrémités par des mandrins métalliques, ceux-ci n'étant nécessaires que pour le temps opératoire.According to the invention, the probe 1 passes through a shaping device 2. Preferably, the shaping device 2 has an ovoid shape which makes it possible to avoid any asperity or acute angle liable to injure the mucous membranes in formation and to produce tears. The shaping device is preferably made of silicone like the strands of the tube which terminate at their ends by metal mandrels, these being necessary only for the operating time.
Comme cela est schématisé sur la figure 2, le liquide lacrymal s'écoule d'abord autour du tube de la sonde 1, puis autour du conformateur. Les brins 3 passent à travers deux orifices 4 de même diamètre que les brins de manière à produire un frottement doux permettant un léger débattement du conformateur 2 sur la sonde 1.As shown diagrammatically in FIG. 2, the lacrimal liquid first flows around the tube of the probe 1, then around the conformator. The strands 3 pass through two orifices 4 of the same diameter as the strands so as to produce a gentle friction allowing a slight movement of the shaper 2 on the probe 1.
Dans l'exemple représenté le conformateur 2 présente sensiblement la forme dune olive. Cette forme n'est pas nécessaire et peut être modifiée, la présente invention concernant le montage autostable du conformateur sur la sonde. Dans le même ordre d idées, il n'est pas nécessaire que le conformateur soit en silicone pur et tout autre matériau biocompatible peut convenir.In the example shown the shaper 2 has substantially the shape of an olive. This shape is not necessary and can be modified, the present invention relating to the freestanding mounting of the shaper on the probe. In the same vein, the shaper need not be made of pure silicone and any other biocompatible material may be suitable.
Il va de soi que de nombreuses variantes peuvent être apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de l'invention. It goes without saying that many variants can be made, in particular by substitution of equivalent technical means, without departing from the scope of the invention.
