Description

La présente invention a pour objet un dispositif de drain lacrymal maintenu en place grâce à un filetage externe. <Desc / Clms Page number 1>
The present invention relates to a tear drain device held in place by means of an external thread.
Elle se rapporte d'une manière générale aux techniques destinées à assurer ou à rétablir la perméabilité des voies lacrymales. It relates generally to techniques intended to ensure or restore the permeability of the lacrimal passages.
Le fonctionnement normal d'un oeil humain nécessite que sa surface externe soit recouverte en permanence d'un film lubrifiant constitué par les larmes qui assurent à la fois un rinçage et une protection grâce aux antibiotiques naturels anti-infectieux qu'elles contiennent. Elles sont produites par une série de glandes se trouvant dans les paupières et dans le pourtour de l'oeil. The normal functioning of a human eye requires that its external surface be permanently covered with a lubricating film constituted by tears which ensure both rinsing and protection thanks to the natural anti-infectious antibiotics which they contain. They are produced by a series of glands found in the eyelids and around the eye.
La déficience du maintien de la stabilité de ce film sur le globe oculaire peut entraîner divers désagréments tels que picotements, irritations, sensations de brûlure et dégradation de la vision en cas de manque d'humidité de la surface de l'oeil, ou un excès de lames provoquant des yeux rouges et obligeant le patient à s'essuyer fréquemment le visage. Failure to maintain the stability of this film on the eyeball can lead to various discomforts such as tingling, irritation, burning sensations and deterioration of vision in the event of lack of moisture in the surface of the eye, or excess blades causing red eyes and forcing the patient to frequently wipe his face.
Les larmes sont produites continuellement, l'excès de fluide étant drainé de la surface du globe oculaire 1 à travers deux ouvertures ponctuelles constituant les points lacrymaux supérieur 2 et inférieur 3 situés près du coin interne de l'oeil et communiquant avec des conduits connus sous le nom de canalicules 4, 5 aboutissant à un sac lacrymal 6 qui se déverse dans la fosse nasale 7 (figure 1). Tears are produced continuously, the excess fluid being drained from the surface of the eyeball 1 through two punctual openings constituting the upper 2 and lower 3 tear points located near the inner corner of the eye and communicating with conduits known as the name of canaliculi 4, 5 leading to a lacrimal sac 6 which pours into the nasal cavity 7 (Figure 1).
Le manque de fluide lacrymal sur le globe oculaire est dû en général à une insuffisance des glandes productrices pouvant être provoqué par l'âge ou par d'autres causes. La trop grande quantité de larmes peut en particulier être causée par une obstruction des canaux lacrymaux. Dans les deux cas, on peut améliorer la situation en agissant sur ces canaux, soit en les bouchant, totalement ou partiellement, soit au contraire en les maintenant ouverts. The lack of lacrimal fluid on the eyeball is generally due to an insufficiency of the producing glands which can be caused by age or by other causes. Too much tears can be caused in particular by an obstruction in the tear ducts. In both cases, the situation can be improved by acting on these channels, either by blocking them, totally or partially, or on the contrary by keeping them open.
En particulier, l'occlusion permanente, éventuellement par voie chirurgicale (cautérisation, laser), des conduits lacrymaux peut être une méthode de In particular, permanent occlusion, possibly by the surgical route (cauterization, laser), of the lacrimal ducts can be a method of

traitement des déficiences relatives aux larmes. Lorsque l'écoulement des larmes dans les voies lacrymales est ainsi empêché, le volume des larmes restantes procure une plus forte humidité. Cette méthode présente l'inconvénient d'être irréversible, à moins d'une nouvelle intervention chirurgicale. treatment of tear deficiencies. When the flow of tears in the lacrimal passages is thus prevented, the volume of the remaining tears provides higher humidity. This method has the disadvantage of being irreversible, unless a new surgical intervention.
Les dispositifs connus, implantés dans les voies lacrymales et destinés à empêcher ou à faciliter l'écoulement de larmes, présentent des risques de migration ou d'expulsion accidentelles. Ils nécessitent en outre une instrumentation particulière pour la mise en place et l'extraction. Known devices, implanted in the lacrimal passages and intended to prevent or facilitate the flow of tears, present risks of accidental migration or expulsion. They also require special instrumentation for placement and extraction.
Le brevet N WO 98I33 461 déposé par M. Alain FOUERÉ, co-déposant de la présente demande, décrit un tampon méatique vissable destiné à être implanté dans les points lacrymaux et constitué d'un corps sensiblement cylindrique dont la surface latérale comporte un filet hélicoïdal semblable à celui d'une vis permettant de le mettre en place ou de le retirer par vissage ou dévissage. Patent N WO 98I33 461 filed by Mr. Alain FOUERÉ, co-applicant of the present application, describes a screwable meatic pad intended to be implanted in the lacrimal points and consisting of a substantially cylindrical body whose lateral surface comprises a helical thread similar to that of a screw allowing it to be put in place or removed by screwing or unscrewing.
Cet implant ne permet cependant d'intervenir que sur les points lacrymaux 2, 3 et non sur les autres parties du système d'écoulement des larmes telles que les canalicules 4, 5 (cf figure 1). However, this implant only makes it possible to intervene on the lacrimal points 2, 3 and not on the other parts of the tear flow system such as the canaliculi 4, 5 (cf. FIG. 1).
Le dispositif selon la présente invention a pour objectif de permettre le rétablissement d'un écoulement normal du liquide lacrymal quelles que soient les causes ayant provoqué sa perturbation, tout en améliorant la fixation de l'implant et en facilitant sa mise en place. The device according to the present invention aims to allow the restoration of a normal flow of tear fluid whatever the causes having caused its disturbance, while improving the fixation of the implant and facilitating its implementation.
II est constitué d'un élément tubulaire de section quelconque comportant un ou plusieurs filetages externes permettant sa mise en place et son maintien par vissage, ou son extraction par dévissage, et déterminé pour faire communiquer la surface de l'oeil avec le sac lacrymal ou la fosse nasale pour assurer un écoulement normal des larmes dans cette dernière. It consists of a tubular element of any cross section comprising one or more external threads enabling it to be inserted and maintained by screwing, or its extraction by unscrewing, and determined to make the surface of the eye communicate with the lacrimal sac or the nasal cavity to ensure a normal flow of tears in the latter.
Sur les dessins annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention: la figure 1, déjà citée, représente schématiquement un oeil avec les canaux lacrymaux et le sac lacrymal, In the appended drawings, given by way of nonlimiting examples of embodiments of the subject of the invention: FIG. 1, already cited, schematically represents an eye with the lacrimal canals and the lacrimal sac,
<Desc/Clms Page number 3><Desc / Clms Page number 3>
la figure 2 montre un drain à tête filetée implanté dans les conduits lacrymaux, la figure 3 est une vue partielle agrandie du drain de la figure 2 et les figures 4 et 5 montrent respectivement vu de côté et en coupe axiale un drain implanté dans un conduit réalisé par voie chirurgicale. Figure 2 shows a threaded head drain implanted in the tear ducts, Figure 3 is a partial enlarged view of the drain of Figure 2 and Figures 4 and 5 show respectively seen from the side and in axial section a drain implanted in a duct performed surgically.
Le dispositif, figures 2 à 5, est constitué d'un drain tubulaire 8, 9 comportant une ou plusieurs parties filetées permettant de l'insérer ou de le retirer par vissage ou dévissage. The device, FIGS. 2 to 5, consists of a tubular drain 8, 9 comprising one or more threaded parts allowing it to be inserted or removed by screwing or unscrewing.
Sur les figures 2 et 3, on peut voir un drain 8 implanté dans le canalicule inférieur 5 et dans le sac lacrymal 6. Ce drain est constitué d'une partie tubulaire flexible 11 et d'une tête filetée 12 destinée à être vissée dans l'un des points lacrymaux 2, 3 ou à un autre emplacement de la surface de l'oeil. Cette tête peut être cylindrique, tronconique ou encore présenter la forme d'un double tronc de cône, le diamètre de la partie filetée étant successivement croissant puis décroissant. In FIGS. 2 and 3, we can see a drain 8 implanted in the lower canaliculus 5 and in the lacrimal sac 6. This drain consists of a flexible tubular part 11 and a threaded head 12 intended to be screwed into the '' one of the lacrimal points 2, 3 or at another location on the surface of the eye. This head can be cylindrical, frustoconical or even have the shape of a double truncated cone, the diameter of the threaded part being successively increasing then decreasing.
La jonction de la tête 12 avec la partie tubulaire 11 peut former un joint tournant permettant une rotation indépendante de ces deux constituants. The junction of the head 12 with the tubular part 11 can form a rotary joint allowing independent rotation of these two constituents.
Les figures 4 et 5 montrent des drains 9 à double filetage destinés à être introduits dans un conduit réalisé par voie chirurgicale et reliant la surface du globe oculaire (ici l'angle interne 14 de l'oeil) au sac lacrymal 6 ou à la fosse nasale 7. FIGS. 4 and 5 show drains 9 with double threads intended to be introduced into a conduit produced surgically and connecting the surface of the eyeball (here the internal angle 14 of the eye) to the lacrimal sac 6 or to the fossa nasal 7.
L'extrémité externe, côté oeil, du drain peut avantageusement être pourvue d'une collerette 13 destinée à empêcher l'implant de pénétrer trop profondément à l'intérieur du conduit lacrymal ou chirurgical. The external end, eye side, of the drain can advantageously be provided with a collar 13 intended to prevent the implant from penetrating too deeply inside the lacrimal or surgical duct.
Dans certains cas, et en particulier lors d'une dacryocystorhinos- tomie, on pourra implanter à partir des fosses nasales 7 un drain 9 faisant communiquer lesdites fosses nasales avec le sac lacrymal 6, dans l'ostéotomie réalisée chirurgicalement. In certain cases, and in particular during a dacryocystorhinostomy, it will be possible to implant, from the nasal fossa 7, a drain 9 making said nasal fossa communicate with the lacrimal sac 6, in the osteotomy performed surgically.
<Desc/Clms Page number 4><Desc / Clms Page number 4>
La section du filetage pourra revêtir des formes diverses. Elle pourra en particulier être de type semi-circulaire, triangulaire ou trapézoïdal. The thread section may take various forms. It may in particular be of the semi-circular, triangular or trapezoidal type.
Dans le but de faciliter l'écoulement du liquide lacrymal, le corps tubulaire du drain 8, 9 pourra avantageusement comporter une ou plusieurs perforations dans sa périphérie, faisant communiquer le canal interne du drain avec sa paroi externe, ces perforations pouvant être réparties radialement et/ou axialement. In order to facilitate the flow of tear fluid, the tubular body of the drain 8, 9 may advantageously include one or more perforations in its periphery, making the internal channel of the drain communicate with its external wall, these perforations being able to be distributed radially and / or axially.
Le drain lacrymal 8, 9 sera de préférence fabriqué dans un matériau synthétique insoluble semi-rigide ou souple de qualité physiologique, tel que le silicone, le polyéthylène ou le téflon. Pour certaines applications, il pourra cependant être réalisé en métal, en verre "pyrex" ou dans un matériau résorbable, par exemple l'hydroxyapathite ou le corail taillé. The lacrimal drain 8, 9 will preferably be made from a semi-rigid or flexible insoluble synthetic material of physiological quality, such as silicone, polyethylene or teflon. For certain applications, it may however be made of metal, of "pyrex" glass or of an absorbable material, for example hydroxyapathite or cut coral.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
