Description
II
La présente invention concerne un dispositif utilisable notamment en chirurgie pour permettre l'écoulement d'un liquide jusqu'à un cône de réception par passage de ce liquide à travers un orifice réalisé dans la paroi d'un tube guide. The present invention relates to a device which can be used in particular in surgery to allow the flow of a liquid to a reception cone by passage of this liquid through an orifice produced in the wall of a guide tube.
L'écoulement de ce liquide est actuellement réalisé directement à partir d'une seringue connectée à une canule, cette dernière pouvant être indépendante ou solidarisée au cône de réception du liquide. Ces procédés d'écoulement "à ciel ouvert" n'évitent pas le risque d'éclaboussures du liquide hors du cône, sachant que ce liquide est alcoolisé et que le cône de réception repose sur une surface sensible (cornée d'un oeil) et limitée à un certain diamètre. The flow of this liquid is currently carried out directly from a syringe connected to a cannula, the latter being able to be independent or secured to the cone for receiving the liquid. These "open" flow methods do not avoid the risk of liquid splashing out of the cone, knowing that this liquid is alcoholic and that the receiving cone rests on a sensitive surface (cornea of one eye) and limited to a certain diameter.
Le dispositif selon l'invention permet de remédier à cet inconvénient en réalisant un système "fermé" de délivrance de ce liquide, le liquide alcoolisé ne devant être déposé que sur la surface du cône de réception et 15 surtout pas en dehors de celle-ci. Le dispositif selon l'invention comporte en effet selon une première caractéristique deux tubes introduits l'un dans l'autre. Le premier tube (A) a une situation interne par rapport au second tube (B). Il comporte à son 1/3 moyen une surface perforée d'un orifice. Le deuxième tube ( B), évasé en réservoir à une de ses extrémités 20 (supérieure) , joue le rôle de contenant par rapport au premier tube. Cette partie évasée du tube ( B) est remplie de liquide. Les faces externe du tube A et interne du tube B sont en contact étroit entre elles. Le déplacement d'un tube par rapport à l'autre permet la mise en contact direct de l'orifice du tube A avec la partie évasée du tube B qui contient le 25 liquide. Cette mise en contact entraine le passage du liquide contenu dans la partie évasée du tube B directement dans le tube A. Le liquide s'écoulera alors le long de la face interne du tube A jusqu'au cône de réception par passage du liquide à travers l'orifice du tube A, cet écoulement pouvant être interrompu à tout moment en faisant la manoeuvre inverse de déplacement du tube (A) , la face interne du tube (B) obstruant alors l'orifice situé sur le tube (A) Selon des modes particuliers de réalisation: - l'extrémité inférieure du tube B peut être le cône de réception. The device according to the invention overcomes this drawback by providing a "closed" system for delivering this liquid, the alcoholic liquid having to be deposited only on the surface of the reception cone and above all not outside of it. . The device according to the invention in fact comprises, according to a first characteristic, two tubes inserted one into the other. The first tube (A) has an internal position with respect to the second tube (B). It has at its 1/3 average a perforated surface with an orifice. The second tube (B), flared in a tank at one of its ends 20 (upper), acts as a container with respect to the first tube. This flared part of the tube (B) is filled with liquid. The external faces of tube A and internal of tube B are in close contact with each other. The displacement of one tube relative to the other allows the orifice of tube A to be brought into direct contact with the flared part of tube B which contains the liquid. This bringing into contact causes the liquid contained in the flared part of the tube B to pass directly into the tube A. The liquid will then flow along the internal face of the tube A to the receiving cone by passage of the liquid through the orifice of the tube A, this flow being able to be interrupted at any time by doing the reverse movement movement of the tube (A), the internal face of the tube (B) then obstructing the orifice located on the tube (A) According to particular embodiments: - the lower end of the tube B can be the reception cone.
- l'extrémité supérieure du tube A peut être ouverte, ou fermée en permanence ou en alternance, évasée ( occluant l'extrémité du tube B) ou non. - l'extrémité inférieure du tube A peut être une lame circulaire (trépan) - l'orifice latéral du tube A peut avoir une forme variable (par exemple circulaire, ovalaire, triangulaire, rectangulaire, ... ). - The upper end of tube A can be open, or closed permanently or alternately, flared (occluding the end of tube B) or not. - the lower end of tube A can be a circular blade (drill bit) - the lateral orifice of tube A can have a variable shape (for example circular, oval, triangular, rectangular, ...).
- le dessin de l'orifice latéral du tube A peut permettre un débit d'écoulement variable du liquide (par exemple triangulaire à base inférieure, losangique...) . - la taille de l'orifice latéral du tube A peut être variable micrométrique, millimétrique, ... ). - the design of the lateral opening of the tube A can allow a variable flow rate of the liquid (for example triangular with lower base, lozenge ...). - the size of the lateral orifice of the tube A can be variable micrometric, millimeter, ...).
- le nombre d'orifices réalisés sur la face latérale du tube A peut être variable, unique ou multiple. - The number of orifices made on the lateral face of the tube A can be variable, single or multiple.
- la face externe de l'orifice latéral du tube A peut être biseautée pour faciliter le passage du liquide à travers lui. - The external face of the lateral orifice of the tube A can be bevelled to facilitate the passage of the liquid through it.
- la localisation de l'orifice latéral du tube A peut être située sur une 20 hauteur variable du tube A ( sur un même étage circonférentiel ou en spirale) , et peut se situer à n'importe quelle hauteur du tube A. - le déplacement des deux tubes A et B entre eux peut se faire par exemple par coulissage simple, ou par tout procédé de vissage, ou par tout autre moyen. - the location of the lateral orifice of tube A can be located on a variable height of tube A (on the same circumferential or spiral stage), and can be located at any height of tube A. - displacement of the two tubes A and B between them can be done for example by simple sliding, or by any screwing process, or by any other means.
- la hauteur de l'ensemble du dispositif peut être variable. - the height of the entire device can be variable.
- le diamètre de chacun des tubes peut être variable. - the diameter of each of the tubes can be variable.
- la partie évasée du tube B peut être située entre les deux extrémités du tube B et prendre une forme arrondie ou ovalaire. - the flared part of tube B can be located between the two ends of tube B and take a rounded or oval shape.
- un manche peut être connecté au tube B. Les dessins annexés illustrent l'invention: La figure 1 représente le dispositif de l'invention incluant la Fig. la représentant le tube (A) et la Fig. lb représentant le tube ( B) . La figure 2 représente une variante du dispositif de l'invention. - a handle can be connected to tube B. The attached drawings illustrate the invention: FIG. 1 represents the device of the invention including FIG. representing it the tube (A) and FIG. lb representing the tube (B). FIG. 2 represents a variant of the device of the invention.
La figure 3 représente en coupe le dispositif de l'invention selon un procédé de vissage entre les tubes A et B, incluant la Fig. 3a représentant une coupe de l'ensemble du dispositif et la Fig.3b représentant une coupe horizontale passant par la bague de vissage ( 7). FIG. 3 represents in section the device of the invention according to a method of screwing between the tubes A and B, including FIG. 3a showing a section through the entire device and Fig.3b showing a horizontal section passing through the screw ring (7).
En référence à ces dessins, le dispositif comporte deux tubes coulissant 10 l'un dans l'autre: un tube interne (A) situé dans un tube externe ( B). Le tube A présente à son tiers moyen ( 1) une surface percée d'un orifice ( 2) . La face externe ( 3) du tube A est étroitement appliquée sur la face interne ( 4) du tube B. Le tube B est évasé à sa partie supérieure tel un réservoir ( 5) qui sera 15 rempli de liquide. Le tube A peut lui aussi être évasé a sa partie supérieure (13) occluant l'extrémité supérieure évasée (5) du tube B. Le réservoir ( 5) peut comporter à son bord supérieur un petit rebord ( 9) incliné vers l'intérieur du tube ( B) afin d'éviter tout débordement de liquide. Un manche ( 12) peut être connecté au tube ( B) . La situation de l'orifice ( 2) dans le tube A est telle que lorsque l'utilisateur fait coulisser vers le haut le tube A dans le tube B, il met en contact direct cet orifice ( 2) avec la partie évasée ( 5) du tube B, provoquant l'écoulement de liquide de la partie évasée ( 5) du tube B vers la face interne ( 6) du tube A, jusqu'à l'extrémité inférieure du tube B (11). 25 Inversement, l'écoulement de liquide dans le tube A peut être interrompu à volonté simplement en faisant coulisser vers le bas le tube A dans le tube B, la face interne ( 4) du tube B obstruant alors l'orifice ( 2) du tube A. A titre d'exemple non limitatif, le diamètre du tube interne A sera de 8 mm et sa hauteur de 2 cm. With reference to these drawings, the device comprises two sliding tubes 10 one inside the other: an internal tube (A) situated in an external tube (B). The tube A has at its middle third (1) a surface pierced with an orifice (2). The external face (3) of the tube A is tightly applied to the internal face (4) of the tube B. The tube B is flared at its upper part like a reservoir (5) which will be filled with liquid. The tube A can also be flared at its upper part (13) occluding the flared upper end (5) of the tube B. The reservoir (5) may have at its upper edge a small rim (9) inclined inwards of the tube (B) to avoid any overflow of liquid. A handle (12) can be connected to the tube (B). The position of the orifice (2) in the tube A is such that when the user slides up the tube A in the tube B, he puts this orifice (2) in direct contact with the flared part (5) from tube B, causing the liquid to flow from the flared part (5) of tube B towards the internal face (6) of tube A, up to the lower end of tube B (11). Conversely, the flow of liquid in the tube A can be stopped at will simply by sliding the tube A downwards in the tube B, the internal face (4) of the tube B then obstructing the orifice (2) of the tube A. By way of nonlimiting example, the diameter of the internal tube A will be 8 mm and its height 2 cm.
Le dispositif selon l'invention est particulièrement destiné à permettre l'écoulement protégé dans un système fermé , de liquide alcoolisé d'un 5 réservoir vers l'intérieur d'un tube, pour être déposé dans un cône de réception reposant sur une surface oculaire ( cornée) , surface strictement limitée à celle du cône de réception. The device according to the invention is particularly intended to allow the protected flow in a closed system, of alcoholic liquid from a reservoir towards the inside of a tube, to be deposited in a reception cone resting on an ocular surface (cornea), surface strictly limited to that of the receiving cone.
