Abstract

Device for destroying varicose veins of the lower limbs in man. It consists of a tube (1) which is open at both ends and which we will refer to as the cylinder, the latter having on the outer part of one of its ends a dozen or so small roughened areas (3) each of approximately half a millimetre. A solid rod (2) slides easily in the cylinder and will be referred to as the plunger. One of the ends of this plunger is continued via a nylon thread (4) on which there is a ball-shaped bulge (5). The small roughened areas are intended to destroy the inner part of the vein, called the epithelium or intima. Inside the cylinder, the part left free by the nylon thread will be filled by a sclerosing liquid intended to destroy the varicose vein. The device according to the invention is intended in particular for destroying varicose veins of the lower limbs in man.

Description

La présente inventioh concerne un dispositif destiné à détruire les varices des membres inférieurs chez l'homme. The present invention relates to a device intended to destroy varicose veins of the lower limbs in humans.

Actuellement la destruction médicale des varices repose sur l'injection de produits sclérosants à l'aide d'une seringue. Elle n'est pas traumatisantet elle est ambulatoire,mais pas toua ours efficacefoar le produit sclérosant injecté se trouve dilué dans le sang des varices. D'autre part et qui est trés important, le produit sclérosant n'agit qu'aux endroits ou ltendothélium ou intima présente des solutions de continuité
Le dispositif selon liinvention permet de remédier à ces inconvénients.
Currently the medical destruction of varicose veins is based on the injection of sclerosing products using a syringe. It is not traumatic and it is ambulatory, but not always effective because the injected sclerosing product is diluted in the blood of varicose veins. On the other hand and which is very important, the sclerosing product only acts in places where the endothelium or intima presents solutions of continuity
The device according to the invention overcomes these drawbacks.

Il comporte
Un tube en plastique semi rigide (1) que nous appellerons cylindre qui présente à l'une de ses extrémités et seulement à l'extérieur une douzaine (3)de petites aspérités d'un demi millimètre chacune et dirigées vers l'autre extrémité du cylindre. les aspérités peuvent autre de la matière même du cylindre ou faites de petites pièces métalliques serties dans l'épaisseur du cylindre et sortant de celui ci d'un demi millimètre
Une tige pleine en plastique semi rigide également que nous apptélerons piston , qui sera introduit dans le tube 1 et qui doit coulisser facilement dans ce tube comme le fait le piston d'une seringue.Ce piston sera plus long que le cylindre d'une dizaine de centimétres. Les deux extrémités du piston sont effilées pour permettre une introduction facile dans le cylindre. Une des extrémités du piston se prolonge par un fil de nylon (4). Sur ce fil de nylon se trouve un renflement en forme de boule donc en nylon mais qui peut être également en métal et dont le rôle est de fermer hermétiquement l'extrémi- té du cylindre .Cette boule de nylon viendra se placer i l'extrémité du tube du coté des aspérités.La longueur da fil de nylon de son insertion au piston Jusquà la boule doit être inférieur de dix centimétres environ de la longueur du cylindre0 Le filde nylon de par sa nature pesséde une c ertaine élasticité.
It comprises
A semi rigid plastic tube (1) which we will call a cylinder which has at one of its ends and only outside a dozen (3) of small asperities of half a millimeter each and directed towards the other end of the cylinder. the asperities can other of the same material of the cylinder or made of small metallic parts crimped in the thickness of the cylinder and leaving this one of half a millimeter
A solid rod in semi rigid plastic also which we will call piston, which will be introduced into tube 1 and which must slide easily in this tube as does the piston of a syringe. This piston will be longer than the cylinder by ten of centimeters. The two ends of the piston are tapered to allow easy introduction into the cylinder. One end of the piston is extended by a nylon thread (4). On this nylon thread is a bulge in the form of a ball therefore made of nylon but which can also be made of metal and whose role is to hermetically seal the end of the cylinder. This nylon ball will be placed at the end of the tube on the side of the roughness. The length of nylon thread from its insertion into the piston Up to the ball must be approximately ten centimeters less than the length of the cylinder.

Le piston sera introduit dans le cylindre par l'extrémité ou il n'y a pas de fil de nylon et dans l'extrémité du cylindre ou se trouvent les aspérités. The piston will be introduced into the cylinder by the end where there is no nylon thread and in the end of the cylinder where the roughness is.

Un petit repère (6) gravé sur le piston indiquera lorsqu'vil arrivera à l'extrémité du cylindre opposé aux aspérités que la boule est bien appliquée sur l'extrémité du cylindre et que le fil de nylon est correctement tendu. A small mark (6) engraved on the piston will indicate when it arrives at the end of the cylinder opposite to the rough edges that the ball is well applied on the end of the cylinder and that the nylon thread is correctly stretched.

L'extrémité du cylindre ou se trouvent les aspérités, avec le piston à l'intérieur , sera plongée dans un récipient ou se trouve le liquide sclérosant qui aura été déterminé à l'avance en fonction de chaque malade. The end of the cylinder where the asperities are, with the piston inside, will be immersed in a container or there is the sclerosing liquid which will have been determined in advance according to each patient.

Le piston est alors tiré vers le haut et le liquide sclérosant et le fil de nylon montent dans le cylindre .La boule de nylon se trouvant sur le fil ayant un diamétre légèrement supérieur au diamètre interne du cylindre viendre fermer celuici hermétiquement . L'éiasticité du fil de nylon permet en tirant sur le piston de faire affleurer le repére (6) avec l1ex- trémité du cylindre et à ce moment le piston est bloqué dans le cylindre par une petite pince.The piston is then pulled upwards and the sclerosing liquid and the nylon thread go up into the cylinder. The nylon ball being on the thread having a diameter slightly larger than the internal diameter of the cylinder comes to close it tightly. The elasticity of the nylon thread makes it possible by pulling on the piston to make the mark (6) flush with the end of the cylinder and at this time the piston is locked in the cylinder by a small clamp.

La veine ayant été mise à nu , on procède alors à l'introduction de l'appareil , coté avec rugosités et boule de nylon , dans celle ci par une petite ouverture et on progresse ainsi jusqunà la cheville si possible. The vein having been exposed, we then proceed to the introduction of the device, dimensioned with roughness and nylon ball, in this one by a small opening and we thus progress to the ankle if possible.

A cd moment une bande compressive collante est posée d e la cheville Jusqu'en haut de la cuisse et la varice se trouve vidée de son sang. On enlève la pince qui bloquait piston et cylindre. On maintient la boule de trouvent alors à la cheville entre deux doigts au travers de la peau et on enlève totalement et doucement le cylindre en le tirant hors de la veine et en lui imprimant de petits mouvements de rotation dans les deux sens . Par les as pérîtes l'endothélium a été détruit en de nombreux endroits et sur toute la longueur de la veine. En enlevant le cylindre , leliquide contenu dans celui ci se trouve déposé dans la veine 1vide de sanS 1d'une façon uniforme réguliére,et sur toute la longueur.de celle ci.At this moment a sticky compressive band is placed from the ankle to the top of the thigh and the varicose vein is emptied of its blood. We remove the clamp that blocked piston and cylinder. The ball is then held at the ankle between two fingers through the skin and the cylinder is completely and gently removed by pulling it out of the vein and giving it small rotational movements in both directions. By the aces perished the endothelium was destroyed in many places and along the entire length of the vein. By removing the cylinder, the liquid contained therein is deposited in the empty vein 1 without sanS 1 in a uniform regular fashion, and over the entire length thereof.

La boule de nylon et le fil seront dans un deuxiéme temps en tirant sur le piston donc sur le filt retirés de la veine
Ce dispositif selon l'invention est particuliérement destiné à la destruction des varices des mmebres inférieurs chez l'homme
The nylon ball and the thread will be in a second step by pulling on the piston therefore on the filt removed from the vein
This device according to the invention is particularly intended for the destruction of varicose veins of the lower limbs in humans
