Abstract
Description
La présente invention a pour objet un drain, destiné notamment à être placé dans un uretère pour maintenir le drainage du rein vers la vessie. The present invention relates to a drain, intended in particular to be placed in a ureter to maintain drainage from the kidney to the bladder.
On c-onnait déjà des drains destinés à un tel usage, no'cam- ment par la demande de brevet français n0 2 421 625.Drains intended for such use were already known, in particular by French patent application No. 2 421 625.
Ce document décrit une sonde formant cathéter uretéral, constituée d'un fin tube souple, à parois perforées, dont les extrémités sont recourbées en formes de crochets en vue d'éviter la migration de la sonde au cours de son utilisa t ion. This document describes a probe forming a ureteral catheter, consisting of a thin flexible tube, with perforated walls, the ends of which are curved in the shape of hooks in order to avoid migration of the probe during its use.
Ce type de sonde connu convient bien pour une utilisation permanente, c'est à dire lorsque la sonde est mise en place (par cystoscopie) de manière définitive sur un patient.This type of known probe is well suited for permanent use, that is to say when the probe is placed (by cystoscopy) permanently on a patient.
Par contre, lorsque la sonde connue n'est destinée qu'S un usage temporaire elle présente l'inconvénient de ndoessiter, pour son retrait, une seconde opération de cystoscopie, avec tous les désagréments qu'une telle opération implique pour le patient.On the other hand, when the known probe is only intended for temporary use, it has the drawback of requiring, for its removal, a second cystoscopy operation, with all the inconvenience that such an operation implies for the patient.
C'est pourquoi l'invention a pour objet un drain uretérel dont la mise en place se fait de manière connue, meis dont le retrait ne nécessite pas une intervention cystoscopique. This is why the invention relates to a ureteral drain, the installation of which is carried out in a known manner, but the removal of which does not require cystoscopic intervention.
A cet effet le drain selon l'invention se caractérise essentiellement en ce qu'il est muni de moyens permettant d'extr- cer une traction sur une de ses extrémités, depuis l'exté- rieur du corps du patient.To this end, the drain according to the invention is essentially characterized in that it is provided with means making it possible to extract traction on one of its ends, from outside the patient's body.
La description qui va suivre en regard des dessins annexes fera mieux comprendre l'invention.The description which follows with reference to the accompanying drawings will make the invention better understood.
La figure 1 représente un drain 1 selon l'invention, tel qu'il se présente avant son implantation sur un patient.FIG. 1 represents a drain 1 according to the invention, as it appears before its implantation on a patient.
La figure 2 est une vue en coupe du drain 1 placé dans I tère d'un patient, entre la vessie et le bassinet d~un rein.Figure 2 is a sectional view of the drain 1 placed in I ter of a patient, between the bladder and the pelvis of a kidney.
Le drain 1 est constitué d'un tube 2 en matière souple dont une extrémité fermée 3 est, à l'état de repos, recourbée en forme de crochet. L'autre extrémité est munie de moyens 5 permettant d'exercer une traction sur ladite extrémité.The drain 1 consists of a tube 2 of flexible material, one closed end 3 of which, in the rest state, is bent in the shape of a hook. The other end is provided with means 5 making it possible to exert traction on said end.
Ces moyens 5 sont constitués par exemple par un lien rendu solidaire de l'extrémité 4 par une ligature et/ou par une soudure.These means 5 are constituted for example by a link made integral with the end 4 by a ligature and / or by a weld.
Lorsque le drain 1 est en place sur un patient (figure 2), son extrémité 4 se trouve à l'intérieur de la vessie et le lien 5 s'étend par l'urètre de la vessie jusqu'à l'extérieur du méat urinaire où il peut être fixé par exemple par un morceau de bande adhésive 6.When the drain 1 is in place on a patient (Figure 2), its end 4 is inside the bladder and the link 5 extends through the urethra of the bladder to the outside of the urinary meatus where it can be fixed for example by a piece of adhesive tape 6.
Le drain ayant été mis en place de manière connue, c'est à dire après avoir été rigidifié par enfilement d'un mandrin métallique flexible, puis introduit par cystoscopie, on voit que, pour son retrait, il suffit de tirer sur le lien 5.The drain having been put in place in a known manner, that is to say after having been stiffened by threading a flexible metal mandrel, then introduced by cystoscopy, it can be seen that, for its removal, it suffices to pull on the link 5 .
Le lien 5 peut être simple, c'est à dire constitué d'un fil solidaire par une extrémité 5' de l'extrémité 4 du drain, l'autre extrémité 5" étant libre (variante non illustrée par la figure 1).The link 5 can be simple, that is to say made up of a wire secured by one end 5 ′ to the end 4 of the drain, the other end 5 ″ being free (variant not illustrated in FIG. 1).
Il peut cependant être avantageux que le lien 5 soit double, comme l'illustre la figure 1, de manière que chacune de ses extrémités 5'et 5" solidaires de l'extrémité 4 soit symétrique de l'autre par rapport à un plan passant par l'axe du drain.It may however be advantageous for the link 5 to be double, as illustrated in FIG. 1, so that each of its 5 ′ and 5 ″ ends integral with the end 4 is symmetrical with the other with respect to a passing plane by the axis of the drain.
Un tel agencement du lien 4 permet, par action simultanée sur les deux brins 5' et 5", d'exercer une traction dans la direction voulue, sans risquer de voir l'extrémité 4 se courber ou dévier dans une mauvaise direction.Such an arrangement of the link 4 allows, by simultaneous action on the two strands 5 'and 5 ", to exert traction in the desired direction, without risking seeing the end 4 bending or deviating in a wrong direction.
Par ailleurs, l'action alternée sur l'un des brins 5' et 5" puis sur l'autre permet de donner à l'extrémité 4 du drain un mouvement ondulant facilitant son glissement.Furthermore, the alternating action on one of the strands 5 ′ and 5 "then on the other makes it possible to give the end 4 of the drain an undulating movement facilitating its sliding.
Le brin 5' (lien simple) ou les deux brins 5' et 5" (lien double) doivent bien entendu autre fixés aussi près que possible de l'extrémité 4. Ils peuvent l'entre par exemple au moyen d'une ligature 6, ou de préférence de deux ligatures 6 et 7, noyées dans le revêtement protecteur du drain. Ils peuvent également être soudés sur l'extrémité 4, ou encore fixés par extrusion autour de ladite extrémité.The 5 'strand (single link) or the two 5' and 5 "strands (double link) must, of course, be fixed as close as possible to the end 4. They can enter it for example by means of a ligature 6 , or preferably two ligatures 6 and 7, embedded in the protective covering of the drain, they can also be welded to the end 4, or even fixed by extrusion around said end.
Enfin, dans le cas du lien double, les deux brins 5' et 5" constituent avantageusement un seul lien 5, c'est à dire qu'ils forment une boucle, représentée sur la figure 1, dans laquelle le praticien pourra passer un doigt pour exercer une traction, lors du retrait du drain.Finally, in the case of the double link, the two strands 5 ′ and 5 "advantageously constitute a single link 5, that is to say that they form a loop, represented in FIG. 1, in which the practitioner can pass a finger to exert traction, when removing the drain.
Le drain selon l'invention peut comporter éventuellement des particularités déjà connues pour d'autres types de sondes.The drain according to the invention may possibly include features already known for other types of probes.
Ainsi il peut présenter, sur tout ou partie de sa longueur, des perforations 8 faisant communiquer l'intérieur du drain avec l'extérieur, pour améliorer le drainage.Thus it can have, over all or part of its length, perforations 8 communicating the inside of the drain with the outside, to improve drainage.
Il peut également présenter divers marquages, par exemple des graduations de longueur destinées à renseigner le praticien au cours de l'opération d'implantation ou de retrait, ou encore une ligne radio-opaque permettant de localiser le drain par radioscopie.It can also have various markings, for example length graduations intended to inform the practitioner during the implantation or removal operation, or even a radiopaque line making it possible to locate the drain by radioscopy.
Exemple de réalisation. Example of realization.
Cet exemple est celui d'un mode de réalisation préféré. Il
ne doit pas être considéré comme une limitation à l'étendue
de l'invention.This example is that of a preferred embodiment. he
should not be considered a limitation on the scope
of the invention.
Un drain selon l'invention est constitué d'un tube (2) fin
fermé à une extrémité (3), en une matière souple, physiologiquement acceptable et résistante à la traction, par exemple en silicone, en polyuréthane ou en polychiorure de vinyle. Son diamètre extérieur est d'environ 3 me, son diamètre intérieur est d'environ 1,3 mm et sa longueur totale, dépendant de la taille du patient, peut aller de 25 à 45 cm à l'état étiré.A drain according to the invention consists of a thin tube (2)
closed at one end (3), in a flexible material, physiologically acceptable and resistant to traction, for example silicone, polyurethane or polyvinyl chloride. Its outside diameter is about 3 me, its inside diameter is about 1.3 mm and its total length, depending on the size of the patient, can range from 25 to 45 cm in the stretched state.
A l'état de repos, l'extrémité 3 s'enroule sur elle-même en un crochet pratiquement fermé dont le diamètre de courbure
est d'environ 25 me. In the state of rest, the end 3 is wound on itself in a practically closed hook whose diameter of curvature
is about 25 me.
A l'outre e-xtJémitd (4) la drain porte un lien (5) constitué
dun fil souple et rdsistant, par exempte en fibre de poly
amide ou de polyester, dont les deux extrémités (5 et 5") forment des ligatures (6, 7) autour de l'extrémité 4.In addition to e-xtJémitd (4) the drain carries a link (5) consisting
of a flexible and resistant thread, for example in poly fiber
amide or polyester, the two ends (5 and 5 ") of which form ligatures (6, 7) around the end 4.
Celles ci-sont noyées dans un vernis souple afin d'être rendues plus lisses.These are embedded in a flexible varnish to be made smoother.
La longueur du lien (5) dépend également de la taille du patient. Elle peut être par exemple de 60 à 80 cm (longueur totale du lien, c'est à dire que la boucle elle-même a une longueur deux fois moindre lorsqu'elle est étirée). The length of the link (5) also depends on the size of the patient. It can be for example from 60 to 80 cm (total length of the link, that is to say that the loop itself has a length that is half the length when it is stretched).
