Description

DISPOSITIF POUR LA MISE EN PLACE DANS UNE VEINE D'UN TUBEDEVICE FOR PLACING A TUBE INTO A VEIN
CATHETER.CATHETER.
L'invention concerne un dispositif comportant une gaine tubulaire associée à un tube dit dilatateur, pour la mise en place dans une veine d'un tube cathéter après introduction du dispositif par la méthode dite de Seldinger.The invention relates to a device comprising a tubular sheath associated with a so-called dilator tube, for placing a catheter tube in a vein after introduction of the device by the so-called Seldinger method.
Cette méthode implique les opérations suivantes :This method involves the following operations:
1) Ponction de la veine avec une aiguille ;1) Puncture the vein with a needle;
2) Introduction d'un guide métallique dans la veine au travers de 1 ' aiguille de ponction ; 3) Retrait de l'aiguille ;2) Introduction of a metal guide into the vein through the puncture needle; 3) Removal of the needle;
4) Introduction par-dessus le guide métallique d'un ensemble constitué par une gaine enfilée sur un tube dilatateur ;4) Introduction over the metal guide of an assembly constituted by a sheath threaded on a dilator tube;
5) Retrait du dilatateur et du guide, la gaine restant en place ;5) Removal of the dilator and guide, the sheath remaining in place;
6) Introduction du cathéter dans la gaine ;6) Introduction of the catheter into the sheath;
7) Retrait de la gaine.7) Removing the sheath.
Le problème se pose de faciliter l'insertion de la gaine dans le corps et son extraction afin de réduire les risques de traumatisme.The problem arises of facilitating the insertion of the sheath into the body and its extraction in order to reduce the risks of trauma.
Diverses solutions à ce problème sont décrites dans les publications US 5 499 975, US 5 098 393, WO 99/21605, EP 0 792 660.Various solutions to this problem are described in the publications US 5,499,975, US 5,098,393, WO 99/21605, EP 0 792 660.
La publication FR-A-2439591 décrit d'autre part une telle gaine tubulaire (5) , qui présente sur toute sa longueur une fente (6) élastique, dont l'extrémité distale (7) a été émoussée et qui est enfilée sur un tube dilatateur (1) dont l'extrémité distale (3) est effilée.The publication FR-A-2439591 describes on the other hand such a tubular sheath (5), which has over its entire length an elastic slot (6), the distal end (7) of which has been blunted and which is threaded on a dilator tube (1) whose distal end (3) is tapered.
L'expression "fente élastique" signifie que les lèvres de la fente peuvent s'écarter l'une de l'autre, mais reviennent l'une vers l'autre quand la cause qui a provoqué cet écartement a cessé. Pour faciliter le passage à travers la peau et la paroi de la veine, les extrémités distales du dilatateur et de la gaine subissent un traitement : le dilatateur est effilé pour obtenir une pente dont le diamètre distal est le plus voisin du diamètre du guide. la gaine est émoussée pour l'ajuster sur le diamètre extérieur du dilatateur.The expression "elastic slit" means that the lips of the slit can deviate from each other, but return to each other when the cause which has caused this separation has ceased. To facilitate the passage through the skin and the wall of the vein, the distal ends of the dilator and the sheath undergo a treatment: the dilator is tapered to obtain a slope whose distal diameter is closest to the diameter of the guide. the sheath is blunt to adjust it to the outside diameter of the dilator.
Sur la figure 1 du dessin joint qui reproduit la figure 1 de cette publication, la gaine et le dilatateur sont représentés séparés tandis que sur la figure 2 du dessin qui reproduit la figure 2 de la publication, la gaine est enfilée sur le dilatateur. L'émoussage de la gaine est une opération délicate. Il faut en effet conserver un plat distal (marche) pour éviter le retournement de la gaine au passage des tissus .In FIG. 1 of the attached drawing which reproduces FIG. 1 of this publication, the sheath and the dilator are shown separately while in FIG. 2 of the drawing which reproduces FIG. 2 of the publication, the sheath is threaded on the dilator. Blunting the sheath is a delicate operation. It is indeed necessary to keep a distal dish (step) to avoid the reversal of the sheath in the passage of tissue.
Il subsiste donc une sensation de butée au passage des tissus et de la veine qui se traduit par un traumatisme.There therefore remains a feeling of abutment in the passage of the tissues and of the vein which results in a trauma.
La présente invention vise à éviter ces inconvénients .The present invention aims to avoid these drawbacks.
On y parvient, selon la présente invention, avec un dispositif qui comprend une gaine qui présente une partie courante cylindrique et qui est fendue sur toute sa longueur par une fente élastique, cette gaine étant enfilée sur un tube dilatateur qui présente une partie courante cylindrique et une extrémité distale effilée, et qui présente les particularités suivantes :This is achieved, according to the present invention, with a device which comprises a sheath which has a cylindrical running part and which is split over its entire length by an elastic slot, this sheath being threaded on an dilator tube which has a cylindrical running part and a tapered distal end, which has the following features:
- l'extrémité distale du tube est raccordée à la partie courante du tube par un épaulement en saillie sur cette partie courante, - la partie courante cylindrique de la gaine aboutit à une tranche distale qui est évasée vers l'avant, - l' épaulement du tube épouse la tranche distale de la gaine .the distal end of the tube is connected to the current part of the tube by a shoulder projecting from this current part, the cylindrical current part of the sheath ends in a distal section which is flared forward, - the shoulder of the tube follows the distal edge of the sheath.
Du fait de cette combinaison de caractéristiques, le passage des tissus se fait sans butée et donc sans traumatisme.Due to this combination of characteristics, the passage of the tissues is done without abutment and therefore without trauma.
Lors du retrait du dilatateur, la fente de la gaine s ' ouvre pour laisser passer 1 ' épaulement du dilatateur et reprend sa forme initiale (fermée) après retrait complet.When removing the dilator, the sheath opening opens to allow the shoulder of the dilator to pass and resumes its initial (closed) shape after complete withdrawal.
On décrira ci-après un exemple de réalisation de l'invention, en référence aux figures du dessin joint sur lequel :An exemplary embodiment of the invention will be described below, with reference to the figures in the accompanying drawing in which:
- les figures 1 et 2, déjà décrites ci-dessus, reproduisent les figures 1 et 2, respectivement, de la publication précitée ; - la figure 3 est une coupe axiale d'un exemple de réalisation d'un dispositif comportant une gaine et un dilatateur selon la présente invention.- Figures 1 and 2, already described above, reproduce Figures 1 and 2, respectively, of the above publication; - Figure 3 is an axial section of an exemplary embodiment of a device comprising a sheath and a dilator according to the present invention.
- la figure 4 montre une élévation (figure 4A) et est une coupe (figure 4B) des extrémités distales de la gaine et du dilatateur du dispositif de 1 ' invention, etFIG. 4 shows an elevation (FIG. 4A) and is a section (FIG. 4B) of the distal ends of the sheath and of the dilator of the device of the invention, and
- les figures 5 et 6 sont des vues agrandies respectivement de 1 ' élévation et de la coupe de la figure 4, et - la figure 7 est une vue en élévation correspondant à celle de la figure 5 mais pendant le retrait du dilatateur. Le dispositif représenté sur les figures 3 à 6 est constitué : - d'une gaine tubulaire cylindrique (11) fendue longitudinalement en (12) sur toute sa longueur et munie à son extrémité proximale (c'est-à-dire qui sera proche du manipulateur) d'une ailette (13) destinée à faciliter sa prise en main. La gaine est réalisée, de façon en soi connue, dans un matériau tel que la fente puisse s'ouvrir sous l'effet du passage à l'intérieur de la gaine d'un élément de diamètre externe supérieur au diamètre interne, de la gaine, et se refermer d'elle-même après retrait de cet élément, ce que 1 ' on a appelé ci-avant gaine à fente élastique.- Figures 5 and 6 are enlarged views respectively of one elevation and of the section of Figure 4, and - Figure 7 is an elevational view corresponding to that of Figure 5 but during the withdrawal of the dilator. The device represented in FIGS. 3 to 6 consists of: - a cylindrical tubular sheath (11) split longitudinally at (12) over its entire length and provided at its proximal end (that is to say which will be close to the manipulator) of a fin (13) intended to facilitate its handling. The sheath is made, in a manner known per se, in a material such that the slot can open under the effect of passage inside the sheath of an element with an external diameter greater than the internal diameter of the sheath, and closing itself after removal of this element, what has been referred to above as sheath elastic slit.
Par exemple, la gaine est un tube en polyuréthane dont les diamètres internes/externes sont compris dans les gammes 1,5 / 5,5 mm. - d'un tube dilatateur cylindrique (14) muni d'une embase proximale de raccordement (15) et dont le bout distal (16) est effilé. Ce tube est en résine de synthèse, par exemple en polypropylène . Conformément à l'invention, l'extrémité distale (16) du tube dilatateur est raccordée à la partie courante cylindrique (14) du tube par un épaulement (17) en saillie sur cette partie courante.For example, the sheath is a polyurethane tube whose internal / external diameters are included in the 1.5 / 5.5 mm ranges. - a cylindrical dilator tube (14) provided with a proximal connection base (15) and whose distal end (16) is tapered. This tube is made of synthetic resin, for example polypropylene. According to the invention, the distal end (16) of the dilator tube is connected to the cylindrical running part (14) of the tube by a shoulder (17) projecting from this running part.
La forme de cet épaulement peut être quelconque mais on donne la préférence à une forme tronconique dont la section droite diminue de l'avant vers l'arrière, comme c'est le cas dans l'exemple représenté.The shape of this shoulder can be any, but preference is given to a frustoconical shape whose cross section decreases from front to back, as is the case in the example shown.
La tranche (18) de l'extrémité distale de la gaine (11) a une forme tronconique évasée vers l'avant en rapport avec celle de l' épaulement de façon à épouser 1 ' épaulement . Le diamètre externe de la partie courante du tube (14) est choisi sensiblement égal au diamètre intérieur (dl) de la gaine (11) pour que la gaine soit enfilée sur le tube avec un certain frottement tandis que le diamètre (d2) du tube au sommet de l' épaulement est choisi égal ou légèrement supérieur au diamètre extérieur (d3) de la gaine pour que la gaine ne déborde pas extérieurement de 1 ' épaulement . The edge (18) of the distal end of the sheath (11) has a frustoconical shape flared towards the front in relation to that of the shoulder so as to match the shoulder. The external diameter of the current part of the tube (14) is chosen to be substantially equal to the internal diameter (dl) of the sheath (11) so that the sheath is threaded onto the tube with a certain friction while the diameter (d2) of the tube at the top of the shoulder is chosen equal to or slightly greater than the outside diameter (d3) of the sheath so that the sheath does not project outwardly from the shoulder.
