Description

PROTHESE AORTIQUE AVEC DISPOSITIF RAPIDE DE CONNEXION A LA CIRCULATION EXTRA-CORPORELLE AORTIC PROSTHESIS WITH QUICK DEVICE FOR CONNECTION TO EXTRA-BODY CIRCULATION
La présente invention a pour objet une prothèse aortique avec dispositif rapide de connexion a la circulation extra-corporelle.The present invention relates to an aortic prosthesis with rapid device for connection to the extra-corporeal circulation.
Elle se rapporte d'une manière générale au domaine de la chirurgie artérielle et plus particulièrement aux interventions visant au remplacement par une prothèse d'une partie ou de la totalité de l'aorte.It relates generally to the field of arterial surgery and more particularly to interventions aimed at replacing part or all of the aorta with a prosthesis.
Actuellement, lorsqu'il faut remplacer l'aorte ascendante ou une autre partie de l'aorte par un tube prothétique et que l'on veut, au cours de cette intervention, insérer la ligne de perfusion artérielle de la circulation extra-corporelle dans la prothèse afin d'assurer une injection du sang dans le sens anterograde, il faut préalablement pratiquer un trou au bistouri dans la prothèse pour y introduire une canule puis assurer l'étanchéité et solidariser la canule avec la prothèse et enfin connecter cette canule au tuyau artériel de la Circulation Extra-Corporelle (CEC).Currently, when it is necessary to replace the ascending aorta or another part of the aorta with a prosthetic tube and we want, during this intervention, to insert the arterial perfusion line of the extra-corporeal circulation in the prosthesis to ensure anterograde blood injection, you must first make a hole in the scalpel in the prosthesis to introduce a cannula then seal and secure the cannula with the prosthesis and finally connect this cannula to the arterial tube of Extra-Bodily Circulation (CEC).
Cette technique nécessite une durée d'intervention plus importante et présente l'inconvénient d'entraîner des difficultés pour assurer une bonne étanchéité.This technique requires a longer intervention time and has the drawback of causing difficulties in ensuring good sealing.
En outre, à la fin de l'intervention, lors de l'ablation de la canule, il faut assurer l'hémostase en occluant l'orifice qui a été pratiqué dans la prothèse ce qui, souvent, pose des problèmes.In addition, at the end of the intervention, when the cannula is removed, hemostasis must be ensured by occluding the orifice which has been made in the prosthesis, which often poses problems.
La présente invention a pour objectif de remédier à cet état de choses. Elle permet en effet de réaliser un dispositif sans fuite permettant une connexion rapide avec le tube artériel de la circulation extra-corporelle et facile à occlure à la fin de l'intervention.The present invention aims to remedy this state of affairs. It makes it possible to produce a leak-free device allowing rapid connection with the arterial tube of the extra-corporeal circulation and easy to occlude at the end of the intervention.
Il est constitué d'un tube prothétique équipé d'un conduit de perfusion implanté latéralement et pourvu à son extrémité d'un connecteur rapide destiné à être raccordé à la tubulure artérielle d'un système de circulation extra-corporelle.It consists of a prosthetic tube fitted with a laterally implanted infusion pipe and provided at its end with a quick connector intended to be connected to the arterial tubing of an extracorporeal circulation system.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une forme de réalisation conforme à la présente demande : la figure 1 représente le dispositif de prothèse aortique avant implantation, la figure 2 montre un coeur préparé pour recevoir le dispositif de la figure 1 , une pompe de circulation extra-corporelle injectant le sang provenant du coeur vers l'artère fémorale, la figure 3 représente le même coeur avec la prothèse mise en place et connectée à la circulation extra-corporelle et la figure 4 est une vue du coeur à la fin de l'intervention, après sectionnement et suture du conduit de perfusion.In the accompanying drawings, given by way of nonlimiting example of an embodiment in accordance with the present application: FIG. 1 represents the aortic prosthesis device before implantation, FIG. 2 shows a heart prepared to receive the device of the Figure 1, an extracorporeal circulation pump injecting blood from the heart to the femoral artery, Figure 3 shows the same heart with the prosthesis in place and connected to the extracorporeal circulation and Figure 4 is a view of the heart at the end of the intervention, after sectioning and suturing of the infusion line.
Le dispositif, figures 1 , 3 et 4, est formé d'un tube prothétique 1 comportant un conduit de perfusion 2 permettant l'injection du sang durant la mise en place de la prothèse (figure 1).The device, FIGS. 1, 3 and 4, is formed by a prosthetic tube 1 comprising a perfusion conduit 2 allowing the injection of blood during the positioning of the prosthesis (FIG. 1).
Le tube prothétique 1 est du type standard actuellement utilisé dans le remplacement de l'aorte ascendante ou de la crosse aortique 3.The prosthetic tube 1 is of the standard type currently used in the replacement of the ascending aorta or the aortic arch 3.
Le conduit de perfusion 2 consiste en un tube plus petit suturé en dérivation sur le corps de la prothèse, et à l'extrémité duquel est serti un connecteurThe infusion line 2 consists of a smaller tube sutured bypass on the body of the prosthesis, and at the end of which is crimped a connector
4 permettant un raccordement facile et rapide avec la tubulure artérielle de la circulation extra-corporelle, la section du conduit étant égale ou proche de celle du tube artériel de cette dernière.4 allowing easy and quick connection with the arterial tubing of the extra-corporeal circulation, the section of the duct being equal to or close to that of the arterial tube of the latter.
L'intervention se déroule de la manière suivante :The intervention proceeds as follows:
Il est tout d'abord procédé à la mise en place d'un ensemble de circulation extra-corporelle constitué d'une pompe 5, d'une canule 6 permettant de prélever le sang dans le coeur 7 et d'une tubulure artérielle double comportant une première branche 8 d'injection s'insérant dans l'artère fémorale 9 et une secondes branche 10 destinée à assurer une injection du sang dans le sens anterograde. La partie de l'aorte 3 à remplacer est enlevée (figure 2). Le tube prothétique 1 est mis en place et suturé à l'aide d'un fil 11 de type connu et le conduit de perfusion 2 de la prothèse est raccordé à la seconde branche 10 de la tubulure artérielle. L'injection de sang se fait maintenant par la prothèse, la circulation vers l'artère fémorale 8 étant alors interrompue au moyen d'un clamp 12 (figure 3).First of all, an extracorporeal circulation assembly is put in place, consisting of a pump 5, a cannula 6 making it possible to draw blood from the heart 7 and a double arterial tubing comprising a first branch 8 of injection inserted into the femoral artery 9 and a second branch 10 intended to ensure an injection of blood in the anterograde direction. The part of aorta 3 to be replaced is removed (Figure 2). The prosthetic tube 1 is put in place and sutured using a wire 11 of known type and the perfusion pipe 2 of the prosthesis is connected to the second branch 10 of the arterial tubing. The blood injection is now made by the prosthesis, the circulation towards the femoral artery 8 being then interrupted by means of a clamp 12 (FIG. 3).
A la fin de l'intervention, on procède à l'ablation du conduit de perfusion 2, qui est conçu pour pouvoir être obturé rapidement et aisément à l'aide d'une ligature 13 ou d'un autre moyen, puis sectionné (figure 4).At the end of the procedure, the infusion line 2 is removed, which is designed to be able to be closed quickly and easily using a ligature 13 or other means, then sectioned (figure 4).
Le dispositif décrit présente de nombreux avantages par rapport aux techniques connues. Il est rapide à connecter, étanche et facile à enlever, l'hémostase étant facile à réaliser puisqu'il s'agit d'une ligature simple.The device described has many advantages over known techniques. It is quick to connect, waterproof and easy to remove, the hemostasis being easy to perform since it is a simple ligature.
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 systèmes 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 systems.
