Abstract
Description
La présente invention concerne une canule arthroscopique qui sert commeThe present invention relates to an arthroscopic cannula which serves as
protection de la voie d'accès des instruments utilisés durant la chirurgie arthroscopique. Elle permettrait de réduire le protection of the access path of the instruments used during arthroscopic surgery. It would reduce the
temps opératoire, de faciliter la tache du chirurgien arthroscopiste et d'éviter certaines complications. L'arthroscopie est un domaine de la chirurgie en pleine expansion. La courbe d'apprentissage des chirurgiens va en croissant et les techniques sont de plus en plus performantes. operating time, to facilitate the task of the arthroscopic surgeon and to avoid certain complications. Arthroscopy is a rapidly expanding field of surgery. The surgeons' learning curve is increasing and the techniques are becoming more and more efficient.
Pour accompagner ce progrès le matériel doit être modifié en conséquence. To support this progress, the equipment must be modified accordingly.
Actuellement la canule arthroscopique utilisée remplie la fonction de garder le cite d'introduction ouvert et libre pour le matériel chirurgical à introduire sans laisser l'air o l'eau s'échapper du site opératoire. Certaines possèdent une option d'ancrage aux tissus qu'elles traversent. Pour empêcher l'évasion de l'air ou l'eau à l'extérieur, différents systèmes valve sont conçus, allant de la membrane de latex jusqu'aux valves mécaniques. Plusieurs problèmes dans la canule arthroscopique actuelle consomment l'attention du chirurgien et le temps opératoire qui 15 sont des facteurs importants dans cette pratique chirurgicale: 1- le chirurgien fait toujours attention pour ne pas faire sortir la canule de son conduit, ce qui occupe une partie de son attention. De même en retirant le matériel de la canule, souvent celle ci est entraînée en dehors des tissus, obligeant le chirurgien a l'introduire de nouveau ou bien à la repositionner, ce qui consomme du temps aussi. Currently the arthroscopic cannula used fulfills the function of keeping the introductory site open and free for the surgical material to be introduced without letting air or water escape from the operating site. Some have an option for anchoring the fabrics they pass through. To prevent the escape of air or water outside, different valve systems are designed, ranging from the latex membrane to the mechanical valves. Several problems in the current arthroscopic cannula consume the attention of the surgeon and the operating time which are important factors in this surgical practice: 1- the surgeon is always careful not to get the cannula out of its conduit, which occupies a part of his attention. Similarly by removing the material from the cannula, often the latter is entrained outside the tissue, forcing the surgeon to introduce it again or else to reposition it, which also consumes time.
2- si la canule sort de sa place, le liquide ou le gaz peuvent s'évader dans les tissus, ce qui produit une infiltration des tissus et une diminution de l'espace opératoire visionner. Cet oedème, dans certains cas comme l'arthroscopie de l'épaule, va rendre le reste de l'opération très gênant même très difficile. 2- if the cannula leaves its place, the liquid or the gas can escape into the tissues, which produces an infiltration of the tissues and a reduction in the operating space to be viewed. This edema, in some cases like arthroscopy of the shoulder, will make the rest of the operation very annoying even very difficult.
3-le site d'introduction de la canule est un endroit éffilochable et saignotant ce qui gêne aussi la 25 vision dans un endroit parfois très étroit et oblige le chirurgien a consommer un temps très précieux en nettoyant ce site. 3-the site of introduction of the cannula is a tapered and bleeding place which also impairs vision in a sometimes very narrow place and requires the surgeon to consume very precious time in cleaning this site.
4-la canule est de longueur non modifiable ce qui gène souvent les instruments qui ne sont pas assez long et limite leur utilisation. 4-the cannula is of non-modifiable length which often hinders instruments which are not long enough and limits their use.
5- la mobilité des instruments qui passent par la canule est en partie inversement proportionnelle 30 à sa longueur, souvent la canule limite leur amplitude. 5- the mobility of the instruments which pass through the cannula is partly inversely proportional to its length, often the cannula limits their amplitude.
La canule selon l'invention permet de remédier à ces problèmes cités ci dessus. Elle comporte les caractéristiques suivantes: 1- Une canuleA (1), qui existe en différents diamètres selon le choix du chirurgien. Elle est graduée (1G) d'une façon à permettre au chirurgien d'évaluer l'épaisseur des tissus traversés pour arriver au champ opératoire. Cette graduation permet de choisir une certaine canuleB (3) de façon à obtenir une longueur convenable à l'épaisseur des tissus traversés. La partie proximale de la canuleA peut être sous forme d'un entonnoir (1P) pour permettre au manipulateur d'introduire le montage canuleB-articulateur (10) plus facilement dans la canuleA. The cannula according to the invention overcomes these problems mentioned above. It has the following characteristics: 1- A cannulaA (1), which exists in different diameters according to the choice of the surgeon. It is graduated (1G) in such a way as to allow the surgeon to assess the thickness of the tissues crossed to reach the operating field. This graduation makes it possible to choose a certain cannula B (3) so as to obtain a length suitable for the thickness of the tissues crossed. The proximal part of the cannulaA can be in the form of a funnel (1P) to allow the manipulator to introduce the cannulaB-articulator assembly (10) more easily into the cannulaA.
2- Un obturateur (2) pour permettre à la canuleA de traverser facilement les tissus après l'incision cutanée faite par le chirurgien selon le dessin (6). 2- A shutter (2) to allow the cannulaA to easily pass through the tissue after the skin incision made by the surgeon according to the drawing (6).
3- Une canuleB (3) de diamètre faiblement inférieur à celui de la canuleA, faite en plusieurs 10 longueurs pour s'adapter à l'épaisseur des tissus traversés. Cette longueur est estimée par les graduations sur la canuleA selon le dessin (6 N). La canuleB s'articule avec un articulateur (4) pour être introduite à travers la canuleA. L'articulation entre canuleB et articulateur peut être à travers un filetage interne sur la partie proximale de la canuleB (3 I) et un filetage externe sur la partie distale de l'articulateur (4 F), ou bien sous autres formes d'articulations. 3- A cannula B (3) with a diameter slightly smaller than that of cannula A, made in several lengths to adapt to the thickness of the tissues crossed. This length is estimated by the graduations on the cannula A according to the drawing (6 N). The cannulaB is articulated with an articulator (4) to be introduced through the cannulaA. The articulation between cannula B and articulator can be through an internal thread on the proximal part of the cannula B (3 I) and an external thread on the distal part of the articulator (4 F), or in other forms of articulations .
La partie distale de la canuleB doit comporter un système d'ancrage distal dynamique (3 P) qui peut être sous forme de palmes rectangulaires, triangulaires, en griffes ou autres formes, d'une façon à permettre une manceuvre de compression des tissus traversés. Le système d'ancrage distal doit être conçu de manière à se plier élastiquement dans la canuleA, lors de l'introduction du montage canuleB-articulateur, et de se déplier à la fin du geste (10). L'extraction de la canule 20 suit le chemin inverse (16-17-18-19-20). The distal part of the cannula B must include a dynamic distal anchoring system (3 P) which can be in the form of rectangular, triangular, claw or other shapes, so as to allow compression of the tissues crossed. The distal anchoring system must be designed so as to bend elastically in the cannulaA, during the introduction of the cannulaB-articulator assembly, and to unfold at the end of the gesture (10). The extraction of cannula 20 follows the reverse path (16-17-18-19-20).
4- Un articulateur (4) de diamètre faiblement inférieur à celui de la canuleB avec un filetage distal (4 F), ou autre forme d'articulation, qui permet, selon les dessins (8-9-10-11-12-13), de maintenir la canuleB en place en attendant le geste suivant. 4- An articulator (4) of slightly smaller diameter than that of the cannula B with a distal thread (4 F), or other form of articulation, which allows, according to the drawings (8-9-10-11-12-13 ), keep the cannula B in place while waiting for the next gesture.
5- Un capuchon (5), de diamètre légèrement supérieur à celui de la canuleB, qui s'articule avec 25 la canuleB. Ce capuchon peut contenir une membrane élastique trouée pour faciliter l'introduction des instruments de chirurgie sans fuite de l'eau ou de l'aire (5 E), ou autre système valve. De même, il doit avoir la capacité de laisser la canule B et l'articulateur passer à travers un toit ouvrant (5 C). 5- A cap (5), of diameter slightly larger than that of the cannulaB, which is articulated with the cannulaB. This cap can contain an elastic membrane with holes to facilitate the introduction of surgical instruments without leaking water or air (5 E), or other valve system. Likewise, it must have the capacity to allow the cannula B and the articulator to pass through a sunroof (5 C).
Un deuxième modèle de cette canule est conçu et comporte: 1- une canuleC (21) composée d'une partie proximale (21A), faite pour recevoir une couverture (23), d'un corps fileté dans sa partie externe (21D) et d'un système d'ancrage(21E-24). Le corps fileté permet à un cylindre (21C) de se visser ou de glisser sur toute la longueur du filetage ce qui produit un effet de compression. La partie distale de la canuleC est formée par un système d'ancrage contrôlé proximalement par un cylindre extérieur (21 B). Le système d'ancrage est formé de plusieurs broches (24) qui sont pliées proximalement et distalement dans un plan sagittal de façon à former des griffes. Les broches sont incorporées dans la canule. La rotation des broches faite proximalement a l'aide d'un cylindre (21 B) permet aux griffes de s'écarter de la canule formant ainsi le système d'ancrage distal de la canule (25) (26). A second model of this cannula is designed and comprises: 1- a cannulaC (21) composed of a proximal part (21A), made to receive a cover (23), of a threaded body in its external part (21D) and an anchoring system (21E-24). The threaded body allows a cylinder (21C) to screw or slide over the entire length of the thread which produces a compression effect. The distal part of the cannula C is formed by an anchoring system controlled proximally by an external cylinder (21 B). The anchoring system is formed by several pins (24) which are bent proximally and distally in a sagittal plane so as to form claws. The pins are incorporated into the cannula. The rotation of the pins made proximally using a cylinder (21 B) allows the claws to move away from the cannula thus forming the distal anchoring system of the cannula (25) (26).
2- une couverture (23) qui s'articule avec la partie proximale de la canuleC. Cette couverture contient dans sa partie centrale une membrane élastique (23 E) ou autre système valve. 2- a cover (23) which is articulated with the proximal part of the cannulaC. This cover contains in its central part an elastic membrane (23 E) or other valve system.
3- Un obturateur (22) Les solutions apportées par la présente invention sont les suivantes: 1- le système d'ancrage distal qui comporte des palmes (3 P) ou des griffes (24 A) fixe la canule à l'intérieur des tissus ce qui permet de la laisser en place lors de l'introduction et de l'extraction du matériel chirurgical. 3- A obturator (22) The solutions provided by the present invention are as follows: 1- the distal anchoring system which includes fins (3 P) or claws (24 A) fixes the cannula inside the tissues which allows it to be left in place during the introduction and extraction of surgical material.
2- le système de compression engendré par le vissage du capuchon (13-1415) ou du cylindre 15 (21B) augmente la pression dans les tissus traversés ce qui a un effet hémostatique et diminue l'infiltration des tissus par l'eau ou l'air. De même la compression des tissus va augmenter l'espace opératoire de quelques millimètres ce qui est en effet considérable car on estime souvent l'espace de travail dans certaines régions comme l'épaule de quelques millimètres lui-même. 2- the compression system generated by screwing the cap (13-1415) or the cylinder 15 (21B) increases the pressure in the tissues crossed which has a hemostatic effect and reduces the infiltration of tissues by water or l 'air. Likewise, the compression of the tissues will increase the operating space by a few millimeters, which is indeed considerable since we often estimate the working space in certain regions like the shoulder by a few millimeters itself.
3- l'ancrage distal et la compression ajoutent une stabilité à la canule ce qui diminue les 20 effilochages récurrents au niveau de l'extrémité distale. 3- distal anchoring and compression add stability to the cannula which reduces recurrent fraying at the distal end.
4- la modularité de la canule et les différentes tailles de la canuleB, permettent de gagner de la longueur pour les instruments et de l'amplitude dans le champ de travail. 4- the modularity of the cannula and the different sizes of the cannulaB, allow to gain length for the instruments and amplitude in the field of work.
L'installation en place de la canuleB se fait selon les étapes suivantes: 25 -Incision cutanée. The installation in place of the cannula B is carried out according to the following steps: 25 - Skin incision.

-Introduction du capuchon à toit ouvert (12) et l'articuler avec la canuleB (13). -Introduction of the cap with open roof (12) and articulate it with the cannula B (13).
-Dévissage de larticulateur et fermeture du toit (14). Le vissage du capuchon se fait à l'inverse de larticulateur ce qui permet de serrer bien et d'obtenir la compression demandée. -Unscrewing the articulator and closing the roof (14). The screwing of the cap is done in reverse of the articulator which allows to tighten well and to obtain the required compression.
-L'ablation de la canule ou son déplacement a un autre niveau se fait par le chemin inverse selon les dessins (16-17-18-19-20). -The ablation of the cannula or its movement to another level is done by the reverse path according to the drawings (16-17-18-19-20).
L'installation en place de la canuleC se fait selon les étapes suivantes: -Incision cutanée. The installation in place of the cannulaC is done according to the following steps: - Skin incision.
