REVENDICATIONS 1. Instrument chirurigcal pour le nettoyage d'une cavité, caractérisé en ce qu'il comprend deux éléments tubulaires emboîtés coaxialement pour délimiter entre eux un passage annulaire, l'élément tubulaire intérieur dépassant de l'extrémité correspondante de l'élément tubulaire extérieur qui est fixée de manière étanche autour de l'élément intérieur, un tube latéral étant relié à l'élément extérieur entre ses deux extrémités pour communiquer avec le passage annulaire et l'élément extérieur comportant une série d'orifices radiaux à proximité de son autre extrémité.1. Surgical instrument for cleaning a cavity, characterized in that it comprises two tubular elements fitted coaxially to delimit between them an annular passage, the inner tubular element projecting from the corresponding end of the outer tubular element which is sealed around the inner member, a side tube being connected to the outer member between its two ends to communicate with the annular passage and the outer member having a series of radial holes near its other end . 2. Instrument selon la revendication 1, caractérisé en ce que le passage annulaire s'élargit dans le sens radial au niveau des orifices radiaux.2. Instrument according to claim 1, characterized in that the annular passage widens in the radial direction at the level of the radial orifices. 3. Instrument selon la revendication 2, caractérisé en ce que l'élargissement du passage annulaire est formé par un rétrécissement radial de l'élément tubulaire intérieur.3. Instrument according to claim 2, characterized in that the widening of the annular passage is formed by a radial narrowing of the inner tubular element. . . 4. Instrument selon l'une quelconque des revendications précédentes, caractérisé en ce que l'embouchure du tube latéral est conique intérieurement pour recevoir l'embout d'une seringue utilisée pour injecter du liquide dans le passage annulaire.4. Instrument according to any one of the preceding claims, characterized in that the mouth of the side tube is internally tapered to receive the tip of a syringe used to inject liquid into the annular passage. La présente invention concerne un instrument chirurgical pour le nettoyage d'une cavité, par exemple d'un site osseux préparé en vue de recevoir un élément de prothèse articulaire.The present invention relates to a surgical instrument for cleaning a cavity, for example a bone site prepared with a view to receiving an articular prosthetic element. En chirurgie osseuse, on emploie couramment des endoprothèses articulaires dont les éléments sont fixés aux os adjacents par un produit de remplissage et de fixation appelé ciment. On a pu montrer que la solidité de ce mode de fixation dépend en partie d'un parfait nettoyage du site osseux pour éliminer les fragments d'os et autres débris laissés par la préparation de l'os.In bone surgery, joint endoprostheses are commonly used, the elements of which are fixed to the adjacent bones by a filling and fixing product called cement. It has been shown that the solidity of this method of fixation depends in part on thorough cleaning of the bone site to eliminate bone fragments and other debris left by the preparation of the bone. Différents instruments ont été proposés pour nettoyer un site du corps avant un traitement ou comme phase du traitement lui-même. Ces instruments comprennent souvent deux tubes espacés coaxialement pour disposer d'un conduit permettant l'application d'un liquide nettoyant et d'un autre conduit pour éliminer le liquide superflu et d'autres choses. Pourtant, aucun de ces instruments ne semble adapté au problème spécial de nettoyer un site osseux pour préparer le mise en place d'un substitut d'articulation d'os, en particulier quand le site comprend une cavité allongée, qui pénètre longitudinalement dans l'os.Various instruments have been proposed to clean a site of the body before a treatment or as a phase of the treatment itself. These instruments often include two tubes spaced coaxially to provide a conduit for the application of cleaning liquid and another conduit for the removal of excess liquid and other things. Yet none of these instruments seem suited to the special problem of cleaning a bony site in preparation for the placement of a bone joint substitute, particularly when the site includes an elongated cavity, which extends longitudinally into the bone. La présente invention a donc pour but un instrument destiné à faciliter le nettoyage d'une cavité, par exemple d'un site osseux, particulièrement lorsqu'il s'agit d'une cavité profonde pénétrant longitudinalement dans un os long.The object of the present invention is therefore an instrument intended to facilitate the cleaning of a cavity, for example of a bone site, particularly when it is a deep cavity penetrating longitudinally into a long bone. L'instrument chirurgical selon l'invention est défini par la revendication 1.The surgical instrument according to the invention is defined by claim 1. En service, l'extrémité arrière de l'élément tubulaire intérieur est reliée à une source de dépression et le tube latéral de l'élément extérieur est relié à une source de liquide de nettoyage sous pression. La partie avant de l'instrument étant engagée dans la cavité à nettoyer, le liquide sous pression qui circule dans le passage annulaire s'échappe à l'extrémité de l'instrument sous la forme d'un jet annulaire et également par les orifices latéraux sous la forme d'une série de jets radiaux. Ces jets de liquide délogent les fragments d'os et les débris pour les entraîner dans le passage central où le liquide de nettoyage est aspiré.In use, the rear end of the inner tubular element is connected to a source of vacuum and the side tube of the outer element is connected to a source of cleaning liquid under pressure. The front part of the instrument being engaged in the cavity to be cleaned, the pressurized liquid which circulates in the annular passage escapes at the end of the instrument in the form of an annular jet and also through the side orifices as a series of radial jets. These jets of liquid dislodge bone fragments and debris into the central passage where the cleaning liquid is drawn in. La figure unique est une coupe longitudinale d'une forme de l'instrument de l'invention représentée à titre d'illustration.The single figure is a longitudinal section of a form of the instrument of the invention shown by way of illustration. L'instrument chirurgical se compose de deux tubes de métal 10, 11 de sections circulaires différentes dont l'un, 10, est plus long que l'autre. Les deux tubes sont emboîtés coaxialement et l'extrémité arrière du tube intérieur 10 dépasse au-delà de celle du tube extérieur 11. Les extrémités avant des deux tubes sont sensiblement au même niveau. Le diamètre extérieur du tube intérieur est légèrement plus petit que le diamètre intérieur du tube extérieur sur la majeure partie de sa longueur pour délimiter entre eux un passage annulaire 12. Sur le reste de sa longueur, le tube intérieur 10 s'élargit à un diamètre égal au diamètre intérieur du tube extérieur 11. L'extrémité arrière du tube extérieur 11 est filetée en 13 pour recevoir une bague 14 munie d'un joint 15 qui assure l'étanchéité de l'ensemble lorsque la bague est vissée sur la partie filetée du tube extérieur.The surgical instrument consists of two metal tubes 10, 11 of different circular sections, one of which, 10, is longer than the other. The two tubes are nested coaxially and the rear end of the inner tube 10 protrudes beyond that of the outer tube 11. The front ends of the two tubes are substantially at the same level. The outer diameter of the inner tube is slightly smaller than the inner diameter of the outer tube over most of its length to define between them an annular passage 12. Over the remainder of its length, the inner tube 10 widens to a diameter equal to the inside diameter of the outer tube 11. The rear end of the outer tube 11 is threaded at 13 to receive a ring 14 provided with a seal 15 which seals the assembly when the ring is screwed onto the threaded part of the outer tube. Un tube latéral 16 est soudé sur le côté du tube extérieur 11 de manière à communiquer avec le passage annulaire 12. On voit sur la figure que le tube 16 s'étend obliquement sur le côté de l'instrument.A side tube 16 is welded to the side of the outer tube 11 so as to communicate with the annular passage 12. It can be seen in the figure that the tube 16 extends obliquely on the side of the instrument. A proximité de son extrémité avant, le tube extérieur 11 est percé d'une série de trous radiaux 17 et le tube intérieur 10 comporte un étranglement 18 qui délimite un élargissement du passage annulaire 12 au niveau des orifices 17.Near its front end, the outer tube 11 is pierced with a series of radial holes 17 and the inner tube 10 includes a constriction 18 which delimits a widening of the annular passage 12 at the level of the orifices 17. Le liquide de nettoyage est injecté dans l'instrument par le tube latéral 16 qui communique avec le passage annulaire 12. L'extrémité arrière du tube intérieur 10 est reliée à une source de dépression convenable. L'élargissement du passage 12, qui correspond à la partie rétrécie 18 du tube intérieur, forme un réservoir local de liquide sous pression pour assurer une distribution régulière à tous les orifices radiaux 17. Pour l'alimentation en liquide de nettoyage, il est commode d'utiliser une grosse seringue jetable dont l'embout est engagé dans l'embouchure conique 19 du tube latéral 16. La dépression peut être appliquée au tube intérieur 10 par un flexible enfilé sur le bout du tube qui comporte un élargissement 20 assurant un forcement convenable du flexible.The cleaning liquid is injected into the instrument through the side tube 16 which communicates with the annular passage 12. The rear end of the inner tube 10 is connected to a suitable source of vacuum. The widening of the passage 12, which corresponds to the narrowed part 18 of the inner tube, forms a local reservoir of liquid under pressure to ensure an even distribution to all the radial orifices 17. For the supply of cleaning liquid, it is convenient to use a large disposable syringe, the tip of which is engaged in the conical mouth 19 of the side tube 16. suitable for the hose. 22 55 1010 1515 2020 2525 3030 3535 4040 4545 RR 1 feuille dessins1 drawing sheet
