Abstract
APPLICATEUR A MAIN POUR LA CHIRURGIE A LASER DANS LEQUEL UNE FIBRE OPTIQUE REFROIDIE COAXIALEMENT PAR LIQUIDE OU PAR GAZ EST MONTE DANS UN CARTER-POIGNEE EN FORME DE TUBE. L'EMBOUT TUBULAIRE ALLONGE 17, 18 EST FABRIQUE EN UN ALLIAGE METALLIQUE MOU QUI PEUT ETRE DEFORME A LA MAIN SELON LES EXIGENCES DES PRESCRIPTIONS MEDICALES.HAND APPLICATOR FOR LASER SURGERY IN WHICH AN OPTICAL FIBER COAXIALLY COAXED BY LIQUID OR GAS IS MOUNTED IN A TUBE-SHAPED HANDLE CASE. THE ELONGATED TUBULAR TIP 17, 18 IS MADE OF A SOFT METAL ALLOY WHICH CAN BE HAND-SHAPED ACCORDING TO THE REQUIREMENTS OF MEDICAL SPECIFICATIONS.
Description
Applicateur à main pour la chirurgie à laser L'invention se rapporte à unHand applicator for laser surgery The invention relates to a
applicateur à main pourhand applicator for
la chirurgie à laser dans lequel une fibre optique refroidie 5 coaxialement par liquide ou par gaz est montée dans un carterpoignée en forme de tube. laser surgery in which a coaxially cooled liquid or gas cooled optical fiber is mounted in a tubular shaped housing.
De tels applicateurs sont connus dans différents modes de réalisation Les appareils utilisés jusqu'ici comportent une optique de focalisation pour permettre de choisir libre10 ment la distance d'irradiation et sont donc de très grandes dimensions Leur diamètre minimal moyen est de 12 mm et leur longueur minimale se situe aux alentours de 12 cm Les petits tubes de guidage de la fibre optique ont desdiamètres de 3 à 4 mm et sont réalisés dans des formes diverses selon l'endroit 15 de l'application Il en résulte la nécessité de changer plusieurs fois le petit tube de guidage pour chaque intervention Indépendamment de l'interruption indésirable de l'application, ces changements impliquent une prolongation de la durée de l'opération et une réserve spéciale de petits 20 tubes de différentes courbures qui doivent être préparés à Such applicators are known in various embodiments. The apparatuses hitherto used have a focusing optics to allow free choice of the irradiation distance and are therefore very large. Their mean minimum diameter is 12 mm and their length The small guide tubes of the optical fiber have diameters of 3 to 4 mm and are made in various shapes depending on the location of the application. This results in the need to change the small guide tube for each intervention Regardless of the undesirable interruption of the application, these changes imply an extension of the duration of the operation and a special reserve of small tubes of different curvatures which must be prepared for
l'avance et encombrent inutilement la table porte-instruments. in advance and unnecessarily clutter the instrument table.
La présente invention a par conséquent pour objet de mettre au point un applicateur à main du type précité qui supprime tout changement long et délicat pendant l'opération 25 ainsi que la nécessité de préparer à l'avance plusieurs petits It is therefore an object of the present invention to provide a hand applicator of the aforesaid type which eliminates any long and delicate changes during the operation as well as the need to prepare several small children in advance.
tubes de formes différentes.tubes of different shapes.
Ce résultat est atteint selon l'invention par le fait que l'embout tubulaire allongé est fabriqué en un alliage This result is achieved according to the invention in that the elongate tubular tip is made of an alloy
métallique mou qui peut être déformé manuellement selon les 30 exigences des prescriptions médicales. soft metal which can be manually deformed according to the requirements of medical prescriptions.
L'invention sera mieux comprise à l'aide de la The invention will be better understood using the
description d'un mode de réalisation pris comme exemple, mais description of an embodiment taken as an example but
non limitatif, et illustré par le dessin annexé. non-limiting, and illustrated by the accompanying drawing.
L'exemple de réalisation représenté sur la figure du dessin est constitué par deux dits sous-ensembles, à savoir par The exemplary embodiment shown in the figure of the drawing consists of two so-called subassemblies, namely by

à l'état de la technique, une description parait superflue. in the state of the art, a description seems superfluous.
Le petit tube flexible 18 peut être fabriqué en un alliage de laiton mou, mais on peut aussi envisager d'autres alliages L'essentiel est que le petit tube puisse être facilement courbé à la main sans qu'il se produise d'amorce de rupture et qu'il puisse être à chaque instant ramené à sa position première D'autres alliages métalliques en plomb ou en zinc peuvent bien entendu être aussi envisagés, la condition The small flexible tube 18 can be made of a soft brass alloy, but other alloys can also be envisaged. The essential point is that the small tube can be easily bent by hand without breaking primer. and that it can be brought back to its original position at any moment. Other metal alloys made of lead or zinc can of course also be envisaged.
