Abstract
(EN)
The present invention relates to a device to be inserted into the Eustachian tube, and to a device to be inserted into the Eustachian tube, capable of treating Patulous Eustachian tube, which is a disorder in which the Eustachian tube stays open intermittently or continuously. In order to accomplish the aforementioned objective, the device to be inserted into the Eustachian tube, according to the present invention, comprises: a tail part which is inserted into the expanded Eustachian tube and which has a cross section formed in an oval shape; a head part which is divided into two tubes at the tail part and which has the two tubes provided at an angle of 10-20°, so as not to slip in the Eustachian tube after the tail part is inserted; and catching parts extended from the two tubes of the head part and horizontally bent so as to be caught, wherein the catching parts, the head part, and the tail part are manufactured with silicon, and the tail part is inserted through tympanotomy. In addition, in the tail part, the length ratio of the cross section of one end portion, connected to the head part, to the cross section of the other end portion is 2.0:1.0. Furthermore, one or more from among the catching parts, the head part, and the tail part have marker parts containing inorganic substances or metals. Additionally, one or more from among the catching parts, the head part, and the tail part have surfaces coated with antibiotics. Moreover, one or more from among the catching parts, the head part, and the tail part have surfaces coated with steroids. [Representative drawing] Figure 2

La présente invention concerne un dispositif destiné à être inséré dans la trompe d'Eustache, et un dispositif à insérer dans la trompe d'Eustache, apte à traiter une distension de la trompe d'Eustache, qui est un trouble dans lequel la trompe d'Eustache reste ouverte de façon intermittente ou continue. Afin d'atteindre l'objectif susmentionné, le dispositif à insérer dans la trompe d'Eustache, selon la présente invention, comprend : une partie queue qui est insérée dans la trompe d'Eustache dilatée et qui présente une section transversale formée sous une forme ovale ; une partie tête qui est divisée en deux tubes au niveau de la partie queue et qui a les deux tubes disposés selon un angle de 10 à 20°, de façon à ne pas glisser dans la trompe d'Eustache après l'insertion de la partie queue ; et des parties d'accrochage étendues à partir des deux tubes de la partie tête et pliées horizontalement de façon à être accrochées, les parties d'accrochage, la partie tête et la partie queue étant fabriquées avec du silicium, et la partie queue étant insérée par paracentèse du tympan. De plus, dans la partie queue, le rapport de longueur de la section transversale d'une partie d'extrémité, reliée à la partie tête, à la section transversale de l'autre partie d'extrémité est de 2,0:1,0. En outre, une ou plusieurs parties parmi les parties d'accrochage, la partie tête et la partie queue ont des parties de marqueur contenant des substances inorganiques ou des métaux. De plus, une ou plusieurs parties parmi les parties d'accrochage, la partie tête et la partie queue ont des surfaces revêtues d'antibiotiques. De plus, une ou plusieurs parties parmi les parties d'accrochage, la partie tête et la partie queue ont des surfaces revêtues de stéroïdes. Drawing_references_to_be_translated
