Abstract
Description
La présente invention concerne les outils utilisés dans l'art dentaire pour l'alésage des canaux, et notamment ceux qui comportent une portion active en forme de tige conique effilée portant sur toute sa longueur des barbelures, conformément au brevet français Riitano N0 77/36980. The present invention relates to tools used in dentistry for boring canals, and in particular those which include an active portion in the form of a tapered conical rod carrying over its entire length barbs, in accordance with French patent Riitano N0 77/36980 .
Un tel outil est habituellement employé à la main, mais, dans le but d'effectuer l'évasement du canal, on a tenté de le monter sur un instrument vibratoire lui conférant une oscillation multidirectionnelle rapide, bien que demeurant subsonique, ce qui a pour effet de diminuer le temps d'alésage. Such a tool is usually used by hand, but, in order to flare the canal, an attempt has been made to mount it on a vibrating instrument giving it a rapid multidirectional oscillation, although remaining subsonic, which has the purpose of effect of reducing the boring time.
Toutefois on a constaté que, dans ce cas, il pouvait arriver que les barbelures de l'outil se cassent et demeurent plantées dans les parois du canal, ce qui n' est évidemment pas recommande. However, it has been found that, in this case, it could happen that the barbs of the tool break and remain planted in the walls of the channel, which is obviously not recommended.
La présente invention vise à éliminer cet inconvénient grâce à un outil qui se caractérise également par une tige conique allongée, mais qui, au lieu de porter des barbelures, présente une rainure hélicoidale à pas progressif à la fois en largeur et en profondeur, étant plus petit vers la pointe et plus grand vers le manche. The present invention aims to eliminate this drawback by means of a tool which is also characterized by an elongated conical rod, but which, instead of carrying barbs, has a helical groove with progressive pitch both in width and in depth, being more small towards the tip and larger towards the handle.
L'expérience a montré que l'utilisation d'un tel ou til sur un instrument vibratoire du genre précité permettait d'obtenir un alésage aussi rapide ét satisfaisant qu'avec l'outil à barbelures précité, mais sans l'lnconvénient de ces barbelures. Experience has shown that the use of such or such on a vibratory instrument of the aforementioned kind makes it possible to obtain a bore as rapid and satisfactory as with the aforementioned barbed tool, but without the drawback of these barbs. .
L'invention sera mieux comprise en se reportant à la description.qui suit d'un mode de réalisation du nouvel outil, correspondant au dessin annexé, qui représente latéralement cet outil, à échelle agrandie. The invention will be better understood by referring to the description. Which follows of an embodiment of the new tool, corresponding to the appended drawing, which represents this tool laterally, on an enlarged scale.
On voit ainsi que cet outil se compose d'une tige 1 et d'un manche 2. La tige 1, d'une vingtaine de mm de longueur, est conique, et effilée depuis le manche 2 vers la pointe 4. It can thus be seen that this tool consists of a rod 1 and a handle 2. The rod 1, about twenty mm in length, is conical, and tapered from the handle 2 towards the point 4.
Ce cône porte lui-même une rainure hélicoïdale 3, doublement progressive en ce que son pas et sa profondeur diminuent également depuis le manche 2 jusqu'à. la pointe 4.This cone itself carries a helical groove 3, doubly progressive in that its pitch and its depth also decrease from the handle 2 to. tip 4.
Cet outil peut être monté par son manche 2 dans un instrument-tel que décrit dans le brevet français 82 18545, qui à partir d'une vibration rapide subsonique lui confèrera des oscillations multidirectionnelles d'une amplitude progressive vers la pointe 4. Le déplacement oscillatoire de l'outil à l'intérieur du canal lui permet ainsi de rester en contact avec la surface totale des parois de ce dernier et d'effectuer ainsi un alésage avec évasement de I'embranchure du canal et le redressement des courbures, sans risque de rencontrer les inconvénients précités des outils antérieurs. This tool can be mounted by its handle 2 in an instrument-as described in French patent 82 18545, which from a rapid subsonic vibration will give it multidirectional oscillations of progressive amplitude towards the tip 4. The oscillatory displacement of the tool inside the channel thus allows it to remain in contact with the total surface of the walls of the latter and thus to carry out a bore with flare of the junction of the channel and the straightening of the curvatures, without risk of meet the aforementioned drawbacks of prior tools.
Bien entendu la conicité de la tige 1 peut être variable suivant sa grosseur, ainsi que les valeurs relatives du pas et de la profondeur de la rainure 3. Of course, the taper of the rod 1 can be variable depending on its size, as well as the relative values of the pitch and the depth of the groove 3.
