Abstract

Endodontia instruments or armoured cords coated with a layer or an absorbing lapping. They are intended to dry or absorb a liquid, apply or impregnate any substance, or remove debris inside a pulp canal or a cavity.

Description

COTOMECHE OU CORDON ODONTOLOGIQUE La présente invention concerne principalement les instruments du type : instruments d'endodontie utilisés en odontostomatologie pour les traitements dentaires. Cet instrument permet de sécher, d'absorber ou de permettre l'application ou l'imprégnation d'une substance quelconque au niveau des différents éléments de la cavité buccale ; il pourra éventuellement rester temporairement dans une dent ou servir de support aux produits de parage endocanalaires. The present invention relates mainly to instruments of the type: endodontic instruments used in odontostomatology for dental treatments. This instrument makes it possible to dry, absorb or allow the application or impregnation of any substance at the level of the various elements of the oral cavity; it may possibly remain temporarily in a tooth or serve as a support for endocanal trimming products.
Dans les dispositifs connus de ce genre : 1°) - Les pointes de papier absorbantes sont difficiles à utiliser dès qu'elles sont humides. La pointe se tord et on ne peut les enfiler dans les racines fines.In known devices of this kind: 1) - The absorbent paper tips are difficult to use as soon as they are wet. The point twists and you cannot thread them into the fine roots.
D'autre part, le cône de papier une fois mouillé peut se déchirer lors du retrait et un fragment peut rester dans le canal.On the other hand, the paper cone once wet can tear during removal and a fragment can remain in the canal.
2°) - Les mèches confectionnées extemporanément à partir de fibres de coton enroulées sur un instrument métallique (sonde, tire-nerf ou autres) ont pour inconvénient le risque de laisser des fibres dans les canaux qui pourraient entrainer des putréfactions. Elles sont fastidieuses à fabriquer, à stéréliser et il est difficile de les calibrer de façon précise ; de plus, les fibres n'étant pas fixées glissent le long de l'instrument lors d'une friction dans un canal et ne peuvent alors jouer leur rôle à l'extrémité de l'instrument au fond du canal. Les COTOMECHES selon l'invention permettent d'éviter ces inconvénients et rendent possibles d'autres applications.2 °) - Wicks made extemporaneously from cotton fibers wound on a metal instrument (probe, nerve puller or other) have the disadvantage of the risk of leaving fibers in the channels which could lead to putrefaction. They are tedious to manufacture, to sterilize and it is difficult to calibrate them with precision; moreover, the fibers which are not fixed slide along the instrument during friction in a channel and cannot then play their role at the end of the instrument at the bottom of the channel. The COTOMECHES according to the invention make it possible to avoid these drawbacks and make other applications possible.
La "cotomèche" selon l'invention se compose d'une tige pouvant être métallique ou en matériau synthétique sur laquelle est fixée une matière absorbante qui suivant sa nature pourra être enroulée, tressée, projetée, polymérisée ou appliquée autour.The "cotomèche" according to the invention consists of a rod which may be metallic or made of synthetic material on which is fixed an absorbent material which according to its nature can be wound, braided, sprayed, polymerized or applied around.
Selon une première variante (Fig.l) la cotomèche sera constituée par une tige métallique (l) sur laquelle sera fixée par collage direct ou indirect ou thermocollage une épaisseur de matière absorbante qui pourra être constituée par des fibres, des fils (2) ou des bandes. Ces fils pourront être apprêtés et traités spécialement avant dêtre enroulés et fixés autour de l'âme centrale. Ce guipage peut être obtenu par simple enroulement, par enroulements croisés ou superposés, tressage ou autres procédés. On peut obtenir un effet analoque par fixation d'une feuille de papier ou de matière absorbante. Le renfort métallique peut être tressé avec le fil absorbant et suivant sa section, peut également jouer un rôle de racleur. Selon la 2ème variante (Fig.2), la tige centrale est usinée ou laminée (l) de façon à créer des logettes qui seront garnies de matière absorbante (2). L'avantage de ce procédé est d'éviter tout effilochage de la matière absorbante lorsque celle ci n'est pas constituée par du fil enroulé. Selon la 3ème variante, la mèche qui peut être réalisée selon la première ou la seconde variante est imprégnée lors de sa fabrication d'une substance particulière. Ce peut être par exemple un hémostatique ou un vasoconstricteur destiné à arrêter une hémorragie intracanalaire, ou une substance permettant une rétraction de gencive avec une diminution des gingivorragies, la mèche étant placée autour du collet de la dent ou dans les zones proximales interdentaires.According to a first variant (Fig.l) the cotomèche will consist of a metal rod (l) on which will be fixed by direct or indirect bonding or heat bonding a thickness of absorbent material which may be constituted by fibers, threads (2) or tapes. These wires can be specially prepared and treated before being wound and fixed around the central core. This covering can be obtained by simple winding, by crossed or superimposed windings, braiding or other processes. A similar effect can be obtained by attaching a sheet of paper or absorbent material. The metal reinforcement can be braided with the absorbent wire and, depending on its section, can also act as a scraper. According to the 2nd variant (Fig. 2), the central rod is machined or laminated (l) so as to create cubicles which will be filled with absorbent material (2). The advantage of this process is to avoid any fraying of the absorbent material when the latter is not constituted by coiled wire. According to the 3rd variant, the wick which can be produced according to the first or the second variant is impregnated during its manufacture with a particular substance. It can be for example a hemostatic or a vasoconstrictor intended to stop an intracanal hemorrhage, or a substance allowing a retraction of gum with a reduction in gingivorrhagia, the wick being placed around the neck of the tooth or in the interdental proximal areas.
Les dispositifs de la présente invention peuvent être utilisés chaque fois que l'on voudra réaliser des instruments capables d'absorber des éléments liquides ou pâteux, dans le but de sécher ou d'assainir un canal, un sulcus ou une zone papillaire. Ils pourront suivant les indications se présenter avec ou sans manche, (Fig.1) (3) avec une section ronde (pour un usage intracanalaire par exemple) ou une section plate ou en dièdre (Fig.3) pour un usage coronnaire ou proximal: (1) matrice préformée, (2) revêtement.The devices of the present invention can be used whenever it is desired to make instruments capable of absorbing liquid or pasty elements, with the aim of drying or sanitizing a canal, a sulcus or a papillary zone. Depending on the indications, they can be presented with or without a handle, (Fig. 1) (3) with a round section (for intraductal use for example) or a flat or dihedral section (Fig. 3) for coronal or proximal use : (1) preformed matrix, (2) coating.
Le procédé sera utilisé lorsqu'on voudra appliquer certains médicaments ou produits à l'intérieur des racines des dents ou lorsqu'on voudra retirer certains débris ou poussières.The process will be used when you want to apply certain drugs or products inside the roots of your teeth or when you want to remove certain debris or dust.
Par extention d'autres applications peuvent se trouver en mécanique (même autres que l'art dentaire), graissage de certains organes délicats, ou pour retirer certains produits (type cambouis), ou assécher certains micro circuits. Domaines d'applicationBy extension other applications can be found in mechanics (even other than dentistry), lubrication of certain delicate organs, or to remove certain products (sludge type), or to dry out certain micro circuits.
