Abstract

It consists of a moving guide (3) surrounding the drill and fixed to the head of the handpiece via an elastic means which can be compressed, the front part (7) of the said guide pressing throughout the drilling against the gum which it compresses, and the guide comprising a through-bore for the drill (2) to pass through. Application: drilling of the cortical bone of the jaw.

Description

L'invention a pour objet un accessoire de guidage pour un foret monté sur une pièce 9 main dedentisterie et utilisé essentiellement pour la perforation de la corticale osseuse de la machoire. The subject of the invention is a guide accessory for a drill mounted on a piece of dental hand and used essentially for the perforation of the bone cortex of the jaw.

Lors de ses interventions, le chirurgien dentiste est couramment confronté au problème de devoir perforer la corticale osseuse de la machoire pour atteindre la partie centrale de l'os. Ceci est le cas tout particulièrement pour effectuer des anesthésies. Avant d'atteindre la corticale proprement dite avec le foret, il faut au préalable traverser la gencive. I1 se pose a ce niveau de très gros problèmes. During his interventions, the dental surgeon is commonly faced with the problem of having to perforate the bony cortex of the jaw to reach the central part of the bone. This is particularly the case for performing anesthesia. Before reaching the cortex proper with the drill, you must first cross the gum. There are very big problems at this level.

En effet, la gencive a une structure fibreuse. Dès le premier contact du foret avec celle-ci, une fibre staccroche à une lèvre du foret et elle s'enroule autour de la tige en rotation du foret. On risque ainsi de déchirer tout un lambeau de chair sur plusieurs centimètres et conduire à une véritable mutilation du patient. Indeed, the gum has a fibrous structure. From the first contact of the drill with it, a fiber staccroche a lip of the drill and it wraps around the rotating rod of the drill. There is thus a risk of tearing a whole flap of flesh over several centimeters and leading to real mutilation of the patient.

D'autre part, si le foret est long, lorsque son extrémité vient au contact de l'os tout en tournant, elle est projetée latéralement et le foret se tord sans que le chirurgiendentiste ne puisse avoir le temps de s'en rendre compte et de réagir. I1 y a alors double risque de rupture et de déchirure des tissus mous. On the other hand, if the drill is long, when its end comes into contact with the bone while rotating, it is thrown laterally and the drill twists without the surgeon having time to notice it and to react. There is then a double risk of rupture and tearing of the soft tissues.

La présente invention a pour objet de pallier ces divers inconvenients des dispositifs connues,
Conformément a l'invention ce résultat est obtenu avec un accessoire de guidage pour un foret monté sur une pièce main de dentisterie et utilisé essentiellement pour la perforation de la corticale osseuse de la machoire,- caractérisé en ce qu'il consiste en un guide mobile entourant le forêt et fixé a la tête de la pièce à main par l'intermédiaire d'un moyen élastique pouvant être comprimé, la partie frontale dudit guide venant s'appliquer pendant toute la durée de la perforation contre la gencive qu'il comprime et le guide comportant un alésage traversant pour le passage du foret.
The object of the present invention is to overcome these various drawbacks of known devices,
According to the invention this result is obtained with a guide accessory for a drill mounted on a hand piece of dentistry and used essentially for the perforation of the bone cortex of the jaw, - characterized in that it consists of a movable guide surrounding the forest and fixed to the head of the handpiece by means of an elastic means which can be compressed, the front part of said guide coming to apply throughout the duration of the perforation against the gum which it compresses and the guide comprising a through bore for the passage of the drill.

On comprendra aisément que en position non comprimée, l'ensemble du guide et de son moyen support élastique est plus long que la longueur utile du foret, le foret ne faisant donc pas saillie en position de repos par rapport au plan de la face frontale du guide. C'est seulement lorsque l'on exerce une pressio sur le moyen élastique en appliquant le guide sur la gencive et en appuyant sur la pièce a main que le foret vient a dépasser le guide et a pénétrer la gencive comprimée. Du fait de la compression il n'y a plus arrachage des fibres de la gencive, En effet les fibres qui pourraient adhérer aux lèvres du foret sont coincées entre l'os et le guide et cassent sans pouvoir s'enrouler autour du foret. It will easily be understood that in the uncompressed position, the assembly of the guide and of its elastic support means is longer than the useful length of the drill, the drill therefore not protruding in the rest position relative to the plane of the front face of the guide. It is only when a pressure is exerted on the elastic means by applying the guide on the gum and pressing on the handpiece that the drill comes to exceed the guide and to penetrate the compressed gum. Due to the compression there is no longer pulling out of the gum fibers. In fact the fibers which could adhere to the lips of the drill are wedged between the bone and the guide and break without being able to wrap around the drill.

Ce guide peut être monté de manière amovible ou définitive sur la tête de la pièce à main. This guide can be removably or permanently mounted on the head of the handpiece.

On comprendra mieux l'invention grâce a la description ci-après d'un mode préféré de réalisation, en référence aux dessins annexés dans lesquels
- la figure 1 est une vue d'une tête de contreangle équipée classiquement d'un foret,
- la figure 2 est une vue d'un guide amovible adaptable sur la tête de contre-angle de la figure 1,
- la figure 3 est une vue du guide amovible de la figure 2 positionné sur la tête de contre-angle de la figure 1,
- la figure 4 est une vue du dispositif selon l'invention enune position intermédiaire en cours de fonctionnement.
The invention will be better understood from the following description of a preferred embodiment, with reference to the accompanying drawings in which
FIG. 1 is a view of a counter-angle head conventionally equipped with a drill,
FIG. 2 is a view of a removable guide adaptable to the contra-angle head of FIG. 1,
FIG. 3 is a view of the removable guide of FIG. 2 positioned on the contra-angle head of FIG. 1,
- Figure 4 is a view of the device according to the invention in an intermediate position during operation.

On a représenté la figure I une tête de contreangle (1) de type en soi indifférent, qui peut d'ailleurs éventuellement être une pièce à main droite. Sur la tête du contreangle est monté un foret (2) animé de manière connu d'un mouvement de rotation. Cette représentation illustre en fait clairement l'art antérieur. FIG. I shows a counter-ruler head (1) of an indifferent type per se, which can moreover possibly be a right handpiece. On the head of the contra-angle is mounted a drill (2) animated in a known manner with a rotational movement. This representation in fact clearly illustrates the prior art.

On a représenté à la figure 2 un accessoire conforme à l'invention constitué essentiellement d'un guide canon (3) fixé à l'une des extrémités d'un ressort à boudin (4), luimême fixé à son autre extrémité à une griffe de fixation (5). Le guide (3) est de forme générale en tronc de cone et comporte un alésage central traversant (6). FIG. 2 shows an accessory according to the invention essentially consisting of a barrel guide (3) fixed to one end of a coil spring (4), itself fixed at its other end to a claw fixing (5). The guide (3) is generally in the form of a truncated cone and has a through central bore (6).

En position prête à l'utilisation, représentée à la figure 3, l'accessoire est fixé sur la tête du contre-angle par l'intermédiaire de la griffe (5), ou bien entendu par tout moyen d'accrochage équivalent. Comme indiqué précédemment, lten- semble peut également être fixé définitivement sur la tête de contre-angle. On constate à la figure 3 que le foret (2) ne fait pas saillie par rapport au plan frontal (7) du guide (3). In the ready-to-use position, shown in FIG. 3, the accessory is fixed to the head of the contra-angle via the claw (5), or of course by any equivalent attachment means. As previously indicated, the lens can also be permanently fixed to the contra-angle head. It can be seen in FIG. 3 that the drill (2) does not protrude relative to the frontal plane (7) of the guide (3).

Lorsque l'on désire perforer la gencive d'un patient, on applique la face (7) du guide (3) sur la gencive et on exerce une pression sur la tête de contre-angle tendant à faire se contracter le ressort (4) , Dès que la pointe du foret affleure le plan (7) la perforation commence, Si on continue la pression sur la tête du contre-angle la perforation commence et le foret pénétre comme désiré dans la gencive, le ressort (4) se comprimant de plus en plus. On a schématisé à la figure 4 une position intermédiaire avec la gencive (8) et l'extrémité distale du foret (2) qui y a pénétré. When it is desired to perforate the gum of a patient, the face (7) of the guide (3) is applied to the gum and pressure is applied to the contra-angle head tending to cause the spring (4) to contract. , As soon as the point of the drill is flush with the plane (7) the perforation begins, If one continues the pressure on the head of the contra-angle the perforation begins and the drill penetrates as desired in the gum, the spring (4) compressing more and more. There is shown diagrammatically in FIG. 4 an intermediate position with the gum (8) and the distal end of the drill (2) which has entered it.

Le diamètre de l'alésage (6) du guide canon (3) est légèrement supérieur au diamètre maximal du foret. The diameter of the bore (6) of the barrel guide (3) is slightly greater than the maximum diameter of the drill.

Le foret pourra être de tout type, soit très fin pour le passage d'une aiguille pour anesthésie, soit plus gros en vue d'une résection apicale. The drill can be of any type, either very fine for the passage of a needle for anesthesia, or larger for an apical resection.

On comprendra donc que la fonction du guide (3) est double
- comprimer des tissus de la gencive de manière à éviter un arrachement ;
- guidage du foret à une certaine distance de la tête de la pièce à main, écartant ainsi les risques de torsion de celui-ci.
It will therefore be understood that the function of the guide (3) is twofold
- compress gum tissue so as to avoid tearing;
- guiding the drill at a certain distance from the head of the handpiece, thus eliminating the risk of it twisting.
