Description

La présente invention a pour objet une seringue dentaire pour injections intra-ligamentaires, du type comportant une aiguille d'injection, une carpule contenant le--liquide à injecter et un piston commandant le déplacement du fond de la carpule. The present invention relates to a dental syringe for intra-ligamentary injections, of the type comprising an injection needle, a cartridge containing the liquid to be injected and a piston controlling the movement of the bottom of the cartridge.

Des seringues de ce type sont connues. Elles ont été déjà décrites par exemple dans le brevet FR I 583 163 au nom de la demanderesse. Syringes of this type are known. They have already been described for example in patent FR I 583 163 in the name of the applicant.

Toutefois, les seringues ne peuvent convenir pour l'injection de produits dans les ligaments situés entre lotos de la machoire et la dent. However, syringes are not suitable for injecting products into the ligaments located between the lotos of the jaw and the tooth.

L'intervalle entre l'os et la dent est étroit ; or on doit y introduire une aiguille très fine et souple. Pour que le liquide arrive à passer dans cette aiguille et puisse être expulsé, il faut lui imprimer une pression d'injection très élevée. The interval between the bone and the tooth is narrow; however, a very fine and flexible needle must be introduced into it. In order for the liquid to pass through this needle and be able to be expelled, it must be given a very high injection pressure.

Une simple pression sur le piston imprimée par la paume de la main, comme cela est le cas pour les seringues ordinaires, ne peut convenir. A simple pressure on the plunger printed by the palm of the hand, as is the case with ordinary syringes, is not suitable.

L'invention a pour objet en conséquence une seringue pour injections intra-ligamentaires permettant de remédier a ces inconvénients. The subject of the invention is therefore a syringe for intra-ligamentary injections which makes it possible to remedy these drawbacks.

Conformément à l'invention, ce résultat est obtenu avec une seringue dentaire pour injections intra-ligamentaires, du type comportant une aiguille d'injection, une carpule contenant le liquide à injecter et un piston commandant le déplacement du fond de la carpule, caractérisé en ce que le déplacement du piston vers la carpule est commandé par un levier comme portant un cliquet coopérant avec une crémaillère ménagée sur le piston, assurant une démultiplication de la pression manuelle exercée par l'utilisateur sur ledit levier. According to the invention, this result is obtained with a dental syringe for intra-ligamentary injections, of the type comprising an injection needle, a cartridge containing the liquid to be injected and a piston controlling the movement of the bottom of the cartridge, characterized in that the displacement of the piston towards the cartridge is controlled by a lever as carrying a pawl cooperating with a rack formed on the piston, ensuring a reduction in the manual pressure exerted by the user on said lever.

La force de la pression manuelle exercée par 1 'utili- sateur étant multipliée, l'expulsion du liquide hors de la carpule peut intervenir sans problèmes. The force of the manual pressure exerted by the user being multiplied, the expulsion of the liquid out of the cartridge can occur without problems.

En outre l'effort exercé par l'utilisateur étant malgré tout moindre qu'avec les seringues de l'art antérieur, il s'ensuit de meilleures conditions de travail et une meilleure précision dans l'intervention. In addition, the effort exerted by the user being despite everything less than with the syringes of the prior art, this results in better working conditions and better precision in the intervention.

On comprendra mieux l'invention à l'aide de la description ci-apres, faite en référence aux dessins annexés dans lesquels
- la figure I est une vue en coupe longitudinale partielle d'une seringue conforme à l'invention
- la figure 2 est une variante de mise en oeuvre avec un support d'aiguille incliné
- la figure 3 est une variante d'exécution du dispositif démultiplicateur de la seringue de la figure 1, en coupe longitudinale et en vue partielle.
The invention will be better understood using the description below, made with reference to the accompanying drawings in which
- Figure I is a partial longitudinal sectional view of a syringe according to the invention
- Figure 2 is an alternative embodiment with an inclined needle holder
- Figure 3 is an alternative embodiment of the multiplier device of the syringe of Figure 1, in longitudinal section and in partial view.

La seringue (1) représentée à la figure 1 comporte essentiellement
- un corps (2) sur lequel est articulé le levier (3) de commande de la seringue,
- un support de carpule (4) dans lequel est enfilée la carpule (5),
- un embout (6) comportant une aiguille d'injection (7).
The syringe (1) represented in FIG. 1 essentially comprises
- a body (2) on which the lever (3) for controlling the syringe is articulated,
- a cartridge holder (4) into which the cartridge (5) is threaded,
- a nozzle (6) comprising an injection needle (7).

La carpule (5) se présente, de manière connue, sous la forme d'un réservoir oblong renfermant le liquide à injecter. The cartridge (5) is, in known manner, in the form of an oblong reservoir containing the liquid to be injected.

Elle comporte à l'une de ses extrémités une pastille de caoutchouc (8) qui sera traversée par la partie arrière (9) de l'ai- guille (7). De ce fait, le contenu de la carpule peut n'être utilisé que partiellement. Le fond de la carpule consiste en un disque mobile en translation et repoussant, dans son déplacement, le liquide à injecter vers l'aiguille.It has at one of its ends a rubber patch (8) which will be crossed by the rear part (9) of the needle (7). As a result, the contents of the cartridge may be used only partially. The bottom of the carpule consists of a disc movable in translation and pushing, in its movement, the liquid to be injected towards the needle.

Le support de carpule (4) comporte une lumière (10) permettant de surveiller le niveau de remplissage de la carpule. The cartridge holder (4) has a light (10) for monitoring the filling level of the cartridge.

Le support de carpule (4) est relié au corps (2) de manière amovible, pour permettre le placement et le retrait des carpules, par exemple par un système à baïonnette (11) de structure classique et qui ne sera donc pas décrit plus en détails. The cartridge holder (4) is connected to the body (2) in a removable manner, to allow the placement and removal of the cartridges, for example by a bayonet system (11) of conventional structure and which will therefore not be described further details.

Dans le corps (2) coulisse un piston (12) cylindrique, comportant une rainure de guidage longitudinale (13) dans laquelle est assujettie une clavette (14) fixe solidaire du corps (2). De cette manière, le piston ne peut tourner autour de son axe longitudinal. In the body (2) slides a cylindrical piston (12), comprising a longitudinal guide groove (13) in which is fixed a fixed key (14) integral with the body (2). In this way, the piston cannot rotate around its longitudinal axis.

Sur une section du piston (12) est taillée une crémaillère (15), à denture dirigée vers l'arrière de la seringue. On a section of the piston (12) is cut a rack (15), with teeth directed towards the rear of the syringe.

Sur le corps (2) est articulé, comme indiqué précédemment, un levier de commande (3) de section préférentiellement en U,pouvant être monté ainsi à rotation autour de deux demiaxes (16) fixés de chaque côté du corps (2) dans l'alignement l'un de l'autre. Le levier (3) enveloppe ainsi le corps (2), pour le moins par ses flasques (17) d'articulation. On the body (2) is articulated, as indicated above, a control lever (3) of preferably U-shaped section, which can thus be rotatably mounted around two semi-axes (16) fixed on each side of the body (2) in the alignment of each other. The lever (3) thus envelops the body (2), at least by its flanges (17) of articulation.

Entre le levier (3) et le corps (2), au niveau de la
zone de recouvrement dudit corps par le levier, est ménagée une lumière (18) dans le corps.
Between the lever (3) and the body (2), at the level of the
zone of overlap of said body by the lever, a light (18) is formed in the body.

Sur le levier (3) est monté un cliquet (19) pivotant autour d'un axe (20) fixé sur ledit levier. On the lever (3) is mounted a pawl (19) pivoting about an axis (20) fixed on said lever.

Un ressort (21) appuie d'une part sur le cliquet (19) et d'autre part sur l'intérieur du levier (3) tendant à l'éloigner du corps (2) sur lequel il bute sur un épaulement (22). A spring (21) rests on the one hand on the pawl (19) and on the other hand on the inside of the lever (3) tending to move it away from the body (2) on which it abuts on a shoulder (22) .

D'autre part, un levier (23) est monté pivotant sur un axe (24) fixé dans le corps (2). Par son extrémité (25), le levier (23) s'enclanche sur la crémaillère (15) et à son autre extrémité il comporte un bouton (26) faisant saillie hors du corps (2) et sur lequel l'utilisateur peut exercer une pression manuelle. Un ressort (27) tend à appliquer l'extrémité (25) du levier en prise avec la crémaillère (15), l'autre branche du ressort prenant appui sur la face interne du levier (3). On the other hand, a lever (23) is pivotally mounted on an axis (24) fixed in the body (2). By its end (25), the lever (23) engages on the rack (15) and at its other end it has a button (26) protruding from the body (2) and on which the user can exert a manual pressure. A spring (27) tends to apply the end (25) of the lever engaged with the rack (15), the other branch of the spring bearing on the internal face of the lever (3).

Si on presse sur le bouton (26), l'extrémité (25) se dégage de la crémaillère et entraine dans son mouvement le cliquet (19) en le dégageant donc également de la crémaillère. If the button (26) is pressed, the end (25) is released from the rack and in its movement causes the pawl (19) to be released therefore also from the rack.

Les longueurs et positions relatives du levier (23) et du cliquet (19) seront déterminées en conséquence.The relative lengths and positions of the lever (23) and the pawl (19) will be determined accordingly.

Le fonctionnement de la seringue est le suivant. The operation of the syringe is as follows.

On place pour commencer le piston à la position représentée figure 1. Pour cela on tient la seringue verticalement, l'aiguille en haut, et on presse sur le bouton (26). Le piston, dégagé du cliquet (19) et de l'extrémité (25) du levier, descend au fond du corps (2) sous le seul effet de son poids.The piston is placed at the start in the position shown in FIG. 1. For this, the syringe is held vertically, the needle at the top, and the button (26) is pressed. The piston, released from the pawl (19) and from the end (25) of the lever, descends to the bottom of the body (2) under the sole effect of its weight.

On place alors la carpule dans son support et onaccroche celui-ci sur le corps par le système à baïonnette (11). Puis on pique le patient pour l'injection. The carpule is then placed in its support and it is hooked onto the body by the bayonet system (11). Then the patient is pricked for the injection.

En pressant sur le levier (3), en fait par une simple pression répétée du pouce, comme pour un pompage, l'axe (20) se déplace par rapport aux axes (16). Le cliquet (19) pousse alors d'un cran la crémaillère (15), et donc le piston (12) qui à son tour pousse le disque caoutchouc formant le fond de la carpule. La force du doigt pressant sur le levier est donc transmise sur le disque et donc le contenu de la carpule avec multiplication, par exemple par 5. By pressing the lever (3), in fact by a simple repeated pressure of the thumb, as for a pumping, the axis (20) moves relative to the axes (16). The pawl (19) then pushes the rack (15) one notch, and therefore the piston (12) which in turn pushes the rubber disc forming the bottom of the cartridge. The force of the finger pressing on the lever is therefore transmitted to the disc and therefore the content of the cartridge with multiplication, for example by 5.

Dès que l'utilisateur lache sa pression sur le levier (3), celui-ci revient en position haute sous l'effet du ressort (21). Pendant cette opération, le levier (23) maintient par son extrémité (25) le piston en position. L'opération peut alors être répétée, le piston progressant d'une distance correspondant au pas de la crémaillère, ou à un multiple de celui-ci, à chaque pression sur le levier (3). As soon as the user releases his pressure on the lever (3), the latter returns to the high position under the effect of the spring (21). During this operation, the lever (23) maintains by its end (25) the piston in position. The operation can then be repeated, the piston progressing by a distance corresponding to the pitch of the rack, or to a multiple thereof, each time the lever (3) is pressed.

Dans la réalisation de la figure 1, l'aiguille (7) est montée sur le support (6). Le support (6) peut être solidaire du support (4) ou être monté amovible par celui-ci, par exemple par un système à baïonnette.  In the embodiment of Figure 1, the needle (7) is mounted on the support (6). The support (6) can be integral with the support (4) or be removably mounted by the latter, for example by a bayonet system.

Dans l'exemple de la figure 2, il est préférable que le support d'aiguille soit monté amovible. In the example of Figure 2, it is preferable that the needle holder is removably mounted.

Dans cette réalisation, l'aiguille est inclinée par rapport à l'axe de la seringue ce qui est plus aisé pour certaines injections. In this embodiment, the needle is inclined relative to the axis of the syringe which is easier for certain injections.

Dans ce cas, on opère comme suit
- placement de l'aiguille sur le support de carpule,
- placement de la carpule dans son support,
- placement du support de carpule sur le corps de la seringue,
- injection.
In this case, we operate as follows
- placement of the needle on the cartridge holder,
- placement of the carpule in its support,
- placement of the cartridge holder on the syringe body,
- injection.

Pour s'assurer, dans ce cas de figure, que l'aiguille pénètre bien par sa partie arrière dans la carpule, on pourra prévoir dans le support un canon (33) avec perçage conique. To ensure, in this case, that the needle penetrates well through its rear part into the cartridge, we can provide in the support a barrel (33) with conical drilling.

L'extrémité de l'aiguille glissant dans le cône de manière à ce que son extrémité arrière (9) se présente toujours sensiblement parallèlement à l'axe longitudinal de la carpule. The end of the needle sliding in the cone so that its rear end (9) is always substantially parallel to the longitudinal axis of the cartridge.

Dans la variante de mise en oeuvre de la figure 3, une languette flexible (29) fixée en (30) sur le corps (2) appuie d'une part sur le dos du levier (23'), de fonction identique au levier (23),et d'autre part sur le dos du levier (3'), de fonction identique à celle du levier (3), les maintenant, ainsi que le cliquet, en position. In the variant embodiment of FIG. 3, a flexible tongue (29) fixed at (30) on the body (2) rests on the one hand on the back of the lever (23 ′), with a function identical to the lever ( 23), and on the other hand on the back of the lever (3 '), of function identical to that of the lever (3), holding them, as well as the pawl, in position.

Lorsque l'utilisateur presse sur le levier (3'), le piston avance, par le même mécanisme que celui décrit précédemment. Dès que l'on relache la pression, le ressort (29) rappelle le levier (3') en position haute.  When the user presses on the lever (3 '), the piston advances, by the same mechanism as that described above. As soon as the pressure is released, the spring (29) returns the lever (3 ') to the high position.

Pour dégager le cliquet (19') et le levier (23') de la crémaillère du piston, il suffit de tirer sur le levier (3') au delà de sa position d'équilibre déterminée par la position de repos de la languette (29). La force (31) du levier pousse alors la face (32) du levier (23') et le fait basculer en le dégageant de la crémaillère.  To release the pawl (19 ') and the lever (23') from the piston rack, simply pull the lever (3 ') beyond its equilibrium position determined by the rest position of the tongue ( 29). The force (31) of the lever then pushes the face (32) of the lever (23 ') and causes it to tilt, releasing it from the rack.
