AIGUILLE A INJECTION PERFORANTE ET NON OBSTRUABIE DISPOSITIF DE
FABRICATION:
La présente inveitien s'inscrit dais le demaine des aiguilles à injection de liquide, ai particulier les aiguilles permettant d'injecter un anesthésique, ceci en edentestametologie.DESCRIPTION
PERFORATING, NON-OBSTRUCTED INJECTION NEEDLE DEVICE
MANUFACTURING:
The present invention is part of the need for liquid injection needles, in particular needles for injecting an anesthetic, this in edentestametology.
Pour injecter les anesthésiques, les chirurgiens dentistes et stamoto- logistes oit à leur disposition des seringuas et des aiguilles classiques, que l'en trouve dais le commerce. To inject the anesthetics, dental surgeons and stamotologists use conventional syringes and needles, which can be found in the trade.
L'extrémité de ces aiguilles se présente cemme le meistre les figures "1 et 2" de la planche 1/2. The ends of these needles appear as shown in Figures 1 and 2 of Plate 1/2.
Le problème particulier queent à résoudra ces praticiens est la né cessité, dans l'anesthésie dite "Intraseptale", d'injecter à travers la corticale de l'es, ceci afin d'obtenir, avec moins de produit une anesthésie plus efficace, plus rapide et avec un inconfort beaucoup moindre pour le patient. The particular problem that these practitioners will solve is the need, in so-called "Intraseptal" anesthesia, to inject through the cortex of the ES, this in order to obtain, with less product, a more effective anesthesia, more fast and with much less discomfort for the patient.
Les aiguilles et les seringues classiques ne permettait de perforer la corticale qu'a son endroit le plus faible et an se servait de l'aiguille comme d'un peiçon. Conventional needles and syringes only made it possible to perforate the cortex at its weakest point and used the needle as a puncher.
D'eu l'apparition de trois difficultés qui restreignent besucoup le champ d'utilisation de cette technique. Hence the appearance of three difficulties which besucoup restrict the field of use of this technique.
a) difficulté de localisation du point d'injectien qui sera le plus
facilement perforé
b) forte chance peur que l'aiguille s'obstrue, celle-ci servant d'em-
perte pièce.a) difficulty in locating the injection point which will be the most
easily perforated
b) high chance that the needle will become blocked, the needle serving as a
piece loss.
c) nécessité de travailler es farce, aussi bien à la perforation qu'à
l'injection, ce qui doue. des aiguilles qui se tardent et peur le
patient une sensation de tensien très désagréable.c) need to work stuffing, both for perforation and
injection, which is good. needles that are late and fear the
patient a very unpleasant feeling of tension.
La première difficulté a été résolue par la création d'un injecteur particulier, (Brevet il 7913305) qui permet par la mise en rotation de l'ai- guille d'injection de perforer la corticale osseuse et ceci sur une épais- seur de zero à deux mm, ce qui accroît énermement le nommre de points d'injection possibles. The first difficulty was solved by the creation of a particular injector, (Patent il 7913305) which allows by rotation of the injection needle to perforate the bone cortex and this on a thickness of zero two mm, which greatly increases the number of possible injection points.
La troisième difficulté est résolue en mSme temps car la rotation de l'aiguille évite de travailler en force et permet d'atteindre l'os vraiment spongieux ce qui raid l'injection très facile. The third difficulty is solved at the same time because the rotation of the needle avoids working in force and makes it possible to reach the really spongy bone which makes the injection very easy.
Reste la deuxième difficulté, en utilisait les aiguilles du commerce les performances de l'injecteur restent moyennes car une partie des aiquilles
s'obstenuent. The second difficulty remains, using commercial needles, the injector performance remains average because part of the needles
obstruct themselves.
Pour éviter cet ecueil il est nécessaire de faire tourner l'ai- guille très rapidement ( 6 à 7 000 teurs/minute ) ce qui est désa agréable pour le patient et risque de provoquer un échauffement de la parois osseuse. To avoid this pitfall, it is necessary to rotate the needle very quickly (6 to 7,000 tours / minute) which is unpleasant for the patient and risks causing the bone wall to heat up.
La présenta invention consiste donc à fabriquer des aiguillas adaptées à la rotation et permettait une perforation sans s'obstruer. The present invention therefore consists in manufacturing needles adapted to rotation and allowed a perforation without obstructing.
Les aiguilles classiques du commerce se présentent comme le mentre la figura ( 1 et 2 planche 1/2 ). The classic commercial needles are presented like the mentre la figura (1 and 2 plate 1/2).
Les nouvelles aiguilles se présentant comme sur les figure ( 3 et 4 planche 1/2). The new needles appearing as in the figure (3 and 4 board 1/2).
1) su du dessus le biseau reste le même excepte que la lumière
de l(aiguille an lieu d'être circulaire se trouve applatie
figure 3 coupe i D
2) ltcstrdmitd du biseau est recentrée sur l'axe de l'aiguille
figure 4
3) Le diamètre de l'extrémité selon ce profil ( figure 4) est diminué de moitié ce qui retrecit d'autant le lumiére de l'aiguille, et forme un décrochement dans la pareil extérieure de l'aiguille
4) le diamètre extérieur maximum de l'aiguilla est conservé
en peut voir que cette aiguille nouvelle solutionne le probleme de la perforation et de l'obstruction par les améliorations suivantes.1) from above the bevel remains the same except as the light
of the needle instead of being circular is flattened
figure 3 section i D
2) ltcstrdmitd of the bevel is centered on the axis of the needle
figure 4
3) The diameter of the end according to this profile (FIG. 4) is halved, which narrows the light of the needle all the more, and forms a recess in the outside of the needle
4) the maximum outside diameter of the needle is retained
can see that this new needle solves the problem of perforation and obstruction by the following improvements.
1) le biseau étant recentré sur l'axa de l'aiguille, celui-ci
travaille mieux sans baleurd, la vitesse nécessaire à la
perforation se trouve réduite à 1 000 ou 2 QQQ tours minute, d
d'ou diminution du désagrement peur le patient et du ris
que d'échauffement de la parois essuse.1) the bevel being centered on the axis of the needle, this one
works better without baleurd, the speed necessary for the
perforation is reduced to 1000 or 2 QQQ revolutions per minute, d
or decrease the inconvenience for the patient and the risk
that heating of the wipe walls.
2) La surface de la lumière était divisée environ par 4, le
risque d'obstruction est divisé lui même par 4 car le ve-
lume des copeaux formés reste le même.2) The surface of the light was divided approximately by 4, the
risk of obstruction is itself divided by 4 because the ve-
the amount of shavings formed remains the same.
3) le décrochement dans le profil de l'aiguilla crée par rap
port au trou formé un espace où peuvent se loger les copeaux
formés lors de la perforation. Ce volume disponible pour
les copeaux n'existe pas dans las aiguilles classiques.3) the drop in the profile of the needle created by rap
port to the hole formed a space where the shavings can be housed
formed during perforation. This volume available for
shavings do not exist in conventional needles.
4) la diminution de la surface de la lumière diminue d'autant
le débit de l'injection ce qui rend l'injection moins
brutale donc moins douloureuse.4) the decrease in the surface of the light decreases correspondingly
the injection rate which makes the injection less
brutal therefore less painful.
Les schémas de la planche 1/2 sent doums à titre indicatif, les diamètres des aiguilles variant, seul le principe reste valable. The diagrams of the 1/2 sheet feel doums for information, the diameters of the needles varying, only the principle remains valid.
Le moyen de réalisation de cette aiguille est une presse spéciale ( planche 2/2 )
Ce shema n'est aussi qu'indicatif car nous avons veleutai- rement supprimé les vis d'assemblage et de réglage, peur que le dessin reste compréhensif
Cette presse se composa de tris parties principales
1) une partie C qui est un perte aiguilla dans lequel eu
immobilise l'aiguille dans la position voulue et a dis
tance voulue des formes D et B ( longueur du decrechement 3
2) une partie D qui est une forma solidaire du perte aiguille C
Cette forme a peur caractéristique de comporter une saignée
de largeur égale au diamètre de l'aiguille ceci afin d'éviter
lors de la compression une augmentation de cette dimension. The means of production of this needle is a special press (plate 2/2)
This shema is also only indicative because we quickly removed the assembly and adjustment screws, fear that the drawing remains comprehensive
This press consisted of three main parts
1) part C which is a needle loss in which
immobilizes the needle in the desired position and says
desired size of forms D and B (length of the decrease 3
2) a part D which is a forma integral with the loss of needle C
This form is typically afraid of having a bleeding
of width equal to the diameter of the needle this in order to avoid
during compression an increase in this dimension.
D'autre part le fond do cette saignée est décalée par rap-
port à lave de 1 t aiguille ce qui donne le décrochement
dans le profil de l'aiguille.On the other hand, the bottom of this groove is offset with respect to
port of lava of 1 t needle which gives the detachment
in the needle profile.
3) une partie B qui est une forme symétrique de la forme 9 mais
amovible.3) a part B which is a symmetrical form of the form 9 but
removable.
L'ensemble fonctionne de la manière suivante. On introduit l'aiguille A dans le perte aiguille C le biseau de celle ci étant dirigé vers le fend de la saignée. La forme B est descendue sur la forme D, l'ensemble est comprimé par un moyen mécanique quelconque. The assembly works as follows. The needle A is introduced into the needle loss C, the bevel thereof being directed towards the split of the groove. Form B is lowered onto Form D, the assembly is compressed by any mechanical means.
Les deux formes sont séparées et l'aiguille est extraite de perte aiguilla C.The two forms are separated and the needle is extracted from needle loss C.
I1 faut préciser que la ferme du profil de l'aiguille est déterminé par le fond de la saignée, pratiquée dans les fermas D et B et que le profil indiqué sur le schéma n'est pas unique et limitatif. It should be noted that the firmness of the profile of the needle is determined by the bottom of the groove, made in fermas D and B and that the profile indicated on the diagram is not unique and limiting.
Cette invention ( moyen de fabrication ) peut-être appliquée industriellement par l'inclusion de cette presse dans une chaîne de fabrication d'aiquillesclassiques. This invention (means of manufacture) can be applied industrially by the inclusion of this press in a production line of conventional needles.
Ceci permet d'obtenir des aiguillas de forma nouvelle adaptées à la perforation qui peuvent, utilisées avec l'injecteur approprie permettra de perforer la corticale osseuse sans s'obstruer et drin- jecter un anesthésique dans l'es spongieux ceci en odontostamotologie
L'ensemble injecteur et aiguilla Fend l'anesthésie dite "intraseptale" d'application beaucoup plus facile et agréable pour le patientcomme peur le praticien. This makes it possible to obtain new forma needles adapted to the perforation which can, used with the appropriate injector, will make it possible to perforate the bone cortex without obstructing and injecting an anesthetic into the cancellous es this in odontostamotology
The injector and referral unit makes the so-called "intraseptal" anesthesia much easier and more pleasant to apply to the patient as the practitioner is afraid.
