Description
Die Erfindung beziefei sich ^uf eine zahnärztliche Injektionspistole, die aus einem Handgriff mit einem Halter für eine Spritzampulle, eifr sn Hebel mit langem Abzugs- und kurzem Betätigungsarm für den Vorschub einer Schubstange sowie einer Rückstellfeder besteht.The invention relates to a dental Injection gun consisting of a handle with a holder for a syringe ampoule, eifr sn lever with long There is a trigger arm and a short actuating arm for advancing a push rod and a return spring.
Für veterinärärztliche Zwecke sind derart ausgebildete Injektionspistolen bekannt (brit. PS 11 98 214).Injection guns designed in this way are known for veterinary purposes (British PS 11 98 214).
Bei dieser bekannten Injektionspistole dient die Schubstange zur Betätigung des Kolbens der Spritzampulle. Der Betätigungsarm des Hebels steht über einer Rast mit der als Zahnstange ausgebildeten runden Schubstange in Wirkverbindung. Wegen der Drehmöglichkeit der Schubstange ist der Vorschub bei dieser Injektionsspritze nicht gewährleistet. Es ist weiter eine, auch motorisch angetriebene Vorrichtung zum portionierten Ausspritzen bekannt (Schweizer Patentschrift 4 49 180), bei der eine mit dem Betätigungshebel kraftschlüssig verbundene Lochscheibe die von einer Schubstange durchsetzt ist zur Mitnahme der Schubstange diese entgegen Federwirkung klemmend erfaßt.In this known injection gun, the push rod is used to actuate the piston of the injection ampoule. The operating arm of the lever is above one Latches in operative connection with the round push rod designed as a rack. Because the push rod can be rotated, the feed rate is lower Injection syringe not guaranteed. There is also a motor-driven device for portioned spraying known (Swiss patent 4 49 180), in which a perforated disc positively connected to the actuating lever is used by a Push rod penetrated is grasped by clamping against spring action for driving the push rod.
Diese Vorrichtung ist als Injektionspistole völlig ungeeignet, u. a. weil sich der Abzug an der Außenseite des Griffs befindet.This device is completely unsuitable as an injection gun, inter alia. because the trigger is on the outside of the handle.
Der Erfindung liegt die Aufgabe zu Grunde, eine für zahnärztliche Zwecke geeignete Injektionsspritze zu schaffen, die gewichtsleicht ist und bei der der Vorschub der Schubstange mit einfachen Mitteln gesichert ist.The invention is based on the object of providing an injection syringe suitable for dental purposes create that is light in weight and in which the advance of the push rod is secured with simple means.
Zur Lösung dieser Aufgabe werden Merkmale der beiden als vorbekannt beschriebenen Spritzen so kombiniert, daß die Lochscheibe unmittelbar auf der als Schubstange dienenden Kolbenstange sitzt und mit dem kurzen Betätigungsarm des Hebels über ein einziges an ihm angeordnetes Kraftübertragungsteil in Wirkverbindung steht.To solve this problem, features of the two syringes described as previously known are as follows combined that the perforated disc sits directly on the piston rod serving as a push rod and with the short actuating arm of the lever is in operative connection via a single force transmission part arranged on it.
Damit die Schubstangenbewegung gleichmäßig verläuft, sind gemäß einem weiteren Gedanken der Erfindung zwei parallel zur Schubstange am Pistolenlauf angeordnete Blattfedern vorgesehen, die mit radial der Schubstange aufstehenden Stiften die Bewegung derselben bremsen. In order for the push rod movement to run smoothly, two leaf springs arranged parallel to the push rod on the gun barrel are provided according to a further concept, which brake the movement of the push rod with pins protruding radially from the push rod.

Eine gleiche Blattfeder ist auf der in der Zeichnung nicht sichtbaren entgegengesetzten Seite des Trägers 3 angeordnet.A leaf spring 14 is attached to the side of the carrier 3 and has a pin 15 at one end, the the push rod 6 is seated radially. The same leaf spring is not visible in the drawing opposite side of the carrier 3 arranged.
4.7 Die Wirkungsweise der vorstehend beschriebenen zahnärztlichen Injeklionsspritzpistole ist wie folgt:4.7 The operation of the dental injection gun described above is as follows:
Die Schubstange 6 wird so weit wie möglich zurückgeschoben, indem sie am Bedienungsknopf 8 zurückgezogen wird, sie gleitet dabei in der Scheibe 5. InThe push rod 6 is pushed back as far as possible by pressing the control button 8 is withdrawn, it slides in the disc 5. In dieser Stellung der Schubstange 6 läßt sich die Spritzampulle 1 leicht in den Halter 2 einsetzen, nachdem die Bajonett- oder Schraubverbindung 4 gelöst und anschließend wieder angeschraubt wurde. Die mit der Injektionsflüssigkeit gefüllte und mit derthis position of the push rod 6 can be the Slightly insert the injection ampoule 1 into the holder 2 after the bayonet or screw connection 4 was loosened and then screwed back on. The one filled with the injection liquid and with the Injektionsnadel versehene Spritzampulle 1 wird dann in dem Halter 2 durch Betätigung der Verbindungsvorrichtung 4 festgelegt, indem die letztere um einen kleinen Winkel gedreht wird. Danach ist die Injektionspistole fertig zur Ausführung einer Injektion.Injection needle-provided injection ampoule 1 is then fixed in the holder 2 by actuating the connecting device 4, the latter by a small Angle is rotated. The injection gun is then ready to carry out an injection.
Zur Ausführung des eigentlichen Injektionsvorgangs wird die Injektionspistole in einer Hand so gehalten, daß der Daumen an einer Seite des Handgriffs 16 und der kleine Finger und der Ringfinger an der anderen Seite in den Ausnehmungen 24 unterhalb des Vorsprungs 22 liegen. In dieser Handstellung wird der Abzugsarm 12 mit dem Zeigefinger und dem Mittelfinger der gleichen Hand zurückgezogen, wobei der Zeige- und Mittelfinger vor dem Abzugsarm 12 oberhalb des Vorsprungs 22 am Bügel liegen. Auf diese Weise wird die Schubstange 6 schrittweise vorgeschoben und, da das vordere Ende der Schubstange 6 auf der Rückseite des Kolbens der Spritzampulle I einwirkt, wird der Kolben der Spritzampulle vorgeschoben; dies bewirkt die Einsprit- To carry out the actual injection process, the injection gun is held in one hand so that the thumb on one side of the handle 16 and the little finger and ring finger on the other side are in the recesses 24 below the projection 22 . In this hand position, the trigger arm 12 is withdrawn with the index finger and the middle finger of the same hand, the index and middle finger lying in front of the trigger arm 12 above the projection 22 on the bracket. In this way, the push rod 6 is advanced step by step and, since the front end of the push rod 6 acts on the back of the piston of the injection ampoule I, the piston of the injection ampoule is advanced; this causes the injection

Durch jede Betätigung des Abzugsarmes 12 wird die Schubstange 6 um einen Schritt vorgerückt, wobei die Länge der Schritte durch die Blattfedern 14 und die Bemessung der Scheibe 5 bestimmt istInjection liquid from the injection ampoule 1 in the gums. Each time the trigger arm 12 is actuated, the push rod 6 moves one step advanced, the length of the steps being determined by the leaf springs 14 and the dimensioning of the disc 5 is determined
Die Bewegung der Scheibe 5 wird durch die beschriebene Torsionsfeder unterstützt Nach jeder auf den Abzugsarm 12 ausgeübten Zugbewegung wird derselbe duich die Blattfeder 17 in seine vordere Stellung zurückbewegt Auf diese Weise wird ein gleichmäßiger allmählicher Injektionsvorgang gewährleistet Die Blattfedern 14 haben im wesentlichen die Aufgabe, die Vorwärtsbewegung der Schubstange 6 zu bremsen, während die Torsionsfeder dazu dient, die Scheibe 5 nach hinten zu drücken. Der Längsschlitz 22 in dem Halter 2 gestattet die Beobachtung der Bewegung des Kolbens der Spritzampulle. Das Ende des Hubwegs dieses Kolbens kann jedoch auch an Hand des Bedienungsknopfes 8 ermittelt werden, der den Grad des Eindringens der Schubstange 6 anzeigt Nachdem auf diese Weise festgestellt wurde, daß der Kolben der Spritzampulle das vordere Ende seines Hubweges erreicht hat, ist der Injektionsvorgang beendet; die Injektionspistole wird beiseitegelegt Die Spritzampulle 1 kann aus der Injektionspistole nach Lösen der Verbindung 4, wie oben beschrieben, entnommen werden.The movement of the disc 5 is supported by the torsion spring described after each on the pulling movement exerted on the trigger arm 12 is the same duich the leaf spring 17 in its front Position moved back This ensures a smooth, gradual injection process The leaf springs 14 essentially have the task of moving the push rod 6 forward brake while the torsion spring serves to push the disc 5 backwards. The longitudinal slot 22 in the holder 2 allows the movement of the plunger of the injection ampoule to be observed. The end of the stroke this piston can, however, also be determined by means of the control button 8, which indicates the degree of the penetration of the push rod 6 after it has been determined in this way that the piston of the The injection ampoule has reached the front end of its stroke, the injection process is finished; the Injection gun is put aside. The injection ampoule 1 can be removed from the injection gun after loosening the Compound 4 as described above can be removed.
