Description

  

   <Desc/Clms Page number 1> 
 



  Instrument für Kieferhöhlenpunktion 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Das erfindungsgemässe Instrument besteht aus einer Punktionsnadel   1,   einem Metallröhrchen 2 und einer Kanüle 3. Die Punktionsnadel 1 setzt sich zusammen aus einer Hohlnadel   l* und   einer in diese einführbaren Nadel l", die im eingeschobenen Zustand mit der Nadel   l'abschliesst   und mit ihr gemeinsam eine Schnittfläche 4 bildet. Beide Nadeln besitzen je einen Griff 5 bzw. 6, wobei im zusammengesetzten Zustand der Griff 6 an den Griff 5 anschliesst. Beim gebrauchsfertigen Instrument ist auf die Hohlnadel   1,   an den Griff 6 derselben anstossend, das Metallröhrchen 3 und im Anschluss an dieses die Kanüle 2 aufgeschoben. Letztere ist am vorderen Ende 7 konisch verjüngt und reicht bis an den Beginn der Schnittfläche 4 der Punktionsnadel 1.

   Das sich am Metallröhrchen 3 abstützende Ende 8 der Kanüle 2 ist trompetenförmig verbreitert. Zwischen diesen beiden Enden befindet sich eine ringförmige Verdickung 9. 



     Die Benutzung des erfindungsgemässen Instrumentes erfolgt in   der Weise, dass nach üblicher Anästhesie des unteren Nasenganges und der Durchstechungsstelle die zusammengesetzte Punktionsnadel 1 mit dem Röhrchen 3 und der Kanüle 2 in den unteren Nasengang eingeführt und die mediale Kieferhöhlenwand an der üblichen Stelle durchstochen wird. Dadurch gelangt die Kanüle 2 mit ihrem vorderen Ende in die Kieferhöhle und dringt so weit vor, bis die ringförmige Verdickung 9 innerhalb der Knochenwand zu liegen kommt. Hierauf wird die Punktionsnadel 1 herausgezogen, wobei die Kanüle 2 auf ihrem Platz mittels des Röhrchens 3 zurückgehalten wird.

   Nach diesem Eingriff verbleibt die Kanüle 2 in jener Lage, in der ihr inneres Ende in die Kieferhöhle hineinragt und das äussere trichterförmige Ende unterhalb des vorderen Endes der Nasenmuschel gut zu sehen ist. Die ringförmige Verdickung 9 sichert insbesondere nach Wiederanschwellen der Schleimhaut einen guten Sitz der Kanüle und verhindert, dass diese aus der Knochenwand herausrutscht. Ein Wandern der Kanüle in die Kieferhöhle wird durch die trichterförmige Ausweitung des Endes 8 verhindert. 



   Die Kanüle 2 besteht zweckmässig aus nichtrostendem Metall und kann in der Nase ohne Schaden für den Knochen oder die Schleimhaut und ohne vom Patienten unangenehm empfunden zu werden, mehrere Wochen lang bis zum vollständigen Abfluss des Eiters verbleiben. Die Heilung der Entzündung wird durch wiederholte Spülungen beschleunigt, die ohne Lokalanästhesie nach Einführen einer dünneren Punktionsnadel in die in der Nase sitzende Kanüle vom Arzt durchgeführt werden können. Da die Nadel während der Spülung vom Arzt gehalten werden muss, ist es zweckmässig, am Ansatz der Nadel einen weichen biegsamen Gummischlauch zu montieren, damit die Kanüle keinen   Liberflüssigen   Bewegungen ausgesetzt wird. Nach Abklingen der Entzündung und Aufhören der Sekretion wird die Behandlung beendet und die Kanüle aus der Nase entfernt.

   Zu diesem Zwecke wird nach Vornahme einer Lokalanästhesie die Kanüle, welche nach Abschwellen der Schleimhaut nur mehr durch den Wulst 9 gehalten ist, mit einer Pinzette erfasst und herausgezogen. 



    PATENTANSPRÜCHE :    
1. Instrument für Kieferhöhlenpunktion, mit einer Punktionsnadel, auf welche eine Kanüle aufgeschoben ist, dadurch gekennzeichnet, dass die Kanüle zur Sicherung ihres Sitzes in der Knochenwand an ihrer Aussenfläche mit einer vorzugsweise als Ringwulst (9) ausgeführten Verdickung versehen ist.

  Instrument for maxillary sinus puncture
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   The instrument according to the invention consists of a puncture needle 1, a metal tube 2 and a cannula 3. The puncture needle 1 is composed of a hollow needle 1 * and a needle 1 "which can be inserted into the hollow needle 1" and terminates with the needle 1 'and with it jointly forms a cut surface 4. Both needles each have a handle 5 or 6, and in the assembled state the handle 6 adjoins the handle 5. In the ready-to-use instrument, the hollow needle 1 and the handle 6 are abutted by the metal tube 3 and subsequently the cannula 2. The latter is conically tapered at the front end 7 and extends to the beginning of the cut surface 4 of the puncture needle 1.

   The end 8 of the cannula 2 supported on the metal tube 3 is widened in the shape of a trumpet. An annular thickening 9 is located between these two ends.



     The instrument according to the invention is used in such a way that, after usual anesthesia of the lower nasal passage and the puncture site, the assembled puncture needle 1 with the tube 3 and the cannula 2 are inserted into the lower nasal passage and the medial maxillary sinus wall is pierced at the usual point. As a result, the front end of the cannula 2 enters the maxillary sinus and penetrates until the ring-shaped thickening 9 comes to lie within the bone wall. The puncture needle 1 is then withdrawn, the cannula 2 being held back in place by means of the tube 3.

   After this operation, the cannula 2 remains in that position in which its inner end protrudes into the maxillary sinus and the outer funnel-shaped end can be clearly seen below the front end of the turbinate. The annular thickening 9 ensures a good fit of the cannula, particularly after the mucous membrane swells again, and prevents it from slipping out of the bone wall. Migration of the cannula into the maxillary sinus is prevented by the funnel-shaped expansion of the end 8.



   The cannula 2 is expediently made of stainless metal and can remain in the nose for several weeks until the pus has completely drained without damage to the bone or the mucous membrane and without the patient feeling uncomfortable. The healing of the inflammation is accelerated by repeated irrigation, which can be carried out by the doctor without local anesthesia after inserting a thinner needle into the cannula in the nose. Since the needle must be held by the doctor during irrigation, it is advisable to mount a soft, flexible rubber tube at the attachment point of the needle so that the cannula is not exposed to unnecessary movements. After the inflammation has subsided and the secretion has stopped, the treatment is ended and the cannula is removed from the nose.

   For this purpose, after local anesthesia has been performed, the cannula, which is only held by the bulge 9 after the swelling of the mucous membrane has subsided, is grasped with tweezers and pulled out.



    PATENT CLAIMS:
1. Instrument for maxillary sinus puncture, with a puncture needle onto which a cannula is pushed, characterized in that the cannula is provided on its outer surface with a thickening preferably designed as an annular bead (9) to secure its seat in the bone wall.
