Description
AT 000 824 UlAT 000 824 Ul
Die Erfindung betrifft eine Arbeitskanüle für die Arthroskopie , insbesondere der Schulter und des Knies, bestehend aus einem Rohr und einem darin geführten entfernbaren Verschlußzapfen (Trokar).The invention relates to a working cannula for arthroscopy, in particular the shoulder and the knee, consisting of a tube and a removable closure plug (trocar) guided therein.
Bei einer bekannten Einrichtung, welche von der Firma Arthrex vertrieben wird, ist der Verschlußzapfen mit einem stumpfen Vorderende versehen, da eine Spitze zu Verletzungen insbesondere auch von Nerven führen könnte, während ein stumpfer Zapfen durch das Muskelgewebe gedrückt werden kann.In a known device, which is sold by the Arthrex company, the locking pin is provided with a blunt front end, since a tip could lead to injuries, particularly to nerves, while a blunt pin can be pressed through the muscle tissue.
Aus SU-Al 15 21 465 ist andererseits bereits eine aus Trokarhülse und Trokar bestehende Einrichtung bekannt geworden, wobei die Trokarhülse im distalen Endbereich ein Außengewinde aufweist, welches durch das Gewinde der Trokarspitze fortgesetzt wird.From SU-Al 15 21 465, on the other hand, a device consisting of trocar sleeve and trocar has already become known, the trocar sleeve having an external thread in the distal end region, which is continued by the thread of the trocar tip.
Bei der erstgenannten Ausführung ist die Zielsicherheit der Einrichtung relativ gering. Bei einer mit einem Gewinde versehenen Arbeitskanüle kommt es andererseits kritisch darauf an, sofort die richtige Lage im Gelenk zu finden, da ein mehrmaliges Einschrauben des scharfkantigen Gerätes unbedingt zu vermeiden ist.In the first-mentioned embodiment, the target security of the device is relatively low. In the case of a threaded working cannula, on the other hand, it is critical to find the correct position in the joint immediately, since repeated screwing in of the sharp-edged device must be avoided.
Die Erfindung garantiert ein zielsicheres Einführen der Arbeitskanüle dadurch, daß der Verschlußzapfen eine durchgehende zentrale Bohrung zur Aufnahme eines Führungsdrahtes aufweist.The invention guarantees a precise insertion of the working cannula in that the closure pin has a continuous central bore for receiving a guide wire.
An sich scheint es paradox, den Verschlußzapfen (Trokar), dessen Aufgabe das Verschließen der Trokarhülse ist, selbst wieder als Hülse auszubilden. Die zentrale Bohrung des Verschlußzapfens, welche erfindungsgemäß vorgesehen wird, ist während des Einführens der Arbeitskanüle jedoch sicher durch den Führungsdraht verschlossen. 2 AT 000 824 UlIn itself, it seems paradoxical to design the sealing plug (trocar), the function of which is to close the trocar sleeve, as a sleeve again. The central bore of the closure pin, which is provided according to the invention, is, however, securely closed by the guide wire during the insertion of the working cannula. 2 AT 000 824 Ul
Einzelheiten der Erfindung werden anschließend anhand der Zeichnungen erläutert. In diesen stelltDetails of the invention are subsequently explained with reference to the drawings. In this poses

Fig. 2 zeigt die Einrichtung nach Fig. 1 im zusammengebauten Zustand,FIG. 2 shows the device according to FIG. 1 in the assembled state,
Fig. 3 ist ein teilweiser Schnitt durch Fig. 2, undFig. 3 is a partial section through Fig. 2, and
Fig. 4 ein vollständiger Längsschnitt der Einrichtung nachFig. 4 shows a complete longitudinal section of the device
Fig. 2 bzw. Fig. 3.2 and 3.
Wesentlicher Teil einer Arbeitskanüle für die Arthroskopie ist ein Rohr 1, welches im vorliegenden Fall mit einem scharfkantigen Gewinde 2 versehen ist. Am äußeren Ende befindet sich ein Anschlußstutzen 4, durch den beispielsweise eine Flüssigkeit eingepreßt werden kann. £>An essential part of a working cannula for arthroscopy is a tube 1, which in the present case is provided with a sharp-edged thread 2. At the outer end there is a connecting piece 4 through which, for example, a liquid can be injected. £ >
Beim Einführen des Rohres 1 in ein Gelenk, insbesondere in das Schultergelenk, ist das Rohr 1 durch einen Verschlußzapfen 5 ausgefüllt, dessen mit einem Gewinde 8 versehene Spitze durch das Rohr 1 ragt und dessen Gewinde derart fortsetzt, daß der Durchmesser zur Spitze hin rasch abnimmt. Ein Ansatz 7 an der Außenseite des Verschlußzapfens 5 rastet in eine Erweiterung 3 des Rohres ein, wenn der Verschlußzapfen 5 ganz in das Rohr 1 eingeführt ist. Dadurch kann, wie aus Fig. 3 ersichtlich ist, das Rohr 1 mittels des Drehgriffes 6 eingeschraubt werden, welcher am Verschlußzapfen 5 angeordnet ist. Für die Erfindung wesentlich ist die zentrale Bohrung 9 im Verschlußzapfen 5, welche in Richtung des Drehgriffes 6 in eine Erweiterung 10 übergeht.When the tube 1 is inserted into a joint, in particular into the shoulder joint, the tube 1 is filled by a locking pin 5, the threaded tip 8 of which protrudes through the tube 1 and the thread of which continues in such a way that the diameter decreases rapidly towards the tip . An extension 7 on the outside of the locking pin 5 snaps into an extension 3 of the tube when the locking pin 5 is fully inserted into the tube 1. As a result, as can be seen from FIG. 3, the tube 1 can be screwed in by means of the rotary handle 6, which is arranged on the locking pin 5. Essential for the invention is the central bore 9 in the locking pin 5, which merges into an extension 10 in the direction of the rotary handle 6.
Der Durchmesser der Bohrung 9 beträgt etwa 1 mm, wodurch ein sicherer Halt für einen Führungsdraht gegeben ist. Als sicherer Führungsdraht kommt insbesondere ein als Kirsch-nerdraht bekannter zugespitzter Draht aus Federstahl in Be- 3 AT 000 824 Ul tracht, welcher elastisch verformbar ist und hohe Bruchfestigkeit aufweist.The diameter of the bore 9 is approximately 1 mm, which provides a secure hold for a guide wire. As a safe guidewire, in particular a pointed wire made of spring steel known as Kirsch ner wire is used, which is elastically deformable and has high breaking strength.
Bei einer Operation wird zunächst ein Arthroskop eingeführt und dann in dessen Gesichtsfeld der Führungsdraht an die gewünschte Stelle eingestochen, über den Führungsdraht wird nun mit durch den Führungsdraht gesichertem Zielort die aus Rohr 1 und VerschluBzapfen 5 (Trokarhülse und Trokar) bestehende Einrichtung unter Drehen des Drehgriffes 6 eingeschraubt. Anschließend werden der Führungsdraht und der Verschlußzapfen 5 herausgezogen, wobei das Gewinde 2 das Rohr 1 in seiner Position hält, sodaß nun durch das Rohr 1 die gewünschten Manipulationen vorgenommen werden können. 4During an operation, an arthroscope is first inserted and then the guidewire is inserted into the field of vision in the field of vision, then the device consisting of tube 1 and locking pin 5 (trocar sleeve and trocar) is turned over the guidewire with the destination secured by the guidewire while turning the rotary handle 6 screwed in. Then the guide wire and the locking pin 5 are pulled out, the thread 2 holding the tube 1 in its position, so that the desired manipulations can now be carried out through the tube 1. 4th
