Chirurgischer Knotenschieber mit Spanngabel ZusammenfassungSurgical Knot Pusher with Tension Fork Summary

Die Erfindung betrifft die Umgestaltung eines an sich bekannten chirurgischen Knotenschiebers für den Einsatz insbesondere bei der operativen Pelviskopie. Der Knotenschieber zum einmaligen Gebrauch erhält neben dem Fadenkanal einen zweiten Kanal zur Durchführung eines Drahtes, der an seiner Spitze zu einer Gabel geformt ist und damit die Aufspannung der Fadenschlinge erlaubt. 15The invention relates to the modification of a known surgical knot pusher for use in particular in operative pelviscopy. In addition to the thread channel, the single-use knot pusher has a second channel for passing through a wire, which is shaped into a fork at its tip and thus allows the thread loop to be stretched. 15

Stand der TechnikState of the art

Die heute bekannten Knotenschieber zum einmaligen Gebrauch bestehen aus einem Kunststoffstab, der der Länge nach durchbohrt ist. Der Faden mit der bereits konfektionierten Schlinge ist durch diese Bohrung gezogen. Nach dem Einführen der Schlinge durch das Trokar und ihrer Plazierung wird durch Ziehen am Fadenende die Schlinge geschlossen. Da der Faden lose am Knotenschieber hängt, ist die Plazierung der Schlinge und ihre Of fnung, um sie über das zu vernähende Ende zu schieben, äußerst mühsam. Da für die eine Hand nur eine Faßzange zur Verfügung steht während die andere den Knotenschieber führt, kann die Schlinge eigentlich nmr mit Hilfe der Schwerkraft geöffnet werden, d.h. indem sie frei hängend verarbeitet wird. Das schränkt 0 die Verwendbarkeit solcher vorkonfektionierter Schlingen stark ein.The knot pushers known today for single use consist of a plastic rod that is drilled lengthwise. The thread with the loop already made up is pulled through this hole. After the loop has been inserted through the trocar and placed, the loop is closed by pulling on the end of the thread. Since the thread hangs loosely on the knot pusher, placing the loop and opening it to push it over the end to be sutured is extremely laborious. Since only a pair of forceps is available for one hand while the other guides the knot pusher, the loop can actually only be opened with the help of gravity, i.e. by processing it while it is hanging freely. This greatly limits the usability of such prefabricated loops.

Erfindunginvention

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, den Knotenschieber so umzugestalten, daß durch eine zweite parallele Bohrung ein Draht geführt werden kann, der am Ende zu einer Gabel geformt ist, um damit die Fadenschlinge aufzuspannen, wie es in Fig. 1 dargestellt ist. F ist die Fadenschlinge und G bezeichnet die Spanngabel. Wenn jetzt die so gespannte Faden-The present invention is based on the task of redesigning the knot pusher so that a wire can be guided through a second parallel hole, which is shaped into a fork at the end in order to tension the thread loop, as shown in Fig. 1. F is the thread loop and G denotes the tensioning fork. If the thread is now tensioned in this way,

schlinge durch dc.s Trokar eingeführt ist, kann die andere Hand mit Hilfe einer Faßzange die Schlinge leicht zu einem Dreieck
aufspannen und damit praktisch in jeder Lage die Schlinge plazieren. Jetzt kann die Spanngabel zurückgezogen werden, wo sie durch das abgeschrägte Ende des Knotenschiebers soweit verdeckt wird, da/3 das Schließen der Schlinge nicht behindert wird.loop is inserted through dc.s trocar, the other hand can easily use a grasping forceps to form the loop into a triangle
and thus place the loop in practically any position. Now the tensioning fork can be pulled back, where it is covered by the bevelled end of the knot slider so that the closing of the loop is not hindered.
