Abstract

The flexible reflection instrument (1) is used during a surgical operation for moving the inner organs and vessels in the patient's body. It has an attachment which keys it against rotation in the instrument channel of the surgical vessel closing instrument. The attachment has a slit to guide the suture on closing the knot, and a sharp cutter to sever the suture. The anti-rotation key lock is a slit, as extensions into the hollow zone of the attachment.

Description

Das Anlegen von Unterbindungen und Nähten mit biegsamen Spiegelungsinstrumenten für innere Körperhöhlen wird durch die Erfindung vereinfacht, indem 1. jedes herkömmliche Fadenmaterial verwendet werden, 2. der Knoten außerhalb des Körpers mit der Hand gelegt wird, 3. eine Vorrichtung zum Spannen des Knoten vorhanden ist und daß 4. eine Vorrichtung zum Abtrennen des Fadens vorgesehen ist.The creation of ties and seams with flexible Mirroring instruments for inner body cavities is provided by the invention simplified by 1. using any conventional thread material, 2. the Knot is placed outside the body by hand, 3. a device for Tensioning of the knot is present and that 4. a device for severing the Thread is provided.

Beschreibung der ErfindungDescription of the invention

Als Stand der Technik ist eine Erfindung für starre Instrumente bekannt, bei der ein Knoten außerhalb des Körpers am einem Faßinstrument nahe der Spitze befestigt und mittels eines Knotenschiebers abgeschoben und zugezogen wird. Weiterhin sind Aufsteckvorrichtungen für biegsame Spiegelungsinstrumente bekannt, mittels derer Gummiringe über Gewebe appliziert werden. Entwicklungen zu Nahttechniken beinhalten zumeist aufwendige Einsaugvorrichtungen für das Gewebe und Röhren, in denen dann Nadeln vorgeschoben und der Faden durch das Gewebe gezogen wird. Es wird dagegen zur Vereinfachung vorgeschlagen, einen Aufsatz auf ein flexibles Spiegelungsinstrument zu verwenden, der eine Verdrehsicherung für eine, im Arbeitskanal des Instrumentes geführte Faßzange aufweist, der weiterhin ein Schlitz für das Aufnehmen des Faden beim Knotenschluß, einen Knotenschlitz genannt und eine weitere Schlitzbildung oder ähnliches mit einer integrierten Vorrichtung zum Abtrennen des Fadens, Fadenmesser genannt, aufweist.As the prior art, an invention for rigid instruments is known in which a Knot outside the body attached to a barrel instrument near the tip and is pushed and pulled by means of a knot pusher. Farther Attachments for flexible mirroring instruments are known, by means of whose rubber rings are applied over fabric. Developments in seam techniques mostly include complex suction devices for the tissue and tubes, in which needles are then advanced and the thread is pulled through the tissue. On the other hand, for the sake of simplicity, an essay on a flexible one is proposed Use a mirroring instrument that prevents rotation for one, in Working channel of the instrument guided grasping forceps, which continues to Slit for receiving the thread at the end of the knot, a knot slit called and another slot formation or the like with an integrated Device for cutting the thread, called thread knife.

Entsprechend muß die im Arbeitskanal geführt Faßzange zum Halten der Nadel oder zum Fassen des Fadens beim Knotenschluß eine Vorrichtung aufweisen, die paßgenau in die Verdrehsicherung des Aufsatzes eingreift. Die Vorrichtung ist im vorderen Bereich, beginnend hinter den Werkzeugskopf und nach hinten über eine bestimmte Strecke als Versteifung des ansonsten biegsamen Faßinstrumentes ausgeführt.Accordingly, the grasping forceps guided in the working channel must be used to hold the needle or have a device for grasping the thread when the knot is closed, the engages precisely in the anti-rotation lock of the attachment. The device is in front area, starting behind the tool head and backwards over a certain distance as stiffening of the otherwise flexible barrel instrument executed.
