Abstract

The device has a sickle shaped cutting edge (1) with two conducting layers that are made of metal, and an insulated intermediate layer that is made of ceramic. The conducting layers are separated from the intermediate layer, where the cutting edge is operated as bipolar instrument with high frequency. A blade with additional separating effect is movable along the cutting edge.

Description

ZusammenfassungSummary

Die Erfindung betrifft eine Vorrichtung zum Schneiden von Gewebeteilen; wesentlicher Bestandteil ist eine sichelförmige, bipolar betriebene Schneide. The The invention relates to a device for cutting tissue parts; An essential component is a crescent-shaped, bipolar operated cutting edge.

Stand der TechnikState of technology

In der minimalinvasiven Chirurgie sind sichelförmige Schneidgeräte zum Ausschneiden von Gewebe bekannt. Die Schneide ist angeschliffen, wird, durch ein Trokar eingeführt, mit der Hand durch Ziehen und Drücken so bewegt, dass Teile aus dem Gewebe ausgeschnitten werden.In In minimally invasive surgery, crescent-shaped cutting cutters are used known by tissue. The cutting edge is ground, will, through a trocar introduced, by hand by pulling and pressing moved so that parts are cut out of the fabric.

Erfindunginvention

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, zur besseren Wirksamkeit die Schneidvorrichtung bipolar auszurüsten. Dazu wird das sichelförmige Ende aus zwei leitenden Schichten aufgebaut, z.B. aus Metall, die durch eine nichtleitende Schicht getrennt sind, z. B. aus Keramik. Beiden leitenden Schichten werden die Pole des Hochfrequenzgenerators zugeführt, der durch die Wirkung des Stroms das Schneiden erleichtert und die Schnittflächen durch Koagulation versiegelt.Of the present invention is based on the object, for the better Effectiveness equip the cutter bipolar. To becomes the crescent-shaped End composed of two conductive layers, e.g. made of metal, the separated by a nonconducting layer, e.g. B. ceramic. Both conductive layers become the poles of the high frequency generator supplied which facilitates cutting by the action of the stream and cuts through the cut surfaces Coagulation sealed.

Für die Ausführung der Schneide sind mehrere Ausführungen möglich, wobei die Schneide einseitig oder beidseitig angeschärft werden kann, je nach Ausführungsform der Erfindung. Prinzipiell ist dies für den Gebrauch unerheblich. Weitere mögliche Ausführungsformen sind in den Unteransprüchen beschrieben.For the execution of Cutting edge are several versions possible, wherein the cutting edge are sharpened on one or both sides can, depending on the embodiment the invention. In principle, this is irrelevant for the use. Other possible embodiments are in the subclaims described.

1 zeigt schematisch eine mögliche Ausführungsform der Erfindung. Dabei bezeichnet (1) die sichelförmige Schneide, (2) die Befestigung, (3) und (5) die leitenden Schichten und (4) die isolierende Trennschicht. Weitere Einzelheiten sind der übersicht wegen weggelassen. 1 shows schematically a possible embodiment of the invention. Where ( 1 ) the crescent-shaped cutting edge, ( 2 ) the attachment, ( 3 ) and ( 5 ) the conductive layers and ( 4 ) the insulating release layer. Further details are omitted for the sake of clarity.

2 zeigt eine mögliche Ausführungsform der Schneide, zweiseitig angeschliffen, 3 eine mögliche Ausführungsform, einseitig angeschliffen. 2 shows a possible embodiment of the cutting edge, ground on two sides, 3 a possible embodiment, ground on one side.

4 zeigt schematisch eine mögliche Erweiterung der Erfindung in der Draufsicht, mit (3) und (5) die leitenden Schichten und (4) die isolierende Trennschicht, durch Hinzufügen zweier rechteckiger Lamellen (6), im Beispiel angeschliffen, die seitlich an der sichelförmigen Schneideinrichtung entlang bewegt werden können und eine zusätzliche, sehr effektive Trennung des koagulierten Gewebes erleichtern. 4 schematically shows a possible extension of the invention in plan view, with 3 ) and ( 5 ) the conductive layers and ( 4 ) the insulating separating layer, by adding two rectangular lamellae ( 6 ) ground in the example, which can be moved laterally along the crescent-shaped cutter and facilitate additional, very effective separation of the coagulated tissue.
