Konverter für stark gebogene Faßzange ZusammenfassungConverter for strongly curved grasping forceps Summary

Die Erfindung betrifft einen Konverter für eine stark gebogene Faßzange für die Anwendung in der Minimalinvasiven Chirurgie.The invention relates to a converter for a strongly curved grasping forceps for use in minimally invasive surgery.

Stand der TechnikState of the art

Konverter sind Einsatzteile für Trokare zum Einführen von Instrumenten in den Operationsraum in der Minimalinvasiven Chirurgie. Vielfache Verwendung finden dabei auch stark gebogene Faßzangen. Problem dabei ist die Einführung dieser stark gebogenen Faßzangen durch einen entsprechenden Konverter und die sichere Abdichtung gegen das Austreten des für die Auffüllung des Operationsraumes benutzten Gases. Verwendete Konverter mitConverters are inserts for trocars for introducing instruments into the operating room in minimally invasive surgery. Strongly curved grasping forceps are also often used. The problem here is the introduction of these strongly curved grasping forceps through a corresponding converter and the secure sealing against the escape of the gas used to fill the operating room. Converters used with

entsprechend großem Durchmesser für die gebogene Faßzange werden mit sternförmig eingeschnittenen Dichtungen versehen, die weder eine einwandfreie Dichtung noch eine saubere Führung der Faßzange während des Gebrauchs gewährleisten. 25with a correspondingly large diameter for the curved grasping forceps are provided with star-shaped seals that neither ensure a perfect seal nor clean guidance of the grasping forceps during use. 25

Erfindunginvention

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, einen Konverter so umzugestalten, daß sowohl die Einführung der stark gebogenen Faßzange als auch deren sichere Führung während des Gebrauchs gewährleistet wird. Eine weitere Ausgestaltung der Erfindung betrifft die die Ausführung einer entsprechenden Dichtung.The present invention is based on the task of redesigning a converter in such a way that both the insertion of the strongly curved grasping forceps and their safe guidance during use are ensured. A further embodiment of the invention relates to the design of a corresponding seal.

Dazu wird der Konverter an seinem Ende mit einem Teil abgeschlossen, das eine schlüssellochförmige Öffnung besitzt, hergestellt aus zwei Bohrungen mit größerem und kleinerem Durchmesser, verbunden durch einen Schlitz. Die größere Bohrung entspricht dem Durchmesser des Schafts der Faßzange, die damit leicht durch den Schlitz und die andere Bohrung eingeführtFor this purpose, the converter is closed at its end with a part that has a keyhole-shaped opening, made of two holes with a larger and smaller diameter, connected by a slot. The larger hole corresponds to the diameter of the shaft of the grasping forceps, which can then be easily inserted through the slot and the other hole

,werden kann. Die Faßzange wird damit während des Gebrauchs >sicher geführt. Die kleinere Bohrung bietet zusätzlich die Möglichkeit, ein weiteres Instrument einzuführen.,can be used. The grasping forceps are thus >safely guided during use. The smaller hole also offers the possibility of inserting another instrument.

Die weitere Ausgestaltug der Erfindung betrifft die zugehörige Dichtung zur Abdichtung der schlussellochformigen Öffnung. Entsprechend ihrem Verwendungszweck besteht sie aus einer Scheibe mit einem Loch an der Stelle der größeren Bohrung und ein erweiterbares Stichloch an der Stelle der kleineren BohrungThe further embodiment of the invention relates to the associated seal for sealing the keyhole-shaped opening. According to its intended use, it consists of a disc with a hole at the location of the larger hole and an expandable tap hole at the location of the smaller hole

10, des Schlüssellochs. Damit ist eine zuverlässige Abdichtung der Öffnungen gewährleistet. Um die Dichtung zu den Bohrungen richtig orientieren zu können, wird sie aus transparentem Material hergestellt.10, of the keyhole. This ensures reliable sealing of the openings. In order to be able to orient the seal correctly to the holes, it is made of transparent material.

Fig. 1 zeigt schematisch eine mögliche Ausführungsform der Erfindung. Dabei bezeichnet (1) den oberen Teil des Konverters mit der schlussellochformigen Öffnung (2) zur Einführung der stark gebogenen Faßzange. Fig. 2 zeigt schematisch eine mögliche Ausführungsform der transparenten Dichtung.Fig. 1 shows a possible embodiment of the invention schematically.
