Abstract

The means of assistance for use with a trocar ('T') has a low pressure chamber ('UK') in front of a movable sealing device 'KV'( trumpet,gate or ball valve) in the introduction direction. The chamber consists of a hollow body formed by two elastomer seals ('ED1' 'ED2') which have a connection ('AN') for a vacuum pipe ('S1'). The device also has a quick lock connection (SV) to the trocar such that several low pressure chambers, with various sizes of elastomer seals, can be used. The vacuum in the low pressure chamber is controlled, on the apparatus side, by a common connection of the gas supply pipe (S2) and the vacuum pipe to the insufflator.

Description

Zum Erreichen von Sicht im Bauchraum arbeitet die laparoskopische Technik mit einem Überdruck, dem sogenannten Pneumoperitoneum. Die unter der Operation zum Einführen der Instrumente verwendeten Hülsen, Trokare genannt, weisen deshalb Ventile (Trompeten- oder Klappenkonstruktionen) und Dichtungen auf. Beim Einführen und Entfernen der Instrumente entweicht das unter Druck stehende Gas. Mittels einem Insufflator wird durch Nachfüllen ein gewisser intraabdominaler Druck gehalten.It works to achieve vision in the abdomen laparoscopic technique with an overpressure, the so-called Pneumoperitoneum. The under the operation to introduce the Sleeves used in instruments, called trocars, therefore show Valves (trumpet or flap designs) and seals on. This escapes when the instruments are inserted and removed pressurized gas. By means of an insufflator Refilling held a certain intra-abdominal pressure.

Dabei ist es nachteilig, daß das entweichende Gas, zumeist CO2, auch in Richtung von Operateur und Assistenzpersonal geblasen wird. Dies wird allgemein spread-out genannt. Der spread-out enthält neben Wasserdampf auch Krankheitserreger, speziell Viren. So kann z. B. über die Schleimhäute der Augen eine Ansteckung des Personals erfolgen.It is disadvantageous that the escaping gas, mostly CO2, also blown in the direction of the surgeon and assistant staff becomes. This is commonly called spread out. The spread-out contains not only water vapor but also pathogens, specifically Viruses. So z. B. over the mucous membranes of the eyes Contagion of the staff take place.

Aufgabe der Erfindung ist, den spread-out zu verhindern.The object of the invention is to prevent the spread-out.

Dazu wird auf den Trokar eine Unterdruckkammer in Form eines Hohlkörpers aufgesetzt, der mit zwei Elastomerdichtungen und einem Anschluß für eine Unterdruckzuleitung versehen ist. Vorteilhaft kann der erforderliche Unterdruck auch über den Insufflator gesteuert werden und an den eingestellten intraabdominalen Druck angepaßt sein. Für die Operation sollen vorteilhaft alle Trokare bestückt sein, so daß die Unterdruckzuführung auch aus mehreren Leitungen bestehen kann, die schließlich alle in eine gemeinsame Zuleitung münden.For this purpose, a vacuum chamber in the form of a Hollow body placed with two elastomer seals and a connection for a vacuum supply line is provided. The required vacuum can also be advantageous via the Insufflator can be controlled and set at the intra-abdominal pressure. For the operation should advantageously all trocars are equipped so that the Vacuum supply can also consist of several lines, which ultimately all lead to a common supply line.

In Fig. 1 ist die Erfindung beispielhaft dargestellt. Es zeigtIn Fig. 1, the invention is shown as an example. It shows

Fig. 1 eine auf einen Trokar aufgesetzte Unterdruckkammer, über eine Schnellankupplung verbunden. Fig. 1 a vacuum chamber placed on a trocar, connected via a quick coupling.

Auf den Trokar T mit dem Verschlußelement KV ist die Unterdruckkammer UK aufgesetzt. Der Schnellschluß SV verbindet beide unter Andruck. Die Elastomerdichtungen ED1 und ED2 weisen beide den gleichen für die Instrumente dichtend anliegenden Durchmesser auf. An der Anschluß AN wird die Unterdruckzuleitung S1 angeschlossen. Die Schlauchleitungen S1 mit Unterdruck und S2 mit der Gaszufuhr können am Insufflator angeschlossen sein, um geräteseitig eine Anpassung beider Werte zu erreichen.On the trocar T with the closure element KV is the Vacuum chamber UK attached. The quick connect SV connects both under pressure. The elastomer seals ED1 and ED2 have both the same for the instruments sealing Diameter on. The vacuum supply line is connected to the connection AN S1 connected. The hose lines S1 with negative pressure and S2 with the gas supply can be connected to the insufflator to achieve an adjustment of both values on the device side.
