Abstract

A device is disclosed for drawing off gases and particles produced during surgical operations involving vaporisation and/or release of biological material. The device has an inlet aperture (10) to be directed at the operating area, a device (12) which communicates with the inlet aperture (10) and produces a vacuum, and a device (18, 19) for sanitizing the gases and particles drawn off from the operating area (16) in the form of a hot air section through which the gases and particles are led for a minimum time sufficient to ensure their sterilisation.

Description

Vorrichtung zum Absaugen von Gasen und Partikeln Device for suction of gases and particles
Die Erfindung betrifft eine Vorrichtung zum Absaugen von bei chirurgischen Eingriffen entstehenden Gasen und Par¬ tikeln, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a device for suctioning off gases and particles formed during surgical interventions, with the features of the preamble of claim 1.
Bei chirurgischen Eingriffen, bei denen biologisches Material vaporisiert wird, entstehen Gase und werden Partikel freigesetzt, die infektiös oder ansonsten unter hygienischen Gesichtspunkten in hohem Maße problematisch sein können.During surgery, in which biological material is vaporized, gases are generated and particles are released that can be infectious or otherwise highly problematic from a hygienic point of view.
Aus der DE 41 21 069 AI ist eine Vorrichtung bekannt, bei der die bei chirurgischen Eingriffen entstehenden Gase und Partikel abgesaugt und vor der Führung durch ein bakterien- und virenretentives Filter durch einen Flüssigkeitsbehälter geführt werden. Auch die DE 37 06 717 AI, die US 5 423 779 A und die US 4 963 134 offenba¬ ren die Verwendung von hygienischen Filtern zum Absaugen von bei chirurgischen Eingriffen entstehenden Gasen und Partikel.From DE 41 21 069 AI a device is known in which the gases and particles arising during surgical interventions are suctioned off and passed through a liquid container before being guided through a bacteria and virus-retentive filter. DE 37 06 717 A1, US Pat. No. 5,423,779 A and US Pat. No. 4,963,134 also disclose the use of hygienic filters for suctioning off gases and particles generated during surgical interventions.
Die genannte Vorrichtung löst das Problem nicht befrie¬ digend, da die Entsorgung der sich in dem Behälter befindlichen Flüssigkeit durchaus problematisch ist. Weiter ist die Funktionsfähigkeit des Filters bereits nach relativ kurzer Zeitdauer nicht mehr aureichend. Der Erfindung liegt die Aufgabe zugrunde, die vorbekann¬ te Vorrichtung zu verbessern.The device mentioned does not solve the problem satisfactorily, since the disposal of the liquid in the container is quite problematic. Furthermore, the functionality of the filter is no longer sufficient after a relatively short period of time. The object of the invention is to improve the previously known device.
Erfindungsgemäß wird diese Aufgabe dadurch die Merkmale des Anspruchs gelöst. Die Unteransprüche geben vorteil¬ hafte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by the features of the claim. The subclaims indicate advantageous embodiments of the invention.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert, in der die erfindungsgemäße Vorrichtung sche¬ matisch dargestellt ist.The invention is explained below with reference to a drawing in which the device according to the invention is shown schematically.
Die Vorrichtung weist eine Einrichtung 12, bei der es sich um einen handelsüblichen Staubsaugermotor handeln kann, auf, durch die das System mit Unterdruck beauf¬ schlagt wird. Der erzeugte Unterdruck bewirkt, daß die bei dem chirurgischen Eingriff unter Einsatz eines Lasers, eines HF-Gerätes oder eines Kauters 13 entste¬ henden Gase (insbesondere Rauchgase) und Partikel in eine auf das Operationsfeld 16 gerichtete, von dem Ope¬ rateur oder einem Assistenten gehaltende Ansaugöffnung 10 eintreten. Über einen Schlauch 11 werden die ange¬ saugten Gase und Partikel durch eine Heizeinrichtung 18, die mit Heizdrahtelementen versehen sein kann, geführt. Aus dieser treten die Gase und Partikel sodann in eine in dem dargestellten Ausführungsbeispiel als Rohr ausge¬ bildete Heißluftstrecke 19 ein, in der eine sehr hohe Temperatur, beispielsweise 500°C, entsteht, die eine Sterilisation der durch dieses geführten Gase und Parti¬ kel sicherstellt. Die an dem hinteren Ende der Vorrich¬ tung austretenden Gase und Partikel sind damit hygie¬ nisch unbedenklich.The device has a device 12, which can be a commercially available vacuum cleaner motor, through which the system is subjected to a vacuum. The negative pressure generated has the effect that the gases (in particular flue gases) and particles which arise during the surgical intervention using a laser, an HF device or a cautery 13 into particles directed towards the operating field 16 by the operator or an assistant enter the held suction opening 10. Via a hose 11, the sucked-in gases and particles are passed through a heating device 18, which can be provided with heating wire elements. From this, the gases and particles then enter a hot-air section 19, which is designed as a tube in the exemplary embodiment shown and in which a very high temperature, for example 500 ° C., arises, which ensures sterilization of the gases and particles passed through it . The gases and particles emerging at the rear end of the device are therefore hygienically harmless.
Um eine solche Sterilisation zuverlässig sicherzustel¬ len, ist hinter der Heizeinrichtung 18 ein Thermostat 24 vorgesehen, der erst bei Erreichen einer bestimmten Min¬ desttemperatur, beispielsweise 500°C, die Einrichtung 12 zum Erzeugen eines Unterdrucks einschaltet. Das Absaugen der Gase aus dem Bereich des Operationsfelds 16 über die Ansaugöffnung 10 erfolgt damit nur dann, wenn sicherge¬ stellt ist, daß die Heißluftstrecke 19 eine zur zuver¬ lässigen Sterilisation ausreichende Temperatur erreicht hat.In order to reliably ensure such sterilization, there is a thermostat 24 behind the heating device 18 provided that only switches on the device 12 for generating a negative pressure when a certain minimum temperature, for example 500 ° C., is reached. The gases are thus sucked out of the area of the operating field 16 via the suction opening 10 only when it is ensured that the hot air section 19 has reached a temperature sufficient for reliable sterilization.
Die Länge der Heißluftstrecke 19 ist dabei so gewählt, daß die Zeitdauer, über die die Gase und Partikel mit Hitze beauftragt werden, ausreichend ist, um eine zuver¬ lässige Sterilisation zu bewirken.The length of the hot air path 19 is chosen so that the period of time over which the gases and particles are subjected to heat is sufficient to effect reliable sterilization.
Bei dem dargestellten Ausführungsbeispiel ist weiter ein zwischen der Heißluftstrecke 19 und der Einrichtung 12 zum Erzeugen eines Unterdrucks angeordneter Katalysator 20 vorgesehen, der eine Nachverbrennung der sterilisier¬ ten Gase und Partikel bewirkt, bevor diese durch den Auslaß 25 in die Umgebung (oder einen Schornstein) abge¬ führt werden. Vor und hinter der Heißluftstrecke ist jeweils ein Filter (21 bzw. 23) vorgesehen. In the exemplary embodiment shown, a catalytic converter 20, which is arranged between the hot air section 19 and the device 12 for generating a negative pressure, is further provided, which causes the sterilized gases and particles to be combusted before they pass through the outlet 25 into the environment (or a chimney). be dissipated. A filter (21 and 23) is provided in front of and behind the hot air section.
