Abstract

The invention relates to an infrared coagulator which operates only in a narrow wavelength range of the infrared spectrum for treatment of vascular skin lesions.

Description

Die Erfindung geht aus von einem Strahlungskoagulator mit einer Strahlungs­ quelle, die einen hohen Infrarotanteil hat, mit einem in einem flexiblen Halterohr angebrachten Lichtleiter aus einem Bündel von Einzelfasern, und mit einer auf das Halterohr aufrastbaren hülsenförmigen Kappe, bei welcher wenigstens der mit der zu koagulierenden Gewebestelle in Kontakt kommende Bereich aus Silikonkautschuk besteht, nach Patent 37 23 227.The invention is based on a radiation coagulator with a radiation source that has a high infrared component, with one in a flexible Holding tube attached light guide from a bundle of individual fibers, and with a sleeve-shaped cap that can be snapped onto the holding tube which is at least the one in contact with the tissue site to be coagulated coming area consists of silicone rubber, according to patent 37 23 227.

Aus dieser Patentschrift ist ein Strahlungskoagulator bekannt, der eine breitbandige Infrarot-Lichtquelle benutzt. Es sind jedoch in der Dermatologie oder in der Zahnmedizin Anwendungsmöglichkeiten der Koagu­ lation bekannt, bei denen mit dem vorgenannten Gerät nicht das optimale Behandlungsergebnis erzielt wird, da für diese Fälle nur ein schmalbandi­ ger Teil des Infrarotbereiches benötigt wird.From this patent, a radiation coagulator is known, the one broadband infrared light source used. However, they are in the Dermatology or dentistry applications of the Koagu lation known in which with the aforementioned device is not the optimal Treatment result is achieved because in these cases only a narrow band ger part of the infrared range is required.

Die US-PS 42 33 493 beschreibt einen Infrarot-Koagulator mit einer Strahlungsquelle, die einen hohen Infrarotanteil aufweist. Außerdem ist ein in einem Halterohr gelagerter Lichtleiter vorgesehen, an dessen distalem Ende sich eine aufsteckbare hülsenförmige Kappe befindet, die in einem bestimmten Bereich mit der zu koagulierenden Gewebestelle in Berührung kommt.The US-PS 42 33 493 describes an infrared coagulator with a Radiation source that has a high infrared component. Besides, is a light guide mounted in a holding tube is provided, on the distal end is an attachable sleeve-shaped cap that in a certain area with the tissue site to be coagulated in Touch comes.

Weiterhin ist aus der DE-OS 31 13 869 ein Endoskop bekannt geworden, ein Bündel lichtleitender Fasern innerhalb eines flexiblen Rohres zu führen.Furthermore, an endoscope has become known from DE-OS 31 13 869, a To guide bundles of light-conducting fibers within a flexible tube.

Es ist Aufgabe der Erfindung, den bekannten Strahlungskoagulator so weiterzubilden, daß eine Behandlung mit Licht aus einem bevorzugten schmalen Wellenlängenbereich möglich wird.It is an object of the invention, the known radiation coagulator to further develop a treatment with light from a preferred narrow wavelength range is possible.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Hauptanspruches wiedergegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. This task is accomplished by the in the characterizing part of the main claim reproduced characteristics solved. Advantageous configurations the invention are specified in the subclaims.  

Der besondere Vorteil der Erfindung liegt darin, daß mittels eines schmalbandigen Infrarot-Koagulators beispielsweise vasculäre Hautverän­ derungen gezielt koaguliert werden können, während das umliegende Gewebe optimal geschont wird.The particular advantage of the invention is that by means of a narrow-band infrared coagulator, for example vascular skin changes changes can be targeted while the surrounding tissue is optimally protected.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:An embodiment is shown in the drawing and is in following described in more detail. Show it:

Fig. 1 einen Strahlungskoagulator mit flexiblem Halterohr, Fig. 1 is a Strahlungskoagulator with flexible holding tube,

Fig. 2 eine andere Ausführungsform mit festem Halterohr. Fig. 2 shows another embodiment with a fixed holding tube.

In der Fig. 1 ist ein Strahlungskoagulator dargestellt, der dem Aus­ führungsbeispiel in der Hauptanmeldung entspricht. Deshalb wird bezüg­ lich des konstruktiven Aufbaus des Koagulators auf die dortige Beschrei­ bung verwiesen.In Fig. 1, a radiation coagulator is shown, which corresponds to the exemplary embodiment from the main application. Therefore, with regard to the construction of the coagulator, reference is made to the description there.

Zusätzlich sind jedoch einige Merkmale geändert worden. Dies betrifft zum einen die Strahlungsquelle selbst. Hierfür wird eine Lichtquelle eingesetzt, die Infrarot-Licht aus dem erwünschten schmalbandigen Wellenlängenbereich emittiert. Es sind auch Lichtquellen einsetzbar, die in mehreren schmalen Wellenlängenbereichen des Infrarotspektrums emittieren. Falls davon nur ein Wellenlängenbereich zur Behandlung erwünscht ist, kann der Rest durch die nachfolgend beschriebenen Maß­ nahmen unterdrückt werden. Es ist auch denkbar, eine Umschaltvorrichtung zum wahlweisen Behandeln mit bestimmten Wellenlängen des Infrarotberei­ ches vorzusehen.In addition, some features have been changed. this concerns on the one hand, the radiation source itself. This becomes a light source used the infrared light from the desired narrow-band Wavelength range emitted. There are also light sources that can be used in several narrow wavelength ranges of the infrared spectrum emit. If there is only one wavelength range for treatment the rest can be desired by the measure described below were suppressed. A switching device is also conceivable for optional treatment with certain wavelengths of the infrared range ches to provide.

Unabhängig davon, ob eine breitbandige oder eine schmalbandige Strah­ lungsquelle 1 verwendet wird, sind normalerweise weitere Maßnahmen zur Selektion eines oder mehrerer Wellenlängenbereiche erforderlich. Es wird deshalb vorgeschlagen, den Reflektor 2 der Strahlungsquelle 1 so auszu­ statten, daß nur das Licht mit der erwünschten Wellenlänge reflektiert wird. Dies wird beispielsweise durch eine geeignete Beschichtung erreicht.Regardless of whether a broadband or a narrowband radiation source 1 is used, further measures for the selection of one or more wavelength ranges are normally required. It is therefore proposed to equip the reflector 2 of the radiation source 1 so that only the light with the desired wavelength is reflected. This is achieved, for example, by means of a suitable coating.

Weiterhin ist es vorgesehen, in den Strahlengang der Lichtquelle ein optisches Filter 3 einzufügen, das fest eingebaut oder auswechselbar im Lampengehäuse angeordnet sein kann.Furthermore, it is provided to insert an optical filter 3 into the beam path of the light source, which filter can be permanently installed or exchangeably arranged in the lamp housing.

Als zusätzliche Maßnahme kann die hülsenförmige Kappe 4 aus Silikonkaut­ schuk ebenfalls als Filter gestaltet sein. Dies wird beispielsweise durch eine besondere Einfärbung erzielt.As an additional measure, the sleeve-shaped cap 4 made of silicone rubber can also be designed as a filter. This is achieved, for example, through special coloring.
