Description

Kaltlichtquellen werden in der Medizin verwendet, um Licht in ein zu untersuchendes Körperareal zu bringen. Üblicherweise handelt es sich um Körperhöhlen, sodass die zu verwendende Lichtquelle sterilisierbar und ohne nennenswerte Temperaturentwicklung sein muß.Cold Light Sources are used in medicine to turn light into a to be examined body area bring to. Usually are body cavities, so the light source to be sterilized and without significant Temperature development must be.

Dies wird bisher durch externe Lichtquellen gewährleistet und das Licht wird durch sterilisierbare Glasfaserkabel in das zu untersuchende Areal über Instrumente eingeleitet.This is so far ensured by external light sources and the light is by sterilisable fiber optic cables into the area to be examined via instruments initiated.

Der Nachteil ist das Stören des sperrigen Glasfaserkabels am Instrument und bei der Handhabung allgemein. Die Glasfaserkabel unterliegen einem hohen Verschleiß durch die ständige Biegebeanspruchung und den Sterilisiervorgang mit entsprechendem Lichtverlust durch Faserbrüche. Die Einstellung der Lichtstärke ist nicht durch den sterilen Operateur sondern nur durch eine Hilfskraft an der externen Lichtquelle möglich.Of the Disadvantage is the disturbance the bulky fiber optic cable on the instrument and during handling generally. The fiber optic cables are subject to high wear the constant Bending stress and the sterilization process with appropriate Light loss due to fiber breakage. The setting of the light intensity is not by the sterile surgeon but only by a helper possible at the external light source.

Diese Probleme werden durch die im folgenden genannte direkte Kaltlichtquelle gelöst.These Problems are caused by the following direct cold light source solved.

Eine LED (2) mit entsprechender Lichtausbeute und Lichtfarbe‚ z. B. Luxeon K2 Emitter (Fa. Phillips) wird direkt in das erforderliche Instrument, im Beispiel (1) als Ersatz für den immer vorhandenen Kaltlichtkabeladapter (1a) fest ins Instrument eingebaut.An LED ( 2 ) with appropriate light output and light color, z. B. Luxeon K2 emitter (Phillips) is inserted directly into the required instrument, in the example ( 1 ) as a replacement for the always existing cold light cable adapter ( 1a ) built into the instrument.

LED dieser Produktfamilie sind mit mindestens 120° sterilisierbar, wie es dem normalen Kunststoffsterilisiervorgang gängiger Vacuum/Dampfsterilisatoren entspricht. Die Lichttfarbe entspricht Tageslicht. Die bei höherer Leistung erforderliche Kühlplatte der LED ist elektrisch neutral (3) mit dem Instrument an sich zu verbinden und dadurch für nichtstörende Wärmeabfuhr gesorgt. Die Baugröße erlaubt den Einbau in Lumina kleiner 8 mm.LEDs of this product family can be sterilized with at least 120 ° C, which corresponds to the normal plastic sterilization procedure of common vacuum / steam sterilizers. The light color corresponds to daylight. The cooling plate of the LED required for higher power is electrically neutral ( 3 ) to connect with the instrument itself and thereby ensured non-interference heat dissipation. The size allows installation in lumens smaller than 8 mm.

Ein direkt der LED optional aufzusetzende Optik (7) ist individuell an das Instrument anpassbar. Als Energiequelle (6) können eine Batterie oder Akku, die mindestens 350 mA liefert, dienen. Durch Ändern des Stromes ist die Lichtintensität über einen sterilisierbaren Regler (5) steuerbar. Diese Energiequelle ist mit einem leichten, flexiblen Kabel (4) beliebig zu positionieren, die Stromstärke direkt durch den Handhaber (Operateur) kabelgebunden am Regler (5) einstellbar.An optic that can be attached directly to the LED ( 7 ) is customizable to the instrument. As an energy source ( 6 ) can be a battery or rechargeable battery that supplies at least 350 mA serve. By changing the current, the light intensity is controlled by a sterilizable regulator ( 5 ) controllable. This power source is powered by a lightweight, flexible cable ( 4 ), the current directly by the operator (operator) wired to the controller ( 5 ) adjustable.

Durch diese Erfindung wird erreicht, dass ein verschleißintensives und manuell den Handhaber (Operateur) behinderndes Teil (Kaltlichtkabel) wegfällt.By This invention is achieved that a wear-intensive and manually the handler (surgeon) obstructing part (cold light cable) eliminated.

Es ist durch die direkte Lichterzeugung im Instrument oder im Patient weniger Leistungs und Lichtverlust zu vermerken. Die Bauteile, Instrumente können kleiner gebaut werden und sind besser zu handhaben.It is through direct light generation in the instrument or in the patient to note less power and light loss. The components, instruments can be smaller be built and are better to handle.

Die Nutzung mobiler Energiequellen (Batterie, Akku) ermöglichen den Einsatz unabhängig von einem zentralen Stromnetz und ist elektrisch sicherer für den Patienten.The Use of mobile energy sources (battery, rechargeable battery) the use independently from a central power grid and is electrically safer for the patient.

Die Steuerung der Lichtstärke durch Ändern der Stromstärke im sterilisierbaren Kabel ermöglicht die direkte Anpassung der Lichtstärke durch den Handhaber ohne fremde Hilfskräfte.The Control of the light intensity by changing the amperage in sterilizable cable allows the direct adjustment of the light intensity by the handler without outside helpers.
