Die Beleuchtungseinrichtung ist über eine elektrische Leitungsverbindung mit einer Stromversorgung lösbar verbunden.In German Utility Model Application DE 20 2004 000 159.4 a retractor, consisting of wound hook blade and retractor handle, with white or color-adjustable LED lighting disclosed, wherein the lighting device, consisting of LED, socket with holder, optical lenses, depending on required focusing, also called light-conducting, application-specific Additional optics, reflector, instrument housing with holding frame and socket with electrical connections / contacting, at the end of the retractor handle - close the wound hook sheet - so is positioned that the Intervention is always illuminated. The lighting device is over an electrical line connection to a power supply releasably connected.
Die Arbeitsweise der Instrumente mit der Lichtleiter-Technologie und externer Lichtquelle weisen folgende Nachteile auf
- 1. Handhabung des Wundhakens mit angekoppeltem Lichtleiter
- 2. Steif- und Starrheit der Lichtleiter-Applikation in Bezug auf Biegsamkeit
- 3. Auslegung des Lichtleiter-Querschnitts für die benötigte Lichtmenge
- 4. Lichtverluste durch Leitungslängen mit Krümmungen, Steckverbinder und an den Ein- und Austrittstellen
- 5. Kühlungsaufwand bei der Lichterzeugung durch Wärmestrahler.
- 1. Handling the retractor with coupled light guide
- 2. Rigidity and rigidity of the optical fiber application in terms of flexibility
- 3. Design of the optical fiber cross section for the required amount of light
- 4. Light losses due to cable lengths with bends, connectors and at the entry and exit points
- 5. Cooling effort in the light generation by radiant heater.
Der Erfindung liegt daher die Aufgabe zugrunde, die in der Handhabung des Wundhakens störende, feste oder lösbare, Lichtleiter-Applikation mit externer Lichtquelle zu ersetzen.Of the Invention is therefore the object of the handling disturbing the retractor, fixed or detachable, Replace optical fiber application with external light source.
Diese Aufgabe wird gemäß Gebrauchsmusteranmeldung DE 20 2004 000 159.4 dadurch gelöst, daß mit einfachen und ggfs. vorhandenen Mitteln die energiesparenden und wartungsfreundlichen Halbleiter-Leuchtdioden (LED) lokal im Instrument eingesetzt werden.This object is achieved according to utility model application DE 20 2004 000 159.4, characterized that with simple and possibly existing means the energy-saving and maintenance-friendly semiconductor light-emitting diodes (LED) are used locally in the instrument.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Eingriffsstelle des Wundhakens beleuchtet ist, ohne dabei an externe Versorgungen durch Licht, wie lösbare oder feste Lichtleiter-Verbindungen, gebunden zu sein.The particular advantages of the invention are that the Engagement point of the retractor is illuminated, without losing to external Supplies of light, such as solvable or solid fiber optic connections to be bonded.
Als nachteilig erweist sich weiterhin, daß die in dem Wundhaken fest montierte, nicht lösbare LED-Beleuchtungseinrichtung ungeschützt dem Sterilisationsprozeß ausgesetzt ist.When Another disadvantage is that the stuck in the retractor mounted, non-detachable LED lighting device unprotected exposed to the sterilization process is.
Der Erfindung liegt daher die Aufgabe zugrunde, Möglichkeiten zu schaffen, die Halbleiter-Bauelemente thermisch zu sichern.Of the Invention is therefore based on the object to create opportunities that Thermally secure semiconductor devices.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, die LED-Beleuchtungeinrichtung, mindestens jedoch die Halbleiter-Bauelemente, in eine ummantelnde thermische Hülle einzubetten.These Task is inventively characterized solved, the LED lighting device, but at least the semiconductor devices, in a jacketing thermal envelope embed.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Instrument ohne Umbau- oder Zerlegemaßnahmen gewartet und gereinigt werden kann.The particular advantages of the invention are that this Instrument serviced and cleaned without modification or disassembly can be.
