Description

Hintergrund der ErfindungBackground of the invention

(a) Bereich der Erfindung(a) Field of the invention

Die Erfindung betrifft ein Lichtleitrohr aus Verbundmaterial, das zur Übertragung von Lichtstrahlen geeignet ist.The invention relates to a light pipe made of composite material, which is suitable for the transmission of light beams.

(b) Beschreibung des derzeitigen Standes der Technik(b) Description of the current state of the art

Arbeiten werden häufig durch nicht ausreichende Objektbeleuchtung erschwert.Working is often complicated by insufficient lighting of the object.

Wenn sich z. B. während eines zahnärztlichen Eingriffs Blut und Speichel in der Mundhöhle sammeln, kommt es leicht zu einer Einschränkung der Sicht, die den weiteren Verlauf der Behandlung negativ beeinflußt. Die Flüssigkeit muss dann mit Hilfe von Absaugeinrichtungen durch röhrenartige Gebilde abgesaugt werden.If z. B. accumulate blood and saliva in the oral cavity during a dental procedure, it is easy to limit the view, which adversely affects the further course of treatment. The liquid must then be sucked by means of suction through tubular structures.

Da der Pateint den Mund nur bis zu einem gewissen Grad öffnen kann, bleibt dem Zahnarzt häufig keine andere Wahl, als zu versuchen durch Drehen des Kopfs des Patienten die Beleuchtungsverhältnisse zu verbessern.Since the godfather can only open his mouth to a certain degree, the dentist often has no choice but to try to improve the lighting conditions by turning the patient's head.

Auch bei einigen anderen medizinischen Prozeduren, wie z. B. Spiegelungen des Körperinnern, Magenspiegelungen, Darmspiegelungen etc. treten ähnliche Probleme auf, die dann durch eine außen an der Sonde angebrachte Beleuchtungseinheit gelöst werden müssen.Also in some other medical procedures, such. B. reflections of the inside of the body, gastroscopy, colonoscopy, etc., similar problems occur, which must then be solved by an externally attached to the probe lighting unit.

Dies führt zu einer häufig nur schwer akzeptablen Verdickung der Sonde und wegen des vergrößerten Sondenkopfs zu Manovrierschwierigkeiten.This leads to a thickening of the probe, which is often difficult to accept, and to maneuvering difficulties due to the enlarged probe head.

Zusammenfassung der ErfindungSummary of the invention

Ziel der Erfindung ist eine rohrartige Struktur aus einem Kunststoffmaterial und Kunststofffasern, die Licht weiterleiten kann, die sich dadurch auszeichnet, dass wenn Licht an einem Ende eingeleitet wird, dieses am anderen Ende austritt, wobei am Austrittsende keine weitere Lichtquelle nötig ist, die das Gewicht erhöhen und das Manövrieren erschweren würde.The aim of the invention is a tubular structure made of a plastic material and plastic fibers, which can pass light, which is characterized in that when light is introduced at one end, it exits at the other end, wherein at the outlet end, no further light source is required, the weight increase and make maneuvering more difficult.

Ihre Konstruktion soll so einfach sein, dass sie an allerlei Arten von medizinischen Eingriffen angepasst werden kann.Their design should be so simple that it can be adapted to all kinds of medical procedures.

Detaillierte Beschreibung der bevorzugten AusführungDetailed description of the preferred embodiment

1 bis 4 zeigen ein erfindungsgemäßes Lichtleitrohr aus Verbundmaterial (30), das eine Anzahl Lichtwellenleiter (10) und Kunststoffmaterial (20) enthält. 1 to 4 show a light pipe according to the invention made of composite material ( 30 ) containing a number of optical fibers ( 10 ) and plastic material ( 20 ) contains.

Jeder einzelne Lichtwellenleiter (10) hat ein Lichtaustrittsende (11) und ein Lichteintrittsende (12), wobei ein am Lichteintrittsende (12) eingeleiteter Lichtstrahl am Lichtaustrittsende (11) wieder austritt.Each individual optical fiber ( 10 ) has a light exit end ( 11 ) and a light entry end ( 12 ), one at the light entry end ( 12 ) introduced light beam at the light exit end ( 11 ) exit again.

Das Kunststoffmaterial (20) umgibt dabei die Lichtwellenleiter (10), um sie in ihrer Lage zueinander zu fixieren und um die Rohrstruktur auszubilden. Die Lichtaustrittsenden (11) der einzelnen Lichtwellenleiter (10) werden dabei zu einem rohrartigen Lichtaustritt (31) zusammengefasst, wobei die Lichtaustrittsenden (11) in die Rohrwandung eingebettet sind. Die Lichteintrittsenden (12) werden analog dazu zu einem ebenfalls rohrartigen Lichteintritt (32) zusammengefasst.The plastic material ( 20 ) surrounds the optical waveguides ( 10 ) in order to fix them in relation to each other and to form the tube structure. The light emission ends ( 11 ) of the individual optical fibers ( 10 ) become a tube-like light exit ( 31 ), wherein the light exit ends ( 11 ) are embedded in the pipe wall. The light entry ends ( 12 ) are analogous to a likewise tube-like light entrance ( 32 ) summarized.

Die Lichtwellenleiter (10) sind in das Kunststoffmaterial (20) eingebettet, so dass Lichtstrahlen, die am Lichteintrittsende (12) in einen Lichtwellenleiter (10) eintreten von diesem weitergeleitet werden, bis sie am Lichtaustrittsende (11) wieder austreten.The optical fibers ( 10 ) are in the plastic material ( 20 ), so that light rays at the light entry end ( 12 ) in an optical waveguide ( 10 ) are forwarded by this until they at the light exit end ( 11 ) emerge again.

Die vorliegende Erfindung kann nicht nur als gewöhnliche Rohrstruktur benutzt werden, sondern es kann auch am Lichteintritt (32) eine Lichtquelle oder eine Bildaufnahmevorrichtung angesetzt werden, um entweder den Bereich vor dem Lichtaustritt (31) zu beleuchten oder zu betrachten. Das Kunststoffmaterial (20) kann dabei an die verschiedensten Einsatzfälle wie hohe Temperaturen oder aggressive Umgebung angepasst werden. Es ist daher ein Einsatz sowohl im Ingenieurwesen als auch in der Medizin möglich.The present invention can not only be used as an ordinary tube structure, but it can also be used at the light entrance ( 32 ) a light source or an image pickup device can be used to either the area before the light exit ( 31 ) to illuminate or to look at. The plastic material ( 20 ) can be adapted to a wide variety of applications such as high temperatures or aggressive environments. It is therefore possible to use both in engineering and in medicine.

Da es beim Einsatz der Erfindung nicht nötig ist eine äußere Lichtquelle anzubauen, wird das damit verbundene Schwererwerden des Endes vermieden und die Bedienung erleichtert. Bei invasiver medizinischer Behandlung braucht nur eine kleine Öffnung in den Körper des Patienten geschnitten werden, was anschließend die Wundheilung erleichtert.Since it is not necessary to use an external light source when using the invention, the associated heaviness of the end is avoided and the operation is facilitated. In invasive medical treatment, only a small opening in the body of the patient needs to be cut, which then facilitates wound healing.

2, 3 und 5 zeigen, dass es möglich ist die Lichteintrittsenden (12) alle an einer Stelle zum Lichteintritt (32) zusammenzufügen, was es erleichtert alle Lichtwellenleiter (10) mit einer Lichtquelle zu speisen. Ein einschlägiges Ausführungsbeispiel ist in 6 dargestellt. Dort ist die erfindungsgemäße Rohrstruktur aus Lichtwellenleitern an einem Handgriff H befestigt, in dem außerdem eine Lichtquelle L und eine Lichtübertragungseinheit T untergebracht sind. Das von L ausgesandte Licht wird am einen Ende von T aufgenommen und am anderen an den Lichteintritt (32) weitergegeben. Des weiteren kann in dem in 2 und 5 mit S markierten, nicht mit Lichtwellenleitern (10) bestückten Bereich des Kunststoffmaterials (20) eine mechanische Verstärkung durch Gewebeeinlagen oder mit Silizium- oder Zirkonmaterial vorgenommen werden. 2 . 3 and 5 show that it is possible the light entry ends ( 12 ) all in one place for light entry ( 32 ), which facilitates all optical fibers ( 10 ) with a light source. A relevant embodiment is in 6 shown. There, the pipe structure of optical waveguides according to the invention is attached to a handle H, in which also a light source L and a light transmission unit T are housed. The light emitted by L is received at one end of T and at the other at the light entrance ( 32 ). Furthermore, in the in 2 and 5 marked with S, not with optical fibers ( 10 ) equipped area of the plastic material ( 20 ) a mechanical reinforcement by fabric inserts or with silicon or zirconium material can be made.

Das Zusammenfassen der Lichteintrittsenden (12) an einem Ort ermöglicht es eine ausreichende Lichtzufuhr mit nur wenigen Leuchtelementen L zu erzielen und erlaubt damit eine Energieeinsparung. Bei geeigneter Ausführung der Lichtquelle L kann auf die Lichtübertragungseinheit T verzichtet werden.The summarization of the light entry ends ( 12 ) in one place makes it possible to achieve a sufficient supply of light with only a few light elements L and thus allows energy savings. In a suitable embodiment of the light source L can be dispensed with the light transmission unit T.

Bei der in 7 und 8 gezeigten Ausführung sind die Lichteintrittsenden (12) um den Lichteintritt (32) herum verteilt angeordnet. Dies erlaubt es, noch mehr Leuchtelemente einzusetzen, wobei jedes Lichteintrittsende (12) mit Licht versorgt wird. Ein Beispiel dafür zeigt 9. Jedes Leuchtelement kann selbstverständlich mehr als ein Lichteintrittsende (12) beleuchten.At the in 7 and 8th In the embodiment shown, the light entry ends ( 12 ) around the light entry ( 32 ) arranged around it. This makes it possible to use even more lighting elements, each light entry end ( 12 ) is supplied with light. An example of this shows 9 , Of course, each lighting element can have more than one light entry end ( 12 ) illuminate.

Der Lichtwellenleiter (10) kann außerdem entweder eine optische Mikrolichtwellenleitfaser oder jede andere Lichtwellenleitfaser sein. Ebenso ist ihre Anordnung, ob parallel oder über Kreuz, um die Festigkeit zu erhöhen beliebig.The optical fiber ( 10 ) may also be either a microlight optical fiber or any other optical fiber. Likewise, their arrangement, whether parallel or crosswise, to increase the strength is arbitrary.

Das Kunststoffmaterial kann ein Duroplast oder thermoplastisches Material, wie z. B. Kunstharz, Polyester, Phenoplast, Acrylkunststoff, Ethylene oder anderes sein. Es kann zwischen 3% und 70% des Gesamtvolumens betragen, der Lichtwellenleiteranteil am Volumen kann also zwischen 30% und 97% liegen.The plastic material may be a thermoset or thermoplastic material, such. As synthetic resin, polyester, phenolic, acrylic plastic, ethylene or other. It can be between 3% and 70% of the total volume, so the fiber fraction of the volume can be between 30% and 97%.
