Abstract

A device for prevention of steaming up or tarnishing of optics in endoscopy/laparoscopy by warming the objective lens e.g. by a heated wire, a UV-filter which itself heats up by the UV waves, or warmed air etc.

Description

Optische Geräte kommen in vielen Bereichen der Medizin zum Einsatz. Dabei werden flexible oder starre Endoskope verwendet. Mit diesen Geräten ist es möglich, Einblicke in Körperhöhlen zu erhalten. Dazu gehören der Magen-Darm-Trakt, die Bauchhöhle, Nasennebenhöhlen etc.Optical devices come in many areas of medicine. These are flexible or rigid endoscopes used. With these devices Is it possible, Insights into body cavities too receive. This includes the gastrointestinal tract, the abdominal cavity, Sinuses Etc.

Für eine scharfe Abbildung ist ein sauberes und klares Objektiv Voraussetzung.For A sharp picture is a clean and clear lens requirement.

In Körperhöhlen herrscht oftmals eine hohe Luftfeuchtigkeit. Dazu kommt eine Temperatur, die der Körpertemperatur entspricht. Dies kann zu Beschlagen der Optik führen. Die Sicht wird dadurch eingeschränkt. Eine Reinigung des Objektivs wird notwendig. Die Optik muß hierfür beispielsweise mittels eines Tuches trocken gewischt werden. Erst anschließend ist eine klare Sicht wieder hergestellt.In body cavities, there is often one high humidity. There is also a temperature, the body temperature equivalent. This can lead to fogging of the optics. The view is thereby limited. A Cleaning the lens becomes necessary. The optics must be for this example Wipe dry with a cloth. Only then is a clear view restored.

Wird das Objektiv erwärmt, findet keine Kondensation auf der Oberfläche statt. Ein Beschlagen ist nicht möglich. Die Reinigung aus diesem Grund entfällt. Eine Untersuchung oder Operation muß nicht unterbrochen werden. Die Untersuchungszeit ist kürzer, die Belastung für den Patienten geringer. Bei Operationen sinkt das Infektionsrisiko.If the lens is heated, finds no condensation on the surface instead. A fogging is not possible. The cleaning for this reason is eliminated. An investigation or Operation does not have to be interrupted become. The examination time is shorter, the burden on the patient lower. Surgery reduces the risk of infection.

Die Technik für die Erwärmung des Objektivs ist dabei vielfach vorstellbar. Ein Heizdraht könnte genauso dafür sorgen, wie ein UV-Filter, der sich durch die ultravioletten Strahlen erhitzt. Auch eine Erwärmung von innen mittels gewärmter Luft und andere Möglichkeiten sind vorstellbar.The technique for heating the lens is included often imaginable. A heating wire could just as well like a UV filter that heats up through the ultraviolet rays. Also, a warming from the inside by means of warmed Air and other possibilities are conceivable.
