Kamera für die DentalmedizinCamera for dental medicine

Die Erfindung betrifft eine Kamera für die Dentalmedizin gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a camera for dental medicine according to the preamble of claim 1.

In der Dentalmedizin werden Kameras verwendet, die einen Kopf aufweisen, welcher in den Mund des Patienten eingeführt werden kann, um Bildaufnahmen zu machen. Der Kopf enthält ein Objektiv, einen opto-elektronischen Bildwandler und eine Lichtquelle. Der Kopf ist über Kabel mit einem Monitor verbunden, der das aufgenommene Bild wiedergibt.In dentistry, cameras are used that have a head that can be inserted into the patient's mouth to take pictures. The head contains a lens, an opto-electronic image converter and a light source. The head is connected via cable to a monitor that displays the recorded image.

Bei der bekannten Kamera dient als Lichtquelle ein Projektor, dessen Licht über Lichtleitkabel zu dem Kopf mit dem Objektiv geführt wird. Das Lichtleitkabel und der Projektor machen die herkömmliche Kamera aufwendig. Der Energieverbrauch des Projektors ist relativ groß, damit ausreichend Licht erzeugt und 0 zu dem Objektiv geleitet werden kann. Das Lichtleitkabel verringert die Flexibilität der Leitungsverbindung des Kopfes.In the known camera, a projector serves as the light source, the light from which is guided to the head with the lens via a fiber optic cable. The fiber optic cable and the projector make the conventional camera complex. The energy consumption of the projector is relatively high so that sufficient light can be generated and guided to the lens. The fiber optic cable reduces the flexibility of the cable connection of the head.

Der Erfindung liegt die Aufgabe zugrunde, eine Kamera für die Dentalmedizin der eingangs genannten Gattung so zu verbessern, dass die Kamera preisgünstiger hergestellt werden kann, energiesparend ist und besser zu handhaben ist.The invention is based on the object of improving a camera for dental medicine of the type mentioned at the beginning so that the camera can be manufactured more cheaply, is energy-saving and is easier to handle.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Kamera mit den Merkmalen des Anspruchs 1.

Vorteilhafte Ausführung der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß werden als Lichtquelle für die Kamera Leucht-5 dioden verwendet, die in den Kopf eingesetzt sind. Dadurch ergibt sich ein Vorteil in den Herstellungskosten, da der auf-According to the invention, light-emitting diodes are used as the light source for the camera, which are inserted into the head. This results in an advantage in terms of production costs, since the

wendige Projektor und das aufwendige Lichtleitkabel entfallen können. Der Energieverbrauch der Leuchtdioden ist wesentlich geringer als der Energieverbrauch des herkömmlich verwendeten Projektors. Da kein Lichtleitkabel zu dem Kopf geführt werden muß, ist die Kabelverbindung des Kopfes flexibler, so dass der Kopf leichter und präziser geführt werden kann.The energy consumption of the LEDs is significantly lower than that of the conventionally used projector. Since no light-guide cable has to be fed to the head, the cable connection of the head is more flexible, so that the head can be guided more easily and precisely.

Vorzugsweise sind die Leuchtdioden kreisförmig um die in der Stirnfläche des Kopfes angebrachte Objektivlinse angeordnet. Dadurch ergibt sich eine optimale Ausleuchtung des Bildfeldes. 10Preferably, the LEDs are arranged in a circle around the objective lens mounted on the front surface of the head. This results in optimal illumination of the image field. 10

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.In the following, the invention is explained in more detail using an embodiment shown in the drawing.

Es zeigen
Figur 1 eine Seitenansicht der Kamera und Figur 2 eine distale Stirnansicht dieser Kamera.
Show it
Figure 1 is a side view of the camera and Figure 2 is a distal forehead view of this camera.

Die Kamera weist einen in der Zeichnung dargestellten Kopf auf, der über ein nicht dargestelltes flexibles Anschlußkabel mit einem Standgerät verbunden ist, welches unter anderem die Stromversorgung und einen Monitor aufweist.The camera has a head as shown in the drawing, which is connected via a flexible connection cable (not shown) to a stand-alone device which, among other things, has the power supply and a monitor.

Der Kopf weist ein langgestrecktes zylindrisches Gehäuse 10 auf. Der proximale hintere Gehäuseabschnitt, d.h. in der Figur 1 der rechte Abschnitt, ist als Griffbereich 12 ausgebildet. Der Griffbereich 12 ist mit zwei achsparallelen, abgeflachten, unter 90° zueinander angeordneten Flächen 14 versehen. Diese Flächen 14 dienen zur Orientierung des Kopfes in Rotationsrichtung, um dem Benutzer Bildoberseite und Bildunterseite der Kamera anzuzeigen. Weiter kann in einer der Flächen 14 ein Ausschalter angeordnet sein, der die Kamera automatisch ausschaltet, wenn der Kopf mit den Flächen 14 in einer entsprechenden Auflage des Standgeräts abgelegt wird.The head has an elongated cylindrical housing 10. The proximal rear housing section, i.e. the right section in Figure 1, is designed as a handle area 12. The handle area 12 is provided with two axially parallel, flattened surfaces 14 arranged at 90° to each other. These surfaces 14 serve to orient the head in the direction of rotation in order to show the user the top and bottom of the image of the camera. Furthermore, an off switch can be arranged in one of the surfaces 14, which automatically switches the camera off when the head with the surfaces 14 is placed in a corresponding support of the stand.

An dem in Figur 1 rechten proximalen Ende des Kopfes tritt koaxial das nicht dargestellte Anschlußkabel aus.The connecting cable (not shown) exits coaxially at the right proximal end of the head in Figure 1.

In der in Figur 1 linken distalen Hälfte des Kopfes ist das Gehäuse 10 zu einem Aufnahmebereich 16 im Durchmesser vergrößert. In diesem Aufnahmebereich 16 ist eine digitale elektronische Kamera aufgenommen, die einen opto-elektrischen Bildwandler mit zugehöriger Elektronik umfaßt. 5In the distal half of the head on the left in Figure 1, the housing 10 is enlarged in diameter to form a recording area 16. A digital electronic camera is accommodated in this recording area 16, which includes an opto-electrical image converter with associated electronics. 5

Die Objektivlinse 18 der elektronischen Kamera ist konzentrisch in der distalen Stirnfläche eines kreiszylindrischen Ansatzes 20 angeordnet, der am distalen Ende des Gehäuses 10 aufsteckbar ist. Auf einem die Objektivlinse 18 konzentrisch umschließenden Teilkreis sind in die Stirnfläche des Ansatzes 20 acht Leuchtdioden 22 eingesetzt. Die Lichtemissionsrichtung der Leuchtdioden 22 verläuft im Wesentlichen parallel zur Achse des Gehäuses 10 und zur Achse der Objektivlinse 18, so dass das Bildfeld der Objektivlinse 18 durch die Leuchtdioden 22 optimal ausgeleuchtet wird.The objective lens 18 of the electronic camera is arranged concentrically in the distal end face of a circular cylindrical attachment 20, which can be attached to the distal end of the housing 10. Eight light-emitting diodes 22 are inserted into the end face of the attachment 20 on a partial circle concentrically enclosing the objective lens 18. The light emission direction of the light-emitting diodes 22 runs essentially parallel to the axis of the housing 10 and to the axis of the objective lens 18, so that the image field of the objective lens 18 is optimally illuminated by the light-emitting diodes 22.

Die Stromversorgung für die Leuchtdioden 22 und die Elektronik der digitalen Kamera erfolgt durch das Anschlußkabel. Ebenso werden die elektrischen Bildsignale der Kamera über dieses 0 Anschlußkabel zu dem Standgerät und dem Monitor übertragen.The power supply for the LEDs 22 and the electronics of the digital camera is provided by the connection cable. The electrical image signals from the camera are also transmitted to the stand-alone device and the monitor via this connection cable.
