Intraoral eines Patientenmundes plazierbarer Sensor zur Erstellung von Zahn-/Kieferaufnahmen eines PatientenSensor that can be placed intraorally in a patient’s mouth to create dental/jaw images of a patient
Die Erfindung betrifft einen intraoral eines Patientenmundes plazierbaren Sensor zur Erstellung von Zahn-/ Kieferaufnahmen eines Patienten mit einem schmalen, in der Regel rechteckförmigen Gehäuse zur Aufnahme eines BiIdsensors und einer diesem zugeordneten Steuerplatine, an der diverse Leitungen eines Anschlußkabels angeschlossen sind, welches mit seinem freien Ende mit einer Bildverarbeitungseinheit verbindbar ist.The invention relates to a sensor that can be placed intraorally in a patient's mouth for creating dental/jaw images of a patient, with a narrow, usually rectangular housing for accommodating an image sensor and a control board associated with it, to which various lines of a connecting cable are connected, which can be connected with its free end to an image processing unit.
Solche Intraoralsensoren sind beispielsweise aus den Druckschriften mit dem Titel "VISUALIX the new way to take dental X-rays" der Firma 'Philips Medical Systems' und "SENS-A-RAY a revolution in dental radiography" der Firma 'Regam Medical Systems AB1 bekannt. Das Anschlußkabel tritt bei diesen bekannten Ausführungen entweder stirnseitig der schmäleren Seitenwandung des Gehäuses oder rechtwinkelig dazu an der Rückwand des Gehäuses aus.Such intraoral sensors are known, for example, from the publications entitled "VISUALIX the new way to take dental X-rays" by Philips Medical Systems and "SENS-A-RAY a revolution in dental radiography" by Regam Medical Systems AB 1. In these known versions, the connecting cable either exits from the front of the narrower side wall of the housing or at a right angle to it on the rear wall of the housing.
Beide Ausführungsformen haben hinsichtlich der Positonierung des Sensors in der Mundhöhle des Patienten Nachteile, insbesondere wenn man Aufnahmen im Frontzahnbereich oder im hinteren Molarbereich erstellen möchte. Zum einen ist die Kabelführung für den Patienten unangenehm bzw. störend, wenn er den Sensor am aufzunehmenden Zahn positionieren will; zum anderen kann es leicht vorkommen, daß das aus dem Patientenmund herauszuführende Anschlußkabel unzulässig geknickt wird.Both versions have disadvantages with regard to the positioning of the sensor in the patient's oral cavity, especially if you want to take pictures in the front teeth area or in the back molar area. On the one hand, the cable routing is uncomfortable or annoying for the patient when he wants to position the sensor on the tooth to be recorded; on the other hand, it can easily happen that the connecting cable leading out of the patient's mouth is kinked in an unacceptable way.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, demgegenüber eine Verbesserung zu schaffen.The invention defined in claim 1 is based on the object of creating an improvement thereto.
Dadurch, daß der Kabelaustritt des Anschlußkabels schräg zur Längsebene des Gehäuses bzw. zur Sensorebene in dem angegebenen Winkelbereich, der vorzugsweise bei 40 bis liegt, erfolgt, wird für nahezu alle Zahnaufnahmen eine optimale Positonierung des Sensors erzielt. Vorteilhafterweise ist an der Kabelaustrittsstelle das Gehäuse mit einer konvexen Wölbung versehen, die durch eine am Gehäuse angeformte Kappe gebildet sein kann. Damit lassen sich sehr gut die Anschlußleitungen unterbringen, ohne daß das Gehäuse insgesamt baulich vergrößert zu werden braucht. Die Wölbung dient gleichzeitig als Positionierhilfe für den Patienten beim Anlegen des Sensors an den aufzunehmenden Zahn. Besonders vorteilhaft ist es hierzu, wenn die Wölbung mit einer konkaven Fingermulde versehen ist.Because the cable exits at an angle to the longitudinal plane of the housing or the sensor plane in the specified angle range, which is preferably between 40 and 60, the sensor is optimally positioned for almost all tooth images. The housing is advantageously provided with a convex curvature at the cable exit point, which can be formed by a cap molded onto the housing. This makes it very easy to accommodate the connecting cables without the overall housing having to be structurally enlarged. The curvature also serves as a positioning aid for the patient when placing the sensor on the tooth to be imaged. It is particularly advantageous if the curvature is provided with a concave finger recess.
Weitere Vorteile ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispieles.Further advantages will become apparent from the following description of an embodiment.
Die Figur zeigt in einer Seitenansicht und teilweise im Schnitt eine Ausführung des erfindungsgemäßen Intraoralsensors. In einem in der Draufsicht etwa rechteckförmigen Gehäuse 1 ist ein in der Figur nicht dargestellter Bildsensor (CCD-Sensor) untergebracht, der in geeigneter Weise mit einer Steuerplatine 2 verbunden ist. An der Steuerplatine 2, die diverse elektronische, nicht näher bezeichnete Bauteile enthält, enden Leitungen 3, die in einem mit 4 bezeichneten Anschlußkabel aus dem Gehäuse 1 herausgeführt und, wie eingangs dargelegt, zu einer (nicht dargestellten) Bildverarbeitungseinheit führen.The figure shows a side view and partially in section of an embodiment of the intraoral sensor according to the invention. In a housing 1 that is approximately rectangular in plan view, an image sensor (CCD sensor) not shown in the figure is housed, which is connected in a suitable manner to a control board 2. Lines 3 end on the control board 2, which contains various electronic components not specified in more detail. These are led out of the housing 1 in a connecting cable designated 4 and, as explained at the beginning, lead to an image processing unit (not shown).

Der Kabelaustritt des Anschlußkabels 4 erfolgt an der Rückwand des Gehäuses 1 unter einem Winkel oC > der zwischen 30 und 60° zur Längsebene des Gehäuses liegt. Wie aus der Darstellung hervorgeht, enthält das Gehäuse 1 im Bereich des Kabelaustritts eine konvexe Wölbung, die durch eine an das Gehäuse angeformte Kappe 5 gebildet ist. Die Kappe 5 ist an der mit 6 bezeichneten Stelle quergeteilt. Im unteren Kappenteil 5a ist das Anschlußkabel 4 zugentlastend gefaßt, wobei das Anschlußkabel und die Leitungsenden wasserdicht mit der Kappe verklebt sind. Beide Kappenteile werden bei der Endmontage ebenfalls wasserdicht miteinander verbunden.The cable exit of the connecting cable 4 is at the rear wall of the housing 1 at an angle oC > which is between 30 and 60° to the longitudinal plane of the housing. As can be seen from the illustration, the housing 1 contains a convex curvature in the area of the cable exit, which is formed by a cap 5 molded onto the housing. The cap 5 is divided transversely at the point marked 6. The connecting cable 4 is held in the lower cap part 5a in a strain-relieving manner, with the connecting cable and the cable ends being glued to the cap in a watertight manner. Both cap parts are also connected to one another in a watertight manner during final assembly.
Obgleich die konvexe Wölbung bereits für sich eine gute Positionierhilfe für den Patienten beim Anlegen des Sensors an den aufzunehmenden Zahn ist, kann es doch vorteilhaft sein, zweckmäßigerweise im oberen Kappenteil 5b eine konkav ausgebildete Fingermulde 7, wie sie in der Figur gestrichelt eingezeichnet ist, vorzusehen. 20Although the convex curvature is already a good positioning aid for the patient when placing the sensor on the tooth to be recorded, it can be advantageous to provide a concave finger recess 7 in the upper cap part 5b, as shown in dashed lines in the figure. 20
