Description
Die Erfindung betrifft ein zahnärztliches Arbeits-Handstück mit einer Einrichtung zur Bildaufnahme, z. B. von Video-Sig nalen, bestehend aus einem Bildleiter und einem Lichtleiter.The invention relates to a dental work handpiece with a device for image acquisition, for. B. from Video-Sig nals, consisting of an image guide and a light guide.
Ein solches Arbeits-Handstück ist aus der DE-OS 22 08 902 bekannt. Dabei sind die beiden Leiter für das Bild und das Licht außenseitig an dem Handstück angebracht. Das hat verschiedene Nachteile zur Folge. So wird das Handstück durch die außen angebrachten Leiter und die angeschlossenen Schläuche voluminös und ist nur umständlich und unhygienisch zu handhaben. In den Schläuchen sind Zuleitungen zum Bildleiter und zum Lichtleiter unterzubringen, die z. B. als Glasfaserbündel ausgebildet sind. Diese sind ebenfalls voluminös und wenig biegsam, also bruchgefährdet, so daß die Handhabung weiter erschwert wird. Da bei dieser Ausbildung die Bildaufnahme-Einrichtung außerhalb angeordnet sein muß, verschlechtert sich durch die langen Übertragungs wege das Bild und das zugeführte Licht. Außerdem ist es erforderlich, zur Pflege, Reinigung und Desinfektion die Leiter und Schläuche abzunehmen, wenn man nicht die Übertragungsleistung verschlechtern will. Die Abnahme der Leiter und Schläuche ist aber wiederum umständlich.Such a work handpiece is from DE-OS 22 08 902 known. The two heads are for the picture and the light is attached to the outside of the handpiece. The has various disadvantages. This is how the handpiece becomes through the externally attached conductors and the connected ones Hoses are voluminous and are only cumbersome and unsanitary to handle. In the hoses are leads to Image guide and to accommodate the light guide, the z. B. are designed as a glass fiber bundle. These are also voluminous and not very flexible, therefore prone to breakage, see above that handling is further complicated. Because with this Training arranged the imaging device outside must be deteriorated by the long transmission move the image and the supplied light. Besides, is it is necessary for care, cleaning and disinfection to remove the conductors and hoses if you don't the transmission performance wants to deteriorate. The decrease the conductor and hoses are again cumbersome.
Die Erfindung, wie sie im Anspruch 1 gekennzeichnet ist, löst daher die Aufgabe, ein solches Handstück mit intra-oraler Bildübertragung zu schaffen, bei dem die Bildaufnahme-Einrichtung nicht stört und das in seinen Abmessungen, seiner Form und seiner Handhabung den üblichen zahnärztlichen Instrumenten entspricht.The invention as characterized in claim 1 is therefore solves the task of having such a handpiece to create intra-oral image transmission, in which the Image acquisition device does not bother and in his Dimensions, its shape and handling the usual corresponds to dental instruments.
Die Vorteile der Erfindung liegen bei dem die Bildaufnahme-
Einrichtung integriert enthaltenden Handstück neben
der Lösung der Aufgabe und der Beseitigung der erwähnten
Nachteile darin, eine direkte Einsicht in bislang schlecht
erreichbare Behandlungsräume, z. B. Wurzelkanäle zu ermög
lichen,
die Diagnose und die Kommunikation zwischen Zahnarzt
und Patient zu verbessern,
eine individuelle Anordnung auf der Zahnarzt- bzw. Helferin
nenseite zu ermöglichen,
einen minimalen Leistungsbedarf und erhöhte Bildgüte
durch verkürzte Leitungswege zu erbringen,
eine Integration als zusätzliches Instrument in den
üblichen Instrumentenhalterungen und -aufnahmen zu gewähr
leisten,
eine hygienische Pflege, Reinigung und Desinfektion
zu sichern und eine unabhängige Energieversorgung zu
ermöglichen und
die Dokumentation des Behandlungsvorgangs durchzuführen.The advantages of the invention lie in the handpiece which contains the image recording device integrated, in addition to the solution of the task and the elimination of the disadvantages mentioned, in direct insight into previously difficult to reach treatment rooms, e.g. B. to enable root canals,
improve diagnosis and communication between dentist and patient,
to allow an individual arrangement on the dentist's or helper's side,
to provide a minimal power requirement and increased image quality due to shortened cable routes,
ensure integration as an additional instrument in the usual instrument holders and holders,
to ensure hygienic care, cleaning and disinfection and to enable an independent energy supply and
carry out the documentation of the treatment process.
Ein optisches Zusatzinstrument, z. B. ein Spiegel, erübrigt sich. Ergonometrisches Arbeiten ist durch direkte Einsicht über indirekte Bilddarstellung möglich, ebenso ein hygieni sches Arbeiten durch vergrößerten Abstand zwischen dem Behandelnden und der Injektionsstelle.An additional optical instrument, e.g. B. a mirror, unnecessary yourself. Ergonometric work is through direct insight Possible via indirect image display, also a hygienic working thanks to the increased distance between the Treating and the injection site.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention result from the Subclaims.
