Abstract
Description
Die Erfindung betrifft eine endoskopische Optik mit einer elektrischen Schalteinrichtung.The The invention relates to an endoscopic optic with an electrical Switching device.
Solche Optiken werden in der Chirurgie und dort vor allem in der Laparoskopie verwendet. Die Schalteinrichtung ist am Hauptkörper der Optik angeordnet, an dem ohnehin zu Zwecken der Handhabung angegriffen wird und wo die Schalteinrichtung leicht mit der haltenden Hand betätigt werden kann. Die Schalteinrichtung kann allen möglichen Zwecken dienen und kann Funktionen des Endoskopes oder auch Funktionen anderer Geräte steuern. Der Operateur muss dazu die Hand nicht von der Optik nehmen.Such Optics are used in surgery and there especially in laparoscopy used. The switching device is arranged on the main body of the optics, which is attacked anyway for purposes of handling and where the switching device can be easily operated with the holding hand can. The switching device can serve all sorts of purposes and can control functions of the endoscope or functions of other devices. The surgeon does not have to take his hand off the optics.
Es ist bekannt, auf solchen Optiken einen drehbaren Ring zu lagern, der insbesondere dazu dienen kann, über magnetischen Durchgriff durch die Gehäusewand des Hauptkörpers eine innenliegende Drehsteuerung mitzunehmen, die z. B. zur Fokusverstellung dient oder die bei einem Videoendoskop mit schrä ger Blickrichtung den Kamerasensor gegenüber dem Objektiv dreht. Eine solche Optik wird so gehandhabt, dass sie mit der Hand am Ring gehalten wird, der dadurch drehfest gehalten ist. Zur Blickrichtungsverstellung wird die Optik relativ zum Ring gedreht.It is known to store on such optics a rotatable ring, which can serve in particular, via magnetic penetration through the housing wall of the main body to take an internal rotation control, the z. B. for focus adjustment serves or in a video endoscope with schrä ger viewing the camera sensor across from the lens turns. Such optics are handled so that they is held by hand on the ring, thereby held against rotation is. For viewing direction adjustment, the optics relative to the ring turned.
Bei bekannten Optiken dieser Art ist die Schalteinrichtung auf dem Gehäuse des Hauptkörpers angeordnet und dreht somit mit der Optik, was den Bedienungszugriff bei der Schaltbetätigung erschwert.at known optics of this type is the switching device on the housing of the main body arranged and thus rotates with the optics, giving the operating access at the shift operation difficult.
Die Aufgabe der vorliegenden Erfindung besteht darin, bei einer chirurgischen, endoskopischen Optik die Handhabung hinsichtlich des Bedienungszugriffes bei der Schaltbetätigung zu verbessern.The The object of the present invention is, in a surgical, endoscopic optics handling in terms of operating access at the shift operation to improve.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.These The object is achieved with the features of claim 1.
Erfindungsgemäß ist die Schalteinrichtung auf dem Ring angeordnet und somit zusammen mit dem Ring gegenüber dem Hauptkörper drehbar. Das hat große Handhabungsvorteile bei der Bedienung der Schalteinrichtung, da die Schalteinrichtung mit dem Ring stets in derselben Stellung zur bedienenden Hand bleibt, wenn die Optik gedreht wird.According to the invention Switching device arranged on the ring and thus together with the Ring opposite the main body rotatable. That has big Handling advantages in the operation of the switching device because the switching device with the ring always in the same position to operating hand remains when the optics are rotated.
Die schwierige Frage der Abdichtung der Schalteinrichtung und der elektrischen Verbindung von dieser zum Inneren des Gehäuses wird vorteilhaft gemäss Anspruch 2 mit einem kapazitiven oder induktiven Durchgriff durch das Gehäuse gelöst. Ein solcher Durchgriff kann auf einfache Weise unabhängig von der Drehstellung wirkend ausgebildet sein, ohne die Dichtigkeit des Gehäuses zu gefährden. Probleme mit sonstigen elektrischen Drehkontakten, wie z. B. Schleifkontakten, werden vermieden.The difficult question of the sealing of the switching device and the electric Connection of this to the interior of the housing is advantageous according to claim 2 solved with a capacitive or inductive passage through the housing. Such a Penetration can easily act independently of the rotational position be formed without compromising the tightness of the housing. Problems with others electrical rotary contacts, such. B. sliding contacts are avoided.
Vorteilhaft nach Anspruch 3 ist der Ring als Handgriff ausgebildet.Advantageous according to claim 3, the ring is designed as a handle.
Vorteilhaft nach Anspruch 4 erfolgt der kapazitive Durchgriff über konzentrische Ringe, die innerhalb und außerhalb der Gehäusewand angeordnet sind und miteinander Kondensatoren bilden. Dies ergibt eine technisch einfache Konstruktion mit hoher Kapazität.Advantageous According to claim 4, the capacitive penetration via concentric Rings inside and outside the housing wall are arranged and form capacitors with each other. This results a technically simple construction with high capacity.
Vorteilhaft nach Anspruch 5 ist im Ring nur eine rein passive Schaltung angeordnet, die also keine Stromversorgung benötigt. Der versorgungsbedürftige aktive Schaltungsteil in Form einer Messschaltung ist im Inneren des Gehäuses angeordnet, in dem ohnehin elektrische Versorgung gegeben ist, die für sonstige Zwecke, wie z. B. Betrieb der elektrischen Kamera, Lichterzeugung oder dergleichen benötigt wird.Advantageous according to claim 5 is arranged in the ring only a purely passive circuit, So no power needed. The dependent active Circuit part in the form of a measuring circuit is disposed inside the housing, in the already electrical supply is given, for other Purposes such. B. operation of the electric camera, light generation or the like required becomes.
