1877.1877. NITZE in DRESDEN. Urethroskop.NITZE in DRESDEN. Urethroscope. Patentirt im Deutschen Reiche vom 2. December 1877 ab.Patented in the German Empire on December 2nd, 1877. Wie die meisten der bisher zur Untersuchung der männlichen Harnröhre benutzten Instrumente, der sogenannten Endoskope, besteht auch mein Urethroskop aus einer cylindrischen, ungefähr 7 mm starken, 12 cm langen, innen geschwärzten silbernen Röhre, deren eines (inneres) Ende schräg abgeschnitten ist, während das andere (äufsere) von einem verdickten Ringe gebildet wird. Dieses Rohr wird in der bisher üblichen AVeise mittelst eines Obturators möglichst tief in die Harnröhre eingeführt und dann nach Entfernung des Obturators langsam herausgezogen, wobei nach und nach alle Theile der Harnröhren-Schleimhaut vor das innere schräg abgeschnittene Ende des Rohres zuliegenkommenund dann, wenn sie beleuchtet werden, dem Auge sichtbar sind. Während nun diese Beleuchtung bisher dadurch, aber in sehr ungenügender Weise erzielt wurde, dafs man Lichtstrahlen von einer aufsen befindlichen Lichtquelle mittelst eines Reflectors in die Harnröhre hineinwarf, wird bei meinem Instrumente die Lichtquelle selbst tief in die Röhre bis in die unmittelbare Nähe ihres inneren Endes hineingeschoben. Diese Lichtquelle selbst besteht in einem dünnen und kurzen Platindraht, der galvanisch glühend gemacht und erhalten wird und die Theile der Harnröhren-Schleimhaut, die gerade der Oeffnung anliegen, auf das Hellste beleuchtet. Um nun einer Erhitzung des Rohres bezw. der Harnröhren-Schleimhaut vorzubeugen, wird in der gleich zu beschreibenden Weise eine Circulation kalten Wassers um den glühenden Draht unterhalten. Soweit die allgemeine Schilderung der Beleuchtungs-Vorrichtung. Like most of the instruments previously used to examine the male urethra, the so-called endoscopes, my urethroscope also consists of a cylindrical one, roughly 7 mm thick, 12 cm long, inside blackened silver tube, one (inner) end of which is cut off obliquely, while the other (outer) is formed by a thickened ring will. This tube is made as deep as possible by means of an obturator in the usual manner inserted into the urethra and then slowly withdrawn after removing the obturator, gradually all parts of the urethral mucous membrane being obliquely cut off in front of the inner one Come to the end of the pipe and then, if they are illuminated, are visible to the eye. While this lighting has hitherto been but it was achieved in a very inadequate manner that one could get rays of light from one outside Light source thrown into the urethra by means of a reflector is used in mine Instruments the light source itself deep into the tube right up to the immediate vicinity of its interior End pushed in. This light source itself consists of a thin and short platinum wire, which is galvanically made and preserved and the parts of the urethral mucous membrane, which just lie against the opening, illuminated in the brightest possible way. To now one overheating of the pipe respectively. Preventing the urethral mucous membrane will be described in the following Maintain a circulation of cold water around the glowing wire. As far as the general description of the lighting device. Auf das einzelne eingehend, haben wir zunächst einen kurzen, weiten, innen geschwärzten Metalltrichter, dessen schmaler Theil genau, aber ohne Reibung, in die vordere Oeffnung der silbernen Röhre hineinpafst. An die innere Seite des Trichters sind zwei dünne Silberrohre so angelöthet, dafs sie, wenn der Trichter in das Rohr gesteckt ist, hart an. dessen innerer Wand und in einem Abstand von 3 mm parallel nebeneinander bis fast an das innere, schräg abgeschnittene Ende verlaufen, um dort bogenförmig ineinander umzubiegen und so eine einzige Röhre zu bilden.Going into detail, we first have a short, wide one that is blackened on the inside Metal funnel, the narrow part of which fits precisely, but without friction, into the anterior opening of the silver tube fits into it. On the inside of the funnel are two thin silver tubes so soldered that when the funnel is inserted into the tube, it is hard on. its inner Wall and at a distance of 3 mm parallel to each other up to almost the inside, diagonally cut ends run in order to bend into each other in an arc and such a thing single tube to form. Durch diese Röhre circulirt während des Glühens des Platindrahtes der oben erwähnte continuirliche Strom kalten Wassers. Zu diesem Zweck sind die beiden Enden des Rohres am Trichter mit zwei rechtwinklig zu diesem und parallel nebeneinander abgehenden Ansätzen versehen, auf welche die beiden Gummischläuche geschoben werden, von denen der eine das Wasser aus einem Irrigator zu- der andere ableitet. Zwischen den beiden Silberröhren verläuft, allseitig durch eine dünne Schellackschicht isolirt, ein schmaler Silberstreifen, um ungefähr 5 mm über der bogenförmigen Verbindung der Röhren zu endigen.The above-mentioned circulates through this tube while the platinum wire is glowing Continuous flow of cold water. For this purpose the two ends of the tube are on the funnel with two attachments going off at right angles to this and parallel to each other on which the two rubber hoses are pushed, one of which is the Drains water from one irrigator to the other. Runs between the two silver tubes, insulated on all sides by a thin layer of shellac, a narrow silver stripe, about To end 5 mm above the arched connection of the tubes. In dieses Ende ist ein kleines Loch eingeschlagen, welches gestattet, eine feine kurze Platinschlinge zum Bogen herüber zu spannen. Dieser Platindraht bildet, wenn er durch Schliefsen des Stromes glühend gemacht wird, die oben erwähnte Lichtquelle. Zu dem einen Ende des Drahtes wird der Strom durch den Silberstreifen geleitet, der am Trichter, gegen den er ebenfalls isolirt ist, dicht neben den Ansätzen der wasserleitenden Röhren, in einen kurzen starken Draht zum Anschrauben der einen stromleitenden Schnur endigt. Für die andere ist am Trichter ein ebenfalls kurzer Draht angelöthet, durch den der Strom durch die wasserleitenden Röhren zum anderen Ende des Platindrahts gelangt. A small hole is hammered into this end, which allows a fine, short one To stretch the platinum loop over to the bow. This platinum wire forms when it closes of the stream is made glowing, the above-mentioned light source. To one end of the With the wire, the current is conducted through the silver lining on the funnel, against which it is also is insulated, close to the beginnings of the water-conducting tubes, in a short, strong one Wire for screwing on the one conductive cord ends. For the other is on Also a short wire is soldered to the funnel, through which the current flows through the water-conducting Tubes to the other end of the platinum wire. Die Anwendung des Instrumentes ist eine einfache: Nachdem das Rohr mit dem Obturator eingeführt und letzterer wieder herausgezogen ist, wird der Trichter mit dem Beleuchtungsapparat eingeschoben, der Strom geschlossen, und dann beim Zurückziehen des Instrumentes die Schleimhaut mit dem vor dem Trichter befindlichen Auge des Beobachters betrachtet.The use of the instrument is simple: after the tube with the obturator inserted and the latter pulled out again, the funnel with the lighting device is pushed in, the power is closed, and then, when the instrument is withdrawn, the mucous membrane with the one in front of the funnel eye of the observer located.
