Description
DEUTSCHESGERMAN
Die Innenwand des Herzens und der Blutgefäße dem Auge auf dem Wege einer Endoskopie sichtbar zu machen, erscheint zunächst unmöglich wegen der Undurchsichtigkeit der Blutflüssigkeit, die die Blutbahn überall erfüllt. Man wäre schon gezwungen, den Blutstrom zeitweilig abzulenken, also den Ort der Betrachtung aus der Blutzirkulation zeitweilig auszuschalten, um ihn so für den zur Endoskopie erforderlichen operativen Eingriff sichtbar und zugänglich zu machen.The inner wall of the heart and blood vessels are visible to the eye through an endoscopy To make it seem impossible at first because of the opacity of the blood fluid that makes up the bloodstream met everywhere. One would be forced to divert the blood flow temporarily, that is, the location temporarily switch off the observation from the blood circulation in order to make it necessary for the endoscopy to make surgical intervention visible and accessible.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, das Endoskop mit Vorrichtungen für die Zuführung einer optisch klaren Flüssigkeit zur inneren Endoskopoptik zu versehen, wobei die Flüssigkeit unter einem Druck zugeführt wird, der den x5 Blutdruck in dem zu untersuchenden Gefäßsystem übertrifft. Beispielsweise wird in folgender Weise vorgegangen:To solve this problem it is proposed according to the invention to provide the endoscope with devices for supplying an optically clear liquid to the inner endoscope optics, the liquid being supplied at a pressure which exceeds the x5 blood pressure in the vascular system to be examined. For example, the procedure is as follows:
Mit einem relativ zum Blutdruck höheren und hinreichend hohem Drucke strömt Wasser mit eventuell 2C physiologischen Zusätzen aus dem Beobachtungsinstrument und lagert sich in dem Raum zwischen Optik des Instrumentes und Beobachtungsobjekt, z.B. Herzwand, Herzklappen usw., indem es das dort anwesende Blut verdrängt. Durch die so gebildete a5 Wasseransammlung, die während der Beobachtung unentwegt ergänzt werden muß, da sie sofort mit dem Blut — sich mischend — abfließt, wird die Beobachtung der von Blut entleerten Gefäße ermöglicht.With a higher and sufficiently high pressure relative to the blood pressure, water with possibly 2C physiological additives flows out of the observation instrument and is stored in the space between the optics of the instrument and the object to be observed, e.g. heart wall, heart valves, etc., by displacing the blood present there. The a5 water accumulation formed in this way, which has to be constantly replenished during the observation, since it flows off immediately with the blood - mixing - enables the observation of the blood-emptied vessels.
Den erforderlichen Überdruck der Kontaktflüssigkeit gegenüber dem Blut erreicht man leicht durch entsprechendes Heben des Behälters, der die Flüssigkeit, z. B. Ringerlösung, enthält. Bereits auf diesem etwas primitiven Wege ist es möglich, ohne Schwierigkeit einen Überdruck von 1A bis Va atü zu erzielen. Für die Praxis empfiehlt sich die Erzeugung eines Überdruckes mittels motorischer Hilfen, wobei die elektrisch getriebene Pumpe wegen ihrer Geräusche weniger angenehm erscheint als der mittels einer Gasflasche erzeugte Überdruck. Hierbei kann auch Sauerstoff aus dem Narkosegerät verwendet werden. Die Verwendung des Gasüberdruckes macht eine Sicherung des Abflusses des Flüssigkeitsbehälters gegen völlige Entleerung und Gasdurchstrom notwendig, was leicht mittels eines Schwimmerventils, das sich kurz vor der Entleerung abdichtend in den Abflußkanal senkt, in an sich bekannter Weise möglich ist.The required overpressure of the contact liquid with respect to the blood can easily be achieved by lifting the container that holds the liquid, e.g. B. Ringer's solution contains. Even in this somewhat primitive way it is possible to achieve an overpressure of 1 A to Va atü without difficulty. In practice, it is advisable to generate an overpressure by means of motor aids, whereby the electrically driven pump appears less pleasant because of its noises than the overpressure generated by means of a gas cylinder. Oxygen from the anesthesia machine can also be used here. The use of the gas overpressure makes it necessary to secure the outflow of the liquid container against complete emptying and gas flow, which is easily possible in a manner known per se by means of a float valve, which lowers into the drainage channel to form a seal shortly before emptying.

Cystoskopoptik von bekannter Bauart. Das Rohr a ist an seiner in die Körperhöhle einzuführenden Öffnung mit einer ein- und ausschwenkbaren Beleuchtungsquelle b ausgestattet. Das Rohr α trägt ein sehr feines Messer n, das durch einen Elektromotor e im Handstück mittels Exzenterübertragung f in oszillierende Schneidebewegungen versetzt werden kann. Mittels eines außerdem durch Bowdenzug Jf1 zu betätigenden Greifers g2 kann beispielsweise Gewebe erfaßt und mit Hilfe des eben erwähnten Messers chirurgisch entfernt werden. Mit k ist die Stelle für weitere elektrische Anschlüsse bezeichnet, während die Öffnung i die Zuiiußöffnung für das optisch klare Medium, also eine Wasser- oder Salzlösung, darstellt. Anstatt eines mechanisch bewegten Messers können natürlich andere Arten von Instrumenten zusätzlich verwendet werden, z. B. eine Diathermienadel. Beispielsweise Einstichrichtungen sind mit c und d bezeichnet. Cystoscope optics of known design. The tube a is equipped at its opening to be introduced into the body cavity with an illumination source b that can be swiveled in and out. The tube α carries a very fine knife n, which can be set in oscillating cutting movements by an electric motor e in the handpiece by means of eccentric transmission f. By means of a gripper g 2 which can also be actuated by Bowden cable Jf 1 , tissue can, for example, be grasped and surgically removed with the aid of the knife just mentioned. The point for further electrical connections is designated by k , while the opening i represents the inlet opening for the optically clear medium, that is to say a water or salt solution. Instead of a mechanically moved knife, other types of instruments can of course also be used, e.g. B. a diathermy needle. For example, puncture directions are denoted by c and d.
