Mittels der dargestellten und beschriebenen Vorrichtung wird die Flüssigkeit aus dem Vorratsbehälter 22 durch die Perfusionsschlauchleitung 23, 24 und 25 zum Arthroskop 21 und damit in die Körperhöhle des Kniegelenks 20 gepumpt Der Perfusionsschlauch 23,24 liegt im Bereich der Rollenradpumpe 14 zwischen dem RdI-lenrad 13 und einer etwa halbkreisförmigen Kurve des Abrollbügels 12 und wird mittels der Rollen 28 des Rollenrades 13 gegen den Abrollbügel 12 zur Erzielung einer Pumpwirkung gedrückt Die Perfusionsmenge kann mittels des Drehknopfes 7 am Perfusionsmengenregler 18 eingestellt werden. Der Sollwert des Arbeitsdruckes der Flüssigkeit kann mittels des Drehknopfes 1 am Sollwert-Druckgeber 19 eingesteiü werden. Der Antriebsmotor der Rollenradpumpe 14 iti elektronisch drehzahlstabilisiert so daß die vorgewählte Drehzahl auch bei ansteigendem Druck erhalten bleibt Der Istwert des Arbeitsdruckes der Flüssigkeit innerhalb der Körperhöhle im Kniegelenk 20 wird mittels des Druckaufnehmers 15 ermittelt Solange der am Druckaufnehmer 15 gemessene Istwert nicht den am Druckgeber 19 eingestellten Sollwert erreicht, läuft die Pumpe 14. Sobald der Istwert des Druckes den eingestellten Sollwert erreicht, wird die Pumpe 14 ausgeschaltet Dadurch ist während der gesamten Betriebszeit die Druckbeaufschlagung der Körperhöhle im Knie 20 konstant. Die Perfusionsmenge der Flüssigkeit selbst wird durch den Perfusionsmengenregler 18 konstant gehalten, solange die Pumpe 14 läuftBy means of the device shown and described, the liquid is removed from the storage container 22 through the perfusion tubing line 23, 24 and 25 to Arthroscope 21 and thus pumped into the body cavity of the knee joint 20. The perfusion tube 23, 24 is located in the area of the roller pump 14 between the RdI-lenrad 13 and an approximately semicircular curve of the Abrollbügel 12 and is achieved by means of the rollers 28 of the roller wheel 13 against the Abrollbügel 12 a pumping action. The perfusion quantity can be adjusted by means of the rotary knob 7 on the perfusion quantity regulator 18 can be set. The nominal value of the working pressure of the liquid can be adjusted by means of the rotary knob 1 be adjusted at the setpoint pressure transmitter 19. The drive motor the roller pump 14 iti electronically speed-stabilized so that the preselected speed The actual value of the working pressure of the liquid within the is retained even when the pressure rises The body cavity in the knee joint 20 is determined by means of the pressure sensor 15 as long as the pressure sensor 15 does not reach the setpoint set on the pressure transmitter 19, pump 14 runs as soon as If the actual value of the pressure reaches the setpoint value, the pump 14 is switched off During the entire operating time, the pressurization of the body cavity in the knee 20 is constant. the Perfusion amount of the liquid itself is kept constant by the perfusion amount regulator 18 as long as the pump 14 is running
In den Perfusionsschlauch 23,24 ist in Strömungsrichtung unmittelbar hinter der Pumpe 14 ein Schlauchstück 31 aus zwei ineinandergesteckten Schläuchen 32, 33 eingesetzt, welche an ihren beiden Enden luftdicht miteinander verbunden sind und ein Luftpolster um den inneren dünnen Schlauch 32 herum bilden. Das Schlauchstück 31 bildet somit ein Dämpfungsglied für den Perfusionsschlauch 23,24, indem beim Einschalten der Pumpe 14 zunächst das Luftpolster im Schlauchrwück 31 aufgebaut werden muß, welches beim Abschalten der Pumpe 14 wieder abgebaut wird, wodurch der Systemdruck im Perfusionsschlauch langsam abgebaut wird.In the perfusion tube 23, 24, immediately behind the pump 14, a tube piece 31 consisting of two tubes 32, 33 plugged into one another is inserted, which are hermetically connected at both ends and form an air cushion around the thin inner tube 32. The tube piece 31 thus forms a damping element for the perfusion tube 23, 24, in that when the pump 14 is switched on, the air cushion must first be built up in the tube back 31, which is reduced again when the pump 14 is switched off, whereby the system pressure in the perfusion tube is slowly reduced.
Wie es die F i g. 2 zeigt, muß der Istwert-Druckaufnehmer 15 in gleicher Höhe mit dem Kniegelenk 20 eingestellt werden (.strichpunktierte Linie), so daß der Istwert-Druckaufnehmer 15 tatsächlich auch den aktuellen Druck in der Körperhöhle des Kniegelenks 20 mißtAs shown in FIG. 2 shows, the actual value pressure sensor 15 must be at the same height as the knee joint 20 set (. dash-dotted line) so that the Actual value pressure transducer 15 actually also shows the current pressure in the body cavity of knee joint 20 measures

This device values electronics the further perfusion. The body cavity comprises several, working with floating bodies is thereby acted upon at least up to the preselected target value directions to control the flow and the working pressure so that the invention pressure as well as to limit the fluid pressure. This device has the disadvantage that each individual body cavity maximum permissible pressure with safety device prevents it from being set by hand by itself. Due to the precise controllability of the arm, so that neither a clear and precise metering pressure of the fluid in the body cavity nor a precise setting prevents an irreversible overstretching of the knee joint from decreasing the fluid pressure in the operating area. Since the pressure sensor and control circuit are possible on the inflow, or are arranged through the side of the peristaltic pump only with great effort, it will be able to be guided. The known device adapts the volume flow of the liquid while the peristalsis is running, and furthermore does not automatically keep the pump constant in the desired size to the required conditions. Here in the operating area. In addition, the pump is achieved by ensuring that a constant fluid itself does not flow continuously through the body cavity, in this case the gate part, in the control and regulating processes of the irriga- tion, so that it flows out of the pump Arthrofene pressure fluctuations additionally by hand to the scopy a removal of the peeled cartilage material facilities for the control and limitation of the flow is ensured. Finally, the constant permeability pressure and the amount of liquid that adjusts to the amount of liquid also give a clear view of the need to be lubricated.
