Abstract

Kryogenes System für kryochirurgische Eingriffe im human- and veterinärmedizinischen Bereich, insbesondere in der Tumorbehandlung, bestehend aus einem Kryostat (1) und einer Verbindungsanordnung (8) zwischen den koayialen kryogenen Leitungen für den Direkt- (9) und Rückstrom (10) des kryogenen Mediums zum Verbinden eines Kryoinstrumentes (17) mit einem Kryoansatz (13). Das elektomagnetische Ventil (11) befindet sich in unmittelbarer Nähe der Verbindungsanordnung (8). Eine Regelungsvorrichtung (18) ist zur Steuerung der elektromagnetischen Ventile (2, 3, 4 und 7) sowie des Heizelementes (12) vorgesehen, die den Überdruck des kryogenen Mediums im Kryostat (1) auf eine Genauigkeit von ± 0,1x105 Pa einstellt. Der Flaschenhals (23) des Kryostates (1) ist aus einem Material mit geringer Wärmeleitung hergestellt. Zur exakten Abdichtung zwischen den koaxialen Leitungen (9) und (10) sind kegelstrumpfförminge, miteinander korrespondierende Verbindungselemente (30, 31) innerhalb der Leitung (10) sowie kegelstumpfförmige, miteinander korrespondierende Verbindungselemente (34, 35) innnerhalb der Leitung (9) und eine elektrische Leitung (36) für eine elektrische Verbindung bzw. Unterbrechung zwischen beiden Leitungen (9, 10) vorgesehen.
