Description
Handstück für Hochfrequenz-Elektroden.
Die Erfindung bezieht sich auf ein Handstück für Hochfrequenz-Elektroden,
insbesondere für die Hochfrequenzchirurgie, mit eingebauten Steuerschaltern zur Steuerung eines Hochfrequenz-Generators
im Sinne einer Änderung seiner Ausgangsenergie, Frequenz od.dgl..
Bekannte Handstücke der genannten Art haben mechanische Schaltkontakte,
die durch Druckknöpfe oder Kippschalter zu betätigen sind. Ferner sind Handstücke bekannt, die durch Drehen einer
aufgesetzten Muffe mit eingelegten Schleifringen eine Steuerung des Generators erlauben.
Die bekannten Ausführungen haben dan Nachteil eines verhältnismäßig
komplizierten Aufbaues, schleichender Kontaktgabe, unter Umständen auch ungenau arbeitender Schaltstellungen und
mechanischer sowie elektrischer Verschleißerscheinungen an den Kontakten.
Aufgabe der Erfindung ist es, diese Nachteile uu beseitigen, R.1 so den Aufbau bei erhöhter Batriebssieheaeheit zu vereinfachen.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Steuerschalter magnetfeldabhängige Kontaktelemente verwendet sind
und im Handstück ein mit einer Handhabe verbundener Dauermagnet angeordnet ist. Neben einem einfachen Aulbau sowie einer einfachen und gefahrlosen Bedienung ergibt sich vor allein der
Vorteil hoher Kontaktsicherheit, bei eindeutigen Schalv-Stellungen.
Von Vorteil ist es, den Magnet an oder in einer als Schieber ausgebildeten Handhabe anzuordnen. Weiterhin ist es verteil»
haft, den Schieber mit Rückstellfedern so zu belasten, daß er aus einer bestimmten Nullage linear in die Arbeitsstellung auelenkbar ist und die Steuerung des Hochfrequenz-Generators in
der Weise auszubilden, daß mit der Auelenkung des Magneten über
die Kontakte!emente zugleich der Generator eingeschaltet wird.
Als Steuerschalter werden zweckmäßig in Schutzgas eingebettete Kontaktelemente, sogenannte Reed-Kon .akte, verwendet.
g Anhand der Zeichnung wird ein ^usführungsbeispiel der Erfindung
erläutert.
Die Fig. 1 und 2 zeigen im Auf- und Grundriß zum Teil im Schnitt ein Handstück mit einem im Gehäuse 1 angeordneten,
in Form eines schmalen, dünnen Bleches 2 ausgebildeten Hochfrequenz-Leiter, der das Hochfrequenzkabel 3 mit der in eine
Metallbuchse 4 eingesetzten Hochfrequenz-Elektrode 5 verbindet. Unmittelbar über dem Hochfrequenz-Leiter 2 befindet sich eine
Kunststoffplatte 6, welche fest mit dem Gehäuse 1 verbunden 1st. In die Kunststoffplatte 6 sind versetzt zwei Reed-Kontakte 7 und 8 eingegoseen. Die Kontakte 7 und 8 steuern den
Hochfrequenz-Generator über die Steuerleitungen 9 und 10 sowie
Über den als gemeinsamen Rückleiter für die Steuerleitungen dienenden Hochfrequenz-Leiter 2 derart, daß bei geschlossenem
Kontakt 7 der Hochfrequenz-Generator z.B. auf Koagulationsbetrieb und bei geschlossenem Kontakt θ auf Schneidbetrieb
geschaltet ist. Bei offenen Kontakten ist der Hochfrequenz-Generator abgeschaltet.
Die Anwahl "Schneiden" oder "Koagulation" erfolgt durch einen
in dem Schieber 11 engeordneten Dauermagneten 12. Wird der
Schieber 11 in Richtung des Pfeiles 13 bis zum Anschlag H
des PUhrungateiles 15 gegen die Kraft der Feder 16 ausgelenkt,
so kommt der Dauermagnet 12 unmittelbar über den Kontakt θ
und bewirkt dessen Schließung.
Wird der Schieber 11 in Richtung des Pfeiles 17 bis zum Anschlag 18 des FUhrungstellee 15 gegen die Kraft der Feder
verschoben, so kommt der Dauermagnet 12 unmittelbar über den Kontakt 7, so daß dieser nunmehr geschlossen wird. In der
durch die Federn 16, 19 bestimmten Nullage des Schiebers 11 (gezeichnete Lage) befindet eich der Magnet in einer Zwischenstellung zwischen den Kontakten 7 und 8. Beide Kontakte sind
in dieser Stellung des Magneten 12 gec '.et, d.h. der Hochfrequenz-Generator ist ausgeschaltet, die Bohrung 20 dient
zum Yerschrauben des Führungsteiles 15 mit dem Block 6.
