Abstract

The circuit which automatically switches on the high-frequency current of a coagulation instrument has two leads. The first (1) is connected to a potention-meter (P1), whose other terminal has a 9-volt potential applied to it, while the second (2) is connected via a resistance (R2) to the base of a transistor (T1). A second resistance (R3) connects this lead to the neutral point of the voltage source. The base of the transistor (T1) is earthed via a capacitor (C1), while the +9-volt supply is applied to the collector through a third resistance (R1), and its emitter is earthed. Its collector is connected via a second potentiometer (P2) and a fourth resistance (R4) to the base of a second transistor (T2). The second transistor collector terminal leads via a relay (Rel) and a diode (D1), in parallel, back to the first transistor collector. The connecting point between the second potentiometer and the fourth resistance is earthed via a second capacitor (C2).

Description

Schaltung zur automatischen Einschaltung des HochfrequenzstremenCircuit for automatic activation of high-frequency currents

von Hochfrequenz-Koagulationegeräten.of high-frequency coagulation devices.

Die erfindung betrifft eine Schaltung des Hochfrequenzstromes von llochfrenuenz-Koagulationsgeräten, die in der Chirurgie zum Verschließen von Blutgefäben Verwendung finden (z.P. Bipolatoren) Bei den derzeit auf dem Markt befindlichen Geräten wird dabei der Koagulationsstrom stets durch mechanische Schalter eingeschaltet.The invention relates to a circuit of the high frequency current of Oil-free coagulation devices used in surgery to close blood vessels Use (e.g. bipolators) for those currently on the market Devices, the coagulation current is always switched on by mechanical switches.

Es hnndelt sich dabei entweder um Fußschalter oder um Schalter an Pinzettengriff.It is either a foot switch or a switch Tweezer handle.

Diese Art Schalter besitzen große Nachteile. Da der Fußschalter am Boden gelagert ist, muß er wie gesetzlich vorgeschrieben, explosionsgeschützt ausgeführt sein. Der Aufwand dafür iet erheblich das Gerät verteuert sich, und die Bedienung ftshrt, wie die Praxis gezeigt hat, besonders bei der Fußschalter-Ausführung zur Ermüdung des Betätigers. Der Nachteil des Schalters am rinzettengriff liegt darin, das die HF-Einschaltung nur bei einem bestimmten Abstand der ninzettenschenkel möglich ist. Gefäße verschiedener Starke können deshalb nicht optimal koaguliert werden. in weiterer Wachteil ist das erhöhte Gewicht der Pinzette, was die Handhabung besonders in der Mikrochirurgie erschwert. Ferner besteht die Gefahr der Kontaktoxidation.This type of switch has major disadvantages. Since the foot switch on the If the floor is stored, it must be designed to be explosion-proof as required by law be. The effort for this makes the device much more expensive, and the operation As practice has shown, this particularly applies to the foot switch version Operator fatigue. The disadvantage of the switch on the tweezer handle is that that the HF activation is only possible with a certain distance between the tweezers legs is. Vessels of different strengths cannot therefore be optimally coagulated. Another disadvantage is the increased weight of the tweezers, which makes handling special difficult in microsurgery. There is also the risk of contact oxidation.

Der vorliegenden Erfindung liest deshalb die Aufgabe zugrunde, eine Schaltungsanordnung zu schaffen, die automatisch nach einer einstellbaren Verzögerung den Hochfrequenzstrom bei Gewebekontakt der Pinzettenspitzen am gewünschten Punkt einschaltet. Die integrierte Verzögerungsschaltung verhindert ein flinschalten bei unbeabschtigtem kurzem Cewebekontakt der Pizettenspitzen oder bei kurzen Manipulationen im Gewebe.The present invention therefore reads the object of a To create circuitry that automatically after an adjustable delay the high-frequency current when the forceps tips come into contact with tissue at the desired point turns on. The integrated delay circuit prevents a flip switch at short unintentional tissue contact of the pizza tip or during brief manipulations in the tissue.

Die Aufgabe wird durch die im Anspruch I angegebene Erfindung gelöst.The object is achieved by the invention specified in claim I.

Die erfindungsgemäße Schaltung besitzt den Vorteil, daß sie einfach und damit billiT herstellbar ist und eine optimale Handhabung der Koagulationpinzette gewährleistet.The circuit according to the invention has the advantage that it is simple and thus can be produced cheaply and optimal handling of the coagulation forceps guaranteed.

Funktionsbeschreibung Berühren die Pinzettenspitzen das zu verschließende Blutgefäß, so fließt Uber das Potentiometer (P1), durch das Gewebe und über den Widerstand (R2) ein Basissteursstrom, der den Darlingtontransistor (T1) durchschaltet. Der maximale Gewebestroia beträgt dabei ca. 30 ul. Functional description Touch the tips of the tweezers to be closed Blood vessel, so flows over the potentiometer (P1), through the tissue and over the Resistor (R2) a basic control current that switches the Darlington transistor (T1) through. The maximum tissue estroia is about 30 μl.

Der negative Spannungssprung am Kollektor des Transistors (T1) wird erst nach einer entsprechenden Umladung des londensators (C2) über das Potentiomater (P2) und den Widerstand (54) an der basis des Transistors (T2) wirksam. Dieser Transistor schaltet nun ebenfalls nach einer mittels des Dotentiometers (E2) einstellbaren Verzögerung durch, und es fließt so lange Strom durch das Relais (Rel) wie der Transistor (T1) infolge Gewebekontakt der Pinzettenspitzen durchgeschaltet ist. Wird die Pinzette aus dem Gewebe entfernt, so sperrt augenblicklich der Transistor (T1) und das Relais (Rel) fällt ab, obwohl der Transistor (T2) noch bis zur erneuten Umladung des Kondensators (C2) durchgeschaltet ist. as iielais (Rel) schaltet über seine zugehörigen Kontakte den HF-Koagulator nur dann ein, wenn beide Transistoren durchgeschaltet sind, d.h. wenn die linbettenspitten Gewebekontakt haben und eine einstellbare Verzögerungszeit abgelaufen ist. (UND-Funktion ) Die Widerstände (R2u.P3) sowie der Kondensator (C1) begrenzen den HF-3tron bei eingeschaltettem Koagulator, der als Basisstrom des Traneistors (T1) # zusätzlich wirksam wird und verhindern einen "Halteeffekt" der Schaltung bei unterbrochenem Gewebekontakt der Pinzetenspitzen.The negative voltage jump at the collector of the transistor (T1) is only after reloading the capacitor (C2) via the potentiometer (P2) and the resistor (54) at the base of the transistor (T2) effective. This transistor now also switches according to a setting that can be set using the dotentiometer (E2) Delay through, and current flows through the relay (Rel) as long as the transistor (T1) is switched through due to tissue contact of the forceps tips. Will the tweezers removed from the tissue, the transistor (T1) and the relay block immediately (Rel) drops, although the transistor (T2) is still charged until the capacitor is recharged again (C2) is switched through. The relay (Rel) switches via its associated contacts only switch on the HF coagulator when both transistors are switched on, i.e. when the linbettenspitten have tissue contact and an adjustable delay time has expired. (AND function) The resistors (R2u.P3) and the capacitor (C1) limit the HF-3tron when the coagulator is switched on, which acts as the base current of the Traneistor (T1) # is additionally effective and prevent a "hold effect" of the circuit with interrupted tissue contact of the forceps tips.

Die Diode (D1) schützt den Transistor (T2) vor induktiven Ausschaltspannungsspitzen.The diode (D1) protects the transistor (T2) from inductive switch-off voltage peaks.
