Description
Einrichtung zur Erzeugung hochfrequenter elektrischer Ströme Bei der chirurgischen Anwendung der hochfrequenten elektrischen Ströme ist es erwünscht, den Körper des Patienten während der Operation zu durchwärmen. Für diesen Zweck hat man neben dem chirurgischen Diathermieapparat einen besonderen Diathermieapparat für Durchwärmung verwendet. Es ist auch bekanntgeworden, für diesen Zweck zwei unabhängig voneinander arbeitende Diathermieapparate zu einem Großapparat in gemeinsamem Gehäuse zu vereinigen. Derartige Anordnungen sind aber kostspielig. Sie nehmen viel Platz ein und sind umständlich in der Bedienung.Device for generating high-frequency electrical currents in the surgical application of high-frequency electrical currents, it is desirable warm the patient's body during the operation. For this purpose In addition to the surgical diathermy device, you have a special diathermy device used for soaking. It has also become known to be two independent for this purpose Diathermy apparatus working from one another to form a large apparatus in a common housing to unite. However, such arrangements are costly. They take up a lot of space and are cumbersome to use.
Da die Zeitdauer der Inanspruchnahme eines chirurgischen Diathermieapparates gegenüber der Gesamtdauer einer Operation verhältnismäßig klein ist, genügt es, den Patienten nur in den Operationspausen (also solange der chirurgische Diathermieapparat für die Operation selbst nicht benötigt wird) zu durchwärmen.Since the duration of use of a surgical diathermy device is relatively short compared to the total duration of an operation, it is sufficient the patient only during the breaks in the operation (i.e. as long as the surgical diathermy device is not needed for the operation itself).
Die bekannten Apparate, die für chirurgische Zwecke und für Durchwärmung bestimmt sind, können nicht ohne weiteres verwendet werden, denn sie besitzen keine besonderen, unabhängig voneinander regulierbaren und abschaltbaren Stromkreise für chirurgische Arbeiten und für Durchwärmung. Wollte man mit ihnen den Patienten in den Pausen zwischen den chirurgischen Eingriffen durchwärmen, so müßte man sehr häufig Änderungen an den Anschlußleitungen vornehmen unter gleichzeitiger Neueinstela lung der Regulierorgane, um eine für Chirurgie oder Durchwärmung passende Leistung einzustellen. Eine derartige Betriebsweise würde praktisch unmöglich sein.The known apparatus, which are intended for surgical purposes and for soaking, cannot be used without further ado, because they have no special, independently adjustable and disconnectable circuits for surgical work and for soaking. If you wanted to warm up the patient with them in the breaks between the surgical interventions, you would very often have to make changes to the connecting lines in front with simultaneous re-setting of the regulating organs in order to set a performance suitable for surgery or warming. Such an operation would be practically impossible.
Gemäß der vorliegenden Erfindung wird ein chirurgischer Hochfrequenzapparat mit mindestens einem Elektrodenhandgriff dadurch zum Durchwärmen eines Patienten während der Pausen zwischen den chirurgischen Eingriffen verwendbar gemacht, daß Vorrichtungen vorgesehen sind, die den Strom in dem Stromkreis für die Durchwärmung schwächen oder unterbrechen, sobald ein Stromkreis für chirurgische Arbeiten geschlossen wird.In accordance with the present invention, there is provided radio frequency surgical apparatus with at least one electrode handle for warming up a patient made usable that during the breaks between surgeries Devices are provided to keep the current in the circuit for soaking weaken or interrupt as soon as a surgical circuit is closed will.
Gegenüber den bekannten Einrichtungen wird der Vorteil erzielt, daß das chirurgische Arbeiten und das Durchwärmen mit nur einem Apparat praktisch und bequem ausführbar ist und fernerhin statt der kostspieligen Apparate mit getrennten Einrichtungen ein Apparat mittlerer Leistung verwendbar wird. Weitere Vorteile ergeben sich daraus, daß nicht Energie in Ballastkreisen verlorengeht oder Apparateteile, wie Funkenstrecke, Kondensatoren u. dgl., eine derartige Erwärmung erfahren, daß ein merklicher Leistungsrückgang des Apparates eintritt.Compared to the known devices, the advantage is achieved that Surgical work and warming up with just one device are practical and can be carried out conveniently and, furthermore, instead of the expensive apparatuses with separate ones Facilities an apparatus of medium power can be used. Further advantages result from the fact that energy is not lost in ballast circuits or parts of the apparatus, such as spark gaps, capacitors, etc., experience such heating that there is a noticeable decrease in the performance of the apparatus.
Eine beispielsweise Ausführungsform der neuen erfindungsgemäßen Einrichtung ist in der Abbildung der Schaltungsanordnung nach dargestellt.An example embodiment of the new device according to the invention is shown in the figure of the circuit arrangement according to.
Der Hochfrequenzstrom wird in der an sich bekannten Weise mittels eines von einem Hilfsstromkreis a gespeisten Relais h für einen Umschalter b von dem am Elektrodenhandgriff e angebrachten Fingerschalter d aus auf die Stromregulierung e bzw. auf den Ballastwiderstand f umgeschaltet. Beim Drücken auf den Fingerschalter d wird der Schalthebel des Umschalters b angezogen und die Stromregulierung e in den Hochfrequenzstromkreis eingeschaltet, während der Ballastwiderstand f stromlos wird.The high frequency current is in the at known each other Way by means of a relay h fed by an auxiliary circuit a for a changeover switch b from the finger switch d attached to the electrode handle e to the current regulation e or switched to the ballast resistor f. When pressing the finger switch d the switching lever of the switch b is pulled and the current regulation e in the high-frequency circuit switched on, while the ballast resistor f is de-energized will.
Bei dieser Stellung des Umschalthebels steht die volle Apparateleistung für die Operation zur Verfügung, und es kann der Hochfrequenzstrom für die Operationselektrode g an der Klemme l des Apparates entnommen werden. Die inaktive Elektrode wird, wie üblich, an die Klemme o angeschlossen.When the switch lever is in this position, the machine is at full power available for the operation and it can use the high frequency current for the operation electrode g can be taken from terminal l of the device. The inactive electrode is how usual, connected to terminal o.
Beim Loslassen des Fingerschalters d geht der Schalthebel des Umschalters bin die gezeichnete Stellung zurück, und die Operations= elektrode g wird stromlos. Der Hochfrequenzstrom geht dann durch den Ballastwiderstand, dem erfindungsgemäß die Stromregelvorrichtung la parallel geschaltet ist. Der bewegliche Kontaktteil m führt zu der Klemme 2, an die eine für die Durchwärmung dienende Elektrode angeschlossen werden kann.When the finger switch d is released, the switching lever of the switch goes off am back to the position shown, and the operation electrode g is de-energized. The high-frequency current then goes through the ballast resistor according to the invention the current control device la is connected in parallel. The moving contact part m leads to terminal 2, to which an electrode used for heating is connected can be.
In dem erläuterten Ausführungsbeispiel_ ist nur eine Stromanschlußstelle für einen Elektrodenhandgriff angegeben. Es können auch mehrere Stromanschlußstellen für verschiedene Elektrodenhandgriffe vorhanden sein. In diesem Falle sind auch mehrere Umschalter b und Relais k erforderlich, die in bekannter Weise in Serie geschaltet werden, so daß der Hochfrequenzstrom erst dann zum Durchwärmen verfügbar wird, wenn sämtliche chirurgischen Elektroden abgeschaltet sind.In the illustrated embodiment, only one power connection point for an electrode handle is specified. There can also be several power connection points for different electrode handles. In this case, several changeover switches b and relays k are required, which are connected in series in a known manner, so that the high-frequency current is only available for warming up when all surgical electrodes are switched off.
