- the RF surgical instrument can be, for example, an instrument for argon plasma coagulation or HF cutting, which acts on the biological tissue 5 of a patient to be treated by means of one or more active electrodes. That too
- the electrosurgical unit 1 further comprises a power supply 7, which converts the mains voltage (50 Hz AC) into a voltage suitable for the HF generator.
- the high frequency power is generated at a carrier or fundamental frequency and in downstream
- the generated by the RF generator 3 the fundamental frequency having output signal over time, in particular modulated with a variable duty cycle.
- a modulation device 9 it is possible either to act directly on the HF generator 3 by means of a modulation device 9 in such a way that the same is modulated by pulsing or pressing the high-frequency power, ie by corresponding switching on and off of the output signal.
- PWM Pulse width modulation
- the H F generator for example, have a circuit arrangement with MOSFET transistors, which are alternately turned on and off.
- the control of the modulation device 9 is usually carried out by a control device 11.
- Another known way to modulate the output signal is a direct drive of the power supply 7 by means of the control device 11. This makes it possible to modulate the amplitude of the output signal of the H F generator 3, wherein the controller 11 has an effect as
- Modulation device 9 has.
- the fundamental frequency of the H F generator is usually about 300 to 500 kHz.
- the modulation usually takes place with frequencies between 1 kHz and 50 kHz. Preferably, however, modulation frequencies greater than 20 kHz are used to avoid the generation of unpleasant noises.
- H F surgical devices require that low-frequency current components that can flow through the patient and thus trigger neuromuscular stimulation (eg muscle twitching) must be limited to very low values. If this requirement is met, certain application parts may be referred to as CF (Cardiac Floating).

- Modulation frequencies even at a fundamental frequency of greater than 200 kHz must be taken into account, because they clearly emerge in the frequency spectrum of the entire output signal and thus can cause neuromuscular phenomena.

- Output signal of the H F generator can describe.
- different degrees of modulation and thus crest factors of the output signal can be realized.

- the fundamental frequency of the H F generator and the degree of modulation of the output signal are matched to one another such that a suitable, d. H. for a particular application, a sufficiently large crest factor results on the condition that the modulation frequency does not fall below 100 kHz.

- Modulation frequency the fundamental frequency of the generator and the crest factor.
- Modulation frequency adjusted that a predetermined crest factor to be set is achieved. For example, a crest factor for effective
- crest factor can vary depending on the particular use of the surgical device, for example for cutting and / or coagulating tissue or the like H F-Chiric treatment.
- Modulation frequency is equal to or greater than 200 kHz. Accordingly, the value of the fundamental frequency must be greater, in particular significantly greater than 500 kHz. It is particularly advantageous if the fundamental frequency is greater than five times the modulation frequency.
- the fundamental frequency is greater than five times the modulation frequency.

- Modulation signal m modulated.
- the selected modulation form here is a pulse width modulation, which is accomplished by means of the rectangular modulation signal m.
- the rectangular modulation signal m knows a
- the turn-on and turn-off times of the output signal al result in pulse pauses 13 and pulse packets 15, which are separated from one another by the pulse pauses. From the period ⁇ of the
- FIG. 2 shows a pulse width modulated output signal al.
- the crest factor CF of the output signal al of the HF generator 3 shown in FIG. 2 is greater than the crest factor of the one shown in FIG unmodulated output signal a, since the pulse pauses 13 between the
- Pulse packets 15 provide for a reduction of the rms value of the output signal a l.

- the increase of the crest factor CF is shown in the output signal a2 of FIG. 3 achieved in that the duty ratio D is changed while the modulation frequency f M remains constant oduiation> 100 kHz.
- the Fig. 3 makes it clear that the pulse pauses 13 between the pulse packets 15 are greater than in the example according to FIG. 2. This is achieved in that the switch-on time t a is decreased, while the turn-off time t off of the square pulse m
- the Fig. 4 shows yet another example of a modulated output signal a3 of the H F generator 3, which has a comparison with FIGS. 1 to 3 still
- a pulse packet 5 has only one period t of the output signal a3.
- the effective value of the output signal a3 is reduced, so that the crest factor CF is even greater compared with the examples shown in FIGS. 2 and 3.
- Modulation frequency f M oduiation the crest factor to a variety of applications, such as an RF coagulation or RF cutting process is customizable.
- the crest factor can be increased by reducing the duty cycle D of the modulation signal. For this it is necessary that the fundamental frequency and the fundamental frequency
- Modulation frequency are chosen such that crest factors in a sufficiently large range, preferably from 1.5 to 15 by a
- Pulse width modulation are adjustable. This requires a relatively large
- the G enerator and the modulation frequency fModuiation wherein the boundary condition f M oduiation be ⁇ met 100 kHz spacing between the fundamental frequency f, in order to reliably prevent neuromuscular stimulation.
- the fundamental frequency is preferably five times the modulation frequency to meet the above requirements.
- FIG. 5 another embodiment of the invention is shown in which the fundamental frequency f gen erator of the output signal a4 unchanged while increasing the crest factor CF by reducing the modulation frequency fModuiation is generated, unlike in FIG. 2-4 shown variant.
- the period T 2 of the modulation signal of FIG. 5 is greater than the period Ti used in FIG. 2, wherein the periods t of the pulse packets 15 in the embodiments of FIGS. 2 and 5 match.

It is thus seen that increasing the crest factor can also be effected in that the modulation frequency f M is oduiation reduced.
- FIGS. 2 to 5 show that the fundamental frequency of the generator must be increased by a multiple compared with the modulation frequency in order to be able to generate correspondingly large and variable crest factors, in particular in the range of 1.5 to at least 15, for a very wide variety of applications , For example, for a H F surgical instrument cutting operation, it may be sufficient if the output signal has been modulated to have a crest factor of 1.5. For a coagulation process, however, larger crest factors, in particular in the range of about 2.5, should be present. Furthermore, various mixed forms of cutting and
- Coagulation processes by means of an H F-surgery device feasible for the other crest factors, in particular in the range between 1.5 and 2.5 should be present. Furthermore, there are applications, for. In contactless spray coagulation, where crest factors of 15 or even greater are needed to achieve the desired treatment effect.
- the fundamental frequency of the generator is greater than 100 kHz, namely, in particular in a range between 300 to 600 kHz, but that the modulation frequency f M oduiation 100 kHz does not fall below.
- the H F-surgery device 1 Use case of the H F-surgery device 1 is set, then must be adjusted via a suitable modulation method under the condition that the modulation frequency does not fall below 100 kHz. As I said, it is necessary for this that the fundamental frequency of the generator 3, the Modulation frequency exceeds many times. In particular, according to the invention, the fundamental frequencies can be in one or even several digits megahertz range.
- the present invention reliably avoids the occurrence of neuromuscular stimulation by preventing the occurrence of neuromuscular stimulation
- Modulating frequency is at least 100 kHz and therefore is above the limit, from the present scientific evidence no neuromuscular phenomena such. As muscle twitching, more occur.
- the fundamental frequency is much greater than the usual 350 kHz.
- a sufficient distance between the frequency bands of the modulation frequency and the fundamental frequency is created, which allows the generation of a sufficiently large crest factor, which is in particular greater than 15.
