Definitions
- the invention relates to an electrosurgical hand instrument having a handpiece, which has a connection side and a treatment side, and having a connection plug, which is electrically connected to the connection side of the handpiece and electrically connectable with an intended for operating the instrument RF generator.
- US 201 1/0071520 discloses an electrosurgical hand instrument in the handpiece of which is integrated a microprocessor-based transceiver unit for bi-directional communication with an RF generator.
- an RF generator with a universal jack which includes an instrument recognition.
- the instrument recognition is used to set parameters for a hand instrument in the RF generator.
- the parameters are stored in a non-volatile memory (EEPROM) in the connector of the hand instrument during manufacture and read out when connecting the instrument to the RF generator via the connector and set.
- EEPROM non-volatile memory
- the object is achieved in that the electrosurgical instrument has a control unit which is designed to actively control the voltage shape of an RF energy output at the treatment side of the handpiece.
- the invention has recognized as disadvantageous that newly developed electrosurgical hand instruments may have a wider range of functions than existing RF generators and thereby often are not fully usable. This is because the incorporation of new functions into an RF generator - which would be required to operate a newly developed electrosurgical hand instrument - typically requires a costly hardware revision of the RF generator, the development of hand instrument RF generators therefore lags.
- the invention also includes the recognition that hand instruments or applicators for HF generators exist as "passive" instruments, for example corresponding bipolar hand instrument connectors having two terminals are provided and the voltage is applied to the electrodes in two cables.
- active signal adaptation or switching is not performed in the hand instrument, but is output functionally by the HF generator, meaning that the functions are applied to the respective generator socket.
- the present invention provides the basis for the fact that the extension of an RF surgical system (hand instrument and RF generator) to new RF applications in the future additionally or exclusively - apart from a relatively inexpensive software update in the RF generator - can be done on the hardware side in the hand instrument , A costly hardware change or new development of RF generators is not mandatory. It is also conceivable that the development of special small series instruments or devices with additional functions (eg motors, valves, pumps, etc.) can be made more cost-effective because the functions do not have to be implemented in the HF generator on the hardware side.
- the control unit is designed to modify an RF energy supplied by the RF generator, if necessary, and to output this changed RF energy to the treatment side of the handset.
- such a changed RF energy can be output to the treatment side of the handset, without necessarily having to resort to a function in the RF generator.
- Modification may, in particular, also be understood to mean modulating an HF energy, for example impressing a voltage form.
- a voltage form should be understood as meaning both the amplitude and the frequency of an HF energy.
- the RF generator is configured to deliver a first number of voltage waveforms, such as a voltage waveform for cutting and a voltage waveform for coagulation, to the instrument, then the electrosurgical instrument is capable of being activated by the active control device, such as a third one, not the Generator supplied voltage form to supplement, for example, a voltage waveform for a plasma blend mode.
- the instrument has a return channel to the HF generator and the control unit is designed to control a voltage form of the RF energy delivered by the HF generator to the instrument via the return channel. That is, signal conditioning, ie modifying and / or modulating RF energy into a desired voltage form, does not necessarily occur within the instrument itself. Rather, in the present development, the control unit arranged in the instrument acts in the sense of an "external control unit" for an HF generator.
- control unit In order to operate the instrument on a wide range of different RF generators, it has proven to be advantageous if the control unit is designed to switch between different RF voltage modes delivered by the RF generator to the instrument. Advantageously, it is thus possible to fall back on predefined RF voltage modes or voltage forms in the HF generator. In this case, it is possible, for example, to switch between a cutting mode and a coagulation mode.
- a manual switch is also typically provided on an electrosurgical instrument via which a manual input can be made so as to switch between different RF voltage modes output by the HF generator.
- the advantage of an active control unit now results from the fact that switching regimes are possible by this control unit, which can not be realized by a manual operation of a manual switch, for example. For example, a Switching between a cutting mode and a coagulation mode with a frequency of 50 Hz.
- the return channel is provided via a modulated manual switch signal.
- a modulated manual switch signal for example, by changing the switching frequency between 200 and 300 Hz, for example, by an amplitude or a frequency modulation of the switching signal.
- the control unit may be synchronized via a modulated manual switch signal with a change in the voltage form of the RF energy emitted by the RF generator.
- control unit can be controlled via a modulated manual switch signal output by the HF generator.
- a modulated manual switch signal output by the HF generator is useful, for example, if the HF generator is equipped with an advanced switching functionality by a software update that is relatively easy to implement, but the HF generator does not have its own driver stage for outputting the extended functionality.
- This driver stage can now also be "outsourced" to the control unit in order to output a voltage form on the treatment side of the handpiece, which can not be readily provided by the HF generator.
- control unit via a manual switch line with energy.
- control unit can also be supplied with energy via a battery provided in the instrument.
- control unit has a microcontroller which is designed to output an instrument identifier of the electrosurgical instrument to an HF generator and / or the microcontroller is designed to emulate an instrument identifier of a passive nonvolatile memory in relation to an HF generator ,
- a microcontroller included in the control unit may first record the protocol of a emulate passive, non-volatile memory (EPROM) and thus register the instrument to an RF generator.
- EPROM emulate passive, non-volatile memory
- control unit can have a microcontroller or a similar programmable component.
- control unit itself can be designed as a microcontroller.
- control unit has a power electronics and / or driver stage, which is suitable for imparting a voltage form to an HF energy.
- control unit In order to facilitate the handling of the electrosurgical instrument during an operation, it has proven to be advantageous to arrange the control unit in the connector. Alternatively or additionally, the control unit may be arranged in the hand part itself.
- the connector plug can be designed as a universal plug.
- the control unit is designed to control treatment electrodes encompassed by the handpiece. If the electrosurgical instrument is, for example, a bipolar instrument, then the control unit is advantageously designed to operate the treatment electrodes bipolar with an HF energy or HF voltage form.
- control unit is formed, an electromechanical functional element, preferably a motor, valves, pump, or the like. head for. Since such electromechanical functional elements are typically provided in special small-series instruments for which no new development of a HF generator is customary, the above-mentioned advantage of the possible dispensation results in a cost-intensive hardware change of the HF generator accordingly.
- an electrosurgical unit which has a prescribed electrosurgical instrument and an RF generator, wherein the electrosurgical instrument with the RF generator is connected bar.
- the electrosurgical unit can be developed according to the further developments described with reference to the electrosurgical instrument. The advantages described apply accordingly. The different advantageous developments can be combined with each other. The invention will now be explained in more detail with reference to embodiments. Shown are in:
- Fig. 1 a is a schematic representation of an exemplary embodiment of an electrosurgical instrument according to the invention, which is connected to an RF generator;
- Fig. 1 b a modulated manual switch signal
- FIG. 2 is a schematic representation of another exemplary embodiment of an electrosurgical instrument according to the invention and of an HF generator.
- An RF generator 200 in FIG. 1 a has a device connection 230 for connecting an electrosurgical instrument 100, wherein an RF energy from the HF generator 200 can be transmitted to the electrosurgical instrument 100 via the device connection 230.
- the electrosurgical instrument 100 has a handpiece 10, which has a connection side A and a treatment side B.
- electrosurgical treatment electrodes may be arranged on the treatment side B of the handpiece 10.
- the electrosurgical instrument 100 further has a connector 30, which in the present case is electrically connected to the HF generator 200, wherein the connector 30 and the handle 10 are in turn electrically connected via a connecting line 31.
- the electrosurgical instrument 100 has a control unit 20, which is designed to actively control the voltage shape of an RF energy output at the treatment side B of the handpiece 10. As can be seen from FIG. 1, the control unit 20 is arranged in the handpiece 10 itself.
- the instrument 100 has a return channel to the HF generator 200, and the control unit 20 is designed to control a voltage form of the RF energy specified by the HF generator 200 to the instrument 100 via the return channel.
- the return channel is provided via a modulated manual switch signal.
- the manual switch signal like the RF energy itself, is transmitted via the connecting line 31.
- Fig. 1 b) shows such a modulated (frequency-modulated) manual switch signal with a modulation frequency of 250 Hz.
- the control unit 20 is synchronized via an over the modulated manual switch signal with a change in the voltage form of the output from the RF generator 200 RF energy.
- the control unit 20 has a decoder unit (not shown) for demodulating the modulated manual switch signal.
- FIG. 1 Another exemplary embodiment is shown in FIG.
- the RF generator 200 which corresponds to the RF generator of FIG. 1, has a device connector 230 for delivering RF energy to the electrosurgical instrument 100.
- the control unit 20 is arranged in the connection plug 30 of the electro-surgical instrument 100.
- the control unit 20 has a microcontroller 21, which is designed to output an instrument identifier of the electrosurgical instrument 100 to the HF generator 200.
- the microcontroller 21 is designed to emulate an instrument identifier of a passive nonvolatile memory in relation to the HF generator 200.
- the control unit 20 with its microcontroller 21 assumes the extended functionality of the instrument 100, that is, for example, the output of a voltage form on the treatment side B of the handset 10, which can not be provided directly by the RF generator 200.
- microcontroller 21 comprised by controller 20 initially emulates the protocol of a passive, non-volatile memory used in a conventional electrosurgical instrument (not shown).
- the HF generator 200 provided with a software update establishes a communicative connection with the instrument 100 via the return channel realized via the connection line 31, as a result of which an extended functionality of the instrument 100 can be achieved via its control unit 20.
