Definitions
- the invention relates to an electrosurgical instrument comprising at least one display device for displaying at least one status information of a control unit and an adapter for connecting an electrosurgical instrument.
- Electrosurgical instruments have been used for many years in high frequency surgery (RF surgery) to coagulate or even cut biological tissue.
- RF surgery high frequency surgery
- a high-frequency current is passed through the tissue to be treated, so that this changes due to protein coagulation and dehydration.
- the tissue contracts in such a way that the vessels are closed and bleeding is stopped.
- the tissue is completely severable while avoiding heavy bleeding, both with the help of high-frequency current, as well as by mechanical means.
- Electrosurgical procedures can be performed with monopolar and bipolar instruments.
- the current path usually leads from the electrosurgical instrument via the tissue to be treated to a neutral electrode.
- bipolar instruments may be used, which are formed with two mutually electrically isolated sections. The current path in this case extends from a first section of the electrosurgical instrument via the tissue to be treated to a second section of the electrosurgical instrument.
- the electrosurgical instrument should be intuitive to use and should contain all the necessary information be easily available.
- this information includes status information provided, for example, by an RF generator.
- DE 36 27 221 Al shows a handle for an electrosurgical instrument having a power control and an optical power indicator.
- This power indicator on the handle indicates information about the power delivered, such as the presence of high or low voltage.
- a handle for an electrosurgical instrument which is characterized in that the electrode-side end of the handle, a light exit opening is provided, which is fed by a located in the RF generator cold light generator.
- the light source serves to illuminate the surgical field better.
- DE 199 43 792 A1 discloses an electrosurgical instrument in which the handle arranged thereon has a display device which makes it possible to read operation-specific information, for example the operating mode of the electrosurgical instrument.
- an electrosurgical instrument comprising at least one display device for displaying at least one status information of a control unit, wherein the display device is arranged on the electrosurgical instrument and oriented in the distal direction, that the display device in an active state, an operating field of electrosurgical instrument illuminates.
- the display device may be a single light emitting diode or an array or matrix of light emitting diodes. These are preferably active elements which indicate at least one status of a control unit and / or of the HF generator and / or of the electrosurgical instrument itself.
- an active state of the display device may be defined as the state in which the display device is illuminated.
- the active state of the display device preferably correlates with an active state of the electrosurgical instrument in which it is immediately ready for operation, for example a current is present for carrying out a coagulation process.
- the advantage of the present invention is therefore that the display is not only used to provide the user of the device or the electrosurgical instrument information about its status, but at the same time fulfills a lighting function, which in the actual intervention by means of the electrosurgical Instrument is helpful.
- the electrosurgical instrument includes a handle, wherein the at least one display device is disposed at a distal end of the handle. That is, the display device is arranged so that it radiates in the direction of the actual tool head of the electrosurgical instrument and thus illuminates the area where the electrosurgical instrument is to be used.
- the electrosurgical instrument described has particular advantages in a hand-held instrument.
- the display device is designed to emit colored light. The different hues can either be used to indicate different status information or to identify different electrosurgical instruments.
- the hue of the display device of the electrosurgical instrument could correspond to a hue on the RF generator to indicate that, among a variety of electrosurgical instruments, the present one is active, or that an RF voltage is applied to the present electrosurgical instrument.
- the at least one status information indicates a concern of a voltage on the electrosurgical instrument and / or a power indication and / or an operation mode of the control unit.
- a voltage on the electrosurgical instrument and / or a power indication and / or an operation mode of the control unit.
- it makes sense to indicate the presence of a voltage when a distinction has to be made between a plurality of instruments which are partly or all connected to the same HF generator. Even if only a single electrosurgical instrument is used, it may be useful to particularly mark the active state of the electrosurgical instrument to avoid erroneous operation.
- the color indication can visualize a current intensity and / or a voltage and / or a frequency and / or a particular frequency pattern. For example, it has been found that coagulation of tissue requires a different voltage pattern (first mode of operation) than the voltage pattern used to cut through a corresponding tissue (second mode of operation). The color coding could therefore serve to distinguish the modes of operation.
- the display device is coupled into a supply voltage of the electrosurgical instrument.
- the display device can thus be partially or fully fed by the supply voltage, which is present for example for a coagulation process on the electrosurgical instrument.
- the object is achieved by an adapter for connecting an electrosurgical instrument, wherein the adapter comprises:
- At least one supply line for providing a supply voltage for the electrosurgical instrument; and a display device connected to the at least one supply line.
- the adapter to which the corresponding electrosurgical instrument is connected comprises a display device which identifies the corresponding instrument or adapter.
- the indicator on the adapter may also serve to provide status information to the user of the electrosurgical instrument.
- the adapter may be, for example, the end of a supply cable of the electrosurgical instrument, the adapter preferably comprising a plurality of terminals for connecting the instrument.
- the adapter may include controls.
- the at least one supply line is designed to provide an HF voltage. That is, the adapter provides the supply voltage for the electrosurgical instrument and is preferably electrically connected to the RF generator.
- the display device is designed to display an applied voltage, in particular an HF voltage.
- the status information displayed by the display device may indicate whether the connected electrosurgical instrument or adapter is active, i. is supplied with a corresponding voltage.
