Abstract

In an electrosurgical power supply apparatus combined with an electronic endoscope system, there is provided an electrosurgical signal generator. The electrosurgical signal generator includes PROM for previously storing data representative of electrosurgical high-frequency currents. In response to a selection signal of an electrosurgical operation mode, the data is read out from PROM to produce the electrosurgical high-frequency current corresponding to the selected electrosurgical operation mode.

Claims

1. An electrosurgical power supply apparatus comprising:

means for selecting an electrosurgical operation mode to produce a mode selection signal;

source means for producing an electrosurgical high-frequency signal in response to the mode selection signal; and

,

means for producing a color signal indicative of the electrosurgical operation mode selected by the mode selecting means in response to the mode selection signal, whereby the selected electrosurgical operation mode is represented in a predetermined color, wherein said color signal producing means includes at least;

character generator means for generating character data indicative of the selected electrosurgical operation mode selected by said selecting means; and

color table means for previously storing therein color data preselected based upon the electrosurgical operation mode, and for outputting both the character data indicative of the selected electrosurgical operation mode and the color data read therefrom in accordance with the character data indicative of the selected electrosurgical operation mode, whereby a title of the selected electrosurgical operation mode is displayed in a predetermined color defined by the color data.

2. An electrosurgical power supply apparatus as claimed in claim 1, wherein said color signal producing means further includes:

a television synchronization signal generator for generating both a horizontal synchronization signal and a vertical synchronization signal so as to display the title of the selected electrosurgical operation mode on a television monitor.

3. An electrosurgical power supply apparatus as claimed in claim 1, wherein said color signal producing means produces a plurality of color signals representative of pictorial forms with preselected colors in accordance with the selected mode signals.

4. An electrosurgical power supply apparatus as claimed in claim 1, wherein said selecting means is constructed of a plurality of switches.

5. An electrosurgical power supply apparatus in combination with and for supplying power to an electronic endoscope system including at least image sensor means for producing an image signal of an interior of an internal organ under medical examination;

image signal processing means for processing the image signal to obtain an endoscopic image signal; and

a color television monitor connected with said image signal processing means for displaying an endoscopic image of an object in response to the endoscopic image signal, comprising;

means for selecting an electrosurgical operation mode to produce a mode selection signal;

source means for producing an electrosurgical high-frequency signal in response to the mode selection signal;

means for producing a color signal representative of the electrosurgical operation mode selected by the mode selecting means in response to the mode selection signal and for supplying the color signal to the color television monitor;

whereby the selected electrosurgical operation mode is displayed on the television monitor in a predetermined color together with the endoscopic image of the object.

6. An electrosurgical power supply apparatus combined with an electronic endoscope system as claimed in claim 5, wherein said color signal producing means includes at least:

character generator means for generating character data indicative of a title of the selected electrosurgical operation mode;

color table means for previously storing therein color data preselected based upon the selected electrosurgical operation modes, and for outputting both the character data indicative of the selected electrosurgical operation mode and the color data read therefrom in accordance with the character data indicative of the selected electrosurgical operation mode, whereby a title of the selected electrosurgical operation mode is displayed in a predetermined color defined by the color data on the color television monitor.

7. An electrosurgical power supply apparatus combined with an electronic endoscope system as claimed in claim 6, wherein said color signal producing means further includes:

a television synchronization signal generator for generating both a horizontal synchronization signal and a vertical synchronization signal in order to display title of the selected electrosurgical operation mode on the color television monitor.

8. An electrosurgical power supply apparatus in combination with and for supplying electric power to an electronic endoscope system including at least image sensor means for producing an image signal of an interior of a subject under medical examination;

image signal processing means for processing the image signal to obtain an endoscopic image signal; and

a color television monitor connected to said image signal processing means for displaying an endoscopic image of the interior of the subject in response to the endoscopic image signal, comprising;

means for selecting an electrosurgical operation mode to produce a mode selection signal;

source means for producing an electrosurgical high-frequency signal in response to the mode selection signal;

means for producing a visual signal representative of the electrosurgical operation mode selected by the mode selecting means in response to the mode selection signal and for supplying the visual signal to the color television monitor;

whereby the selected electrosurgical operation mode is displayed on the television monitor in a predetermined color together with the endoscopic image of the subject.

9. An electrosurgical power supply apparatus as claimed in claim 8 wherein said operational modes include coagulation, cutting and blend.

10. An electrosurgical power supply apparatus as claimed in claim 8 wherein said visual signal is a color signal.

11. An electrosurgical power supply apparatus as claimed in claim 8 wherein said operational modes include coagulation, cutting and blend.
