FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4. FIG. In FIG. 3, the circuit portion excluding the power supply portion 11 is a circuit diagram showing the entire configuration of the human body contact sensing portion 60. FIG.

The configuration of the present invention, as shown in Fig. 2 and Fig. 3,

The high frequency pulse generated by the high frequency generating unit 12 is amplified by the high frequency amplifying unit 14 and then outputted from the high frequency output unit 16 by supplying the circuit power from the power supply unit 11, 24 so as to flow a high-frequency current to the human body,

And a human touch sensing unit 60 sensing the electrical contact state between the ceramic body 22 and both electrodes of the plate 24 and outputting the sensed electrical contact state to the controller 18.

As shown in FIGS. 2 to 4, the controller 18 determines whether a predetermined reference voltage is exceeded or not based on the human touch sensing signal transmitted from the human touch sensing unit 60, Frequency output section 16 to cut off the high-frequency output or to lower the voltage.

3, which is an embodiment of the present invention, the human body touch sensing unit 60 is a level corresponding to the current change of the power supply unit 11 that receives the AC power and supplies the power supply current to the entire circuit, A rectifying unit 68 for rectifying the amplified signal of the amplifying unit, and a rectifying unit 70 for rectifying the rectified signal. The rectifying unit 68 rectifies the amplified signal of the amplifying unit, And a digital signal converting unit 74 for converting the voltage level of the smoothed signal to a digital level and applying the smoothed signal to the control unit as a human touch detection signal. In FIG. 3, SH denotes a shunt for inducing a current change in an inductive coil system, OP1 and OP2 are amplifiers, R1 to R5 are resistors, C1 to C3 are capacitors, and D1 to D2 are diodes.

3 shows that the shunt SH at the tip of the input unit of the human body touch sensing unit 60 is provided on the distal end side of the power source unit 11 but may be provided at the rear end side of the power source unit, It is possible to detect the current change for detecting the current.

That is, in the present invention, the human body touch sensing unit 60 includes a high frequency amplifying unit having a large change in current consumption among the entire circuits, and a selected one of a power input line and a power output line of a power supply unit 11 for supplying power to the high frequency output unit And applies a human touch sensing signal to the control unit 18 using a change in current flowing in one place as a base signal.

4, the reference voltage programmed in advance by the controller 18 is divided into a plurality of reference voltages (1V, 2V, and 3V, for example) that are set in advance at different voltage levels The controller 18 is configured to compare the voltage level of the human touch sensing signal input from the human touch sensing unit with the plurality of reference voltages in real time to block the high frequency output. In addition, it is also preferable to perform a real-time control program for repeating the process of gradually stopping the high-frequency output and gradually stopping the high-frequency output and then interrupting the high-frequency output again.

When the human body touch sensing signal is transmitted to the controller, the controller determines the program routine as shown in FIG. 4 and controls the high frequency output level.

The program routine of the control unit shown in FIG. 4 corresponds to one embodiment. In addition, the sequence of the operation procedure described below may be added to the program routine of the software configuration of FIG.

Hereinafter, the operation related to the spark generation suppressing control in the high frequency treatment apparatus of the present invention having the above-described configuration will be described as follows.

The shock noise is generated from the initial point of time when the above-described spark occurs as compared with the normal high-frequency output, and a large current flows due to the energy due to the spark due to the overcurrent in a very short time. The amount of current flowing to the entire circuit shown in Fig. 2, particularly, the high-frequency amplifying section 14 and the high-frequency output section 16 suddenly changes greatly.

This change in current flow is compounded with the characteristic of 'high frequency' that changes the voltage level at a very fast cycle. Therefore, a very high shock voltage that causes sparking between electrode and skin with poor skin contact .

The present invention preliminarily monitors and accumulates various types of waveforms and current changes at the time of occurrence of the above-described spark, stores them in advance as a reference data value in the program of the control unit 18, In the case of using the output of the 'power supply unit', the high frequency in the normal normal operation is outputted as the output of the power supply unit 11, The voltage monitored by the human body touch sensing unit 60 is extracted only by a small voltage value. On the other hand, when a spark occurs, a large current change occurs suddenly. Therefore, (Human touch sensing signal) is represented by a large voltage value.

The present invention monitors such a spark generation mechanism by the current change detection unit 64 of FIG. 3, extracts the spark generation mechanism as a waveform having a waveform as a voltage value, and outputs the extracted voltage waveform as a pulse of one level (+ Converted into a voltage value, smoothed by the smoothing unit 72, converted into a digital value, and sent to the control unit 18, where it is compared with the data value of the base voltage. To do so, the amplification circuits OP1 and OP2 in the current change detection unit 64 and the amplification unit 66 amplify the amplified surveillance signal so that the spark level can be determined, The smoothing unit 72 smoothens the smoothed level to a predetermined level and extracts the smoothed analog value as an analog value. When the digital signal is converted into a digital data value by the digital signal changing unit 74 and is input to the control unit 18, The spark generation level is compared with a reference stored in advance, and the level of the spark is determined as digital logic, and it is notified to the operator through a warning display and a warning sound through the display unit 24 and a separate alarm unit.

The control unit 18 can eliminate the generation of high frequency pulses in the high frequency generating unit 12 or block or prevent the amplification of one or more of the high frequency amplifying unit 14 and the high frequency output unit 16, As a method of lowering the amplification degree, spark generation is blocked.

In this state, the practitioner calibrates the contact between the electrodes (ceramic, plate) and the human body, eliminates the cause of sparks, and then uses the high frequency treatment device normally.

In this case, when the monitoring value inputted in the control unit 18 is monitored in advance and compared with the set value, it is determined that the image is generated at the time of occurrence of spark, the above-described high frequency output is temporarily stopped, It is also possible to perform control such that the high-frequency output is gradually raised to the original level while the high-frequency output is outputted at a level where the high-frequency output disappears.

This operation example is divided into two operation procedure examples and will be described more specifically.

The control unit 18 outputs a high-frequency fundamental signal,

When the high frequency base signal is lowered to a very low level, the voltage value of the high frequency output signal outputted from the high frequency output section after being amplified by the high frequency amplifying section having a certain amplification degree is lowered, and the cause of the spark is remarkably reduced or disappear. At this time, since the value monitored in real time from the human body contact sensing unit 60 is inputted to the control unit 18, even if the condition at the time of the operation is poor, a warning signal is generated through the display unit 24 of FIG. 2 It is possible to eliminate the cause of spark generation without stopping the high frequency operation by turning off the operation of the high frequency treatment device and resetting the operation of the high frequency treatment device. Correct use) can be performed.
