Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a high frequency electric scalpel device, and particularly to a high frequency electric scalpel device whose output is controlled by a CPU circuit.

BACKGROUND OF THE INVENTION High frequency electrocautery devices are controlled by a CPU and configured to generate cutting, coagulation and blending outputs at appropriate output levels.

[Problems to be Solved by the Invention] In conventional electric scalpel devices, when the power is turned on, an oscillator independent of the CPU starts oscillating before the CPU starts up, so a reset signal necessary for starting up the CPU is required. may be disturbed by the oscillation signal and may not rise normally, which may impede normal operation. For this reason, there is a possibility that the electric scalpel device may malfunction and be dangerous.

Therefore, an object of the present invention is to provide a highly safe high-frequency electric scalpel device in which the CPU can be started up normally.

[Means and effects for solving the problem] According to the present invention, a CPU circuit for controlling the output of a component wave;
a first reset circuit that oscillates independently from the U circuit and outputs a high-frequency signal for high-frequency therapy; a first reset circuit that resets the CPU circuit; and a reset circuit that resets the oscillation circuit after a predetermined time delay from the reset of the CPU circuit. A high frequency electric scalpel device is provided which includes a second reset circuit.

Since the oscillator is reset a predetermined time after the CPU is reset by the first reset circuit, the reset signal of the CPU is not disturbed.

[Embodiment] At J in FIG. 1, the AC power supply 11 is connected to the first and second reset circuits 13 and 14 via the DC converter circuit 12. The first reset circuit 13 outputs a reset signal with a delay time of 401O3 from the output of the DC conversion circuit 12 when the power is turned on. Similarly, the second reset circuit 14 is 100n
s+7) Output a reset signal with a delay time. The output terminals of the first and second reset circuits 13 and 14 are CP
Coupled to U 15 and oscillator 16.

A panel input section 17 is connected to the input side of cpu is.
The display section 18 and the output i1i! are displayed on the output side. I control 81S19 is connected. The output control i[1s19 receives the oscillation output from the oscillator 16 and outputs an incision time signal, a coagulation signal, or a blend signal according to the control signal c p u +s. The output terminal of the output control section 19 is increased) the partition section 20
It is connected to the output transformer 21 via. This output transformer 21 is connected to patient electrodes and the like.

According to the above-described high-frequency electric scalpel device, when the power supply 11 is turned on and the power supply voltage reaches a specified voltage, the CPU reset circuit 13 and the oscillator reset circuit 14 are activated in response to the output of the DC conversion circuit 12. As shown in FIG. 2, the CP reset circuit 13 starts, for example, from the time when the power supply voltage stabilizes.
After the delay time of 401IIS, the reset signal is
Output to J15. The CPU 15 is reset in response to this reset signal and starts a rising operation.

At this time, since the reset signal is not input to the oscillator 16, the oscillator 16 is in a non-oscillating state.
When p u 15 rises, it rises smoothly without being affected by the oscillation output of the oscillator 16.

The oscillator reset circuit 14 outputs a reset signal to the oscillator 16 when the CP IJ 15 has completely risen, for example, after 100 m5 has passed since the power supply voltage stabilized. The oscillator 1G outputs a high frequency signal in response to the reset signal. The high frequency signal is outputted by the output control section 19.
The signal is modulated into a cutting signal, a coagulation signal, or a blend signal by a control signal from the u is, and is input to the amplification/counterfeiting section 20 . Note that the type of signal can be set using the panel input section 17, and the display section 18 can display various data.

The amplified signal output from the amplifying section 20 is outputted from the output transformer 21.
It is output as a high-frequency current through the , and is used for treatments such as incision and coagulation.

[Effect 1] As mentioned above, CPtJ is reset first, and when the CPU has completely started up, a circuit that operates independently of the CPU, such as an oscillator, is activated, so that the CPU can eliminate signal components generated from other circuits. There will be no malfunction due to this. Therefore, high frequency treatment can be performed safely.
