Multi-channel radio frequency generator for high-frequency thermal treatment

Abstract

A multi-channel radio frequency generator for high-frequency thermal treatment is used in combination with a plurality of electrodes. The multi-channel radio frequency generator includes an oscillator for producing a high-frequency, a waveform modulator part for modulating an waveform of the high-frequency generated by the oscillator, first to third amplifying channels for amplifying the high-frequency outputted from the waveform modulator part to have a root mean square output of 30-200 Watts and then supplying the root mean square output to the electrodes, a channel selection part for allowing a user to select one or more of the first to third amplifying channels, a key part for enabling the user to set a voltage, a current and an impedance for the first to third amplifying channels, and a microcontroller unit for controlling a power, a time and a phase of the high-frequency outputted from each of the first to third amplifying channels.

Description

technical field [0001] The present invention relates to a multi-channel radio frequency generator for high-frequency thermal physiotherapy, in particular to a multi-channel radio frequency generator that can provide high frequency to multiple electrodes for safer and more effective electrocautery treatment of large-area diffuse cancer cells. The generator can also control more than one amplifying channel to treat distant lesions simultaneously. Background technique [0002] When cancer occurs in an organ of the body, such as the liver, the typical treatment methods are non-surgical methods or surgical treatment. Surgery requires wide incisions in the part of the body where the cancerous lesion is located, which can leave scars and require long-term care after surgery. If the cancer recurs in the body organs, another surgical operation has to be done, which not only makes the patient miserable, but also increases the patient's expenses and risks. [0003] For the above reas...

Problems solved by technology

[0005] In fact, since traditional physiotherapy equipment consists of a single RF generator and a single electrode, the ablation area that can be performed by this equipment is too small to ablate a large tumor mass, resulting in prolonged treatment time

Moreover, this traditional physiotherapy equipment cannot be used for the treatment of distant lesions
