Problems solved by technology
Although this method can meet the requirements of multi-pole output, it requires the consistency of the sinusoidal signals output by each channel, and has high requirements for the phase of each channel. At the same time, due to the strong coupling between each channel, Therefore, the control algorithm between the various outputs will be more complicated, and the radiofrequency ablation system implemented in this way has not been popularized in multi-polar applications in pain treatment

Embodiment 1
[0048] The multi-pole RF output circuit of the single power source RF generating circuit such as figure 2 As shown, the circuit is composed of a single power source radio frequency generation circuit, a switch control module, a data detection module for each channel, a filter module for each channel, and an output terminal for each channel. The realization of its function has the following two steps:
[0049] Step S1: The single power source radio frequency generating circuit outputs one radio frequency signal.
[0050] Step S2: The radio frequency signal is input to the switch control module. Under the action of the switch control module, multiple radio frequency signals are output by time-sharing switching. Each radio frequency signal of the multi-channel radio frequency signal has undergone data detection, and the detection result is fed back For a single power source RF generating circuit.
[0051] The specific implementation process of time-sharing switching is as foll...

The present invention discloses a multipole radio frequency output control method based on a single power source radio frequency generating circuit and belongs to the technical field of radio frequency ablation. The multipole radio frequency output control method comprises the following steps: 1, a single power source radio frequency generating circuit outputs a path of radio frequency signals; and 2, the radio frequency signals are input into a switch control module, under the action of the switch control module, multiple paths of radio frequency signals are output in a time-sharing switchingmode, each path of the radio frequency signal of the multiple paths of the radio frequency signals is subjected to data detection, and a detection result is fed back to the single power source radiofrequency generating circuit. The single radio frequency power source is adopted to realize output of the multiple paths of the radio frequency signals by the method, and besides, each path of the radio frequency signal is independently output without mutual interference.
Description
technical field [0001] The invention relates to a multi-pole radio frequency output control method in the technical field of radio frequency ablation, in particular to a multi-pole radio frequency output control method based on a single power source radio frequency generation circuit. Background technique [0002] In the existing minimally invasive surgery, radio frequency technology has been widely used in the treatment of many diseases. The radio frequency technology can generate a sine wave with a frequency between 300Khz-1000Khz, and the generated radio frequency energy passes through the radio frequency catheter Or the radiofrequency electrode acts on the lesion that needs to be treated, so that it can achieve the effect of blocking or conditioning, and then achieve the effect of treatment. [0003] In the field of pain treatment, radiofrequency technology has long been the first choice for minimally invasive surgery. Existing radiofrequency ablation systems for pain t...
