1. An endoscope system comprising:

  • an endoscope comprising;

    an endoscope insertion section comprising a portion that is flexible, wherein the endoscope defines a channel having a distal opening in the endoscope insertion section;

    a first transmission electrode arranged to the channel, wherein the first transmission electrode is electrically connected to a power source configured to output a high-frequency power; and

    a second transmission electrode arranged to the channel, wherein the second transmission electrode is electrically connected to the power source; and

    a treatment tool comprising;

    a treatment tool insertion section configured to be movably inserted in the channel of the endoscope;

    a first reception electrode arranged to the treatment tool insertion section, wherein the first reception electrode is spaced apart from the first transmission electrode to form a first capacitor;

    a second reception electrode arranged to the treatment tool insertion section, wherein the second reception electrode is spaced apart from the second transmission electrode to form a second capacitor; and

    an electrically powered treatment device attached to the treatment tool insertion section to be moved by the treatment tool insertion section, wherein the electrically powered treatment device is electrically connected to the first reception electrode and the second reception electrode to be powered to perform a treatment on a subject,wherein the endoscope further comprises;

    a variable inductor, wherein the variable inductor, the first capacitor, and the second capacitor are electrically connected to form a resonant circuit; and

    a controller configured to control the variable inductor to adjust a resonant frequency to coincide with a frequency of the high-frequency power.
