Endoscope having power transmission electrode and treatment tool having power reception electrode, and endoscope system
First Claim
1. An endoscope system comprising:
- an endoscope comprising;
an endoscope insertion section configured to be inserted into a subject, wherein the endoscope insertion section defines a channel having a distal opening; and
a power transmission electrode arranged to the endoscope insertion section, wherein the power transmission electrode is electrically connected to a power source configured to output a high-frequency power; and
a treatment tool comprising;
an electrically powered treatment device;
a treatment tool insertion section attached to the electrically powered treatment device, wherein the treatment tool insertion section is configured to be arranged in the channel of the endoscope; and
a power reception electrode arranged to the treatment tool insertion section,wherein the power reception electrode is separated from the power transmission electrode to form a first capacitor to transfer power from the power source through an electric field between the power transmission electrode and the power reception electrode to power the electrically powered treatment device,wherein the endoscope further comprises an inductor,wherein the inductor and the first capacitor are electrically connected to form a resonant circuit, andwherein the resonant circuit has a resonant frequency that coincides with a frequency of the high-frequency power.
