Treatment tool and endoscope system with inductance elements to power treatment device of treatment tool
First Claim
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; and
a first inductance element arranged to the channel, wherein the first inductance element is configured to receive a high-frequency power from a power source to generate an AC magnetic field; and
a treatment tool comprising;
a treatment tool insertion section configured to be movably inserted in the channel of the endoscope;
an electrically powered treatment device attached to the treatment tool insertion section to be moved by the treatment tool insertion section;
a second inductance element arranged to the treatment tool insertion section, wherein the second inductance element is inductively coupled to the first inductance element such that the AC magnetic field induces an electromotive force to generate an induced current in the second inductance element; and
a power converter configured to convert power received by the second inductance element to power used by the electrically powered treatment device to perform a treatment, and to directly or indirectly output the converted power to the treatment device to power the electrically powered treatment device to perform the treatment.
