Abstract: A treatment instrument includes a power receiver and a treatment section configured to be driven by power received by the power receiver. The power receiver includes a first solenoid-shaped power receiving coil and a second solenoid-shaped power receiving coil having a winding direction opposite to a winding direction of the first power receiving coil. The first power receiving coil and the second power receiving coil have the same length and the same number of turns, and are arranged concentrically. The first power receiving coil and the second power receiving coil are electrically connected to a treatment section so that a direction in which a current flows through the first power receiving coil is opposite to a direction in which a current flows through the second power receiving coil.

Abstract: A medical power supply system includes: a medical device including an elongated insertion section, a power receiving unit including a power receiving member and movable relative to the insertion section in a longitudinal direction of the insertion section, and a biasing unit biasing the power receiving unit toward a distal end side of the insertion section; and a guide unit including a power transmitting unit including a power transmitting member, the insertion section being inserted into the guide unit. When the insertion section is inserted into the guide unit to a predetermined amount, the power receiving unit comes in contact with the power transmitting unit with being biased by the biasing unit, and the power transmitting member and the power receiving member face each other in an axial direction of the insertion section and have a positional relation in which wireless power transmission is possible.
