Abstract：
 The invention is related to embedding type technical area of medical treatment instrument. Characters are that the instrument includes receiving coil embedded inside human body, charging control circuit, rechargeable battery, and transmitter coil located outside human body, and drive circuit for transmitter coil. The transmitter coil outside human body is in larger size in flat shape. Receiving coil inside human body is in smaller size in column form. Both coils contain magnetic core. Electromagnetic coupling mode parallel to axes is adopted in the invention. Under excitation of drive circuit, the transmitter coil transmits electromagnetic energy. Obtaining energy, the receiving coil charges the rechargeable battery through the charging control circuit. Through skin, even case made from titanium, the method is capable of charging medical instrument. Features are: good positioning tolerance easy of adjustment, simple and reliable charging procedure.
