Wireless electromagnetic thermotherapy apparatus

A wireless electromagnetic thermotherapy apparatus configured to apply a magnetic field on a needle which is disposed on a body part to be treated for actuating heat generation by the needle, said wireless electromagnetic thermotherapy device comprising:

• an excitation device including a magnetic field output unit configured to produce the magnetic field for actuating the needle to heat up to a target temperature, and an excitation controller configured to adjust an intensity of the magnetic field produced by the magnetic field output unit;
• and
• a detector device to be coupled to the needle, and including
• a sensor unit configured to measure an actual temperature of the needle to result in a measured temperature value,
• a wireless charging unit configured to generate electrical energy in response to receipt of the magnetic field, and to store the electrical energy thus generated, and
• a wireless transmitter electrically connected to said sensor unit for obtaining the measured temperature value from said sensor unit, electrically connected to said wireless charging unit for being powered by the electrical energy generated thereby, and configured to transmit the measured temperature value to said excitation controller of said excitation device through wireless communication, so as to enable said excitation controller to make a comparison between the measured temperature value and a value of the target temperature and to adjust the intensity of the magnetic field, produced by said magnetic field output unit, based on a result of the comparison.
