PURPOSE:To reduce the burden of both an operator and a patient caused by long-time laser radiation, by laying an apparatus for radiating laser in a body an by transmitting power from an external power supply through a wireless transmitting means. CONSTITUTION:An internal device 1 of a laserthermia apparatus for the interior body has a laser generator 6, which includes a semiconductor laser 4 and a laser driving circuit 5, in a case 3 thereof. A power receiver which has an induction coil 7 connecting to the driving circuit 5, is provided around the case 3. The internal device 1 is fixed to a certain position by thrusting needles 8 provided on one edge of the device 1 into a wall 10 of an internal cavity 9. An induction coil 12 provided in a case 11 of an external device 2 is connected to an AC power 13 to form an external power supply 14. The internal device 1 and the external device 2 are placed facing each other to constitute a wireless power transmitting means using electromagnetic induction. When power is supplied to the laser generator 6, the semiconducting laser 4 generates laser rays to a lesion 20 for treatment. |
