Therapeutic head of semiconductor laser therapeutic apparatus

The invention relates to a nasal cavity irradiating therapeutic head of a semiconductor laser therapeutic apparatus, which can reach effectiveness and safety requirements on laser clinical therapies. The nasal cavity irradiating therapeutic head comprises a laser, a heat-stabilized heat conducting device, a packing positioning device, a light guiding and transmitting device, a laser window cover, a housing, a nasal clip device and a power supply lead, wherein the heat-stabilized heat conducting device is designed according to heat balance temperature to control the operating temperature range of the laser, the light guiding and transmitting device is designed according to fiber optical light guide transmission so that the laser is far away from a laser irradiating window, which is beneficial to structural design; meanwhile, a fiber numerical aperture is used for ensuring the guide and the scattering output of scattered semiconductor laser. The housing is made from an insulating material and is an anti-static electromagnetic compatibility design, which prevents electrostatic interference from causing the laser power attenuation and the laser damage. The laser window cover is designed by adopting safe irradiation power density of a light outputting opening and laser scattering irradiation on light spots, the safety control of laser irradiation is provided, and thus the effectiveness of the clinical therapies and the safety of the laser irradiation can be ensured.
