Surgical lasers - Principle

Different types of laser are used depending on the nature of the treatment and the tissue to be treated:

  • Continuous CO2, Nd:YAG or diode lasers thanks to thermal effects (photo-coagulation, photo-thermolysis, ...)
  • Pulsed lasers leading to mechanical effect (Photo-ablation)

Wavelength in the range from visible to Infra-Red, continuous power reaching few ten's Watt.

Surgical lasers - Applications

  • Neuro-surgical : Treatment of meningeal tumors
    • Photochemotherapy
    • Fluorescence imaging
    • Photo-ablative lasers
  • Phlebology : Treatment of varicose veins
  • Dermatology : Laser treatment (photo-coagulation or selective photo-thermolysis)
    • Vascular skin lesions (angiomas, érythrocouperose)
    • Pigmented spots, acne
    • Tattoo removal
    • Epilation
  • Gastroenterology : 
    • Treatment of hemangiomas or tumors by photo-coagulation
    • Destruction of kidney stones (pulsed lasers)
  • Gynecology :
    • Treatment of cervical cancers (CO2 laser)
  • Pneumology :
    • Treatment of fibrous strenosis, benign tumors and cancers by endoscopic lasers (Nd:YAG, KTP)
