FRONT SURFACE COOLING METHOD AT THE TIME OF LASER IRRADIATION

摘要

PROBLEM TO BE SOLVED: To obtain an efficient and easy front surface cooling method at the time of a laser irradiation. SOLUTION: In a method for destroying a specified subcutaneous tissue and medically treating it by the irradiation of a laser beam, a mist-state liquid is sprayed to an epidermis above the subcutaneous tissue and also gas is blown so that the vaporization of the liquid is promoted and the heat of the epidermis is taken away by the heat of vaporization. Then, the epidermis is cooled.
