PROBLEM TO BE SOLVED: To properly apply laser beam irradiation while allowing a tip part of a hand piece to abut in a desired state. SOLUTION: In a laser treatment device having a hand piece having a scanning optical system for scanning a laser beam and performing a treatment by irradiating the laser beam to a treating part, a scanning pattern shape of a smaller area than the inside of a scanning area by the scanning optical system is stored, an irradiating position of the stored scanning pattern shape is variably set, and the scanning optical system is controlled in driving on the basis of this setting information. |
