Title:
LASER TREATMENT DEVICE
Document Type and Number:
Japanese Patent JP2002045371
Kind Code:
A
Abstract:

To provide a laser treatment device with which a noise from a cooling fan is decreased and treatment environment can be improved.

This laser treatment device has a cooling means with a fan to cool a laser oscillator, a thermosensor that detects a temperature of the laser oscillator directly and indirectly, and a fan controlling means that moves the fan at approximately constant low speed in a temperature range until the detected temperature by the thermosensor reaches constant and moves the fan for ventilation at approximatery constant high speed in a temperature range above the fixed value of the detected temperature in the laser treatment device with which a laser beam for treatment is irradiated to a lesion area to be treated.
