Abstract:
A laser treatment apparatus which is used to treat an affected part of a patient's skin by irradiating a treatment laser beam to the affected part, the apparatus including:a laser irradiation unit provided with a laser irradiation optical system for delivering the laser beam to the affected part; a contact member including a contact face which is adapted to be brought into contact with the affected part; a cooler which cools the contact member via a conducting member; a contact sensor which detects whether the contact face is in a contact state or the contact face is in a non-contact state with respect to the affected part; a first temperature sensor which detects a first temperature of the affected part or the contact member; a second temperature sensor which detects a second temperature of the conducting member; and a temperature controller which controls cooling operations of the cooler based on a result of detection by the second temperature sensor when the contact sensor detects that the contact face is in the non-contact state, and based on a result of detection by the first temperature sensor when the contact sensor detects that the contact face is in the contact state.
