Patent number: 6817997Abstract: A laser treatment apparatus for performing treatment on a treatment part of a skin by irradiating the part with a laser beam for treatment is disclosed. The apparatus includes: a window having an optical property of transmitting the treatment beam, the window being brought into contact with the skin for laser irradiation; a window cooling unit; a contact-state detector which detects a contact state of the window with the skin; and a controller which changes a cooling control temperature of the cooling unit from a predetermined first temperature which is previously set higher than 0° C. to a predetermined second temperature lower than the first temperature when the contact-state detector detects that the window is in contact with the skin.Type: GrantFiled: February 25, 2002Date of Patent: November 16, 2004Assignee: Nidek Co., Ltd.Inventors: Takahiro Furuno, Wataru Niwa

Patent number: 6733492Abstract: A laser treatment apparatus which is used to treat an affected part of a patient by irradiating a treatment laser beam to the affected part is disclosed. The apparatus includes 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 brought into contact with at least one of the affected part and a periphery thereof; a cooler which cools down at least the contact face of the contact member; a sensor which detects at least one of a temperature of a periphery of the contact face made contact with the affected part, a temperature of a predetermined portion of at least one of the contact member and the cooler, a contact state of the contact face with respect to the affected part, and a relative substantially horizontal movement of the contact member with respect to the affected part; and an irradiation controller which controls laser irradiation based on a result of detection by the sensor.Type: GrantFiled: February 1, 2001Date of Patent: May 11, 2004Assignee: Nidek Co., Ltd.Inventors: Yasuo Ota, Hideo Mukai, Yohei Kamihagi, Wataru Niwa

Patent number: 6621838Abstract: A laser treatment apparatus for performing treatments on an affected part by irradiating the affected part with a laser beam for treatment is disclosed. This apparatus includes a laser oscillator, a cooling unit including a fan which cools the laser oscillator, a temperature sensor which directly or indirectly detects a temperature of the laser oscillator, and a control unit which drives the fan at roughly constant low speed when a detected temperature by the temperature sensor is below a predetermined reference value and at roughly constant high speed when the detected temperature is the predetermined reference value or more.Type: GrantFiled: July 25, 2001Date of Patent: September 16, 2003Assignee: Nidek Co., Ltd.Inventors: Yasuyuki Naito, Wataru Niwa
