激光免疫疗法是目前治疗风湿病新兴的医疗技术。根据治疗机理和临床需要 ,采用微机分别控制CO2 激光器和开关电源使激光输出功率、照射时间连续可调 ,整个治疗过程一次完成。精心设计的光学系统减少了激光聚焦斑点 ,避免了组织的损伤 Laser immunotherapy is the emerging medical technology for the treatment of rheumatism. According to the treatment mechanism and clinical needs, the microcomputer controls the CO2 laser and the switching power supply respectively to make the laser output power and the irradiation time continuously adjustable, and the whole treatment process is completed at one time. Well-designed optics reduce laser spotting and avoid tissue damage
