一、前言 低强度激光照射对人体的光生物刺激作用已得到越来越广泛的认可,它具有消炎、镇痛、增强免疫力、促进微循环促进组织修复与再生等作用。在临床上,多用于伤口愈合、慢性溃疡、消炎止痛等,有着确切的疗效。 低强度激光照射在治疗人体浅表及其他易照部位疾病时取得了很大成功,但在应用于腔内多种疾病(如呼吸、消化、排泄、生殖等系统的疾病)时,则遇到了很大困难,存在种种问题。首先是需要将激光准确有效地导入腔内病变部位,其次要简便易行,可重复应用,还 I. Introduction Low-intensity laser irradiation on the human body’s photobiological stimuli has been more widely recognized, it has anti-inflammatory, analgesic, enhance immunity and promote the role of microcirculation in tissue repair and regeneration. In clinical, and more for wound healing, chronic ulcers, anti-inflammatory painkillers, has the exact effect. Low-intensity laser irradiation has been very successful in the treatment of superficial and other vulnerable parts of the human body, but encountered many diseases in the cavity (such as respiratory, digestive, excretion, reproductive and other diseases) Very difficult, there are various problems. The first is the need to accurately and accurately lead to the laser cavity lesions, followed by simple and easy, repeatable, but also
