激光因其特有的组织效应可用于手术中切割与止血，也可用于生物组织刺激，产生特定的物理治疗效应。妇科手术常用的激光能量有两种方式：钬激光用于宫腔镜生理盐水膨宫下宫腔病损切割与消融、CO2激光腹腔镜下病灶切割与止血。激光具有切割定位准确、垂直损伤浅、侧损伤小、组织术后恢复快等优点，可广泛应用于妇科盆腔手术。

Abstract:Laser can be used for incision and hemostasis because of its typical organizational effect,and also can be used for biotic tissues stimulus with specified physiotherapy effect. There are two kinds of energy of laser frequently used in gynecological operation: holmium laser can be used for lesion resection and ablation under the physiological saline hysteroscopes, and carbon dioxide laser can be used for incision and hemostasis during laparoscopic operations.Since the laser has advantages of pinpoint, shallow vertical injuries and narrow side injuries, it can generally be used in gynecological pelvic operations.
