我院在治疗慢性渗出性中耳炎时,常采用CO2激光辅助鼓膜造孔置管术,取得了良好的治疗效果。但当CO2激光照射到鼓膜上时,鼓膜被汽化,生成烟雾,积聚在外耳道内,烟雾挡住视线看不到鼓膜,给顺利进行手术造成一定困难。因此,我们设计制作了一种带有除烟功能的耳镜,把除烟管与耳镜合成 In our hospital in the treatment of chronic exudative otitis media, CO2 laser assisted tympanostomy catheterization, and achieved good therapeutic effect. However, when the CO2 laser irradiation to the tympanic membrane, the tympanic membrane is vaporized, generating smoke, accumulate in the external auditory canal, the smoke block the line of sight can not see the tympanic membrane, to the smooth operation caused some difficulties. Therefore, we designed and manufactured an otoscope with a smoke removal function to synthesize the smoke removal tube and the otoscope
