在用低能量Ｈｅ Ｎｅ激光治疗外耳道及中耳部位的炎性疾病或内耳疾病时 ,常采用棉花或自制橡皮塞堵塞外耳道口以固定Ｈｅ Ｎｅ激光光纤 ,使用非常不便。为此 ,我们设计了一种耳塞式激光光纤固定架。1 结构设计 (图 1)参考临床上应用的声阻抗测定仪的耳部连接部分的构造设计。?
When low-energy He Ne lasers are used to treat inflammatory or inner ear diseases in the external auditory canal and middle ear, cotton or homemade rubber stoppers are often used to block the external auditory canal to fix He Ne laser fiber. This is very inconvenient to use. For this purpose, we designed an earbud laser fiber holder. 1 Structural design (Figure 1) Refer to the structural design of the ear connection part of the clinically applied acoustic impedance analyzer. ?
