众所周知，对分泌性中耳炎或其它原因引发的鼓室积液等患者要进行鼓膜置管手术，以使鼓膜内、外连通，以实现除液、通气的目的，现在鼓膜置管一般采用硅胶制成的哑铃型斜口通气管或T型通气管，治疗时，通气管经托架由鼓膜通气管置入器送入鼓室，现有的鼓膜通气管置入器设有“Z"套管，套管内设有推杆，套管后端设有固定柄，推杆后端设有推柄，使用时，将通气管经托架托在套管前端并置入鼓室处，经固定柄固定好套管后推动推柄，推杆在套管内向前移动，将通气管送入钻好的鼓膜通孔内，这种鼓膜通气管置入器的不足是操作者的视线差、套管固定效果差，这些都直接影响通气管置入的准确性和治疗效果。As we all know, patients with tympanic effusion caused by secretory otitis media or other reasons need to undergo tympanic membrane tube surgery to connect the inside and outside of the tympanic membrane to achieve the purpose of fluid removal and ventilation. Now the tympanic membrane tube is generally made of silica gel. Dumbbell-shaped slanted ventilator or T-shaped ventilator. During treatment, the ventilator is sent into the tympanic chamber through the bracket by the tympanic tube inserter. The existing tympanic tube inserter is equipped with a "Z" sleeve, and the sleeve There is a push rod, a fixed handle is provided at the rear end of the sleeve, and a push handle is provided at the rear end of the push rod. When in use, the ventilation tube is supported on the front end of the sleeve through the bracket and placed into the tympanic chamber, and the sleeve is fixed through the fixed handle.
