Abstract
A tympanic ventilation tube device for use in incising an ear drum and ensuring continued drainage of fluid from the middle ear comprises a tube, a first flange connected to one end of the tube, and a second flange connected to an opposite end of the tube, the first flange being provided with a cutting edge. The cutting edge includes a pair of straight edge segments oriented at an acute angle to one another to form a cutting wedge extending away from the second flange. A graspable extension is connected to the second flange and projects therefrom on a side thereof opposite the first flange. The ventilation tube is installed by using an elongate applicator rod or obturator releasably coupled to the tube. The rod is made of a material such as a metal or alloy having a limited malleability. Accordingly, the applicator rod may be reconfigured prior to the application of the ventilation tube, thereby facilitating the insertion of the tube at an appropriate position in the tympanic membrane. The applicator rod is joined to the ventilation tube by having a distal end detachably inserted into a proximal end of the tube.
