Detailed description of the invention
As shown in the figure, a kind of tube adapter for drum membrane device, including trocar sheath 1 and be located in the core bar 2 within trocar sheath 1, the tail end of described core bar 2 stretches out trocar sheath 1 and is connected to push handle 3, push handle 3 is arranged with thin rubber set, and between push handle 3 and trocar sheath 1, it is provided with back-moving spring 4, and described core bar 2 has the groove 5 radially offered, groove 5 is arranged on the core bar 2 position near tail end。Control bar 6 it is provided with in groove 5, control one end of bar 6 to be connected by compressing spring 7 with the bottom of groove 5, the other end controlling bar 6 is hemispherical termination, described trocar sheath 1 is provided with the through hole 8 being available for controlling bar 6 traverse, this through hole 8 place is covered with housing 9, in housing 9, the position of corresponding through hole 8 is equipped with push rod 10, the dead in line of the axis of push rod 10 and through hole 8, and the diameter of push rod 10 is less than the diameter of through hole 8, one end of push rod 10 is stretched out housing 9 and connects button 11, button 11 is arranged with thin rubber set, the other end of push rod 10 can stretch in the through hole 8 of trocar sheath 1, described push rod 10 is additionally provided with back-up ring 12, back-up ring 12 is set on the push rod 10 being positioned within housing 9, and the distance away from button 11 one end of back-up ring 12 and push rod 10 is more than the thickness of trocar sheath 1。Being provided with restoring spring 13 between described back-up ring 12 and trocar sheath 1, restoring spring 13 is set on push rod 10, and when making original state, back-up ring 12 presses closer housing 9 inwall。
The using method of the tympanostomy tube apparatus for placing of the present invention is: during original state, core bar is in contraction state, the head end of core bar does not stretch out trocar sheath, control bar and be positioned at groove, and compression spring is in compressive state, control the inwall of the tight trocar sheath of masthead, before using, pressing push handle makes core bar move, the head end of core bar stretches out trocar sheath, until it is corresponding with the lead to the hole site on trocar sheath to control bar, now, control bar and stretch in through hole under the effect of compression spring, make a part for control bar in through hole, its another part is in groove, what achieve between trocar sheath and core bar is locked, then breather is placed in the core bar external part from trocar sheath, core bar is stretched in auditory meatus and breather is accurately placed in tympanum incision by singlehanded control, button is pressed with forefinger, so that push rod moves radially, under the compressing of push rod, control bar finally to depart from and under the effect of back-moving spring from through hole, realize core bar contraction in trocar sheath, then trocar sheath is extracted out from auditory meatus, complete the placement of breather。
