Detailed description of the invention
As shown in the figure, a kind of tube adapter for drum membrane device, comprise trocar sheath 1 and be located in the core bar 2 of trocar sheath 1 inside, the tail end of described core bar 2 stretches out trocar sheath 1 and is connected with and pushes away handle 3, push away handle 3 and be arranged with thin rubber cover, and push away between handle 3 and trocar sheath 1 and be provided with back-moving spring 4, described core bar 2 has the groove 5 radially offered, groove 5 is arranged on the position of core bar 2 near tail end.Control stick 6 is provided with in groove 5, one end of control stick 6 is connected by Compress Spring 7 with the bottom of groove 5, the other end of control stick 6 is hemispherical termination, described trocar sheath 1 is provided with the through hole 8 that can pass for control stick 6, 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 axis of push rod 10 and the dead in line of 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 is connected button 11, button 11 is arranged with thin rubber cover, the other end of push rod 10 can stretch in the through hole 8 of trocar sheath 1, described push rod 10 is also provided with back-up ring 12, back-up ring 12 be set in be positioned at housing 9 inside push rod 10 on, and back-up ring 12 is greater than the thickness of trocar sheath 1 with the distance away from button 11 one end of push rod 10.Be 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 tympanostomy tube apparatus for placing of the present utility model is: during original state, core bar is in contraction state, the head end of core bar does not stretch out trocar sheath, control stick is positioned at groove, and Compress Spring is in compressive state, control stick holds out against the inwall of trocar sheath, before using, pressing pushes away handle makes core bar move, the head end of core bar stretches out trocar sheath, until control stick is corresponding with the lead to the hole site on trocar sheath, now, control stick stretches in through hole under the effect of Compress Spring, make a part for control stick 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 external part of core bar from trocar sheath, singlehanded control core bar to stretch in auditory meatus and breather is accurately placed in tympanum incision, button is pressed with forefinger, thus push rod is moved radially, under the compressing of push rod, control stick finally from through hole depart from and under the effect of back-moving spring, realize the contraction of core bar in trocar sheath, then trocar sheath is extracted out from auditory meatus, complete the placement of breather.
