Detailed description of the invention
As shown in the figure, a kind of medical tympanostomy tube inserter, 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 on 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 offered along surface, groove 5 is arranged on the position of core bar 2 near tail end, there is in groove 5 slide bar 6 arranged in parallel with core bar 2, one end of slide bar 6 is fixedly connected with groove 5 inwall, between the inwall of its other end and groove 5 opposite side, there is gap, groove 5 position of the corresponding core bar 2 of described trocar sheath 1 is equipped with control stick 7, it is inner that control stick 7 can stretch into groove 5 through slide bar 6 and the gap of groove 5 inwall, control stick 7 stretches out trocar sheath 1 one end and is provided with button 8, the other end of control stick 7 is connected with baffle plate 11, described control stick 7 is provided with the through hole 10 that can pass for slide bar 6, Compress Spring 9 is provided with between button 8 and trocar sheath 1.
The using method of this utility model breather inserter is: during original state, core bar is in contraction state, the head end of core bar does not stretch out trocar sheath, control stick stretches in groove, and slide bar is located in the through hole of control stick, before using, pressing pushes away handle makes core bar move, the head end of core bar stretches out trocar sheath, should until slide bar is relative with the lead to the hole site of control stick with the interstitial site of groove inner wall, now, slide bar is deviate from from through hole, control stick is outwards movement under the effect of Compress Spring, the baffle plate of the afterbody of final control stick mixes slide bar, the position of core bar in trocar sheath is fixed, 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, control stick is moved inward, when the lead to the hole site moving to control stick is corresponding with slide bar position, slide bar is through through hole, thus realize the contraction of core bar in trocar sheath, then trocar sheath is extracted out from auditory meatus, complete the placement of breather.
