Abstract

The invention relates to a tympanostomy tube placement device which comprises an outer sleeve and a core rod arranged in the outer sleeve in a penetrating mode. The tail end of the core rod stretches out of the outer sleeve and is connected with a push handle, a reset spring is arranged between the push handle and the outer sleeve, a groove is formed in the surface of the core rod, a sliding rod parallel to the core rod is arranged in the groove, one end of the sliding rod is fixedly connected with the inner wall of the groove, a gap is formed between the other end of sliding rod and the inner wall of the opposite side of the groove, the position, corresponding to the groove of the core rod, of the outer sleeve is provided with a control rod in a penetrating mode, the control rod can penetrate through the gap between the sliding rod and the inner wall of the groove to stretch into the groove, a through hole allowing the sliding rod to penetrate is formed in the control rod, a button is arranged at the end, stretching out of the outer sleeve, of the control rod, and a compression spring is arranged between the button and the outer sleeve. The tympanostomy tube placement device is convenient to use, the sight of operators is good, and the placement efficiency and the treatment effect of tympanostomy tubes can be improved obviously.

Description

A kind of tympanostomy tube apparatus for placing

Technical field

The present invention relates to medical equipment technical field, be specifically related to a kind of tympanostomy tube apparatus for placing.

Background technology

As everyone knows, the patients such as hydrotympanum to secretory otitis media or the initiation of other reason will carry out tube adapter for drum membrane hands art, so that in tympanum, outer connection, to realize except liquid, the object of ventilation, tube adapter for drum membrane generally adopts silica gel to make now dumbbell shape angle breather or T-shaped breather, during treatment, breather is sent into tympanum through bracket by tympanostomy tube inserter, existing tympanostomy tube inserter is provided with " Z " sleeve pipe, in sleeve pipe, be provided with push rod, sleeve pipe rear end is provided with fixed handle, putting back-end is provided with and pushes away handle, during use, by breather through bracket holder at sleeve pipe front end and insert tympanum place, after fixing sleeve pipe, fixed handle pushes away handle, push rod moves forward in sleeve pipe, breather is sent in the tympanum through hole having bored, the deficiency of this tympanostomy tube inserter is that operator's sight line is poor, sleeve pipe fixed effect is poor, these all directly affect accuracy and therapeutic effect that breather is inserted.

Summary of the invention

The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of tympanostomy tube apparatus for placing is provided, easy to use, operator's sight line is good, and that can obviously improve breather inserts efficiency and therapeutic effect.

The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of tympanostomy tube apparatus for placing, the core bar that comprises trocar sheath and be located in trocar sheath inside, the tail end of described core bar stretches out trocar sheath and is connected with and pushes away handle, and push away between handle and trocar sheath and be provided with back-moving spring, on described core bar, there is the groove of offering along surface, in groove, there is the slide bar being arranged in parallel with core bar, one end of slide bar is fixedly connected with groove inwall, between the inwall of its other end and groove opposite side, there is gap, the groove location of the corresponding core bar of described trocar sheath is equipped with control stick, control stick can stretch into inside grooves through the gap of slide bar and groove inwall, on described control stick, be provided with the through hole that can pass for slide bar, and control stick stretches out trocar sheath one end and is provided with button, between button and trocar sheath, be provided with Compress Spring.

Describedly push away handle and button is all arranged with thin rubber cover.

Described groove is arranged on core bar near the position of tail end.

beneficial effect

Tympanostomy tube apparatus for placing of the present invention, easy to use, operator's sight line is good, and that can obviously improve breather inserts efficiency and therapeutic effect.

Fig. 3 is the partial structurtes schematic diagram of apparatus for placing of the present invention core bar groove when in running order;

Fig. 4 is the partial structurtes schematic diagram of apparatus for placing of the present invention core bar groove when original state;

Labelling in figure: 1, trocar sheath, 2, core bar, 3, push away handle, 4, back-moving spring, 5, groove, 6, slide bar, 7, control stick, 8, button, 9, Compress Spring, 10, through hole.

The specific embodiment

As shown in the figure, a kind of tympanostomy tube apparatus for placing, the core bar 2 that comprises trocar sheath 1 and be located in 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 and on handle 3, be arranged with thin rubber cover, and push away between handle 3 and trocar sheath 1 and be provided with back-moving spring 4, on described core bar 2, there is the groove 5 of offering along surface, groove 5 is arranged on core bar 2 near the position of tail end, in groove 5, there is the slide bar 6 being arranged in parallel with core bar 2, one end of slide bar 6 is fixedly connected with groove 5 inwalls, between the inwall of its other end and groove 5 opposite sides, there is gap, groove 5 positions of the corresponding core bar 2 of described trocar sheath 1 are equipped with control stick 7, control stick 7 can stretch into groove 5 inside through slide bar 6 and the gap of groove 5 inwalls, on described control stick 7, be provided with the through hole 10 that can pass for slide bar 6, and control stick 7 stretches out trocar sheath 1 one end and is provided with button 8, on button 8, be arranged with thin rubber cover, between button 8 and trocar sheath 1, be provided with Compress Spring 9.

The using method of 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 stick stretches in groove, and slide bar is located in the through hole of control stick, before use, press and push away handle core bar is moved, 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 inwall, now, slide bar is deviate from from through hole, control stick outwards moves under the effect of Compress Spring, the afterbody of final control stick withstands slide bar, the position of core bar in trocar sheath fixed, then breather is placed in to core bar from the external part of trocar sheath, singlehanded control stretched into core bar in auditory meatus and by breather and is accurately placed in tympanum incision, use forefinger pressing button, control stick is moved inward, when moving to the lead to the hole site of control stick when corresponding with slide bar position, slide bar is through through hole, thereby realize the contraction of core bar in trocar sheath, then trocar sheath is extracted out from auditory meatus, complete the placement of breather.
