The tail end of the core rod extends out of the outer cannula and is connected with a push handle, a reset spring is arranged between the push handle and the outer cannula, the core rod is provided with a groove formed along the surface, 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 the sliding rod and the inner wall of the opposite side of the groove, a control rod is arranged on the position, corresponding to the groove of the core rod, of the outer cannula in a penetrating mode, the control rod can penetrate through the gap between the sliding rod and the inner wall of the groove and extend into the groove, the control rod is provided with a through hole allowing the sliding rod to penetrate, the end, extending out of the outer cannula, of the control rod is provided with a button, and a compressed spring is disposed between the button and the outer cannula. The ventilation tube catheterization device is convenient to use, the view of operators is wide, and catheterization efficiency and the treatment effect of a ventilation tube can be obviously improved.

Description

A kind of medical tympanostomy tube inserter

Technical field

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

Background technology

As everyone knows, the patients such as the 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, when 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, when 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 medical tympanostomy tube inserter 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 medical tympanostomy tube inserter, comprise trocar sheath and be located in the core bar of 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, control stick stretches out trocar sheath one end and is provided with button, the other end of control stick is connected with baffle plate, on described control stick, be provided with the through hole that can pass for slide bar, 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 the position of core bar near tail end.

beneficial effect

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

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 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 the position of core bar 2 near 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, 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, on described control stick 7, be provided with the through hole 10 that can pass for slide bar 6, between button 8 and trocar sheath 1, be provided with Compress Spring 9.

The using method of breather inserter of the present invention is: when 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 baffle plate of the afterbody of final control stick is mixed slide bar, the position of core bar in trocar sheath fixed, then breather is placed in to the external part of core bar from 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.
