Description

Tube adapter for drum membrane clamps

Technical field

This utility model relates to a kind of tube adapter for drum membrane pincers, and it belongs to technical field of medical instruments.

Background technology

In otological disease, secretory otitis media is commonly encountered diseases, frequently-occurring disease.Secreted for recurrent exerbation Otitis media patient, due to its dysfunction of eustachian tube, makes tympanum inadequate drainage, formed tympanum negative pressure and (or) Hydrops, thus cause auditory dysesthesia, even can produce the most serious sequela such as adhesive otitis media.? It is frequently necessary to use tympanostomy tube in the treatment of secretory otitis media, it is drain that tympanostomy tube is implanted in operation Hydrops in tympanum, balancing drum indoor and outdoor pressure, improve the important means of ventilation of tympanic cavity.

Tympanostomy tube is in use at present, needs veteran doctor hand perforation on the tympanum of patient, Then, by tympanostomy tube not in the hole put on, patient is stimulated relatively big by this process, and pain is substantially；Once Perforate is excessive, then be easily caused tympanostomy tube and come off, so that patient needs repeat surgery, to patient Cause secondary injury.

Utility model content

This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of tube adapter for drum membrane pincers.

The technical scheme that this utility model solves above-mentioned technical problem is as follows:

A kind of tube adapter for drum membrane pincers, are respectively equipped with clamp handle first and the clamp handle second of push rod first and push rod second including front end； Be provided with return spring between described push rod first and push rod second, front end is provided with sting device；Described sting device Including being located at the puncture needle of push rod first front end and being located at the spacing ring of push rod second front end, described spacing ring and push rod First coaxial line and be positioned at puncture needle front end.

Compared with prior art, the beneficial effects of the utility model are: tympanostomy tube is in the support of puncture needle Under through spacing ring, utilize spacing ring to be tightened up as receiving umbrella by the baffle plate of tympanostomy tube end, thus Reduce the aperture of auripuncture so that tympanostomy tube difficult drop-off after installation, and the wound to patient's tympanum Wound reduces, operation technique simple and fast.

On the basis of technique scheme, this utility model can also do following improvement.

Further, the end in clamp handle first and clamp handle second is equipped with finger sleeve ring.

Use above-mentioned further scheme to provide the benefit that: finger sleeve ring so that more accurate when doctor operates, And can effectively prevent instrument landing, easily facilitate operation.

Detailed description of the invention

Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining This utility model, is not intended to limit scope of the present utility model.

A kind of tube adapter for drum membrane pincers, including with the clamp handle first 1 of finger sleeve ring and clamp handle second 2, at clamp handle first 1 and pincers The front end of handle second 2 is respectively equipped with push rod first 5 and push rod second 4；Set between described push rod first 5 and push rod second 4 Return spring 3, front end is had to be provided with sting device 6；Described sting device 6 includes being located at push rod first 5 front end Puncture needle 7 and the spacing ring 8 being located at push rod second 4 front end, described spacing ring 8 and push rod first 5 coaxial line and position In puncture needle 7 front end.

This utility model is when making, and the external diameter of puncture needle 7 and the internal diameter size of spacing ring 8 are as follows, punctures Pin 7 just can pass body 9, just can pass through spacing ring 8 after baffle plate 10 compression.

In use, supporting tympanostomy tube is as it is shown on figure 3, include body 9 and arrange for this utility model At the baffle plate 10 of its one end, described baffle plate 10 has the through hole that the cavity with described body 9 is connected.? During making, baffle plate 10 is relatively thin quality of rubber materials, has elasticity, can arbitrarily be compressed, can be voluntarily after release Recover its original shape.

In tube adapter for drum membrane is performed the operation, push rod second 4 is pulled back by first release clamp handle first 1 and clamp handle second 2, Distance between puncture needle 7 and spacing ring 8 is widened, now the body 9 of tympanostomy tube is sleeved on On puncture needle 7 so that baffle plate 10 is positioned at the front end of puncture needle 7, then shrinks clamp handle first 1 and clamp handle second 2, Push rod second 4 slightly being enforced body 9 move ahead, now baffle plate 10 is retracted in spacing ring 8；Then will Spacing ring 8 is close to patient's tympanum, clamp handle of firmly holding with a firm grip first 1 and clamp handle second 2, then puncture needle 7 tip penetrates drum While film, baffle plate 10 is driven to penetrate tympanum together with body 9；Finally, treat that baffle plate 10 is extensive in tympanum After its original shape multiple, extract puncture needle 7.

Above-mentioned operation process wound is less, significantly reduces the pain of patient, the most simple and efficient to handle, Relatively low to the skill requirement of medical personnel.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all Within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should wrap Within being contained in protection domain of the present utility model.
