{MYRINGOTOMY SURGICAL OPERATION APPARATUS FOR REMEDYING OTITIS MEDIA}

The present invention relates to an apparatus for treating ophthalmologic ear piercing, and more particularly, to a device for treating ophthalmic ophthalmology which is capable of forming a ventilation hole in the eardrum and inserting a tubular stent into the ventilation hole for treating otitis media .

As it is known, otitis media (otitis media) refers to all inflammation in middle ear and is one of the most common inflammation among bacterial infections in children.

It is known that these otitis media occur at the age of 6 months and begin to occur at the age of 2 years. Three out of every four children are known to have otitis media more than once before the age of 3 years.

Acute otitis media is an otitis media with acute inflammation within 3 weeks, accompanied by symptoms such as ear pain and fever. Exudative otitis media does not have symptoms of acute inflammation and the exudate, which is the liquid secreted from the mucous membrane, Disease. Overtous otitis media is usually a case of acute otitis media after acute inflammation disappears, only the exudate is left in the middle ear. The otitis media is usually caused by the mucous membrane of the eustachian tube being swollen by puffing with allergies, resulting in the generation of negative pressure inside the middle ear cavity and exudate from the periphery, resulting in the proliferation of bacteria.

Otitis media is usually treated with medications such as antibiotics. In the case of pain reduction or bacterial screening, it is necessary to use a syringe to pull out the exudate directly from the middle ear and to make a hole in the eardrum, It is also treated by the incision method.

Such otitis media can be prevented by various medical or surgical procedures. As an example, in cases of acute otitis media or chronic otitis media with otitis media, tympanostomy can be performed with a ventilation tube inserted into the eardrum to reduce the incidence of acute otitis media and otitis media have.

As described above, when the ventilation tube is inserted into the tympanic membrane, the possibility of otitis media is reduced and the hearing loss caused by the effusion is relieved because the middle ear is discharged and ventilated. Thus, the language disorder and balance disorder caused by chronic otitis media are solved, Disability can also be improved.

Typically, eardrum puncture can be performed by performing a myringotomy to form an incision in the eardrum, inserting a tube in the incision, and sucking the exudate from the middle ear through a tube with a suction device, In recent years, a system has been proposed in which a single system continuously executes eardrum incision and ventilation tube insertion.

In the meantime, as a prior art of the present invention, in the case of a hypertensive pressure balanced tube delivery system proposed in Korean Patent Laid-Open Publication No. 10-2012-0037480, an incision is automatically formed in the eardrum of the ear, .
