Lesions of ears system extension fixture

Technical field

The utility model relates to field of medical device more particularly to a kind of lesions of ears system extension fixtures.

Background technique

With reference to Fig. 1-2, ear 10 is divided into three parts: external ear 12, middle ear 14 and inner ear 16.External ear 12 is by auricle 18 and ear Road 20 forms, and auricle 18 and ear canal 20 collect sound and sound guidance are located to the eardrum 22 at the inner end 24 of ear canal 20 (also referred to as For ear-drum).Middle ear 14 are connected to throat rear portion between external ear 12 and inner ear 16 and through Eustachian tube 26, and Eustachian tube 26 fills Equalizing valve between ear 10 and sinus.Eustachian tube 26 terminates in the distal openings in the nasopharyngeal area 30 of throat 32 or mouth 28. In addition to ear-drum 22, middle ear 14 are also made of three small otica (phonophore): malleus 34 (hammer), incus 36 (anvil) and stapes 38 (stirrup).Acoustical vibration is transmitted to inner ear 16 by these bones 34-38, so that converter is served as, by the sound in the ear canal 20 of external ear 12 Sound vibrates the fluid wave being converted into inner ear 16.These fluid waves stimulate several nerve endings 40, and nerve endings 40 successively again will Acoustic energy transmissions are explained to brain and in brain.

Eustachian tube 26 measured from mouth 28 to bone isthmus 29 be two centimetres to two again half centimeter length slype, even Connect middle ear 14 and the nasopharynx 30 in the rear portion of nose, the upper bottle-neck section right above palate.Eustachian tube 26, which serves as, is normally filled with air The equalizing valve of middle ear 14.When fitting when activated, the response of Eustachian tube 26 is swallowed or is yawned periodically (three minutes one about every It is secondary) open part second.In doing so, replacement in middle ear 14 is allowed air into be absorbed by middle ear lining (mucous membrane) Air or the pressure change that occurs in altitude change of balance.Interference Eustachian tube 26 this periodically open and close it is any Factor can lead to hearing impairment or other ear symptoms.

The obstruction of Eustachian tube 26 or blocking lead to negative middle ear pressure 14, with the retraction (sucking) of ear-drum 22.In adult, this It is usually uncomfortable with some ears, it swells or feeling of stress, and can lead to slight hearing impairment and head noise (tinnitus).In children It is middle possible asymptomatic.If obstruction extends, fluid can be extracted out from the mucous membrane of middle ear 14, generate and be referred to as otitis media serosa The illness of (fluid is in middle ear).This is incorporated in children to the infection of the upper respiratory tract frequently occurs and is relevant with the illness The reason of hearing impairment.

Chronic serous otitis media can be caused by the long-term blockage of Eustachian tube or the thickening of fluid, prevent it is from being inhaled It receives or is discharged downwards along Eustachian tube 26.The chronic disease is usually with hearing impairment.There may be recurrent otalgia, especially when a When body-sensing emits.Fortunately, otitis media serosa sustainable many years and misalign ear mechanism and generate any permanent damage.So And the presence of fluid makes it vulnerable to the influence of Recurrent Acute infection in middle ear 14.These recurrent infections can lead to middle ear damage Wound.

When Eustachian tube 26 is gathered containing fluid, a variety of situations will occur.Firstly, body absorbs the sky from middle ear 14 Gas causes to be vacuum formed, which tends to inwardly pull lining form and ear-drum 22, so as to cause pain.Next, body is with more Fluid replaces vacuum, this tends to mitigate pain, but patient can undergo the sense of swelling in ear 10.It is controlled with antihistaminic and decongestant Treating the illness can spend several weeks just fully effective.Finally, Versatile must be infected, this is pain and makes the patient feels Discomfort, and can promote patient that cannot hear well.If inner ear 14 is impacted, patient can feel sense of rotation or steering feeling (dizziness).

Typical disease associated with middle ear and Eustachian tube include tympanic member perforation, tympanosclerosis, incus erosion, tympanitis, Cholesteatoma, mastoiditis, undue patency of eustachian tube and conductive hearing loss.It is some in order to treat these diseases, it can be performed Otologic Surgical Proce- dures.Most of Otologic Surgical Proce- dures are the micrurgies carried out with surgical operation microscope.The type of Otologic Surgical Proce- dures includes Stapedectomy, myringoplasty, tympanotomy and syrinx operation.These Otologic Surgical Proce- dures are due to very pain, for patient Body and mind cause tremendous influence.

Middle ear and Eustachian tube slight illness are very universal and serious medical problems, perplex millions of people and cause pain, no Accommodate even hearing disability or permanent hearing impairment.Therefore, it is necessary to for close to the target tissue region in middle ear and Eustachian tube Device.It is desirable that such device will be minimally invasive and cause very small the risk of harm to the ear tissue of health.
