Abstract
An artificial tympanic membrane for repairing human tympanic membrane is prepared from chemical substances through synthesis. Its advantages are no poison and rejection reaction, self dissolving or absorbing in a certain time, a certain hardness and toughness, and no deformation. It can serve as an ideal artificial material for tympamic membrane repairing.
Description
A kind of artificial ear drum, particularly a kind of by synthetic, no any toxicity of chemical substance and rejection, can dissolve the artificial ear drum of absorption voluntarily behind the certain hour.
Obtained very big progress at various artificial organs of development and organizational aspects both at home and abroad at present, that has succeeded mainly contains: artificial heart, artificial bone, artificial joint, artificial intraocular lenses, artificial auditory ossicle etc., but artificial ear drum does not see that so far report is arranged.According to World Health Organization's recent statistics, the whole world has the dysaudia people with disability to reach 200,000,000 5 thousand ten thousand more than, and only China just has closely 5,000 ten thousand, wherein belongs to the patient about 20,000,000 that transmission deafness need be done the tympanum repairing operation.Having only autologous material and allosome material two classes aspect the tympanum patching material at present, autologous material mainly contains periosteum, tragus perichondrium, temporalis fascia, venous valve of mastoidea etc., and allosome material mainly contains egg membrane, Cortex Bulbus Allii, gelfoam etc.But no matter be that autologous material or allosome material all exist different defectives, needing to do otch again at other positions of patient as autologous material when performing the operation obtains, so increased the weight of patient's misery, these autologous materials are all than thick many of normal tympanum in addition, so influence the postoperative auditory rehabilitation, and chance liquid is that the deliquescing distortion causes the operation technique difficulty.Allosome material all has rejection in various degree, and sterilization is difficult, and postoperative is difficult for surviving.
Purpose of the present invention is exactly that a kind of artificial ear drum that can overcome above various defectives will be provided.
Content of the present invention and feature:
Invent a kind of artificial ear drum, it is characterized in that by chemical substance synthetic, human body there are not any toxicity and rejection, thickness and normal tympanum the same (about 0.1mm is thick), have certain rigidity and toughness, meet not deliquescing of liquid distortion, and the big I art of whipping need cut randomly, and can dye and be different from diaphragm-operated shades of colour, to differentiate in the convenient operation.After the operation of this kind artificial ear drum is implanted, in the tympanum growth course, mainly play a bridging, treat to dissolve absorption (about about 40 days) voluntarily after tympanum heals well.This artificial ear drum can be used for the tympanic membrane repairing of any method in addition, as liner method, sandwich method, external application method etc., is that a kind of comparatively ideal tympanum is repaired artificial material.
This invention helps exploratory development a new generation artificial organ repair materials, and its social benefit is huge, can make millions upon millions of transmission deafness patients improve audition, improves the quality of living.
Claims (4)
1. an artificial ear drum is synthetic by chemical substance, does not have any toxicity and rejection, can dissolve absorption voluntarily behind the certain hour.
2. artificial ear drum according to claim 1 is characterized in that thickness and normal tympanum the same (about 0.1mm is thick), has certain rigidity and toughness, meets not deliquescing of liquid distortion.
3. artificial ear drum according to claim 1 is characterized in that the big I art of whipping need cut randomly, and can dye and be different from diaphragm-operated shades of colour.
4. artificial ear drum according to claim 1 is characterized in that can be used for the tympanic membrane repairing of any method, as liner method, sandwich method, external application method etc.
