Abstract
The invention relates to a novel artificial eardrum, which is characterized in that the eardrum is synthesized by chemical substances, does not have any toxicity and rejection reactions on a human body at all, can be dissolved and absorbed automatically after certain time, has the same thickness as the normal eardrum, a porosity of 50 percent and certain hardness and toughness, does not become soft and deform encountering a liquid, has the size which can be cut out according to the needs of operations, and can be dyed with various colors different from the eardrum for the convenience of distinguishing during the operations. Besides, the novel artificial eardrum can be applied to eardrum repairing operations through any methods such as a lining method, a sandwich method, an external sticking method and the like, and is a comparatively ideal artificial material for eardrum repairing. The novel artificial eardrum contributes to exploring and researching a new generation of artificial tissue repairing materials, has significant social benefit, and can improve the audition and improve the life quality for millions upon millions of conduction deafness sufferers.
Description
A kind of novel artificial tympanum, particularly a kind of synthetic by chemical substance, there are not any toxicity and rejection, can dissolve the novel artificial tympanum of absorption behind the certain hour voluntarily.
Obtained very big progress at various artificial organs of development and organizational aspects both at home and abroad at present.That has succeedd 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 all kinds of dysaudia people with disabilitys to reach 200,000,000 5 thousand ten thousand more than, and only China just has closely more than 3,000 ten thousand, wherein belongs to transmission deafness and need be the patient of tympanum repairing operation and have nearly 10,000,000 approximately.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, vein 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 much thick than normal tympanum in addition, so influence the postoperative auditory rehabilitation, and to meet blood and water be that deliquescing is out of shape and is caused the operation technique difficulty.Allosome material then 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 novel artificial tympanum that can overcome above various defectives will be provided.
Content of the present invention and feature:
Invent a kind of novel artificial tympanum, it is characterized in that by chemical substance synthetic, human body there are not any toxicity and rejection, thickness is the same with normal tympanum, has 50% porosity, certain rigidity and toughness, meet not deliquescing of liquid distortion, and the big I art of whipping need cut randomly, and can dye different and diaphragm-operated shades of colour, to differentiate in the convenient operation.After the operation of this kind novel artificial tympanum is implanted, in the tympanum growth course, mainly play a bridging, treat to dissolve absorption (about about 30 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. a novel artificial tympanum is synthesized by chemical substance, does not have any toxicity and rejection, can dissolve absorption voluntarily behind the certain hour.
2. novel artificial tympanum according to claim 1 is characterized in that thickness and normal tympanum the same (0.1mm), has 50% porosity, and certain rigidity and toughness are met not deliquescing of liquid distortion.
3. novel artificial tympanum 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. novel artificial tympanum according to claim 1 is characterized in that can be used for the tympanic membrane repairing of any method, as interior reinforcement, sandwich method, external application method etc.
