Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cutting-free artificial ossicular prosthesis structure. Background Art

[0002] In the existing technology, hearing conduction requires the eardrum to vibrate the ossicular chain, and then the ossicular chain conducts the sound energy to the inner ear. Many diseases such as otitis media, middle ear cholesteatoma, congenital developmental abnormalities of the middle ear, etc. will cause the problem of conductive hearing loss due to the interruption or fixation of the ossicular chain. In order to solve this type of conductive hearing loss problem, it is necessary to use artificial ossicular chains to reconstruct hearing during middle ear surgery. There are two main surgical methods for artificial ossicular chain hearing reconstruction, one is staged surgery and the other is simultaneous surgery. The staged surgery first removes the lesion and repairs the eardrum, and then implants the artificial ossicular chain one year after the operation. The simultaneous surgery implants the artificial ossicular chain while removing the lesion and repairing the eardrum. Since the newly repaired eardrum will slowly move outward or due to The Eustachian tube is sunken due to functional problems of the Eustachian tube. Implanting artificial ossicles after the tympanic membrane is repaired is conducive to more accurate selection of artificial ossicles of appropriate length. Therefore, staged surgery can select more suitable artificial ossicles than simultaneous surgery. However, staged surgery requires two operations, while simultaneous surgery only requires one operation, but there is a problem of inappropriate length of artificial ossicles. If the implanted artificial ossicles are too long, they are prone to dislocation, and if they are too short, they will be separated from the tympanic membrane after the tympanic membrane is externalized. Since the size and shape of each person's ossicles are different; during the operation, the doctor has to perform other processing such as polishing after completing the measurement, and then compare and polish again, which greatly increases the doctor's workload and is not conducive to the implementation of the implantation surgery.
