Abstract

The invention discloses a replaceable artificial auditory ossicle prosthesis device. The device comprises an elastic ear membrane affinity sheet, a crank, an elastic fixing pin and a base, wherein theelastic ear membrane affinity sheet is slidably connected with the top of the crank, and the bottom of the crank is fixedly connected with the base through the elastic fixing pin; the elastic ear membrane affinity sheet fits the ear membrane, and the base is fixed into the podalic plate. The device aims at solving the problem of hearing loss caused by prolapse, breakage, displacement and the likeof existing artificial auditory ossicle prosthesis devices after operations; a spring fixing pin is pulled out, a main body part is inserted, and then the spring fixing pin is inserted to complete the whole use process, so that the time of doctors during the operations is greatly saved, and the workload of the doctors during the operations is greatly reduced; through the operation of a sphericalstructure at the lower end of the crank and the position of the base, automatic adjustment is achieved according to the heights of the auditory ossicles of different human bodies, time for the doctorsto conduct cutting, grinding and the like is shortened, and the workload of cutting, grinding and the like is reduced for the doctors. The angle of the replaceable artificial auditory ossicle prosthesis device can be adjusted according to different ear membranes of each person.

Description

technical field [0001] The invention relates to a replaceable artificial ossicle prosthesis device, which belongs to the technical field of implantable medical devices in otology. Background technique [0002] Chronic otitis media is a common disease in otology that can cause hearing loss and fatal complications. As early as the early twentieth century, radical surgery was used to prevent fatal complications. With the development of surgical techniques and the in-depth study of the mechanism of sound transmission in the middle ear, otologists prefer to treat such diseases with functional surgery rather than radical surgery. Because in most cases, not only the lesion can be cleared from the middle ear and mastoid, but also the hearing can be reconstructed, and the integrity of the ossicular chain is the basis of sound transmission. [0003] Ossicle chain replacement surgery has relatively high requirements for physicians, and many situations will lead to postoperative artif...
