Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] Such as figure 1 Shown is a schematic structural view of a preferred embodiment of the present invention. The present invention proposes a replaceable artificial ossicle prosthesis device, including an elastic eardrum affinity piece 1, a crank 2, an elastic fixing pin 3, an abutment 4, an elastic eardrum The affinity sheet 1 is slidingly connected to the top of the crank 2, and the bottom end of the crank 2 is fixedly connected to the abutment 4 through the elastic fixing pin 3. The elastic eardrum affinity sheet 1 is attached to the eardrum 5, and the abutment 4 is fixed on the foot plate 6. middle.

Abstract

The invention discloses a replaceable artificial ossicle prosthesis device, comprising an elastic eardrum affinity piece, a crank, an elastic fixing pin, and an abutment, the elastic eardrum affinity piece is slidably connected with the top end of the crank, and the crank The bottom end of the eardrum is fixedly connected with the abutment through the elastic fixing pin, the elastic eardrum affinity sheet is attached to the eardrum, and the abutment is fixed in the foot plate. The present invention aims at the problem of hearing loss caused by the artificial ossicle prosthetic device after surgery, such as prolapse, breakage, displacement, etc., by pulling out the elastic fixing pin, inserting the main part, and then inserting the elastic fixing pin, greatly improving the hearing loss. Reduce the time and workload of the doctor during the operation; through the cooperation of the spherical structure at the lower end of the crank and the position of the abutment, it can be adjusted according to the height of the ossicles of different human bodies, reducing the time and work of the doctor for cutting and grinding. amount; the present invention can adjust the angle according to the difference of each individual's eardrum.

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...
