Annular-like auditory ossicle prosthesis

Abstract

The invention discloses an annular-like auditory ossicle prosthesis. The annular-like auditory ossicle prosthesis comprises a dual-metallic-wire hook and a connector, wherein the upper end of the dual-metallic-wire hook is of a structure that two half-open circular rings, i.e., a small half-open circular ring and a big half-open circular ring are externally tangent, and the lower end of the dual-metallic-wire hook serves as a connecting part; the connector is of a cylindrical structure, and a plurality of annular grooves are formed in the external surface of the lower end of the connector; andpart of the connecting part of the lower end of the dual-metallic-wire hook is embedded in the connector. According to the auditory ossicle prosthesis disclosed by the invention, the dual-metallic-wire hook can be in high-efficiency contact link with stirrup bone and is not prone to unhooking and slide-off, and the stability and adaptability are higher; and the connector is of a cylindrical design, the outer edge of the bottom of the connector is of streamline microradian design, and thus, more-compatible link with an internal ear plunger can be achieved during implantation. By the annular-like auditory ossicle prosthesis, the problem of vibration conduction failure of a sufferer is effectively solved.

Description

technical field [0001] The invention relates to the field of anticipatory instruments, in particular to a ring-like auditory ossicle prosthesis. Background technique [0002] Due to disease, trauma or congenital deformity, the ossicles of the middle ear are usually vulnerable to damage. The ossicles of the middle ear are composed of three ossicles, also known as the ossicle chain. From the outside to the inside, they are: malleus, incus, and stapes. The arch of the stapes is formed by the floor of the stapes, which is in contact with the perilymph of the inner ear and is the last structure in the middle ear that transmits vibrations to the inner ear. The sound is caused by the vibration of the tympanic membrane to cause the vibration of the ossicular chain, so that the sound wave is transmitted to the inner ear, and the mechanical wave of the sound wave is converted into an electrical impulse through the sensory sound of the cochlear hair cells, so that the brain perceives t...

AI Technical Summary

Problems solved by technology

The double-wire hook of the ossicle prosthesis can efficiently connect with the stapes, and is not easy to dehook and slip, and has stronger stability and adaptability; the connector is designed in a cylindrical shape, and the outer edge of the bottom is designed with a streamlined micro-arc. It can be more compatible with the inner ear plug when implanted; the ring-like auditory ossicle prosthesis effectively solves the problem of vibration conduction failure of patients and brings good news to patients with ear diseases
