Abstract

The invention discloses an auditory ossicle prosthesis. The auditory ossicle prosthesis comprises a middle rod; a supporting plate and a connector are arranged at the two ends of the middle rod respectively; the supporting plate is used for being connected with the tympanic membrane; the connector is used for being connected with the stapes; the supporting plate and the connector are both integrally formed together with the middle rod; the included angle between the middle rod and the plane where the supporting plate is located is smaller than 90 degrees; the supporting plate is formed in an oval shape corresponding to the shape of the tympanic membrane; the connecting point of the supporting plate and the middle rod does not coincide with the circle center of the supporting plate; and the middle rod is a telescopic elastic rod-shaped piece. All the structures are integrally formed, the effect of transmitting vibration of the tympanic membrane is good, and the postoperative recovery effect of a patient is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a titanium periosteum-based auditory ossicle prosthesis. Background technique [0002] The ossicle is the smallest bone in the human body, also known as the ossicle. The three ossicles in the left and right ears are composed of the malleus, incus and stapes. Most of them live in the upper tympanic cavity and are connected by ligaments and joints. Ossicle chain. The mantle of the malleus is located on the medial surface of the tympanic membrane, between the mucosal and fibrous layers. The foot plate of the stapes is connected to the oval window by the annular ligament, and the incus is between the hammer and the stapes. Due to disease or congenital reasons, the ossicles are damaged, and it is generally necessary to implant an ossicle prosthesis through surgery to replace the ossicles. [0003] Chinese patent CN109730809A discloses a low-stress rotatable auditory ossicle pr...
