Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to auditory ossicle prosthesis of anchor nail structure.
Background
The ossicle (ossicle) is the smallest bone in the human body, also called ossicle, and the left and right ears are composed of three ossicles, anvil and stapes, most of which are located in the upper tympanic cavity and connected by ligaments and joints to form the ossicular chain. The malleus handle is arranged on the inner side surface of the tympanic membrane and is positioned between the mucosa layer and the fiber layer. The stapes footplate is connected to the oval window by an annular ligament. Between the hammer and the stapes is the incus.
Due to disease, trauma or congenital malformations, the incus are most commonly damaged. If the incus injury causes a discontinuity or fixation between the tympanic membrane and the stapes footplate, the vibrations transmitted from the tympanic membrane are not efficiently transmitted to the stapes bone, resulting in conductive hearing loss. When the damaged incus is replaced by the ossicular prosthesis, vibrations transmitted from the tympanic membrane will be transmitted by the ossicular prosthesis to the head of the stapes, thereby partially or fully compensating for the conductive hearing loss caused by the damage of the incus. In addition, the auditory ossicles in physiological states have the hammering block joint, the incudostapetum joint, the stapedial ring ligament, the soft link between the tympanic membrane and the malleus, and the ligaments of the malleus and the incus, so that the tympanic auditory ossicle chain system can buffer the middle ear cavity pressure changes. Such an auditory ossicle prosthesis replacing the malleus and/or the incus is also referred to as a partially artificial ossicle or a partially auditory ossicle prosthesis.
