Description
Technical Field
The invention relates to the technical field of otology implanted medical devices, in particular to a self-locking artificial ossicular replacement body.
Background
The ossicular chain is the three small bones that connect between the tympanic membrane and the inner ear, which are the malleus, incus and stapes, respectively, wherein the stapes consists of the stapes arch and the stapes floor. The malleus is in contact with the tympanic membrane at the distal end of the external auditory canal, while the footplate of the stapes is in contact with the oval window membrane. The external sound causes the tympanic membrane to vibrate, the vibration is transmitted by ossicles and amplified by about 20dB to oval window membranes, lymphatic fluid in the membranes swings hair cells in cochlea, so that vibration signals are converted into nerve signals to be transmitted to brain, and the sound is heard by people.
In daily life, when the ossicular chain is damaged due to diseases, trauma or natural deformity, sound cannot be effectively transmitted to the inner ear, hearing is reduced and even hearing is lost, in order to repair the damaged ossicular chain to restore hearing function, ossicular chain reconstruction operation is required to be implemented, and in the operation, a doctor can replace the damaged ossicular chain by using autologous tissues (such as periosteum, fascia and the like) or artificial materials (such as titanium alloy chains, stearate chains and the like). These materials are capable of connecting the tympanic membrane to the inner ear, transmitting sound signals, thereby restoring hearing function.
However, clinical applications have found that a number of ossicular prostheses are dislocated or detached after implantation, mainly because they do not bond firmly to the stapes or footplate. Taking a part of the implanted ossicular prosthesis as an example, most of the implanted ossicular prosthesis and the stapes are connected in a bowl-shaped way, a movable gap exists between the implanted ossicular prosthesis and the stapes, and the implanted ossicular prosthesis and the stapes can only be pressed and not pulled in the axial direction, so that when the combined end of the prosthesis and the stapes is impacted or the tympanic membrane tissue grows and moves, the contact pressure is reduced, the prosthesis is easy to fall off, the hearing of a patient is damaged again, and a secondary operation is needed to adjust the position of the prosthesis.
