Description

Technical Field

[0001] The utility model relates to the technical field of cochlear implants, in particular to cochlear implants. Background Art

[0002] A cochlear implant is an electronic device that converts sound into an electrical signal in a certain coded form through an external speech processor. It directly stimulates the auditory nerve through an electrode system implanted in the body to restore, improve and reconstruct the hearing function of the deaf. In the past two decades, with the development of high technology, cochlear implants have made rapid progress and have entered clinical application from experimental research. Now cochlear implants are used as a routine method for treating severe to complete deafness all over the world.

[0003] However, existing cochlear implants are usually a non-deformable connector. If this part is not customized during use, the cochlear implant may not fit the ear well for ears of different shapes and may easily fall off during use. Customized cochlear implants are expensive, which makes users reluctant to buy them. Therefore, there is an urgent need for a cochlear implant device to solve the above problems.

[0019] The utility model embodiment provides a cochlear implant, such as Figure 1-3 As shown, it includes a main body 11, an ear hook 14, an adjustment component, a processor 16 and a head piece 17. The surface of the main body 11 is provided with a protrusion that adapts to the human body. The upper side of the main body 11 is provided with an ear hook 14, and the ear hook 14 is symmetrically arranged. The processor 16 and the head piece 17 are arranged in the main body 11. The processor 16 converts the sound signal into a digital signal. The head piece 17 is electrically connected to the implant, and the head piece 17 is used to transmit the digital signal to the implant. A collection column 12 is fixedly provided on the lower side of the main body 11, and the adjustment component is arranged on the ear hook 14.

[0020] The ear hook 14 and the adjusting component form a cavity 15 with the main body 11, and the cavity 15 is used to fit with the patient's ear.

[0021] A connecting hole 18 is defined in the head member 17 .

[0022] like Figure 3As shown, the adjustment component includes an adjustment base 20 and a guide body 22. One end of the adjustment base 20 is fixed on one of the hanging ears 14. An adjustment slot 21 is opened in the adjustment base 20. The guide body 22 is arranged in the adjustment slot 21. The other end of the guide body 22 extends to the outside of the adjustment slot 21 and is fixed on the other hanging ear 14. The adjustment base 20 and the guide body 22 are both made of soft material.

[0023] The sound wave collector collects the sound waves reaching the patient's ear, the processor 16 converts the sound signal into a digital signal, and the headpiece 17 transmits it to the implant, and then reaches the inner ear, so that the auditory nerve receives the signal from the implant and transmits the nerve impulse to the brain, thereby bypassing the patient's damaged hair cells and allowing the patient to hear the sound.

[0024] The connection hole 18 is adapted to the shape of the wire plug.

[0025] The patient manually slides the adjustment base 20 along the guide body 22 to adjust the distance between the ear hooks 14 on both sides, thereby adjusting the internal space of the cavity 15, and then puts it on the patient's ear to complete the fixation, so that the patient can hear the sound while reducing the convergence pressure of the patient's ear and improving the patient's comfort.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
