Description

Technical Field

[0001] The utility model relates to the technical field of cochlear implants, in particular to an artificial cochlear implant. 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 may break or fail when worn, especially for child users, who have a weak awareness of protecting the device. In addition, due to large amounts of exercise and a wide range of activities, the cochlear implant is easily damaged. At this time, if one cochlear implant is still working, the patient cannot identify the direction of the sound, causing defects in use and poor results for the patient. Utility Model Content

[0010] Preferably, the collection component includes a sliding sleeve and a sound wave collector, a fixed column is fixedly provided at the lower end of the collection column, a telescopic cavity is opened in the sliding sleeve, the sliding sleeve is sleeved on the fixed column through the telescopic cavity, the sound wave collector is fixed in the sliding sleeve, and the sound wave collector is electrically connected to the processor.

[0011] Preferably, the connection hole is adapted to the shape of the wire plug.

[0012] (III) Beneficial effects

[0013] The utility model provides a cochlear implant having the following beneficial effects:

[0014] 1. In this scheme, the patient holds the sliding sleeve to move the sliding sleeve axially along the outer surface of the fixed column, thereby adjusting the spatial position of the sound wave collector, and using the change in the position of the unilateral sound wave collector to achieve a binaural effect, so that the patient can identify the location of the sound source even if only one side can hear the sound.

[0019] The utility model provides a cochlear implant, such as Figure 1-3 As shown, it includes a main body 11, a collection component, an ear hook 14, 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, 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 collection component is arranged on the collection column 12.

[0020] like Figure 2 As shown, a cavity 15 is formed between the hanging ear 14 and the main body 11 .

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

[0022] like Figure 3 As shown, the collection component includes a sleeve 13 and a sound wave collector 22. A fixed column 21 is fixed at the lower end of the collection column 12. A telescopic cavity 20 is opened in the sleeve 13. The sleeve 13 is sleeved on the fixed column 21 through the telescopic cavity 20. The sound wave collector 22 is fixed in the sleeve 13, and the sound wave collector 22 is electrically connected to the processor 16.

[0023] The sound wave collector 22 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 holds the sliding sleeve 13 to move the sliding sleeve 13 axially along the outer circumferential surface of the fixed column 21, thereby adjusting the spatial position of the sound wave collector 22. The change in the spatial position of the sound wave collector 22 used to collect sound waves on one side is used to achieve a binaural effect, so that the patient can identify the location of the sound source even if only one side can hear the sound.

[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.
