Problems solved by technology

However, recognition is reduced in noisy areas where many people are talking
In addition, these people have difficulty enjoying music, especially showing very poor pitch sensitivity
[0009] In addition, traditional multi-channel cochlear implants have various disadvantages, such as high cost, very complicated operation and risk of causing disease

Embodiment Construction

[0038] Hereinafter, preferred embodiments of the present invention will be shown in more detail with reference to the accompanying drawings.

[0039] image 3 It is a schematic diagram of the internal receiving unit of the cochlear implant of the present invention. The internal receiving unit 100 includes a receiving part 110 that wirelessly receives an external signal, and an electrode part. The electrode portion includes an active electrode 120a and a reference electrode 120b.

[0040] Such as Figure 4 As shown, the active electrode 120a consists of three regions with different thicknesses. The first area I is connected to the receiving part 110 . The thickness of the second region II is smaller than that of the first region I, and the thickness of the third region III is smaller than that of the second region II. Alternatively, the thickness of the second region may be the same as that of the third region, if necessary. The first region I has the greatest thickness an...

Abstract

There is provided a cochlear implant for improving the hearing ability of a patient suffered from hearing impairment comprising an internal receiving unit implanted into the body, which comprises a receiving part for receiving external signal, an active electrode and a reference electrode, characterized in that the active electrode is constructed with a single electrode wire having different thickness in at least two different regions. The active electrode of the internal receiving unit is inserted into a space formed at between the mastoid bone and the ear canal skin and end of the active electrode is inserted into the scala tympani of the cochlea and directly stimulates spiral ganglion. The cochlear implant provides easier implantation into the body and improved hearing ability at a lower cost.

Description

technical field [0001] The present invention relates to a cochlear implant, and more particularly, to a cochlear implant that can be easily implanted and provides enhanced hearing ability. Background technique [0002] The ear is made up of three basic parts: the outer ear, the middle ear and the inner ear. Sound travels from the outer ear to the eardrum at the interface of the outer ear and then to the middle ear in the form of vibrating air waves. The sound is then transmitted to the oval window of the cochlea by vibrations of the auditory ossicles. As the fluid in the cochlea vibrates, the organ of Corti generates electrical signals. [0003] Vibration of the tectum induces the generation of a receptor potential in the hair cell, which is transmitted through the dendrites to the spiral ganglion. Signals from this spiral ganglion stimulate neurons in the auditory nerve and eventually travel to the brain. Most hearing loss is due to malfunctioning of the hair cells in t...
