How much is the cochlear implant?[Electronic cochlear cost]
How much is the cochlear implant?Cochlear implants are three types of medical devices, which are divided into two parts: the external processor and the implant. The implant needs surgical implantation. Probably the working principle is that the external processor accepts the sound post-processing, transmitting a signal to the implant, and the implant directly stimulates the auditory nerve through the current. “Electric” stimulation is the way to hear the sound. The cochlear implant is the first “artificial organ” in human history that completely replaces an organ. The cochlear implant is an “artificial ear” that replaces the ear. The hearing aid is an amplifier, but because the hearing loss is not linear, so more digital hearing aids are used now. It is not a simple amplification, but some frequency loss is more serious, and some frequency loss is smaller. This way the hearing aid can effectively compensate for hearing. Or the sound is amplified, through the tympanic membrane, ossicular chain, cochlea, and auditory nerve to reach the brain, which is regarded as the “enhancement device” of the ear. Currently generally considered90Below the decibel, the hearing aid can be effective for hearing aids.90Above the decibel, the hearing aid compensation effect is limited, it is usually recommended to make a cochlear implant. However, under what circumstances is the hearing aid, and under what circumstances the cochlea is based on the actual situation of the patient. The effective range of the cochlear implant and hearing aid itself is not very clear. such as70Decibels below, definitely hearing aids;90Above the decibel, usually the cochlea; but70-90It is also a hearing aid, and it can also be implanted in some developed areas of hearing and hearing abroad.
A cochlear implant is an electronic device that helps patients with severe and deep deafness gain or restore hearing. It replaces the damaged auditory organ and converts the sound into a coded electrical signal that is transmitted to the inner ear cochlea, stimulating the auditory nerve fibers distributed there. Then the brain produces hearing.
Cochlear implants include in vitro speech processors and headpieces as well as implant components in the body.
The speech processor processes the audio signal and encodes it into an electrical signal, similar to a portable computer. The body-worn speech processor is connected to the headpiece by wires. The behind-the-ear speech processor and the microphone are combined into one, which can be worn behind the ear, which is convenient and beautiful.
The head piece includes a behind-the-ear directional microphone, a transmission coil, a magnet, and a wire.
The implant components are made of materials such as ferroalloy, platinum and silica gel, which have been proven to be compatible with human tissue. Electrode group:It consists of a set of electrodes made of platinum material. Receiving stimulator:It is made of a tough, impact-resistant titanium alloy and is covered with a silicone layer. This design guarantees the safety of use and allows the implanter to have a more active life without being overly restricted. The implanted parts are thin and flexible and can be shaped with the head shape of the implanter. At the same time adapt to the requirements of growth and development, especially suitable for children to implant.
The external part of the microphone collects the sound through the language processor to encode the sound signal, and the sensor coil in the head piece is wirelessly transmitted to the implanted part of the body. The implanted components in the body need to be installed in the human body through cochlear surgery. It receives electrical signals and replaces the damaged cochlea by the electrodes implanted in the cochlea according to the language coding scheme.
