Embodiment Construction

[0013] See attached Figure 1~2 , the present invention comprises silica colloid 1 and cochlear-shaped pole array joint 2 pre-bent, pole array joint 2 is made up of 22 individual electrodes, each electrode is made up of electrode ring 7 and electrode wire 6, pole array joint 2 and silica gel The body 1 is packaged into one body, and several supporting sections 3 are arranged on the silicon body 1 facing away from the pole array 2. The supporting sections 3 and the silicon body 1 are integrated. An auxiliary ring 5 is provided, and the support section 3 is provided with a slender through-hole 10 parallel to the pole array 2, and the through-hole 10 penetrates the supporting steel core 4 in turn, and inserts the supporting steel core 4 into the plug in the end 8. hole, make the pre-bent cochlear-shaped electrode array 2 straight, use the rigidity of the supporting steel core 4 to transform the pre-bent electrode electrode array 2 from the pre-bent state to a straight state to fa...

Abstract

The invention discloses a polar array of artificial cochlear implant pre-bent electrode, which comprises a colloid silica and a polar array pre-bent like a cochlea, wherein the polar array consists of an electrode ring and an electrode wire, and is packed with the colloid silica as a whole. The polar array of artificial cochlear implant pre-bent electrode is characterized in that a plurality of supporting sections are arranged on the colloid silica facing away from the polar array, and are connected with the colloid silica into a whole, slender through holes parallel to the polar array are arranged on the supporting sections, the through holes penetrate the supporting steel cores to straighten the pre-bent cochlea polar array. The polar array is simple in structure, compared with the prior art, brings great convenience to the implanting operation of the polar array of artificial cochlear implant pre-bent electrode, allows the electrode closer to the spiral ganglion cell of the cochlea so as to improve the language discernibility, is low in power consumption and ensures that the implanted electrode works normally in the human body for a long time.

Description

technical field [0001] The invention relates to an artificial organ and its medical electronic device, in particular to an artificial cochlear pre-bent electrode array. Background technique [0002] The human ear can be divided into three parts: the outer ear, the middle ear and the inner ear. The main function of the outer ear and the middle ear is to conduct the external sound to the inner ear through the tympanic membrane and the three auditory ossicles connected to it. The inner ear is about the size of a soybean, shaped like a snail shell, also known as the cochlea. There are tens of thousands of auditory sensory cells in the cochlea—hair cells, which convert the acoustic energy (mechanical energy) from the middle ear into electrochemical energy to cause the excitation of the auditory nerve, which transmits the sound information to the cerebral cortex in the form of electricity And produce hearing. Deafness caused by inner ear hair cell lesions is sensorineural deafn...
