Artificial cochlea cranked electrode and implanting method thereof

Abstract

The invention provides an artificial cochlea cranked electrode. The artificial cochlea cranked electrode comprises an electrode array link, and the electrode array link is bent into a cochlea shape and then is packed into a cranked electrode array link body through a colloidal silica body. The cranked electrode array link body is provided with a guide hose enabling the cranked electrode array link body to be straight, a horn mouth is formed in the tail end of the guide hose, and the guide hose is provided with a tearable structure penetrating through the head end and the tail end of the guide hose. The invention further provides an implanting method of the artificial cochlea cranked electrode. The implanting method comprises the steps that the horn mouth in the tail end of the guide hose of the artificial cochlea cranked electrode abuts against a windowing hole of the temporal bone of the human body, the artificial cochlea cranked electrode is slowly pushed into the temporal bone through the windowing hole of the temporal bone, the guide hose is made to gradually crack from the tearable structure, and the cranked electrode array link body is made to gradually recover the bent state and is matched with the human body cochlea completely; the cracked guide hose is taken out of the earhole, and then the cranked artificial cochlea is implanted. The artificial cochlea cranked electrode is simple in structure, convenient to implant, safe, reliable, high in language distinguishing ability, small in power consumption and long in service life.

Description

technical field [0001] The invention relates to an artificial organ and a medical electronic device thereof, in particular to an artificial cochlear curved electrode and an implantation method thereof. 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 external sound to the inner ear through the tympanic membrane and the three auditory ossicles connected to the tympanic membrane. 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 receptor cells in the cochlea, namely hair cells. The hair cells convert the sound energy transmitted from the middle ear into electrochemical energy, causing the excitation of the auditory nerve. The excitation of the auditory nerve transmits the sound information to the cerebral cortex in the form of electricity to pro...

AI Technical Summary

Problems solved by technology

Since the cylindrical hole to be inserted into the supporting steel core is relatively long and very thin, and most of the operation process is in a state where the visual effect is not very good. Bending leads to insertion failure, and it is easy to pierce the silicone package of the electrode array, destroying the insulating coating between the electrodes and affecting the use effect, which is very inconvenient to use
