Problems solved by technology

Furthermore, if the electrodes are located within the vestibular scala, stimulating currents in unipolar mode in addition to stimulating ganglion cells in the helical layer of the cochlea in the current circle, they are more likely to stimulate ganglion cells in the next more apical helical layer, which may lead to Cross stimulation and pitch confusion

Abstract

The invention discloses a directional electro-stimulation artificial cochlea electrode, which comprises a tip part, a universal joint, a first contact electrode array, a second contact electrode array, a silicon colloid, a first boosting ring, a second boosting ring, a first electrode wire array, a second electrode wire array, an annular loop electrode and a loop electrode lead. The artificial cochlea electrode reduces cochlear injury associated with surgical insertion and protects the cochlear structure; the electrode can be deeply inserted into the scala tympani to stimulate nerves with lower frequencies; the electrical stimulation efficiency is improved and the non-selective stimulation is reduced.

Description

technical field [0001] The invention relates to an electrode, in particular to a directional electric stimulation cochlear artificial electrode. Background technique [0002] A cochlear implant consists of an implant in the cochlea, a speech processor, a microphone and a transmission device. The sound is received by the microphone and converted into an electrical signal, and then sent to the speech processor to amplify and filter the signal, and then sent to the stimulator by the transmitter, and the generated electrical pulse is sent to the corresponding electrode contact, thereby stimulating the auditory nerve in the cochlea to generate excitement and Send sound information to the brain to produce hearing. In the whole cochlear implant system, the cochlear electrode is a very important part of the cochlear implant. [0003] The thickness of the inner wall of the scala tympani in some parts of the cochlea is only tens of microns, which is the only barrier between the coch...
