Method for fixing artificial cochlea implanting device

Abstract

The invention discloses a method for fixing an artificial cochlea implanting device, which is characterized in that the method uses titanium plates to fix an artificial cochlea electrode and a decoder which are implanted into the body respectively; the titanium plate for fixing the electrode is a strip sheet, and the middle part of the titanium plate is transversely provided with a semicircular through groove, and the two sides of the semicircular through groove are provided with a plurality of fixing holes; the titanium plate for fixing the decoder is a strip sheet of which middle part is provided with a convex edge, and the strip sheet is provided with a plurality of fixing holes; and the method comprises the following specific steps: manufacturing the fixing titanium plates, pre-bending and fixing. Compared with the prior art, the method solves the problems that the artificial cochlea cannot produce displacement and dislocation of stimulating electrode and the like in the human body, further improves the reliability and safety of the artificial cochlea, and avoids the hidden danger that the stimulating electrode after the operation cannot work normally because the decoder is released from a mounting groove and rotates in the groove so as to drive the stimulating electrode.

Description

technical field [0001] The invention relates to an artificial organ implantation device, in particular to a fixing method for an artificial cochlear implantation device. Background technique [0002] The cochlear implant is an electronic device with a high content of bionics technology at present, and it is mainly used to help patients with severe or extremely severe deafness who wear hearing aids that are not effective or ineffective at all. The cochlear implant converts sound waves into weak current signals and transmits the current signals to the inner ear (cochlea). The multi-channel electrodes implanted in the cochlea stimulate the auditory nerve fibers in the cochlea to generate nerve impulses and transmit the nerve impulses to the brain. Thus forming the sense of hearing. [0003] At present, during the operation of cochlear implantation devices, auxiliary fixation is generally not added. Even if auxiliary fixation is added, that is, sutures with low strength are use...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for fixing a cochlear implant device in view of the deficiencies in the prior art, which uses a titanium plate to fix the implant device, so that the cochlear implant will not be displaced in the human body, and the problems such as dislocation of the stimulating electrode will not occur , further improving the reliability and safety of cochlear implants
