Problems solved by technology

[0002] Cochlear implantation is a conventional method for the treatment of deafness. The external speech processor converts the sound into a certain coded electrical signal, and directly stimulates the auditory nerve through the stimulating electrode implanted in the body to restore, improve and rebuild the auditory function of the deaf. The electrode is the most important functional part of the cochlear implant, which needs to be implanted into the patient's helical cochlear lumen. In today's minimally invasive cochlear implant surgery, the stimulating electrode can be directly implanted through a long and narrow drilling channel Into the inner cavity of the cochlea of ​​the patient, during the implantation process

Abstract

The invention relates to an implanting device of an artificial cochlea. The device comprises a base, a shell, a vertical adjusting mechanism arranged on the shell, a tension detection mechanism connected with the vertical adjusting mechanism and a clamp installed on the side face of the shell and used for clamping a catheter, wherein the bottom of the front end of the device is hinged to the base. Compared with the prior art, the device has the advantages that damage to the internal structure of the cochlea is reduced, operation efficiency is improved, and meanwhile, real-time measurement and control over implantation force in a stimulation electrode implantation process are achieved.

Description

technical field [0001] The invention relates to the technical field of cochlear implantation, in particular to a cochlear implantation device. Background technique [0002] Cochlear implantation is a conventional method for the treatment of deafness. The external speech processor converts the sound into a certain coded electrical signal, and directly stimulates the auditory nerve through the stimulating electrode implanted in the body to restore, improve and rebuild the auditory function of the deaf. The electrode is the most important functional part of the cochlear implant, which needs to be implanted into the patient's helical cochlear lumen. In today's minimally invasive cochlear implant surgery, the stimulating electrode can be directly implanted through a long and narrow drilling channel Into the inner cavity of the cochlea of ​​the patient, during the implantation process, the doctor needs to manually operate, but because the implantation force of the electrode cannot...
