Abstract

The present invention discloses an expandable totally-implantable cochlear implant system. The system comprises a stimulation electrode, a stimulation unit, a plugging unit, a first expansion unit and a second expansion unit; the stimulation electrode comprises 16 to 24 contact electrodes and electrode wires connected with each contact electrode; the stimulation unit is connected with the stimulation electrode, the plugging unit, the first expansion unit and the second expansion unit and outputs stimulation signals to the stimulation electrode, so that the stimulation electrode directly outputs electrical stimulus; and the plugging unit includes a coil socket and a power source recovery module connected with the coil socket. According to the expandable totally-implantable cochlear implant system of the invention, a traditional cochlear implant system composed of two parts in vivo and in vitro respectively is improved to a totally-implantable cochlear implant; and when a sensing unit or a charging unit malfunctions, the expandable-totally implantable cochlear implant system can be connected with an in-vitro speech processor so as to continue to work properly, and the effectiveness of the system can be under double protection.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an expandable cochlear implant system. Background technique [0002] A cochlear implant is an electronic device that converts sound into electrical signals in a certain coded form by an external speech processor, and directly excites the auditory nerve through the electrode system implanted in the body to restore or reconstruct the auditory function of the deaf. There are tens of millions of patients with severe sensorineural deafness in the world, and cochlear implantation is currently the only way to regain hearing. [0003] However, the current cochlear implants are all divided into internal implants and external parts, which bring many inconveniences to users: the external parts are prone to collision and damage; daily life is inconvenient, and users cannot exercise vigorously; When swimming, you need to remove the external parts, but you can only return to the silent world; a...
