The invention discloses a split type fully-implanted artificial
cochlea system, which comprises a basic
implant and an implanted
speech processor, and is characterized in that the basic
implant receives a coding
signal of the implanted
speech processor,
decodes the coding
signal, generates an electrical stimulation pulse and stimulates
auditory nerves; the implantable
speech processor receives an external sound
signal, processes the sound signal, generates a coded signal and transmits the coded signal to the basic
implant; the implantable speech processor is detachably connected to one side of the basic implant; a connecting piece is arranged on the basic implant, a clamping hole is formed in the implantable speech processor, and when the implantable speech processor is connected to the basic implant, the connecting piece is clamped and embedded in the clamping hole; according to the split type fully-implanted artificial
cochlea system, when hardware of the speech processor needs to be upgraded or damaged, only minimally
invasive surgery is needed, and the implanted speech processor is taken out through the connecting piece, so that secondary
surgical injury is avoided, the safety is improved, and meanwhile, the use cost of a user is reduced.
