Problems solved by technology

In the past, it took a lot of time to grind the bone groove and bone bed during cochlear implantation, and because of scalp traction, exposure of dura mater, lack of lighting, postoperative subcutaneous infection, skin flap necrosis, etc., cochlear implantation Most of the surgical complications of surgery result from this step

Embodiment

[0035] Please refer to figure 1 , the present embodiment provides a cochlear implant 10, which includes an external machine 100 and an implant body 200 implanted in the ear.

[0036] see figure 2 , the external unit 100 is left outside the body for detachable installation on the outer ear and behind the ear, wherein the detachable method is, for example, clamping, bonding, and binding, etc., and in this embodiment, clamping is preferred. The external unit 100 includes a processor 101 and a head piece 102. In order to facilitate clamping, optionally, the shape of the processor 101 in the external unit 100 is a crescent shape matching the outer ear, which is convenient for installation on the auricle.

[0037] read on figure 1, the processor 101 is provided with an audio collection module 110 and a speech processor 120 , and the headpiece 102 is provided with a data transmission system 130 .

[0038] Among them, the speech processor 120 is the core of the cochlear implant 10...

Abstract

The invention relates to an artificial cochlea and belongs to the medical instrument field. A component of the artificial cochlea implanted in a human body is called an implant, the implant includes areceiver / stimulator matched with a mastoid cavity, a flexible electrode sequence, a fixing member and a coil, the electrode sequence includes an electrode used for being inserted into a round windowregion to stimulate cochlear nerves, the receiver / stimulator is connected with the electrode sequence, the fixing member is connected with the receiver / stimulator, and the fixing member is attached toa bone wall of the mastoid cavity to fix in the mastoid cavity. The artificial cochlea is advantaged in that the receiver / stimulator can be implanted directly into the mastoid cavity, the electrode stretching out of the mastoid cavity can be inserted directly into the round window region, operation of grinding a cochlear implant to obtain a bone bed for placing the receiver / stimulator and a bonegroove for placing the electrode on the surface of a temporal bone during implantation is omitted, surgery efficiency is greatly improved, and some common complications of the cochlear surgery are avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cochlear implant. Background technique [0002] The cochlea is an important and irreplaceable structure on the human hearing receptors, and a considerable number of hearing loss patients have lesions in the cochlea. Cochlear implants are the ultimate method to save this part of hearing loss patients, and provide hearing compensation for hearing loss patients. [0003] Because the temporal bone is a flat bone, the acceptor / stimulator of the cochlear implant in the prior art is in the shape of a round cake, which is beneficial to implanting it in the middle region of the temporal bone body (close to the squamous part). When implanting the acceptor / stimulator, it is necessary to first After contouring the mastoid part, the bone bed for receiving / stimulator implantation and the bone socket for electrode placement were milled backward in the temporal bone. In the past, it took a lot...
