Background

The artificial cochlea is an electronic bionic device developed according to the physiological principle of the cochlea, and is a multi-disciplinary high and new technology product combining medicine, biomedicine, audiology, materials science, microelectronics and mechanics. The artificial cochlea can replace the damaged auditory organ with pathological changes, the external speech processor converts the sound into an electric signal in a certain coding form and transmits the electric signal into the cochlea of the human body, and the electrode system implanted into the human body stimulates the auditory nerve fibers distributed in the electric signal, so that the auditory nerve is directly excited to recover or rebuild the auditory function of the deaf. The cochlear implant is one of the important achievements of modern medicine, and for severe or extremely severe deafness, the implantation of the cochlear implant is the only internationally recognized device which can recover the auditory sense of patients with bilateral severe or extremely severe sensorineural deafness.

The implantation process of the artificial cochlea is the implantation of the artificial ear. Cochlear implant is an important operation in the field of otology, and during cochlear implant, the processor of cochlear implant should be placed in the bone groove of temporal bone on the implanted side. It is particularly important to fully expose the temporal bone above and behind the mastoid without enlarging the incision behind the ear. In the process of manufacturing a bone bed of a receptor/stimulator by a cochlear implant electric drill for cochlear prosthesis surgery, the drill bit has extremely high rotating speed and is very sharp, and the drill bit is easy to slide in the operation process, so that a flap above a damaged bone groove is damaged, and the flap is hemorrhagic or even necrosed after surgery; in addition, because the deep light of the operation visual field is difficult to reach, and a large amount of bone powder is generated by an electric drill for drilling and grinding the skull, the operation visual field is poor, and the accuracy and the efficiency of the operation are seriously influenced. The current clinically used retractor equipment is a general surgery conventional retractor, has larger volume, is difficult to be effectively exposed in a limited operation space, and easily influences the visual field of a doctor; and the device does not have a synchronous attraction function and can be realized only by multi-hand operation.
