The invention discloses a cochlea pre-bending electrode array implanting device, which comprises a silica gel electrode array which is in the shape of cochlea under a non-elastic deformation, and theinner part of the silica gel electrode array is provided with a guide hole; a straight hard core wire is arranged in the guide hole, and the hard core wire supports the silica gel electrode array to be straight shape; the implanting device further comprises a substrate, a flexible piece and a connecting piece; the flexible piece comprises a fixing end and a flexible rod capable of performing stretching movement in relative to the fixing end; the fixing end is fixed on the substrate, and the flexible rod is connected with the silica gel electrode array; one end of the connecting piece is fixedwith the substrate and the other end is buckled with a hard core wire. The cochlea pre-bending electrode array implanting device solves the problems that the pre-bending electrode is required to implant by two hands and it is difficult to position the electrode and inconvenient to adjust position.
Description
technical field [0001] The invention relates to a device for implanting a medical electrode, in particular to a device for implanting a cochlear pre-bent electrode array. 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 stimulates the nerves through the electrode system implanted in the body to restore, improve and rebuild the auditory function of the deaf. Over the past two decades, with the development of high technology, cochlear implants have developed rapidly and have entered clinical application from experimental research. Cochlear implants are now used as a routine method for the treatment of severe deafness to total deafness all over the world. Cochlear implants are currently the most successful biomedical engineering devices. [0003] The pre-bent electrode itself is made into a cochlear form similar to the cochlear curvature. In...
