Description
Technical field
The present invention relates to a kind of electrode, particularly a kind of artificial cochlea's cranked electrode.
Background technology
Artificial cochlea is comprised of i-coch implant, speech processor, mike and transporter.Sound converts the signal of telecommunication to and is resent to speech processor by signal amplification, filtration after being received by mike, and be sent to stimulator by conveyer, the electric pulse producing is delivered to corresponding electrode contacts, thereby stimulates acoustic nerve in cochlea produce excited and import acoustic information into brain, produces audition.In whole artificial cochlea system, artificial cochlea electrode is very important ingredient in artificial cochlear implant.
At present artificial cochlea electrode used divides straight electrode and the large class of cranked electrode two in the world, straight electrode can not accomplish that nearly modiolus stimulates, cranked electrode is implanted inconvenient, if be not to implant in cochlea electrode Zhang Zhi before implantation, so mostly adopt pre-buried support inner core when electrode array joins both at home and abroad, by a straight support inner core cranked electrode Zhang Zhi, during operation, insertion limit in limit is extracted out and is supported inner core, electrode inserts and supports steel core and extracts out synchronous, electrode inserts too fast easy damage cochlea or steel core is supported in bending, electrode inserted slow, supporting-core is extracted out and too fastly easily to be made electrode tip hook to be back stuck in cochlea to replant in cochlea, owing to cannot turning back to again in electrode after supporting-core extraction, electrode cannot insert cochlea again, more transducer set implant goes to implant, cause operation to be interrupted, operating time is long, Cochlea is increased the weight of, in art, visual effect is also bad simultaneously, does not see the concrete situation of insertion, easily scratches electrode colloidal silica and wire electrode insulating barrier, makes electric pole short circuit, owing to there being supporting-core, electrod-array is thick, is difficult to make very thin shape, affects implantation depth.
The contact of artificial cochlea electrode battle array connection employing used has three kinds in the world at present, and a kind of is spherical, and another kind is annular, and also having a kind of is sheet shape.Spherical point contacts electrode array connection exposed area is little, and power consumption is large, stimulates insufficient.Annular contact electrode array is that whole circle stimulates, although exposed area is large, it may cause that the nerve generation beyond auditory nerve is excited, and impact stimulates object.Between sheet shape contact electrode battle array connection exposed area Jie joins with spherical point contacts electrode array and annular contact electrode battle array, and not that whole circle stimulates.Prior art adopts sheet shape contact battle array connection, sticks to Silica Surface, and surface area is little, and resistance value is high, easily comes off, and wire electrode Welding Structure reliability is not high, and solder joint region electrode silk is buffering not, easily produces and opens circuit, and implant was lost efficacy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of convenience and is connected with implanting instrument, good visual effect while implanting cochlea, and the convenient artificial cochlea's cranked electrode that is implanted to human body cochlea.
To achieve these goals, technical scheme of the present invention is as follows:
