Description

一种人工耳蜗弯电极 An artificial cochlea curved electrode

技术领域 FIELD

[0001] 本发明涉及一种电极,特别涉及一种人工耳蜗弯电极。 [0001] The present invention relates to an electrode, particularly to a cochlear implant electrode bend.

背景技术 Background technique

[0002] 人工耳蜗是由耳蜗内的植入体、言语处理器、麦克风及传送装置所组成。 [0002] Cochlear implant is within the cochlea, speech processor, a microphone and a transmitting device composed. 声音由麦克风接收后转换成电信号再传送至言语处理器将信号放大、过滤,并由传送器传送到刺激器,产生的电脉冲送至相应的电极触点,从而刺激耳蜗内听神经产生兴奋并将声音信息传入大脑,产生听觉。 Sound converter into an electric signal received by the rear microphone longer be sent to the speech processor amplifies the signal filtered by the transmitter is transmitted to the stimulator, the electrical pulses generated to the respective contact electrodes to stimulate the cochlear nerve and generate excitement the sound information to the brain, resulting in hearing. 在整个人工耳蜗系统中,人工耳蜗电极是人工耳蜗植入体中非常重要的组成部分。 Throughout the cochlear implant system, the cochlear electrodes is a very important part of cochlear implants.

[0003]目前世界上所用的人工耳蜗电极分直电极和弯电极两大类,直电极不能做到近蜗轴刺激,弯电极植入不方便,在植入前如果不把电极张直是没法植入耳蜗内,所以国内外大都采用在电极阵联时预埋支撑内芯,通过一根直的支撑内芯把弯电极张直,手术时边插入边抽出支撑内芯,电极插入和支撑钢芯抽出要同步,电极插入过快容易损伤耳蜗或折弯支撑钢芯,电极插入过慢、支撑芯抽出过快容易使电极头勾回卡在耳蜗内无法再植入耳蜗内,由于支撑芯抽出后无法再插回电极内,电极无法再插入耳蜗,只能更换一套植入体去植入,导致手术中断,手术时间长,对耳蜗损伤加重;同时术中视觉效果也不好,看不清插入的具体状况,容易划破电极硅胶体及电极丝绝缘层,使电极短路;由于有支撑芯,电极阵列粗,很难做成纤细状,影响植入深度。 [0003] cochlear implant electrodes currently used in the world of sub-straight and curved electrode electrode two categories, direct electrode stimulation can not do nearly the worm shaft, curved electrode implantation is not convenient, if not before implanting the electrodes is not straight - method implanted in the cochlea, so that domestic and mostly using embedded core supported with the electrode array, by a straight inner core supporting the electrode sheets bent straight, surgery side insertion edge extracting the core support, and the support electrode insertion to synchronize drawn steel core, cochlear electrode is inserted too easily damaged or bent steel core support, the electrode is inserted too slowly, the support core out too easily tip hook back in the card can no longer cochlear implant cochlea, since the support core after extraction can not plug it back into the electrode, the electrode can no longer be inserted into the cochlea, only to replace a set of implants implanted, resulting in interrupted operation, long operation time, aggravation of cochlear damage; the same time intraoperative visual effect is not good, see pins inserted particular condition, and colloidal silica easily cut wire electrode insulating layer, short-circuiting electrode; support core due to the electrode array rough, difficult to make thin shape, affect implant depth.

[0004]目前世界上所用的人工耳蜗电极阵联采用的触点有三种,一种是球形,另一种是环形,还有一种是片形。 [0004] As used world contact with cochlear electrode array uses three, one is spherical, and the other is a ring, there is a sheet-shaped. 球形触点电极阵联暴露面积小,功耗大,刺激不充分。 Small spherical contact electrode array with the exposed area, power consumption, insufficient stimulation. 环形触点电极阵列是整圈刺激,暴露面积虽然大,但是它可能引起听觉神经以外的神经产生兴奋,影响刺激目的。 An annular contact electrode array is a full circle stimulation, while the exposed area is large, it may cause nerve outside the auditory nerve excitation, or stimulation purposes impact. 片形触点电极阵联暴露面积介与球形触点电极阵与环形触点电极阵联之间,且不是整圈刺激。 A sheet-shaped electrode array with the exposed contact area between the medium and the spherical contact electrode arrays associated with the annular contact electrode array, and not the whole Stimulation. 现有技术采用片形触点阵联,粘附在硅胶表面,表面积小,阻抗值高,容易脱落,电极丝焊接结构可靠性不高,焊点区电极丝没有缓冲,容易产生断路,使植入体失效。 Using the prior art sheet-shaped array with the contacts adhered to the surface of silica gel, surface area is small, a high impedance value, easy to fall off, the electrode wire welded structure reliability is not high, no cushion pad electrode wire zone, prone to breaking the plant into the body fail.
