Used artificial cochlea electrode battle array connection only has two kinds of structure types one is straight electrode battle array connection in the world at present, another
Kind is pre-bending electrode array connection, and there are also one is micro-bend electrode array connection.Since elastic force acts on after straight electrode implantation, cochlea cannot be held tightly
Current spread is caused on inner shaft side, and power consumption is big, influences effect of stimulation, and is easy to squeeze cochlea inner tissue, causes to damage to cochlea
Wound, and pre-bending battle array joins electrode since camber is too big, implantation is very inconvenient, is imported using supporting wire, after supporting wire extraction, can exist
Controlling when leaving a hole on electrode, and being implanted into bad can also damage cochlea.
There are three types of the contacts that used artificial cochlea electrode battle array connection uses in the world at present, and one is spherical shape, another kind is
Annular, there are also one is piece shapes.Spherical point contacts electrode array connection exposed area is small, and power consumption is big, stimulates insufficient.Ring contacts electrode
Battle array connection is whole circle stimulation, although exposed area is big, it is excited that it can cause the nerve other than auditory nerve to generate, and influences to stimulate
Purpose.Piece shape contact electrode battle array joins exposed area and is situated between spherical point contacts electrode array and ring contacts electrode array connection, and is not
Whole circle stimulation, effect of stimulation is good, small power consumption.The prior art is arc-shaped using piece shape contact battle array connection, contact, is adhered to silicon
Glue surface, is not buckled to, and is easy to fall off, and bottom be it is arc-shaped, directionality is bad when implantation, is easy to produce torsion, is not achieved
The purpose that effect is swashed to nearly modiolus direction, influences effect of stimulation.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of to return hook-shaped or U-shaped electrode contacts with sidewise hole, with
Colloidal silica combine it is stronger, bare area is more optimized, small power consumption, the micro-bend electrode of the sufficient artificial cochlea of electro photoluminescence.
To achieve the goals above, the technical solution of the utility model is as follows: a kind of micro-bend electrode of artificial cochlea, including according to
Secondary setting electrode leading portion, electrode middle section and electrode back segment, the electrode leading portion include the flexibility that electrode leading portion forefront is arranged in
Curved side several electrode contacts arranged at equal interval in electrode tip, micro-bend electrode, set gradually in micro-bend electrode excurvation side
One sounding mark, the second sounding mark and third sounding mark；The electrode middle section includes first the second boosting of boosting ring ring, electricity
The very thin spire of pole lead, contact conductor spire；The circuit that the electrode back segment includes loop electrode, is connect with loop electrode
Contact conductor, the stimulating electrode lead being connect with electrode contacts and deconcentrator, setting and electrode contacts add-back road electricity on deconcentrator
The consistent slot of number of poles, passes through for loop electrode lead and stimulating electrode lead；Entire micro-bend electrode is all molded by colloidal silica
Sizing.
Preferably, the electrode middle section further includes the fillet being arranged in direction signs and direction signs.
Preferably, the first falope ring and the second falope ring is arranged in the loop electrode both ends.
Preferably, the electrode contacts are back hook-shaped electrode, and the first sidewise hole and the second sidewise hole, bottom are arranged at go back to hook
It is connect by the first solder joint with stimulating electrode lead on the inside of portion.
Preferably, the electrode contacts are U-shaped electrode, and third sidewise hole and the 4th sidewise hole, bottom is arranged in U-shaped two sides
Inside is connect by the second solder joint with stimulating electrode lead.
The micro-bend electrode of artificial cochlea by adopting the above technical scheme, include at least the following beneficial effects:
One, minor bending electrode global shape combines two boosting rings and direction signs, more convenient in implantation process, right
Cochlea is small, and unnecessary distortion will not be integrally caused to electrode；
Two, the combination of the electrode contacts with sidewise hole and colloidal silica is stronger, not easily to fall off, electrode contacts exposed area
Properly, artificial cave reliability and the big raising of safety, it is ensured that implant electrode works normally for a long time in human body, to artificial
Cochlea manufacturing technology has impetus.
