4. Currently, the electrode array in cochlear implant damages the inner wall of cochlea during the insertion process into cochlea, causing permanent damage to hearing. Many existing technologies can solve the problem that the inner wall of a cochlea is damaged in the process of inserting an electrode array into the cochlea, but all the technologies can cause the complexity of the electrode array structure, increase the cost of the electrode array, and have unobvious practical effects.

The two springs C47 in the power supply mechanism 40 are in a compressed state, and the inclined surfaces a45 on the two copper contacts a44 are in electrical contact with the inclined surfaces B49 on the corresponding copper contacts B48, respectively. The cleaning rod 24 in the headset 4 is at a distance from the headset hole 5, the spring B26 is in a compressed state and the shift lever 19 is in contact with the inclined surface C21 on the driving block 20.
If the two copper contacts A44 and the corresponding copper contacts B48 in the power supply mechanism 40 are corroded due to electric corrosion, the corrosion between the copper contacts A44 and the copper contacts B48 due to electric corrosion can be effectively cleaned through the reciprocating plugging power supply mechanism 40.
During the process of inserting the power supply mechanism 40 into the slot A7, the inclined surfaces a45 on the two copper contacts a44 and the inclined surfaces B49 on the corresponding copper contacts B48 slide in a staggered manner, the two copper contacts a44 are retracted into the corresponding copper sleeves B42 under the action of the inclined surfaces B49 of the corresponding copper contacts B48, and the springs C47 are further compressed. The relative sliding between the copper contact a44 and the copper contact B48 can effectively scrape the electro-corrosion generated on the contact surface of the copper contact a44 and the copper contact B48, and the fallen corrosion falls onto the power socket 53.
During the process of pulling the power mechanism 40 out of the slot A7, the two copper contacts a44 gradually disengage from the corresponding copper contacts B48 and slide a certain distance out of the copper bush B42 under the action of the corresponding springs C47. When the power mechanism 40 is completely pulled out of the slot A7, the falling rust on the power socket 53 can be effectively cleaned by the blower or the brush.
When the electro-corrosion rust on the copper contact A44 and the copper contact B48 is cleaned up, the power supply mechanism 40 is inserted into the slot A7 again, and the two copper contacts A44 on the power supply mechanism 40 inserted into the slot A7 are respectively kept in good electrical contact with the corresponding copper contacts B48.
If the corrosion is generated between the contact pin 12 in the socket mechanism 8 and the copper sleeve A34 in the plug mechanism 31 due to the electric corrosion generated during long-time operation, the plug mechanism 31 is firstly pulled out from the socket mechanism 8, so that the contact pin 12 is separated from the copper sleeve A34. Then, the sliding sleeve 17 on the seat body 9 of the socket mechanism 8 is pressed, the sliding sleeve 17 drives the cleaning plate 14 to move axially through the guide rod 16, the scraping hole 15 of the cleaning plate 14 effectively scrapes the electric corrosion rust on the surfaces of the five pins 12, and the spring a18 is further stretched. When the pressing force on the sliding sleeve 17 is removed, the cleaning plate 14 is reset axially under the reset action of the spring A18 and drives the sliding sleeve 17 to reset through the guide rod 16, the reset of the cleaning plate 14 scrapes and cleans the surfaces of the five contact pins 12 again, and the electric corrosion rust on the surfaces of the five contact pins 12 on the socket mechanism 8 can be effectively scraped and cleaned by reciprocating for a plurality of times.
In the process of pressing the sliding sleeve 17 of the socket mechanism 8 on the earphone 4 in a reciprocating manner, the sliding sleeve 17 drives the cleaning rod 24 to effectively clean dust and dirt accumulated in the earphone hole 5 of the earphone 4 through the deflector rod 19 and the driving block 20, and the spring B26 expands and contracts in a reciprocating manner. When the pressing force applied to the slide bushing 17 of the jack mechanism 8 of the earphone 4 is removed, the cleaning rod 24 is returned by the return action of the spring B26.
After the contact pins 12 of the socket mechanism 8 finish the electro-corrosion rust cleaning, the plug mechanism 31 is plugged onto the socket mechanism 8 in a reciprocating manner, the five contact pins 12 of the socket mechanism 8 can effectively clean the inner walls of the corresponding copper bush A34 on the plug mechanism 31, and the cleaned inner walls of the copper bush A34 fall into the cover cap 35.
After the inner wall of the copper bush a34 of the plug mechanism 31 is cleaned, the cap 35 is unscrewed to remove falling rust, and then the cap 35 is screwed on again, and finally the plug mechanism 31 is inserted into the socket mechanism 8 again.
When the electrode array 2 on the implant 1 needs to be inserted into the cochlear meatus, the elastic rod 3 is inserted into the hollow electrode array 2 first, so that the electrode array 2 is changed from a vortex state to a straight state. Then, the electrode array 2 embedded with the elastic rod 3 is inserted into the cochlear meatus, and the elastic rod 3 is slowly drawn out of the electrode array 2 along with the penetration of the electrode array 2 into the cochlear meatus during the insertion process.
As shown in fig. 3, as the electrode array 2 enters the cochlear meatus and the elastic rod 3 is pulled out, the elastic coefficient of the electrode array 2 gradually increases from the end to the implant 1, the elastic coefficient of the elastic rod 3 inserted into the electrode array 2 gradually increases from the end of the electrode array 2 to the implant 1, and the average value of the elastic coefficient of the elastic rod 3 is greater than the average value of the elastic coefficient of the electrode array 2, so that the electrode array 2 gradually undergoes vortex bending to adapt to the cochlear meatus without damaging the inner wall of the cochlear meatus in the process of gradually entering the cochlear meatus under the action of the elastic rod 3.
When the electrode array 2 is completely inserted into the cochlea, the elastic rod 3 is just pulled away from the electrode array 2.
In conclusion, the beneficial effects of the invention are as follows: the electrode array 2 implanted into the subcutaneous implant 1 is made of hollow silica gel material matched with the elastic rod 3, and the electrode array 2 can be inserted into the cochlea without damage under the matching of the elastic rod 3, so that permanent damage to the inner wall of the cochlea caused by the electrode array 2 in the process of inserting into the cochlea is avoided.
In the invention, the copper contact A44 in the power supply mechanism 40 can scrape and clean the rust or dust generated by electric corrosion on the corresponding copper contact B48 on the earphone 4 when the power supply mechanism is installed, so that the effective electric connection between the copper contact A44 and the corresponding copper contact B48 is ensured, and further, the chip in the earphone 4 is ensured not to be damaged due to current pulse caused by unstable electric connection between the copper contact A44 and the copper contact B48.
In the invention, before the socket mechanisms 8 on the ear-hang phone 4 and the emitter are in plug-in fit with the plug mechanisms 31 at two ends of the data line 36, rust or attached dust formed by electric corrosion on the surfaces of the pins 12 can be scraped and cleaned, so that the good fit of the socket mechanisms 8 and the plug mechanisms 31 is ensured, and the electric conductivity of the socket mechanisms 8 and the plug mechanisms 31 after being plugged in is ensured.
In the invention, dust accumulated in the headset hole 5 of the headset 4 can be synchronously cleaned when the contact pin 12 in the socket mechanism 8 on the headset 4 is cleaned, thereby ensuring the smoothness of the headset hole 5 and ensuring the effective receiving of the inner vibration film 29 to sound.
