Its working principle is to convert sound signals into electrical signals and directly stimulate the auditory nerve, enabling patients to perceive sounds. A cochlear implant mainly consists of two parts: an external device and an implant body. External device: It includes a microphone, a speech processor, and a transmitter. The microphone receives sounds, the speech processor converts the sounds into digital signals, and the transmitter transmits the processed signals to the implant body through electromagnetic induction. The implant body includes a receiver, an electrode array, and a wire. The receiver receives the signals from the transmitter, converts them into electrical signals, and directly stimulates the auditory nerve through the electrode array. In order to better match the patient's ear condition, the microphone and the transmitter in the external device generally need to be customized according to the patient's head shape.

The sliding of the limiting post 301 in the reference sleeve 302 is controlled by the movement of the limiting mechanism 5.

[0047] Specifically: through the designed flexible limiting component 3, when welding the shell outside the cochlea, the cochlea shell can be pushed between a plurality of limiting posts 301. The stressed part of the limiting post 301 can slide downward under force. The downward-sliding limiting post 301 and the non-sliding limiting posts 301 can be combined into a limiting step groove, ensuring the clamping stability of the cochlea shell in the clamping seat 8. After controlling the sliding of the limiting post 301 through the limiting mechanism 5, the clamping and limiting of the flexible shell can be completed. Through the sliding cooperation of a plurality of limiting posts 301, the abutting and limiting effect on different special-shaped surfaces of the customized cochlea is improved, and the generation of welding errors is reduced;

[0048] Among them, the welding system 7 can be a corresponding laser welding device, and the circulating ventilation medium can be an inert gas and in a closed box or glove box, reducing welding oxidation products and avoiding the influence of the external environment on the welding quality.

[0049] Please refer to Figures 7 - 8 and Figures 10 - 11 As shown in, at least two connecting ventilation grooves 303 are provided at the top outside of the limiting post 301. A connecting tube 304 is connected to the inside of the connecting ventilation groove 303. The connecting tube 304 extends to the bottom of the limiting post 301 and is connected to a ventilation seat 305. A connecting nozzle 307 is provided at the bottom of the ventilation seat 305. The ventilation seat 305 is rotatably connected to the top of the air duct mechanism 6. The air duct mechanism 6 includes at least one air extraction part and a blowing part. The blowing and suction strokes of the connecting ventilation groove 303 are switched by the rotation of the ventilation seat 305 on the top of the air duct mechanism 6;

[0050] Both the ventilation seat 305 and the limiting post 301 are connected to the switching mechanism 2, and the rotation of the ventilation seat 305 and the limiting post 301 is driven by the switching mechanism 2;

[0051] The switching mechanism 2 includes a first electric push rod 201. The first electric push rod 201 is connected to the top of the base 1. The first electric push rod 201 extends into the same-column limiting posts 301 at corresponding positions through a through groove opened on the side wall of the clamping seat 8. One end of the telescopic part of the first electric push rod 201 is connected to a fixing plate 202, and both ends on one side of the fixing plate 202 are connected to rotating seats 203;

[0052] A rotating block 204 is rotatably connected to each of the two rotating seats 203. The other side of the rotating block 204 is hinged to a switching rod 205, and a plurality of transmission rods 206 are hinged to the bottom of the switching rod 205;

[0053] The other ends of the plurality of transmission rods 206 located at the top are hinged to a first driving ring 207, and the first driving ring 207 is sleeved outside the limiting column 301 at the corresponding position;

[0054] The other ends of the plurality of transmission rods 206 located at the bottom are hinged to a second driving ring 209, and the second driving ring 209 is connected to the outside of the rotating seat 203.

[0055] Specifically: when it is necessary to switch the positions of the ring limiting column 301 and the ventilation seat 305 at the top of the air duct mechanism 6, the first electric push rod 201 can be controlled to work to extend or shorten. The first electric push rod 201 can drive the fixed plate 202 to move. The fixed plate 202 can push the rotating block 204 to move through the rotating seat 203. The movement of the rotating block 204 can drive the switching rod 205 on the other side to move. The movement of the switching rod 205 can drive the transmission rods 206 on both sides to push the corresponding first driving ring 207 and second driving ring 209. The limiting column 301 and the ventilation seat 305 at the corresponding position are controlled to rotate through the first driving ring 207 and the second driving ring 209. When the ventilation seat 305 rotates, it can be switched to the air duct on the other side through the rotation of the bottom air outlet. The same column of multiple limiting columns 301 and the ventilation seat 305 can be driven to rotate synchronously through the control of the transmission rods 206 on both sides;

[0056] It is beneficial to switch the suction air duct direction of the ventilation slots 303 connected to the limiting columns 301 in different columns, so that the limiting columns 301 on both sides of the welding surface and the ventilation slots 303 form a convective heat dissipation effect. The heat accumulated in the peripheral area of the cochlear special-shaped surface can be quickly taken away through convective heat dissipation, improving the convective heat dissipation effect during the welding of the special-shaped surface, reducing the penetration of the cochlear housing due to insufficient heat dissipation, improving the welding heat dissipation effect of the soft material cochlear housing, and improving the welding stability;

[0057] At the same time, multiple limiting columns 301 can adjust the convective heat dissipation area according to the welding needs, improving the high adaptability to the special-shaped welding area of the cochlear housing, and being beneficial to improving the welding effect through flexible fitting and regional convective heat dissipation effect;

[0058] Furthermore, the multiple ventilation slots 303 outside the limiting column 301 can still keep the contact orientation with the surface of the cochlear housing corresponding after rotation to improve the convective heat dissipation effect. And the ventilation slots 303 located on the air suction side can suck the welding fumes and scraps and filter them through the air duct suction, improving the cleanliness of the contact position and avoiding the accumulation of fumes between the multiple limiting columns 301 affecting the cleanliness of the contact surface.

[0059] Among them, the stroke control of the first electric push rod 201 can be controlled by a PLC to ensure that the rotation strokes of the limit column 301 and the ventilation base 305 can enable the connecting nozzle 307 to switch the air duct. This part is well-known technology in the related field and will not be elaborated further;

[0060] Please refer to Figures 2 and Figure 3 , both sides of the inner cavity of the first drive ring 207 are connected with sliders 208, and the sliders 208 are slidably connected to the chutes opened on both outer sides of the limit column 301;

[0061] Specifically: Through the designed sliders 208 and chutes, the chute provided outside the limit column 301 enables the limit column 301 to slide outside the slider 208 when sliding, avoiding the sliding interference of the limit column 301 from affecting the rotational drive of the first drive ring 207.

[0064] Specifically: Through the designed air duct mechanism 6, when the ventilation base 305 rotates through the second drive ring 209, the connecting nozzle 307 at the bottom of the ventilation base 305 can be communicated with the corresponding communication nozzle 603 under the rotation stroke. At this time, the communication nozzle 603 and the connecting nozzle 307 can form a passage for exhaust or suction operations. The connecting nozzle 307 can press the energy absorption cover 309 through the energy absorption plates 308 on both sides, which is beneficial to the fully fitting of the retractable connecting nozzle 307 to the corresponding communication nozzle 603 after the stroke is switched, improving the connection tightness;

[0065] Among them, the communication nozzle 603 and the connecting nozzle 307 can be selected as self-closing nozzles to be in a closed state when not communicated, avoiding disturbing the heat dissipation air duct.

[0071] Specifically: through the designed limiting mechanism 5, when the second electric push rod 501 works and extends, it can drive the control main rod 502 to move. The movement of the control main rod 502 can drive a plurality of control support rods 503 to move. The movement of the control support rods 503 can drive the pressing plate 504 to move.
