When the entire endoscope system needs four paths of light paths for transmitting illumination light, image signals, control reception signals and transmission signals in alignment, and communication light modules are required to be simultaneously placed on both sides of the processor for an endoscope and the connector for an endoscope, the first communication device 110 and the second communication device 210 of the present endoscope system are flexibly installed, and thus, the limitation on the layout of the entire system is small.

It should be further noted that, with the enhancement of image quality and the continuous improvement of image rate to 4k image quality, the transmission of high-speed electric signals (such as 10 Gbps) has great technical difficulties, such as EMC problems, signal integrity, long-distance transmission problems, etc., so that the use of communication modes is greatly limited, and the requirements on the alignment accuracy of image signals are very strict. And because the whole endoscope system adopts four paths of light paths of illumination light, image signals, control receiving signals and sending signals to align and transmit, the alignment precision is difficult to ensure after multiple plugging and unplugging, and meanwhile, the multipath optical communication also has interference on high-speed image signal transmission, so that the design of the whole integration level is poor.

Compared with the transmission of high-speed electric signals (such as 10 Gbps), the first signal collimator 123 and the second signal collimator 222 of the endoscope system communicate through collimation light alignment, so that the simultaneous contactless transmission function of image signals and control signals is realized, the transmission mode of the signal collimator for the optical signals is not influenced by long transmission distance and electromagnetic interference, the signal collimator has stronger anti-interference capability and transmission efficiency, and the requirement of high-speed image transmission in the medical field is met.

Because the wireless power supply portion 130 and the wireless power receiving portion 230 are both annular structures, a smaller cross-sectional size can be occupied compared to a wireless power supply structure of a pancake coil design of a face-to-face power supply structure, so that the structure of the entire endoscope system is more compact. Meanwhile, due to the annular wireless power supply structure, compared with a wireless power supply structure designed by a pancake coil, the diameter is larger, so that the surface area is larger, the heat dissipation effect is better, and the endoscope system with higher power supply requirement can be adapted.

It should be noted that, since the quality of the image of the endoscope product is continuously improved to 4k resolution (e.g. the speed of 10 Gbps), the resources of the image processing circuit are also continuously improved, and the power supply requirement of the endoscope product is also improved. By matching the wireless power supply part 130 and the wireless power receiving part 230 of the annular structure of the endoscope system, the endoscope system not only can meet the requirement of higher power supply, but also can be integrated with other light, gas and signal transmission interfaces to be of a more compact design, and the structure of the whole endoscope system is also more compact and has high space utilization rate; meanwhile, the heat dissipation effect is better, and the holding hand feeling of a user is better.

The TEC radiator includes: the heat dissipation device comprises a cold-face substrate, a plurality of TECs (semiconductor refrigeration materials) and a hot-face substrate, wherein heat is transferred from the cold-face substrate to the hot-face substrate through forced direct current, so that a heat dissipation function is achieved. The heat conducting member 161 is connected with a cold-face substrate of the TEC radiator, and a hot-face substrate of the TEC radiator is connected with the first fixing frame 140.
