Description

Technical Field

[0001] This utility model relates to the field of endoscope cable technology, specifically to an anti-interference endoscope cable. Background Technology

[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It contains an image sensor, optical lens, light source, and mechanical devices, and can be inserted into the stomach through the mouth or other natural orifices. Endoscopes can visualize lesions that X-rays cannot, making them extremely useful for doctors. During use, endoscopes typically transmit signals via connecting cables.

[0003] Based on the above, the inventors have discovered the following problems: When current endoscope cables are connected and used, the connection between the endoscope cable and the connector lacks an anti-interference mechanism. When the endoscope cable and connector are transmitting signals, the signal transmission between the cable and the connector is easily affected by electromagnetic interference, power supply interference and other factors, resulting in unstable signal transmission and affecting the use effect of the endoscope.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an anti-interference endoscope cable in order to achieve a more practical purpose. Utility Model Content
