As medical equipment continues to develop towards miniaturization, precision, and high performance, micro coaxial cable is becoming the preferred choice for an increasing number of medical device manufacturers. Particularly in high-end applications such as electronic endoscopes, surgical robots, and portable imaging equipment, micro coaxial cable, with its high-frequency transmission capability, excellent anti-interference performance, and superior flexible structure, greatly enhances the overall performance and reliability of medical equipment.
What is a micro coaxial cable束？
A very fine coaxial cable bundle is a high-frequency signal transmission cable with an extremely small outer diameter and highly precise structure. It is typically composed of a central conductor, an insulating layer, a woven shielding layer, and an outer sheath. Its wire diameter can be as thin as less than 0.2 mm. Compared with traditional parallel cables or multi-core cables, it has the following significant advantages:
Excellent signal integrity
Effectively suppress signal crosstalk and electromagnetic interference through coaxial structure, ensuring stable transmission of high-definition images and precise data.
Extremely flexible
Adaptable to complex space routing and multiple bending requirements, especially suitable for complex wiring environments inside minimally invasive medical devices.
Support high-frequency high-bandwidth transmission
Meet the needs of high-definition video, real-time imaging, and high-density signal transmission in high-bandwidth scenarios.
The core demand for ultra-fine coaxial cable束 in the medical field
With the accelerated progress of the intelligence and miniaturization of medical equipment, ultra-fine coaxial cable束 demonstrates significant advantages in the following typical scenarios:
Electronic endoscope
Small size and high resolution image transmission capability ensure doctors can achieve real-time, clear, and delay-free visual operations during surgery.
② Surgical robot
Multi-axis control and visual feedback systems require a large amount of high-speed signal transmission, and extremely thin coaxial cables can ensure high-frequency, high-speed, and stable signal transmission.
Portable imaging equipment
Ultrasonic diagnostic equipment and ECG monitors, etc., have higher requirements for the lightweight, flexible, and anti-interference capabilities of cables.
