Key Links in Medical Equipment R&D: Guide for Performance Evaluation of Ultra-Fine Coaxial Cable Assemblies

In the research and development phase of medical equipment, the stability of signal transmission is directly related to the performance and safety of the equipment. Especially for devices such as ultrasound diagnosis, endoscopes, and minimally invasive surgical robots, there is a high demand for high-speed and high-precision data transmission. The extremely thin coaxial cable (Micro Coaxial Cable) with its small diameter, high flexibility, and excellent shielding performance has become an indispensable key component in medical equipment. However, if performance evaluation is neglected during the research and development stage, it may lead to issues such as signal interference, image delay, and insufficient service life, thereby affecting the reliability and clinical performance of the equipment.

The importance of ultra-fine coaxial cable bundles in medical equipment

Medical device development requires a balance between signal integrity, device miniaturization, and long-term stability. Ultra-thin coaxial cables can achieve high-speed, low-loss signal transmission within limited spaces, while also having excellent anti-interference capabilities and good bending performance. This makes them particularly suitable for medical applications that require high-density wiring and complex mechanical operations. Early attention to cable performance can effectively avoid issues such as signal delay, image instability, or rapid cable wear in the later stages of development, ensuring the reliability of the device from design to clinical use.

Key Points for Evaluating the Performance of Ultra-Fine Coaxial Beam

The evaluation of harness performance should cover multiple dimensions such as electrical, mechanical, environmental, and electromagnetic compatibility (EMC). In terms of electrical performance, attention should be paid to impedance control, insertion loss, and return loss to ensure the complete transmission of high-speed signals. In terms of mechanical performance, bending radius, flexibility, and durability directly affect the operational flexibility of miniaturized medical equipment. In terms of environmental adaptability, the harness must be resistant to high temperatures, chemical corrosion, and have good biocompatibility to cope with sterilization and special usage scenarios. In terms of EMC performance, an excellent shielding structure can reduce the impact of electromagnetic interference on weak signals, ensuring stable image and data transmission.

Three, testing and optimization methods in the research and development stage

In the research and development phase, the combination of simulation and actual measurement methods can be used for comprehensive verification of ultra-fine coaxial cable bundles. By using a vector network analyzer to evaluate high-frequency characteristics, performing dynamic bending life tests, and conducting multiple bending and disinfection experiments in a simulated surgical environment, it can approach the real usage conditions more closely. This multi-dimensional verification can not only discover potential problems in advance but also optimize the cable design and routing scheme, thereby enhancing equipment stability, extending service life, and reducing maintenance costs.
