I. Introduction: The "Nerves and Blood Vessels" of Medical Devices​

In the rapidly evolving field of medical technology, ​micro-coaxial cables​ (with millimeter-scale diameters and exceptional signal transmission capabilities) have become the "invisible arteries" of modern medical equipment. From minimally invasive surgeries to remote monitoring, and from high-definition imaging to intelligent diagnostics, these tiny cables enable precise, miniaturized, and smart healthcare through efficient data transmission.

II. Medical Application Scenarios of Micro-Coaxial Cables​

1.Minimally Invasive Surgery and Interventional Therapy In neurosurgery, cardiovascular, and orthopedic procedures, micro-coaxial cables guide catheters to precisely locate lesions while transmitting real-time instrument positioning, physiological signals, and imaging data. Examples include:
Neurosurgery: Used in deep brain stimulation for Parkinson’s disease, transmitting electrode signals to external devices to assist doctors in regulating neural activity. ​
Cardiovascular Interventions: During coronary stent placement, cables help position guidewires in narrowed blood vessels and provide real-time feedback on blood flow parameters.
2.Medical Imaging Equipment​ CT, MRI, and ultrasound systems rely on micro-coaxial cables to transmit high-resolution images. Examples:
Magnetic Resonance Imaging (MRI): Cables maintain stable signal transmission in strong magnetic fields, ensuring image clarity. ​
Endoscopy: Integrated into endoscopes, cables enable real-time HD video transmission, enhancing precision in minimally invasive surgeries. ​
Surgical Robots and Smart Devices​

3.Surgical robots use cables to receive operator commands and feedback tactile signals. Examples:
Da Vinci Surgical System: Cables connect robotic arms to control systems, achieving sub-millimeter operational accuracy. ​
Portable Monitors: Cables transmit patient vital signs to cloud platforms, enabling remote diagnostics. ​
4.Implantable Medical Devices​
In devices like pacemakers and neurostimulators, cables require ​biocompatibility​ and long-term stability:
Cardiac Pacemakers: Cables link electrodes to pulse generators, ensuring precise electrical signal delivery. ​
Brain-Machine Interfaces (BMI): Cables record brain signals and transmit them externally, aiding paralyzed patients in achieving mind-controlled prosthetics.

III. Technical Advantages: Why Medical Technology Relies on Micro-Coaxial Cables​

Miniaturization: Diameters as small as 0.1–1 mm, suitable for endoscopes and catheters. ​High-Frequency Signal Fidelity: Center conductors as thin as tens of microns support GHz-level transmission, reducing imaging delays. ​Flexibility and Durability: Resistant to bending and torsion, adaptable to complex in-body environments. ​Biocompatibility: Made from platinum, titanium alloys, or ISO 10993-certified materials to minimize rejection risks.

IV. Future Trends: The "New Infrastructure" of Smart Healthcare​

Higher Transmission Speeds: Support 5G-enabled healthcare and real-time AI diagnostics, with bandwidth demands exceeding 40 Gbps. ​Intelligent Integration: Combine with sensors and AI chips for autonomous device decision-making (e.g., auto-adjusting pacemaker parameters). ​Biodegradable Materials: Develop temporary implantable cables that dissolve post-surgery, eliminating secondary procedures. ​Expansion of Telemedicine: Enable low-latency transmission for home monitoring and remote robotic surgery.
