A clean, unhindered signal transmission is crucial to the success of advanced surgical tools like the RF ablation devices, endoscopes, and surgical scalpels. A lost video signal or a stray control signal can negate all accuracy in a surgical procedure. Selection of a dependable coaxial cable assembly is not simply a technical decision—it is a patient safety decision. Through dedicated R&D and precision manufacturing, Hotten Electronic Wire Technology provides coaxial assemblies for surgical environments that meet precise requirements.
Coaxial cable assemblies carry high frequency signals without a significant amount of noise or interference as compared to a standard wiring solution. Coaxial design helps maintain video and electrosurgical signal fidelity in surgical instruments—such as an endoscopic camera—or the ICE (Intracardiac Echocardiography) cable. Our coaxial assemblies feature a central conductor, high-performance dielectric insulation, and multiple shielding layers to block EMI from monitors, diathermy and other electrosurgical devices or overhead lighting for stable, real time visualization.
Signal Integrity Under Sterilization: Surgical cables need to survive regular autoclaving, gamma radiation, or chemical cleaning without degrading electrical performance. Hotten uses medical-grade dielectric materials that maintain their electrical integrity throughout hundreds of sterilization cycles.
Flexibility Without Fracture:The coaxial cables found on endoscopic devices are bent, twisted, and manipulated throughout a procedure. Our coaxial assemblies use fine-stranded conductors and durable but flexible shields to survive tens of thousands of flex cycles while keeping the cable from failing or the signal from attenuating.
Biocompatibility and Safety:Any coaxial assembly that will come in contact with the patient is required to meet ISO 10993 guidelines. We use non-toxic jackets and lead-free solder in all our medical coaxial assemblies to eliminate cytotoxicity risk.
The research and development team at Hotten creates over 300 different cable configurations each year, including unique coaxial assemblies for the following applications:
RF Ablation Cables:Coaxial designs that can safely and precisely transmit the high-voltage RF signals while keeping the temperature feedback signal pristine.
Endoscope and Ultrasound Probe Cables:Thin coaxial bundles (sometimes as small as 34 AWG) that transmit high-frequency video and echo signals with extremely low attenuation.
Surgical Scalpel Cables:Hybrid assemblies that pass activation and power signals through coax elements and filter electrosurgical noise.
EEG Lead Wires and Dental Sensing Cables:Low-noise coaxial configurations designed to prevent electrical artifact and ambient noise.
All configurations are validated using a network analyzer to check impedance matching (typically 50Ω or 75Ω) and return loss specifications.
Our over 10,000㎡ of workshop space and more than 40 production units produce over 144+ million meters of cable—annually. Every single medical-grade coaxial assembly is subjected to the following tests:
Hi-pot and insulation resistance testing to ensure the patient and operator are protected.
Shielding effectiveness measurement across frequencies from low to 3 GHz (relevant for endoscopic video).
Flex and torsion cycle testing equivalent to typical surgical conditions.
Every stage of manufacturing, from conductor stranding to connector overmolding, is verified by our quality team. With this thorough procedure Hotten's coaxial assemblies can be installed straight out of the box without any problems.
Deep R&D Capability: Our specialty medical cable engineers work collaboratively with device manufacturers to configure coaxial assemblies that are highly tunable for impedance, attenuation and flex life.
Rapid Customization: Within two to three weeks, Hotten can have fully functioning prototypes of specialty coaxial assemblies for detailed evaluation prior to beginning production.
Supply Chain Reliability: The 144 million meters of cable manufactured per year give Hotten the capability to respond to demand and complete orders from pilot production through mass production without hesitation.
RF ablation systems, endoscopes, ultrasound probes, and surgical scalpels are all sensitive to the performance of the coaxial cable assemblies. These medical-grade coaxial cables are developed by Hotten for demanding surgical applications. They supply constant signal, can be sterilized to a high standard and, when being repeatedly bent, case after case, they maintain reliable performance under repeated flexing. Insist on Hotten if you require absolute, unwavering signal integrity and the the highest level of reliability for your surgical devices.
