Medical Endoscope

Infection control + high-speed imaging

With stricter infection control, disposable endoscopes are becoming the clinical standard. Circon provides reliable, well-protected, fast-delivered connectors to help manufacturers match top-tier quality.

Overview

COVID-19 and tighter regulation have accelerated single-use devices. Disposable endoscopes now support HD/UHD imaging and extend from diagnostics to therapeutic procedures, with per-use cost lower than reprocessing. We offer high-speed imaging, sealed protection and multi-sterilization compatibility across GI, respiratory, ENT and urology.

Market Drivers

Infection control: FDA/NMPA recommend single-use in high-risk scenarios
Imaging advances: single-use scopes now support HD / UHD
Cost-effective: per-use cost below reprocessing
Diverse clinics: GI / respiratory / ENT / urology

成功案例 / Success Cases

A Disposable Bronchoscope OEM

挑战 / Challenge：The disposable bronchoscope needed reliable connectivity within a tight cost target, while carrying 4K imaging signals and illumination power, plus ISO 10993 biocompatibility.

方案 / Solution：Deployed a custom plastic 2P 8-contact solution integrating signal and power contacts, using disposable-grade PPSU housing and precision injection-molded sealing.

成果 / Result：60% lower per-use cost vs. metal alternatives; passed full ISO 10993 biocompatibility panel.

A GI Endoscope Imaging Integrator

挑战 / Challenge：The system required 8-channel high-speed imaging from scope handle to host (> 8Gb/s aggregate), with strict crosstalk (< -30dB) and insertion loss targets.

方案 / Solution：Selected B-series 12-contact metal connector with custom impedance matching (50Ω/75Ω), optimized contact layout and grounding shield.

成果 / Result：Measured crosstalk < -35dB, insertion loss < 0.5dB, stable UHD imaging, passed customer's system-level validation.
