3.9mm OV6922 AV Bronchoscope Module

This 3.9mm Miniature Wide Angle Waterproof Endoscope Camera Module with 4 High Brightness LEDs, featuring a 1/18-inch image sensor at its core, is specifically designed for minimally invasive medical endoscopic applications such as bronchoscopy and intubation. It delivers clinical-grade imaging performance within an extremely compact form factor. Measuring 3.9mm in diameter and 20.0mm in length, it features a stainless steel shell and waterproof construction for direct integration onto medical endoscope tips. This design accommodates insertion into confined spaces like airways and body cavities. Featuring a 98° diagonal field of view and a 10–60mm focus range, it achieves optimized optical focusing at a 20mm working distance—precisely matching practical airway observation distances for sharp, detailed tissue visualization. With 200 TV lines resolution, it meets clinical image clarity requirements. Four high-brightness white LEDs provide illumination down to 0 lux, eliminating external light sources while maintaining clear cavity visibility. A signal-to-noise ratio exceeding 48dB effectively suppresses image noise, ensuring purity and readability in dark-field imaging. Utilizing NTSC analog video output with 2:1 interlaced scanning and internal synchronization stability, it supports automatic gain control and a wide auto-exposure range of 1/60 to 1/170000 seconds. Combined with 0.45 gamma correction, it automatically optimizes image performance across varying lighting conditions. Operating voltage: 3–5V; power consumption: only 0.1–0.4W. Compatible with multiple medical host power systems, featuring low heat generation during prolonged use and high device stability. Operating temperature: 0°C–40°C; humidity: 30%–40% RH, fully matching routine clinical operating environments. Centered on miniaturized design, clinically adapted imaging, and high stability, this module delivers plug-and-play, clear, and reliable front-end imaging support for minimally invasive procedures such as airway visualization and intubation guidance in respiratory medicine.

Application of Endoscope Camera Module◢

1. Clinical Bronchoscopy Diagnostics: As the core imaging module for bronchoscopes, it penetrates deep into the narrow lumens of human bronchi and airways. Its 98° wide field of view combined with precise mid-to-close-range focusing capabilities clearly displays airway tissue morphology, providing intuitive imaging evidence for clinical diagnosis of airway inflammation, hyperplasia, and other pathologies in respiratory medicine.

2. Emergency and Routine Tracheal Intubation: Featuring a 3.9mm ultra-micro diameter steel structure design, it meets minimally invasive intubation requirements. Its 0lux low-light imaging capability clearly displays the airway intubation path in environments without additional light sources, assisting medical personnel in achieving precise intubation while enhancing procedural efficiency and safety.

3. Minimally Invasive Airway Intervention: Its precise imaging capability within a 10–60mm focal range clearly captures the location and morphology of minute foreign bodies or localized lesions within the airway. This provides real-time visualization support for interventional procedures such as minimally invasive airway foreign body removal and localized lesion management, reducing the invasiveness of diagnostic and therapeutic interventions.

4. Portable Medical Endoscope Accessories: Featuring low power consumption (0.1–0.4W) and a wide voltage supply range (3–5V), it meets the power requirements of portable endoscopic devices. Its compact structure (D3.9×L20.0mm) enables integration into miniaturized medical endoscopes, making it suitable for airway observation in mobile medical scenarios such as rapid outpatient airway screening and pre-hospital emergency care.
