In modern minimally invasive surgery, flexible endoscopic surgical robot systems are redefining the precision and safety of procedures in urology, pulmonology, and other natural orifice surgeries. Zamenix, an advanced flexible endoscopic surgical robot, integrates AI‑powered features such as respiratory synchronization, stone size guidance, and path recording to maximize surgical precision, safety, and efficiency. However, whether the robotic system can truly realize these advanced capabilities largely depends on its "eye"-the camera module at the tip of the endoscope. It needs to be slim enough to pass through natural orifices, sharp enough to identify stone textures and mucosal details, wide enough to eliminate blind spots, and durable enough to withstand the humid internal environment.
A miniature separate endoscope camera module with a diameter of just 3.0mm, supporting smooth 720P HD video, a 121.5° ultra‑wide angle, IP67 waterproofing, a Type‑C interface, and UVC driver‑free connectivity, can be perfectly embedded into Zamenix's flexible endoscope tip. It provides the robot with high‑quality, low‑latency, low‑distortion real‑time imaging, giving AI algorithms the most reliable visual input. The camera module's diameter, resolution, field of view, waterproof rating, and interface compatibility directly determine the surgical robot's perception capability and operational precision.
What Kind of Camera Does a Flexible Endoscopic Surgical Robot Need?
Unlike traditional rigid endoscopes, flexible endoscopic surgical robots enter the body through natural orifices (urethra, digestive tract), imposing extremely demanding requirements:
Extreme Miniaturization: Must pass through cavities of only 3‑4mm diameter; camera diameter must be ≤3.0mm.
High‑Definition Real‑Time Imaging: Must clearly identify stone surface textures, polyp borders, and mucosal congestion; 720P (1MP) is the baseline.
Ultra‑Wide Field of View: Covers a larger area within a narrow cavity, reducing probe movement and missed detections.
Waterproof and Moisture‑Resistant: The body is filled with fluids and irrigants; IP67 or higher is required.
Bend‑ and Kink‑Resistant: The camera must work reliably as the endoscope bends; a steel sheath provides necessary strength.
Plug‑and‑Play Compatibility: Seamless connection to the robot console, surgeon's display, and mobile devices; UVC driver‑free simplifies integration.


What Defines a Surgery‑Optimized Camera Module?
Based on our understanding of medical endoscopes and precision imaging, a Separate Endoscope module truly suited for Zamenix achieves precise alignment across diameter, imaging, field of view, protection, and interface.
3.0mm Ultra‑Fine Diameter + Steel Sheath IP67 Waterproof: Smooth Access to Narrow Cavities
Natural orifices such as the urethra, ureter, and bronchi have limited diameters. The endoscope insertion part must be very slim. This 3.0mm Diameter camera module features a Steel Sheel (steel sheath) with an outer diameter of only 3.0mm, easily embedding into Zamenix's flexible endoscope tip to reach deep into the renal pelvis and ureter. IP67 Waterproof makes it fully sealed, tolerating immersion at 1 meter for 30 minutes, resisting urine, irrigants, and blood. Post‑operative cleaning and disinfection are also easier. The steel sheath provides sufficient bending strength, protecting internal precision components during repeated flexing of the endoscope.
720P HD Imaging (1MP): Clearly Revealing Stone Textures and Mucosal Details
The surgical robot needs to identify stones, polyps, tumors, and other targets in real time to guide fragmentation, resection, or biopsy. Blurry images can cause AI algorithms to misjudge, increasing surgical risks.
This 720P Camera Module (also an HD Camera Module) features a 1MP CMOS sensor, outputting 1280×720 (720P) HD resolution at 30fps. At typical working distances of 3‑10mm, it clearly shows:
Crystal texture, size, and shape of stones
Polyp pedicles, margins, and surface vessels
Mucosal congestion, edema, ulcers, and abnormal growths
Precise grasping of tissue by biopsy forceps
720P@30fps ensures smooth, blur‑free video during dynamic movements (breathing‑induced tissue motion, instrument passage), providing a stable visual foundation for AI features like respiratory synchronization.
121.5° Ultra‑Wide Angle (Wide Angle Camera Module): Expanding View, Reducing Blind Spots
When the flexible endoscope is bent, the camera's field can become limited. An ultra‑wide angle covers a wider area of the cavity wall without increasing probe diameter. This module features a 121.5° diagonal ultra‑wide angle (97.2° horizontal × 73° vertical), with distortion controlled within -30% (acceptable for such a wide endoscope lens). Advantages:
At 5mm distance, covers approximately 10‑12mm laterally, effectively showing the full cavity.
Distortion is kept low; edge images are not excessively stretched, ensuring accuracy in stone size estimation and distance judgment.
Paired with the robot's path recording, the wide‑angle view helps the system construct a more complete intracavity map.
Fixed Focus (5‑50mm): Focus‑Free, Concentrate on Surgery
During surgery, the camera‑to‑tissue distance is relatively stable at 5‑50mm. A fixed‑focus design eliminates any focusing operation, reducing probe complexity and avoiding missed critical frames due to focus delays. With an F5.5 aperture and sufficient depth of field, the image remains sharp even when the endoscope bends or wiggles slightly.
Type‑C Interface + UVC Driver‑Free: Plug‑and‑Play with Multiple Terminals
Zamenix's control system may run on Windows/Linux, and surgeons may also need to view the feed on an iPad or phone. This module uses a Type‑C interface with built‑in UVC Camera Module driver‑free protocol, supporting USB Camera Module plug‑and‑play. Advantages:
Reversible plug: Type‑C simplifies connection, no orientation worry.
Plug‑and‑play: Connect to the robot host, surgeon's display, or mobile devices (Android/iPad) without driver installation.
Low latency: 720P@30fps real‑time transmission ensures sync between instrument manipulation and image.
Flexible deployment: Display on the console while wirelessly sharing to teaching or consultation scenarios.


Application Scenarios: From Urology to Pulmonology
1. Flexible Ureteroscopy for Stone Fragmentation: The robot navigates the endoscope into the renal pelvis; the 3.0mm ultra‑fine camera transmits real‑time stone images. AI uses stone size guidance to automatically estimate volume, assisting the surgeon in selecting optimal energy parameters. The 121.5° ultra‑wide view simultaneously observes both anterior and posterior walls of the renal pelvis, reducing blind spots. Respiratory synchronization stabilizes the画面 during breathing, reducing collateral damage.
2. Bronchoscopic Biopsy: For peripheral pulmonary nodule localization, 720P HD with ultra‑wide angle clearly shows subsegmental bronchial openings and mucosal abnormalities, guiding biopsy forceps for precise sampling.
3. Urinary Tract Tumor Diagnosis: Early bladder tumors may be only a few millimeters; high‑definition imaging detects flat lesions or carcinoma in situ. The robot's path recording function marks suspicious areas for follow‑up.
4. Mobile Teleconsultation: Surgeons view the robot's endoscope feed on a tablet via Type‑C direct connection without driver installation, guiding operations at primary hospitals.
Building a Reliable "Precision Eye" for Flexible Endoscopic Surgical Robots
Zamenix's core value lies in "maximizing surgical precision, safety, and efficiency through AI features." Adding a 3.0mm diameter, 720P HD, 121.5° ultra‑wide angle, IP67 waterproof steel‑sheathed, Type‑C UVC driver‑free miniature separate endoscope camera module gives the robot a truly professional "eye." Surgeons can confidently perform lithotripsy, biopsy, and resection under a clear, wide‑angle view, while AI algorithms make accurate judgments based on stable, high‑quality images.
