EndoSpine Spinal endoscope 5.3MM 6.3MM 7.3MM 8.4MM 10.0MM full-endoscopic spine surgery

QuNaMai Spinal Endoscopy System — Engineered by the Manufacturer, Backed by Clinical Education

In minimally invasive spine surgery, optical clarity isn’t just about vision—it’s about safety, precision, and confidence.
QuNaMai is not a distributor. We are the original manufacturer of high-performance spinal endoscopes, designing and producing every component in our own ISO 13485-certified facility.

Our spinal endoscope series (available in 5.3mm, 6.3mm, 7.3mm, 8.4mm, and 10.0mm outer diameters) supports a full range of approaches—including PTED, interlaminar, and UBE (Unilateral Biportal Endoscopy)—across cervical, thoracic, and lumbar levels. Each scope features:

High-resolution optics with true-color reproduction
Anti-fog coating and deep depth-of-field for stable visualization
Optimized working channel compatibility with RF probes, drills, and graspers
Reusable models (autoclavable) and sterile single-use options

But we go beyond hardware. As a manufacturer deeply engaged in clinical practice, QuNaMai operates its own hands-on training center, equipped with:

OR-grade simulation labs
Fresh-tissue and synthetic spine models
Live HD broadcast systems for real-time teaching
Full sets of QuNaMai endoscopy systems and instruments

We offer structured courses in UBE, PELD, cervical key-hole decompression, and more—led by experienced spine surgeons. Training focuses on:

Safe portal placement and trajectory planning
Complication avoidance and management
Instrument handling and team coordination
Standardized procedural workflows

Our training is education-first—no sales pressure, no hidden obligations. Surgeons from academic hospitals to community practices are welcome to learn, practice, and validate techniques in a realistic environment.

Through our direct B2B2C digital platform, we serve hospitals and surgeons worldwide with:

Transparent pricing (no middlemen)
Customization options (view angle, length, connector type)
Rapid technical support and clinical feedback loops
Integrated solutions: devices + consumables + education

QuNaMai — From our factory to your OR, and into the training lab, we’re with you at every step of your minimally invasive journey.

Choose QuNaMai not just as a supplier—but as a trusted manufacturing partner who builds, trains, and stands behind every product we deliver.
