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.
