Laryngoscope
The core components of the laryngoscope include the laryngoscope blade, handle, light source/lens base and optical fiber positioning bracket. Manufactured from biocompatible materials such as medical-grade 316L stainless steel, titanium alloy and PEEK, they are suitable for clinical operations such as endotracheal intubation, featuring both precise adaptability and tolerance to high-frequency disinfection.
| Part Name | Material | Core Machining Parameters | Clinical Adaptation Value |
| Laryngoscope Blade (Speculum) | Medical Grade 316L Stainless Steel / Titanium Alloy | Dimensional Tolerance ±0.005 mm; Surface Roughness Ra 0.1 μm; Curvature Accuracy ±0.01°; Tip Fillet R0.2 mm | Prevents mucosal scratches, fits the physiological curve of the pharynx and larynx, and maintains shape after high-frequency disinfection |
| Laryngoscope Handle | 7075 Aluminum Alloy (Anodized) / PEEK | Geometric Tolerance ≤0.003 mm; Ergonomic curved surface in grip area; Thread Fit Tolerance 6H/6g | Lightweight and corrosion-resistant, reliable sealing of the battery compartment, no loosening after multiple insertions and extractions |
| Light Source / Lens Base | Medical Grade Titanium Alloy | Concentricity ≤0.002 mm; Aperture Tolerance H7; Sealing Groove Accuracy ±0.001 mm | Ensures stable transmission of light and images, suitable for high-temperature and high-pressure disinfection |
| Optical Fiber Positioning Bracket | Titanium Alloy / Medical Grade POM | Groove Width Tolerance ±0.002 mm; Perpendicularity ≤0.003 mm | No optical fiber deviation, uniform illumination, improves the clarity of glottis observation |
General Machining and Quality Inspection Standards
Material Compliance:
Complies with ISO 10993 biocompatibility requirements. 316L stainless steel and titanium alloy must undergo passivation treatment to prevent heavy metal leaching.
Precision Assurance:
Adopts 4-axis/5-axis CNC machining. Key dimensions are 100% inspected by Coordinate Measuring Machine (CMM), with a defect rate ≤ 0.3%.
Surface Treatment:
Electropolishing + passivation. Resistant to high-pressure steam sterilization at 134℃ for ≥ 1000 cycles without rusting.
Assembly Compatibility:
Consistent thread fit tightness, insertion and extraction force controlled at 5–8 N to avoid operational jamming.
