MAYO-NOBLE Wide-Profile Anatomical Scissors (Straight/Blunt–Blunt, 17 cm and Curved/Blunt–Blunt, 17 cm)

Overview

MAYO-NOBLE Wide-Profile Anatomical Scissors are precision-engineered surgical instruments designed for controlled tissue dissection, blunt separation, and delicate handling of soft biological structures in both academic research laboratories and clinical settings. These scissors operate on a classic lever-based mechanical principle, delivering consistent cutting force with minimal hand fatigue during prolonged procedures. The wide-profile handle design enhances grip stability and torque transmission, while the blunt–blunt tip configuration ensures non-penetrating manipulation—critical for dissecting fragile tissues such as adipose layers, fascial planes, or neural sheaths without unintended perforation. Manufactured by RWD (Shenzhen), a vertically integrated medical device producer compliant with ISO 13485:2016 quality management standards, each pair undergoes rigorous dimensional verification, surface finish inspection, and functional testing prior to sterilization and packaging.

Key Features

• Wide-profile ergonomic handles with textured matte-finish stainless steel surfaces for enhanced tactile control and reduced slippage under gloved conditions
• Blunt–blunt tip geometry optimized for atraumatic tissue spreading, blunt dissection, and vessel isolation without compromising structural integrity
• Two configurations available: straight (S13031-17) for linear access and precise directional control; curved (S13032-17) for improved visibility and maneuverability in confined anatomical spaces
• 17 cm total length balances reach and dexterity—compatible with standard surgical tray layouts and autoclave cycles (134°C, 3 min, Class B)
• Fully passivated 420 stainless steel blades with Rockwell hardness of HRC 52–55, ensuring long-term edge retention and resistance to pitting corrosion in saline and enzymatic environments
• Seamless joint construction with precision-ground pivot pin and calibrated tension adjustment for consistent blade alignment across repeated sterilization cycles

Sample Compatibility & Compliance

These scissors are validated for use across murine, porcine, and human cadaveric specimens in histology, neuroanatomy, cardiovascular physiology, and orthopedic research workflows. They comply with ISO 7740-1:2021 (surgical instrument nomenclature), ISO 8601:2004 (sterilization compatibility labeling), and GB/T 25982-2010 (Chinese national standard for surgical scissors). All units are supplied non-sterile and intended for terminal sterilization via steam autoclaving (EN 285), ethylene oxide (ISO 11135), or low-temperature hydrogen peroxide plasma (ISO 14937). Documentation includes full traceability to raw material lot numbers, heat treatment records, and biocompatibility test reports per ISO 10993-1 (cytotoxicity, sensitization, irritation).

Software & Data Management

As a manually operated mechanical instrument, MAYO-NOBLE Wide-Profile Anatomical Scissors do not incorporate embedded electronics, firmware, or software interfaces. Their operational integrity is independent of digital systems—ensuring uninterrupted functionality in electromagnetic-sensitive environments (e.g., MRI suites, electrophysiology labs) and eliminating cybersecurity or regulatory validation burdens associated with Class IIa+ connected devices. However, RWD provides downloadable digital asset packages—including 3D STEP files (for integration into surgical planning platforms), high-resolution photogrammetry models, and PDF-based IFU documentation aligned with FDA 21 CFR Part 820 and EU MDR Annex I essential requirements—for institutional inventory management and GLP/GMP-compliant recordkeeping.

Applications

• Dissection of superficial and deep fascial layers in musculoskeletal and plastic surgery training modules
• Isolation of peripheral nerves and vascular bundles during rodent neurovascular studies
• Preparation of intact organ blocks (e.g., heart, lung, kidney) for ex vivo perfusion or cryosectioning
• Trimming and shaping of hydrogel scaffolds and decellularized matrices in tissue engineering protocols
• Handling of delicate embryonic or neonatal tissues where sharp-tip instruments pose unacceptable risk of microtrauma
• Supporting standardized operating procedures (SOPs) compliant with OECD TG 407 (repeated-dose toxicity) and AAALAC International facility accreditation criteria

FAQ

Are these scissors suitable for sterile human surgical use?
Yes—when terminally sterilized per validated protocols and used within their defined shelf life, they meet ISO 13485 and EN 13795-1 requirements for critical medical devices.
What is the recommended maintenance protocol between uses?
Rinse immediately after use with deionized water, clean ultrasonically in enzymatic solution (pH 7.5–8.5), inspect pivot function and tip alignment under 10× magnification, and lubricate pivot point with medical-grade silicone oil before autoclaving.
Can the blades be resharpened?
No—blunt–blunt tips are not sharpened and must retain their original geometry; resharpening would compromise the atraumatic design intent and void compliance certification.
Do you provide OEM labeling or custom packaging for institutional procurement?
Yes—RWD supports private-labeling, multi-language IFUs, and ISTA 3A-compliant shipping cartons for global distribution partners and academic core facilities.
Is there a warranty or replacement policy for manufacturing defects?
All units carry a 24-month limited warranty covering material and workmanship defects under normal usage and proper sterilization conditions, with documented failure analysis provided upon return.
