Overview
The MAYO Dissecting & Surgical Scissors (Model S13047-14) are precision-engineered stainless steel instruments designed for controlled tissue separation, layer-by-layer dissection, and fine surgical manipulation in both academic research laboratories and clinical settings. As a straight-blade, blunt-blunt configuration scissor with a total length of 14.5 cm, this instrument adheres to classical MAYO geometry—featuring short, robust blades and elongated handles optimized for high-leverage cutting and tactile feedback during prolonged procedures. Constructed from premium-grade austenitic stainless steel (typically AISI 420 or equivalent), the scissors undergo rigorous passivation, electropolishing, and autoclave-compatible heat treatment to ensure corrosion resistance, dimensional stability, and biocompatibility per ISO 7153-1 and ASTM F899 standards. Their design prioritizes mechanical reliability over disposable alternatives, supporting repeated sterilization cycles without degradation in edge integrity or spring tension.
Key Features
- Blade Configuration: Straight, blunt-blunt tips — ideal for safe dissection of delicate tissues (e.g., fascia, adipose layers, neural sheaths) without accidental puncture or perforation.
- Optimized Ergonomics: 14.5 cm overall length balances reach and control; handle rings sized for standard gloved hand operation with textured surface finish for slip-resistant grip.
- Material Integrity: Fully hardened and tempered stainless steel with Rockwell hardness ≥52 HRC at blade edges; non-magnetic and MRI-safe per ASTM F2503.
- Reusability & Sterilization: Compatible with steam autoclaving (134°C, 3 min), ethylene oxide (EtO), and low-temperature hydrogen peroxide plasma methods — validated per ISO 17664 and AAMI ST79.
- Manufacturing Traceability: Each unit carries laser-etched batch identification and model code (S13047-14), enabling full quality traceability under ISO 13485-certified production protocols.
Sample Compatibility & Compliance
These MAYO scissors are routinely employed in rodent and large-animal surgical models, human cadaveric training, and histological specimen preparation. They exhibit consistent performance across soft biological matrices including muscle, connective tissue, vascular structures, and embryonic membranes. The blunt-blunt tip geometry complies with IEC 60601-2-57 requirements for non-penetrating surgical instruments used in minimally invasive and open procedures. All manufacturing processes conform to China’s YY/T 0287–2017 (equivalent to ISO 13485:2016) and are subject to periodic third-party audits by the National Medical Products Administration (NMPA). Device labeling meets UDI requirements per FDA 21 CFR Part 830 and EU MDR Annex I essential requirements.
Software & Data Management
As a manual, non-electronic surgical instrument, the RWD S13047-14 MAYO scissors do not incorporate embedded electronics, firmware, or software interfaces. However, their use is fully integrable into digitally managed surgical workflows: instrument tracking via RFID or barcode systems (e.g., in central sterile supply departments), integration into electronic surgical checklists (WHO Safe Surgery Checklist), and inclusion in digital inventory logs compliant with ISO 9001 and GLP documentation standards. Sterilization cycle data associated with these scissors can be recorded in validated autoclave monitoring systems supporting FDA 21 CFR Part 11-compliant audit trails.
Applications
- Academic Research: Rodent laparotomy, cranial window preparation, nerve isolation, organ harvesting (e.g., spleen, thymus, lymph nodes).
- Clinical Training: Simulation-based surgical education, suture practice, anatomical dissection labs, and competency assessment in veterinary and medical curricula.
- Pathology & Histology: Precise trimming of biopsy specimens, embedding block preparation, and gross tissue sectioning prior to microtome processing.
- Regulatory-Compliant Procedures: Used in GLP-compliant toxicology studies and GCP-aligned clinical trial support labs where instrument traceability and reprocessing validation are mandatory.
FAQ
Are these scissors suitable for ophthalmic or neurosurgical applications?
No — the 14.5 cm length and standard MAYO geometry are optimized for general dissection and medium-depth tissue work. Microsurgical applications require finer-tip, shorter-length instruments (e.g., Vannas or Castroviejo scissors).
What is the recommended reprocessing protocol between uses?
Follow AAMI ST79 guidelines: pre-cleaning at point-of-use, ultrasonic cleaning with enzymatic detergent, thermal disinfection ≥90°C, and steam sterilization at 134°C for 3 minutes. Inspect visually and functionally before each use.
Does RWD provide sterilization validation documentation for this model?
Yes — upon request, RWD supplies IFU documents, bioburden test reports, and sterilization compatibility summaries aligned with ISO 17664 and EN 285.
Can this model be customized with laser marking for institutional branding?
Yes — RWD supports OEM/ODM engraving services under NDA, including custom logos, department codes, or asset IDs, without compromising material integrity or sterility assurance.
