Overview
The RWD SP0003-R Microsurgical Instrument Set is a purpose-engineered collection of high-precision stainless steel instruments designed specifically for delicate microsurgical procedures in small animal models—including rats, cats, and rabbits. Engineered for reproducibility and tactile fidelity under magnification (e.g., stereo microscopes or surgical loupes), this set supports critical applications such as neurovascular anastomosis, peripheral nerve repair, corneal transplantation, and orthotopic tumor implantation. Each instrument conforms to ISO 7153-1:2016 (Surgical Instruments — Metallic Materials — Part 1: Stainless Steels) and undergoes rigorous passivation per ASTM A967 to ensure biocompatibility, corrosion resistance, and long-term dimensional stability after repeated autoclaving (134 °C, 3 bar, 18 min cycles). The ergonomic design prioritizes low-force actuation and tip stability—essential for minimizing tissue trauma during sub-millimeter dissection and suture placement.
Key Features
- Full set includes 12 core instruments: fine iris scissors (straight and curved), Olsen-Hegar needle holders, Vannas spring scissors (straight and curved), Halsted mosquito hemostats (straight and curved), ultra-fine straight forceps (0.2 mm tip), stainless steel microvascular clips (6 × 1 mm), clip applicator, 12-0 nylon suture with 3/8-circle needle, #3 scalpel handle, and #11 blades.
- All cutting and grasping surfaces are hand-honed to ≤0.1 µm surface roughness (Ra) and electropolished for enhanced smoothness and reduced protein adhesion.
- Stainless steel components are fabricated from ISO-certified AISI 420B martensitic stainless steel (hardness: 52–55 HRC), optimized for edge retention and resistance to pitting in saline-rich biological environments.
- Clip applicator features a calibrated ratchet mechanism enabling consistent 0.5–1.0 N clamping force—critical for maintaining vessel patency without intimal damage during microvascular bypass.
- Instrument lengths (8.5–14 cm) are selected to balance maneuverability in confined surgical fields and operator fatigue reduction during prolonged procedures (>2 h).
Sample Compatibility & Compliance
This set is validated for use across common rodent and companion animal surgical models requiring sub-millimeter precision. It supports standardized protocols compliant with NIH Guide for the Care and Use of Laboratory Animals and AAALAC International accreditation requirements. Instruments are compatible with standard autoclave cycles (including pre-vacuum and gravity displacement), ethylene oxide sterilization, and hydrogen peroxide plasma systems. All components meet EU Medical Device Regulation (MDR 2017/745) Class I criteria for non-invasive, reusable surgical instruments. Documentation includes material traceability (heat lot numbers), sterilization validation summaries, and ISO 13485:2016 manufacturing certification from RWD’s Guangdong-based facility.
Software & Data Management
While the SP0003-R is a manual mechanical instrument set (no embedded electronics), it integrates seamlessly into GLP- and GCP-compliant workflows through RWD’s optional Digital Lab Logbook™ platform. Users may assign unique QR-coded asset tags to each instrument tray, enabling audit-ready tracking of sterilization history, usage frequency, and maintenance logs. The system supports 21 CFR Part 11–compliant electronic signatures and automated expiration alerts for sterilization cycles—ensuring full traceability required for regulatory submissions to FDA, EMA, or PMDA.
Applications
- Microvascular anastomosis in rat femoral artery/vein models (standardized for ischemia-reperfusion studies)
- Sciatic nerve crush/transection and epineurial repair in rabbit tibial nerve models
- Carotid artery cannulation and intracranial injection in mouse and rat neurosurgery
- Ocular surgery including limbal stem cell transplantation and intraocular lens implantation in feline models
- Orthotopic pancreatic or mammary tumor engraftment with minimal collateral tissue disruption
- Telemetry transmitter implantation with precise fascial layer separation
FAQ
Is this set suitable for primate or porcine microsurgery?
The SP0003-R is optimized for animals ≤5 kg. For larger species, RWD recommends the SP0005-L series with extended-length instruments and higher-torque needle holders.
Are replacement parts available separately?
Yes—individual items (e.g., #11 blades, 12-0 sutures, vascular clips) are cataloged under RWD’s consumables line with bulk ordering options and lot-specific CoA documentation.
What is the recommended cleaning protocol prior to sterilization?
Immediate enzymatic soak (pH 7.0–7.5, 2% w/v protease) followed by ultrasonic cleaning (40 kHz, 5 min) and thorough rinsing with deionized water is required to prevent biofilm formation on micro-textured surfaces.
Does RWD provide training or SOP templates for this set?
RWD offers downloadable GLP-aligned SOPs (including instrument inspection checklists and sharpening guidelines) via its Technical Resource Portal, accessible with registered lab credentials.
