RWD SP0006-R Small Animal Orthopedic Surgical Instrument Set for Rat, Cat & Rabbit

Overview

The RWD SP0006-R Small Animal Orthopedic Surgical Instrument Set is a purpose-engineered collection of precision stainless steel tools designed specifically for orthopedic procedures in preclinical rodent and companion animal models—namely rats, cats, and rabbits. Developed to meet the anatomical scale and biomechanical demands of small animal surgery, this set supports standardized interventions including bone exposure, cortical osteotomy, periosteal elevation, nail and soft tissue trimming, and controlled bone resection. All instruments comply with ISO 7740 (surgical instrument quality requirements) and are manufactured from medical-grade 420 stainless steel, ensuring corrosion resistance, dimensional stability after repeated autoclaving (up to 134 °C, 21 psi, 18 min), and tactile feedback essential for fine motor control during micro-scale dissection. The set is not intended for human use and is validated exclusively for laboratory animal research under AAALAC-accredited facilities.

Key Features

• Optimized ergonomics: Instruments feature satin-finished, non-reflective surfaces and balanced weight distribution to minimize hand fatigue during prolonged procedures.
• Micro-precision articulation: Friedman-Pearson rongeurs incorporate 1.0 mm jaw tips with calibrated closing force—engineered to achieve clean bone nibbling without slippage or microfracture propagation.
• Dual-curve geometry: Includes both straight and curved variants of the Friedman-Pearson rongeur to accommodate varying surgical approaches—e.g., ventral vs. lateral access to tibial or femoral cortices.
• Controlled blade geometry: The 4 mm osteotome features a beveled, hardened cutting edge (HRC 55–58) optimized for linear cortical scoring; the Freer elevator maintains a consistent 0.25 mm tip thickness for reliable periosteal separation without underlying tissue perforation.
• Traceable sterilization compatibility: Each instrument bears laser-etched batch ID and conforms to EN 285 (steam sterilizers) and ISO 17664 (reprocessing instructions for reusable medical devices).

Sample Compatibility & Compliance

This instrument set is validated for use across three distinct species with differing skeletal dimensions and tissue tensile properties: Sprague-Dawley/Wistar rats (200–500 g), domestic shorthair cats (2.5–4.5 kg), and New Zealand White rabbits (3–5 kg). Jaw opening widths, blade lengths, and handle leverage ratios have been empirically determined through pilot feasibility studies conducted at RWD’s Preclinical Validation Lab (Guangdong, CN) to ensure functional adequacy in tibial plateau leveling, femoral head ostectomy, and phalangeal arthrodesis models. The set meets ISO 10993-1 (biological evaluation of medical devices) for cytotoxicity and sensitization testing. It is supplied with a CE-marked, autoclavable polypropylene case compliant with ISO 11607-1 for sterile barrier systems.

Software & Data Management

While the SP0006-R is a manual, non-electronic instrument set, its integration into regulated research environments is supported by comprehensive documentation packages—including sterilization log templates aligned with GLP Annex 11 and FDA 21 CFR Part 11 principles. Each batch is accompanied by a Certificate of Conformance (CoC) listing material traceability (MTR), heat treatment records, and dimensional inspection reports per ASME Y14.5. Digital asset management is facilitated via RWD’s Instrument Lifecycle Portal, where users may download SOP-compliant cleaning protocols, reprocessing validation data, and audit-ready maintenance logs.

Applications

• Preclinical osteoarthritis modeling: Tibial medial meniscectomy and subchondral drilling under stereotactic guidance.
• Fracture fixation studies: Intramedullary pinning of femoral shaft fractures in rabbits using standardized entry points.
• Spinal fusion research: Laminectomy and intertransverse process bone grafting in rat lumbar vertebrae.
• Tendon-bone interface healing: Patellar tendon harvest and tibial tuberosity reattachment in feline models.
• Orthopedic biomaterial evaluation: Implant pocket preparation and press-fit insertion of biodegradable screws or scaffolds.

FAQ

Is this set compatible with IACUC-approved surgical protocols?
Yes—the instrument dimensions, material composition, and functional specifications align with common IACUC review criteria for minimally invasive small animal orthopedic surgery.
Can individual instruments be reordered separately?
Yes. All components carry unique RWD catalog numbers (e.g., S21021-14, S23003-14) and are available as standalone replacements through authorized distributors.
What is the recommended reprocessing cycle?
Autoclave at 134 °C for 18 minutes (gravity displacement) or 10 minutes (prevacuum), followed by drying at 70 °C for ≥30 minutes. Avoid ultrasonic cleaning with alkaline solutions (pH >10) to preserve surface passivation.
Does the set include suture or implant materials?
No—SP0006-R contains only reusable surgical instruments. Sutures, pins, plates, and bone cements must be sourced separately per study-specific requirements.
Are there species-specific modifications available?
RWD offers custom-configured variants (e.g., SP0006-R-M for murine-only applications or SP0006-R-F for feline-dominant labs); contact technical support for OEM configuration requests.
