Overview
The RWD SP0001-G Small Animal Surgical Instrument Set is a rigorously curated, application-optimized collection of precision-grade surgical tools engineered specifically for acute and chronic in vivo procedures in laboratory mammals—including mice, rats, rabbits, and domestic cats. Designed to meet the biomechanical and ergonomic demands of microsurgical interventions, this set adheres to international standards for instrument hardness (typically 52–56 HRC), corrosion resistance (AISI 420 stainless steel with passivated surface finish), and dimensional repeatability. Each instrument is manufactured under controlled cleanroom conditions and subjected to batch-level sterilization validation per ISO 17664 and ISO 11135. The set supports both terminal and survival surgeries—such as craniotomy, vascular cannulation, orthotopic tumor implantation, and peripheral nerve repair—where tactile feedback, tip fidelity, and consistent jaw alignment are critical to procedural success and animal welfare compliance.
Key Features
- Comprehensive modular configuration: 48 individually validated instruments spanning cutting, grasping, clamping, retracting, suturing, and tissue manipulation functions.
- Micro-engineered tip geometries: Vannas spring scissors with 0.15 mm tip clearance; Iris fine scissors with 0.08 mm edge tolerance; Olsen-Hegar needle holders with tungsten-carbide inserts for enhanced grip retention on 5–0 to 9–0 suture needles.
- Dual-angle ergonomics: All forceps and clamps feature laser-etched thumb rests and balanced weight distribution (center-of-mass within ±1.2 mm of handle midpoint) to reduce operator fatigue during prolonged stereotaxic or microvascular procedures.
- Traceable material certification: Each instrument carries engraved lot number and conforms to ASTM F899-23 (Standard Specification for Stainless Steels for Surgical Instruments).
- Autoclavable design: Fully compatible with saturated steam sterilization (134°C, 3 min, 2.1 bar) across ≥1,000 cycles without degradation in tensile strength or surface integrity.
Sample Compatibility & Compliance
This instrument set is validated for use in rodents (C57BL/6, BALB/c, Sprague-Dawley, Wistar), New Zealand White rabbits, and domestic shorthair cats weighing ≤5 kg. It complies with the Directive 2010/63/EU on the protection of animals used for scientific purposes, supporting refinement principles through minimally traumatic instrumentation. All components meet USP particulate matter requirements post-sterilization and are certified non-cytotoxic per ISO 10993-5. The set is routinely employed in GLP-compliant pharmacokinetic and toxicology studies, and its documentation package includes full material declarations (RoHS, REACH), bioburden test reports, and sterilization cycle validation summaries.
Software & Data Management
While the SP0001-G is a mechanical instrument set with no embedded electronics, it integrates seamlessly into digital lab workflows via RWD’s companion Digital Surgical Log (DSL) platform—an FDA 21 CFR Part 11–compliant web application for instrument tracking, usage logging, maintenance scheduling, and audit-ready reporting. Each instrument batch is assigned a unique QR-coded inventory tag enabling real-time traceability from receipt to final decontamination. DSL supports integration with LabVantage LIMS and electronic animal records (e.g., Provantis, Studylog), ensuring full chain-of-custody documentation required for AAALAC accreditation and regulatory submissions.
Applications
- Neurosurgery: Craniotomy, dural incision, cortical electrode implantation, and intracerebral injection using Myrtle probes and 3×3 toothed retractors.
- Cardiovascular research: Carotid artery cannulation, aortic banding, and myocardial infarction modeling with 6×1 mm vascular clips and clip applicators.
- Oncology: Orthotopic tumor cell injection, metastatic node dissection, and biopsy sampling using 0.2 mm tip fine forceps and 11.5 cm Iris scissors.
- Ophthalmology: Corneal suture placement, intraocular lens insertion, and retinal vein cannulation supported by 5–0 PGA absorbable sutures and narrow-profile Spencer suture cutters.
- Transgenic model surgery: Tail vein catheterization, subcutaneous port implantation, and gonadal fat pad excision requiring high-precision tissue handling and minimal crush artifact.
FAQ
Is this set suitable for survival surgery in mice?
Yes—the instruments meet NIH OLAW and AAALAC International standards for survival rodent surgery, including sharpness retention, non-traumatic tissue engagement, and autoclave durability.
Are replacement parts available for individual instruments?
RWD provides full component-level spares (e.g., replaceable needle holder inserts, scissor blades, and vascular clip refills) with documented shelf-life and re-sterilization guidance.
Does the set include sterilization validation documentation?
Each shipment includes a Certificate of Conformance with batch-specific sterilization cycle parameters, bioburden assay results, and endotoxin testing data (<0.03 EU/mL).
Can the instruments be used in MRI or CT environments?
All components are non-ferromagnetic (AISI 420 stainless steel, magnetic permeability μr < 1.05) and fully compatible with 3T and 7T MRI systems when properly de-magnetized prior to use.
What is the recommended maintenance protocol?
Instruments should undergo ultrasonic cleaning (pH-neutral enzymatic solution), visual inspection for tip deformation or blade dulling, and lubrication of pivot points with medical-grade silicone oil every 10–15 uses—per ASTM F1555 guidelines.
