RWD SP0007-R Rat Dissection Instrument Set

Overview

The RWD SP0007-R Rat Dissection Instrument Set is a purpose-engineered surgical toolkit designed for precise, reproducible soft-tissue dissection and neurovascular isolation in laboratory rats (typically 200–500 g). Built to meet the ergonomic and functional demands of in vivo rodent surgery—including stereotaxic procedures, peripheral nerve studies, spinal cord exposure, and organ harvesting—the set integrates high-carbon stainless steel instruments with calibrated tip geometry, optimized weight distribution, and autoclavable construction. Each component adheres to ISO 7153-1:2016 (surgical instruments — materials) and conforms to ASTM F899 standards for hardness, corrosion resistance, and edge retention. The kit supports both acute terminal procedures and survival surgeries under IACUC- or AAALAC-accredited protocols, with all instruments validated for ≥500 sterilization cycles via saturated steam at 134 °C.

Key Features

• Precision-engineered fine-tip instruments including IRIS Fine Scissors (straight and curved, 10.5 cm) for delicate tissue separation without crush artifact
• Metzenbaum dissecting scissors (straight and curved, 14.5 cm) with blunt-blunt tips for safe fascial plane development and adipose tissue clearance
• Spencer suture removal scissors (narrow-profile, 11 cm) enabling controlled suture cut without adjacent tissue trauma
• Halsted mosquito hemostats (straight and curved, 12.5 cm) featuring 2.0 mm jaw width and micro-serrated tips for secure vessel occlusion and traction
• Olsen-Hegar needle holders (12 cm) with integrated cutting blades—designed for efficient suture passage and trimming during microvascular anastomosis
• IRIS 1×2 toothed tissue forceps (10 cm) offering minimal grip-induced ischemia during neural or vascular manipulation
• ALM 4×4-tooth retractor (7 cm,钝 tip) for stable, low-pressure tissue retraction during thoracic or abdominal exposure
• Stainless steel microvascular clips (6 × 1 mm, 15 mm length) and dedicated clip applicator (14 cm) compatible with transient vessel occlusion in cerebral or renal microsurgery
• Included absorbable PGA suture (5-0, ½-circle needle, pre-attached) certified to USP Class VI biocompatibility standards

Sample Compatibility & Compliance

The SP0007-R set is validated for use in Sprague-Dawley, Wistar, and Long-Evans rat strains across common experimental paradigms: craniotomy, dorsal laminectomy, carotid artery cannulation, intracranial tumor implantation, and orthotopic organ transplantation. All instruments are compatible with standard autoclave cycles (134 °C, 3 bar, 5–10 min), ethylene oxide gas sterilization, and hydrogen peroxide plasma systems. The kit complies with GLP documentation requirements for instrument traceability (batch-coded handles), and supports audit-ready recordkeeping per FDA 21 CFR Part 58 and OECD Principles of Good Laboratory Practice. No latex, phthalates, or PVC components are present.

Software & Data Management

While the SP0007-R is a manual instrumentation system, its design enables seamless integration into digital surgical workflows. Each instrument is labeled with laser-etched model codes (e.g., S12005-10, F12010-11) compatible with institutional inventory management platforms (e.g., LabVantage, Quartzy). RWD provides downloadable PDF-based instrument logs, sterilization cycle tracking templates, and IACUC-compliant maintenance checklists—available via secure customer portal access. Optional QR-code-labeled instrument trays support RFID-enabled usage logging for longitudinal procedural analytics in large-scale preclinical studies.

Applications

• Intracerebral hemorrhage modeling via stereotactic collagenase injection (requiring precise dural incision and cortical exposure)
• Sciatic nerve chronic constriction injury (CCI) with controlled epineurial dissection using curved Metzenbaum scissors and 1×2 toothed forceps
• Renal artery clamp-induced ischemia-reperfusion injury (leveraging microvascular clips and retractors for suprarenal exposure)
• Carotid artery thrombosis induction using FeCl₃-mediated injury and real-time flow assessment
• Orthotopic glioblastoma xenograft implantation requiring sterile cranial window preparation and dural suturing
• Spinal cord injury models (T9–T10 laminectomy) utilizing Myrtle probes and spinal retractors for controlled dural opening

FAQ

Is this set suitable for mouse surgery?
The SP0007-R is optimized for rats; for mice (Mus musculus, 20–35 g), RWD recommends the SP0005-M Mouse Dissection Set, which features scaled-down tip geometries and reduced instrument lengths.
Are replacement parts available individually?
Yes—each component carries a unique RWD catalog number (e.g., S12005-10, F12010-11) and is stocked for direct reorder through authorized distributors or RWD’s global fulfillment centers.
Does the set include sterilization validation documentation?
RWD provides a Certificate of Conformance (CoC) with each shipment, listing material certifications, hardness test results (≥55 HRC), and bioburden limits (<1 CFU/unit) per ISO 11737-1.
Can the instruments be used in MRI or PET environments?
All instruments are non-magnetic austenitic stainless steel (AISI 316L), fully compatible with 3T and 7T MRI scanners and do not interfere with PET radiotracer imaging.
What is the expected service life under routine lab use?
With proper cleaning (EN ISO 15883-compliant washer-disinfectors), sharpening (when required), and autoclave maintenance, average instrument lifespan exceeds 3 years in high-throughput academic core facilities.
