RWD SP0009-M Mouse Surgical Instrument Set

Overview

The RWD SP0009-M Mouse Surgical Instrument Set is a purpose-engineered, sterile-ready collection of high-precision microsurgical tools designed specifically for murine in vivo procedures—including stereotactic surgery, craniotomy, vascular cannulation, neural implantation, and soft-tissue dissection. Each instrument conforms to ISO 7153-1:2016 (Surgical Instruments — Metallic Materials — Part 1: Stainless Steels) and is manufactured from medical-grade 420 stainless steel with optimized hardness (52–56 HRC), corrosion resistance, and repeated autoclave compatibility (up to 134 °C, 21 psi, 18 min per cycle). The set supports consistent tissue handling across longitudinal studies by minimizing mechanical trauma through ultra-fine tip geometries, calibrated jaw alignment, and controlled spring tension—critical parameters for maintaining viability in immunocompetent, transgenic, or aged mouse models.

Key Features

• Precision-ground tips with sub-100 µm edge tolerances: Straight and 45°-angled fine forceps (F11020-11 / F11021-11) feature 0.05 × 0.01 mm and 0.10 × 0.06 mm tip profiles for neural tract isolation and vessel manipulation.
• Dual-configuration Vannas spring scissors (S11001-08 / S11002-08): 8.5 cm length with triangular cross-section blades and dual-point sharpness for clean, low-shear cutting of dura mater and fascial layers.
• Olsen-Hegar needle holders (F31047-12): Integrated blade geometry enables simultaneous suture passage and precise transection—optimized for 5-0 and finer monofilament sutures used in murine anastomosis.
• Colibri self-retaining retractor (R22029-04): Adjustable 1.5 cm spread with non-slip tungsten-carbide coated tips ensures stable exposure during intracranial or abdominal access without tissue compression artifacts.
• IRIS Super Cut scissors (S18001-09 / S18002-09): Cryo-hardened stainless steel blades with mirror-polished edges deliver reproducible cuts in delicate connective tissues and embryonic membranes.
• Full traceability: Each instrument bears laser-etched serial identifiers compliant with UDI (Unique Device Identification) requirements per FDA 21 CFR Part 830 and EU MDR Annex I §10.4.1.

Sample Compatibility & Compliance

The SP0009-M set is validated for use in C57BL/6, BALB/c, CD-1, and NSG mouse strains weighing 18–30 g. All instruments meet ASTM F899-22 (Standard Specification for Stainless Steels for Surgical Instruments) and are certified biocompatible per ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization). Packaging complies with ISO 11607-1:2019 for sterile barrier systems and supports ethylene oxide (EtO), gamma, and steam sterilization protocols. The set aligns with GLP-compliant surgical SOPs and supports audit readiness for AAALAC-accredited facilities.

Software & Data Management

While the SP0009-M is a hardware-only instrument set, its configuration is fully integrated into RWD’s LabLog™ Inventory & Sterilization Tracking System (v3.2+). Users may assign digital asset IDs, log autoclave cycles (temperature, pressure, duration), record instrument usage per animal ID, and generate sterilization certificates compliant with 21 CFR Part 11 electronic signature requirements. Audit trails include timestamped operator credentials, maintenance history, and calibration verification logs for forceps jaw parallelism and scissor blade coaptation.

Applications

• Intracerebral electrode implantation and optogenetic fiber placement
• Carotid artery ligation and femoral vein catheterization
• Orthotopic tumor transplantation (e.g., GL261 glioma, 4T1 mammary carcinoma)
• Retinal injection and intraocular lens implantation
• Embryonic day (E) 12.5–18.5 microdissection for organogenesis studies
• Subcutaneous osmotic pump implantation with minimal fascial disruption

FAQ

Is the SP0009-M set compatible with standard surgical trays and sterilization cassette systems?
Yes—the instruments fit standard 31 × 21 cm stainless steel or polypropylene sterilization trays and are dimensionally aligned with ANSI/AAMI ST79:2023 tray loading guidelines.
Can individual instruments be reordered separately?
All components are available as standalone SKUs via RWD’s global distribution network; part numbers match those listed in the configuration table.
Does RWD provide validation documentation for autoclave cycles?
Yes—each batch includes a Certificate of Conformance with material test reports (MTRs), heat treatment records, and sterilization validation summaries per ISO 17664-1.
Are replacement blades or needles included in the set?
The set includes one box (100 units) of #11 surgical blades (S31011-01); additional blades, suture packs, and needle holder inserts are sold separately.
What is the recommended sharpening interval for the IRIS Super Cut scissors?
Under typical academic lab usage (≤5 procedures/week), sharpening is recommended after 200–250 uses or when measured cutting force exceeds 120 g (per ASTM F1551-22).
