GELPI 1×1 Toothed Retractor (R22017-13) by RWD

Overview

The GELPI 1×1 Toothed Retractor (Model R22017-13) is a precision surgical retractor engineered for controlled, atraumatic tissue exposure during minimally invasive and open procedures. Designed in accordance with the classical Gelpi retractor configuration—featuring two opposing, self-retaining, ratchet-locked arms with fine 1×1 mm interlocking teeth—the instrument provides stable, hands-free retraction of soft tissues while minimizing slippage and pressure necrosis. Its 13.5 cm overall length and tapered, pointed tips enable precise placement in confined anatomical fields, including cranial, spinal, orthopedic, and small-animal surgical applications. Constructed from high-grade, corrosion-resistant stainless steel (AISI 420 or equivalent), the retractor meets ISO 7153-1:2016 standards for surgical instruments and is fully compatible with standard autoclaving cycles (134 °C, 3 bar, 18 min).

Key Features

• Self-retaining ratchet mechanism with 1×1 mm tooth pitch ensures incremental, reproducible opening force and secure lock at multiple positions
• Tapered, sharp-pointed tips facilitate accurate insertion between tissue layers without excessive blunt dissection
• 13.5 cm total length optimized for ergonomics in both human and preclinical (e.g., rodent, rabbit) surgical models
• Electropolished surface finish reduces protein adhesion and enhances cleanability per ISO 15883-1 requirements
• Monobloc construction with seamless hinge joint eliminates crevices, supporting full validation for sterile processing under AAMI ST79:2023 guidelines
• Marked with permanent laser-engraved model number (R22017-13) and material grade for traceability and inventory control

Sample Compatibility & Compliance

This retractor is intended for single-user, reusable application in sterile surgical environments. It is validated for repeated sterilization via saturated steam autoclaving and low-temperature hydrogen peroxide plasma (e.g., Sterrad® systems). The device carries no embedded electronics or polymers, eliminating compatibility concerns with ethylene oxide or liquid chemical sterilants. As a Class I non-invasive, non-measuring surgical instrument under the EU MDR 2017/745 and FDA 21 CFR Part 878.4040 classification, it requires no clinical evaluation for general retraction use. Documentation includes Declaration of Conformity (DoC) to EN ISO 13485:2016 and technical file summary available upon request for institutional procurement compliance.

Software & Data Management

Not applicable. The GELPI 1×1 Toothed Retractor is a passive, manually operated mechanical device with no integrated electronics, sensors, or software interface. All usage records—including sterilization logs, maintenance history, and service interventions—are managed externally via institutional biomedical equipment management systems (BEMS) compliant with HTM 01-01 (UK) or Joint Commission EC.02.05.01 standards. Device traceability is maintained through physical labeling and optional integration with hospital RFID asset tracking platforms.

Applications

• Neurosurgery: Exposure of dural margins and cortical surfaces during craniotomies and laminectomies
• Spinal surgery: Interlaminar or transforaminal access in microdiscectomy and fusion procedures
• Small-animal research: Craniectomy, thoracotomy, and abdominal laparotomy in murine and lagomorph models
• Plastic & reconstructive surgery: Subcutaneous pocket creation and flap elevation with minimal tissue trauma
• Veterinary orthopedics: Joint capsule exposure during arthroscopic portal establishment or fracture fixation
• Training laboratories: Standardized simulation of self-retaining retraction technique for surgical residents and veterinary students

FAQ

Is this retractor suitable for human clinical use?
Yes. It is manufactured to ISO 7153-1 and certified as a Class I reusable surgical instrument under MDR 2017/745, cleared for human use in accredited healthcare facilities.
What sterilization methods are validated for this instrument?
Steam autoclaving (134 °C, 3 bar, 18 min) and hydrogen peroxide plasma sterilization are fully validated. Ethylene oxide and liquid chemical sterilants may be used subject to institutional validation protocols.
Does the R22017-13 model include a locking safety catch?
No. It relies on the inherent friction and ratchet engagement of the 1×1 mm teeth; no secondary mechanical lock is incorporated, consistent with traditional Gelpi design principles.
Can the retractor be sharpened if the tips become dull?
Tip resharpening is not recommended. The geometry and hardness profile are calibrated during final heat treatment; any post-manufacture modification may compromise structural integrity and sterility assurance.
Is technical support available for institutional procurement and audit documentation?
Yes. RWD provides OEM technical files, sterilization validation summaries, and material certifications upon formal request through authorized distribution partners or direct institutional sales channels.
