Arthrex AR-3032-4.5 4.5mm Cutter Cannula w/ AR-3033-4.5 Blunt Obturator, Adapter

Arthrex 4.5mm Arthroscopy Cannula 3-Piece Set (AR-3032-4.5 / AR-3033-4.5 / AR-3035)

The Arthrex AR-3032-4.5 Set is a premium, reusable instrumentation kit engineered for portal maintenance and fluid management during arthroscopic procedures. The core 4.5 mm Cutter Cannula provides a stable, high-flow working channel for 4.0 mm scopes and shavers, featuring a specialized J-lock hub for secure attachment. This set is specifically designed for surgeons who prefer the tactile feedback and durability of stainless steel over disposable alternatives, ensuring consistent joint distension and reduced fluid extravasation into surrounding soft tissues.

The set includes the AR-3033-4.5 Blunt Pencil-Tip Obturator, which is perfectly indexed to the cannula length for atraumatic portal entry, protecting the articular cartilage and synovial lining. The AR-3035 Inflow Adapter bridges the gap between the cannula and standard surgical tubing, providing a 360° swiveling connection that prevents line tangling during lateral or medial camera rotations.

Clinical & Operational Advantages

• Optimized Fluid Dynamics: The 4.5 mm diameter is optimized for high-volume inflow/outflow, maintaining a clear visual field even during aggressive mechanical debridement.

• Portal Integrity: The metal construction ensures the portal remains patent even in patients with high BMI or thick subcutaneous tissue, where plastic cannulas often kink.

• Safe Joint Entry: The AR-3033-4.5 blunt obturator is designed to "part" rather than "cut" tissue, significantly reducing the risk of iatrogenic chondral injury upon insertion.

• Cost-Effective Reusability: Unlike single-use disposables, this validated stainless steel set provides a lower cost-per-case while maintaining the high-performance standards of the Arthrex ecosystem.

Condition

• Status: Used – Usable Condition (USED-SI).

• Functional Assessment: The J-lock mechanism is secure and non-binding. The AR-3033-4.5 obturator is straight and seats perfectly within the cannula. The AR-3035 adapter swivels freely and the lumen is clear.

• Cosmetic Status: Shows visible signs of normal clinical use, including surface scuffs, minor scratches, and typical sterilization-related patina on the metal surfaces. These are cosmetic and do not impact the fluid-tight seal or surgical performance.

• Sterilization Note: This set is provided non-sterile. It must be professionally cleaned (ensuring the internal lumen is brushed) and autoclaved per your facility's validated Arthroscopy protocols prior to use.
