Arthroscopic Ablator

Arthroscopic ablator is a device specifically designed for use in arthroscopic ablative processes. As a category of radiofrequency ablation devices, the arthroscopic ablator is widely used in minimally invasive joint surgeries—such as knee, shoulder, and hip arthroscopy—primarily for the removal and reshaping of soft tissue or for hemostasis.

Main functions and features

Tissue resection and trimming: Commonly used for meniscus trimming, synovectomy, or cleaning of cruciate ligament stumps, this device reduces micro-cracks on the tissue surface through "tissue smoothing" when compared to traditional mechanical shavers.

Low-temperature plasma technology (Coblation): Many modern ablation devices, including those from leading manufacturers, employ bipolar plasma technology. This allows the arthroscopic ablator to generate a plasma layer at the electrode tip, ablating tissue by breaking molecular bonds rather than through high-temperature thermal effects. It typically operates at 40–70°C, minimizing damage to surrounding healthy cartilage.

Real-time monitoring and control: High-end versions of the arthroscopic ablator feature feedback control functions that monitor local temperature and impedance in real time, adjusting power or pump flow rates to ensure safety and accuracy throughout the procedure.

Diverse probes: To adapt to narrow joint spaces, probes are available in various angles such as 30°, 50°, or 90°. Many probes also integrate suction to remove debris and air bubbles during ablation.

Clinical application examples

Knee joint: Partial meniscectomy, chondroplasty, and debridement of residual tissue before ACL reconstruction.

Shoulder joint: Acromioplasty, tissue preparation for rotator cuff repair, and bursectomy.

Small joints: Treatment of synovial tissue in the wrist, ankle, and elbow joints.

With its precision, versatility, and advanced safety features, the arthroscopic ablator has become an essential tool in modern arthroscopic surgery.
