Système d'ablation par radiofréquence intra-osseuse pour les tumeurs de la colonne vertébrale

Système d'ablation par radiofréquence intra-osseuse pour les tumeurs de la colonne vertébrale

Un dispositif spécialisé peu invasif conçu pour délivrer une énergie de radiofréquence ciblée, ablant efficacement les tumeurs de la colonne vertébrale tout en préservant les tissus sains environnants et en réduisant le temps de récupération de l'intervention.

Informations

Spinal metastases and other osseous lesions present a challenging clinical scenario—pain, neurological compromise, and potential instability make effective treatment critical. This Intraosseous Radiofrequency Ablation (RFA) system offers a promising, peu invasif technique for ciblée destruction of tumor tissue within the vertebra. Utilizing a 17 G introducer needle, 5 Fr catheter, and a Thermo ablation probe with multi-level safety monitoring, the system delivers contrôlé ablation to destroy neoplastic cells while preserving patient safety.

Caractéristiques principales

User-Friendly Touchscreen Display
  • Intuitive Interface: Operators can effortlessly select and fine-tune ablation parameters (e.g., temperature, power) while actively visualizing real-time feedback.
  • Probe Recognition with RFID: The system automatically identifies the catheter model and sets default parameters accordingly, streamlining setup.
  • Temperature & Power Output Tracking: Continual analysis prevents overheating or under-treatment, eliminating potential carbonization risks.
  • Warning System: Sound and light pulses signal high or low temperature and indicate the procedure’s standby operation time (up to 250 seconds).
  • No Carbonization: Maintains temperature in a defined range (80–110 °C) with max power at 40 W, enabling efficace tissue necrosis while minimizing excessive heat spread.
  • Multi-Stage Approach: For more extensive lesions, multiple sequential ablations can be planned, safeguarding adjacent structures and nerves.
  • 17 G Introducer Needle + 5 Fr Introducer Catheter: Facilitates stable placement into the vertebral body under fluoroscopic ou radioscopic imaging guidance.
  • Thermo Probe avec Heating Element (1–2.5 mm diameter, 2–4 cm length): Allows the ablation zone to be tailored to the lesion size, ensuring thorough coverage and minimal healthy bone disruption.

Avantages et applications cliniques

Spinal Metastases Management
  • Pain Relief: Targeted ablation of tumor tissue can reduce pain and restore some stability to compromised vertebrae.
  • Peu invasif: Often performed under sedation or local anesthesia, diminishing hospital stays and accelerating patient mobilization.
  • Lower Risk of Overheating: With regulated temperature control, surrounding bone and spinal cord are less prone to thermal injury.
  • Enhanced Synergy: Post-ablation, vertebral augmentation (e.g., cementoplasty) can further stabilize the spine if needed.
  • Radioscopic/Fluoroscopic Guidance: Ensures precise probe positioning and continuous observation of the ablation process, improving operator confidence and patient safety.
  • Controlled Approach: Suitable for metastatic disease in the vertebral body, pedicle, or accessory spinal regions.
  • No External Introducer: Single 17 G access route can be withdrawn promptly following ablation—helping reduce procedural complexity and infection risk.
  • Immediate Assessment: Intra- or post-procedure imaging can quickly confirm ablation zone coverage, providing data for possible second-round ablation if needed.
