Description
Le XISHAN RF Electrosurgical Unit (RF-CHA-S1) is a high-frequency radiofrequency surgical platform engineered specifically for full-endoscopic spine surgery (PELD / PETD / PEID / UBE), neurosurgery, and delicate minimally invasive tissue management. Operating at 4.0 MHz (Monopolar) and 1.7 MHz (Bipolar) megahertz frequencies, it delivers micro-controlled cellular vaporization and instant low-voltage hemostasis with minimal lateral thermal diffusion.
Featuring 5 selectable operative energy modes and intelligent probe recognition, the RF-CHA-S1 empowers spine surgeons to perform safe annulus fibrosus modulation (annuloplasty), nucleus pulposus ablation (nucleoplasty), ligamentum flavum shrinkage, and epidural venous plexus hemostasis directly adjacent to the dural sac and exiting nerve roots.
Radiofrequency Engineering & Safety Innovations
Dual Megahertz RF Architecture
4.0 MHz monopolar frequency allows smooth low-temperature tissue incision; 1.7 MHz bipolar frequency provides localized, non-sparking vascular coagulation without tissue sticking.
5 Clinical Output Modes
Dedicated modes for Monopolar Cut (100W), Blend (70W), Coag (50W), and Bipolar Low/High Coag (40W/100W) cover both delicate micro-dissection and rapid bulk hemostasis.
Smart Memory & Tool Detection
Intelligently identifies connected spinal probes and automatically restores the surgeon’s latest preferred energy settings upon startup, streamlining OR turnaround.
7-Inch Color Touch Interface
Large intuitive touch screen with high-contrast numerical displays, continuous impedance monitoring, and real-time visual output power indicators.
Spinal Instrument & Electrode Compatibility
- Spinal Endoscope Channel Access: Seamlessly accommodates 1.8mm and 2.5mm radiofrequency electrodes through standard 2.8mm–4.3mm operative spinal endoscope channels (e.g., XISHAN EDS-ART-SPINE).
- Articulating & Steerable Probes: Supports bendable and straight electrodes (260mm / 360mm) for navigating around the ventral dural margin and intervertebral foramina.
- Sub-Millimeter Thermal Margin: Ultra-fine low-temperature sparkless coagulation prevents thermal radiculopathy and protects the spinal cord.
Indications cliniques et étendue chirurgicale
- Full-Endoscopic Spine Surgery: Percutaneous Endoscopic Transforaminal Discectomy (PETD), Interlaminar Discectomy (PEID), and Unilateral Biportal Endoscopy (UBE).
- Disc Modulation & Annuloplasty: Annulus fibrosus remodeling, herniated fragment ablation, and sensory nerve ending desensitization.
- Epidural & Foraminal Hemostasis: Rapid coagulation of epidural venous plexus bleeding and hypervascularized foraminal tissues.
- Neurosurgery & ENT Micro-Procedures: Skull base tumor bed hemostasis and precision soft tissue dissection.
