Description
Der XISHAN Ultrasonic Bone Scalpel System (UT-C-S1) is an advanced ultrasonic surgical platform engineered for high-precision osteotomy, spinal canal decompression, and skull base bone removal. Generating 24,500 to 25,000 longitudinal micro-vibrations per second (24.5–25 kHz) with micro-meter amplitude, it cuts rigid mineralized bone with exceptional efficiency while sparing adjacent elastic soft tissues, dura mater, nerve roots, and major vessels.
Unlike conventional high-speed rotary burs and oscillating saws, the UT-C-S1 produces zero rotational grabbing force and requires no aggressive downward pressure, eliminating soft tissue wrapping, dural laceration, and particulate bone spray.
Selective Cutting & Clinical Safety Advantages
Tissue-Selective Bone Resection
24.5 kHz acoustic resonance breaks rigid bone crystals while elastic soft tissues flex harmonically with the blade, automatically safeguarding the spinal cord, dura, and nerves.
Zero-Torque Longitudinal Oscillation
Linear micro-motion without rotary torque completely prevents catching surgical patties, muscle fibers, or vascular structures, providing unmatched control in deep corridors.
Ultra-Narrow 0.8 mm Bone Kerf
Precision titanium tips produce a kerf width of only 0.8 mm, preserving valuable autologous bone structure and leaving clean, viable osteotomy margins for rapid fusion.
Integrated Direct-Tip Irrigation
Internal fluid channels deliver continuous saline directly to the cutting edge via built-in peristaltic pump, instantly suppressing frictional heat and cavitation misting.
Acoustic Handpiece & Tip Ergonomics
- High-Efficiency Piezoelectric Transducer: Autoclavable titanium alloy handpiece (UHP25K) delivers up to 270 µm tip amplitude across 10 adjustable power levels with minimal grip temperature rise.
- Torque-Limited Fast Mounting: 3-step blade installation with tactile torque threshold and audible click confirmation ensures secure acoustic coupling without overtightening.
- Specialized Tip Portfolio: Curved osteotomy blades, micro-milling rasps (1.8 mm thickness), hook blades, and extended-reach tips for narrow cervical and transforaminal fields.
Clinical Indications & Surgical Applications
- Spine Surgery: Cervical and thoracic laminoplasty, open-door laminectomy, targeted canal decompression, ossification of the posterior longitudinal ligament (OPLL), and transforaminal fusion (TLIF/PLIF).
- Neurosurgery & Skull Base: Craniotomy bone flap elevation, anterior clinoidectomy, optic nerve decompression, and acoustic neuroma acoustic canal unroofing.
- Orthopedic Oncology & Reconstruction: Precision bone tumor en-bloc resection, pelvic osteotomy, and joint revision access.
- Craniomaxillofacial (CMF) Surgery: Le Fort osteotomies, orthognathic reconstruction, and delicate orbital wall osteotomies.
