Takes the pressure

Richard Wolf, working together with pioneering spine surgeons, was the first company to develop a standardized approach to full-endoscopic decompression of lumbar spinal canal stenosis.  The Central Stenosis instrument set represents a true milestone of innovation and advancement in spine endoscopy.

A larger telescope with a correspondingly larger intra-endoscope working channel and larger, stronger instruments were necessary for the more extensive bone and ligament resection necessitated in this operation. The VERTEBRIS stenosis Instrument Set is complemented by the universal motor system and a variety of rigid and articulated burrs.

Interlaminar technique

In interlaminar surgery, the access to the spinal canal is done via the posterior interlaminar window. The dilator is guided directly to the flavum ligament with a dilator without prior puncture. After placing the working sleeve over the dilator, the operation is performed through the high-resolution HD diskoscope under continuous irrigation. The functionality of the components of the access system and the instruments are precisely coordinated. It even allows to pass through the ligamentum flavum and the nerve root with minimal traumatization.  

With special manual instruments and a variety of high-speed burrs available, bone parts of spinal stenoses can be resected under a full-endoscopic view.

VERTEBRIS stenosis

  • High resolution HD endoscopes with shorter working length and increased irrigation rate for full-endoscopic interlaminar approach stenosis surgery.
  • Endoscope adapter to control the distance between endoscope and working sleeve for more ergonomic operation.
  • Optimized ratio of large working channel (5.6 mm) to outside diameter (10.5 mm) for least invasive access trauma and highly effective operation.
  • Fluid management optimized by engineered dimensioning of inflow and outflow preventing neural compression by high pressures of the irrigation fluid.
  • Working Sleeves with atraumatic distal design to protect neural structures.
  • Stable grasping forceps and punches with overload protection and shorter working length for interlaminar approach.
  • Large diameter (5.5 mm) bone punches and Kerrison punches for rapid and precise manual bone removal.
  • Endoscopic high-speed drill system with a variety of large diameter reusable and disposable burrs for mechanical bone resection of laminae and facet.
  • TipControl instruments for 4 MHz radiofrequency coagulation and ablation, and hollow tip RF probes for large scale tissue coagulation and ablation.
