PERCULINE nucleo is a universal instrument system for percutaneous nucleoplasty of the lumbar spine. It is used for interventional therapeutic pain treatment using 4 MHz radiofrequency. The instrument set is used for percutaneous access to the intervertebral discs, for tissue preparation and dissection with manual instruments, and for coagulation, tissue reduction and ablation using 4 MHz radiofrequency current.
While rongeurs are used to remove the material directly from the disc, the application of radiofrequency current with bipolar TipControl instruments causes a volume reduction of the disc tissue on the one hand and the destruction of the small nerve fibers on the fibrous ring of the disc on the other. The spinal nerves are indirectly decompressed and the destruction of the nerve fibers prevents the transmission of pain information to the brain. The primary therapeutic goal of nucleoplasty is decompression of the nerve structures, by volume reduction of the disc with the help of radiofrequency ablation as well as mechanical removal of tissue with rongeurs.
