METHOD AND PUNCTURE NEEDLE FOR CARRYING OUT PARACENTETIC NON-ENDOSCOPIC LASER-MEDIATED INTERVERTEBRAL DISK NUCLEOTOMY Russian patent published in 2006 - IPC A61B18/20 

FIELD: medicine.

SUBSTANCE: method involves making access to pulpous nucleus and evaporating a portion of its substance by means of repeated sequential actions with laser radiation having effective wavelength in effective power dose creating cavity in the pulpous nucleus in changing laser beam direction treatment-by-treatment. Adjacent elongated closed canals are formed from the cavity formed in the pulpous nucleus so that their axes were inclined at an acute angle to each other intersecting practically at the same point. The puncture needle is brought to the pulpous nucleus through fibrous disk ring. Some pulpous nucleus substance portion is evaporated and the puncture needle is returned in reversed way so that its distal end is placed into the center of hernial protrusion aside from the fibrous disk ring and direct vaporization of the hernial protrusion is carried out. The puncture needle for carrying out paracentetic non-endoscopic laser-mediated intervertebral disk nucleotomy is manufactured as tubular rod having longitudinal axis, tail and distal part with distal end curved at an acute angle to the longitudinal axis. Distal end bevel is directed towards distal part curvature and has angular plane displacement for making conductor, light guide easily pass and additionally deflecting laser beam from distal light guide end.

EFFECT: enhanced effectiveness of treatment; reduced risk of traumatic complications.
