METHOD OF PUNCTURE TRANSCUTANEOUS MICRODISCECTOMY AT L5-S1 LEVEL BY MEANS OF MECHANIC DECOMPRESSOR Russian patent published in 2012 - IPC A61B17/34 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to neurosurgery and can be applied in treatment of degenerative-dystrophic diseases of spine, complicated by hernia-formation at L5-S1 level. Essence of method lies in puncture transcutaneous microdiscectomy at L5-S1 level by means of mechanical decompressor with curved guide-needle. Guide-needle is preliminarily curved in point which is at 3 cm distance from distal needle end at angle 35-40°. It is introduced transcutaneously at angle 35-50° to body surface in frontal plane, with lateral inclination and 8-12 cm indent from the line of spinous processes. In the course of needle movement its trajectory is manipulated. Posterior upper axis of ilium is passed round. After that, intervertebral disc is approached parallel to closing plates and punctured in the centre of nucleus pulposus. Application of claimed invention makes it possible to improve, simplify and accelerate puncture access into intervertebral disc L5-S1, thus reduce operation time, more accurately puncture intervertebral disc parallel to closing plates, remove larger amount of nucleus pulposus.

EFFECT: removal of large amount of nucleus pulposus ensures reduction of intervertebral disc volume, reduction of intradisc pressure and elimination of discoradicular and (or) discomedullary conflict.
