METHOD OF VERTEBRAL FRAGMENT RESECTION Russian patent published in 2010 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to vertebrology. The approach to an involved vertebral segment is ensured by formation of at least three punctures with longitudinal axes of at least two of them directed on the involved segment. A thoracoport is fixed in each puncture. The resection of the involved vertebral fragments is enabled by a drilling machine with its shaft transmitting rotation to a milling head and having a length not less a thorax thickness and provided with a fixed protective casing with its external diametre being less than a drift diametre of the thoracoport. A video camera with a light source is delivered to the operative area through the second puncture directed to the involved segment. Through the third puncture, an instrument used to slide out the internal organs blocking the operative area is introduced. After the removal of bone material, a valley formed in a vertebra is filled with bone cement or ground bone material mixed with bone cement. That is ensured by a syringe with a needle of an external diametre being less than a diametre of the thoracoport, and an internal diametre threefold exceeding the greatest fraction of the bone material. The fractured bone material is removed through the first puncture, after the shaft of the drilling machine is removed. The fractured bone material is removed through the additional fourth puncture. The punctures are formed in the intercostal space. For the vertebral resection, the drilling machine of shaft speed min. 4000 rpm is used.

EFFECT: higher efficiency.
