METHOD FOR BONE RESECTION Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: guiding spokes are directed through the bone strictly along the border of the pathological focus in the preoperative period. A series of computer tomograms is performed, an individual stereolithographic template with a through slot with jumpers corresponding to the line of bone resection is designed and printed on a 3D printer. The guide spokes are intraoperatively combined with their template slots. A tool is screwed into the template, having a sharp spike at one end for fixation in the bone, and a T-shaped handle at the other to hold the template. The template is pressed against the bone and an oscillating saw or cutter is used to resect the bone segment along the through slot of the template, gradually destroying its jumpers. The resected bone segment is removed, pulling the T-shaped tool handle. Without removing the template, the necessary treatment of the bone cavity is performed. The template and guide spokes are dismounted.

EFFECT: method allows to increase the accuracy of resection, taking into account individual topographic and anatomical features.
