摘要：
A method of implanting a bone anchor in a vertebra comprises engaging a tip of a flexible drill bit with boney structure of the vertebra, rotating the flexible drill bit at a slow speed, pushing the drill bit into exterior cortical bone of the boney structure of the vertebra, guiding the flexible drill bit into cancellous bone of the vertebra, receiving a tactile output generated by the flexible drill bit indicating resistance of interior cortical bone of the boney structure against the flexible drill bit, and reorienting a trajectory of the flexible drill bit toward the cancellous bone of the vertebra in reaction to the tactile output.
