摘要：
A robotic system for performing minimally invasive spinal stabilization, usingtwo screws inserted in oblique trajectoriesfrom an inferior vertebra pedicle into the adjacent superior vertebra body.The procedure is less traumatic than such proceduresperformed using open back surgery, by virtue of the robot used to guide thesurgeon along a safe trajectory, avoiding damageto nerves surrounding the vertebrae. The robot arm is advantageous since noaccess is provided in a minimally invasive procedurefor direct viewing of the operation site, and the accuracy required foroblique entry can readily be achieved only using roboticcontrol. This robotic system also obviates the need for a large number offluoroscope images to check drill insertion positionrelative to the surrounding nerves. Disc cleaning tools with flexible wireheads are also described. The drilling trajectory is determinedby comparing fluoroscope images to preoperative images showing the plannedpath.
