A robot-guided system to assist orthopaedic surgeons in performing
orthopaedic surgical procedures on pre-positioned inserts, including for
the fixation of bone fractures, and especially for use in long bone
distal intramedullary locking procedures. The system provides a
mechanical guide for drilling the holes for distal screws in
intramedullary nailing surgery. The drill guide is automatically
positioned by the robot relative to the distal locking nail holes, using
data derived from only a small number of X-ray fluoroscopic images. The
system allows the performance of the locking procedure without trial and
error, thus enabling the procedure to be successfully performed by less
experienced surgeons, reduces exposure of patient and operating room
personnel to radiation, shortens the intra-operative time, and thus
reduces post-operative complications.
