PROBLEM TO BE SOLVED: To provide a micro-robot integrally or detachably coupled to one end of a catheter for a surgery using the catheter, and a method for positioning an intraoperative photographing image by a reference marker.
SOLUTION: The present invention relates to a micro-robot, especially a micro-robot which is integrally or detachably coupled to one end of a catheter 10 for performing a surgery using the catheter. The micro-robot connected to the catheter can independently perform steering and drilling by using a catheter thinner in thickness than a related art catheter. The a micro-robot is smoothly inserted into a lesion part and removes a risk of injury and infection in an opening operation through precise steering.
