Abstract
The present teaching relates to surgical position marking. A 3D model for an organ includes cut points forming a surgical trajectory. Each cut point has a 3D coordinate and a surface norm in the model space. When projected into a workspace, a mapped cut point is created with a mapped 3D coordinate and a mapped surface norm in the workspace. With a surgical instrument with a tip and a force sensor attached thereto, some mapped cut points are marked along a direction determined based on a reaction force sensed by the force sensor when the tip touches the cut point.
