Abstract

Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for preventing skiving of a drilling instrument during a robotic or robot-assisted surgery are disclosed. In one embodiment, a scan of a patient's anatomy can be performed to produce a model of the bone to be drilled into and analysis of the surface can determine if the curvature is such that, if a target trajectory for a bore were followed, skiving of the drilling instrument is likely. If so, an alternate anti-skiving trajectory can be determined. The anti-skiving trajectory of a bore differs from the target trajectory by at least one of entry point, diameter, axis, or depth.
