Abstract
Surgical instrument calibration methods, systems, and devices are provided that allow a virtual representation of a surgical instrument to be modified to adjust for any variations in a distal tip of a surgical instrument. For example, an instrument calibration system is provided that can have a surgical instrument, a calibration instrument, and a monitoring system. The surgical instrument can have a distal tip and an orientation element thereon, and the calibration instrument can have a pivot point thereon and a calibration reference element attached thereto. The monitoring system can be configured to record movement of the surgical instrument with respect to the calibration instrument when the tip of the surgical instrument is inserted into the pivot point of the calibration instrument, and to calculate a deviation of the tip of the surgical instrument from a predefined ideal tip based on the recorded movement.
