Abstract

A system for verifying a tool for use in a surgical procedure includes a mechanical interface configured to be affixed to a portion of a patient's anatomy, wherein the mechanical interface comprises at least a first portion having a first diameter and a second portion having a second diameter. The system further includes a probe configured to be inserted into the mechanical interface to establish a checkpoint location, and a computing system configured to determine a location of a portion of the probe when the probe is inserted a maximum distance into the mechanical interface, wherein the location of the portion of the probe establishes the checkpoint location. The computing system is further configured to verify a surgical tool by comparing the checkpoint location to a location of a portion of the surgical tool when the surgical tool is inserted a maximum distance into the mechanical interface.
