Abstract
A system (200) and method (600) for identifying cutting tools for use during a surgical procedure are described. For example, the system includes a cutting tool assembly (210) including a shaft (212) having a cutting element (214) and at least one identifying feature (216) that uniquely corresponds to the cutting element. The system further includes a drive assembly (220) including a reference pin (224), a motor (230) mechanically connected to the drive assembly, a control unit (240) configured to activate the motor to move the cutting tool assembly such that the reference pin engages with the at least one identifying feature, a sensor system (226) configured to determine positioning information related to the reference pin when the reference pin engages the at least one identifying feature, and a computing unit (250) configured to receive the positioning information from the sensor system and identify the cutting element based upon the position information.
