Abstract
A cutting assembly (200) is configured for use with an electromagnetic tracking system (1). The cutting assembly comprises a bur assembly (10) and a sheath assembly (100). The sheath assembly comprises a sensor (135) configured to measure an electrical field around the cutting assembly, a wire (130) configured to operably connect the sensor and an external computing device (6), and a sensor mount (110) affixed to at least a portion of the sheath assembly, the sensor mount configured to house the sensor and at least a portion of the wire. The sheath assembly is configured to receive at least a portion of the bur assembly such that any impact from magnetic interference caused by, for example, a cutting device (40) within the bur assembly on the sensor is minimized when the cutting device is cutting a patient's bone.
