摘要：
A system comprising a surgical instrument is disclosed. The surgical instrument includes a handle, a shaft, a plurality of magnets, a plurality of sensors configured to determine a distance away from one or more of the plurality of magnets, and a processor communicatively coupled to the plurality of sensors. The processor is configured to determine a three dimensional change in position of the shaft by computing a three dimensional change in position of the one or more magnets, using the change in the distances determined by the one or more plurality of sensors.
