RECOGNITION OF INTERCHANGEABLE COMPONENT OF A DEVICE

摘要

A device and a method are provided for determining a characteristic of an interchangeable component of a surgical instrument. An electrically conductive material having a measurable strength measurable by a hail effect sensor is coupled to the component. In another embodiment, a plurality of conductive materials are arranged to form a binary code representing a corresponding of the interchangeable component. The number and/or strength of the magnets measurable by the sensors may be dynamically altered such that the status of the surgical instrument is determinable.
