Recognition of interchangeable component of a device

摘要

RECOGNITION OF INTERCHANGEABLE COMPONENT OF A DEVICE A device and a method are provided for determining a characteristic of an interchangeable component (254) of a surgical instrument. An electrically conductive 5 material having a measurable strength measurable by a hall effect sensor (35) is coupled to the component (254). In another embodiment, a plurality of conductive materials are arranged to form a binary code representing a corresponding of the interchangeable component (254). The number and/or strength of the magnets (30) measurable by the sensors (35) may be dynamically altered such that the status of the surgical instrument is io determinable. 2 28 b 5 S28a 65 18c 18.
