Abstract
A method for encrypted authentication of interchangeable parts of a surgical instrument includes providing a surgical end effector at a distal end of a handle of the surgical instrument and electrically connecting an authentication controller within the handle to a receiving portion of the end effector. An interchangeable part is removably placed at the receiving portion. The interchangeable part is authenticated with the authentication controller when the interchangeable part is seated in the end effector.
