Electrically self-powered surgical instrument with cryptographic identification of interchangeable part
First Claim
1. A method for operating a surgical instrument, which comprises:
- providing a surgical instrument handle;
electrically connecting a controller disposed within the surgical instrument handle to a communication connection of a receiving portion of the surgical instrument;
removably securing an interchangeable part at the receiving portion, the interchangeable part having an encryption device electrically connected to the communication connection when the interchangeable part is at the receiving portion;
authenticating the interchangeable part upon an exchange between the controller and the encryption device;
after at least a partial use of the interchangeable part, storing within the encryption device a used status of the interchangeable part; and
preventing subsequent use of the interchangeable part dependent upon the used status.
