<P>PROBLEM TO BE SOLVED: To provide a method for operating an electric surgical stapling device for stapling when optimal tissue compression (OTC) exists, to provide a cryptographic identification for a disposable part such as a staple cartridge, and to provide a manual release device allowing recovery from partial actuation or a jam. <P>SOLUTION: A surgical instrument includes a surgical end effector having a receiving portion for removably receiving an interchangeable part 2200. The receiving portion has a communication connection. A handle connected to the end effector actuates the end effector. The handle has a controller electrically connected to the communication connection for authenticating the interchangeable part when placed at the end effector. The interchangeable part is removably connected to the receiving portion and has an encryption device electrically removably connected to the communication connection when placed at the receiving portion. The encryption device authenticates the interchangeable part when queried by the electric controller. <P>COPYRIGHT: (C)2013,JPO&INPIT |
