  "abstract": "A surgical instrument includes a handle having a handle frame, a microcontroller having at least one program and memory, and a handle interface supported by the handle frame and in electrical communication with the microcontroller. The instrument further includes a loading unit having a body configured for operative coupling to the handle frame of the handle, and an end effector coupled to a distal end of the body and configured to perform a surgical task. A bracket is mounted to the loading unit and includes a microchip having at least one of authentication data and identification data relating to the loading unit.",
  "claims": [
    "1. A surgical instrument, comprising: a handle including: a handle frame; a microcontroller having at least one program and memory; and a handle interface supported by the handle frame and in electrical communication with the microcontroller; and a loading unit including: a body configured for operative coupling to the handle frame of the handle, and defining a longitudinal axis and having proximal and distal ends; and an end effector coupled to the distal end of the body, the end effector configured to perform a surgical task; and a bracket mounted to the loading unit, the bracket including a microchip at least partially embedded within the bracket, and having at least one of authentication data and identification data relating to the loading unit, the bracket including a bracket interface in communication with the microchip, the bracket interface configured for electrical coupling with the handle interface of the handle.",
    "2. The surgical instrument of claim 1 wherein the microchip of the bracket includes data selected from the group consisting of cartridge size, staple arrangement, staple length, clamp-up distance, date of manufacture, expiration date, compatibility characteristics, unique identifier, and number of uses.",
    "3. The surgical instrument of claim 1 wherein the bracket is mounted to a linear surgical stapling loading unit.",
    "4. The surgical instrument of claim 1 wherein the bracket is mounted to a circular stapling loading unit.",
    "5. The surgical instrument of claim 1 wherein the bracket is releasably mounted to the loading unit.",
    "6. The surgical instrument of claim 1 wherein the handle includes first and second handle interfaces in communication with the microcontroller, the first handle interface configured for electrical coupling with a bracket interface of a first bracket of a first loading unit and the second handle interface configured for electrical coupling to a bracket interface of a second bracket of a second loading unit.",
    "7. The surgical instrument of claim 6 wherein each of the first and second brackets includes a microchip.",
    "8. The surgical instrument of claim 7 wherein the first loading unit is a single use loading unit (SULU) and the second loading unit is a multiuse loading unit (MULU)."
