Abstract

A surgical cutting and fastening instrument. The instrument comprises an end effector that has a shaft coupled thereto that is coupled to a robotic system. A tool mounting portion includes an electric, DC motor connected to a drive train in the shaft for powering the drive train. A power pack that comprises at least one charge-accumulating device connected to the DC motor for powering the DC motor is provided.

Claims

1. A surgical instrument comprising:

an end effector for receiving a replaceable component;

a shaft connected to a robotic system and the end effector, the shaft comprising a drive train for powering the end effector;

an electric, DC motor connected to the drive train for powering the drive train;

a removable, detachable power pack that is detachable and removable from the DC motor of the surgical instrument, wherein the power pack comprises;

at least one chargeable DC power source connected to the DC motor for powering the DC motor;

a processor;

a power pack memory connected to the processor, wherein the power pack memory is for storing at least one operating parameter of the instrument, wherein the at least one operating parameter of the instrument comprises a number of firings performed by the instrument; and

a RFID transponder for reading a RFID value of the replaceable component of the end effector, and wherein the power pack memory is in communication with the RFID transponder for storing the RFID value of the replaceable component of the instrument read by the RFID transponder,

wherein the processor is programmed to determine whether the replaceable component is proper for use in the instrument based on the RFID value of the replaceable component of the instrument read by the RFID transponder, and wherein the processor is further programmed to prevent the power pack from powering the instrument upon a determination that the replacement component is not proper for use in the instrument and

a charger base, remote from the instrument, for connecting to the power pack when the power pack is detached and removed from the DC motor, wherein the charger base comprises;

a power source for charging the at least one chargeable DC power source of the power pack; and

a charger base memory for downloading the at least one operating a parameter from the power pack memory when the detachable power pack is connected to the charger base.

2. The instrument of claim 1, wherein the power source of the charger base comprises an AC-to-DC power supply.

3. The instrument of claim 1, wherein the power source of the charger base comprises at least one battery.

4. The instrument of claim 1, wherein the at least one chargeable DC power source of the power pack comprises at least one rechargeable battery.

5. The surgical instrument of claim 4, wherein the at least one battery is replaceable.

6. The surgical instrument of claim 5, wherein the at least one rechargeable battery is removable from the power pack.

7. The instrument of claim 1, wherein the at least one chargeable DC power source of the power pack comprises at least one charge-accumulating device.

8. The instrument of claim 7, wherein the at least one charge-accumulating device comprises at least one supercapacitor.

9. The surgical instrument of claim 7, wherein the at least one charge-accumulating device comprises a plurality of series-connected charge-accumulating devices.

10. The surgical instrument of claim 9, wherein the plurality of series-connected charge-accumulating devices comprises a plurality of series-connected supercapacitors.

11. The surgical instrument of claim 9, wherein the power pack comprises a charge management circuit connected to the plurality of series-connected charge-accumulating devices for determining a charge level of the plurality of series-connected charge-accumulating devices.

12. The surgical instrument of claim 1, wherein the power pack memory further is for storing RFID values for components of the instrument, and wherein the power pack further comprises a RFID transponder for reading the RFID values.
