Abstract

A surgical cutting and fastening 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 system, comprising:

a cordless surgical cutting and fastening instrument, comprising;

an end effector;

a shaft connected to the end effector, the shaft comprising a drive train for driving the end effector;

an electric motor connected to the shaft; and

a device memory assembly that is detachable and removable from the instrument, wherein the device memory assembly comprises a device memory unit for storing one or more operating parameters of the instrument, where the one or more operating parameters comprise a value for the number of firings by the end effector of the instrument; and

a base unit that is separate from the instrument, wherein the base unit comprises a base unit memory for storing the value for the number of firings that is downloaded from the device memory unit.

2. The system of claim 1, wherein the base unit is for downloading the one or more operating parameters when the device memory assembly is detached and removed from the instrument.

3. The system of claim 1, wherein the device memory assembly comprises a device processor connected to the device memory unit.

4. The system of claim 3, wherein the removable device memory assembly further comprises a RFID transponder for reading a RFID value of at least one replaceable component of the instrument, and wherein the device memory unit is in communication with the RFID transponder for storing the RFID value of the at least one replaceable component of the instrument read by the RFID transponder.

5. The system of claim 4, wherein the device processor is programmed to determine whether the at least one replaceable component is proper for use in the instrument based on the RFID value of the at least one replaceable component of the instrument read by the RFID transponder.

6. The system of claim 5, wherein the device processor is further programmed to disable operation of the instrument upon a determination that the at least one replacement component is not proper for use in the instrument.

7. The system of claim 4, wherein the base unit memory is further configured for storing the RFID value of the at least one replaceable component of the instrument upon downloading from the device memory unit.

8. The system of claim 1, wherein:

the electric motor is for rotating the shaft; and

the device memory assembly comprises a power source that is connected to, and powers electrically, the electric motor when the device memory assembly is inserted in the instrument.

9. The system of claim 8, wherein the power source comprises a chargeable DC power source.

10. The system of claim 9, wherein the device memory assembly further comprises means for measuring a charge level across the chargeable DC power source.

11. The system of claim 8, wherein:

the surgical cutting and fastening instrument comprises a handle; and

a processor in communication with the first data storage means, wherein;

the first data storage means is for storing the RFID value; and

the processor is for determining whether the at least one replaceable component is proper for use in the instrument based on the RFID value of the at least one replaceable component of the instrument read by the RFID transponder.

18. The system of claim 16, wherein:

the end effector is articulable;

an articulation angle of the end effector.

19. A system, comprising:

a cordless surgical fastening instrument, comprising;

an end effector comprising a replaceable fastener cartridge assembly including a cartridge body and fasteners removably stored in the cartridge body;

a shaft, wherein the end effector extends from the shaft;

a firing drive system configured to perform a fastener firing stroke to eject the fasteners from the cartridge body; and

a memory device configured to store one or more operating parameters of the surgical fastening instrument, where the one or more operating parameters comprise a value for the number of fastener firing strokes experienced by the end effector of the instrument; and

a computer system that is separate from the surgical fastening instrument, wherein the computer system is configured to download data from the surgical fastening instrument including the one or more parameters and the value for the number of firing strokes so that the manufacturer of the surgical fastening instrument can evaluate and analyze the data.
