Abstract

A surgical instrument is disclosed. The surgical instrument includes a control unit and a staple cartridge including a transponder. The control unit is configured to transmit a first wireless signal to the transponder and to receive a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal.

Claims

1. A method of preventing reuse of a staple cartridge in a surgical instrument, the method comprising:

transmitting a first wireless signal to a transponder disposed within the staple cartridge;

receiving a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal;

enabling actuation of a cutting instrument of the surgical instrument when the first electronic state is determined; and

transitioning the transponder from the first electronic state to the second electronic state substantially simultaneously with an actuation of the cutting instrument.

2. The method of claim 1, comprising preventing actuation of the cutting instrument when the second electronic state is determined.

3. The method of claim 1, comprising transmitting a third wireless signal to the transponder to electronically alter at least one component of the transponder.

4. The method of claim 1, comprising electronically altering at least one component of the transponder responsive to a movement of the cutting instrument when actuated.

5. A method of configuring a surgical instrument to prevent reuse of a staple cartridge in the surgical instrument, the surgical instrument comprising a control unit to wirelessly communicate with a transponder contained in the staple cartridge, the control unit comprising a processor and a memory, the method comprising:

programming the processor to cause the control unit to;

transmit a first wireless signal to the transponder and determine an electronic state of the transponder based on receipt or non-receipt of a second wireless signal from the transponder by the control unit in response to the transmission of the first wireless signal, wherein a first electronic state of the transponder corresponds to an unfired state of the staple cartridge, and wherein a second electronic state of the transponder corresponds to a fired state of the staple cartridge; and

enable actuation of a cutting instrument of the surgical instrument when the first electronic state is determined and prevent actuation of the cutting instrument when the second electronic state is determined.

6. The method of claim 5, comprising programming the processor to cause the control unit to:

transmit a third wireless signal to the transponder when the cutting instrument is actuated to effect a transition of the transponder from the first electronic state to the second electronic state.

7. The method of claim 5, comprising programming the processor to determine the first electronic state or the second electronic state based on receipt of the second wireless signal by the control unit.

8. The method of claim 5, comprising programming the processor to determine the first electronic state based on receipt of the second wireless signal by the control unit and determine the second electronic state based on nonreceipt of the second wireless signal by the control unit.
