Abstract
A staple cartridge comprising a power management circuit is disclosed.
Claims18
A surgical stapling system, comprising:
- a stapling instrument, comprising:
- a shaft;
- a power supply circuit extending through said shaft, wherein said power supply circuit comprises a power supply antenna;
- and
- a jaw;
- and
- a staple cartridge seatable in said jaw, wherein said staple cartridge comprises:
- a cartridge body;
- staples removably stored in said cartridge body;
- a power management circuit comprising a charge accumulator and a power transfer antenna, wherein said power transfer antenna is aligned with said power supply antenna to receive power from said stapling instrument when said staple cartridge is seated in said jaw, and wherein said power supply circuit is capable of supplying a maximum current to said power management circuit;
- and
- a sensor circuit in communication with said power management circuit which is capable of drawing a sensor supply current from said power management circuit, wherein said sensor supply current is larger than said maximum current.

A surgical stapling system, comprising:
- a stapling instrument, comprising:
- a shaft;
- a first antenna circuit;
- a second antenna circuit;
- and
- a jaw;
- and
- a staple cartridge seated in said jaw, wherein said staple cartridge comprises:
- a cartridge body;
- staples removably stored in said cartridge body;
- a power management circuit comprising a first antenna coil and a second antenna coil, wherein said first antenna circuit is aligned with said first antenna coil and said second antenna circuit is aligned with said second antenna coil when said staple cartridge is seated in said jaw, wherein said power management circuit comprises a processor in communication with said first antenna coil and said second antenna coil, wherein said processor is operable in a low power mode and a high power mode, wherein said processor switches from said low power mode to said high power mode after said processor receives a first wake input from said first antenna circuit and a second wake input from said second antenna circuit.
