Estimating the term…
A surgical instrument has a staple cartridge housing a plurality of staples and an anvil configured to capture tissue therebetween. The surgical instrument also has a firing assembly configured to deploy the plurality of staples into the captured tissue during a firing sequence, and a handle that includes an electric motor operably coupled to the firing assembly, wherein the electric motor is configured to motivate the firing assembly to deploy the plurality of staples into the captured tissue during the firing sequence, and a power pack. The power pack includes rechargeable battery cells configured to power the electric motor, at least one battery-cell health indicator, and an electronic control circuit configured to assess whether a subset of rechargeable battery cells is damaged during the firing sequence based on at least one measurement performed by the at least one battery-cell health indicator.
A power pack for use with a surgical instrument, the surgical instrument comprising a control circuit and an end effector configured to cut captured tissue during a firing sequence of the surgical instrument, the power pack comprising:
A surgical instrument, comprising:
A method of improving the performance of a power pack during a firing sequence of a surgical instrument, wherein the power pack comprises a plurality of battery cells configured to power the surgical instrument and a sensor configured to detect parameters associated with the plurality of battery cells, wherein the surgical instrument comprises a control circuit, a voltage converter, and an end effector configured to capture and cut tissue, the method comprising:
