Abstract
A surgical instrument includes an end effector having an actuation assembly to effect a surgical procedure when actuated. An electric motor has a rated operating voltage and is operationally connected to the end effector to operate the actuation assembly. A power supply is electrically connected to the motor and selectively powers the motor to actuate the actuation assembly at least 1 and less than 16 times during a clinical life of at least one of the end effector, the motor, or the power supply. The power supply has a battery cell with a critical current rate. When activated to power the motor and actuate the actuation assembly, the power supply operates the battery cell at a super-critical current rate during a non-zero super-critical pulse discharge period lasting less than approximately 16 seconds. The power supply operates the motor above the rated operating voltage during the super-critical pulse discharge period.
