Abstract
A surgical instrument includes a surgical end effector having at least one actuation assembly to effect a surgical procedure when actuated, an electric motor operationally connected to the end effector to operate the at least one actuation assembly, and a power supply electrically connected to the motor and selectively powering the motor to actuate the actuation assembly. The power supply has a battery cell with a critical current rate and, when activated to power the motor and actuate the actuation assembly, operates the cell at a super-critical current rate or at an average current rate above the critical current rate. The power supply selectively powers the motor to actuate the assembly less than 16 times during a clinical life of at least one of the end effector, the motor, and the power supply. When actuated, the assembly operates only between 0.5 seconds and 16 seconds in duration.
