1. A surgical device comprising:
a power source;
a motor coupled to the power source;
a controller configured to control the motor;
a reload including a plurality of staples; and
an anvil assembly movable relative to the reload by the motor,
wherein the controller is configured to control the motor to:
move the anvil assembly from a distal clamp position to a proximal clamp position;
maintain the anvil assembly at the proximal clamp position for a preset period of time; and
reverse the anvil assembly to move the anvil assembly distally from the proximal clamp position to achieve tissue hysteresis.
