The surgical instrument includes an energy storage mechanism for storing and providing energy to move the driver and thereby actuate the surgical instrument. Various actuation mechanisms are disclosed which are operable on the energy storage mechanism to control the rate of release of the energy stored in the energy storage mechanism.
