Actuation lockout for a surgical instrument

A surgical instrument comprising:

• a power transmission including a trigger and a fastener driver operatively coupled to the trigger, wherein actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position;
• one or more locking surfaces associated with the fastener driver;
• and
• a control surface that is moved between a locked configuration and an unlocked configuration when the trigger is actuated from the first configuration towards the second configuration, wherein the control surface obstructs motion of at least one of the one or more locking surfaces to prevent movement of the fastener driver between the first position and the second position when the control surface is in the locked configuration.

A method of operating a surgical instrument, the method comprising:

• initially restraining movement of a fastener driver operatively associated with a trigger using an actuation lockout system;
• actuating the trigger from a first configuration towards a second configuration;
• moving the actuation lockout system from a locked configuration to an unlocked configuration in response to said actuating of the trigger;
• and
• moving the fastener driver from a first position to a second position when the actuation lockout system is in the unlocked configuration.
