A surgical instrument including a trigger which can be configured to close a jaw member upon a first actuation of the trigger and advance a staple driver and/or cutting member upon a subsequent, or second, actuation of the trigger. Such a surgical instrument can allow a surgeon to position the surgical instrument in a surgical site and close the jaw member with an initial actuation of the trigger without deploying any staples into, or incising, the tissue. As a result, the surgeon can manipulate the position of the surgical instrument and then actuate the trigger a second time to deploy staples into, and/or incise, the tissue. In at least one such embodiment, the first actuation of the trigger which closes the jaw member can also unlock a firing drive configured to advance the staple driver and cutting member during the second actuation of the trigger. |
