Abstract
A surgical instrument includes a handle assembly and an end effector. The handle assembly includes a trigger, a push plate coupled to the trigger, wherein actuation of the trigger rotates the push plate, a clamp plate operably coupled to the push plate, wherein actuation of the trigger to a first rotation rotates the clamp plate, and a firing plate operably coupled to the push plate, wherein actuation of the trigger between the first rotation and a second rotation rotates the firing plate. The end effector includes a jaw assembly which includes a first jaw member and a second jaw member, wherein rotation of the clamp plate transitions the jaw assembly between an open configuration and an approximated configuration by moving at least one of the first jaw member and the second jaw member relative to the other one of the first jaw member and the second jaw member.
