Abstract

In various embodiments, a surgical instrument is disclosed. The surgical instrument comprises a handle assembly having a closure trigger, a closure actuator coupled to the closure trigger at a first pivot, and a closure spring. The closure actuator moves proximally on a longitudinal axis in response to actuation of the closure trigger. The closure spring applies a force vector to the closure spring tangential to the longitudinal axis. A shaft assembly is coupled to the handle assembly. An end effector is coupled to a distal end of the shaft assembly. The end effector comprises a jaw assembly comprising a first jaw member and a second jaw member. The first jaw member is pivotally moveable with respect to the second jaw member. At least one of the first and second jaw members are operatively coupled to the closure actuator.
