摘要：
abstract a surgical instrument may include an end effector, an input drive shaft, a closure drive, and / or a firing drive. the end effector may comprise a jaw assembly including a first jaw member and a second jaw member. the end effector may comprise an i-beam member axially translated between a proximal position and a distal position within the end effector. in one embodiment, the input drive shaft may selectively engage the firing drive and / or the closure drive. in one configuration, the closure drive is threadedly engaged with the firing drive allowing the input drive shaft, during a firing stroke, to simultaneously move the closure drive and the firing drive until the closure drive is disengaged from the firing drive. on a reverse stroke, the closure drive may be reengaged with the firing drive. Abstract of the Summary Patent Summary "Swivel Actuable Closure Arrangement for Surgical End Actuator". A surgical instrument is disclosed which may include an end actuator, an input drive rod, a closing actuator and / or a trigger actuator. The end actuator may comprise a jaw assembly including a first jaw member and a second jaw member. the end actuator may comprise an axially translated I-profile member between a proximal position and a distal position within the end actuator. In one embodiment, the input drive rod may selectively engage the trigger actuator and / or the closing actuator. In one configuration, the closing trigger is threaded to the trigger driver, allowing the input trigger rod, during a triggering motion, to simultaneously move the closing trigger and the trigger driver until the closing trigger disengaged from the trigger. In a reverse motion, the closing trigger can be reengaged to the trigger trigger.abstract a surgical instrument may include an end effector, an input drive shaft, a closure drive, and/or a firing drive. the end effector may comprise a jaw assembly including a first jaw member and a second jaw member. the end effector may compr
