Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A surgical tool, comprising: an end effector, comprising: a first jaw member; a second jaw member; and an I-beam member configured to translate in an axial direction to cam the first jaw member toward the second jaw member, said I-beam member connected to a threaded rotary drive member coupled to a rotary drive nut; a shaft assembly proximal to the end effector, wherein the end effector is configured to rotate relative to the shaft assembly; a ro…
