Abstract

A surgical instrument including a firing drive configured to selectively advance a firing member and / or cutting member relative to an end effector and, in addition, a reversing drive configured to selectively retract the firing member and / or cutting member relative to the end effector. In various embodiments, the surgical instrument can further include a switch including relatively movable first and second portions, wherein the first portion can be configured to operably disengage the firing drive from the firing member and, in addition, operably engage the reversing drive with the firing member. In at least one embodiment, the second portion can include a handle extending therefrom which can be motivated by the surgeon in order to engage the second portion with the first portion and movethe first portion into position.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part claiming priority to co-pending U.S. Patent Application Serial No. 11 / 821,277, filed June 22, 2007, entitled "SURGICALSTAPLING INSTRUMENTS," the entire contents of which are adopted by Incorporated by reference. technical field [0003] The present invention relates generally to a surgical stapling instrument, and more particularly, to a surgical stapler having a closure system for closing an end effector and a firing system for deploying the staples. Background technique [0004] As is known in the art, surgical staplers are commonly used to deploy staples into soft tissue to reduce or eliminate bleeding of the soft tissue, especially, for example, when the tissue is cut. A surgical stapler, such as an endoscopic cutter, for example, may include an end effector that is movable or articulated relative to an elongated shaft assembly. The end effector is generally used to fix ...
