摘要：
A surgical instrument comprising a first jaw, a second jaw, and a firing member is disclosed. The firing member comprises one or more cams configured to position the first jaw relative to the second jaw. In various instances, one of the cams is oriented at a non-parallel angle relative to another cam in order to reduce strain within the cams. In certain instances, at least one of the cams comprises a leading projection and a trailing projection positioned behind the leading projection which are configured to engage the same jaw. The ends of the leading projection and the trailing projection are not attached to one another and can move relative to one another. In some instances, one or more of the cams has a plastically deformable or wearable feature configured to facilitate multiple uses of the surgical instrument.
