摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
摘要翻译：特别适用于内窥镜手术的手术吻合器和切断器具有一个手柄，其产生分开的关闭和发射运动来致动末端执行器。特别地，手柄产生多个点火冲程，以便减少火焰所需的所需力量（即订书钉和切断）末端执行器。连接的传动减少了所需的手柄纵向长度，而在拉直时用于烧制，实现了刚性的强结构。牵引偏压发射机构与防抱死机构协作，避免了在驱动该矫直联接架时的装订，其中锁定机构防止在击发期间释放闭合触发器。此外，外部指示器向外科医生反馈射击进展的程度以及提供手动回缩能力。
