    • A surgical tool for deploying an anastomotic ring comprises a handle and a ring deployment mechanism at the distal end of a shaft. The ring deployment mechanism has a distal portion and a proximal portion, and is moveable from an unactuated position to an actuated position to deploy an anastomotic ring. To prevent tissue from becoming trapped in the deployment mechanism during insertion or extraction of the tool, distal and proximal sheaths are configured to cover distal and proximal portions of the ring deployment mechanism, respectively. An actuation mechanism in the handle permits advancement of the distal sheath and actuation of the distal portion of the ring deployment mechanism with a single movement of a first actuator slider. The actuation mechanism also permits retraction of the proximal sheath and actuation of the proximal portion of the ring deployment mechanism with a single movement of a second actuator slider.
    • 用于展开吻合环的手术工具包括在轴的远端处的手柄和环展开机构。 环展开机构具有远侧部分和近端部分,并且可从未致动位置移动到致动位置以展开吻合环。 为了防止组织在插入或拔出工具期间被捕获在展开机构中,远端和近侧护套分别被构造成覆盖环展开机构的远侧和近端部分。 手柄中的致动机构允许使用第一致动器滑块的单个运动使远端护套的前进和环形展开机构的远端部分的致动。 致动机构还允许第二致动器滑块的单个运动来近端护套的缩回和环形展开机构的近侧部分的致动。
