    • A surgical instrument that is operable to deploy an anastomotic ring device comprises a proximal portion (200) and a distal portion (300). The distal portion comprises a ring deployment mechanism (26), which is configured to receive and deploy an anastomotic ring (14). The proximal portion comprises a mechanism that is operable to remotely actuate the ring deployment mechanism. The distal portion is removable from the proximal portion. The distal portion may be selectively engaged with the proximal portion by a series of annular flanges (114) and clamp arms (110) that are configured to engage the annular flanges. The ability to remove the distal portion of the instrument permits the replacement of the ring deployment mechanism without requiring the replacement of the instrument in its entirety.
    • 可操作以展开吻合环装置的外科器械包括近端部分(200)和远端部分(300)。 远侧部分包括环形展开机构(26),其配置成接收和展开吻合环(14)。 近端部分包括可操作以远程致动环展开机构的机构。 远端部分可从近端部分移除。 远端部分可以通过一系列环形凸缘(114)和夹紧臂(110)选择性地与近端部分接合,该夹紧臂构造成与环形凸缘接合。 除去仪器的远端部分的能力允许更换环部署机构,而不需要更换仪器的整体。

    • A surgical instrument (30) comprises a handle (32) and an elongate shaft (34), and is operable to remove an anastomotic ring device from a patient. The elongate shaft houses a plurality of ring engaging fingers (38). Each of the fingers comprises sheath (40) housing a wire (46) having a hook (48) at its distal end. Each hook may be advanced beyond the distal end of a respective sheath to engage petals on an anastomotic ring device. Subsequent proximal retraction of the hooks secures the anastomotic ring device to the ring engaging fingers. With the anastomotic ring device secured to the ring engaging fingers, the fingers may be drawn together to collapse the anastomotic ring device from an actuated, hollow rivet-shaped configuration to an unactuated, cylindrically-shaped configuration. The surgical instrument may then contain the collapsed anastomotic ring device, thereby facilitating removal of the anastomotic ring device from the patient.
    • 外科器械(30)包括手柄(32)和细长轴(34),并且可操作以从患者移除吻合环装置。 细长轴容纳多个环接合指状物(38)。 每个指状物包括容纳在其远端具有钩(48)的线(46)的护套(40)。 每个钩可以超出相应护套的远端,以接合吻合环装置上的瓣。 钩的随后的近端缩回将吻合环装置固定到环接合的手指。 使用固定到环接合指状物的吻合环装置,手指可以被牵拉在一起以将吻合环装置从致动的中空铆钉形状构造压缩成未致动的圆柱形构造。 然后,外科器械可以包含塌陷的吻合环装置,从而便于从患者移除吻合环装置。
