    • The present disclosure relates to a ligating instrument and end effector assemblies for use in laparoscopic tubal ligation procedures. The ligating instrument includes an integral grasping assembly and an integral end effector actuator and is configured to perform a ligating procedure by operation of a single hand of a user. The ligating instrument includes an integral grasper assembly for grasping a tubular tissue section and removable end effector or suture deployment mechanism for holding open a suture to be positioned about the tubular section. The grasper is configured to draw the tubular section into the open loop of suture material and cinch the suture material about the tubular tissue section. A rotator knob may be provided to orient grasper members associated with the grasper assembly relative to the tissue section. An alternative end effector is provided to removably mount on the distal end of the ligating instrument and to cut that part of the tubular tissue section which needs to be removed after the tubular tissue section has been ligated. A relatively soft over mold section may be provided to at least partially enclose the handle of the ligating instrument in order to provide comfort and facilitate a rsurer grip of the instrument.
    • 本公开涉及一种用于腹腔镜输卵管结扎术的结扎器械和末端执行器组件。 结扎器具包括一体式把持组件和整体式端部执行器致动器,并且被配置为通过使用者的单手操作执行结扎过程。 结扎器具包括用于抓住管状组织部分和可移除的末端执行器或缝合线展开机构的整体抓持器组件,用于保持打开缝合线以围绕管状部分定位。 抓紧器构造成将管状部分拉入缝合线材料的开环,并围绕管状组织部分束紧缝合材料。 可以提供旋转器旋钮以相对于组织部分定向与抓紧器组件相关联的抓紧构件。 提供替代的末端执行器以可拆卸地安装在结扎器械的远端上,并且在管状组织部分已被连接之后切割需要移除的管状组织部分的那部分。 可以提供相对柔软的模具上部分以至少部分地包围结扎器械的手柄,以便提供舒适性并且便于器械的握持。
