    Abstract: An apparatus comprises an end effector, a shaft assembly, and a drive assembly. The end effector comprises needle receiving arms operable to grasp a needle. The drive assembly comprises drive members that are rotatable about respective drive axes that are perpendicular to the axis of the shaft assembly. The drive assembly is operable to drive the needle receiving arms to selectively engage and disengage the needle; and to selectively pass the needle from one needle receiving arm to the other needle receiving arm. The drive assembly provides an interface to a controller that is operable via a remote user interface. The drive assembly may include helical gears, clutch assemblies, a rack and pinion, or other components to convert motion of the drive members into motion at the end effector.

    Abstract: A suture needle driving instrument comprises a shaft and an end effector. The end effector is located at the distal end of the shaft and includes a pair of needle grasping arms. Each grasping arm extends along a respective arm axis. The grasping arms are operable to drive a suture needle along a rotational path about an axis, such as one of the arm axes, that is offset from the central longitudinal axis of the shaft. The rotational path may be perpendicular to the axis of the shaft. A needle driven by the end effector may have an arc radius that is greater than the radius of the shaft. At least one of the needle grasping arms may include a dogleg feature positioning a distal portion of the grasping arm outside the radius of the shaft. The instrument may be used through a trocar during minimally invasive surgery.

    Abstract: An apparatus comprises a shaft, a needle throwing arm, and a needle receiving arm. The arms are movable asynchronously along planes that are substantially parallel to a longitudinal axis defined by the shaft. The arms selectively engage a surgical needle, such that the throwing arm may pass the surgical needle through tissue for receipt by the receiving arm, and the receiving arm may then pass the surgical needle back to the throwing arm for additional stitching. The arms may pivot about a common pivot. Such versions may include a single actuator for both arms or separate actuators for the arms. The arms may also pivot about their own respective axles, which may facilitate a forward reset motion for a needle, allowing the needle to continue travelling along a circular path in a single direction to create several stitches. The apparatus may also convert reciprocating movement of actuators into rotational motion.

    Abstract translation: 一种装置包括轴，针投掷臂和针接收臂。 臂可以沿着基本上平行于由轴限定的纵向轴线的平面异步移动。 手臂选择性地接合手术针，使得投掷臂可以将手术针穿过组织以便接收臂接收，并且接收臂然后可以将外科手术针返回到投掷臂以用于额外的缝合。 手臂可绕枢轴转动。 这种版本可以包括用于臂的单个致动器或用于臂的单独致动器。 臂也可以围绕它们各自的轴枢转，这可以促进针的向前复位运动，允许针沿着单个方向的圆形路径继续行进以产生几个针迹。 该装置还可以将致动器的往复运动转换成旋转运动。
