摘要： A suture needle driving instrument comprises a shaft assembly, an end effector, and a grasping actuation assembly. The end effector is located at the distal end of the shaft assembly and includes a pair of grasping arms. Each grasping arm comprises a respective pair of jaws. Each pair of jaws is operable to cooperate to grasp and release a suture needle. The grasping actuation assembly is operable to drive one jaw of each pair in one direction while simultaneously driving the other jaw of the pair in an opposite direction, to selectively grasp or release the suture needle. The shaft assembly includes two pairs of parallel concentric shafts, which form part of the actuation assembly. Each shaft pair is operable to drive a respective internal drive shaft having separate threaded regions with opposing pitch. The instrument may be used through a trocar during minimally invasive surgery.

摘要： 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.

摘要： A surgical needle includes a pair of ends, a mid-region extending between the ends, and at least one grasping feature configured for grasping by a suturing instrument. An end of a suture is secured to the mid-region of the needle in a manner such that the end of the suture defines an oblique angle with at least part of the centerline defined by the mid-region of the needle. The end of the suture may be disposed in a hollow portion of the needle. The grasping feature may include a notch such as a scallop. The suture may be pivotally coupled with the needle via a ball or pin. The needle may have one or more sharp points. The sharp point may include three converging cutting edges, at least two planar surfaces bounded by the three cutting edges, and a rounded surface bounded by two of the three cutting edges.

摘要： 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.
