    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.

    摘要： An apparatus comprises an end effector, an elongate shaft, and a handle assembly. The shaft includes an articulation section that is operable to deflect the end effector away from the longitudinal axis of the shaft. The handle assembly includes a rotary member positioned within an intermediate section of the handle assembly. The rotary member is rotatable about an axis that is parallel to the longitudinal axis of the shaft. The rotary member is operable to control the articulation section of the shaft. The rotary member may include opposing thread sections that simultaneously drive lead screws in opposite longitudinal directions, to thereby control the articulation section. The shaft may be rotatable relative to the handle assembly, and the apparatus may selectively lock or resist such rotation based on the articulation state of the articulation section.

    摘要： An apparatus for stapling tissue includes a head assembly, a handle actuator in communication with the head assembly, and a staple cartridge. The head assembly is operable to drive a plurality of staples in response to actuating the handle actuator. The staple cartridge is in communication with the head assembly. The staple cartridge comprises a first annular ring of apertures and a second ring of apertures. The first annular ring of apertures includes apertures having a different size than the second annular ring of apertures, such that the apertures accommodate staples having different crown lengths. The staples may include pledgets that are configured to provide a greater staple footprint.

    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.
