A surgical suturing instrument including a handle assembly, an elongate member extending distally from the handle assembly and an end effector attached to the distal end of the elongate member. The end effector may include a first jaw member movable relative to a second jaw member between an open position and an approximated position for grasping tissue. Each of the jaw members define a knife slot, a first needle slot, and a second needle slot extending along a longitudinal axis of the end effector. The end effector also includes a knife assembly and an upper assembly pivotably coupled to an upper knife flange of the knife assembly. The upper assembly includes an upper bellcrank, a first needle, a first suture passing through a first aperture defined by the first needle, a second needle and a second suture passing through a second aperture defined by the second needle. |

1. An end effector for use with a surgical suturing instrument, the end effector comprising:
a first jaw member movable relative to a second jaw member between an open position and an approximated position for grasping tissue, each of the first and second jaw members defining a knife slot, a first needle slot, and a second needle slot, the knife slot, the first needle slot, and the second needle slot extending along a longitudinal axis of the end effector; a knife assembly configured to advance through the first jaw member and the second jaw member, the knife assembly including an upper knife flange, a lower knife flange, and a cutting element between the upper knife flange and the lower knife flange; and an upper assembly including:
an upper bellcrank pivotably coupled to the upper knife flange;a first needle pivotably coupled to a first end of the upper bellcrank, the first needle defining a first aperture and being configured to advance through the first needle slot;a first suture passing through the first aperture;a second needle pivotably coupled to a second end of the upper bellcrank, the second needle defining a second aperture and being configured to advance through the second needle slot; anda second suture passing through the second aperture. |
