    摘要： A surgical instrument includes an elongated shaft including an articulating segment. A jaw assembly extends from a distal segment of the elongated shaft. A first jaw member can be actuated between a closed configuration and an open configuration. An articulation cable assembly includes a first articulation cable including a first extending portion, a second extending portion spaced apart from the first extending portion, and a loop portion connecting distal ends of the first and second extending portions of the first articulation cable. A first ferrule is positioned about the loop portion of the first articulation cable. A second articulation cable includes a first extending portion, a second extending portion spaced apart from the first extending portion, and a loop portion connecting distal ends of the first and second extending portions of the second articulation cable. A second ferrule is positioned about the loop portion of the second articulation cable.

    摘要： A surgical instrument includes a housing, an articulating shaft, and an end effector assembly extending from the articulating shaft. Tensioning a first articulation cable and slackening a second articulation cable articulates the end effector assembly in a first direction and the opposite articulates the end effector assembly in a second, opposite direction. An articulation mechanism includes first and second capstans including proximal end portions of the first and second articulation cables at least partially wound thereabout. The first capstan is configured to rotate in a first direction to wind up the proximal end portion of the first articulation cable to tension the first articulation cable and in a second direction to unwind the proximal end portion of the first articulation cable to slacken the first articulation cable. The second capstan acts in an opposite manner to tension and slacken the second articulation cable.

    摘要： A surgical end effector assembly includes first and second jaw members configured to grasp tissue. At least one of the jaw members defines a channel. A cutting element reciprocates through the channel to cut grasped tissue. The cutting element may include a first bevel defined along a first portion of a distal edge on a first side surface of the cutting element and a second bevel defined along a second portion of the distal edge on a second side surface of the cutting element. The first and second portions of the distal edge are sharpened to facilitate cutting tissue upon distal advancement of the cutting element. Alternatively or additionally, the cutting element may include a proximal body and a distal fin defining a height greater than a height of the proximal body and including a thinned portion defining a depression within a first side surface thereof.
