Abstract: A surgical end effector assembly includes first and second jaw members configured to grasp tissue. Each of the first and second jaw members includes a proximal flange portion and a distal body portion. The proximal flange portions are pivotably coupled to one another to move the distal body portions between a spaced-apart position and an approximated position.

Abstract: 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.

Abstract: 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.

Abstract: An end effector assembly includes a clevis having first and second spaced-apart arms, a ceiling, a floor, pivot and cam pins extending between the arms, and first and second jaw members. Each jaw member includes a proximal portion and a distal body extending distally from the clevis. The proximal portion of the first jaw member includes a first flag disposed between the first and second arms of the clevis, operably coupled to both the pivot pin and the cam pin, extending vertically at least partially through openings defined within the ceiling and floor. The proximal portion of the second jaw member includes second and third flags disposed between the first and second arms of the clevis in spaced-apart relative to one another and between the ceiling and the floor. The second and third flags are fixedly engaged to the clevis.

Abstract: 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.

Abstract: An end effector assembly of a robotic surgical instrument includes a clevis, first and second jaw members supported by the clevis, and a cam bar configured to move the first and second jaw members between an open state and a closed state.

Abstract: A robotic surgical instrument includes a housing, a shaft assembly extending distally from the housing, and an end effector assembly. The shaft assembly has a proximal segment coupled to the housing, a clevis supporting the end effector assembly, and an articulating link pivotably coupled to and interconnecting the proximal segment and the clevis such that the end effector assembly is configured to articulate relative to the proximal segment via the articulating link in at least two directions.

Abstract: An end effector assembly of a robotic surgical instrument includes a distal segment and first and second jaw members supported by the distal segment. The distal segment defines an elongate slot therein. The first jaw member has a proximal flange portion received in the elongate slot of the distal segment, and the second jaw member has a proximal flange portion received in the distal segment. The proximal flange portions of each of the first and second jaw member are pinned to the distal segment.

Abstract: A jaw member for a surgical instrument includes an outer housing having a sealing plate operably coupled thereon including an upper knife channel defined therethrough and extending therealong. A pair of opposing jaw flanges is configured to operably couple to a corresponding pair of jaw flanges of an opposing jaw member. An insulative insert is disposed within the outer housing and includes opposing sidewalls and a connector portion which define an engagement channel and a lower knife channel in vertical registration with the upper knife channel, the upper and lower knife channels configured to receive a knife of a knife assembly, the engagement channel configured to receive a tube of the knife assembly. A top plate is engaged between the jaw flanges, a portion of the top plate is configured to extend across the engagement channel and retain the tube within the engagement channel during translation of the knife assembly.
