Abstract: An end effector assembly of a surgical instrument includes a clevis defining a longitudinal axis and including first and second arms spaced-apart relative to one another and first and second jaw members supported by the clevis. At least one of the jaw members is movable relative to the other and the clevis between a spaced-apart position and an approximated position for grasping tissue between the jaw members. The clevis includes first and second locating features on outwardly-facings sides of the first and second spaced-apart arms, respectively. The first and second locating features are configured to facilitate engagement and alignment of the end effector assembly within a test fixture.

Abstract: A surgical end effector assembly includes a clevis, first and second jaw members, and first and second lead wires. The clevis defines first and second arms spaced-apart relative to one another and extending from a proximal body and a finger extending from the proximal body at least partially between the arms. The finger defines a mouth at a free distal end thereof and a channel in communication with the mouth. The jaw members include proximal flange portions at least partially disposed between the arms, distal body portions extending distally from the clevis, and electrically conductive tissue contacting surfaces. At least one jaw member is movable to grasp tissue. The lead wires are connected to the tissue contacting surfaces and extend proximally from the distal body portions of the first and second jaw members through the mouth and into the channel of the finger of the clevis.

Abstract: A jaw member of an electrosurgical instrument includes a U-shaped structural frame defining a cavity therein and extending therealong configured to receive at least a portion of an insulative spacer therein such that the insulative spacer extends distally therefrom. The insulative spacer includes a tapered fin at a distal end thereof. A tissue treating plate is disposed on the face of the insulative spacer, the tissue treating plate is adapted to connect to a source of energy to treat tissue therewith. The tapered fin is configured to extend to and support a distal end of the tissue treating plate.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is operably coupled to the instrument housing and is configured to move the jaw members. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members, the handle having a lever configured to cooperate with the input to control the jaw members relative to movement of the lever. The lever moves between a homing position and a first position correlating to the jaw members closing with a pressure therebetween in the range of about 0.1 kg/cm2 to about 2 kg/cm2. The lever further movable to a seal position correlating to the jaw members closing about tissue with a pressure between about 3 kg/cm2 to about 16 kg/cm2 for sealing.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is configured to move the jaw members and is configured to operably couple to a torque sensor that measures the torque of the input during rotation thereof. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the movement of the jaw members. A housing having a lever operably coupled thereto, houses components therein configured to operably connect to the input such that movement of the lever correlates to movement of the jaw members. The components are configured to regulate the resistance of the lever in response to the feedback from the torque sensor.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing with a shaft and first and second jaw members attached thereto movable to grasp tissue. An input is coupled to a jaw drive rod and is configured to move the jaw members. A strain gauge is coupled to the jaw drive rod and is configured to measure an amount of strain thereon and communicate the amount of strain to a robotic controller. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members. The handle includes a housing having components therein and a lever operably associated therewith such that movement of the lever relative to the housing correlates to movement of the jaw members. The components are configured to operably regulate the resistance of the lever in response to the amount of strain from the strain gauge.

Abstract: A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to 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.
