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 jaw member of a surgical instrument includes a structural frame, an insulative spacer supported on the structural frame, an electrically conductive tissue contacting plate supported on the insulative spacer, and a lead wire. The spacer defines a pocket at an upper portion thereof and includes a channel extending from the pocket, through the spacer, to a bottom portion of the spacer. The channel defines a substantially U-shaped configuration having first and second radiused corners at the bottom portion of the spacer. The lead wire is attached to an underside of the plate at an attachment point within the pocket and extends distally from the attachment point into the channel, through the channel, over the first and second radiused corners, and proximally from the jaw member. The lead wire is adapted to connect to a source of energy to energize the plate for treating tissue.

Abstract: A surgical instrument for use with a robotic surgical system includes a shaft extending distally from a housing and first and second jaw members disposed at a distal end of the shaft. The surgical instrument also includes a knife blade configured to cut tissue and a drive input configured to receive a rotational input from a robotic surgical system to drive rotation of an input shaft and translate the knife blade. The surgical instrument also includes a knife blade lock configured to move between a locked position to prevent rotation of the drive input, and an unlocked position such that the drive input is permitted to rotate in response to receiving the rotational input to drive rotation of the input shaft. The surgical instrument also includes a spring configured to bias the knife blade lock into the locked position.

Abstract: A surgical instrument includes a housing, first, second, and third actuators operably coupled to the housing, an at least partially semi-rigid shaft extending distally from the housing, an end effector assembly disposed at a distal end of the shaft, and first, second, and third bars extending through the shaft in non-coaxial arrangement. The first bar is operably coupled between the first actuator and the end effector assembly such that actuation thereof effects manipulation of the end effector assembly. The second bar is operably coupled between the second actuator and a first deployable component such that actuation thereof effects deployment of the first deployable component relative to the end effector assembly. The third bar is operably coupled between the third actuator and a second deployable component such that actuation thereof effects deployment of the second deployable component relative to the end effector assembly.

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: An electrosurgical forceps includes a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. Each jaw member has a jaw housing and an electrosurgical seal plate. The first jaw member is movable relative to the second jaw member from an open configuration to a clamping configuration. The first jaw member includes an elongated channel defined in its respective jaw housing and extends along a length thereof. A drive assembly operably couples to the first jaw member via a drive rod that is engageable with the elongated channel to move the first jaw member from the open configuration to the clamping configuration and to provide a closure force between the jaw members when the jaw members are in the clamping configuration.

Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

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 method of determining the distal throw of a knife blade of a robotic surgical instrument includes selectively engaging an end effector onto a housing of a robotic surgical instrument homing a knife blade. The method further includes initiating an end stop detection algorithm including: actuating a knife drive coupler to advance the knife blade distally through a knife channel defined within the end effector; calculating the running torque average of the knife drive coupler as the knife blade translates through the knife channel; determining a spike above the running torque average within a predetermined threshold and recording the position of the knife blade as a maximum distal throw of the knife blade; retracting the knife blade to determine an offset position from the maximum distal throw of the knife blade; and recording the offset position of the knife blade for subsequent usage.
