  • Patent number: 11419603
    Abstract: Articulating surgical instruments are disclosed. In one embodiment, a surgical instrument may include an elongated shaft assembly including an articulable portion moveable between a non-articulated configuration and an articulated configuration. First and second articulating shafts of the elongated shaft assembly may be coaxially arranged and axially fixed at an attachment point located distally from the articulable portion. Proximal portions of the first and second articulating shafts may be displaceable in opposing directions to articulate the articulable portion from the non-articulated configuration to the articulated configuration. In another embodiment, an articulation control may be movable from a first position to a second position to move an articulation lock from a locked configuration to an unlocked configuration to selectively permit articulation of a surgical instrument. The articulation lock also may be movable from the second position to a third position to articulate the surgical instrument.

  • Patent number: 11413129
    Abstract: An implantable prosthesis for repairing a defect in a muscle or tissue wall. The prosthesis comprises a body of biologically compatible prosthetic material having a preformed three-dimensional contoured shape that independently assumes a three-dimensional curved shape configured to conform to the muscle or tissue wall. The body may be formed of a mesh fabric employing a knit construction. The body may be configured with one or more mechanical characteristics, individually or in any combination, having defined properties which may enhance the ability of the prosthesis to be handled in a surgical, robotic environment while meeting the performance and physical characteristics for soft tissue repair and reconstruction. One or more visual indicia may be provided to facilitate positioning and/or placement of the prosthesis at the muscle or tissue wall.

  • Publication number: 20220160351
    Abstract: Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a magnetic preload lock-out to place the follower in a zero-load state in which the follower does not apply a preload to the fasteners.

  • Patent number: 11045175
    Abstract: Surgical devices for use with robotic surgical systems and their methods of use are described. In some embodiments, the surgical device may include an actuator that interfaces with an end effector of an arm of a robotic surgical system. An output from the end effector may actuate the actuator to perform an operation of the surgical device. In some embodiments, the surgical device may include a retainer that retains at least a portion of the surgical device on a distal portion of the arm of the robotic surgical system during actuation. In other embodiments, the surgical device may include a portion that is engaged by a second robotic surgical arm to hold at least a portion of the surgical device stationary relative to the robotic surgical arm engaged with the actuator of the surgical device.
