    摘要: A stretchable buttress assembly is associated with surgical staples deployable into tissue from a surgical stapler having a longitudinal axis. The buttress assembly includes a planar fabric and a bioabsorbable adhesive. The planar fabric also has fibers that are either substantially unaligned with the longitudinal axis of the surgical stapler or substantially aligned with the longitudinal axis of the surgical stapler. The bioabsorbable adhesive is applied to the first side and/or the second side of the planar fabric and is configured to adhere the stretchable buttress assembly to an end effector of the surgical stapler. The buttress assembly is substantially stretchable in one direction. In some versions the buttress assembly is stretchable in a direction parallel to the longitudinal axis. In some versions the buttress assembly is stretchable in a direction perpendicular to the longitudinal axis.

    摘要: A sterile barrier is provided for use with a surgical robotic system. The sterile barrier can include a housing configured to mate with a tool driver mated to a robotic arm and to removably receive a surgical tool. The housing of the sterile barrier has a sterile flexible fabric extending therefrom such that the housing and the flexible fabric are formed in more than one plane and define a sterile side on which the surgical tool is disposed and a non-sterile side on which the tool driver and the robotic arm are disposed. The housing has an opening for receiving the surgical tool. The housing can have at least one electrical contact configured to operably mate with at least one complementary electrical contact on at least one of the tool driver and the robotic arm.

    摘要: Devices, systems, and methods are provided in which movement of a tool is controlled based on sensed parameters. In one embodiment, an electromechanical tool is provided having an instrument shaft and an end effector formed thereon. The electromechanical tool is configured to be mounted on an electromechanical arm, and the electromechanical tool is configured to move with or relative to the electromechanical arm and perform surgical functions. A controller is operatively coupled to the electromechanical arm and the electromechanical tool and is configured to retard advancement of the electromechanical tool toward a tissue surface based on a sensed amount of displacement of a tissue surface, a strain on the tissue of the patient, the temperature of the electromechanical tool, or the like.
