    Abstract: An apparatus is configured to apply an adjunct material to at least one of a first stapling surface or a second stapling surface of a surgical stapler. The apparatus includes a contact structure defining a longitudinal axis and an expansion mechanism. The contact structure includes a first contact member configured to support a first portion of the adjunct material and a second contact member movably coupled with the first contact member that is configured to support a second portion of the adjunct material. The first and second contact members are configured to move away from one another in opposing directions to apply the first portion of the adjunct material to the first stapling surface and the second portion of the adjunct material to the second stapling surface. The expansion mechanism is selectively operable to transition the contact structure from a non-expanded state toward the expanded state.

    Abstract: A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.

    Abstract: A robotic surgical system that comprises a closure system. The closure system comprises a first pinion drivingly coupled to a first motor, a second pinion drivingly coupled to a second motor, and a closure gear selectively driven by the first pinion and the second pinion. The robotic surgical system further comprises a control circuit configured to implement a motor crosscheck operation. The control circuit is configured to receive a first parameter indicative of a first torque generated by the first motor, receive a second parameter indicative of a second torque generated by the second motor, compare the first parameter to the second parameter, and transmit a signal to a communication device, wherein the signal is based on the comparison and indicative of a status of the closure system.

    Abstract: A robotic surgical system includes a robotic arm, a surgical device coupled with the robotic arm and configured to extend through a body wall of a patient, and a controller in communication with the robotic arm. The controller is configured to determine a position of the surgical device relative to the patient. The controller is also configured to acknowledge a maximum allowable metric associated with the body wall at the determined position, and determine a metric associated with the body wall at the determined position. The controller is furthermore configured to drive the robotic arm to manipulate the surgical device such that the determined metric does not exceed the maximum allowable metric.

    Abstract: An apparatus is provided for applying an adjunct element to at least one of opposing first and second jaws of an end effector of a surgical stapler, wherein each of the first and second jaws includes a stapling surface and an external surface opposed from the respective stapling surface. The apparatus comprises: (a) a platform configured to be positioned between the first and second jaws of the end effector; (b) an adjunct element positioned on the platform; and (c) at least one closure surface opposed from the platform, wherein the at least one closure surface is configured to mechanically engage the external surface of at least one of the first or second jaws to thereby transition the end effector from an open state toward a closed state for placing the respective stapling surface of the at least one of the first or second jaws in contact with the adjunct element.
