Abstract: A robotic surgical system includes a robotic manipulator that includes a mounting fixture defining a longitudinal channel, and a surgical tool removably coupleable to the mounting fixture. The surgical tool including a tool housing matable with the mounting fixture, an elongate shaft extending from the tool housing and receivable within the channel, and a latching mechanism provided on the elongate shaft and comprising one or more retention tabs biased radially outward with one or more biasing members. The one or more retention tabs are movable between a deployed state, where the one or more retention tabs protrude radially outward through a corresponding one or more slots to engage the mounting fixture, and a retracted state, where the one or more retention tabs are urged radially inward through the one or more slots to disengage the mounting fixture.

Abstract: A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.

Abstract: Robotic surgical tools can incorporate a latching mechanism as a secondary fastener to maintain operable coupling between the robotic surgical tool and a mounting fixture of a robotic manipulator. Such robotic surgical tools may comprise: a tool housing, an elongate shaft extending from the tool housing, and a latching mechanism arranged on the elongate shaft. The latching mechanism comprises one or more retention tabs that are biased radially outward with one or more biasing members. The one or more retention tabs are configured to transition between a retracted state and a deployed state under influence of a biasing force supplied by the one or more biasing members. In the deployed state, the one or more retention tabs are positioned to engage an exterior surface of a mounting fixture of a robotic manipulator. In the retracted state, the one or more retention tabs are positioned to disengage from the mounting fixture.
