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.
