1. A robotic surgical system comprising:
a robotic manipulator that includes a mounting fixture defining a longitudinal channel; and
a surgical tool removably coupleable to the mounting fixture and including:
a tool housing mateable 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,
wherein 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, and
wherein the one or more retention tabs engage an exterior surface of the mounting fixture when moved to the deployed state.
