Abstract: A cannula mount for a surgical system includes a body configured to receive a portion of a cannula in a mounted state at the cannula mount; a pair of clamping components coupled to the body and configured to clamp the portion of the cannula in the mounted state of the cannula; and a latch assembly pivotably coupled to the body and slidably coupled to a clamping component of the pair of clamping components. At least one of the pair of clamping components is pivotable relative to the body to move the pair of clamping components between a first state to unclamp a cannula mounted at the cannula mount and a second state to clamp a cannula mounted at the cannula mount. Pivoting motion of the latch assembly relative to the body causes a portion of the latch assembly to slide along the clamping component and change a state of the pair of clamping components from an unlocked state to a locked state in the second state of the pair of clamping components.

Abstract: A cannula mount for a surgical system includes pivotable clamping arm with a first feature configured to engage a second feature of the cannula positioned in the cannula mount. The clamping arm comprises a cam follower surface. The cannula mount further comprises a latch member movable between at least a first position and a second position, and the latch member comprises a cam surface. On the condition that the latch member is in the first position, the cam surface engages the cam follower surface of the clamping arm to actuate the clamping arm to a closed position in which the first feature engages the second feature. On the condition the cam member is in the second position, the clamping arm is free to move to an open position in which the first feature does not engage the second feature. Devices and methods relate to cannula mounts.
