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: Implementations relate to detection and mitigation of potential collisions with a user control system. In some implementations, a method includes detecting an object in a sensing field of a sensor of a user control system, and the user control system includes a control input device. The control input device is in a controlling mode in which manipulation of the control input device activates a function of a manipulator device. The method includes determining that the object is an unidentified object and determining a characteristic of the object including a location with respect to the user control system, a velocity, or a trajectory. The method determines whether the characteristic of the object satisfies a condition corresponding to the characteristic, and exits the controlling mode in response to determining that the object is an unidentified object and that the characteristic satisfies the corresponding condition.

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.

Abstract: An exemplary image viewing system includes a display device configured to emit visible light representative of an image provided for display by the image viewing system, an infrared light source configured to emit infrared light, a viewing lens, and a black glass mirror provided between the infrared light source and the viewing lens. The black glass mirror comprises black glass and a coating on an outer surface of the black glass. The coating is configured to reflect a first portion of the visible light emitted from the display device towards the viewing lens, pass a second portion of the visible light emitted from the display device to the black glass, and pass a portion of the infrared light emitted from the infrared light source toward the viewing lens. The black glass is configured to pass the portion of the infrared light and absorb the second portion of the visible light.

Abstract: Methods for minimally invasive electro-surgical systems are disclosed. One method includes determining if an input device is selected at a control console. If the input device is selected then, providing feedback to a user of the selection of the input device, delaying a first predetermined period of time for the user to receive the feedback, determining if the input device is deselected, and if not deselected, then activating an electrosurgical device to couple energy to tissue. If deselected, the method skips activation of the electrosurgical device. While active, a method includes determining if the input device is deselected, and if so, then deactivating the electrosurgical device, determining if the input device is reselected and if the input device is not reselected, then waiting and determining if a second predetermined period of time has lapsed prior to reselection of the input device and if not, then repeating the reselected determining step.

The first colored border portion in the GUI indicates that the first electrosurgical tool is controlled by a first master grip of the surgeon console and the second colored border portion indicates the tool type of the second tool controlled by a second master grip of the surgeon console.
