Abstract
A robotic surgical system may include a cannula attachment device or cannula mount having a locking mechanism configured to pivot between an unlocked position and a locked over-center position. The locking mechanism may actuate a clamp or other feature that is configured to move between a closed position and an open position. The clamp may include a locating structure with one or more tapered surfaces that is configured to mate with a corresponding structure disposed on a portion of a cannula when the cannula is positioned in the cannula attachment device. The locating structure may guide the cannula into the attachment device, as well as assist with orientating the cannula relative to the attachment device.
Claims20
An apparatus for attaching a cannula to a robotic surgical system, the apparatus comprising:
- a first clamp component configured to pivot between an open position and a closed position;
- a second clamp component spaced from the first clamp component, the first and second clamp components defining a region configured to receive a portion of the cannula, the first and second clamp components configured to retain the portion of the cannula in the region when the first clamp component is in the closed position;
- a locking component coupled to the first clamp component and configured to pivot the first clamp component between the open position and the closed position;
- and
- a locating structure disposed on at least one of the first clamp component and the second clamp component configured to mate with a corresponding structure disposed on the portion of the cannula.
A method, comprising:
- positioning a locking component of an attachment apparatus for a cannula in an unlocked position, wherein the locking component is operatively coupled to a first clamp component and configured to pivot the first clamp component between an open position and a closed position, wherein the first clamp component is positioned in the open position when the locking component is positioned in the unlocked position;
- inserting a portion of the cannula into a region between the first clamp component and a second clamp component;
- and
- moving the locking component from the unlocked position to a locked over-center position to pivot the first clamp component to the closed position, the first and second clamp components configured to retain the portion of the cannula in the region when the first clamp component is in the closed position.
