Cannula adapter and surgical robot

A surgical robot, comprising a cannula adapter, wherein the cannula adapter is configured to hold a cannula of the surgical robot, and includes:

• an adapter body;
• a first guide rail extending along a first direction and fixedly disposed in the adapter body;
• at least one clamping jaw disposed in the adapter body and movably coupled to the first guide rail, wherein the at least one clamping jaw is translationally movable along the first guide rail between a first position and a second position without rotating relative to the adapter body;
• an operating actuation mechanism;
• and
• a follower mechanism including a movable member movably coupled to the adapter body and configured to be driven by the operating actuation mechanism to translationally move in a second direction transverse to the first direction without rotating relative to the adapter body;
• wherein the at least one clamping jaw is movably coupled to the movable member, such that translational movement of the movable member relative to the adapter body in the second direction drives the at least one clamping jaw to translationally move along the first guide rail, the at least one clamping jaw is in the first position when the movable member is in a third position, and the at least one clamping jaw is in the second position when the movable member is in a fourth position.

A cannula adapter for a surgical robot, comprising:

• an adapter body;
• a first guide rail extending along a first direction and fixedly disposed in the adapter body;
• at least one clamping jaw disposed in the adapter body and movably coupled to the first guide rail, wherein the at least one clamping jaw translationally movable along the first guide rail;
• an operating actuation mechanism;
• and
• a follower mechanism including a movable member movably coupled to the adapter body and configured to be driven by the operating actuation mechanism to translationally move in a second direction transverse to the first direction;
• wherein the movable member defines at least one slot, and each of the at least one clamping jaw has a roller movably received in a respective one of the at least one slot, the roller is movable relative to the movable member along a track on a plane defined by the first direction and the second direction, such that the at least one clamping jaw is moved along the first guide rail when the movable member is moved in the second direction.
