    Abstract: An articulation joint includes proximal links, distal links, and intermediate links connecting the proximal and distal links. The articulation joint has a straight configuration along a straight longitudinal axis, a first bent configuration when the articulation joint bends toward a first side of the longitudinal axis, and a second bent configuration when the articulation joint bends toward a second side of the longitudinal axis, opposite to the first side. When the articulation joint is in the straight configuration, a first gap is defined at the first side between adjacent proximal links, and the adjacent proximal links contact each other at the second side, a second gap is defined at each of the first side and the second side between adjacent distal links, and a third gap is defined at the first side between adjacent intermediate links, and adjacent intermediate links contact each other at the second side.

    Abstract: A linkage assembly for a medical device may comprise: a rotatable member configured to rotate about a rotation axis; a piston; and a connecting rod rotatably connected to the rotatable member and the piston and movable along a range. A first end of the range may correspond to an initial position of a distal member movable by the linkage assembly, and a second end of the range may correspond to a final position of a distal member. In a first configuration of the connecting rod, at the first end of the range, a proximal end of the connecting rod may be offset from a longitudinal axis by a first amount, wherein the longitudinal axis is perpendicular to the rotation axis; In a second configuration of the connecting rod, at the second end of the range, the proximal end of the connecting rod may be offset from the longitudinal axis by a second amount. The second amount may be less than two-thirds of the first amount.

    Abstract: An actuation mechanism for a medical device comprises: a rotatable member configured to rotate about a rotational axis and a spring, coupled directly or indirectly to the rotatable member. The spring is configured to move from a first configuration to a second configuration. In the first configuration, a longitudinal axis of the spring has a first angle with respect to a lever arm of the rotatable member. In the second configuration, a longitudinal axis of the spring has a second angle with respect to the lever arm of the rotatable member.

    Abstract: A medical device includes a handle including an axle, a device shaft extending from the handle to a distal end, and a control device. The control device is coupled to the handle, and the control device includes a knob. The knob is rotatable relative to the handle. The control device also includes a control shaft extending from the knob, at least one spring clutch including two legs, and a spool. The spool is rotatable relative to the axle. The control device also includes one or more wires coupled to the spool. Rotation of the knob is configured to rotate the control shaft, causing the at least one spring clutch to loosen, the spool to rotate, and the one or more wires to move.
