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.
