1. A linkage assembly for a medical device, the linkage assembly comprising:
a rotatable member configured to rotate about a rotation axis;
a plunger; and
a connecting rod rotatably connected to the rotatable member and the plunger and movable along a range, wherein a first end of the range corresponds to an initial position of a distal member movable by the linkage assembly, and a second end of the range corresponds to a final position of the distal member,
wherein the connecting rod consists of a first segment, a second segment, and a third segment, wherein the second segment is disposed between the first segment and the third segment, wherein the first segment is movably coupled to the rotatable member, wherein the third segment is movable coupled to the plunger, wherein each of the first segment and the third segment are angled relative to the second segment,
wherein a first angle between the first segment and the second segment on a first side of the connecting rod is less than a second angle between the second segment and the third segment on the first side of the connecting rod,
wherein, in a first configuration of the linkage assembly, at the first end of the range, a proximal end of the connecting rod is offset from a longitudinal axis by a first distance, wherein the longitudinal axis is perpendicular to the rotation axis, wherein, in the first configuration, a proximal end of the connecting rod is offset from the longitudinal axis of the linkage assembly by approximately 70 degrees, and wherein the second segment is transverse to the longitudinal axis;
wherein, in a second configuration of the linkage assembly, at the second end of the range, the proximal end of the connecting rod is offset from the longitudinal axis by a second distance, wherein the second distance is less than two-thirds of the first distance, wherein the proximal end of the connecting rod is offset from the longitudinal axis of the linkage assembly by approximately 160 degrees, and wherein the second segment is transverse to the longitudinal axis.
