Abstract: A steering system for a medical device may include a first drive member having a central longitudinal axis; a central shaft extending through the first drive member; a control knob coupled to the first drive member; a braking knob coupled to the central shaft and including a first protrusion; and a brake shoe member coupled to the central shaft between the control knob and the braking knob. The first protrusion may be positioned within a first channel of the brake shoe member; the first protrusion may be configured to engage the brake shoe member to move a first arm of the brake shoe member radially outward towards a wall of the control knob when the braking knob is rotated in a first direction; and the first arm may be configured to move away from the wall when the braking knob is rotated in a second direction.

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. 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.

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.
