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.
