Proximal steering cable adjustment

摘要

A steering control unit for a cable-actuated bending neck of an elongated probe has a cable slack adjustment mechanism disposed on the proximal end of the unit. This permits field service of the probe and allows for a watertight housing. The adjustment mechanism employs hollow adjuster screws that are threaded into the proximal side of the toothed racks of the control unit. Rack travel adjustment is also accomplished using hollow adjusting screws.
