An apparatus includes a body, a shaft assembly, a deflection actuation assembly, and a dilation catheter. The shaft assembly includes a rigid proximal portion and a flexible distal portion. The deflection actuation assembly includes a rotary actuator and a first translatable actuation member at least partially disposed within the first rotary actuator. A second translatable actuation member extends through the shaft assembly and couples the first translatable actuation member with the flexible distal portion of the shaft assembly. The first rotary actuator is rotatable about a longitudinal axis to thereby drive the first and second translatable actuation members longitudinally. The flexible distal portion is configured to deflect away from the longitudinal axis in response to translation of the first and second translatable actuation members longitudinally. The dilation catheter is slidable relative to the shaft assembly and includes an expandable dilator.
