  • Shaft deflection control assembly for ENT guide instrument
    Patent number: 11964114
    Abstract: An apparatus includes a body, a shaft assembly, and a deflection actuation assembly. The shaft defines a longitudinal axis and includes a flexible distal portion. The deflection actuation assembly includes a first rotary actuator, a translatable actuation member, and a resilient member. The translatable actuation member extends through the shaft assembly and is operatively coupled with the first rotary actuator and the flexible distal portion of the shaft assembly. The first rotary actuator is rotatable by a rotational force to thereby drive the translatable actuation member longitudinally. The resilient member is positioned between the first rotary actuator and the body and is configured to apply a friction force between the first rotary actuator and the body. The friction force is operable to increase the rotational force required to rotate the first rotary actuator.
