Abstract:
Actuator elements such as cables or push rods in an instrument are used for manipulating an end effector or distal end of the instrument. Each actuator element extends within a tubular housing and either the tubular housing is axially rotated about the actuator element or the actuator element is axially rotated within the tubular housing to reduce at least one force opposing an axial force exerted through or movement of the actuator element.
