摘要：
A method for transmitting torque and variably flexing an insertion device for receiving an instrument includes the steps of providing a hollow body, transmitting torque along the hollow body with a corrugated tube, applying suction to create a vacuum in the hollow body for placing the hollow body in a relatively stiff condition, relieving the vacuum for placing the hollow body in a relatively flexible condition, maintaining the hollow body in the relatively flexible and relatively stiff conditions with tendons disposed within the hollow body, and individually adjusting at least some of the tendons in length for steering a distal end of the hollow body.
