摘要

The tube (1) has a set of steering wires (3, 4) controllably steering a tip (2) of the tube in different directions. Additional control wires (5, 6) bend the tip in a direction that is opposite to a direction in which the tip is steered by the steering wires. The steering wires comprise threads or bodies that contract or expand under the influence of an electric current or pressure change.
