A method of making the tubular body of a steerable arm for use in an endoscopic surgical procedure, comprising the steps of:
- providing a hollow metal tube and configuring the hollow metal tube into a tubular body having a plurality of ribs along at least one side of the tubular body, the ribs extending from a spinal portion;
- inserting at least one wire into the tubular body;
- bending the tubular body with the wire inside;
- heating the bent tubular body with the bent wire inside;
- such that
- the tubular body and the wire memorise their respective bends.
