<p>The material used for the production of the elastic shaft (28) is made of a multitude of rings touching each other and forming shapes with three circular outer areas joined in the center. The arrangement of the shapes results in an elastic but form-retaining material. The shapes can expand and contract without collapsing completely facilitating the guiding of the shaft (28) through curved areas inside the body without its walls (30) interfering with the wire accommodated inside.</p> |
