Abstract
A medical tool includes, a deflectable distal end, at least a pull wire, and a coupling element. The at least pull wire has a first end coupled to the distal end of the medical tool, and configured to be moved for deflecting the distal end. The coupling element is coupled to a second end of the pull wire and having at least two boreholes configured to receive at least two respective rods traversing therethrough. The coupling element is configured to be moved along a rotation axis of a rotatable element coupled thereto, and the boreholes and the respective rods are configured to prevent rotation of the coupling element.

A medical tool, comprising:
- a distal end that is deflectable;
- at least a pull wire, having a first end coupled to the distal end of the medical tool, and configured to be moved for deflecting the distal end;
- and
- a coupling element, which is coupled to a second end of the pull wire and having at least two boreholes configured to receive at least two respective rods traversing therethrough, wherein the coupling element is configured to be moved along a rotation axis of a rotatable element coupled thereto, and wherein the boreholes and the respective rods are configured to prevent rotation of the coupling element.
A method for producing a medical tool, the method comprising:
- providing a distal end that is deflectable;
- coupling, to the distal end of the medical tool, a first end of at least a pull wire to be moved for deflecting the distal end;
- coupling, to a second end of the pull wire, a coupling element having at least two boreholes, and inserting at least two respective rods traversing through the at least two boreholes;
- and
- coupling, to the coupling element, a rotatable element for moving the coupling element along a rotation axis of the rotatable element, wherein the boreholes and the respective rods prevent rotation of the coupling element.
