Insertion system

Abstract

An insertion system comprising at least one screw coupling configured for coupling at least one first element and at least one second element of the insertion system is disclosed. The screw coupling is configured such that the first element and the second element are assembled without rotational movement. The screw coupling comprises at least one radially flexible part configured for radial movement and/or deformation when assembling the first element and the second element, wherein the radially flexible part is a part of the first element or second element; and elastic means configured for applying a force in an axial direction to the screw coupling, wherein the elastic means is pre-loadable in the axial direction during assembly of the insertion system.
