An instrument for endoscopic applications comprising a tube like member that includes three coaxial cylindrical members, namely an inner (2), an intermediate (3) and an outer (4) cylindrical member. In particular, the intermediate cylindrical member comprises a first rigid intermediate member end part (31) at the handling end portion (141) of the instrument, and a second rigid intermediate member end part (35) at the actuating end portion (145) of the instrument. The first and second rigid intermediate member end parts are connected to each other via at least three longitudinal elements (38) in such a way that the at least three longitudinal elements control a radial deflection of the handling end portion by a radial deflection of the actuating end portion through a movement of the at least three longitudinal elements in a longitudinal direction. The instrument according to the invention enables a less complicated assembly of the instrument.
