PROBLEM TO BE SOLVED: To provide a medical instrument and a vertebral column stabilization system capable of releasing the instrument from a holding part of a securing element again in a simple manner.SOLUTION: A medical instrument for holding and handling a surgical securing element has a proximal and a distal end. The surgical securing element includes a securing part and a holding part for a connection element which is assembled to be movable in relation to the securing part in an assembled disposition. The instrument defines a longitudinal axis, and includes a pulling part and a pushing part movable in relation to the pulling part in the direction of the longitudinal axis. The proximal end is temporarily couplable to the securing element in the assembled disposition. For improvement to allow the instrument to be released from a holding part of a securing element again in a simple manner, the instrument includes an uncoupling device 162 for actively transferring the instrument from a coupled position, in which the pulling part and the holding part are coupled, to an uncoupled position, in which the pulling part and the holding part are separable from one another.【課題】器具を固着要素の保持部から再度単純なやり方で解放できる医療器具及び脊柱安定化システムを提供する。【解決手段】固着部と、組立状態のときに固着部に対して移動可能であるように組み立てられる接続要素用保持部とを含む外科用固着要素を、保持及び操作するための医療器具であって、器具が、近位端及び遠位端を有し、かつ、長手軸を規定し、かつ、引張部と、引張部に対して長手軸の方向に移動可能である押圧部とを含み、組立状態のときに、近位端が固着要素に一時的に連結可能である、医療器具を、固着要素の保持部から単純なやり方で再度解放できるように改良するために、この医療器具が、引張部及び保持部が連結される連結位置から、引張部及び保持部が互いから分離可能である非連結位置へと、器具を能動的に転移させるための連結解除装置162を含む。【選択図】図9
