1. A medical apparatus for parallel alignment of at least two medical instruments, defining an instrument longitudinal axis, for holding and manipulating a surgical fastening element, which fastening element comprises a fastening part and a holding part for a connection element, the holding part being mounted movably relative to the fastening part in a mounting position, which medical instruments have a distal end couplable to the fastening element, which apparatus comprises at least two coupling devices, each defining a coupling longitudinal axis, for temporary coupling with proximal ends of the at least two medical instruments, wherein the apparatus comprises a frame, wherein the coupling longitudinal axes of the at least two coupling devices are alignable parallel to one another, wherein in a mounting position the at least two coupling devices are held in such a way as to be movable relative to one another and on the frame and wherein in an alignment position they are held immovably relative to one another and on the frame,
wherein each of the coupling devices comprises at least two coupling members, which in the mounting position are held so as to be movable relative to one another and on the frame and which in the alignment position are held immovably relative to one another and on the frame,
wherein the coupling device comprises a locking device for at least one of securing a position and alignment of the coupling members in the alignment position,
wherein the locking device comprises a clamping or blocking device for clamping securing of the coupling members on the frame in the alignment position or for blocking movement thereof relative to one another, and
wherein the clamping device comprises at least one clamping member for clamping securing of the coupling members on the frame in the alignment position, wherein the at least one clamping member takes the form of a spring element.
