A surgical guiding instrument for a surgical machining tool has a substantially elongated instrument body having a proximal end and a distal end and defining a longitudinal axis. The instrument body carries a guiding device for the machining tool that can be used in minimally invasive surgery. The guiding device is arranged and constructed so as to enable the machining tool to be positively guided by it along a path of movement defined by the guiding device. The path of movement corresponds to a superimposed translational-pivotal movement.
