Abstract

A surgical guiding instrument for use with a chisel and an implant body for insertion into an intervertebral space, included is a shaft with a stop device for delimiting a depth of insertion of the implant body into the intervertebral space. The shaft has a distal end and a proximal end, the implant body being arranged at the distal end of the shaft and defining two bearing surfaces positionable against the adjacent vertebral bodies, the stop device having at least one stop movably mounted at the distal end of the shaft or on the implant body, the stop having a stop surface pointing in distal direction transversely or substantially transversely to at least one of the bearing surfaces, so that an insertion depth for a surgical machining tool can be set in a simple way.
