Abstract
Surgical instrument for inserting an intervertebral endoprosthesis consisting of two prosthesis plates and a prosthesis core. The instrument has two prosthesis holders open at the ends that can be spread apart from each other. In order not to have to remove the instrument from the prosthesis with the latter being under unfavourable loading, it is provided with a withdrawal device which bears on the prosthesis and/or on an associated vertebra. The withdrawal device comprises a slide having a prosthesis limit stop for the prosthesis located in the guide and/or a vertebral limit stop for a vertebra which is to be connected to the prosthesis. The slide is displaceable in a slide guide between a retracted end position and an advanced end position by an actuating device.
