In order to improve a surgical instrument for removing an intervertebral implant from an intervertebral space of a human or animal spinal column, comprising a coupling part arranged at the distal end of the instrument for placement on the intervertebral implant in a placement position, the coupling part being able to be brought from the placement position into a coupling position in which the intervertebral implant is held with force locking and/or positive locking on the coupling part, the coupling part comprising at least one first coupling element and at least one second coupling element, which are engageable with the intervertebral implant in the coupling position, so that it may also be used for removing different intervertebral implants of different sizes and shapes, it is proposed that the at least one first coupling element and the at least one second coupling element be arranged so as to be movable relative to each other in such a way that a spacing between the at least one first coupling element and the at least one second coupling element in a direction parallel to a longitudinal axis defined by the instrument is alterable for transferring the instrument from the placement position to the coupling position and/or vice versa.
