摘要

The surgical instrument (10), for the insertion of a disk implant (12) into the space between two vertebra of a human or animal spine, has a shaft (50) defining the longitudinal direction (44) with at least two laying unit holders (62,64) at the distal end for the laying units (14,16). A vertical spacer (130) has movement in relation to at least one of the two holders, to keep the laying units at a defined gap from each other.
