Abstract:
1. Surgical set comprising: a bone plate fixing device comprising a first bone contacting element with a rod-shaped connecting member projecting from the first bone contacting element and defining a longitudinal direction, the connecting member consisting of a first portion and a second portion, the first portion having a first maximum diameter and the second portion consisting of a projection protruding from the connecting member, the projection located towards a proximal end of the connecting member and having a second maximum diameter that is greater than the first maximum diameter, the projection having a projection toothing comprising at least two teeth, and a second bone contacting element displaceable on the connecting member in a direction towards the first bone contacting element, and a surgical instrument for applying the bone plate fixing device, the surgical instrument comprising a first tool element positionable in a contacting position on the second bone contacting element, and a second tool element removable from the first tool element, with a transportation device for stepwise transportation of the connecting member with the second tool element in several transportation steps in a proximal direction away from the first tool element resting in the contacting position on the second bone contacting element, wherein the second tool element has toothing comprising a plurality of teeth forming several receptacles for the projection protruding from the connecting member, with each transportation step the projection is at least partly engageable with a receptacle in an engagement position and is held therein immovably in longitudinal direction on the second tool element, and from one transportation step to a following transportation step the projection is engageable with a receptacle arranged in a more proximal direction on the second tool element; wherein the toothing of the second tool element has a pitch which corresponds to an integral multiple of a pitch of the projection toothing.
