Abstract
A bone screw has a threaded screw shank and a screw head that in turn has two opposite legs defining a receptacle between them and integrally connected to a tissue-protecting sleeve. The tissue-protecting sleeve has a slot that runs from the sleeve's one edge to the opposite edge. Further, a sleeve remover has a corpus structured as a hollow cylinder, which has a separation element at one end, on its inside circumference, which element extends over part of the circumference direction.
