The present invention relates to a device for positioning a jig at a structure using at least one fixing element comprising at least one adjusting element which can directly interact with or guide the at least one fixing element and which can interact with the jig, so that the relative position between the at least one fixing element and the jig can be adjusted by changing the position of the at least one adjusting element, as well as to a method for positioning a jig at a structure comprising two rotatable adjusting elements, wherein the resection plane of the jig can be moved along or in a first direction when the adjusting elements are moved in the same direction and wherein the resection plane is turned if the adjusting elements are moved in an opposite or different direction or only one adjusting element is moved.
