Abstract

The invention relates to a device (20, 30) for determining the position of an incision block (1, 10) comprising: a positioning element (21, 31) with at least one reference point (22a, 22b, 22c; 33a, 33b, 33c), whose spatial position can be detected; and a position determining element (24a, 24b; 34) which is firmly connected to the positioning element (21, 31), as well as to a method for determining the position of an incision block, wherein: the location of a positioning element (41) on a body structure, in particular on a bone, is detected; the location of a positioning element (21, 31) for positioning a position determining element (24a, 24b; 34) is detected; and the relative location of an incision block (1, 10) to the body structure is determined from the location of the positioning element (41) and the location of the positioning element (21, 31).
