A DEVICE FOR MANIPULATING A BONE OR BONE FRAGMENT OR A SURGICAL INSTRUMENT, TOOL OR IMPLANT AND A METHOD FOR POSITIONING SUCH A DEVICE

摘要

A device and a method for surgically manipulating a bone or bone fragment or a surgical instrument, tool or implant. Said device comprising: A) a rod shaped member (2) with a central axis (6), a rear end (3), a front end (4) and a length L2; B) a first targeting element (7) fixed to said rod shaped member (2) coaxially to said central axis (6) and having a first center (46), wherein said first targeting element (7) is arranged on said rod shaped member (2) with said first centre (46) at a distance A1 > 0 from said rear end (3); C) a second targeting element (5) with a second center (45), wherein - said second targeting element (5) is fixed to said rod shaped member (2) coaxially to said central axis (6) with said second centre (45) at a distance A2 < A1 from said rear end (3); or - said second targeting element (5) is joinable to a surgical instrument or tool which is displaceable parallel to said central axis (6) with respect to said rod shaped member (2) so that said second targeting element (5) remains coaxial to said central axis (6); and wherein D) said first targeting element (7) has a diameter DK measured orthogonal to said central axis (6) of minimum 10 mm.
