Suzor forceps instrumented with markers placed at the level of the handle extremity (M1), the heel (M2), the inferior (M3) and superior part of the blade (M4), and the toe of each blade (M5). A cluster of markers (MT1), used to define the technical coordinate system, was also placed at the handle extremity. The indicator in red represents the virtual marker (MV), in the middle of markers 3 and 4, used to define the different delivery phases
