The trocar mandrel (10) is provided with shaft-like elongated mandrel bodies (14,16) having tips (18,20) at its distal end, where a proximal end has a head (12). The latter longitudinal shaft-like mandrel body is arranged at the head such that the mandrel body extends away from the head with a distance (A). The shaft-like mandrel bodies contain different diameters. |
