    摘要: A trocar sleeve has a hollow shaft having a distal end and a proximal end, the shaft having a rectilinear shaft axis, an external thread rising from an outer surface of the shaft, wherein a first external thread having a shape of a helix has a height, measured from the outer surface up to a vertex of the helix, the height of the helix, seen along the rectilinear shaft axis from distal to proximal increases, and wherein a pitch of the helix, seen along the rectilinear shaft axis from distal to proximal decreases.
