Abstract
A trocar sleeve includes a distal tubular section, a section which connects to the distal tubular section at a proximal side of the distal tubular section and which is widened proximally, and at least one spiral with a circular outer contour, arranged helically on a periphery of the distal tubular section. The distal tubular section includes a rounded polygonal cross section so that maximal degrees of freedom of the applied instruments result.
