摘要： 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.

摘要： An endoscope and shaft system include an access shaft and an endoscope which can be inserted into the access shaft, the proximal end of the access shaft has a grip part, and the endoscope is held in a connecting piece. The connecting piece can be detachably connected to the grip part, and the connecting piece can be rotated about the longitudinal axis of the endoscope relative to the grip part when the connecting piece is connected to the grip part.
