摘要

The surgical sealing elements (52, 54), in particular, for a trocar (12) and/or shafts of elongate surgical instruments comprise flexible walls which are foldable so that wavy sealing lines (84, 86) lying entirely on a cylindrical surface are produced. Independent claims are also included for: (A) a surgical sealing unit with the proposed sealing element; (B) a surgical sealing system with a surgical sealing unit for introduction of surgical instruments into a human or animal body.
