ABSTRACT:
In order to improve a surgical sealing element, in particular, for a trocar and/or for sealing shafts of elongated surgical instruments during insertion into a human or animal body, wherein the sealing element defines a longitudinal axis, is provided with an opening, which is variable in diameter and is oriented transversely or essentially transversely to the longitudinal axis and through which an instrument can be inserted, and comprises a flexible wall which is closed annularly, wherein the wall has a first and a second edge each closed upon itself and wherein the first edge limits the opening, such that all instruments currently available can be reliably sealed irrespective of the diameter of their instrument shaft it is suggested that the wall be foldable in a wave-like manner and in a sealing position be folded in a wave-like manner without kinks with fold lines extending in the direction towards the first edge in such a manner that the first edge defines a wave line which is located entirely on a cylindrical surface.
